Window Installation & Replacement FAQ for St. Louis Homeowners

How often should St. Louis homeowners get window installation & replacement?
Given St. Louis's severe tornado and hail risk in spring and fall along i-44 and i-70 corridors, most homeowners benefit from window installation & replacement at least once a year. Ice storm branch and gutter damage (Dec–Feb) often makes spring or fall the optimal time to schedule service.
What home types in St. Louis most need window installation & replacement?
Red brick bungalows and two-stories throughout St. Louis County and Victorian homes in Lafayette Square and Compton Heights are the most common home types in St. Louis and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
Replace vs. repair — how do I decide?
Repair if: single broken pane, failed hardware on an otherwise sound window, or wood window with good bones. Replace if: failed seal (fogged double-pane), significant rot or damage, single-pane glass, or the window is over 20 years old.
What's the difference between insert and full-frame replacement?
Insert (pocket) replacement fits inside the existing frame — less invasive and less expensive. Full-frame removes everything down to the rough opening — necessary when frames are rotten or damaged, and allows different sizes.
What window frame material is best?
Vinyl: most affordable, low maintenance, good insulation. Fiberglass: best performance, most durable, higher cost. Wood: beautiful but requires maintenance. Composite: combines wood interior with durable exterior.
Are there tax credits for new windows?
Yes. The Energy Efficient Home Improvement Credit provides 30% (up to $600 per year) for qualifying Energy Star windows. Many utilities also offer additional rebates.
