Door Installation in St. Charles MO
Professional door installation for St. Charles County homeowners — entry doors, interior doors, storm doors, and patio doors. Properly hung, plumb, and weathertight the first time.
Door Installation Services in St. Charles
St. Charles County's housing stock spans from 19th-century homes in Old Town St. Charles — where original door openings are rarely square or standard-sized — to modern construction in Cottleville and Wentzville with factory-spec rough openings. We assess every opening before installation and address framing issues before hanging the door, not after.
Entry Door Installation
Prehung entry door installation including frame, threshold, weatherstripping, and hardware. We ensure a weathertight fit that holds up to St. Charles County's cold winters and humid summers.
Interior Door Installation
Interior prehung door installation for new openings or replacement of existing doors. We match door heights and profiles in older St. Charles homes where non-standard sizing is common.
Storm Door Installation
Full-view, ventilating, and retractable screen storm doors installed over existing entry doors. Proper installation prevents the frame racking that causes premature hardware failure.
Patio Door Installation
Sliding and French patio door installation. We address the framing, threshold, and weathersealing requirements that are often overlooked in DIY installations.
Barn Door Installation
Sliding barn door hardware and door panel installation for interior applications. We ensure proper wall blocking and header support for smooth, long-lasting operation.
Historic Door Restoration
Old Town St. Charles homes often have original wood doors worth preserving. We repair, re-hang, and weatherstrip historic doors rather than replacing them when structurally sound.
What Makes a Proper Door Installation
A door that's installed out of plumb or out of square will bind, stick, and fail to latch properly — often within the first year. In St. Charles County's newer homes in Cottleville and Wentzville, rough openings are typically standard and square. In older homes near Old Town and the Missouri River corridor, settling can throw openings significantly out of alignment.
We check every rough opening for plumb, level, and square before installing any door. If the opening has settled, we shim and adjust it before setting the door — not after. This is the step most DIY and budget installations skip, and it's why those doors start sticking within a season.
For exterior doors, we also ensure the threshold is properly sealed and the door is weathertight before we leave. Missouri's cold winters make a properly sealed entry door essential for both comfort and energy efficiency.
Check Rough Opening
Verify plumb, level, and square. Adjust framing or shim as needed before door installation.
Set the Door Unit
Install the prehung door unit with proper shimming at hinges and latch side for long-term alignment.

Fasten through shims into framing. Adjust hinge and strike positions for smooth operation.
Weatherseal & Finish
Install threshold, weatherstripping, and door sweep. Caulk exterior perimeter. Install hardware.
