Window Product Options
Decker commonly installs ProVia replacement windows, including the ProVia Endure series. We can also source other major window products through ABC Supply when another option is a better fit for the opening, performance goals, style, or budget.
What New Windows Can Improve
Comfort
A properly installed window can reduce drafts and may improve comfort and efficiency, depending on product and installation.
Operation
New units open, close, and lock as intended.
Exterior Appearance
Updated windows and trim refresh how the home looks from the street.
Protection Around Window Openings
Flashing, sealing, and repaired trim help protect the opening from water.
The Opening Matters as Much as the Window
- 1.Confirm window type, size, operation, and finish.
- 2.Protect interior and exterior adjacent surfaces.
- 3.Remove the existing unit as required by the installation method.
- 4.Inspect the opening for visible damage or deterioration.
- 5.Complete included wood-rot or trim repair.
- 6.Install, level, fasten, flash, and seal the replacement window.
- 7.Install or repair interior/exterior trim where included.
- 8.Complete caulking, touch-up work, and cleanup.
Larger wood-rot, siding, trim, or surrounding carpentry repairs are defined separately when they extend beyond normal window installation. When trim restoration calls for repainting, exterior painting can be included in the scope.
