Window Installation Process
Precision measurement, expert installation, and a lifetime workmanship guarantee

A high-quality replacement window is only as good as its installation. Even the best triple-pane krypton window will underperform if it is improperly measured, poorly insulated, or inadequately flashed against water infiltration. At Suburban Construction, we have refined our installation process over nearly four decades to eliminate every source of potential failure — from the first measurement to the final cleanup.
Our installation crews are experienced full-time installers. They install windows every day, and they take personal pride in the quality of every installation. We stand behind that work with a lifetime workmanship guarantee — if anything related to the installation itself ever fails, we come back and fix it at no cost to you.





Our Step-by-Step Process
Free In-Home Estimate & Measurement
We measure each opening, assess existing frames, and discuss your goals. No charge, no obligation.
Custom Order
We place a custom order based on precise field measurements. Every window is made to order — not pulled from generic inventory.
Scheduling & Preparation
We schedule installation at your convenience. You clear space around each opening; we bring all tools and materials.
Removal of Old Windows
We carefully remove existing windows, minimizing disturbance to surrounding trim and siding. Old windows go directly into our disposal trailer.
New Window Installation
Each window is shimmed level and plumb, fastened securely, flashed, and insulated. Tested for proper operation before moving on.
Trim, Caulk & Final Seal
We reinstall or replace interior and exterior trim, apply exterior caulk at all perimeter joints, and perform a final inspection.
Cleanup & Walkthrough
We vacuum sills, wipe glass, and clean up all debris. We walk you through each new window before we leave.

Lifetime Workmanship Guarantee
We back every window installation with a lifetime workmanship guarantee. If any aspect of the installation itself — flashing, trim, insulation, sealing — ever causes a problem, we come back and make it right. Combined with the manufacturer's warranty on the window itself, you're fully protected.
