Door Installation Services in O'Fallon

A properly installed door improves security, energy efficiency, and curb appeal. Hero Handyman Pro handles all types of door installations for O'Fallon homeowners — from a single interior door to a full exterior entry replacement.

Interior Doors

Bedroom, bathroom, closet, and hallway door installation and replacement. Many O'Fallon homes built in the 1990s have hollow-core doors that are ready for an upgrade. We hang pre-hung doors or slab doors, ensuring smooth operation and proper clearance for your flooring.

Exterior Doors

Front entry, back door, and side entry replacements. O'Fallon's temperature swings from below zero to 95°F+ mean exterior doors need proper weatherstripping and threshold seals to prevent drafts and moisture intrusion. We install fiberglass, steel, and wood entry doors with proper flashing and caulking.

Storm Doors

Storm doors add an extra layer of protection against O'Fallon's harsh winters and spring storms. We install full-view, ventilating, and security storm doors from leading brands. Proper installation ensures the door closer operates smoothly and the door seals tightly against the frame.

Door Frame Repair

Damaged or rotted door frames compromise security and allow drafts. We repair split jambs, replace rotted sill plates, and reinforce kick-in damage. Frame repair is often more cost-effective than full door replacement and restores proper door function quickly.

Door Adjustments & Repairs

Sticking, dragging, or not latching properly? O'Fallon's seasonal humidity causes wood doors to swell and stick in summer. We plane, adjust hinges, and re-align strike plates to restore smooth operation — often a quick fix that avoids a full replacement.

Sliding & Patio Doors

Sliding glass doors that stick, jump the track, or have broken rollers are a common issue in O'Fallon homes with rear deck access. We repair or replace rollers, tracks, and handles — and can replace the full sliding door unit when needed.
