Why Choose Us
Vinyl Liner Replacement
We remove your old liner, inspect the pool structure, and install a new vinyl liner precisely fitted to your pool's dimensions. Every replacement in New Castle County follows our structured process for consistent quality.
What We Offer
Liner Pattern & Finish Selection
Choosing a new liner is an opportunity to refresh your pool's look. We offer a wide selection of patterns, colors, and finishes — from classic solid blues to modern tile and stone prints.
Pool Base & Wall Inspection
A new liner installed over a damaged base won't last. We inspect the pool floor, walls, steps, and fittings before installation to ensure the underlying structure is sound and ready.
Fitting & Gasket Replacement
Skimmer, return, and drain fittings are sealed during liner installation. We replace gaskets and faceplates as needed to prevent leaks at every penetration point.
Liner Care & Maintenance Guidance
After installation, we walk you through proper liner care — including chemical balance, cleaning practices, and winterization steps that help your new liner last as long as possible.
Step & Bench Liner Work
Steps, benches, and other built-in features require careful liner fitting. We custom-fit liner sections around these features to prevent bunching, pulling, and premature wear.

Based on your measurements and preferences, we help you select the right liner and place the order. We confirm lead times and schedule the installation date.
We visit your New Castle County property to assess your existing liner, measure your pool precisely, and discuss pattern and finish options that suit your preferences.

My pool pump died and I called Coastal, instead of my normal pool company, based on some recent warranty work that they had done for me. They were fast, courteous, experienced, and the price was right!

Coastal Pools built our pool 7 years ago and every year it is the highlight of our summer! Our pool is gorgeous and we couldn’t be happier with the service provided as well as the quality of products they used to build it.
