How to Care for Pool Surfaces When It’s Cold
Chilly weather may not be as extreme in some parts of the country, but even mild winters can do a number on outdoor surfaces if we’re not paying attention. Pool surfaces are no exception. They may not be front of mind during the slower swim months, but they still need some upkeep to stay in good shape. The materials used in custom pools, whether it’s plaster, tile, or pebble, can all react differently when temperatures shift. A little care through winter helps avoid early wear and keeps the pool area looking its best for years to come. In this post, we’re sharing simple ways to handle cold-season upkeep, even when your pool is getting less use.
In places where the weather stays mild but evenings still get chilly, thoughtful features can help. It’s one thing to have a great patio or poolside setup. But if it’s too cold to use it, that space goes to waste half the year. Built-in warmth can change that. When it’s part of the design, it fits better, works better, and gives outdoor living areas a more comfortable feel all winter long.
Cold Weather Effects on Pool Surfaces
Winter weather, even when mild, can still stress pool finishes. Temperature swings, cool mornings, warmer afternoons, then back again, can slowly expand and contract surface materials. Over time, that back-and-forth takes a toll.
• Plaster may develop small cracks or rough spots if the surface dries too much
• Tile lines may loosen slightly or show surface scale when exposed to changing pressure
• Rain followed by when the sun comes back out can leave patches of mineral buildup if not rinsed away
Leaves, dirt, and standing water add to the issue. When debris stays in place for too long, stains can settle into the surface, especially on light-colored finishes. Keep an eye out for signs like flaking, dull patches, or rings that don’t wash off easily. These can be early warnings that surfaces need attention.
Why Water Levels and Chemistry Still Matter
Just because it’s not pool season doesn’t mean the water stops doing its thing. Balanced water chemistry is still one of the best ways to prevent surface trouble.
• Steady water levels reduce the chance of exposed finish areas drying out or cracking
• Keeping pH and calcium levels in the right range can protect grout lines and help tile finishes last
• Even during cooler months, unbalanced water can lead to scaling or surface etching
On custom pools with specialty finishes, chemical swings can have a larger impact. Some finishes react more quickly to pH drops or increases, and ignoring those changes between seasons can shorten the lifespan of the surface. Regular testing during winter, even if it’s just monthly, goes a long way. If levels look off, a light chemical adjustment now can avoid bigger problems come swim season.

Cleaning and Skimming Tips for Low-Use Months
It’s easy to forget about debris when no one is swimming, but regular cleaning still matters. Dirt, leaves, and other yard debris can sit undisturbed for weeks in winter, which makes stains more likely to stick.
• Brushing walls once a week keeps residue from building along the surface
• Skimming the pool after high winds can help control heavier organic materials
• Pool-safe brushes and gentle cleaners are best for delicate surfaces, especially in custom pools
Stains tend to form faster when it’s cold since breakdown happens more slowly. That makes prevention more effective than trying to clean later. Target areas like steps, ledges, or tight corners where debris tends to collect. Choosing soft brushes or rubber-edged tools helps avoid scratching during cleanups.
Using Covers and Heating to Lighten the Load
Pool covers aren’t just about keeping leaves out, they help protect the finishes too. Cold wind, rain, and bright winter sun can wear on the surface if the water is left open to the elements.
• A properly fitted thermal cover can trap heat and shield finishes from daily changes
• Automatic covers make it easy to seal the water off when not in use
• Using low-level heating or gentle water circulation can reduce stress on the surface
Even if the pool is only lightly heated, a small amount of warmth can reduce the internal pressure changes that come from freezing nights and sunny days. For custom-built pools, planning extra care features like integrated covers or wall jets in advance can really simplify winter upkeep. But even with basic materials, smart cover use can add years of life to a pool finish.
