I invite you to explore my YouTube channel, where you'll see first-hand how insulation looks in dark and mysterious attics, crawl spaces, and basements scattered across Maryland. Witness first-hand how we tackle the unique challenges found in these hidden spaces, and gain valuable knowledge on how to conquer your own house.
Written by Eric Gans, Building Analyst & Envelope Professional I'm a certified energy auditor and insulation contractor in Maryland. I have completed over 2,000 energy audits and taken over 2,000 trips to attics.
Does one room in your home always feel too hot or too cold?
The problem might be your attic hatch — a small, often overlooked gap that could be quietly sabotaging your home’s comfort and efficiency.
In this step-by-step DIY guide, I’ll show you how to seal and insulate your attic hatch using rigid foam board and a few affordable tools. It’s a quick project with a big payoff in any house that has an access panel connected to an attic. It might be on the ceiling or a wall.
Thermography reveals that the attic hatch is connected to the attic.
Why Insulating Your Attic Hatch Matters
Your attic hatch may look like a minor detail, but it can have a significant impact on your home’s thermal performance. If left uninsulated or poorly sealed, it creates a weak point in your attic’s defense system.
Here’s what happens when it’s ignored:
Warm or cool air escapes through the hatch, increasing HVAC workload.
Rooms near the hatch become drafty or uncomfortable.
The entire attic’s effective R-value drops, even if the rest of the attic is well-insulated.
For example, in a 1,000 sq. ft. attic, just 18 sq. ft. of missing insulation at the hatch can reduce the R-value from R-17 to R-13.

Weatherstripping: 3/8" wide, 3/16" thick, ~17 feet long Get it Here
Also, grab a:
Tape measure
Marker or pencil for layout lines
A clean rag to wipe dust and debris
Step-by-Step: How to Seal and Insulate Your Attic Hatch
1. Inspect Your Existing Hatch
Pop it open and see what you’re working with. You may find:
No insulation at all, or
Old foam board that's thin or poorly attached
Either way, you can improve it — and now’s the time.
2. Clear & Prep the Surface
Remove any old insulation, staples, nails, and debris
Wipe down the surface to ensure your adhesive sticks properly
Tip: A clean surface = better long-term performance.
3. Measure & Cut the Foamboard
Measure the hatch panel, but leave a small gap around the edge so the panel fits back into the opening easily
Cut your rigid foamboard with a long knife
Stack the layers until you reach the desired R-value. In Maryland, I used four layers to achieve an R-52 rating.
4. Attach Insulation to the Hatch
Use foam board adhesive (PL 300) to glue the layers directly onto the panel.
Let it cure flat to prevent bowing.
This ensures the insulation stays in place, even when accessing the attic repeatedly.
5. Apply Foil Tape for Durability
Use echo tape, not duct tape
Tape around all edges of the insulation for a tight seal and a clean look
Tip:Duct tape will fail in an attic. It breaks down from heat and dust.
6. Install Weatherstripping
Apply foam weatherstripping along the attic opening’s lip
Mark where the hatch sits so the weatherstripping doesn’t get in the way
A tight seal here prevents air leakage, especially during the winter stack effect.
Pro Insight from an Energy Auditor
In my years of performing energy audits in Maryland, I’ve walked into countless homes where a single room felt noticeably colder or hotter. Almost every time, the culprit was right above — the attic hatch.
If you see:
Spider webs near the hatch, or
Discolored insulation above the panel
…those are signs of airflow and energy loss.
Fixing it with a DIY project like this one is one of the most cost-effective upgrades you can make.

