How Expensive to Replace Concrete Around Pool and Redo Plumbing?

If you’re staring at cracked pool decking or dealing with mysterious water loss, you’re probably asking: “How expensive to replace concrete around pool and redo plumbing?” You’re not alone. Many homeowners face this daunting (and costly) decision—especially as aging pools show signs of wear. The good news? With the right info, you can plan smartly, avoid overpaying, and even boost your home’s value. Let’s break down exactly what to expect—cost-wise and process-wise—so you’re never caught off guard.

What Factors Affect the Cost of Replacing Pool Concrete?

The price to replace concrete around a pool isn’t one-size-fits-all. Several variables influence the final bill:

• Size of the deck: Most residential pool decks range from 400 to 1,200 sq. ft. Larger areas = higher material and labor costs.
• Type of concrete: Basic broom-finish concrete costs $6–$10/sq. ft., while stamped or stained concrete can run $12–$25/sq. ft.
• Demolition & disposal: Removing old concrete adds $2–$4/sq. ft.
• Site accessibility: Tight backyards or steep slopes increase labor difficulty (and cost).
• Local labor rates: In high-cost states like California or New York, labor can be 20–30% higher than the national average.

According to the National Association of Home Builders (NAHB), the average cost to replace a pool deck ranges from $4,500 to $15,000, depending on these factors.

💡 Pro Tip: Always get 3+ quotes. Some contractors include demolition; others charge it separately.

How Much Does It Cost to Redo Pool Plumbing?

Pool plumbing repairs or replacements are often hidden—but critical—expenses. Unlike visible deck cracks, plumbing issues may only surface when you notice low water pressure, air in jets, or unexplained water loss.

Common Plumbing Scenarios & Costs:

Most inground pools use PVC pipes buried 18–36 inches underground. Over time, ground shifting, tree roots, or chemical corrosion can cause leaks. If your pool is over 15 years old, plumbing failure becomes more likely.

📌 Expert Insight: “We see 60% of major plumbing failures in pools older than 20 years,” says Marcus Lee, a certified pool contractor with 18 years of experience in Florida. “Don’t wait for a crisis—inspect during routine maintenance.”

For deeper technical background on plumbing materials, Wikipedia’s page on PVC piping explains why it’s the industry standard—and its limitations.

Should You Do Both Projects at Once?

Yes—absolutely. Combining concrete replacement and plumbing work saves significant money and disruption.

Why Bundle the Projects?

• Single excavation: Digging once for plumbing avoids tearing up new concrete later.
• Labor efficiency: Crews can coordinate tasks, reducing total man-hours.
• Permit synergy: Many municipalities allow one permit for related renovations.
• Long-term peace of mind: Fix everything now, not in 2 years.

Homeowners who stagger these projects often pay 15–25% more overall due to duplicated site prep and mobilization fees.

✅ Real Example: In Austin, TX, the Rivera family replaced 800 sq. ft. of cracked deck ($9,200) and redid all underground plumbing ($6,800) together for $14,500. Had they waited, re-breaking the new concrete would’ve added ~$2,200.

Step-by-Step: What to Expect During the Renovation

Here’s a realistic timeline and process if you’re tackling both jobs:

1. Inspection & Design (Days 1–5)
   • Hire a licensed pool contractor + structural engineer (if needed).
   • Use dye tests or pressure tests to locate plumbing leaks.
   • Choose concrete finish (e.g., brushed, stamped, colored).
2. Permitting (Days 5–14)
   • Submit plans to local building department. Most U.S. cities require permits for plumbing and structural changes.
3. Demolition (Day 15)
   • Remove old concrete (typically 1 day for 600–800 sq. ft.).
   • Excavate plumbing trenches (depth: 24–36 inches).
4. Plumbing Work (Days 16–18)
   • Install new Schedule 40 PVC pipes (rated for underground use).
   • Pressure-test system at 50 PSI for 24 hours to confirm no leaks.
5. Concrete Pour (Day 19)
   • Set rebar or fiber mesh for reinforcement.
   • Pour 4-inch-thick concrete with proper slope (1/4″ per foot away from pool).
   • Cure for 7 days before light use; 28 days for full strength.
6. Final Inspection & Cleanup (Day 20–30)
   • City inspector verifies code compliance.
   • Contractor removes debris and seals concrete (optional but recommended).

⚠️ Never skip the pressure test—it’s the only way to guarantee your new plumbing won’t leak under the fresh deck.

Cost-Saving Tips Without Sacrificing Quality

You don’t need to break the bank. Try these vetted strategies:

• Choose basic concrete: Skip decorative finishes unless resale value is a priority. Plain gray lasts just as long.
• Time it right: Schedule in late fall or winter—contractors often offer 10–15% off during slow seasons.
• Reuse existing layout: Avoid redesigning the deck shape; that adds engineering and formwork costs.
• Get material discounts: Ask if your contractor buys in bulk from suppliers like Cemex or Vulcan Materials.

Also, check if your homeowners insurance covers sudden plumbing damage (e.g., from a burst pipe)—though wear-and-tear is usually excluded.

FAQ Section

Q1: How long does a new pool deck last?

A: Properly installed concrete lasts 20–30 years. Sealing every 2–3 years prevents staining and cracking.

Q2: Can I just patch the concrete instead of replacing it?

A: Small cracks (<1/8″) can be sealed, but widespread spalling, heaving, or trip hazards mean full replacement is safer and more cost-effective long-term.

Q3: Will redoing plumbing increase my water bill?

A: Actually, it may lower it! Leaky pipes waste 10–20 gallons/day. New, efficient plumbing reduces waste and pump runtime.

Q4: Do I need to drain the pool for plumbing work?

A: Usually yes—especially if working on main drains or skimmer lines. Draining takes 4–12 hours depending on pool size.

Q5: Are there alternatives to concrete?

A: Yes—pavers ($10–$30/sq. ft.), travertine ($15–$35/sq. ft.), or composite decking ($20–$40/sq. ft.). But concrete remains the most durable and affordable for wet areas.

Q6: How do I find a trustworthy contractor?

A: Check licenses via your state’s contractor board, read Google reviews, and ask for proof of liability insurance. Avoid anyone demanding full payment upfront.

Conclusion

Replacing concrete around your pool and redoing plumbing is a major investment—but one that pays off in safety, aesthetics, and long-term savings. On average, expect to spend $8,000 to $25,000 for both projects combined, depending on scope and location. By bundling the work, choosing practical materials, and hiring vetted professionals, you’ll avoid costly mistakes and enjoy a refreshed backyard oasis for decades.
