Signs Your Inground Pool Needs Renovation (And What to Do About It)

A well-maintained inground pool can last for decades. But even the best-built pools eventually show their age. Plaster wears down, liners develop tears, pumps burn out, and leaks can quietly waste thousands of gallons of water before anyone notices something is wrong.

If you’ve been putting off pool repairs or wondering whether it’s time for a full renovation, this guide will help you figure out where your pool stands — and what your options are in St. Louis.

Common Signs Your Pool Needs Repair or Renovation

You’re adding water constantly: If you find yourself topping off your pool every few days and evaporation doesn’t explain it, there’s a good chance you have a leak. Pool leaks can originate in the shell, the plumbing, the pump system, or around fittings. Left untreated, even a small leak causes structural damage and drives up your water bill fast.

The surface feels rough underfoot: Pool plaster has a typical lifespan of 7 to 20 years. When it starts to break down, the surface becomes abrasive — uncomfortable on bare feet and hard on swimsuits. It’s also a sign the surface integrity is compromised, which can accelerate further deterioration.

You’re seeing cracks or discoloration: Hairline cracks in the pool shell or floor are worth taking seriously. They can allow water to seep into the surrounding soil, destabilize the structure, and eventually lead to much larger — and more expensive — repairs. Staining and discoloration often indicate mineral buildup, algae, or underlying plaster issues.

Your equipment isn’t keeping up: If your pump struggles to maintain pressure, your filter cycles are off, or your heater is failing to hold temperature, aging equipment is costing you money and shortening your swim season. Modern pump and filtration systems are significantly more energy-efficient than equipment installed even 10 years ago.

The pool just looks dated: Sometimes the pool works fine mechanically but the tile is cracked, the coping is chipped, or the whole thing looks like it was installed in a different era. A cosmetic renovation — new plaster, updated tile, refreshed deck — can completely transform the look and feel of your backyard without a full rebuild.

Pool Repair Services Available in St. Louis

Not every pool problem requires a full renovation. Many issues can be resolved with targeted repairs:

Leak detection and repair involves specialized pressure testing and dye testing to pinpoint exactly where water is escaping — whether it’s in the pool shell, underground plumbing, or around equipment. Catching a leak early saves significant money on water, chemicals, and structural repairs.

Pool resurfacing and replastering addresses surface wear, rough texture, staining, and minor cracking. The process involves draining the pool, removing the damaged plaster layer, preparing the surface, and applying a fresh coat of plaster or a modern aggregate finish.

Tile and coping repair restores the waterline tile and the edging around your pool. These areas see constant water exposure and freeze-thaw stress during St. Louis winters, making them prone to cracking and loosening over time.

Pump, filter, and heater service covers everything from filter media replacement and PVC pipe repairs to full pump and heater swaps. Upgrading to a variable-speed pump alone can cut your pool’s energy consumption dramatically.

Deck refinishing addresses the area surrounding your pool — refinishing worn concrete, repairing cracks, and restoring the non-slip texture that keeps swimmers safe.

When to Renovate vs. When to Repair

This is the question most pool owners struggle with. As a general rule, targeted repairs make sense when you’re dealing with isolated issues — a leaky fitting, worn tile in one section, a failing pump. Renovation makes more sense when multiple systems are failing simultaneously, the surface has deteriorated throughout, or the pool’s overall design no longer suits your needs.

A good pool renovation contractor will give you an honest assessment rather than defaulting to the most expensive option. If a repair will hold for another 10 years, that’s what they should recommend. If the pool has reached the point where repairs are just delaying an inevitable overhaul, they’ll tell you that too.

Frequently Asked Questions

How do I know if my pool has a leak or if it’s just evaporation? 

The bucket test is a simple way to find out. Fill a bucket with pool water, set it on a pool step, and mark the water levels inside and outside the bucket. After 24 hours, if the pool level has dropped more than the bucket level, you likely have a leak. A professional leak detection service can confirm the source.

How long does pool replastering take? 

Most pool replastering projects take 5 to 7 days from draining to refilling, depending on pool size and the extent of surface preparation needed. Your pool will need an additional startup period (typically 1 to 2 weeks) while the plaster cures and water chemistry stabilizes.

How often does an inground pool need to be replastered? 

Standard white plaster typically lasts 7 to 12 years before it needs replacement. Premium aggregate finishes like pebble or quartz can last 15 to 20 years or more with proper water chemistry maintenance.

Can pool leaks be repaired without draining the pool? 

Some leaks — particularly around fittings and returns — can be repaired underwater using specialized injection techniques. Others require draining the pool to access and properly repair the shell or plumbing. Your contractor will assess the best approach based on the leak’s location.

What is pool coping and why does it matter? 

Pool coping is the cap or edging that runs around the top perimeter of the pool shell. It protects the pool structure from water intrusion, provides a finished edge, and creates the transition between the pool and the surrounding deck. Cracked or loose coping can allow water behind the shell and should be repaired promptly.
