Winter in New England can be harsh on outdoor structures—but with the right care, your inground gunite pool can emerge from the cold season in excellent condition and ready for another summer of enjoyment. While gunite pools are built for durability and long-term performance, proper winter maintenance is essential for protecting your investment and avoiding costly repairs.

The process begins with properly winterizing your pool—an important step that may require professional assistance to ensure that plumbing, equipment, and surfaces are fully protected. Once your inground gunite pool has been prepped for the off-season, here are some key tips for maintaining it safely and effectively throughout the colder months.

1. Monitor the Pool’s Water Level

Even during the winter, the water levels in your pool can change due to evaporation, leaks, or displacement from heavy snow and ice. For gunite pools, ensuring that the water remains just below the skimmer opening will help counteract soil pressure around the pool, stabilize the shell during freeze–thaw cycles, and prevent structural stress caused by fluctuating groundwater.

Avoid draining the water mid-winter unless directed by a pool professional, as doing so can actually increase the risk of damage.

2. Check the Pool Cover After Storms

Winter storms can place significant strain on pool covers. After heavy snow, ice, or wind, take time to inspect the cover for issues, such as:

• Excessive standing water or snow buildup
• Loose anchors or straps on safety covers
• Sagging areas or visible tears

Addressing small problems like these as soon as possible will help prevent larger issues and keep debris from entering the pool.

3. Keep Debris Off the Cover

Organic debris such as leaves and pine needles doesn’t stop falling just because autumn is over. This debris can add unnecessary weight to your pool cover or even break down and contaminate the water below, which could also stain the gunite surface. Occasional light clearing—particularly after storms—will help preserve both your pool cover and the pool itself.

4. Watch for Signs of Freeze-Thaw Stress

Gunite pools are designed with tensile strength that allows them to flex with the earth, but extreme temperature swings still warrant attention. During winter, keep an eye out for:

• Cracks in the surrounding decking
• Shifting or lifting of coping stones
• Unusual or rapid water loss

If you notice any of these issues, make note of them so they can be properly evaluated when conditions allow.

5. Protect the Area Around the Pool

Winter maintenance isn’t limited to the pool itself—snowmelt and ice can also affect the surrounding landscape and hardscape. Helpful steps include:

• Making sure that downspouts direct water away from the pool
• Preventing ice buildup against coping and tile
• Avoiding the use of harsh de-icing chemicals near the pool deck

Proper drainage helps protect both the gunite shell and the surrounding surfaces.

6. Avoid Walking on the Pool Cover

Unless your pool has a properly installed safety cover designed for weight-bearing, walking on the cover can be dangerous and damaging. Even safety covers should only be accessed when necessary and according to manufacturer guidelines.

If debris removal or inspection feels unsafe, it’s best to contact a professional.

7. Use Winter as a Planning Season

While winter may not be the season for active pool use, it’s an excellent time to plan ahead. For instance, consider:

• Scheduling your spring opening early
• Planning inspections for plaster, tile, and coping
• Budgeting for resurfacing, repairs, or upgrades

Addressing these items early can make your spring pool opening smoother and less stressful.
