Installation Methods
Retrofit Installation
Perfect for existing homes, retrofit installation involves replacing your old windows and doors while preserving existing frames and finishes when possible.
New Construction Installation
New construction installation involves complete frame replacement and can be used for both new builds and existing homes.
Important Note: New construction can also be done on existing homes. The determination of which installation method to use is based on your preferences and the needs of the home itself. We go over all of this in the consultation to make sure you make the best choice for your situation.
