CWS Impact Garage Doors Nationwide

CWS Impact Garage Doors: The San Francisco Owner’s Guide

CWS impact garage doors in San Francisco typically cost $4,200 to $8,900 installed, depending on the model series, size, and what’s already in the opening. We stock CWS-compatible hardware, springs, panels, tracks, and weatherseal on our trucks, and we can usually get a full door ordered and installed within 2 to 3 weeks. Most San Francisco homeowners discover they need us when a panel won’t sit square, a spring lets go in the middle of the night, or a salt-air-corroded roller finally gives up and the door starts grinding against the track.

We’re an independent service provider, not affiliated with CWS. What that means for you: we replace and repair CWS impact doors because they’re well built, and we know their quirks. We also work with PGT, CGI, and ES Windows products when the job calls for something different.

Which CWS Models This Applies To

CWS impact garage doors come in several series, and the parts are not always interchangeable between them. The most common lines we service in San Francisco are the CWS 3000 series (aluminum frame, insulated core, good wind ratings for bay-facing homes) and the CWS 5000 series (heavier gauge, built for larger openings and higher design pressures). The quickest way to match a part is to check the sticker on the inside of the door edge near the bottom panel. It will list the model number, manufacture date, and a serial number. If that sticker is gone, we measure the panel thickness, the track gauge, and the spring wire diameter to identify what belongs in the opening.

Here’s the compatibility gotcha we see all the time: CWS doors built before 2015 often used a narrower track profile than current production. That means a new panel from a 2024 CWS catalog will hang in the opening, but it won’t ride smoothly on 2012 rails without a track upgrade. We flag this before quoting, not after the panels show up.

OEM versus aftermarket matters less for CWS than for some other brands. The springs, hinges, and rollers are standard industry sizes once you know the door weight and cycle rating. We stock OEM CWS hardware when originality matters (warranty claims, HOA requirements) and quality aftermarket equivalents when it doesn’t, which keeps cost down without cutting corners. Either way, you get the price in writing before any parts are ordered.

Signs Your CWS Impact Garage Doors Are Failing

• The door is heavy to lift by hand. Impact doors are heavier than standard doors by design, but a properly balanced door should still lift with moderate effort. If it feels like dead weight, one or both extension springs have lost tension or snapped. This is a safety issue, not a nuisance.
• Loud pop, then the door won’t move. That’s a torsion spring failure. CWS impact doors use high-cycle springs rated for 10,000 to 25,000 cycles, but salt air in Richmond and Sunset District garages will corrode spring wire faster than inland. When it pops, the door is pinned under tension and should not be forced.
• The door shudders or sticks partway up. Usually a bent track or a broken roller. We see this on older CWS installs where the original builder shimmed the track instead of anchoring it properly to the frame. San Francisco garages built into hillsides have more lateral movement than flat-lot construction, which amplifies these problems.
• Visible rust lines or bubbling on the lower panel. The bottom panel sits closest to damp concrete and fog-wet driveways. CWS applies a marine-grade finish, but ten years of Pacific air will eventually find a scratch. Once the aluminum starts corroding under the powder coat, the panel loses structural integrity and won’t hold its wind rating.
• Gaps of daylight around the door edges. The weatherseal and bottom rubber stop sand, fog moisture, and rodents from getting in. When the seal hardens and shrinks (common in uninsulated garages that bake in afternoon sun), you’ll see light before you feel the draft. This is the cheapest fix on the list and the one most homeowners put off too long.

Replacement Cost & What’s Included

Here’s what we quote in San Francisco, line by line, before any work starts:

• Single torsion spring replacement: $190 – $340 installed
• Roller replacement (set of 10 – 12): $140 – $260 installed
• Track realignment with new hardware: $220 – $480
• Bottom weatherseal and side seals: $110 – $220
• Single panel replacement (CWS 3000 series, standard width): $700 – $1,400
• Full CWS impact door replacement: $4,200 – $8,900 installed

What drives the range: door width (double-bay doors push toward the top of that range), panel design (flush versus raised), wind-load requirements for exposed lots near Ocean Beach or Twin Peaks, and whether the tracks need to be rehung. Every quote includes haul-away of the old door, all hardware, and labor. There’s no add-on line item that appears at the door.

The written price goes on paper before we order the first part. The work is covered under our 365-Day Done Right Promise. If the repair fails within a year, we come back at no charge. That’s a full year, no labor exclusions, in writing.

DIY or Call Us?

You can safely replace the weatherseal yourself if you have a utility knife and patience. You can also tighten loose track bolts and clean the photo-eye sensors. Those are homeowner-level jobs.

The torsion springs are a different story. CWS impact doors run heavier springs than standard residential doors, and the stored energy in a wound torsion spring is enough to cause serious injury or worse. Do not attempt to remove, adjust, or rewind torsion springs without proper winding bars and training. Even experienced techs treat a CWS spring job with respect. It’s the one repair where the money is cheaper than the hospital visit.

For everything else, a misdiagnosis costs more than a service call. We see it regularly: someone replaces the opener motor when the real problem is a failing spring, or swaps rollers without noticing the track has pulled 3/8″ off the frame. If you’re not sure what’s wrong, call (831) 273-7126. We’ll tell you over the phone whether it’s worth a visit, and the estimate is free.
