CWS Door Installation: The Los Angeles Owner’s Guide
A CWS door installation in Los Angeles typically runs $350 to $900 for a standard hardware replacement and $1,200 to $3,400 for a full door replacement, depending on the model and what failed. We stock CWS-compatible hardware on our trucks for most 2015-2025 series doors, so a failed part is usually replaced the same day we diagnose it. Most owners discover they have a problem the hard way: the door starts grinding on its track, the lock cylinder stops turning, or the panel catches on the frame and won’t close flush anymore.
Key Takeaways:
- CWS door parts we install most in Los Angeles: rollers, hinges, locksets, weatherstripping, and full door slabs
- Typical installed cost range is $350-$3,400; written price before any work starts
- We’re an independent installer, not affiliated with CWS, but we specify CWS-compatible parts by series, not guesswork
- Same-day repair is standard for common failures; full door swaps take 2-4 hours once the slab is on site
Which CWS Models This Applies To
CWS (Custom Window Systems) builds doors across three lines that show up constantly in Los Angeles homes: the 3400 Series, the 3700 Series, and the 9600 Series. Each has its own hinge geometry, roller specs, and weatherstrip channels. The gotcha is that a 3400 Series hinge will not sit flush on a 3700 door even if the screw pattern looks close at first glance. The mounting plate depth differs by just over 3/16 of an inch, and that’s enough to throw the door out of square.
To identify your door, check the corner of the glass or the edge of the frame for a laser-etched code. On 3400 Series doors it reads CW3400 followed by a four-digit production date. The 3700 and 9600 lines moved the etching to the top hinge leaf on the frame side. If the label is gone, we measure the roller diameter and the hinge mortise depth on site and match from there. For CWS specifically, we recommend OEM hardware over aftermarket equivalents. The aftermarket rollers we’ve tested wear visibly faster on the track profile CWS uses, particularly on west-facing doors that get hammered by afternoon sun in neighborhoods like Sherman Oaks and Westchester.
Signs Your CWS Door Installation Is Failing

- The door scrapes the frame or floor when you push it closed. This usually means a roller bearing has flattened or a hinge leaf has worked loose. On CWS doors it’s most common on the hinge side because the door’s weight sits on the top two hinges when open.
- The deadbolt won’t turn without lifting the handle. This is a classic CWS alignment issue: the strike plate has shifted slightly out of line with the bolt, which happens as the door settles. The fix is a strike plate adjustment, but ignoring it wears out the lock cylinder and eventually the entire lockset.
- You feel a draft or see a sliver of daylight along the bottom. The compression weatherstrip on CWS doors loses its rebound in a few years of LA heat, particularly in valley areas where summer temperatures top 100. The channel design is specific to CWS, so a generic strip won’t seat properly.
- The door is harder to open than it used to be. Rollers that carry the door’s weight on the track lose grease and begin to flat-spot. On 3400 Series doors, this typically shows up after 6-8 years; on the heavier 9600 Series with impact glass, sometimes sooner.
- You hear a metallic pop or creak when the door moves. That’s a hinge pin binding or a cracked roller housing. It won’t resolve itself, and running the door like that accelerates wear on the entire track assembly.

AfterReplacement Cost & What’s Included
Here’s what CWS door installation costs look like across Los Angeles, with our written pricing structure:
| Service | Installed Price Range | What It Includes |
|---|---|---|
| Roller replacement (set of 4) | $350-$500 | OEM-spec rollers, track cleaning, alignment check |
| Hinge or lockset replacement | $250-$450 | Hardware, mortise work, strike plate realignment |
| Full weatherstrip replacement | $200-$350 | All compression channels, threshold cap, corner seals |
| Complete door slab replacement | $1,200-$3,400 | New CWS-compatible slab, hardware transfer or upgrade, frame adjustment, haul-away |
The range depends on two things: which CWS series you have and whether the frame is still square. A 9600 Series impact-rated door costs more to replace than a 3400 because the slab itself is heavier and the glass package is more expensive. In Los Angeles, the other price driver is frame condition. Older wood frames in Silver Lake and Echo Park bungalows sometimes need corrective work before a new slab will sit right, and that labor is part of the written quote. Here’s what we don’t do: we don’t give a verbal estimate and then add line items once the work starts. The measured survey you keep is the same document as the invoice. That’s Haven Clause 1 and Clause 5 working together.
DIY or Call Us?

If your CWS door is grinding, you can safely do two things before calling anyone: check whether the screws on the hinge leaves are still tight, and look at the bottom weatherstrip to see if it’s torn or compressed flat. Those are observations, and they help us diagnose faster. What we don’t recommend is pulling the door off its track. A CWS door panel, especially a 9600 Series with laminated impact glass, weighs more than most homeowners expect. When a panel comes off the track it can drop fast, and a falling door does real damage to people and flooring. The rollers ride on a fixed track profile that requires the door to be tilted at a specific angle during removal; getting it wrong bends the track or the hinge tabs. If the door scrapes, sticks, or won’t latch, call us at (509) 265-6387. We’ll measure, write the price, and get it moving properly, usually same day.
FAQs
Expect 15 to 25 years from the door slab itself, but hardware like rollers, hinges, and weatherstripping has a shorter service life of 6 to 10 years in LA’s climate. The heat and UV exposure, absent the moisture cycling you’d see in other markets, breaks down seals and grease gradually. If you’re in a coastal neighborhood like Playa del Rey or Marina del Rey, salt air will accelerate hinge and lock corrosion on any door line, CWS included. Call (509) 265-6387 if your door is past year eight and starting to act up; we’ll tell you what’s actually worn.
Some CWS door parts can be refurbished, but not many. Rollers can’t be re-greased effectively once the bearing seal fails, hinges that have wallowed out their screw holes can sometimes be repaired with a plate, and a misaligned strike plate is almost always a simple adjustment, not a replacement. Locksets can be rebuilt if the cylinder is intact. Our honest default is replacement with a CWS-compatible part, because rebuilt hardware fails again sooner and the labor to revisit is more than the savings. Bring us the specific symptom and we’ll tell you over the phone which category you’re in before anyone shows up.
A roller or hinge replacement on a CWS door takes 45 to 90 minutes on site. A full door slab replacement runs 2 to 4 hours from start to finish, assuming the frame doesn’t need correction. The catch is lead time on the slab itself: some CWS Series glass packages are built to order, and that can take 1 to 3 weeks. Common sizes we can often source within days. We’ll tell you the schedule in the measured survey before you commit to anything.
Yes. Our Los Angeles service trucks carry CWS-compatible rollers, hinges, weatherstripping, and common lock cylinders for the 3400, 3700, and 9600 Series. For full door slabs, we order to your exact measurements and series specification, which is why the measured survey matters. We also stock compatible hardware for PGT, CGI, and ES Windows doors when a mixed-brand home needs attention in the same visit.
If your CWS door is failing, the next step is a phone call. We answer live, we’ll ask you a few questions about the symptom and the door’s age, and we’ll schedule a measured survey that leaves you with a written price before any work begins. Sonia Raman has been reading CWS rough openings and frame conditions across Los Angeles for close to two decades, and the rule she works by hasn’t changed: measure once, write it down, then measure again.
