Pool Construction and Installation questions, answered by experts

Your pool enclosure’s lifespan will depend on the type and materials, but on average, you can expect it to last 10 to 15 years. The climate and level of maintenance will also affect how long your pool enclosure lasts. 

If you’re unsure of how your pool is doing in general, you can always get a pool inspection to make sure everything’s running smoothly.

If you don’t have the budget for one, there are numerous ways to warm up your pool without a heater. You can improve the insulation, use solar covers to trap heat from the sun, or even let a black hose sit in the sun until it heats up and delivers fresh, warm water straight to your pool.

Small animals, particularly rats and mice, like to burrow inside pool heaters. To keep them out, seal any entry points with caulk or steel wool. Then, place mothballs inside or around your pool heater. As a final measure of protection, you can cover the pool heater in hardware cloth or wood paneling to further block entry points.

Using a gas pool heater is the fastest way to heat an outdoor pool. Gas pool heaters are powerful and can increase pool water temperature by 1 to 3 degrees Fahrenheit per hour. Using a gas pool heater and a solar pool cover will get your pool warm as fast as possible.

If you have multiple rooms that could use some organization, home storage solutions like cubbies in your mudroom or built-in shelving can help you move clutter off the floor. Take it one step further by pairing shelves and cabinets with personalized aesthetic touches like woven or canvas lined metal baskets to add another organizational element.
