CWS Door Installation: The Miramar Owner’s Guide
CWS door installation in Miramar typically runs $890 to $2,400 for a complete replacement, depending on whether the opening is standard or impact-rated, and whether the frame needs reframing. We stock CWS-compatible hardware, hinges, and seal kits on our trucks, and most installs are completed in a single day once the measured survey is signed. Most Miramar homeowners discover a CWS door is failing when the sweep drags on the tile, the multipoint lock won’t engage after a humid morning, or they notice daylight between the jamb and the weatherstrip after a northeast storm.
Which CWS Models This Applies To

CWS manufactures several door lines common in South Florida, and the part you need depends on the series stamped on the hinge edge or the top of the frame. We regularly work with the CWS 3750 and 3770 impact-rated entry systems, the CWS 5400 sliding patio door, and the CWS 9800 multi-slide, all of which have different jamb depths, roller assemblies, and multipoint hardware.
To identify your model, check the white label on the hinge side of the frame; it lists the series, the date of manufacture, and the design pressure rating. The 3750 and 3770 share hinge pin sizes but use different strike plates, a mismatch we have seen twice in Miramar’s Silver Lakes community where a homeowner ordered the wrong OEM kit online. For the 5400 slider, the roller wheel diameter matters: 1-1/2 inch versus 1-3/4 inch, and the wrong size will chew the track within six months.
We source OEM CWS parts where the series is still in production, and we stock quality aftermarket equivalents for discontinued lines. The aftermarket rollers and seals we carry meet the same design pressure ratings, and we document the spec sheet in your file. Sightline Windows & Doors Miramar is an independent service provider, not affiliated with CWS.
Before
AfterSigns Your CWS Door Installation Is Failing
- The door sticks or drags at the bottom. In Miramar, the concrete slab settles and the threshold shifts; the CWS sweep compresses unevenly and the door frame racks. We check with a six-foot level to see if the sill is out of plane before we quote a new sweep or a full rehang.
- Daylight shows around the frame after you close and lock it. The Q-Lon or silicone bulb seal has hardened in the Florida UV. On west-facing CWS doors in Miramar’s Sunset Lakes area, we see this at year six or seven, sooner if the overhang is less than eighteen inches.
- The multipoint lock handle turns but the bolts don’t throw. The gearbox inside the mortise mechanism has stripped, usually from forcing the handle when the door is misaligned. The CWS 3750 uses a Fuhr or Hoppe gearbox depending on the year; we open the mechanism to read the stamp before ordering.
- Condensation forms between the glass panes. The IGU seal has failed. CWS doors with low-E/argon fills lose the gas and the thermal performance drops; the fix is a new insulated glass unit, not a wipe-down.
- The sliding panel jumps the track or rolls rough. The CWS 5400 roller housing has cracked, or the adjustment screw has backed out from vibration. We stock both the stainless and the nylon wheel versions; the stainless set lasts longer on Miramar homes with pool enclosures where chlorine accelerates corrosion.
Replacement Cost & What’s Included

| Service | Typical Range in Miramar |
|---|---|
| CWS seal/sweep replacement (labor + parts) | $180 - $340 |
| CWS multipoint lock hardware repair | $290 - $560 |
| CWS roller/roller housing replacement (sliders) | $240 - $420 |
| CWS IGU replacement (door glass only) | $380 - $720 |
| Full CWS door replacement (standard, prehung) | $890 - $1,650 |
| Full CWS impact-rated door replacement | $1,450 - $2,400 |
The range depends on three things: whether the rough opening is square (we measure diagonals to 1/8 inch), whether the CWS unit is impact-rated (heavier frame, more fasteners, permit required), and whether the interior trim needs replacement after we pull the old frame. Our quote is the measured survey you keep; the final invoice matches it. Every CWS door install carries our 365-Day Done Right Promise under the Haven Standard, and we leave a documented photo record of the finished opening.
DIY or Call Us?
There is one thing a Miramar homeowner can safely check: open the door ninety degrees and sight down the jamb. If you see bowing or if the gap between door and frame narrows at the top or bottom, you have a frame issue, not a part issue. Note the model number from the label and the measurements of the visible gap; that is useful information to bring to the survey.
Where DIY goes wrong with CWS doors: the multipoint lock mechanism is under spring tension, and the mortise chassis is easy to damage if you back out the screws in the wrong order. We have been called to Miramar homes where a homeowner removed the gearbox, lost the alignment of the faceplate, and now the door won’t close at all. The impact-rated frames are also heavy; a 3750 single door with glass can weigh 180 pounds, and two people with the wrong pry bar will bend the threshold. For anything beyond a sweep adjustment or a lubricated hinge, we recommend a measured survey first. Call (754) 260-1468 to schedule yours; the written price comes before any work starts.
FAQs

A properly installed CWS impact-rated door typically lasts 15 to 20 years in South Florida, though the seals and hardware need attention at year 6 to 8. The salt air in Miramar’s lakefront neighborhoods and the UV exposure on west elevations shorten seal life; we inspect these during any service call and note them in the photo record. Call (754) 260-1468 for an exact quote on your specific CWS model; estimates are free.
Yes, if the frame is square and the failure is limited to hardware, seals, or glass. We replace IGUs, gearboxes, rollers, and weatherstrip without touching the frame; we only recommend full replacement when the frame is rotted, the design pressure rating is outdated, or the homeowner wants a different style. Call (754) 260-1468 and we will tell you which category you are in.
A standard prehung replacement in a square opening takes four to six hours; an impact-rated unit with reframing and permit inspection takes one to two days. We do not promise same-day completion on full replacements because the permit and inspection schedule is outside our control, and Haven Clause 2 means we arrive when we say we will. Call (754) 260-1468 to schedule a measured survey and we will give you a written timeline with the price.
We carry CWS-compatible rollers, multipoint lock components, sweep kits, and seal profiles for the 3750, 3770, 5400, and 9800 series. For discontinued CWS lines or custom finishes, we order from our supplier with a three to five day lead time and track the shipment so we arrive once, not twice. Call (754) 260-1468 to confirm stock for your specific model and series.
Sonia Raman grew up in Miami and picked up her first set of glazier’s tools not long after finishing the Building Construction Technology program at Miami Dade College. She has spent more than two decades measuring, ordering, and installing windows and doors across South Florida, and her crew has worked throughout Miramar for years, including retrofits on homes backing up to Lake Lucerne City Park, where impact-rated frames have to hold up to open water exposure on the west elevation. Measure it right the first time. Everything else follows from that.
