You get a price before we start. It does not change when the truck arrives.
The Servo Garage Doors Littleton Guarantee
We stand behind every door we touch in Littleton with something more useful than a handshake: a written record of what we found, what we quoted, and what we did. Since 2015, Servo Garage Doors Littleton has put a flat, written price in front of every homeowner before work starts, not after. If the work isn’t right, our 365-Day Done Right Promise means we come back and make it right, no debate, no restocking fee, no “that’s not covered” routine. The guarantee isn’t a sticker on the van. It’s Clause 1 of The Haven Standard, the operating agreement we’ve worked under since the day the doors opened.
What’s Covered
- Written price before work starts. Every job in Littleton gets a flat price and a written scope delivered before a tool comes off the truck, per Clause 1 of The Haven Standard.
- 365-Day Done Right Promise. If a repair we made doesn’t hold up, we return and fix it properly within a year of the original service date.
- Documented photo record on every visit. You receive photos of the failed part before we quote a replacement, and photos of the completed work when we leave.
- All eight major brands serviced. LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor; vendor warranty claims are filed correctly the first time.
- Cleanup included, no exceptions. Broken springs, old rollers, cable fragments, and packaging leave with us, not in your garage.
- Named technician on every call. When you book, you know who’s coming. Background-checked, uniformed, and accountable to the standard, not a subcontractor.
- Free second opinion on any written estimate. Bring us another company’s written quote and we’ll review it line by line, no obligation and no coupon required.
Our Satisfaction Promise

If a Littleton homeowner isn’t satisfied with work we’ve done, the process is simple: you call, you tell us what’s wrong, and we schedule the return visit. No arbitration, no waiting on hold through three departments. Marcus Deller, owner of Servo Garage Doors Littleton, is the name on the standard, and he’s the one who makes the call on how it gets fixed. Most issues are resolved on the first return trip, because the photo record from your original visit shows us exactly what the door looked like when we left. If we missed something, the 365-Day Done Right Promise covers the correction at no charge. This isn’t a “we’ll try” policy. It’s a written commitment that traces back to the founding rule Servo was built on in 2015: the customer sees the failed part before anyone quotes a replacement, and the customer sees the finished work before anyone asks for payment. If you’re not happy, we’re not done.
Before
AfterLicensed & Insured Backing
A guarantee is only as strong as the company behind it, and the company behind Servo Garage Doors Littleton is independently owned and operated, state-licensed, and insured. That matters in a real way when a torsion spring lets go at 7 a.m. on a Monday and your car is trapped in the garage. A licensed company answers to the state. An insured company answers for the unlikely, the accidental, the what-if that nobody plans for. When Marcus Deller sends a technician to a home in Ken Caryl, Sterling Ranch, or Roxborough Park, that technician carries the company’s license and insurance on every job, not just the ones where a homeowner remembers to ask. The documentation system, the photo record, the written scope; all of it is backed by a business that has operated under The Haven Standard since 2015. The paperwork isn’t the guarantee. The guarantee is what the paperwork proves.
What The Haven Standard Actually Means

We don’t expect Littleton homeowners to know what “The Haven Standard” is when they first call us. Here’s the short version: it’s the operating agreement Servo Garage Doors Littleton works under, and it’s written in clauses, not slogans. Clause 1 is the written price before work starts. Clause 4 is the documented photo record on every visit. The 365-Day Done Right Promise is tied to the standard’s terms page, not to a technician’s mood on a Friday afternoon. Marcus Deller owns the business. The Haven Standard is the rulebook he agreed to run it by. When one of our technicians tells you the price won’t change once we start, that’s not a sales pitch; it’s the literal operating procedure. When we photograph the broken torsion spring and show it to you on the truck, that’s not theater; that’s Clause 4 compliance. The standard exists because “trust me” doesn’t hold up in a garage. Evidence does.
Common Questions About Our Guarantee
Does the written price ever change once work starts?
No. The flat, written price and written scope you approve before work begins is the price you pay when the job is done. If we find something unexpected mid-repair, we stop, show you the photo evidence, and get your approval on a new written scope before proceeding. The price is agreed before any work happens, every time. Call (720) 636-7083 if you’d like to talk through how this works before booking.
What does the 365-Day Done Right Promise actually cover?
It covers the workmanship and parts we install. If a repair we made fails within a year of service due to our workmanship or a defective part we supplied, we return and correct it at no charge. Manufacturer warranties on new doors and openers are separate and we file those claims for you. If you’re holding a competing written estimate, we’ll also give you a free second opinion on it; bring the paperwork and we’ll go through it line by line.
Do you photograph the work even if I don’t ask?
Yes. The documented photo record is included on every visit, not as an add-on. You receive photos of what was found before we quote anything, and photos of what was done before we leave. Clause 4 of The Haven Standard makes it non-optional. For a Littleton homeowner, that means you’ll never pay for a replacement part you never saw fail.
What if I’m not satisfied with the work?
You call us and tell us what’s wrong. We schedule the return visit, review the photo record from the original job, and fix it. No arbitration, no fine print, no waiting on hold through three departments. The 365-Day Done Right Promise is the backstop to our workmanship. Call (720) 636-7083 and we’ll make it right; that’s the entire point of the promise.
