You get a price before we start. It does not change when the truck arrives.
The Servo Garage Doors Ontario Guarantee
When Marcus Deller started Servo Garage Doors Ontario in 2015, he wrote down one rule before anything else: the customer sees the failed part before anyone quotes a replacement. That rule became the foundation for everything we stand behind today. Our guarantee is not a slogan on a truck. It’s a 365-Day Done Right Promise backed by The Haven Standard, a written price before any work starts, and a documented photo record on every visit. If we install a spring, a panel, or an opener in your Ontario home and it’s not right, we make it right. That’s the whole promise, stated plainly, no fine print required.
What’s Covered
Every job we complete in Ontario carries specific commitments, each one written into The Haven Standard we operate under. Here’s what that means when our truck pulls up to your home.
- Workmanship on every repair and installation. If our labor doesn’t hold up, we return and fix it under the 365-Day Done Right Promise, no cost to you.
- Parts handled with documentation, not just replaced. Clause 4 of The Haven Standard is why the technician photographs the failed part before quoting a replacement, so you see exactly what broke.
- Cleanup and job-site care. We leave your Ontario garage the way we found it, or cleaner, with old parts and debris hauled away unless you ask to keep them.
- On-time arrival with a named technician. When you book, you get a name and an on-the-way text, not a four-hour window and a stranger at the door.
- Honest pricing agreed before work begins. Clause 1 of The Haven Standard means a flat, written price and written scope are delivered before any work starts. The number you approve is the number you pay.
- A documented photo record on every visit. After the work is done, you receive evidence of what was found and what was done. That record traces back to the founding rule Marcus built Servo on in 2015.
Our Satisfaction Promise

If something isn’t right after we leave, call us. A real person answers, 24/7, including holidays. You won’t explain the problem to a recording or wait for a callback window. We’ll schedule the return visit, send a named technician, and make the repair right under the 365-Day Done Right Promise. That promise is not a handshake. It’s backed by The Haven Standard and a terms page you can read before you ever pick up the phone. In Ontario, where spring heat and Santa Ana winds put real stress on torsion springs and opener logic boards, we’ve stood behind thousands of jobs since 2015. We’re not going to change that standard on yours. Bring us the problem. We’ll bring the documentation and the fix.

AfterLicensed & Insured Backing
A guarantee is only as good as the company standing behind it. Servo Garage Doors Ontario is independently owned and operated under The Haven Standard. That’s not a franchise arrangement. It means Marcus Deller, the owner, holds his own license and insurance for this local business, and The Haven Standard contributes the documentation system he agrees to work to on every job. If a technician is on your Ontario property and something goes wrong, you are dealing with a licensed, insured local operator, not a faceless network. When we say “we stand behind our work,” the license and insurance are the actual backing behind that sentence. Ask to see them. On our side, that request is never a problem.
What the Warranty Looks Like in Practice

A homeowner in the Creekside neighborhood of Ontario called us about a garage door that wouldn’t stay open. The torsion spring measured at 0.25-inch wire diameter and showed a clean break at the coil. We showed her the photograph before we quoted the replacement. The written price covered the new spring, labor, and a follow-up inspection if anything felt off within the year. That’s how every job in Ontario works. We don’t do verbal estimates. We don’t do “call for a quote.” You get the flat written number before the work starts, and you get the documented photo record when the work is done.
We service all eight major brands: LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor. Whether your opener is a chain-drive LiftMaster or a belt-drive Chamberlain, the guarantee works the same way: if it’s not done right, we make it right. The manufacturer’s warranty on parts is separate from our workmanship promise. Our promise covers what we do. The manufacturer covers what they made. We’ll explain both clearly so you know exactly who stands behind what.
