The Sunshine Waterproofing way
Most wet-basement calls don’t need a sales pitch. They need someone who can read the water.
We start with a real inspection: where water enters, how it travels, what the soil and grade are doing outside. Then we explain it in plain English and build a plan around your home, not a template.

View all servicesFree inspection
We walk the basement, crawl space, foundation, window wells, pump setup and exterior drainage. We take photos. We listen.
Plain-English diagnosis
We show you what we found, where the water is starting, and the options that actually make sense for your home.
Custom water plan
Every plan is built around your foundation, finished space and how you use the basement, never a one-size-fits-all template.
Clean install & follow-up
We protect the home during the work, leave it tidy, and walk you through the system so you know what to expect after storms.
From recent projects
Drainage, pumps, crawl spaces and window wells, all working together.
Most homes don’t have one water problem. They have a few small ones adding up. Here’s a look at how the pieces fit together.
