Towson, MD Basement Waterproofing & Foundation Repair

Waterproofing & Foundation Services in Towson, MD

Towson is the seat of Baltimore County and home to Towson University and Goucher College, but most residents know it for its tree-lined streets of brick colonials, Tudors and rowhouses. Those homes went up between the 1920s and the 1960s on hilly Piedmont ground, where silty clay over weathered rock holds water and sloped lots steer runoff toward foundations. Best Buy Waterproofing provides basement waterproofing and foundation repair in Towson for homeowners facing seepage, cracked or leaning walls, musty crawl spaces and cold lower levels.

Older masonry basements here have weathered many wet springs and freeze-thaw winters, and newer townhomes are not immune. Our in-house team handles each job from the free inspection to the final cleanup. We have served Maryland homeowners since 2017, we are licensed and insured, and financing is available. Before you commit to anything, we show you where the water or movement is coming from and walk you through what we recommend.

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.

Basement & Foundation Problems We Solve in Towson, MD

Towson sits in the rolling Maryland Piedmont, where silty clay soils over weathered rock drain slowly and many lots slope toward the house. Combine that with heavy summer storms, humid air and freeze-thaw winters, and the masonry basements under a lot of older homes take steady pressure from water and soil.

Runoff From Uphill Lots

On hilly streets, rain from the yard above and from your own roof often heads straight for the foundation. Clay soil soaks it up slowly and holds it against the wall, where it finds the joint at the floor, porous block and old cracks. Interior drainage with a sump pump, or exterior waterproofing where the lot allows digging, gives that water a planned way out. Basement Waterproofing in Towson →

Leaning or Cracked Basement Walls

Wet clay swells and pushes sideways, and each winter freeze adds more strain. In older block basements that shows up as horizontal cracks, stair-step cracks and walls that bow inward. Carbon fiber straps or steel I-beam wall braces, secured top and bottom, can stop the movement, and a section pushed too far can be rebuilt with new block. Foundation Repair in Towson →

Aging Rowhouse and Colonial Basements

Many basements in Towson were built long before modern drainage was common, often with no footing drain or one that clogged long ago. Mortar softens, damp spots spread and the floor stays cool and clammy. A free inspection tells you whether you are dealing with leaks, condensation or both, and which repair actually fits the house. Basement Waterproofing in Towson →

Settling Corners and Sloping Floors

Soil that swings between wet and dry can lose support under part of a footing, especially near downspouts or on the downhill side of a lot. Watch for sticking doors, gaps at window frames and floors that slope. Push piers and helical piers reach firmer soil below and can help lift a settled section back toward level. Foundation Repair in Towson →

Damp Crawl Spaces Under Additions

Plenty of homes here have a crawl space under a family room, sunroom or rear addition. Exposed soil and open vents let humid summer air in, where it condenses on joists and soaks old fiberglass. Encapsulation, a commercial-grade dehumidifier and closed-cell spray foam on the walls and rim joists keep the space drier and the floors above warmer. Crawl Space Repair in Towson →

Towson Basement & Foundation FAQs

Why does water come in on only one side of my Towson basement?

On sloped lots, the uphill wall usually takes the most water because runoff and soil moisture collect against it. Gutters, downspouts and patios that tip toward the house make it worse. During the free inspection we trace where the water enters and look at grading outside, so the fix targets the wall that actually needs it.

Is a horizontal crack in my block wall serious?

It can be. A horizontal crack, especially with an inward bow, usually means soil pressure is pushing the wall. Hairline cracks that are not moving are common, but a bowing wall should be looked at soon. We measure the movement and explain whether carbon fiber straps, steel wall braces or a rebuild makes sense.

Can you work on an older home without damaging the finishes?

Yes. Many homes here have finished basements, plaster walls and established landscaping, and we plan around them. Interior drainage can often be installed along the perimeter with limited disruption, and we protect floors and belongings during the work. We go over access and protection before anything starts.

Are you licensed to work in Baltimore County?

Best Buy Waterproofing is licensed in Maryland (license number 134853) and in Virginia, Washington DC, Pennsylvania, Delaware and West Virginia, and we carry insurance. When a permit is required for your project, we handle it, so you do not have to sort that out yourself.

Do you offer mold remediation and basement finishing in Towson?

Yes. Our same in-house team handles mold remediation and basement finishing for Towson homeowners, and you can read more about both on each service page. Basement finishing is offered on its own, and we only add waterproofing if the basement shows signs that it needs it.

How much will my repair cost?

We do not work from a price list, because foundation type, access, the size of the area and the repair method all vary from home to home. You get a firm price after a free inspection, and financing is available. Our work is backed by a transferable warranty that can pass to the next owner.