Written by Eric Gans, Building Analyst & Envelope Professional I'm a certified energy auditor and insulation contractor in Maryland. I have completed over 2,000 energy audits and taken over 2,000 trips to attics.
Did you know that at any given time, there are around 40 contractors approved by BGE & PEPCO to perform energy audits across Maryland?
Sounds like a lot of options, right? But here’s the reality:
Not every audit is created equal.
And not every auditor sees your home the same way.
Now and then, I get a call from a Maryland homeowner who has already had their audit done but wants a second opinion. When that happens, and they authorize it, I can access their previous file through the BGE/PEPCO system.
And to be totally honest?
I’m amazed at how many audits I review that barely scratch the surface.
Some are missing key findings. Others are just boilerplate. Very few include real-world insights that empower the homeowner to make informed decisions.
A great energy audit isn’t about checking boxes—it’s about telling the story of your home. And to do that well, the person holding the clipboard needs more than just a license.
They need experience.
They need curiosity.
They need to care.
So, how do you make sure the person showing up at your house is the right one?
Start by asking these five questions—yes, even if you’re talking to me.
1. How many BGE energy audits have they completed?
Experience matters. An auditor who’s done 50 homes won’t catch the same patterns as one who’s done 500. Every audit requires time in the attic, time at the rim joist, and time listening to you. A seasoned auditor knows how to balance the technical checklist with real-time problem-solving.
Your $100 audit? It’s a one-shot deal at the discounted price. Make it count.
2. What’s their background before becoming an auditor?
Not all auditors are cut from the same cloth. Some came from the HVAC world. Some from sales. Me? I started in home contracting. Replacement windows, vinyl siding, gutters, entry doors, and, these days, insulation. I’ve lived the problems I help solve now.
Ideally, your auditor should understand homes from the inside out, not just from behind a laptop screen. Bonus points if they’re also a homeowner. Because when you’ve lived with a cold baby’s room or an icy kitchen floor, you don’t need a manual to know where to look.
3. What kind of detail will be in the final report?
Yes, BGE provides a standard template. But the magic is in the details.
A mediocre report feels generic—like it could’ve been written for any house. A great report reflects your home. It echoes your questions. It includes photos, recommendations, and context that make it a valuable reference, not just a PDF you’ll forget about.
4. What’s the physical condition of the auditor? (Yes, really.)
This job isn’t for the faint of heart or knees.
A thorough audit requires crawling through tight crawlspaces, climbing into sweltering attics, and inspecting every inch of the home’s shell. If your auditor can’t (or won’t) go where the problems hide, how can they find what’s going on?
Great energy audits don’t happen from the living room couch.
5. Can they communicate clearly and care enough to explain?
This is the big one.
A great auditor isn’t just a building scientist. They’re also a teacher—someone who can simplify technical concepts without dumbing them down.
If the person can’t explain the stack effect, duct leakage, or R-value in plain English, the report won’t help you. And if they don’t take the time to answer your questions, you’ll be left with more doubt than direction.
Bottom Line: Choose Your Auditor Like You’d Choose a Doctor
Your home is a system. And just like with your health, understanding what’s going on takes more than a glance. It takes the right person asking the right questions, in the right way.
So before you book your BGE energy audit—ask a few questions of your own.
And if you want someone who will crawl through the attic, listen to your concerns, and give you the full picture?
Often times homeowners don't know what a Pepco energy audit is or how it can actually help.
For starters, a Pepco energy audit can help you avoid choosing the wrong solution to a problem around your home. An energy audit through Pepco is a good place to start a home improvement priority list.

I have completed over 2000 home energy audits in Maryland. BGE and Pepco standards require me to measure exhaust ventilation rates and determine where each exhaust fan in a residential house terminates. I must also manage new fan installs and airflow at the end of home performance projects to maintain indoor air quality. So, I am around this stuff every day.
Bathroom exhaust fans are crucial in maintaining indoor air quality by removing moisture, odors, and airborne contaminants. Yet, when these fans malfunction or require replacement, many homeowners are uncertain about which type of contractor to call.
This article explores the different contractors available for this task and why a home performance contractor might be your best bet.
Types of Contractors Who Replace Bathroom Exhaust Fans
Understanding the roles and capabilities of different contractors is essential in making the right choice for replacing your bathroom exhaust fan.

