What failing units actually cost you.

Old single-pane and failed double-pane units are a comfort problem before they are an energy-bill problem: cold drafts along the floor in January, rooms that never cool down in August, condensation trapped between the panes, and sashes that will not stay open. Modern double- or triple-pane units with low-E coatings, argon fill and warm-edge spacers make an immediate, obvious difference in a Kansas City home.

Choosing frames, glass and doors.

We help you weigh frame material, glass package and grille style against what you are actually trying to fix, and we put every option in writing. On the door side, an insulated fiberglass or steel entry door with a proper sill pan and weatherstripping seals far better than the builder-grade unit it replaces, and it is one of the most visible upgrades you can make to the front of the house.

Installed square, sealed and flashed.

A premium window installed badly performs worse than a mid-range window installed correctly. Our crews check the opening for rot and square, set units plumb and level, flash the head and sill properly, insulate the shim space without over-packing it, and finish interior and exterior trim cleanly. Because we are a full Class A general contractor, we can also repair the siding, drywall or wood rot the opening reveals. Call or text (816) 400-9596 for a free window and door estimate.
