1. Arrive at Your Home
Our installers and carpenters arrive as scheduled in one of our self-contained shops on wheels. Our professional trucks carry all of our tools, materials, and supplies to make your window and door installation a success. In many cases, much of our work can be done in our self-contained trucks (instead of your living room) that are outfitted with a trim saw, dust collection system, and battery feed power supply. This virtually eliminates sawdust and allows for a much cleaner and safer work environment.

2. Air and Water Tight Installation
Our installers and carpenters are specially trained to keep moisture and air from entering around your new windows and doors. This means that on most installations we can create a waterproof seal around window and door openings utilizing self-sealing adhesive membranes. These membranes work with the home's moisture barrier to help weatherproof your new windows.

3. End of Day Cleanup
At the end of every day as well as the end of the job, our personnel clean the entire work area, ensuring the area is free of nails or any other materials that may risk injury to children, pets, or car tires.

4. Finishing
Due to the fact that we are one of the Western New York's leading siding companies, we are able to handle any siding and trim issues, which may occur during a window/door installation. For an additional charge we can stain or paint the exterior of your window trim.

Next to insulation, energy efficient windows and doors can be one of the best investments you can make in your home. Energy efficient windows and doors can dramatically lower your energy bills and unlike insulation, you can actually see and enjoy new windows and doors.
