CWS Door Installation: The Kendall Owner’s Guide

CWS door installation in Kendall typically runs $1,800-$4,200 for a standard single entry door, depending on the series and whether the opening needs reframing. We stock CWS-compatible hardware, seals, and frame components on our trucks, and most replacements can be surveyed and quoted same-day. Most Kendall homeowners realize their CWS door is failing when the sweep drags, the multipoint lock won’t engage, or they spot daylight between the jamb and the frame after a heavy rain.

Which CWS Models This Applies To

CWS manufactures several door lines common in Kendall homes built between 2015 and 2022: the Windpact Plus impact-rated series, the 400 Series vinyl patio doors, and the aluminum commercial-grade entries found in many Dadeland-adjacent townhomes. The critical compatibility check is the hinge barrel diameter and the multipoint lock backset measurement, which varies between the residential and commercial lines.

To identify your exact model, look for the CWS label on the hinge side of the door slab or the etched code on the glass corner. The Windpact Plus uses a 45mm backset on its multipoint hardware; the 400 Series patio door uses a 35mm backset and a narrower stile. Mixing these up means new holes in your jamb and a compromised seal.

We carry both OEM CWS hardware and verified equivalents from Truth Hardware and Hoppe that match the original specs. For impact-rated doors, we specify only components that maintain the NOA certification; substituting standard hardware voids the rating and, in Kendall’s Miami-Dade wind zone, that’s a code issue.

Signs Your CWS Door Installation Is Failing

• The door sticks seasonally or won’t latch without lifting. This usually means the frame has settled or the hinges have elongated their screw holes. In Kendall’s coral-rock substrate, minor foundation shift is normal; the fix is often re-shimming the frame, not replacing the door.
• Water pools at the threshold after rain. The CWS sweep or sill cap has compressed or torn. On south-facing doors, UV exposure degrades the vinyl sweep in about 5-7 years, faster than the manufacturer spec suggests for northern climates.
• Draft or light visible around the perimeter. The compression seal has lost its memory or the frame has pulled away from the rough opening. Check the upper corners first; that’s where Kendall’s afternoon sun does the most thermal cycling damage.
• The multipoint lock is hard to turn or makes grinding noise. The gearbox is failing or the keeps have shifted. CWS multipoint gearboxes are model-specific; the wrong replacement won’t align with the existing keeps.
• Condensation between glass panes on an insulated door. The IGU seal has failed. For CWS doors with integral blinds, this requires a full sash replacement; the blind cavity cannot be resealed in the field.

Replacement Cost & What’s Included

What drives the range: the condition of the rough opening, whether the existing frame is plumb and square, and whether the door is impact-rated (heavier hardware, longer install). Every quote we write in Kendall includes the measured survey document, the written scope, and the final invoice as one document under Haven Clause 1. No change orders. The 365-Day Done Right Promise covers the installation and hardware. We pull permits when required by Miami-Dade code and pass inspection before we consider the job closed.

DIY or Call Us?

There’s a short list of checks any homeowner can make safely: verify the door is contacting the weatherstrip evenly, look for visible screw loosening at the hinges, and confirm the threshold drain holes aren’t clogged with debris. These take ten minutes and a flashlight.

What we don’t recommend: adjusting or replacing multipoint lock gearboxes, removing impact-rated door slabs (they’re 90-120 pounds and awkward), or cutting into the frame to correct settling. Improper shimming transfers load to the wrong points and voids the manufacturer’s warranty. We’ve re-done three Kendall jobs this year where a homeowner’s well-intentioned adjustment cracked the jamb or misaligned the lock so badly the door wouldn’t secure.

Measure once, document it, then cut. That’s how we work, and it’s why we photograph every opening before we touch it.

Call (786) 321-3319 to schedule your free measured survey. We’ll bring the CWS-compatible hardware, write the price before any work starts, and leave you with the photo record and the Haven Standard warranty.
