Basement Waterproofing Contractors in Glen Burnie, MD
Best Buy Waterproofing provides basement waterproofing in Glen Burnie, MD, for older and newer homes alike. Glen Burnie grew quickly from the 1950s through the 1970s, and a large share of homes from that period were built over block or poured concrete basements. After half a century or more of Maryland weather, those foundations are often where trouble shows up first: a damp strip along the wall after a storm, a musty laundry area or a puddle that appears every spring.
The ground itself is a big part of the story. Northern Anne Arundel County sits on the Atlantic Coastal Plain, where layers of sand and clay lie under the lawn, and the Patapsco River and the creeks that feed the Bay are never far away. In many spots the soil stays wet long after a storm passes, which keeps hydrostatic pressure on basement walls and floors. Our job is to find the exact path the water takes and recommend a repair that stops it for good.
Signs You Need Basement Waterproofing in Glen Burnie

Basement Waterproofing Solutions for Glen Burnie Homes
Interior Drainage and Wall Membranes
For most leaking basements in Glen Burnie, interior drainage is the most practical way to take control of the water. Our crew removes a narrow strip of concrete around the inside edge of the floor, sets perforated pipe in clean gravel beside the footing and runs it to a sump pump. Water that seeps in at the base of the wall, or rises through the joint between wall and floor, is collected and sent outside instead of spreading across the slab.
Block foundations from the 1950s through the 1970s often hold water inside their hollow cores. We add a dimpled membrane to the walls so that moisture drains down behind it into the new system. The trench is then patched with fresh concrete, leaving a clean, dry floor.
Sump Pump Installation and Replacement
A sump pump is the workhorse of most waterproofing systems, and many Glen Burnie basements still rely on a pump that has been running for years. We install new pumps, replace worn or undersized ones and set each pit with a sealed, airtight lid. The lid keeps out debris and basement humidity. A check valve keeps pumped water from flowing back down the line.
Because the strongest storms tend to knock out power, we also offer battery backup pumps and high-water alarms. We direct the discharge line so water is released well away from the foundation instead of soaking right back into the soil beside it.
Exterior Waterproofing
Exterior waterproofing protects the foundation from the outside, so water is stopped before it reaches the wall at all. It can be a good choice when the basement is already finished, when the outside of the wall needs repair, or when the yard leaves enough room to dig along the foundation.
The crew excavates down to the footing, cleans and repairs the wall, then applies a waterproof membrane and drainage board. A new footing drain carries water away, and the soil is backfilled and graded so it slopes away from the house.
French Drains for Soggy Yards
In parts of Glen Burnie, the yard itself stays wet for days after a storm, and low spots near the house send that water straight toward the foundation. When the soil against the wall never gets a chance to dry, the basement keeps paying for it. A French drain intercepts that water in the yard before it builds up against the house.
We dig a trench where the water naturally travels, bed perforated pipe in stone and lead it to a safe outlet. A French drain can work on its own or alongside interior drainage, easing pressure on the wall from both sides.
Sealing Leaking Wall Cracks
When a poured concrete wall has one crack that leaks and the rest of the basement stays dry, a targeted repair may be all you need. We inject the crack with polyurethane, which travels through the full thickness of the wall and stays flexible as the concrete shifts with the seasons. It is a focused form of wet basement repair.
Block walls are different, because water moves through the hollow cores and mortar joints, and sealing one crack usually moves the leak elsewhere. A crack that runs sideways, steps through the mortar or keeps getting wider can also point to a structural problem. In those cases, we talk with you about foundation repair before any waterproofing begins.
Dehumidifiers for Damp Basements
Humid summers near the Bay push moist air into the lower level, where it condenses on cool walls and pipes and leaves that familiar musty smell behind.
We install a commercial-grade basement dehumidifier sized to your space. It drains automatically, so there is no bucket to empty, and it works with your waterproofing system to keep the air in your Glen Burnie basement drier all year.

What Affects the Cost of Basement Waterproofing in Glen Burnie?
We don’t quote basement waterproofing from a price list, because no two Glen Burnie basements take on water the same way. After your free inspection, you get a firm price based on what your home actually needs.
Where Water Enters
A single leaking crack is a smaller job than seepage along several walls.
Basement Perimeter
Longer walls need more drain pipe, membrane and new concrete.
Foundation Type
Block and poured walls leak differently and need different repairs.
Yard Drainage
Soggy, low-lying yards may need a French drain as well as work inside.
Finished Areas
Paneling, drywall or flooring along the walls adds steps to the work.
Added Equipment
Battery backups, alarms and dehumidifiers add protection and change the scope.
Basement Waterproofing FAQs
Why does my Glen Burnie basement stay wet days after it rains?
Glen Burnie sits on layered sandy and clay soils, and many lots are close to the Patapsco River or the creeks that feed the Bay. In those areas the ground can stay saturated well after a storm ends. While it is wet, it keeps pressing water against your foundation, so seepage can continue long after the sky clears.
My house was built in the 1960s. Is that why the basement leaks?
Age plays a role. Many Glen Burnie homes from the 1950s through the 1970s have block or poured walls that have weathered many Maryland winters. Mortar joints wear, small cracks open and original drain tile can clog. A leak in an older home is common, and it is usually very fixable once we find where the water enters.
Will sealing paint on the walls fix my leak?
Usually not for long. Waterproof paint can help with light dampness, but it cannot hold back water that is being pushed through the wall by saturated soil. Managing the water with drainage, a sump pump or a crack injection is a more lasting answer.
Do I need a sump pump if I already have interior drainage?
In most cases, yes. Interior drainage collects water at the base of the wall, but it needs somewhere to go, and a sump pump lifts it out of the basement.
Can you waterproof a basement that is already finished?
Yes. We look at where the water shows up and how the finished walls are built. Sometimes we remove a strip of drywall or paneling along the floor to install interior drainage. In other cases, exterior waterproofing makes more sense because it leaves the finished space alone. We explain the trade-offs before any work begins.
How long does basement waterproofing take?
It depends on the size of your basement and the system it needs. Sealing a single crack is a short visit, while full interior drainage or exterior excavation takes longer. After your free inspection in Glen Burnie, we give you a clear timeline so you know what to expect.
