Windows services in St. Louis
Most of the windows we replace across Greater St. Louis are original to the house or a first replacement that has failed at the seals. South County is mid-century ranches through Affton, Mehlville and Oakville — simple pitches, long runs. The city neighbourhoods around Tower Grove and The Hill are brick with parapet walls and low-slope rear additions, which is a different roof entirely. West County runs to larger, newer homes with complex rooflines. Straight-line wind and hail come through most summers, and the temperature swing between seasons is wide enough to work materials hard — expansion and contraction opens seams and fasteners over time. A window that has lost its seal shows it first as condensation between the panes, and no amount of caulk brings that back.
Full-Frame Replacement
When the frame itself has failed, replacing the insert alone just hides the problem.
Insert Replacement
Where the existing frame is sound, an insert is faster, cheaper and less disruptive.
Styles
Double-hung, slider, casement, bay and bow, and fixed picture windows.
How a windows job runs
-
In-home assessment
Every opening measured individually, and the frames checked for damage and water intrusion before anything is quoted.
-
Product selection
Style and glass package chosen against the house and what you want it to do — not one specification applied to every window in it.
-
Careful removal
Old units out, and the wall around each opening checked for the hidden moisture or rot that only shows up once it is open.
-
Precision installation
Levelled, shimmed, flashed and sealed with low-expansion foam, then tested for operation before the crew moves to the next one.

Common questions
Will new windows make a difference in St. Louis winters?
Going from single pane to a modern double-pane unit is a real difference you will feel in a cold snap. Replacing a ten-year-old double-pane with a new one is not — we will tell you which of those you have.
Will new windows actually cut my bills?
They help, and how much depends on what you have now. Single-pane to modern double-pane is a real difference; a ten-year-old double-pane to a new one is not.
Can I get a window repaired instead of replaced?
Sometimes. Worn weatherstripping and a broken latch are repairs. Fog between the panes, rot in the frame or daylight around the edges are not — at that point the unit has failed and a repair only buys a season.
What works in an older home?
A lot of the housing stock here predates 1970, and double-hung units in vinyl or wood-clad fit those openings without rebuilding the wall. Where the frame itself has gone, full-frame replacement is the honest answer.
How long does it take?
One to two hours per window. A whole house of ten to fifteen is two to three days, and we leave each room finished rather than opening every opening at once.
Can I do just a few windows?
Yes. We will match the new units to the existing ones as closely as the product line allows, and tell you where the match will be visible.
What is the difference between an insert and a full-frame replacement?
An insert fits inside the existing frame — quicker, cheaper, and only right when that frame is sound. Full-frame takes it back to the opening and is what you need when the frame is the thing that failed.
