How to Tell If Your Property Has a Drainage Problem

And What You Can Do About It Before It Costs You Thousands

Drainage issues don’t always start with dramatic flooding. In fact, many of the most expensive property damages we see at GRCo LLC start quietly—under the surface, behind the walls, or after one too many “small puddles” are ignored.

If you're a property owner, HOA board member, or property manager, here are the early warning signs that your drainage system may not be doing its job—and why acting fast can save you money, time, and serious stress.

1. Standing Water That Doesn’t Drain

If you notice water pooling around your lawn, sidewalks, or foundation after it rains—and it’s still there hours or days later—that’s a red flag. Water should be flowing away from your property, not collecting near it.

Left untreated, standing water can:

• Erode soil and mulch

• Attract mosquitoes and pests

• Weaken foundations

• Create slip hazards

  
  

2. Soggy or Uneven Ground

Even if you don’t see water, soft, mushy ground—especially on slopes or around walkways—is often a sign of water collecting below the surface. This usually means the soil is oversaturated and drainage isn’t working properly.

3. Water Stains or Mold Around the Base of Buildings

Look closely at retaining walls, siding, or garage walls. If you see discoloration, mildew, or a damp smell, it's likely that water is pooling up against your structures. Over time, this leads to rot, cracked foundations, and mold issues that can be expensive to remediate.

4. Gutter Overflow or Downspouts Dumping Water

Drainage issues sometimes start up high. If your gutters overflow or your downspouts release water too close to your home, it can lead to erosion around your foundation and backflow toward the structure.

A proper system should include downspout extensions, drains, or swales to carry water away effectively.

5. Cracking Sidewalks or Shifting Retaining Walls

Water that isn’t managed properly weakens the ground underneath concrete paths, patios, and walls. If you're seeing cracks, tilting, or sinking in these structures, drainage might be the hidden culprit.

Why It Matters

Unchecked drainage problems lead to:

• Foundation damage

• Erosion control violations (especially for HOAs)

• Landscape deterioration

• Costly repairs

  
  

What starts as a simple water issue can evolve into a major liability if not addressed professionally.
