Therma-Tru Door Installation: The Hollywood Owner’s Guide

Complete Therma-Tru door installation in Hollywood typically runs $1,800 to $4,200 depending on series, impact rating, and whether the frame needs reworking. We stock Therma-Tru-compatible hardware, sills, and jamb components on our Hollywood trucks, and most installs are completed in a single day once the measured survey is approved. If your door is dragging, leaking air, or the multipoint lock won’t engage, the issue usually traces to installation shift, sill compression, or hinge-side settlement after one of our wet seasons.

Most Hollywood owners discover a problem when the door sticks in August humidity or when water pools at the threshold after a storm. The gap they noticed in January has become a binding edge by summer. We see this pattern repeatedly in Hollywood’s older slab construction, particularly in neighborhoods like Hollywood Hills and the Historic Oakridge area where original openings weren’t plumb to begin with.

Which Therma-Tru Models This Applies To

Therma-Tru organizes its entry systems by material platform: Classic-Craft (fiberglass), Fiber-Classic (textured fiberglass), Smooth-Star (paint-ready fiberglass), and Pulse (flush-glaze contemporary). Each series uses distinct jamb depths, hinge mortise spacing, and multipoint lock prep locations. A Classic-Craft Mahogany Collection door requires a 4-9/16″ jamb with specific backset for the Tru-Lock multipoint hardware; drop a Fiber-Classic into that same rough opening without adjusting the hinge stile and the deadbolt won’t align.

We identify the correct series by the door’s edge label, usually a white sticker with the NAFS performance grade and the model code starting with CCM, FCC, or SCC. The label also lists the design pressure rating, critical in Hollywood where the Broward County wind zone requires impact-rated or protected openings. For Therma-Tru specifically, we source OEM sills, compression seals, and hinge screws where the spec demands it; for hardware, we often use quality aftermarket equivalents that meet the same BHMA Grade 2 standards at lower cost. The decision depends on whether the customer is matching an existing multi-door installation or starting fresh.

Signs Your Therma-Tru Door Installation Is Failing

• The door drags at the bottom corner. This usually means the sill has compressed or the frame has settled on the hinge side. In Hollywood, we see this after heavy rain events when the slab edge swells or the shims beneath the frame compress. The fix is rarely the door itself; it’s re-leveling the frame and replacing the adjustable sill cap.
• Daylight visible around the weatherstrip. Therma-Tru’s Q-Lon compression seals harden after four to six years of Florida UV exposure. Once the bulb loses resilience, air and water bypass the seal. We replace with OEM Q-Lon or upgrade to silicone bulb weatherstrip on coastal Hollywood homes where salt accelerates degradation.
• The multipoint lock won’t engage at all three points. This indicates frame racking or latch misalignment. The Tru-Lock system depends on precise keeper alignment; a 1/8″ shift at the header throws off the bottom shootbolt. We check with the door closed and a flashlight against the edge to locate the binding point.
• Condensation between the door glass and the storm panel. On Therma-Tru doors with decorative glass or venting sidelites, the IGU seal fails and fogs. This is a glass replacement, not a door replacement, but we verify the frame hasn’t leaked and damaged the subfloor first.
• The door closes but won’t latch without shoulder pressure. This is early-stage hinge failure or screw pullout from the jamb. Therma-Tru’s hinge screws are #12 x 3″ into the frame; if the installer missed the stud or used standard 2-1/2″ screws, the weight of a fiberglass slab gradually works the hinge loose.

Replacement Cost & What’s Included

The range reflects three variables: whether the rough opening needs reframing, whether impact-rated glass is required by Hollywood’s location in the High-Velocity Hurricane Zone, and whether the interior trim must be preserved or replaced. Our measured survey documents all three before any work begins; the written quote matches that document exactly under Haven Clause 1. Every Therma-Tru installation includes the 365-Day Done Right Promise, a documented photo record, and the measured survey the customer keeps. We do not charge separately for permit pull or inspection scheduling in Hollywood or Broward County.

DIY or Call Us?

An owner can safely check three things: whether the hinge screws are tight to the frame, whether the sill cap adjusts with a Phillips head, and whether weatherstrip is visibly cracked or detached. Beyond that, Therma-Tru door installation involves risks that justify a professional. Fiberglass slabs weigh 80 to 140 pounds; a solo lift risks back injury and corner damage. The multipoint lock requires precise mortising and keeper alignment; mis-cut and you’ve voided the door warranty and damaged the frame. Most critically, impact-rated installations must pass Miami-Dade or Florida Product Approval inspection; a DIY install cannot be permitted and will fail a home sale inspection in Hollywood.

We carry Therma-Tru-compatible sills, weatherstrip, and multipoint hardware on our Hollywood trucks. Call (754) 714-7309 to schedule your free measured survey. We’ll read your existing label, check the rough opening, and hand you a written price before any work starts.
