Basement, Foundation & Crawl Space Services in Jessup, MD
Jessup spans the Anne Arundel and Howard County line, sitting between Columbia and Fort Meade in the heart of Central Maryland. Our office is in Columbia, so Jessup is part of our home territory, and we know how storms, humid summers and cold winters treat the basements and crawl spaces here. Best Buy Waterproofing provides basement waterproofing in Jessup, along with foundation repair, crawl space repair, mold remediation, basement finishing and spray foam insulation.
Every job is handled by one in-house team rather than a rotating list of subcontractors, so you deal with the same company from the first visit to the last. We are licensed in Maryland, Virginia, Washington DC, Pennsylvania, Delaware and West Virginia, insured, and in business since 2017. Each project starts with a free inspection. We are available 24/7, and financing is available.
Our Services in Jessup
Basement Waterproofing
Water that builds up in the soil after a storm pushes against basement walls and finds every weak spot. Interior waterproofing channels it to a sump pump with a sealed airtight lid, check valve and optional battery backup and high-water alarm. Exterior waterproofing protects the wall from outside, and commercial-grade dehumidifiers that drain automatically control damp air.
Foundation Repair
Clay soil that swells when wet and shrinks when dry puts steady stress on foundations. We stabilize bowing or leaning walls with carbon fiber straps or steel I-beam wall braces, rebuild block walls that have moved too far and seal cracks. When a foundation is settling, push piers or helical piers carry its weight to more stable soil.
Crawl Space Repair
A crawl space with a dirt floor and open vents lets moisture and humid air under the house. Crawl space encapsulation seals the ground and walls with a heavy-duty vapor barrier, closes the vents and adds a dehumidifier that drains automatically. If water pools on the crawl space floor, we add drainage, and we reinforce sagging floors.
Mold Remediation
Where moisture lingers, mold follows. We inspect basements and crawl spaces to find the growth and its cause, contain the work area, run HEPA filtration and remove the mold. Since the same moisture would bring it back, we also repair the leak, drainage issue or humidity problem that started it.

Basement Finishing
A finished basement can become a home office, media room or guest space. We start with a moisture check and recommend waterproofing only if it is needed. From there, our team installs moisture-resistant wall panels, durable flooring and finished ceilings, and egress windows add natural light and a safe exit from the lower level.

Spray Foam Insulation
Closed-cell spray foam on basement walls, rim joists and crawl space walls blocks drafts and outside moisture while it insulates. It helps keep floors above the lower level warmer in winter and limits humid air in summer. We use it only in basements and crawl spaces, often alongside encapsulation or waterproofing work.

Common Basement & Foundation Problems in Jessup, MD
The Anne Arundel side of Jessup sits on the layered sandy and clay soils of the Atlantic Coastal Plain. Heavy summer storms, humid air and freeze-thaw winters test foundations and lower levels throughout the area.
Water Pressure After Storms
During a heavy storm, water fills the soil around the foundation faster than it can drain. That water pushes against the basement walls and floor, a force called hydrostatic pressure, and comes through cracks and the cove joint. Interior drainage with a sump pump relieves the pressure, and exterior waterproofing can block water at the outside. Basement Waterproofing →
Basements That Feel Clammy
Even without visible leaks, a basement can feel damp and smell stale in humid summers. Moisture moves through concrete, and warm air condenses on cool walls and pipes. A commercial-grade dehumidifier that drains automatically, together with closed-cell spray foam on walls and rim joists, keeps humidity in check and protects anything stored downstairs.

Leaning and Bowing Walls
Expanding clay and freeze-thaw cycles press on basement walls from outside. Horizontal cracks, stair-step cracks in block and a wall that tips inward are warning signs. Carbon fiber straps or steel I-beam wall braces stabilize the wall, and if it has moved too far, we rebuild the damaged section so the basement is solid again. Foundation Repair →
Wet Ground Under the House
A vented crawl space with a bare soil floor draws in humid air and ground moisture. Insulation sags, wood gets damp and the floors above can feel soft or cold. Crawl space encapsulation, drainage where water collects and sagging floor repair restore a dry, solid space under the home and make the rooms above more comfortable. Basement Waterproofing →
Mold Behind Stored Items
Boxes against a basement wall, shelving units and unfinished framing all trap moisture and give mold a place to grow out of sight. We contain the area, use HEPA filtration and remove the growth, then fix the moisture source that let it grow. Once the space is dry, it is ready for storage or finishing. Mold Remediation →

Jessup Basement & Foundation FAQs
Do you work on both sides of the county line in Jessup?
Yes. We serve all of Jessup and the 20794 ZIP code, on both the Anne Arundel and Howard County sides. Our Columbia office is close by, and we also serve Columbia, Elkridge, Hanover, Severn, Savage and Laurel. Call us if you would like to confirm that we cover your street.
What should I do if my basement takes on water?
Move valuables off the floor and keep away from water near outlets or appliances. Then call us. We are available 24/7 and can talk through what you are seeing. We then set up an inspection to find out where the water came from and recommend a permanent fix, so it does not happen again.
Do I need a dehumidifier or full waterproofing?
It depends on where the moisture comes from. If water is entering through cracks or the cove joint, you likely need drainage and a sump pump. If the basement is dry underfoot but humid, a commercial-grade dehumidifier may be enough. The free inspection tells us which applies to your home and what we would recommend.
Do you use subcontractors?
No. Our own crew does the work. One in-house team handles waterproofing, foundation repair, crawl space repair, mold remediation, basement finishing and spray foam insulation. That means the company that inspects your Jessup home is the same company that does the work and stands behind it with a transferable warranty.
How much does a typical project cost?
There is no typical price, because every basement and crawl space is different. Size, foundation type, access and the system needed all affect the scope. After a free inspection, we walk you through what we found and what we recommend, then provide a firm price. Financing is available.
Can spray foam go in my crawl space?
Yes. We apply closed-cell spray foam to crawl space walls and rim joists, where it seals air leaks and insulates in one step. It is often paired with encapsulation, so the crawl space stays drier and the floors above feel warmer through the winter. We do not apply it anywhere else in the house.
