Common Pool Issues and How We Fix Them For You

backyard of a modern house with swimming pool

A well-maintained pool is the crown jewel of any backyard. But like any structure, it isn’t immune to wear, weather, and time. From murky water to structural cracks, pool problems can show up in a variety of ways. And if left untreated, they can get worse quickly. What starts as a small leak or a cosmetic blemish can lead to major water loss, safety hazards, or even full structural failure.

Whether your pool is a few years old or decades in use, proactive maintenance and timely repairs make all the difference. Green Side Up Contracting combines technical skill with design expertise to fix what’s broken and upgrade what’s outdated. We’ve seen (and solved) nearly every pool issue imaginable.

Here are the most common pool problems homeowners face and how our team steps in to solve them with precision and care.

Cracked Pool Decks or Coping

Concrete decks and coping (the edge between the pool and the deck) can crack due to ground movement, freeze-thaw cycles, or poor initial installation. Left untreated, cracks can expand, create tripping hazards, and allow water infiltration.

Our Fix:

We assess the severity and cause of the cracks before recommending:

  • Concrete patching or resurfacing
  • Pool coping installation
  • Installing expansion joints to prevent future damage
  • Using composite or natural stone overlays for a refreshed look and improved durability

Fading or Peeling Pool Liners

Vinyl liners don’t last forever. Exposure to sun, chemicals, and physical stress can cause them to fade, bubble, or tear, leading to leaks and costly water loss.

Our Fix:

  • Liner inspection to locate damage
  • Custom liner replacement using UV-resistant, high-gauge vinyl
  • Precision measuring and fitting to prevent future slack or bunching

We also offer liner upgrade options for better colour retention and aesthetic appeal.

Pool Water Stains and Discolouration

Rust stains, calcium buildup, and algae can turn a clear pool into an eyesore. Often, stains are the result of metal content in the water, improper chemical balance, or aging pool surfaces.

Our Fix:

  • Chemical balancing and filtration system check
  • Stain removal treatments that target specific mineral or organic buildup
  • Surface refinishing when discolouration is permanent

For long-term prevention, we educate homeowners on proper water testing and offer scheduled pool maintenance services.

Leaking Pool Structures

Leaks can occur from cracks in the pool shell, plumbing issues, or faulty fittings. Even a small leak can waste thousands of litres of water and undermine the surrounding soil.

Our Fix:

  • Leak detection using pressure testing and dye tests
  • Repairing or replacing damaged pipes, jets, or drains
  • Patching structural cracks using epoxy or hydraulic cement

In extreme cases, we may recommend partial pool resurfacing or plumbing rerouting.

Outdated or Inefficient Pool Equipment

Old pumps, filters, and heaters can cause energy waste, poor water quality, and inconsistent temperatures. Equipment over 10 years old is especially prone to inefficiency.

Our Fix:

  • Upgrading to energy-efficient pumps and heaters
  • Installing smart automation systems to control temperature, lights, and water features remotely
  • Replacing worn-out filters and adding UV sanitization for better hygiene

Our goal is to improve functionality while reducing operating costs.

Unsafe or Worn Pool Fencing

Loose panels, broken latches, or outdated designs don’t just look bad; they’re a safety risk. Every pool should have secure, code-compliant fencing.

Our Fix:

  • Fencing repairs to restore integrity and alignment
  • Custom fencing installation using aluminum, wood, or vinyl
  • Ensuring all gates are self-latching and child-safe

We also help clients choose styles that enhance the overall landscape design.

Drainage and Pool Deck Water Issues

Poor drainage around the pool can lead to standing water, slippery surfaces, and erosion. It also encourages algae and mould growth.

Our Fix:

  • Laser-guided grading to redirect runoff
  • Installation of French drains, channel drains, or gravel beds
  • Non-slip coatings and proper slope correction

We prioritize drainage early in any pool deck restoration project to prevent future water-related damage.

Damaged or Uneven Pool Tiles

Tiles can pop off, crack, or become uneven due to ground movement or aging adhesive. Not only does this affect appearance, but it also risks injury.

Our Fix:

  • Tile replacement with modern, slip-resistant options
  • Surface levelling to prevent further shifting
  • Regrouting and waterproof sealing to protect from water infiltration

We can match existing designs or help redesign for a complete style upgrade.

Uninviting Pool Aesthetics

Even if your pool functions well, it might not look appealing. Faded finishes, outdated materials, and poor landscaping can make your pool feel tired and underused.

Our Fix:

  • Pool resurfacing using quartz, pebble, or glass bead finishes
  • Adding waterfalls, LED lighting, or custom features
  • Updatingthe  coping, decks, and landscaping to modern standards

We specialize in pool makeovers that combine form and function.

When to Restore vs. Renovate

If your pool has multiple issues or is over 15–20 years old, it might be time for more than just repairs.

Consider Restoration If:

  • Problems are mostly cosmetic
  • The structure is still sound
  • You want to refresh without major downtime

Consider Renovation If:

  • Structural issues exist
  • The equipment is outdated or broken
  • You want a new layout, features, or functionality

We guide clients through the decision-making process with honest assessments and transparent quotes.
