For property managers
Garage doors across a portfolio, handled by Garry and Damaris, your installation team.
Most garage door companies are set up for homeowners — one door, one emergency, one card payment at the end. Managing property is a different job. You need someone who picks up, who knows which building you mean, and who bills you properly afterwards.
Work directly with Garry and Damaris
Garry and Damaris are Square One Garage Doors’ official installers, working together as one two-person crew. We handle the inspection, explain your options, complete the work, and test the system before leaving.
One account across your properties
Doors at different addresses go on one account with one contact, so you are not opening a new relationship every time a different building needs something.
Work is invoiced, not collected at the door
Repairs are quoted before the work, invoiced after it, and paid on terms — not a card reader handed to whoever happens to be on site.
You get the specifics, in writing
A quote names the actual part or door model rather than a category, so you can see what changed and why the price is what it is. Photos of completed work on request.
Insurance, on paper
General liability of $1,000,000 per occurrence and $2,000,000 aggregate is in force with Hiscox, under DareliM & GnukuM LLC — the legal entity behind the Square One trade name. A certificate of insurance naming your company as additional insured is issued on request. Vendor paperwork is a normal part of the job, not an obstacle to it.
What we handle
Broken springs, cables and rollers · doors that will not close or reverse · opener replacement and repair · full door replacement · and the tune-ups that stop the first three from happening as often.
Starting a conversation
The fastest way is to call (303) 994-0375 and describe one door that is giving you trouble. If it goes well, the rest of the portfolio is a much easier conversation than a pitch is.
Prefer email? Send the details through the contact form and include the property address and what the door is doing.
Questions managers actually ask
Common questions
How many properties do you currently service?
Square One is a new business, and pretending otherwise would be the wrong way to start. You work directly with Garry and Damaris, our installation team. If you want to start with one property and see how it goes before giving us more, that is the sensible way to do it and we would suggest it ourselves.
What areas do you cover?
Denver, Aurora, Centennial, Parker, Englewood, Littleton, Highlands Ranch, Lone Tree, Castle Rock, Monument and Colorado Springs. Colorado Springs is a real drive from the Denver side, so scheduling there is planned rather than same-day.
Can you handle multiple doors at one property?
Yes. A row of doors at one building is quoted as one job rather than as separate visits, and the pricing reflects that we are already on site — the second door does not cost what the first one did.
Do you do emergency call-outs?
A door that will not close is a security problem, not a maintenance item, and it gets treated that way. Garry and Damaris work together as one crew, so availability depends on the work already scheduled. Call us to confirm the soonest appointment we can offer.
What do you need to set up an account?
A contact, a billing address, and the list of properties. If your process requires vendor paperwork before work can be scheduled, send it over and it comes back completed — that is a normal request and it does not slow anything down.
How do you price repairs?
A service call covers the visit and the diagnosis, and it is credited against the work if you go ahead. Repairs are quoted before anything is done. Nothing gets fixed on the assumption you would have said yes.
