Keep Your Home Dry & Structurally Sound
Exterior Drainage & Basement Waterproofing in Decatur, GA
Decatur homes face a combination of conditions that make moisture a persistent challenge. The city's rolling terrain, heavy clay subsoil, and mature tree canopy all work against foundations, and a lot of Decatur's core housing stock, pre-war bungalows across Oakhurst, Winnona Park, and the MAK historic district, plus mid-century block ranches throughout the surrounding DeKalb area, was built long before modern waterproofing was standard. Put those factors together and heavy rain regularly drives surface pooling, foundation seepage, and crawlspace humidity in homes that were never designed to resist it.
APS Waterproofing provides the basement waterproofing and exterior drainage systems Decatur homeowners rely on to keep their foundations dry. Our approach is built around the specific conditions your home faces, not a one-size-fits-all template.
Who We Are
APS Waterproofing is a locally owned company founded by Michael Adams with a clear purpose: help North Georgia homeowners solve moisture problems the right way, the first time. We've built our reputation on honest assessments, quality materials, and systems designed to perform for decades - not just pass inspection.
Decatur holds a special place in our service area. Its mix of historic bungalows, mid-century ranches, and newer infill construction means no two waterproofing projects look the same. We've worked on homes along every type of Decatur street - from tree-lined blocks near the square to hillside lots in unincorporated DeKalb - and we bring that neighborhood-level knowledge to every project.
Why Decatur Homeowners Choose APS Waterproofing
Problem-First Approach
We don't walk in with a pre-set recommendation. We inspect your basement, crawlspace, grading, gutters, and soil conditions to understand exactly where water is entering and why. The solution follows the diagnosis, not the other way around.
Built for Decatur's Terrain and Older Housing Stock
Decatur's mix of varied lot slopes, century-old stone and block foundations, and newer infill construction means every job needs a different plan. We size drainage systems, select membranes, and position discharge points based on your lot's slope, your foundation type, and where water is actually moving on your property, not a template.
Transparent Process
You'll receive a written scope of work, a clear estimate, and a realistic timeline before we start. No hidden fees, no surprise upsells mid-project.
Built to Last
Every component we install. from sump pumps to vapor barriers to drainage piping, is selected for long-term durability in high-moisture environments. We build systems that hold up year after year.
Our Waterproofing & Drainage Services in Decatur
APS Waterproofing offers a full range of waterproofing and moisture control services designed to protect homes from foundation damage and indoor air quality issues.
Basement Waterproofing in Decatur
Basement moisture is a persistent issue across Decatur, especially in older homes where foundation walls have settled and original waterproofing has deteriorated. Water enters through floor-wall joints, hairline cracks, and porous block walls, leading to mold, musty air, and structural weakening over time.
Our basement waterproofing services in Decatur tackle the problem at its source. We install interior perimeter drainage channels, battery-backed sump pump systems, and wall vapor barriers that intercept water before it reaches your living space. For homes with chronic seepage, we combine interior and exterior solutions to create a complete moisture management system.
Exterior Drainage in Decatur
Water that pools around your foundation is water that will eventually find its way inside. Poor grading, clogged gutters, short downspouts, and compacted clay all contribute to drainage failure around Decatur homes.
Our exterior drainage services in Decatur are designed to capture and redirect surface water and subsurface groundwater away from your foundation. We install French drains, catch basins, channel drains, and downspout routing networks customized to your lot's slope, soil type, and water flow patterns. For many Decatur properties, a properly designed exterior drainage system is the single most effective step in preventing basement and crawlspace moisture.
Crawlspace Waterproofing
Most of Decatur's pre-1970s housing stock, especially the bungalows across Oakhurst, Winnona Park, and the intown core, sits on raised brick or block pier foundations with exposed dirt crawlspaces. These spaces act like a moisture reservoir, pulling humidity from the clay soil up through your floors and HVAC returns every warm month.
We install crawlspace drainage systems, heavy-duty moisture barriers, and dehumidification equipment sized for the specific footprint under your home, so the moisture cycle breaks and your floors, joists, and indoor air stay dry.
Crawlspace Encapsulation
For crawlspaces with persistent moisture issues, full encapsulation delivers the most comprehensive protection. A reinforced vapor barrier seals the floor and walls, all vents are closed, and a commercial-grade dehumidifier maintains controlled humidity levels regardless of outdoor conditions.
Encapsulation is especially valuable in Decatur's humid climate, where even homes without active leaks can develop condensation problems in unprotected crawlspaces. Homeowners consistently report improved air quality, lower energy bills, and elimination of musty odors after encapsulation.

Why Decatur Homes Face Elevated Moisture Risk
Several factors make Decatur a particularly challenging area for foundation moisture:
- City of Decatur's pre-war housing stock - Much of Decatur's core was built between 1910 and 1945, when basement waterproofing meant parging the walls and hoping for the best. Those original treatments are long gone, leaving thousands of foundations with no functional barrier against today's rainfall patterns.
- Uphill and hillside lots in unincorporated DeKalb - Unlike the flatter suburbs to the north, DeKalb's rolling terrain means many Decatur homes sit at the bottom of a slope or on a partial daylight basement, with one or two walls pressed against clay that holds moisture far longer than sandier soils.
- Dense mature tree canopy - The tree-lined streets across Oakhurst, Winnona Park, Druid Hills, and the Emory area are beautiful, but the same canopy shades the ground and slows evaporation, keeping soil around foundations damp longer than it would be in more open landscapes.
- Older storm drainage on intown streets - Many intown Decatur streets still drain through decades-old stormwater infrastructure, and even recent street-level upgrades don't address what's happening on private lots where original gutters and downspouts were never sized for today's storms.
- Mid-century block foundations and infill additions - Ranch additions and infill builds from the 1950s through 1980s often sit on block foundations with minimal damp-proofing, which fails predictably once grading shifts or a downspout clogs.
Investing in professional basement waterproofing and exterior drainage is the most reliable way to protect a Decatur home from these ongoing risks.
