Interior & Exterior Door Installation
Detailed Description
A Door That Sticks, Drags, or Won’t Latch in Your Toronto & GTA Home Is a Daily Frustration That’s Completely Fixable
Doors that stick in summer humidity, won’t stay latched, drag along the floor, or swing open on their own are among the most common complaints in Toronto & GTA homes — and they’re almost always installation or adjustment issues rather than inherent product problems. A door hung even slightly out of plumb will behave exactly this way. In Toronto & GTA’s climate, where seasonal humidity variation causes wood to expand and contract predictably, a door that was borderline on installation day becomes a problem door by August.
At CNG Contracting, door installation in Toronto & GTA is done to a standard where the door operates correctly regardless of season. Plumb, level, and correctly shimmed — with hardware aligned so the latch engages on the first try and the door holds where you leave it. For exterior doors, proper weatherstripping and threshold seal are part of the scope, not an afterthought.
What Proper Door Installation Requires in Toronto & GTA
- Opening Preparation: The rough opening in your Toronto & GTA home must be plumb, square, and the correct size for the door unit being installed. We assess and correct before hanging.
- Shimming and Fastening: Proper shimming at hinge and latch locations ensures the door frame is secure, plumb, and correctly sized to the door — preventing sticking and alignment issues.
- Hardware Alignment: Strike plate and latch alignment so the door latches on contact without force — one of the most common failures in quickly-hung doors across Toronto & GTA homes.
- Exterior Door Sealing: For exterior doors in Toronto & GTA, weatherstripping condition, threshold seal, and caulking around the exterior casing are included — because an exterior door that doesn’t seal is an energy loss and a water infiltration risk.

Frequently Asked — Door Installation in Toronto & GTA
Can you install a door in an existing opening in my Toronto & GTA home?
Yes — both new rough openings and replacement of existing doors in current frames. For replacements, we assess whether the existing frame is in suitable condition for a new door unit or requires replacement as well.
Why does my Toronto & GTA home door stick more in summer than winter?
Wood doors and frames expand with summer humidity and contract in Toronto & GTA’s dry winters. A door that sticks seasonally was either hung without enough clearance or in an opening that isn’t plumb. Proper installation accounts for seasonal movement — we assess and advise during the visit.

Why is a Technical Visit necessary?
A door is only as good as its frame. Installing a square door into a shifted or out-of-square frame leads to gaps, drafts, and security vulnerabilities. Our Interior & Exterior Door Installation assessment measures the rough opening, checks for subfloor rot (especially for exterior doors), and determines if you need a simple slab replacement or a full pre-hung system for a weather-tight seal.
