How to Hire a Pools & Spas Contractor

Updated March 2026

Pool and spa contractors design and install in-ground and above-ground swimming pools, hot tubs, and associated equipment including pumps, filters, heaters, and automation systems. In-ground pools are constructed from concrete (gunite/shotcrete), fiberglass, or vinyl liner — each with different cost, longevity, and maintenance profiles. Pool construction is one of the most heavily permitted residential projects, requiring fencing, electrical bonding, and drain safety compliance. Ongoing pool maintenance (chemical balancing, equipment service, winterizing) is essential and many builders offer service contracts. Pool renovations including replastering, retiling, and equipment upgrades extend the life of aging pools.

Typical cost

$25,000 – $80,000per project

Vinyl liner in-ground: $25,000–$45,000. Fiberglass: $30,000–$60,000. Concrete/gunite: $50,000–$100,000+. Hot tub installation: $3,000–$12,000. Annual maintenance: $1,200–$2,400.

Hiring checklist

1Verify the contractor holds a pool contractor license specific to your state.
2Ask for a detailed estimate that separates pool shell, equipment, decking, fencing, and landscaping.
3Confirm all required permits (building, electrical, plumbing, fencing) are included.
4Ask about the warranty on the pool shell, equipment, and workmanship separately.
