GAF Kitchen Remodeling: The Long Beach Owner’s Guide
GAF kitchen remodeling in Long Beach typically costs $14,000 – $45,000 installed, and most full-kitchen overhauls run 6 – 10 weeks from tear-out to final walkthrough. We stock GAF-compatible waterproofing, underlayment, and flashing components on our trucks, so if your GAF barrier failed and water got into the cabinets or subfloor, we can usually start the repair within a few days. Most Long Beach homeowners discover the problem the same way: a soft spot under the sink, swollen cabinet bases, or a musty smell that won’t go away. GAF isn’t a cabinet brand, but its waterproofing membranes and underlayment systems sit underneath many Long Beach kitchens, especially in homes built or renovated after 2010.
Here’s what this page covers: which GAF products show up in kitchen remodels, how to tell if yours is failing, what replacement costs in Long Beach, and whether you should touch it yourself. The short version: if water is involved, call us. The number is (562) 512-6480.
Key Takeaways
- GAF kitchen remodeling in Long Beach runs $14,000 – $45,000 depending on scope, cabinet grade, and countertop material.

- Every job gets a written price before work starts, backed by our 365-Day Done Right Promise.
Which GAF Models This Applies To

In kitchen remodeling, GAF products fall into two buckets: moisture barriers and roofing underlayment that sometimes extends over kitchen additions or bump-outs. The ones we see most in Long Beach are GAF WeatherWatch and StormGuard leak barriers, GAF Deck-Armor breathable underlayment, and GAF Shingle-Mate roofing felt used on flat-roof kitchen extensions common in older Belmont Shore and Alamitos Heights homes.
Here’s the compatibility gotcha most people miss: GAF StormGuard is a peel-and-stick ice and water shield rated for roof pitches 2:12 and steeper. If a contractor wrapped it around a kitchen bay window or used it as a general moisture barrier on a flat roof, it won’t drain properly, and you’ll get pooling. We see this on 1950s and 1960s Long Beach ranch homes where a kitchen pop-out was added decades ago with whatever material was on hand. The fix is pulling the old barrier, repairing any rotted framing, and reinstalling the correct GAF product for the actual roof pitch.
OEM GAF materials carry a manufacturer warranty but only when installed to spec. Quality aftermarket equivalents exist, but for waterproofing layers that sit under tile, cabinets, and flooring, we recommend staying with GAF product for GAF projects. The cost difference is usually a few hundred dollars on a project where a failure costs thousands.
Styles & brands we work with







Signs Your GAF Kitchen Remodeling Is Failing
- Swollen cabinet bases or toe kicks. Water wicks up from the subfloor, and MDF or particleboard cabinets swell first. If you see the bottom edge of a cabinet looking puffy or the finish peeling at the base, moisture is getting in from below.
- Soft spots in the floor near exterior walls. A failed underlayment lets water travel along the plywood seam. In Long Beach’s damp winter months, even a small breach shows up as a springy floorboard within weeks.
- Musty smell that comes back after cleaning. Trapped moisture between the barrier and subfloor doesn’t dry out on its own. You can scrub the surface all you want, but the smell returns because the water source is underneath.
- Discolored grout or caulk pulling away from exterior-facing walls. When the substrate moves from moisture, grout cracks and caulk separates. In kitchens near the coast, like Naples or the Peninsula, salt air accelerates this once moisture breaches the barrier.
- Cabinets near the sink or dishwasher feel damp, not just wet after a spill. Dishwasher leaks are a separate issue, but if the cabinet interior feels humid days after a cycle, water is trapped in the cavity, not draining.
Replacement Cost & What’s Included

GAF kitchen remodeling in Long Beach costs $14,000 – $45,000 installed. The range breaks down like this: a partial repair (failed barrier under a 10×10 kitchen, new subfloor, reinstall existing cabinets) runs $9,000 – $15,000. A full kitchen remodel with new GAF underlayment, cabinets, countertops, and flooring lands in the $25,000 – $45,000 range depending on materials.
| Scope | Typical Long Beach Range |
|---|---|
| Barrier repair + subfloor replacement (repair only) | $9,000 – $15,000 |
| Full kitchen remodel with GAF waterproofing | $14,000 – $45,000 |
| Countertop installation (quartz or stone) | $2,000 – $6,500 |
| Cabinet installation (new, all boxes) | $4,000 – $13,000 |
| Backsplash installation | $800 – $2,500 |
What drives the price: kitchen size, whether we’re pulling and resetting existing cabinets or installing new ones, and how much framing damage the water caused. Older Long Beach homes with true 2×4 framing and spaced floor joists require more structural work than newer builds. Every quote includes the same things: written price before we start, live arrival tracking, before-and-after photos, and the 365-Day Done Right Promise in writing. If the repair isn’t done right, we make it right, no argument.

You can check a few things safely. Look for visible water stains under the sink, feel for soft spots along the floor, and check if cabinet bases are pulling away from the wall. That’s the diagnosis part, and it costs you nothing.
The repair part is where DIY goes wrong. Waterproofing layers sit under finished flooring and cabinets. Getting to them means pulling cabinets, removing flooring, and cutting out subfloor. If you misalign the new barrier, water finds the seam and you’re back to square one. We’ve fixed enough homeowner attempts in Signal Hill and Bixby Knolls to know the pattern: the first repair works for six months, then the smell comes back. Call (562) 512-6480 for a free estimate. Luca Romano will walk your kitchen with you and show you exactly what’s failing before any price is written.
FAQs

GAF moisture barriers and underlayment typically last 15 – 25 years in Long Beach’s climate. Coastal humidity and salt air near the water can shorten that to 10 – 15 years for homes within a mile of the ocean, especially if the original install wasn’t ventilated properly. Call (562) 512-6480 and we’ll inspect yours for free.
Small breaches near a single seam can sometimes be patched, but if water has already reached the subfloor, patchwork buys you time, not a fix. Long Beach moisture doesn’t dry out on its own under tile and cabinets. Luca Romano will give you an honest read: repair what’s repairable, replace what’s not.
A barrier and subfloor repair in a standard Long Beach kitchen takes 3 – 5 working days. A full remodel runs 6 – 10 weeks. We coordinate cabinet, countertop, and flooring crews so you’re not waiting between trades, and you get photo updates before and after each phase.
We stock GAF-compatible waterproofing, flashing, and underlayment on our trucks for common Long Beach kitchen repairs. Specialty GAF products or unusual sizes may take 2 – 3 days to order. We’ll tell you upfront in the written quote if anything needs to be ordered.
No. The written price we give you before work begins is the price you pay, unless you approve a change in writing. If we find hidden rot during tear-out, we stop, show you photos, and give you a written price for the additional work before touching it. No surprises, no end-of-job invoice shock.
