⭐⭐⭐⭐⭐
“After years of continuous water seepage in our basement, Roy Johnson Construction installed a drain system that directs water away from our foundation. We recently received 4.5 inches of rain in just one hour — and the system worked perfectly with zero water issues inside or outside the home. We’re extremely pleased with the results!” - Gene L.

This is exactly why proper drainage and waterproofing matters. When extreme weather hits, your home should stay dry and protected. 💪

If you’ve been dealing with basement water, foundation moisture, or drainage issues — we’re here to help.

🛠️ Did You Know? Water Is One of the Biggest Threats to Your Home’s Foundation! 💧

Your home's foundation is literally what everything else rests on, but did you know that excess moisture is one of the most common causes of foundation damage?

🌧️ Here’s how water affects your foundation:

Soil expansion and contraction: When soil gets wet, it swells. When it dries, it shrinks. Over time, this movement puts enormous pressure on your foundation.

Hydrostatic pressure: Water buildup around your foundation walls creates pressure that can cause cracks or even bowing.

Erosion: Poor drainage can wash away the soil that supports your foundation, leading to settling or shifting.

Basement leaks and mold: Cracks and weak points let water seep in, leading to damp basements, musty smells, and harmful mold growth.

🔍 Not sure if your home is at risk? Look for:

Cracks in walls or floors

Doors and windows that stick

Uneven floors

Water stains or damp spots in your basement