Holistic Integration: They understand the importance of a tight building envelope and the role of ventilation in maintaining a healthy indoor environment. This knowledge helps them integrate the fan seamlessly into the home’s systems.
Quality Assurance and Follow-Up
Thorough Testing: After installation, home performance contractors perform detailed testing to ensure the fan operates efficiently and does not introduce air leaks. They measure the airflow and inspect the installation to confirm everything is functioning as expected.
Post-Installation Support: They often provide follow-up visits to check the fan’s performance and address any issues, ensuring long-term satisfaction and performance.
Integration with Other Home Systems
Energy Efficiency Focus: Home performance contractors look at the big picture, considering how the new fan will impact your home’s energy usage. They can recommend improvements like air sealing or duct insulation to enhance efficiency.
Optimized Solutions: Ensuring that all systems work harmoniously helps maintain optimal indoor air quality and comfort levels throughout your home.
Choosing the Right Contractor for Your Needs
Selecting the appropriate contractor for your bathroom exhaust fan replacement depends on your needs and the project's scope.

Discover why partnering with Hometrust Remodeling, Maryland's leading residential insulation expert, can transform your home’s comfort and energy efficiency.
The Importance of Insulation
Insulation is a critical component in your home’s energy efficiency. It works by slowing heat transfer between the house's interior and exterior. In the summer, insulation helps keep the heat out, and in the winter, it keeps the warmth in. This enhances comfort and significantly cuts down on heating and cooling costs.
Achieving the desired insulation level: Proper materials and installation to meet energy efficiency goals.
Attention to detail: Precision in every step to maximize effectiveness.

CASE STUDY: Enhancing Comfort in a Cape Cod
Michael had lived in his family’s Cape Cod-style home since birth. Over the years, he experienced significant discomfort due to temperature fluctuations and high energy bills. Michael turned to Hometrust Remodeling, Maryland's trusted residential insulation expert, seeking a permanent solution.
Home History and Challenges
Michael’s home, built in the 1950s, had significant insulation gaps and air leaks, especially in the attic and knee walls. These issues caused drastic temperature differences between floors and high energy bills.
The Home Energy Audit
Our team conducted a thorough energy audit using advanced diagnostic tools, including thermal imaging and a blower door test. We identified an air leakage rate of 5571 CFM50, indicating substantial energy loss.
Designing Cost-Effective Solutions
We recommended comprehensive air sealing and the addition of high R-value insulation in the attic, knee walls, and crawlspace. This approach aimed to reduce air leakage to 3500 CFM50 and insulate key areas to R49 at the flat and R38 at the slope, saving Michael $644 annually in energy costs.
Executing the Plan
Our team implemented the recommended solutions by sealing all major air leaks and installing new insulation. The project was completed in two visits, ensuring minimal disruption to Michael’s daily life.
Achieving Results
Post-implementation tests showed a significant improvement. The blower door test recorded a 34% reduction in air leakage from 5571 CFM50 to 3671 CFM50. Michael’s feedback highlighted the improved comfort and energy efficiency, with a much more consistent temperature throughout his home.

