Water intrusion is one of the most damaging threats to homes in Annapolis, especially for properties near the Severn River, College Creek, or areas with high water tables. From downtown’s historic brick homes to newer builds in neighborhoods like Cape St. Claire and Edgewater, basements in this region face constant pressure from groundwater, seasonal rain, and Maryland’s freeze-thaw cycles.
At ’58 Foundations & Waterproofing, we help Annapolis homeowners protect their homes from below. Our basement waterproofing systems are tailored to the unique soil and weather conditions in Anne Arundel County, so whether you're dealing with leaks, musty odors, or pooling water after storms, we have a solution built to last.

With much of the city sitting near sea level and bordered by the Chesapeake Bay, Annapolis homes are especially vulnerable to high water tables and tidal fluctuations. That constant groundwater pressure creates conditions where water can push through foundation walls and slabs, even without visible cracks.
Rainfall is another major factor. Annapolis averages more than 40 inches of precipitation annually, and with the region’s clay-heavy soil, that water doesn’t drain quickly. Instead, it collects around foundations, saturating the soil and creating hydrostatic pressure that forces moisture through any weak point it can find.
In older neighborhoods like Eastport and the Historic District, many homes were built before modern waterproofing techniques existed. These foundations often lack interior drainage systems or sump pumps. Combine that with aging concrete and poor grading around the home, and you get an environment where water intrusion is just a matter of time.
Winter weather adds yet another layer of risk. During freeze-thaw cycles, the soil around your basement expands and contracts. That movement stresses your foundation walls, widening small fissures that let water in. Even homes that appear structurally sound can fall victim to this cycle if the basement isn’t properly protected.
Musty smells and high humidity
If your basement smells damp or earthy, even when it hasn’t rained, it likely means moisture is seeping through the walls or floor. In historic areas of Annapolis like Murray Hill or Eastport, poor ventilation and porous masonry can trap humidity, allowing mold and mildew to thrive behind the scenes.
White, chalky residue on the basement walls
Efflorescence is a powdery white substance that appears when water evaporates through concrete or brick, leaving behind mineral salts. It’s a clear sign that water is passing through your foundation walls, often due to hydrostatic pressure from Annapolis’s high water table or heavy storms along the Severn River basin.
Damp floors or puddles after rain
Storm runoff that isn’t properly diverted can lead to water pooling along basement walls or soaking through the slab. Homes in low-lying areas of Annapolis often experience water intrusion after summer downpours or sudden snowmelt in early spring.
Cracks in the basement floor or foundation walls
Small cracks may not seem serious, but they can act as entry points for water, especially when the soil around the home expands with moisture. In Annapolis, where red clay soils are common, seasonal shifts can make this worse.
Rust on appliances or storage shelving
If your water heater or basement shelving is showing signs of rust, it’s a warning that excessive moisture is present in the air. Annapolis humidity, especially in unfinished basements, can lead to long-term corrosion and damage.
Bubbling paint or peeling wall coverings
When moisture seeps through basement walls, it can push against the paint or drywall, causing bubbles, blisters, or peeling. This is a cosmetic issue with deeper structural meaning: water is intruding and building up pressure behind the finished surface.

At '58 Foundations & Waterproofing, we offer proven, long-term basement waterproofing solutions tailored for Annapolis homes, from historic row houses in the Historic District to newer builds in Parole and Bay Ridge. Our approach is not one-size-fits-all. We design every system to fit your home’s needs, foundation type, and exposure to Annapolis’s high humidity and storm runoff patterns.
Interior Drain Tile Systems
Installed along the perimeter beneath your basement slab, our drain tile systems relieve hydrostatic pressure and intercept water before it enters. We use 6-inch weep holes, a high-quality drainboard, and fill with pearock to create a path for water to flow directly into a sump pit. Everything is sealed cleanly with new concrete for a finished appearance.
Sump Pumps with Battery Backup Options
Our sump pump systems are the heart of most basement waterproofing jobs. We install durable, high-performance pumps that automatically activate when water levels rise. For added protection during Annapolis’s frequent summer storms, we offer battery backups to keep your system running during power outages.
Basement Wall Liners
For masonry walls that continue to weep water or release vapor after drainage is installed, we add sealed wall liners to capture moisture and direct it into the drain system. They also help brighten the basement and prevent mold or musty odors from forming behind the walls.
Dehumidifier Installation
In basements where humidity is a year-round issue, we install high-capacity dehumidifiers designed to maintain ideal moisture levels automatically. This helps protect belongings, improve air quality, and support healthy conditions throughout the home, especially important in Annapolis’s damp spring and summer seasons.
Yard Drainage Improvements
For homes experiencing surface runoff issues, we offer customized exterior yard drainage solutions. These systems help divert stormwater away from the foundation using French drains, swales, or downspout extensions, helping to reduce long-term hydrostatic pressure against basement walls.
Every solution we install is handled by a Certified Foundation Specialist and backed by our Life-of-the-Structure Warranty. We’ll walk you through exactly what your home needs, with no pressure and no one-size-fits-all fixes.

In Annapolis, where coastal storms, tidal surges, and saturated soil from steady rainfall all put pressure on basement floors and foundations, a reliable sump pump system isn’t optional—it’s essential. Whether your home sits near Spa Creek, backs up to the South River, or rests on one of the city’s many low-lying lots, sump pump failure can lead to sudden, devastating water intrusion.
The right sump pump system doesn’t just handle emergency flooding. It forms the heart of your basement waterproofing solution, removing water quickly, protecting structural integrity, and helping to keep the rest of your system effective. That’s why Annapolis homeowners turn to a basement waterproofing company that understands the region’s unique water risks and builds sump systems that are built to last.
A sump pump system is engineered to collect and redirect groundwater before it ever reaches the surface of your basement. Installed in the lowest point of the foundation, the system activates automatically when rising water is detected.
A fully equipped system typically includes:
Annapolis homes face a complex mix of risks: steady rainfall, high water tables, aging infrastructure, and the threat of hurricane-season downpours. When soil becomes saturated, hydrostatic pressure builds beneath the foundation, seeking any path into the basement. Without a sump pump, even well-drained properties can suffer water damage when storms hit hard.
A professionally installed sump pump system provides:
From Eastport to Admiral Heights, homeowners across Annapolis are investing in sump pump systems not just as flood response tools, but as long-term protection for their homes.
