CWS Door Installation: The Tamiami Owner’s Guide

CWS door installation in Tamiami typically runs $1,800-$4,200 for a standard single entry unit, depending on impact rating, frame material, and whether the rough opening needs reframing. We stock CWS-compatible frames, sills, and hardware on our trucks, and most replacements are measured, ordered, and installed within one to two weeks of the initial survey. Most Tamiami owners discover their CWS door is failing when the sweep drags, the multipoint lock won’t engage, or they see daylight between the jamb and the frame after a storm season.

Which CWS Models This Applies To

CWS builds several door lines that circulate in South Florida, and not every frame is interchangeable. The CWS 3750 Series and CWS 5000 Series are the two we encounter most often in Tamiami - the 3750 is a non-impact aluminum frame common in pre-2018 construction, while the 5000 Series carries Miami-Dade NOA impact certification and uses a thicker jamb with integrated reinforcement channels. You can identify your series by the etched mark on the hinge-side jamb, usually 12 inches above the threshold, or by the label inside the top track on a sliding unit.

The OEM-vs-aftermarket question matters specifically with CWS because their multipoint locking hardware uses a proprietary backset spacing - 45 millimeters on the 5000 Series, 40 millimeters on the 3750. We source direct from CWS distribution for lock bodies and keep Truth Hardware and HOPPE equivalents on the truck for after-hours failures. For frames and sills, we match the exact extrusion profile; a generic replacement will leak at the threshold within two Miami wet seasons. We’ve learned this from reframing jobs in Tamiami where a previous installer used a universal sill that never seated against the slab.

Signs Your CWS Door Installation Is Failing

• The threshold gap widens after rain. CWS sills are aluminum with a composite cap; once the cap cracks, water wicks into the subfloor and the frame torques. In Tamiami, we see this accelerated by the limestone substrate shifting seasonally.
• The multipoint lock requires shoulder pressure to engage. This usually means the keepers have drifted out of alignment - common after repeated door slams, but also a sign the hinge screws are backing out of a stripped jamb.
• Daylight shows at the header or strike side. On impact-rated CWS units, this indicates the frame has pulled from the buck or the compression seal has hardened. It defeats the pressure rating and voids the NOA compliance if unaddressed.
• The door hangs lower on the handle side. Hinge pin wear or jamb rot at the bottom corner. On CWS 3750 units without thermal breaks, condensation accelerates corrosion at the lower hinge mortise.
• Operation gets stiffer in summer, looser in winter. Aluminum expands roughly 1/8 inch per 10 feet of frame across South Florida’s temperature swing. If the install didn’t leave proper clearance, the door binds against the jamb or the sweep drags.

Replacement Cost & What’s Included

What drives the range: impact versus non-impact, jamb depth (4-9/16 inch standard versus 6-9/16 inch for block construction), and whether the existing buck is square within 1/4 inch. Our quote includes the measured survey you keep, the written scope, the CWS unit or verified equivalent, installation, shimming, insulation, trim, and the documented photo record. The 365-Day Done Right Promise applies to every installation. We pull permits and schedule inspections; Haven Clause 5 means no surprise add-ons once the written price is set.

DIY or Call Us?

There is one thing a Tamiami owner can safely check: remove the hinge pins, clean them, and verify the screws bite firmly. If they spin freely, the jamb is stripped and the door will sag again within weeks.

Everything else - reframing, impact-rated hardware alignment, threshold sealing to Miami-Dade flood-zone requirements - is where DIY goes wrong. We’ve been called to jobs near Tamiami Trail where a homeowner replaced the lock body with a big-box equivalent that didn’t match the 45-millimeter backset; the door wouldn’t latch, and the new holes compromised the jamb integrity. Another job near the Miccosukee Resort corridor had a self-installed sill that pitched inward, trapping water against the slab. The subfloor was rotted six inches back.

We carry CWS-compatible frames, sills, and multipoint hardware. Call (786) 321-9118 to schedule your free measured survey. The written quote is the same document we install from.
