Waterproofing & Foundation Services in Randallstown, MD
Randallstown grew up along Liberty Road, with most of its homes built from the 1960s through the 1980s on rolling ground west of the Baltimore City line toward Liberty Reservoir. Many of those houses are now forty to sixty years old, and the original drain tile, block walls and sump pits are showing their age. Best Buy Waterproofing provides basement waterproofing and foundation repair in Randallstown to keep these homes dry and solid for the next owner.
Split-levels are especially common here, and they come with their own quirks: a lower level partly below grade, a crawl space under part of the house and several places where water can sneak in. Our licensed, insured in-house team has handled all of it since 2017. Every visit starts with a free inspection, we are available 24/7, and financing is available.

Basement & Foundation Problems We Solve in Randallstown, MD
Randallstown’s rolling Piedmont ground has silty clay soil over weathered rock, and on a slope rain naturally drains toward the uphill side of a house. Pair that with homes that have weathered forty or more Maryland winters, and the same few problems show up again and again.
Worn-Out Drain Tile
Homes from the 1960s and 1970s often have original clay or early plastic drain tile around the footing. After forty or fifty years in silty soil, those pipes clog or collapse, and water that once drained away now presses against the wall. A new interior drainage system and sealed sump pump replace that failed system from inside. Basement Waterproofing in Randallstown →
Leaks Into Split-Level Lower Levels
In a split-level, the lower level sits only partly below grade, often with a family room, laundry and a door to the outside. Water tends to enter along the buried walls, at window wells and where the slab meets the block. We track each entry point and combine drainage, crack repair and exterior work as needed.

Bowing Block Walls
Most Randallstown homes of this era have concrete block foundations. Years of clay swelling and freezing against them can push a wall inward, starting with a horizontal crack along a mortar joint. Carbon fiber straps or steel I-beam braces secured to the framing stop the movement, and badly bowed sections can be rebuilt. Foundation Repair in Randallstown →
Settling Garages and Additions
Garages, porches and rear additions were often built later than the house, on shallower footings. When the soil under them shifts, they can drop away from the main structure and leave stair-step cracks behind. Push piers and helical piers reach firmer soil and stop the settling.

Damp Crawl Spaces in Split-Levels
Many split-levels have a crawl space under the main living area. With bare soil and open vents, it collects moisture all summer, which leads to musty kitchens, mold on joists and floors that soften. Encapsulation and a self-draining dehumidifier keep that space dry year round. Crawl Space Repair in Randallstown →

Randallstown Basement & Foundation FAQs
My split-level never leaked before. Why now?
Original drainage wears out. After forty or fifty years, drain tile can clog, sump pumps fail, gutters sag and soil settles toward the house. A long rain that the house once shrugged off can now find its way in. Our free inspection tells you which part of the system has stopped working.
Is a horizontal crack in my block wall serious?
It deserves attention. A horizontal crack in a block foundation usually means soil pressure is pushing the wall inward. Caught early, it can often be stabilized with carbon fiber straps or wall braces. We measure the wall during your inspection and explain the options.
Do you work on both the lower level and the crawl space?
Yes. Many Randallstown split-levels need attention in both places, and one in-house team handles waterproofing, foundation repair and crawl space work. That lets us treat the house as a whole system rather than fixing one area and leaving the other to cause trouble.
Can you update my dated basement once it is dry?
Yes. We offer basement finishing on its own, and it pairs well with waterproofing in older homes. We use moisture-resistant materials and can add egress windows. If the space is already dry, we start the finishing work without adding waterproofing you do not need.
Do you install spray foam in attics?
No. Our closed-cell spray foam work is limited to basements and crawl spaces, where it seals rim joists, insulates foundation walls and resists moisture. In older Randallstown homes, those areas are often where the biggest drafts and coldest floors come from.
What does the transferable warranty mean for me?
Qualifying work comes with a warranty that can pass to the next owner if you sell. In an established community where many homes are changing hands, being able to show documented foundation or waterproofing work can make buyers more comfortable. We review coverage with you before work starts.
