Pool Mastic

Water getting under your deck causes problems that affect more than just the deck itself. Settled pavers create trip hazards. Washed-out soil undermines pool plumbing. Cracks in the deck let dirt and debris wash into your pool. Proper mastic prevents all of these issues by keeping water where it belongs.

Weatherford’s clay soil makes mastic failures worse. When water seeps under your deck, it saturates the expansive clay underneath. That clay swells when wet and shrinks when dry, causing dramatic movement that cracks concrete, shifts pavers, and can even affect your pool shell. Keeping water out with good mastic protects your entire pool structure.

Different deck materials require different mastic approaches. Concrete decks need mastic that bonds well to rough surfaces. Travertine and natural stone need mastic that won’t stain the porous material. Pavers require careful application so excess mastic doesn’t squeeze up between stones. We match the mastic type and application method to your specific deck.

Color matching matters for appearance. Mastic comes in gray, tan, white, and other colors to blend with your coping and deck. We bring samples to match your existing materials so the finished joint looks clean and professional, not like an obvious repair.

Application temperature affects how well mastic cures. Too hot and it dries before bonding properly. Too cold and it doesn’t set up right. We schedule mastic work for morning or late afternoon during summer, and midday during cooler months, to get the best curing conditions.

The curing process takes 24 to 48 hours. During that time, the mastic needs to stay dry and undisturbed. We protect fresh mastic from sprinklers, pool splashing, and foot traffic until it’s fully set. Walking on uncured mastic damages the seal and creates failure points.

Pool resurfacing is the perfect time for mastic replacement. When we’re already working on your pool shell, replacing deteriorated expansion joint material adds minimal time and cost compared to doing it as a separate project later. We coordinate mastic work with other renovation projects for efficiency.

Mastic life depends on maintenance and exposure. Joints in full sun break down faster from UV damage. Joints that get constant water exposure from splashing or deck drains deteriorate quicker. Well-maintained mastic in protected areas can last seven to ten years. Exposed joints in harsh conditions might need replacement every three to five years.

Failed mastic creates bigger problems over time. What starts as a small crack becomes a wide gap. Water infiltration undermines more deck area. Repair costs multiply as damage spreads. Replacing bad mastic early prevents expensive deck reconstruction later.

Some pools have multiple expansion joints—between the coping and deck, between deck sections, around stairs, and at equipment pads. We inspect all joints and prioritize which ones need immediate attention versus which can wait. Not every joint fails at the same rate, so we give you options based on urgency and budget.

DIY mastic installation usually fails because homeowners skip preparation steps, use the wrong materials, or apply it in poor weather conditions. The material cost is low, but the labor and expertise make the difference between a repair that lasts years and one that fails in months.

We serve Parker County families who want their pool decks protected from water damage. Whether you’re in Weatherford, Aledo, Brock, or nearby areas, we bring the right materials and installation methods to seal expansion joints properly and keep water from destroying your deck investment.
