Springs, openers, off-track doors and new installations from Thornhill's local garage door team. Licensed, insured and 4.9★ rated.
Thornhill is right next door to our Concord office. For many Thornhill streets we are literally the closest garage door company there is, and it shows in our response times: same-day is standard here, and urgent calls are often handled within a couple of hours.
Most of Thornhill, on both the Vaughan side west of Yonge and the Markham side east of it, went up in the 1970s and 80s. Those established homes are our bread and butter. Heavy old wood doors that tired springs can no longer lift properly. First and second-generation openers overdue for retirement. Owners who want to keep the classic look but are done with sanding and repainting, which is where a wood-look insulated steel door comes in.
We serve the whole community, including Thornhill Woods, Brownridge, German Mills and Royal Orchard, with repairs, replacements and annual tune-ups.
Serving all of Thornhill on both the Vaughan and Markham sides: Thornhill Woods, Brownridge, Uplands, Royal Orchard, German Mills and Grandview.
Often faster than anywhere else we serve, because the office is minutes away. Same-day is standard, and real emergencies get priority immediately.
First we check the springs, because a properly balanced door should feel light by hand no matter what it’s made of. If the wood itself has soaked up years of moisture and gained weight, an insulated steel replacement is lighter, warmer and needs no upkeep, and we can style it to look like the original.
Yes. An annual tune-up catches worn parts before they leave your car stuck in the garage, and it’s particularly worthwhile once a door passes the 15-year mark. Details are on our maintenance page.
“The visit occurred on the same day, just three hours after our first contact! The technician performed the repairs very efficiently and swiftly. He explained what he did and it ended up costing less, as not everything was necessary. Wonderful experience overall.”
“My garage door would not open, so I contacted Summit. Meir arrived on time as he said he would, assessed the situation and gave me three options based on my needs and budget. The workmanship was exceptional. Very happy and satisfied — highly recommend.”
“Their team came to our office in Vaughan and replaced a broken door spring, adjusted the cables and made sure everything was properly tensioned. On time, very professional, clean work environment. Highly recommended!”