The Cape Cod Life
Michael had lived in his family’s Cape Cod-style home since birth. Over the years, he experienced significant discomfort due to temperature fluctuations and high energy bills.
He sought a permanent solution and turned to Hometrust Remodeling for a comprehensive energy audit.
Watch the interview on YouTube
Home History and Challenges
Michael’s home, built in the 1950s, is a typical Cape Cod style with a conditioned basement and 2367 square feet of total living space. Initially, comfort issues were minimal on the main floor, but as Michael moved to the upper floor, the extreme temperature differences became more noticeable, especially in the summers and winters.
Realizing the Need for a Home Energy Audit
Understanding the importance of a detailed energy audit, Michael sought professional help. He had tried various temporary fixes like weather seals and space heaters but realized a comprehensive solution was needed to address the root causes of his home's inefficiencies.
Conducting a Comprehensive Home Energy Audit
Our team conducted a thorough energy audit using advanced diagnostic tools, including thermal imaging and a blower door test. We inspected key areas such as the attic, knee walls, and crawlspace to identify significant insulation gaps and air leaks.
The audit measured an air leakage rate of 5571 CFM50, indicating substantial energy loss. One way to think about it is air changes per hour.
How many times does the volume of air inside the home exchange with the outside air in one hour? Brand new houses have to be equal to or less than 3 ACH.
Given the volume of living space inside Michael's home (18,936 cubic feet), we calculated the Air Changes Per Hour (ACH) to be approximately 17.65 ACH. This was calculated using the formula:
Here is how it works out for Michael's house:
CFM50 is the airflow in cubic feet per minute at 50 Pascals (5571 CFM50) x 60 (minutes per hour)
Volume is the volume of the house in cubic feet (2367 sq. ft. × 8 ft. ceiling height = 18,936 cubic feet)
This high ACH value confirmed significant air infiltration, necessitating extensive remediation.
Identifying Critical Issues
The audit revealed several critical issues: insufficient insulation in the attic and knee walls, significant air leaks around the foundation in the basement, and uninsulated areas in the crawlspace. These factors contributed to the drastic temperature differences between the floors and high energy bills.
Michael’s home showed an annual energy cost of approximately $2553, with significant portions attributed to space heating and electric baseload.
Designing Cost-Effective Solutions
To address these issues, we recommended comprehensive air sealing and the addition of high R-value insulation in the attic, knee walls, and crawlspace. Specifically, we aimed to reduce air leakage to 3500 CFM50 and insulate key areas to R49 at the flat and R38 at the slope. These improvements were expected to save Michael $644 annually in energy costs.
Financial Feasibility and Incentives
The total project cost was initially estimated at $6334. However, with the help of the PEPCO program, which offered substantial rebates and incentives, Michael’s out-of-pocket expense was significantly reduced to $1583.50. This made the project affordable and cost-effective, with a simple payback period of 2.5 years and an annual rate of return of 40.66%.
Executing the Plan
Our team implemented the recommended solutions by sealing all major air leaks and installing new insulation. The work included treating major attic bypasses and insulating accessible knee walls with foam and air barriers.
The project was completed in two visits, ensuring minimal disruption to Michael’s daily life.
Achieving Results
Post-implementation tests showed a significant improvement. The blower door test recorded a 34% reduction in air leakage from 5571 CFM50 to 3671 CFM50. This improvement translated to enhanced energy efficiency and substantial savings on energy bills.
Michael provided feedback after the work was completed:
"They’re a lot better than last year. I bought a Google temp sensor that pairs with my thermostat, and so far, the only difference between upstairs and downstairs is 4-6 degrees, and that’s most probably from heat rising and solar gain. The humidity problem has drastically reduced, and for the most part, I can get away with just cooling off with a fan, even with it being 86 outside. Probably a bit down the line, we’ll look into upgrading the HVAC system and switching out the single-pane windows (there’s some leakiness due to how thin they are). Thank you again for everything!

Michael’s case highlights the transformative impact of a thorough energy audit and proper insulation on home comfort and efficiency.
For homeowners experiencing similar issues, a comprehensive energy audit is a crucial step toward a more comfortable and energy-efficient home. By addressing the root causes of energy loss, significant improvements in comfort and cost savings can be achieved.
"It's these little things hidden behind the drywall or the ceiling that you don't think about. After seeing the report and realizing how much insulation was missing and where the major air leaks were, it all made sense. The audit helped me understand the root problems, and now the house is much more comfortable and energy-efficient." Michael - Lives in Cape Cod House

