Howard County Waterproofing & Foundation Repair

Basement Waterproofing & Foundation Repair in Howard County

Homes across Howard County face the same forces underground. The county sits in the Maryland Piedmont, with rolling hills, stream valleys and silty clay soil over weathered rock. On sloped lots, rain runs downhill toward foundations, and the clay holds that water against basement walls until it finds a crack, the cove joint or a gap in block. Humid summers and freeze-thaw winters add their own stress to basements and crawl spaces.

I contacted Best Buy Waterproofing through referral. Richard Eagan came out and did a thorough analysis of our basement area letting us know how to best waterproof it through a sub floor pressure release system with a sump pump. He even sat at our table and sketched it out for us to easily digest the process. After a little back... Read More »

Jay Morsberger from Best Buy Waterproofing stood out among several companies that inspected my flooded basement. He explained the source of the problem and what needed to be done with great knowledge and professionalism. His experience gave me confidence, and I knew he was the right person to trust with the job. Thank you, Jay!

Best Buy Waterproofing came quickly to provide a free estimate. Jay came to assess the hole in my basement slab that had a whole with the remains of a basin. He was friendly and provided an honest assessment that I didn't really need their services to just fill the hole. I had not been sure if something... Read More »

I had a great experience with Joe. He is honest, punctual, and answered my questions very patiently. His quality of work is also top-notch! I had three other companies try to upsell services, but Joe’s knowledge and honesty made him and Best Buy easy to trust. I would highly recommend this company, especially because of Joe.

Common Problems in Howard County Homes

Howard County’s hilly terrain, silty clay soil, humid summers and freeze-thaw winters are hard on foundations, basements and crawl spaces. These are the problems we are called about most often.

Wet Basements on Hillside Lots

Rolling terrain sends rain downhill toward foundations on sloped lots. Silty clay drains slowly, so water builds pressure against the wall and pushes through the cove joint, cracks and block cores. Interior drainage with a sump pump relieves that pressure, and French drains can carry surface water away from the house. Basement Waterproofing →

Bowing and Cracked Basement Walls

Clay that swells when wet presses sideways on basement walls, and freeze-thaw winters add stress every year. Horizontal cracks, stair-step cracks and leaning walls are common signs. We stabilize walls with carbon fiber straps or steel I-beam braces, rebuild walls that have moved too far and support settling foundations with piers. Foundation Repair →

Damp, Musty Crawl Spaces

Vented crawl spaces pull in humid summer air, and bare soil adds ground moisture from below. That leads to musty odors, damp insulation and sagging floors. Crawl space encapsulation seals the space with a heavy-duty vapor barrier and a dehumidifier that drains automatically. Crawl Space Repair →

Mold in Basements and Crawl Spaces

Mold follows moisture. We find the source, contain the area, remove the growth with HEPA filtration in place and fix the leak or humidity problem behind it so the mold doesn’t come back. Mold Remediation →

Cold Floors and Drafty Lower Levels

Uninsulated rim joists and basement or crawl space walls let cold air and moisture into your home. Closed-cell spray foam seals those gaps and helps keep the floors above more comfortable through the winter. Spray Foam Insulation →

Why do hillside homes get wet basements?

On a sloped lot, rain and snowmelt run downhill toward the uphill side of the foundation. Howard County’s silty clay soil drains slowly, so that water sits against the wall and pushes through the cove joint, cracks and block walls.

Do I need a permit for waterproofing or foundation repair?

Some projects require a permit and some don’t, depending on the scope of work. When a permit is required, we handle it as part of your project.

Is the inspection really free?

Yes. A specialist inspects your basement, foundation or crawl space, explains what is causing the problem and recommends a solution, with no obligation.
