Baltimore County Basement Waterproofing & Foundation Repair

Basement Waterproofing & Foundation Repair in Baltimore County

Baltimore County wraps around Baltimore City on three sides, but it is its own jurisdiction with its own very different landscapes. In the north and west, around Towson, Pikesville, Owings Mills and Catonsville, homes sit on the hilly Maryland Piedmont, where silty clay soil lies over weathered rock and sloped lots send storm water toward foundations. In the southeast, around Dundalk, Essex and Middle River, the ground is low and flat, with layered sandy and clay soils that stay wet long after a storm.

Best Buy Waterproofing provides basement waterproofing in Baltimore County, along with foundation repair, crawl space repair and the related services older homes often need. Much of the county’s housing dates from the 1920s through the 1960s, from brick rowhouses and duplexes to Cape Cods and ramblers, with newer subdivisions and townhomes farther out, and basements are the norm. Our insured, in-house team has served homeowners since 2017 and is licensed in Maryland, Virginia, Washington DC, Pennsylvania, Delaware and West Virginia. Every project starts with a free inspection, and we are available 24/7.

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 Baltimore County Homes

Hillside runoff in the north, slow-draining low ground in the southeast and a large stock of older foundations make Baltimore County basements work hard. Heavy summer storms, humid air and freeze-thaw winters add to the strain. These are the problems we are called about most.

Runoff and Seepage on Hilly Lots

On the sloped lots common in Towson, Pikesville, Cockeysville and the rest of the northern county, rain flows downhill toward the house, and silty clay soil holds it against the uphill wall. Water then seeps through the cove joint and small cracks. Interior drainage with a sump pump relieves the pressure, and French drains or exterior waterproofing can stop runoff outside. Basement Waterproofing →

Bowing and Cracked Block Walls

Wet clay swells, frozen ground expands, and older block walls take that pressure season after season. Horizontal cracks, stair-step mortar cracks and walls that lean inward are the signs. We secure walls with carbon fiber straps or steel I-beam wall braces, rebuild block walls that have moved too far and support settling sections with push or helical piers. Foundation Repair →

Damp Crawl Spaces on Low Ground

In Dundalk, Essex, Middle River and nearby communities, low ground near the Back River, Middle River and the Chesapeake Bay stays wet for days after heavy rain. Crawl spaces under additions and older homes soak up that moisture, leading to musty odors, rot and sagging floors. Encapsulation with a heavy-duty vapor barrier and a self-draining dehumidifier dries them out. Crawl Space Repair →

Mold in Older Lower Levels

Basements finished long ago, rowhouse basements with little airflow and crawl spaces under additions can all hide mold. We find the source, contain the area, remove the growth with HEPA filtration running and correct the leak or humidity problem behind it, so the mold does not return. Mold Remediation →

Cold Floors and Drafty Rim Joists

Older rowhouses, Cape Cods and ramblers were rarely insulated well at the rim joists or basement walls, so winter air and summer humidity slip right in. Closed-cell spray foam seals those gaps and insulates in one layer, helping the floors above stay warmer and the lower level drier. Spray Foam Insulation →

Baltimore County FAQs

Which parts of Baltimore County do you serve?

We work throughout the county, including Dundalk, Towson, Catonsville, Essex, Woodlawn, Owings Mills, Randallstown, Pikesville, Middle River, Milford Mill, Parkville, Perry Hall, Carney, Reisterstown, Cockeysville, Arbutus, Rosedale and Timonium, plus Lutherville, Garrison, Edgemere, Granite, Hampton and Boring. If your town is not listed, call us to confirm.

Do you also serve Baltimore City?

Yes. Baltimore City is a separate jurisdiction from Baltimore County, even though the county surrounds it on three sides, and we serve homeowners in both. The city has its own service area page with information about its rowhouses and neighborhoods. Many of the same waterproofing and foundation repair methods apply on either side of the line.

Where is your office?

Our office is in Columbia, in neighboring Howard County. We are licensed in Maryland as well as Virginia, Washington DC, Pennsylvania, Delaware and West Virginia. Call (844) 980-3707 or request an estimate online to schedule a free inspection at your Baltimore County home.

Why do so many older Baltimore County basements leak?

A large share of homes here were built between the 1920s and the 1960s, before modern drainage was standard. Original drain tile clogs or collapses, mortar wears down and freeze-thaw winters widen cracks. Add clay soil that holds water and heavy summer storms, and seepage is common. Drainage, sump pumps and crack repair address it.

Do I need a permit for this work?

It depends on the project. When a permit is required, we handle it as part of the job and let you know before work begins, so there is nothing for you to chase down.

Is the inspection free, and do you offer financing?

Yes to both. A specialist inspects your basement, foundation or crawl space, explains what is causing the problem and recommends a solution with no obligation. Financing is available for Baltimore County homeowners who want to spread out the cost.
