CWS Door Installation: The Lantana Owner’s Guide

CWS door installation in Lantana typically runs $890-$2,400 depending on the series, impact rating, and whether the frame needs reframing. We stock CWS-compatible hardware, sills, and jamb components on our trucks, and most replacements are completed in a single visit. Most Lantana homeowners discover a CWS door is failing when the sweep drags, the multipoint lock won’t engage, or they see daylight between the frame and the jamb after a storm.

Which CWS Models This Applies To

CWS builds three door series that circulate in South Florida: the Aventura impact-rated line, the Classic non-impact vinyl series, and the Estate aluminum entrance system. The Aventura uses a 2-1/4 inch thick extruded aluminum frame with a proprietary multipoint lock mortised at 45 inches on center; the Classic carries a 1-3/4 inch vinyl frame with a standard single-point latch; the Estate runs 2-5/8 inch aluminum with a commercial-grade continuous hinge option. Each series stamps its model prefix on the hinge-side jamb label, usually behind the interior trim.

We see the most confusion around the Aventura 5500 and 7500 series, which share the same frame depth but use different strike plate depths. The 5500 takes a 7/8 inch throw; the 7500 needs 1-1/8 inch. Order the wrong multipoint and the deadbolt won’t clear the jamb. For CWS parts, we source OEM hardware direct from the CWS distribution center in Medley when the lead time is under five days. When a Lantana customer needs faster turnaround, we stock aftermarket multipoint kits from Truth Hardware that match the Aventura hole pattern and carry the same 10-year finish warranty. We are an independent service provider with no affiliation to CWS.

Signs Your CWS Door Installation Is Failing

• The sweep drags or the door sticks in the frame. CWS vinyl frames in Lantana absorb moisture during humid months and can swell 1/16 inch, but persistent dragging usually means the sill cap has flattened or the adjustable threshold screws have backed out. We check with a 4-foot level; anything over 1/8 inch out of plane means the sill assembly needs replacement, not just adjustment.
• Daylight visible around the frame perimeter. This means the seal gasket has compressed past recovery or the frame has pulled from the rough opening. In Lantana, salt air hardens EPDM gaskets in four to six years, faster than the inland rating. We replace with silicone bulb seals rated for coastal exposure.
• Multipoint lock won’t engage or the handle spins. The CWS Aventura gearbox uses a zinc alloy housing that cracks if the door is slammed repeatedly. Once the gearbox splits, the spindle can’t transfer motion to the shoot bolts. We stock the MCM-5000 aftermarket gearbox, which fits the Aventura cutout and uses a brass housing.
• Condensation between the glass layers. CWS doors with integrated blinds or impact glass use a dual-seal system. Seal failure in South Florida is usually sun-driven: the southwest exposure on a Lantana beachfront home can push glass surface temperatures past 140°F, accelerating desiccant saturation. The glass unit needs full replacement; resealing is not code-compliant for impact-rated assemblies.
• The door closes but won’t latch without lifting or shoving. This is hinge sag, either from stripped screws in the jamb or a bent hinge knuckle on a heavy impact door. CWS Estate doors with full-lite glass panels run 180-220 pounds; standard residential hinges fatigue under that load. We upgrade to ball-bearing hinges with #12 x 3 inch structural screws into the framing.

Replacement Cost & What’s Included

The range depends on three factors: whether the existing frame is square (we measure diagonals to 1/8 inch), whether the rough opening needs structural repair, and whether the replacement must match a specific CWS finish code. Our written quote lists each line item separately. Haven Clause 1 means the measured survey and the final invoice are the same document. Every CWS door installation we complete in Lantana carries the 365-Day Done Right Promise and leaves a documented photo record.

DIY or Call Us?

An owner can safely check three things: whether the threshold screws are loose, whether the strike plate is aligned with a pencil mark test, and whether the sweep is clogged with debris. Beyond that, CWS impact doors present real hazards. The multipoint lock stores spring tension in the gearbox; releasing it without supporting the door can drop a 200-pound slab on hands or feet. Impact glass units weigh 8-12 pounds per square foot and require two people with suction cups for safe handling. If the frame needs reframing, you’re cutting into a structural opening that may carry wind-load requirements under Palm Beach County code.

We don’t write this to discourage anyone who knows their way around a level and a screwgun. We write it because we’ve been called to Lantana jobs where a homeowner stripped the CWS proprietary strike mortise or cracked the jamb trying to force a standard latch into an impact-rated prep. The fix cost more than the original call would have. Call (561) 461-2062 and we’ll schedule a measured survey. You’ll get the written price before any work starts, and the number won’t change.
