Waterproofing & Foundation Services in Hanover, MD
Hanover has grown quickly around BWI Airport and Arundel Mills, and much of its housing is newer construction, including many townhome communities. A newer home is not immune to water, though. Backfill around the foundation keeps settling for years, grading can shift, and a builder-installed sump pump may not keep up with a heavy storm. Best Buy Waterproofing offers basement waterproofing in Hanover, plus foundation repair, crawl space repair, basement finishing and more.
Hanover spans the Anne Arundel and Howard County line, and our Columbia office is close by. One in-house team does every job. We are licensed in Maryland, Virginia, Washington DC, Pennsylvania, Delaware and West Virginia, insured, and in business since 2017. Every project starts with a free inspection, we are available 24/7, and financing is available.
Our Services in Hanover
Basement Waterproofing
Even a newer basement can leak through tie holes, pipe openings or the joint where wall and floor meet. Interior waterproofing captures water at the perimeter and routes it to a sump pump with a sealed airtight lid, check valve and optional battery backup. Exterior waterproofing and French drains handle water outside the foundation when the lot calls for it.
Foundation Repair
Fill soil placed during construction can compact unevenly, and wet clay can press on basement walls. We seal cracks in poured walls, stabilize walls with carbon fiber straps or steel I-beam wall braces, and rebuild block walls that have moved too far. Push piers and helical piers support settling foundations by reaching stable soil below the fill.
Crawl Space Repair
Not every Hanover house has a full basement. Older homes and some additions sit over crawl spaces that collect humid air and ground moisture. Crawl space encapsulation covers the ground and walls with a heavy-duty vapor barrier, seals the vents and adds a dehumidifier that drains automatically. We also waterproof crawl spaces and repair sagging floors.
Mold Remediation
Mold can start behind drywall or under carpet in a finished lower level, often long before anyone sees it. We inspect to locate the growth and the moisture causing it, set up containment and HEPA filtration, and remove the mold. Then we repair the source so the problem does not keep coming back.

Basement Finishing
In a townhome, the basement is often the easiest place to gain living space. We check it for moisture first and recommend waterproofing only if it is needed. Our team then builds out the room with moisture-resistant wall panels, durable flooring and finished ceilings, and egress windows can add daylight and a safe exit where the layout allows.

Spray Foam Insulation
Closed-cell spray foam seals air gaps and insulates in one step. We apply it to basement walls, rim joists and crawl space walls, which helps a lower level stay warmer in winter and less humid in summer. It is a good step before finishing a basement, since it keeps outside moisture from reaching the new walls.

Basement & Foundation Problems We Solve in Hanover, MD
Hanover sits on layered sandy and clay soils typical of this part of Central Maryland. Heavy summer storms, humid air and freeze-thaw winters affect new and older foundations alike.
Settling Backfill Around New Homes
When a house is built, soil is dug out and later pushed back around the foundation. That backfill is looser than undisturbed ground and keeps compacting, which can create low spots that send water toward the wall. Interior drainage handles water that reaches the basement, and French drains can redirect it in the yard. Foundation Repair →
Leaks at Tie Holes and Pipes
Poured concrete walls have small tie holes from the forms, plus openings where pipes and utility lines pass through. These spots can seep after a heavy rain, even in a fairly new basement. Crack repair seals the openings, and interior waterproofing with a sump pump relieves the water pressure behind the wall. Basement Waterproofing →
Sump Pumps That Fall Behind
A builder-grade pump with an open pit may struggle in a big storm or fail without warning. An open pit also lets damp air into the basement. We install sump pumps with sealed airtight lids and check valves, with optional battery backup and high-water alarms for added peace of mind. Basement Waterproofing →
Shrinkage and Settlement Cracks
Thin vertical cracks often appear in poured walls as the concrete cures, and they can let water in. Wider cracks, sticking doors or sloping floors may point to settlement instead. We seal leaking cracks, and if the foundation is moving, push piers or helical piers bring support down to stable soil. Foundation Repair →
Damp Townhome Basements
Shared walls and below-grade space can leave a townhome basement feeling clammy, especially in humid summers. Condensation on walls and a musty smell are early signs. Commercial-grade dehumidifiers that drain automatically, closed-cell spray foam on walls and rim joists, and waterproofing where needed keep the space dry enough to use. Basement Waterproofing →

Hanover Basement & Foundation FAQs
Do you serve both the Anne Arundel and Howard County sides of Hanover?
Yes. We serve Hanover and the 21076 ZIP code on both sides of the county line, along with Severn, Glen Burnie, Linthicum, Jessup, Elkridge and Odenton. Our Columbia office is close by. If you want to confirm we cover your address, give us a call.
My home is only a few years old. Why is the basement wet?
Newer homes often sit on backfill that is still settling, and that can change how water drains around the house. Tie holes, pipe openings and small shrinkage cracks can also let water in. A free inspection shows where the water is coming from and which fix makes sense.
Should I waterproof before finishing my townhome basement?
Only if it needs it. We check the basement for moisture before any finishing work. If we find signs of water, we take care of that first so the new space stays dry. If the basement is already dry, we move straight to wall panels, flooring, ceilings and egress windows.
Can you add a battery backup to my existing sump pump?
We can look at your current setup during the inspection. In many cases the best option is a new system with a sealed airtight lid, check valve and battery backup, plus a high-water alarm if you want one. We explain the choices so you can decide what fits your home.
How do you price waterproofing and foundation work?
We do not quote from a price list. The size of the basement or crawl space, foundation type, access and the system needed all affect cost. After a free inspection we walk you through what we found and what we recommend, then provide a firm price. Financing is available.
Is your work covered by a warranty?
Yes. Qualifying work comes with a transferable warranty, so if you sell your Hanover home, coverage can pass to the next owner. We review what the warranty covers before work starts. That can also be helpful to share with buyers who ask about the basement.
