Fast, Reliable ADU Work Across Denver
When your ADU’s garage door fails, you want someone who knows Denver’s rhythms: the Chinook wind that swings the temperature 50 degrees between breakfast and dinner, the June hailstorm that turns a quiet block in Harvey Park into a line of dented doors, the 1920s bungalow in Barnum with an opening too narrow for any modern panel. We answer calls on the first ring at (970) 725-6025 for our Garage Door in Denver service, and we carry the torsion springs, seals, and panels Denver’s older ADUs actually need. You’ll get a named technician, a written price before any work starts, and a repair that holds up through the next freeze-thaw cycle.
Why Haven Is Denver’s Preferred ADU Company
Denver homeowners keep our number because we treat their ADU doors the way the building itself was treated when it went up: with respect for how the structure was framed and what the altitude does to every component. The Haven Standard means the same five clauses govern every visit: the price in writing before work starts, a real arrival window with a named technician, licensed and insured crews whose license number sits on the page, photographic evidence of what we found, and no upsell at the door. That matters when your ADU sits in an alley off Federal Boulevard and the nearest supply house is twenty minutes through traffic.
Our ADU team serves ADU in Denver with the same published standard whether the job is a spring replacement in Sunnyside or a full door retrofit in Park Hill. Alan Brecker leads the work, and every quote includes a line-item range and a photo report, so you see exactly what failed before you agree to fix it. If something isn’t done right, our 365-Day Done Right Promise means we come back and make it right, no argument, no requote.
Our ADU Services in Denver
Torsion Spring Replacement
Torsion spring replacement for Denver ADU doors typically runs $180-$340. The Chinook cycle is brutal on springs: a hard overnight freeze contracts the steel, then a 55-degree warm-up expands it, and the spring cracks. Older bungalow ADUs often run springs rated for 10,000 cycles, which is several years of Denver weather, not decades. We replace with high-cycle springs and balance the door before leaving.
Panel Replacement (Hail Damage)
Hail panel replacement on Denver ADU doors runs $250-$500 per panel, depending on gauge and finish. After a storm track rolls down the I-70 corridor, we see entire alleys behind Barnum and Westwood where every south-facing door is pocked. If the door is older or the foam core is exposed, full replacement is often cheaper over the next five years. We’ll give you both numbers and recommend the route that makes sense for your ADU.
New Door Installation (Sectional, Retrofit)
New sectional door installation for a Denver ADU runs $700-$2,200, including removal of the old door, reframing if needed, and a weather seal rated for the altitude. Many legacy ADU doors are original one-piece units or early sectional models that no longer hold a seal. A Clopay 16×7 with an R-value of 9 is our most common retrofit, but Raynor and LiftMaster doors are equally available depending on finish and hardware preference.
Track Realignment and Roller Replacement
Track realignment on Denver ADU doors runs $120-$240, and roller replacement runs $110-$220. Old detached structures settle. Alley aprons crack and heave with the frost, tilting the track enough to chew rollers. We check the full run and replace rollers with nylon bearings so the door doesn’t rattle every time an RTD bus idles at the corner.

AfterTrusted Brands We Service in Denver
We service and install doors and openers from Raynor, LiftMaster, Chamberlain, and Genie, and we stock Denver-specific parts: high-cycle torsion springs, UV-resistant bottom seals, and 16×7 replacement panels. When a hail storm hits, Denver inventory depletes fast. Keeping a local stock means a dented ADU door in Athmar Park doesn’t wait two weeks on a freight truck.
Common ADU Problems We See in Denver Homes
- Thermal fatigue from Chinook swings snapping extension springs. A 50-degree warmup after a hard freeze is a stress test on old steel. Springs on pre-1940 ADUs often fail in late February and early March, right when you most need the door to close.
- Narrow 8- to 9-foot alley openings preventing a modern sectional door from fitting. Many 1920s and 1930s detached ADU garages were framed for a one-piece door. Before a new sectional goes in, the header and side jambs usually need reframing.
- High-UV exposure at 5,280 feet drying out rubber bottom seals and vinyl weatherstripping. UV runs roughly 25% stronger up here. Seals crack in two to three years, letting snowmelt and hail debris seep under the door and into the ADU.
- Freeze-thaw bonding and tearing bottom seals from concrete aprons. Water refreezes overnight, glues the seal to the slab, and tears it when the door opens. This repeats dozens of times each winter until the seal gives out entirely.

How Denver’s Climate Changes the ADU Door Math
Here’s what makes Denver different, and it’s not a marketing line. The city sits in hail alley, where summer thunderstorms take fifteen minutes to turn a quiet afternoon in Harvey Park into a claiming event. Chinook winds swing temperatures 50-plus degrees within hours, and the freeze-thaw cycle runs on a near-daily schedule from November through March. That combination means your ADU door doesn’t wear out gradually: it fails in bursts. Springs snap. Seals tear. Panels dent. And when hail hits the I-70 corridor, every door on the street fails at once. Denver shops that pre-stock panels and maintain direct insurer billing turn those weeks into their busiest days of the year. We’re one of them, and we also handle Gate Repair in Denver.
We pulled up to a 1930s bungalow near Barnum where the detached ADU’s original one-piece door had sagged so far the track alignment was chewing rollers every few weeks. The torsion spring had long since lost its rated cycles, and the wood jamb was too narrow for a standard sectional door. We reframed the opening, swapped in a high-cycle torsion spring and a 16×7 Clopay steel door with an R-value of 9, then added a reinforced bottom weather seal. Now it locks out the Chinook wind and the hail dents are someone else’s problem.
If your ADU door is original to a pre-war structure, or if the last repair predates the last severe hail event, the repair-vs-retrofit question is worth answering honestly. A door past its spring rating and losing its seal on a south-facing alley exposure is a replacement candidate, not a patch job. We’ll inspect, photograph, and give you both numbers in writing.

FAQs - ADU in Denver
Chinook winds create rapid temperature swings that expand and contract the steel in torsion springs, accelerating fatigue cracking and snap failure. Late winter and early spring are peak failure season in Denver. High-cycle springs with a rating of 25,000 cycles or more typically outlast standard springs by two to three years under these conditions. Call (970) 725-6025 for an exact spring quote.
Usually yes, but the header and side jambs must be reframed first. Many Denver bungalows in Park Hill, Berkeley, and Sunnyside have alley-facing ADU garages framed for original one-piece doors. We open the wall, rework the framing to carry the sectional track load, and install a door sized to the new opening. Expect $700-$2,200 depending on framing scope and door spec.
If more than two panels are dented or the foam core is exposed, replacement is typically the better value. Panel replacement runs $250-$500 per panel, but a full new sectional door starts at $700 and eliminates the structural compromises of piecing panels together. We’ll document the damage for your insurer and provide both written options. Call (970) 725-6025 and we’ll assess it the same day.
The opener is fighting a door that’s out of balance. Denver’s freeze-thaw cycles shift the track alignment and fatigue the springs, so the door gets heavier at the bottom of its travel. The opener then labors and burns out. We rebalance the door and realign the track, which usually costs $120-$240, far less than another opener replacement.
The fix is a reinforced bottom weather seal with a higher UV rating and a profile that doesn’t bond to wet concrete. Denver’s altitude means standard seals harden and crack in two years. We install a seal rated for the UV load at 5,280 feet and adjust the door’s down-force so it doesn’t crush the seal into the slab. A replacement seal runs $110-$220 installed.
