Why Is Water Pooling Near My Lanai or Foundation?

If you’ve stepped outside after a Tampa Bay storm and spotted puddles around your lanai or foundation, you’re not imagining things — and it’s not just leftover rain. That standing water can slowly stain concrete, soften soil, and even creep toward your home’s base.

At CR Gutters, Inc.™, we see it all the time — a small damp spot that never dries or a puddle that shows up after every rain. It might seem minor, but over time it can cause cracks or moisture under the foundation. The good news? It’s usually an easy fix once you know the cause.

Why Water Collects Near Your Home

Quick answer: Your downspouts might be sending water too close to your home’s slab.

Your gutters do their job — they catch the rain and guide it down the spouts. But if those downspouts stop right at the base of your house, that water ends up soaking into the ground around your foundation. Over time, it wears down the soil, weakens the concrete, and causes water to pool instead of drain.

Tampa Bay’s sandy soil usually drains fast, but even it can only handle so much. During long summer storms, the ground gets saturated, and the extra water starts collecting on the surface. It might not look serious, but that standing water slowly washes away the support under patios and lanais, leading to cracks or uneven settling.

Simple Fixes That Make a Big Difference

Try this: Add 4–6-foot downspout extensions or connect them to underground drainage lines that carry water away safely.

A downspout extension is an easy and affordable way to redirect water just a few feet farther from your home — usually enough to fix the problem. For flatter yards or properties where water tends to gather, underground drainage systems are a more permanent solution. These buried lines collect the runoff and guide it toward the yard, the street, or a drainage basin, keeping the area around your foundation dry.

If you’ve recently added a lanai or patio, check that your gutters were reconnected correctly. Contractors sometimes shorten downspouts or change their slope during construction without realizing it — even a small shift can send gallons of water toward the slab instead of away from it.

Signs It’s Time to Take Action

Stop signs:

• Puddles that hang around long after the rain stops
• Mildew or dark streaks along your lanai
• Small cracks or uneven areas near the foundation
• Soft, washed-out soil near downspouts

It doesn’t take long for water to cause damage in Florida’s humid climate. The sooner you spot and fix it, the easier and cheaper it is to repair.

Typical Costs

Adding downspout extensions usually costs $75–$200 per outlet. For homes needing underground drainage, expect $1,000–$3,000, depending on your yard’s slope and layout.
