Basement Waterproofing Contractors in Laurel, MD
Best Buy Waterproofing provides basement waterproofing in Laurel, MD for homeowners who want to fix a wet basement for good. Laurel began as a mill town on the Patuxent River, and the ground around it is the same dense silt and clay found across northern Prince George’s County. That soil drains slowly, so after a heavy summer downpour it stays soaked and presses water against foundation walls.
The housing mix in Laurel makes each job a little different. Older homes near the historic core often have block or stone foundations with plenty of mortar joints, while newer townhomes and condos share walls that limit digging outside. Whether you live in Old Town Laurel or Montpelier, our licensed and insured in-house team handles the inspection, the recommendation and the installation. A free inspection shows where the water actually gets in.

Basement Waterproofing Solutions for Laurel Homes
Interior Drainage Systems
An interior drainage system is the workhorse of most basement waterproofing in Laurel. We open a channel along the basement perimeter where the floor meets the walls, lay a perforated drain in clean gravel and restore the floor. Water seeping through the walls or rising under the slab enters the drain and flows to a sump pump. It suits townhomes with shared walls and small yards.
For damp block walls, we can add wall sealing or a wall vapor barrier that guides moisture down into the drain.
Sump Pumps with Battery Backup
A reliable sump pump is what moves collected water out of the house. We set the pit at a low point, connect it to the drainage system and install a pump sized for the water your basement actually sees. Each pit gets a sealed, airtight lid that keeps out debris and humidity, and the discharge line includes a check valve so water does not run back in.
Big storms often knock out power. An optional battery backup takes over automatically when the power drops, and an optional high-water alarm warns you before trouble starts.
French Drains and Footer Drains
A French drain is a perforated pipe bedded in gravel that gives groundwater an easy route away from the house. Inside, it runs around the perimeter and relieves the hydrostatic pressure that builds under the slab when the clay around your Laurel home is saturated. Outside, a footer drain at the base of the foundation walls catches water before it ever reaches the wall.
We route every drain to a sump pump or another suitable discharge point, so collected water does not soak back toward the foundation.
Basement Crack Repair
Freeze-thaw winters and shifting clay soil open cracks in basement walls and floors, and those cracks become direct paths for water. Our basement crack repair seals leaking cracks in poured concrete walls, block walls and floor slabs. In older homes, we also check worn mortar joints.
We check every crack for signs of structural movement. If a crack is tied to a bowing wall or a settling corner, our foundation repair team builds that fix into the same plan.
Exterior Waterproofing and Dehumidifiers
Exterior waterproofing stops water on the outside of the foundation. Our crew excavates along the affected walls to the footing, applies a waterproof membrane, sets a footer drain in gravel and backfills with washed gravel rather than the heavy clay that held water against the wall. It works best on detached homes where there is room to dig.
Even a dry basement can feel muggy in a humid Maryland summer. A commercial-grade basement dehumidifier pulls moisture from the air, drains automatically and helps keep musty odors and mold in check.

Finished Space
Finished walls, flooring or stored belongings may need to be moved or opened.

Cracks and Movement
Leaking cracks or structural movement may need repair alongside the drainage.
Basement Waterproofing FAQs
Why does my Laurel basement only leak after big storms?
Local clay soil absorbs water slowly and holds it. After a heavy storm, the ground next to your foundation becomes saturated, and that water pushes through cracks, mortar joints and the wall-floor seam. In lighter rain the soil keeps up, so the leak seems to disappear until the next downpour.
Is interior or exterior waterproofing better?
Both work when they fit the house. Interior drainage with a sump pump handles water from walls and under the floor and suits townhomes and tight lots. Exterior waterproofing stops water before it touches the wall but needs room to dig. After the free inspection, we recommend the approach that matches your home and the water source.
Can you waterproof a townhome basement with shared walls?
Yes. Many newer Laurel townhomes have shared walls that rule out digging along the side of the house. An interior drainage system works entirely from inside your basement, so it does not depend on your neighbor’s property.
Do I need a battery backup for my sump pump?
It is optional, but strongly worth considering. The storms that bring the most water often cut the power, which is exactly when a standard pump stops. A battery backup takes over automatically, and an optional high-water alarm warns you if the water level climbs.
Will a dehumidifier stop my basement from leaking?
No. A dehumidifier controls moisture in the air, but it cannot keep water from coming through walls or the floor. If we find active leaks, we fix them first with drainage, a sump pump or crack repair. A commercial-grade dehumidifier then handles the humidity that remains during muggy Maryland summers.
