Door repair Markham – one number for the house and the business
Markham calls tend to come in two shapes. A homeowner whose front door has started sticking or will not lock, and a facilities manager whose clinic or office entrance has stopped latching and cannot be secured at closing. We run one crew that handles both, which matters more than it sounds – most companies do one or the other and subcontract the rest.
The town also has an unusual amount of newer housing, and that shapes the work. Homes built in the last twenty to thirty years across Cornell, Wismer, Greensborough and Berczy hit their first real door problems around now: builder weatherstripping compressed flat, thresholds dropped, heavy insulated slabs pulling their hinges loose. All of it is repair work, none of it needs a new door.
What we repair in Markham
Front & entry doors
Sagging slabs, failed weatherstripping, doors that stick in summer and rattle in winter, worn hinges and misaligned strikes.
Door frames & jambs
Split jambs, rotted bottoms, frames forced during a break-in, and reinforcement so it does not happen twice.
Sliding & patio doors
Worn rollers, bent or dirty tracks, doors off the rail, broken handles and locks, failed seals letting in water.
Commercial storefronts
Aluminum entrances, pivots, closers, panic bars, electric strikes and mag locks for retail and offices.
Locks & hardware
Lock changes and rekeys, cylinder replacement, handle sets, deadbolts, latches and door hardware of every type.
Glass & panels
Broken glass replacement, board-ups after damage, tempered and safety glass for commercial entrances.
The door faults we are called out for most in Markham
The front door has started letting air in
Builder-grade weatherstripping compresses flat after a decade and the adjustable threshold drops with it. Two inexpensive parts, under an hour, and the draft stops.
A heavy insulated door has sagged
Insulated steel and fibreglass slabs are heavy enough to tear hinge screws out of a soft jamb. We anchor into the structural framing with long screws and shim the hinges back to square.
The deadbolt no longer meets the strike
The frame has shifted. We reposition or deepen the strike and fit a reinforced plate where the jamb has softened, which also makes the door far harder to force.
The garage-to-house door will not self-close
That door is fire-rated and legally has to close and latch on its own. A worn closer or dropped hinge fails that, and we reset or replace the hardware so it complies.
A clinic or office entrance is slamming
A drifted closer, usually over a worn pivot. Common along Highway 7 and Woodbine where entrances cycle constantly. We rebuild the pivot and reset the closer.
The door was forced during a break-in
Priority dispatch. We repair or replace the split jamb, fit new hardware and reinforce the strike and hinge areas so the same door does not fail twice.

How a Markham door repair call works
- You call or send photosWe answer 24/7 on 647-951-3510. A photo of the door and frame usually tells us what parts to load before we leave.
- We arrive and diagnoseSame-day across most of Markham. The technician inspects the door, frame, hinges and hardware and finds the actual cause rather than the symptom.
- You get a fixed priceUpfront, in writing, before anything is touched. No commission, no surprise line items at the end.
- We repair and testMost jobs finish on the first visit. We test the door, check alignment and latching, clean up and leave you with a warranty on the work.
Break-in, or a door that will not lock tonight?
Forced entries, storm damage and failed commercial entrances get priority dispatch 24 hours a day, seven days a week, weekends and holidays included.
Commercial door repair for Markham businesses
The Highway 7, Woodbine and Warden corridor gives Markham a dense commercial base – office campuses, tech and pharma facilities, medical and dental clinics, plazas and restaurants. Those entrances cycle thousands of times a week, and fire-rated openings with panic hardware there are a compliance matter as much as a convenience one.
Commercial work in Markham includes door closer repair, panic bar installation, window replacement, aluminum storefront door repair, accessible push-button openers and scheduled maintenance.
The cheap fix that prevents the expensive one
Two long screws through the strike plate and the top hinge into the framing behind the jamb costs almost nothing and is the single biggest difference between a door that resists a kick and one that does not. Ask us to do it while we are there for anything else.

Markham door repair — frequently asked questions
How fast can you reach Markham?
Most Markham calls are same-day and emergencies get priority dispatch 24/7. Call 647-951-3510 for a real arrival window.
Do you charge for an estimate?
No. Estimates are free and the price is confirmed in writing before any work starts.
My house is only fifteen years old. Why is the door failing?
It is not failing – the wear parts are. Weatherstripping, thresholds and hinge screws are consumables, and fifteen years is exactly when they give out.
Can you fix the fire-rated garage-to-house door?
Yes. That door must self-close and latch on its own. We reset or replace the closer, hinges and latch so it meets the requirement.
Do you cover Unionville and Thornhill too?
Yes, along with Cornell, Milliken, Box Grove, Berczy and the rest of the town.
Can you repair instead of replace?
Usually. Sticking doors, failed latches, worn rollers and drafty seals are almost always repairs, not replacements.
Is the work warrantied?
Yes, on labour and on the parts we supply, written on your invoice.
Which payment methods do you accept?
Cash, debit, e-transfer and all major credit cards. Businesses can be invoiced.
