Wellborn Windows & Doors: The South Florida Owner’s Guide
We stock and install Wellborn-compatible windows and doors across South Florida, with most replacement projects running $4,500-$15,000 for standard window replacement and $8,000-$25,000 for impact-rated installations. Same-day assessments are available, and we carry common Wellborn hardware and seal components on our trucks. Most homeowners realize something’s wrong when they notice drafts around the frame, condensation between glass panes, or the sash refusing to stay open - signs that the weatherstripping, balance system, or insulated glass unit has reached its limit in our coastal climate.
Which Wellborn Models This Applies To
Wellborn produces several window and door series, and the part you need depends on when your unit was manufactured. The Wellborn 400 Series and 700 Series casement and double-hung windows use proprietary balances and tilt latches that differ from their entry-level 200 Series line. Check the etched marking in the glass corner or the sticker on the frame edge - you’re looking for a four-digit model code and a two-digit year stamp. We’ve seen homeowners in Coral Gables and Fort Lauderdale order the wrong balance length by an inch because they measured the visible sash rather than the concealed channel; the actual balance spec is stamped on the metal channel itself, visible only when you tilt the sash inward.
For Wellborn doors, the multipoint lock systems vary between their fiberglass entry lines and aluminum patio sliders. The OEM multipoint lock assembly runs higher than quality aftermarket equivalents from Truth Hardware or Hoppe, but only the OEM maintains the exact backset and faceplate contour for seamless latching. We source both and will show you the difference before ordering. Groundwork Construction Co. of South Florida is an independent service provider - we’re not affiliated with Wellborn - which means we shop the part that solves your problem without pushing one supplier.
Signs Your Wellborn Windows & Doors Is Failing
- Sash drops or won’t stay open. The coil or block-and-tackle balance system has lost tension. In South Florida’s salt air, we’ve seen balances corrode internally in 8-12 years rather than the 15-20 you’d expect inland.
- Condensation between double-pane glass. The insulated glass unit (IGU) seal has failed, allowing humid Gulf Stream air inside. Once the desiccant saturates, the fogging becomes permanent and the Low-E coating degrades.
- Draft even when closed and locked. Compression weatherstripping has flattened or the bulb seal has cracked from UV exposure. South Florida’s year-round sun hardens rubber faster than seasonal climates.
- Difficulty locking or unlocking. The multipoint lock mechanism has shifted with frame settling, or internal corrosion is binding the rods. Forced operation bends the keepers and compounds the damage.
- Visible frame rot or swelling at the sill. Water intrusion through failed end dams or weep holes blocked by pollen and insect debris. In coastal South Florida, this accelerates dramatically if the exterior isn’t caulked at the head flashing.

What drives the range: unit size, floor level (ladder vs. scaffold access), whether the original frame is square and salvageable, and whether you’re matching existing trim profiles. Our quotes itemize parts, labor, and disposal - no lump-sum mystery. We warranty our installation workmanship and pass through any manufacturer material warranty in full. Call (844) 665-0162 for an exact quote; estimates are free.
DIY or Call Us?
There’s plenty a homeowner can safely inspect. Open the sash fully, check the weep holes at the sill for debris, and look for the model stamp while you’re there. If the IGU is fogged, note whether it’s the top or bottom lite - that tells us which seal failed.
Where DIY goes wrong: replacing a window balance under tension can release a metal coil at speed, and cutting into a door frame to access a multipoint lock risks voiding your impact rating certification. We’ve been called to jobs in Hollywood and Aventura where a well-meaning owner bent the balance channel or stripped the lock rod threads. Do it right the first time or you’ll do it twice - and the second time always costs more. For anything involving glass removal, frame disassembly, or lock mechanism work, call (844) 665-0162 and we’ll assess it properly.
FAQs
Expect 15-25 years for the frame and sash, but seals, balances, and weatherstripping typically need attention at 8-12 years due to UV, salt, and humidity exposure. Call (844) 665-0162 for an exact quote - estimates are free.
Often yes - IGU replacement, balance swaps, and hardware repairs are straightforward if the frame is structurally sound and not rotted. Full replacement only makes sense when you’re upgrading to impact-rated glass or the frame itself has failed. Call (844) 665-0162 for an exact quote - estimates are free.
A single unit swap takes 2-4 hours; a whole-house window project typically runs 2-5 days depending on count and access. We coordinate permits and inspections so you’re not chasing paperwork. Call (844) 665-0162 for an exact quote - estimates are free.
