How Much Does a Pool Remodel Cost in Houston in 2026?

If your pool is 15, 20, or 30+ years old, chances are the plaster is rough, the tile is stained, and the equipment is on its last leg. Before you call anyone, it helps to know what you're actually looking at cost-wise. Here's a real breakdown of what pool remodeling and repair projects run in the Houston area in 2026, based on the work we see every week across Sugar Land, Katy, The Woodlands, and the rest of Greater Houston.

Pool Replastering Costs

Replastering is the most common remodel request we get, and it's usually the first thing that needs attention on an older pool. Costs vary based on pool size, plaster type, and how much prep work (old plaster removal, surface repair) is needed.

Pool size is the biggest driver here — a standard 15,000-gallon pool will land on the lower end, while larger custom-shaped pools with tanning ledges or spas run higher.

Coping and Tile Replacement

Coping and waterline tile take a beating from Houston's sun, hard water, and freeze-thaw cycles in winter. Cracked or lifting coping isn't just cosmetic — it can let water get underneath the pool shell.

• Waterline tile replacement: $25 – $45 per linear foot
• Coping replacement (per linear foot): $35 – $65, depending on material (poured concrete, natural stone, pavers)
• Full coping + tile package: $6,000 – $12,000 for an average-sized pool

Mastic Repair

Mastic is the flexible expansion joint between your pool deck and the coping. When it fails, water gets underneath the deck and can undermine the whole structure over time. This is a smaller-ticket item but an important one to catch early.

Equipment Upgrades

Older pools often still run on single-speed pumps and outdated filters that cost far more to run than modern equipment. Upgrading is one of the fastest-paying-off remodel decisions homeowners make.

• Variable-speed pump upgrade: $1,200 – $2,200 installed
• Cartridge or DE filter replacement: $800 – $2,000
• Pool heater installation: $2,500 – $5,500
• Full automation system (app-controlled): $1,800 – $3,500

Calcium Removal

Houston's hard water leaves calcium deposits on tile and plaster that build up over years. Removal cost depends on severity and method (acid wash vs. mechanical/bead blasting).

Typical range: $500 – $1,800 depending on pool size and buildup severity.

Leak Detection

If your pool is losing more than about a quarter-inch of water per day beyond normal evaporation, it's worth having a professional leak detection done before assuming the worst.

Typical leak detection service: $300 – $600, often credited toward the repair if you move forward.

Patio Covers and Outdoor Kitchens

These are bigger-ticket additions that often get bundled into a full backyard remodel alongside pool work.

• Patio cover (standard aluminum/wood): $6,000 – $18,000 depending on size and materials
• Outdoor kitchen (basic to mid-range): $8,000 – $25,000+

Pool Deck Resurfacing

If the pool itself is fine but the surrounding deck is cracked, stained, or dated, resurfacing gives the whole backyard a refresh without the cost of a full pool remodel.

Typical cost: $6 – $14 per square foot, depending on the resurfacing material (Kool Deck, cool coat, stamped concrete, pavers, or overlay systems).

Pool Safety Fencing

Required in many cases for code compliance, especially with young kids in the home or on the property.

Typical cost: $18 – $35 per linear foot installed, depending on material (removable mesh, aluminum, or glass panel fencing).