Maryland Home Insulation Guide
An under-insulated attic is the #1 reason for poor home comfort and high energy bills. Use this guide for Maryland home and attic insulation solutions.
Well-Insulated Attic
3 Characteristics
1. No significant gaps
2. Fits in any cavity
3. 13-18" Depth
Does that look or sound like your attic insulation?
Not likely...ENERGY STAR says 9 out of 10 homes are under-insulated, and everything I see in Maryland attics proves it.
According to a recent Forbes Magazine article, there are approximately 124 million houses in the United States, and roughly 20% were built before 1980. Older homes mean older, outdated methods of insulating that don't measure up to today's standards.
So where do you begin? This guide can help. It will answer many of the questions homeowners have about insulation.
If your home is older than ten years, then you are likely not meeting the 2024 Maryland home insulation building code. If you see insulation, it does not mean it is working for you.
You gotta know what to look for...
The State of Maryland recommends that our attics have enough insulation to equal R-49.
The existing insulation in a Maryland attic is inconsistent for various reasons. Air sealing and insulation are essential for a tight, energy-efficient home.

Insulation Guidance Tools
Tool # 1 The R-Value Calculator Use this helpful tool to determine your current attic R-value and assess your protective barrier's performance against current recommendations.
You need to take two steps for this tool to work.
STEP 1: Get Your Attic's Current R-Value
Tasks Required
1. Determine the type of insulation you have in the attic now.
2. Determine your current insulation level in inches and note any areas (up to three) with major level variants.
3. Determine the condition of your current insulation.
STEP 2: Calculate Your Attic Area
Tasks Required
1. Measure the length and width from below for any attic area to calculate the square footage.
2. Note the exact square footage of any area with different insulation levels (up to three). Use a laser measure to make it easy!
Once completed, you will be much closer to knowing if you are up to the Maryland building code and ENERGY STAR.
The insulation your attic needs will depend on how much is there now. Getting it right will ensure you earn the best return on your investment (ROI) and meet the 2024 Maryland building codes.
This can be a little tricky. Calculations can be off if the information is not gathered right. The condition, coverage, and depth of the insulation are each important.
Take notice if you have any area in your attic that does not have insulation.
One example is 18 square feet of uninsulated area in a 1000-square-foot attic. It reduces the R-value. Missing insulation will lead to comfort problems and high energy bills.
REASON:
According to Dr. Allison Bailes of Energy Vanguard, the heat flows through the bare areas fast. He says warm air leaves in the un-insulated ceiling area 38 times faster than in the insulated areas.
It is essential to measure insulation through a different lens. Try not to focus on which insulation is better. Instead, please focus on the proper R-value, especially for the places where it is most important.
There are two things to know about R-value:
1. How to Measure R-Value
Insulation has one job - to resist heat flow. The higher the R-value, the better the insulation resists heat transfer.
2. How R-Value Requirements Change
As your home's features twist and turn, insulation requirements change. R-values decrease in less critical areas.
Batt Insulation: Prevalent and, unfortunately, the worst performer.
How Much Does Insulation Cost?
Home performance contractors look for insulation fixes in existing homes that will make the most impact at the lowest cost. Accessible areas are the first priority and usually the most important. Investigation and testing help shape solution decisions. Taking this approach will factor in the overall cost.
Here are important considerations if you plan to insulate your home:
ENERGY STAR® recommends examining the many systems around your home. Evaluating the "whole house" can lead to better comfort and efficiency. Their statistics show that 9 out of 10 homes in the U.S. are under-insulated.
Maryland Utilities (BGE & Pepco) offers a portfolio of programs promoting energy efficiency and conservation, including rebates, education, and services. The programs are designed around a consultative approach.
Air sealing and insulation are the most critical measures to achieve energy efficiency—before windows and doors and replacing older HVAC. Getting a home energy audit is the initial qualifier for rebates.
Why is the room on the front of the house colder? Do you have enough insulation? Why is it so stuffy upstairs during the summer? Should I remove old insulation from my attic? Why does my HVAC run all of the time? Is spray foam insulation the best solution for my home? Why are my new windows feeling drafty? Do my walls have insulation?
