Waterproofing & Foundation Services in Owings Mills, MD
Best Buy Waterproofing provides basement waterproofing and foundation repair in Owings Mills for homeowners who have found a damp carpet, a new crack or a musty smell downstairs. Much of the housing here went up between the 1980s and the 2010s, in subdivisions and townhome communities around the Metro subway terminus. Newer does not mean waterproof. Backfill settles, builder drainage clogs, and sloped lots keep sending rain toward the foundation.
Our in-house team handles waterproofing, structural repair, crawl space work, mold remediation, basement finishing and spray foam insulation. We have served homeowners since 2017, we are licensed and insured, and we answer calls 24/7. Every project starts with a free inspection, so you learn what is causing the problem before you commit to anything. Financing is available.

Basement & Foundation Problems We Solve in Owings Mills, MD
Owings Mills sits in the hilly Maryland Piedmont, with silty clay soil over weathered rock and plenty of stream valleys and sloped lots. Heavy summer storms, humid air and freeze-thaw winters test new and older foundations alike.
Leaks in Newer Basements
Many Owings Mills homes were built with a basic footing drain and a single sump pit. Over the years those drains can silt up, downspouts get buried and the soil settles toward the house. Water then finds the cold joint where wall meets floor. Interior drainage feeding a sealed sump pump gives that water a reliable way out. Basement Waterproofing in Owings Mills →
Hillside Runoff and Walkouts
On a sloped lot, the uphill basement wall takes the most water while the walkout side stays dry. Silty clay soaks up rain and holds it against that buried wall. We trace the water’s path, then pair interior drainage with exterior waterproofing or a French drain where grade and access allow. Basement Waterproofing in Owings Mills →
Settling Fill Around Foundations
Soil pushed back around a foundation during construction is looser than the ground beneath it. As it compacts, porches, stoops and corners of a house can drop, and stair-step cracks appear. Push piers and helical piers transfer that load down to firmer soil, and crack repair seals what the movement left behind. Foundation Repair in Owings Mills →
Bowing Basement Walls
Clay that swells when wet and freezes in winter presses sideways on basement walls, especially in older block foundations. A horizontal crack or an inward lean is the early warning. Carbon fiber straps or steel I-beam wall braces secured to the framing stop the movement, and walls pushed too far can be rebuilt. Foundation Repair in Owings Mills →
Damp Crawl Spaces Under Additions
Sunrooms, additions and some older Owings Mills houses sit over shallow crawl spaces with bare dirt and open vents. Humid summer air condenses on the cool framing, bringing musty smells, mold and soft floors. Encapsulation, a dehumidifier and joist repair dry the space out. Crawl Space Repair in Owings Mills →

Owings Mills Basement & Foundation FAQs
My Owings Mills house is less than 30 years old. Why is the basement leaking?
Age is only one factor. Newer homes often rely on a footing drain that clogs over time, and the backfill around the foundation keeps settling for years. On sloped lots that combination sends water straight to the basement wall. Our free inspection pinpoints where the water is entering and why.
Can you waterproof a townhome with shared walls?
Yes. In a townhome we usually work from inside, since digging along a shared wall or a neighbor’s yard is rarely practical. An interior drainage system and sump pump handle the water within your own unit, and we seal cracks along the walls you share.
Do older homes in Owings Mills need different repairs?
Sometimes. Older houses here are more likely to have block foundations, original drain tile and crawl spaces. They can show bowing walls or deteriorated mortar that newer poured walls avoid. We look at how your particular house was built before recommending anything.
Do you offer mold remediation, finishing and spray foam?
Yes. Our same in-house team handles mold remediation, basement finishing and closed-cell spray foam for Owings Mills homeowners. Finishing is available on its own, and we only add waterproofing when the space needs it. Our spray foam work covers basements and crawl spaces.
Are you licensed in Maryland?
Yes. Best Buy Waterproofing is licensed in Maryland as well as Virginia, Washington DC, Pennsylvania, Delaware and West Virginia, and we are fully insured. When a permit is required for your project, we handle it, so you are not left sorting out paperwork while the work is underway.
Does your warranty transfer to a new owner?
Yes. Qualifying work comes with a transferable warranty, so coverage can pass to the next owner if you sell. In a market with plenty of newer homes changing hands, documented repairs can help reassure buyers. We review the warranty details with you before work begins.
