Doors That Seal and Operate Correctly

Doors that don't close flush against weatherstripping waste heating and cooling energy, create gaps where insects enter, and compromise security when deadbolts don't align with strike plates. JW Carpentry installs interior and exterior doors throughout Des Moines with precise fit and alignment, addressing framing issues that cause doors to stick, swing open on their own, or leave visible light gaps around the perimeter. The service handles single replacements for one damaged door or multiple upgrades when homeowners want consistent style and improved performance across the entire house.

Installation involves more than hanging a slab—it includes checking the rough opening for square and plumb, shimming the frame so the door operates without binding, and adjusting thresholds so weatherstripping compresses evenly along the bottom edge. Exterior doors require proper sealing to prevent air infiltration and water intrusion, while interior doors need hinge placement that supports the weight without sagging over time.

Door installation starts with measuring the rough opening and checking for level across the threshold and plumb along both sides, because even small deviations cause the door to swing improperly or fail to latch. Exterior doors in Iowa face freeze-thaw cycles that warp frames and crack weatherstripping, so replacement includes upgrading to insulated cores and compression seals that maintain contact even when wood expands in summer humidity. Hinge screws must penetrate framing studs rather than just the jamb trim, and strike plates need to be recessed so the latch bolt engages fully without rattling.

After installation, you'll notice the door closes with consistent resistance from weatherstripping contact, the latch engages without forcing the handle, and there's no light visible around the perimeter when the door is shut. Interior doors swing smoothly and stay in position when opened partially, rather than drifting closed or banging against the stop. Thresholds sit level with flooring transitions so there's no trip hazard, and the gap under the door allows clearance for carpet or rugs without scraping.

The work includes finishing details like casing trim that matches existing molding profiles, door stops positioned to prevent handle damage to walls, and hardware installed at consistent heights so locks and levers align across the home. Framing adjustments might be necessary if the rough opening is oversized or out of square, requiring shims, additional blocking, or trimming the jamb to fit correctly.
