AfterCertainTeed Bathroom Remodeling: The Fort Lauderdale Owner’s Guide
We stock and install CertainTeed-compatible bathroom systems in Fort Lauderdale, with typical full remodels running $9,000-$28,000 installed and partial updates starting lower. Most CertainTeed products we see are wall systems, backer boards, and moisture-barrier components that fail slowly enough for owners to catch early. In Fort Lauderdale’s salt-air climate, the first sign is usually soft drywall behind tile or a musty smell that doesn’t clear with ventilation - both point to the waterproofing layer, not the tile itself.
Which CertainTeed Models This Applies To
CertainTeed’s bathroom product line centers on three systems we encounter regularly in Fort Lauderdale homes: GlasRoc Tile Backer (the purple-faced cement board), DiamondBack Tile Backer (the textured, ready-to-tile panel), and the older PermaBase family still present in pre-2015 remodels. The label matters because GlasRoc and DiamondBack use different fastening patterns and joint treatments - mixing the two on the same wall creates a plane change that telegraphs through tile.
To identify what you have, look for the printed code on the board face or edge. GlasRoc carries a “GR” prefix; DiamondBack shows “DB” and a grid pattern molded into the surface. PermaBase is smooth gray with a stamped logo. For repairs, we match the existing substrate rather than overlaying, since Fort Lauderdale’s humidity makes trapped layers a mold risk. OEM CertainTeed board is our default, though we stock equivalent Georgia-Pacific DensShield for same-day jobs when the color match isn’t critical - both carry ASTM C1325 Type A certification, which is what the code actually requires.
Signs Your CertainTeed Bathroom Remodeling Is Failing
- Soft spots near tub or shower corners. This indicates the GlasRoc or PermaBase has taken on moisture past the face paper. In Fort Lauderdale, we see this most in homes where the exhaust fan was undersized for the room volume - the board wicks slowly, then the paper delaminates.
- Tile cracks in a straight line along a seam. The backer board joint wasn’t taped with alkali-resistant mesh and thinset, or the tape failed. CertainTeed’s systems require specific treatment at seams; skipping it or using drywall tape guarantees a crack within two years in our climate.
- Grout turning dark and staying dark. Persistent darkening means water is reaching the substrate. If the backer is DiamondBack, the plastic barrier may be intact but the fastening flange is weeping - a detail most DIYers miss.
- Musty odor that improves when the AC runs hard. The moisture barrier behind the backer board is compromised. In Fort Lauderdale’s older homes, especially in neighborhoods like Victoria Park, we find original felt paper or no barrier at all behind 1980s PermaBase.
- Loose fixtures or towel bars. The backer board wasn’t installed to blocking, or the installer used drywall anchors instead of toggle bolts into the cement board. GlasRoc will hold a toggle properly; DiamondBack’s grid pattern can shred standard anchors if you’re not precise.

AfterReplacement Cost & What’s Included
| Scope | Price Range (Fort Lauderdale) | What’s Included |
|---|---|---|
| Backer board replacement, tub surround | $3,500-$7,500 | Demo to studs, new CertainTeed or equivalent board, waterproofing, tile-ready finish |
| Full bathroom remodel | $9,000-$28,000 | Complete gut, new substrate, fixtures, tile, paint, permit coordination |
| Small bathroom (5’×8′ or less) | $5,000-$12,000 | Same scope, compact footprint, often stackable washer/dryer accommodations |
| Shower replacement only | $3,000-$8,500 | Pan, walls, valve, door - backer board included as needed |
The range depends on three factors: how far the moisture traveled (studs replaced or treated), whether we hit cast iron plumbing that needs cutting, and tile selection - porcelain at $3-$8 per square foot installed versus natural stone at $12-$20. Under Clause 1 of the Haven Standard, you get the written price before anyone picks up a tool. No change proceeds without a signed change order, which is why our projects finish within a few percent of the number you agreed to.
DIY or Call Us?
There’s a safe middle ground here. A homeowner can check the exhaust fan CFM rating against the room volume - multiply length by width by height, divide by 60, and you need at least that many cubic feet per minute. You can also look for the printed code on your backer board and photograph any soft spots for us to review.
Where DIY goes wrong is the waterproofing layer. CertainTeed systems require specific seam treatment and, in Fort Lauderdale’s code jurisdiction, a flood test on shower pans before tile goes on. The flood test is 24 hours at the curb height - skip it, and you’re relying on caulk and hope. We don’t recommend homeowners remove tile or backer board themselves; the dust is silica-laden, and old Fort Lauderdale homes often have asbestos in the joint compound behind 1980s remodels. Call (754) 254-7676 and we’ll scope it, photograph it, and put the price in writing before any work starts.
FAQs
Properly installed GlasRoc or DiamondBack lasts 25-30 years in Fort Lauderdale’s climate, but the waterproofing layer in front of it - the RedGard, Hydro Ban, or similar - is the real lifespan limiter. That membrane typically needs attention at 10-15 years, sooner if the exhaust fan is undersized or the window stays shut. Call (754) 254-7676 for an exact quote - estimates are free.
Spot repairs work only if the damage is smaller than a sheet and the surrounding board is bone-dry. In practice, moisture travels horizontally behind tile faster than you’d expect, so we usually find more damage once we open the wall. We photograph everything before and after demo so you see what we found, not what we guessed. Call (754) 254-7676 for an exact quote - estimates are free.
A typical full remodel runs 10-14 business days from demo to final walkthrough, assuming no plumbing relocation and standard tile in stock. Custom orders or cast iron drain replacement adds 3-5 days. We don’t promise same-day completion on planned remodels - that’s not how careful work happens - but we do keep to the written schedule we give you at signing. Call (754) 254-7676 for an exact quote - estimates are free.
We stock GlasRoc and DiamondBack in 1/2″ and 5/8″ thicknesses, plus the alkali-resistant mesh and fasteners CertainTeed specifies. For full remodels, we pull from our supplier in Pompano Beach same-day if we need additional sheets. We also stock KraftMaid, Cambria, and Silestone for clients who want to bundle cabinet or countertop work. Call (754) 254-7676 for an exact quote - estimates are free.
