Replacement Windows Installed Right
New windows can make your home more comfortable, quieter, and brighter, but only when they are installed correctly. Baser Construction helps homeowners with window installation in Franklin County and window installation in St. Louis County choose replacement windows that suit their homes, then installs them square, sealed, and properly flashed.
Drafty Rooms: Air leaking around old sashes and frames makes rooms uncomfortable. New, properly sealed windows keep drafts out.
Fogged Glass: Condensation trapped between panes means the seal has failed and the window has lost much of its insulating value.
Sticking or Broken Windows: Sashes that will not open, stay up, or lock are frustrating and a safety concern. Replacement solves the problem for good.
Rot Around the Frame: Soft wood or water stains around a window point to moisture getting in. We repair the opening before the new window goes in.
Why Choose Baser Construction?
A great window installed poorly will still leak. Because our crew also does framing, roofing, and siding, we can fix problems in the opening itself and tie the new window cleanly into your exterior.
Help Choosing Windows: We help you pick styles and materials that complement your home and fit your budget, without pressure.
Openings Done Right: Damaged framing or trim around a window is repaired, not hidden, so the new window performs as it should.
Exterior Tie-In: New windows are flashed and sealed to work with your siding, so water drains away from the wall instead of into it.
