Replacement Window Installation Day

Factory Trained Window Technicians

Replacement window installation day arrives!

Our factory certified window crew arrives and begins the process by checking all of the new replacement window measurements against the openings in the home before any old windows are removed.  The team also inspects each window for any imperfections.  Imperfections can include:

  • Frame damage
  • Glass stress fractures
  • Broken hardware
  • Scratches of any kind

Once the measurements are verified and the windows have been assessed and no issues are present the installation truly begins.

The Window Installation Steps

Removal of Old Windows
Different types of windows require different techniques for removal.  For example, metal aluminum windows are more difficult to remove compared to wood windows. 


Types of Windows that are Removed

  • Metal Windows
  • Aluminum Windows
  • Vinyl Windows
  • Wood Windows
  • Fiberglass Windows


Generally, regardless of what type of window is being removed, the technician will first remove the old storm windows (if applicable), window sashes and screens first.

Once the individual components have been removed from the old windows, the next part of the window to be taken out is the existing window mainframe.  After removing the window mainframe, there is varying amounts of dust and debris that must be removed depending on the age of the home, the size of the opening and the type of material that is in the existing window.

Once the opening is clear of the old existing window our installation team cleans the window opening so that it is free of any debris prior to insertion of the new replacement window.  This ensures a tight fit as the window was measured and intended to be.  Cleaning the opening also allows the foam sealant to properly expand in the cavity and seal the new window from air leakage.  Caulking also performs better when it is applied to a dry, clean surface.

Securing the New Windows into Openings
Technicians insert the new vinyl replacement window into the cleared opening and secure the new replacement window to the frame of the home with stainless steel screws.  During this part in the installation process, it is critical to be sure the window is installed level so that all of the moving parts are balanced properly for smooth operation.  If the window is not level during this stage in the installation then it will not function properly.  This is a good fail-safe for making sure that when the window is finally sealed there are not issues with it being level and properly secured to the opening.

Sealing Replacement Windows
Technicians use high quality low expanding foam insulation between the window frame and the rough opening frame of your home to seal all gaps. 

Next, we install an exterior capping package made from a special maintenance-free material that is carefully measured and formed to completely seal the outside trim around the window.

The installation crew then uses a high quality replacement window caulk that is specially formulated for exterior use in the Mid-Atlantic region.

Finally, we use an acrylic caulk on the inside of the home to further seal your new replacement windows as well as finish the installation process neatly and professionally.

Capping is intricately measured and cut to overlap and seal windows. High quality cualk finishes the job.
