Basement & Crawl Space Spray Foam in Glen Burnie, MD
Ask the owner of an older Glen Burnie home where the house feels coldest in January, and the answer is usually the floor. Many homes here were built between the 1950s and the 1970s, long before anyone worried much about sealing the foundation. Bare block or concrete walls, rim joists with little or no insulation and drafty crawl spaces let heat slip out all winter. In summer, the same gaps let humid air in, where it condenses on cool masonry and leaves the lower level feeling damp.
Best Buy Waterproofing installs spray foam insulation in Glen Burnie, MD, focused entirely on basements and crawl spaces. We use closed-cell spray foam on basement walls, rim joists and crawl space walls, because it insulates, seals air leaks and resists moisture in one layer. Our in-house team also handles waterproofing and crawl space repair, so we can make sure the space is dry before any foam goes on and plan the work in the right order.

Condensation on Walls
Beads of moisture on concrete or block walls during humid weather.
Drooping Fiberglass
Old batts sagging between joists or lying on the crawl space floor.

Spray Foam Insulation Solutions for Glen Burnie Homes
Basement Wall Insulation
Basement walls stay cool for much of the year, and in a humid Glen Burnie summer that cool surface pulls moisture out of the air. Over time, that condensation leads to damp walls, musty smells and mold behind anything stored against them. Our basement insulation uses closed-cell spray foam applied directly to the block or concrete. It bonds to the wall, acts as a vapor barrier and keeps warm, moist air from ever reaching the cold masonry.
Before we spray anything, we check the walls for cracks and active leaks. Spray foam is not a waterproofing system, so if water is coming through, we explain how our team can stop it first.
Sealing the Rim Joist
The rim joist is the wooden band that sits on top of the foundation wall and wraps around the edge of the house. In many older homes it has a loose piece of fiberglass tucked in place or nothing at all, and outside air leaks in along the sill. Rim joist insulation with closed-cell spray foam fills every uneven pocket between the joists and seals those gaps in a single application.
Sealing the rim joist often makes the floors above feel warmer and cuts down on drafts. It also limits the condensation that can lead to rot along the sill, a common concern in older Glen Burnie houses.
Crawl Space Insulation
Crawl spaces in northern Anne Arundel County sit over soil that often stays damp, and humid summer air only adds to it. Fiberglass in that setting absorbs moisture, sags and stops doing its job. Our approach to crawl space insulation depends on how the space is built. In a vented crawl space, we insulate the floor above and seal the gaps between joists. In a sealed crawl space, we insulate the walls so conditions stay close to those inside your home.
Either way, we use closed-cell spray foam because it resists moisture rather than holding it, and we seal the rim joists around the crawl space at the same time.
Foam Plus Encapsulation
Insulation works best in a space that is already dry. Our crawl space team installs vapor barriers, full encapsulation and commercial-grade dehumidifiers, so we can plan moisture control and insulation together. Encapsulation keeps ground moisture and humid air from building up under the house, while spray foam seals the walls and rim joists around it.
Together, they help reduce dampness, limit heat loss through the floor and make the space less inviting to mold. During the inspection, we tell you whether foam alone will do the job or whether the combined approach is the better fit for your home.
Why Closed-Cell Foam Below Grade
Basements and crawl spaces deal with humidity, condensation and the occasional bit of water, so the insulation has to hold up to all three. Closed-cell spray foam is dense and rigid, and its cells stay sealed. That lets it resist water, act as a vapor barrier and provide strong insulating value for its thickness. It also stays in place without sagging or settling the way batts do in damp spaces.
That is why closed-cell foam is what we install on basement walls, rim joists and crawl space surfaces across Glen Burnie. We do not insulate attics or above-grade walls.

Spray Foam Insulation FAQs
Which parts of my home do you spray foam?
We focus on basements and crawl spaces: basement walls, rim joists, crawl space walls and the floor above vented crawl spaces. Those below-grade areas are where moisture and air leaks usually begin, and closed-cell spray foam handles both. We do not insulate attics or above-grade walls.
Is spray foam a good idea in an older Glen Burnie home?
Often, yes. Many homes in Glen Burnie were built between the 1950s and the 1970s with little insulation at the foundation. Sealing the rim joist and insulating basement or crawl space walls can make a noticeable difference in comfort. We check for moisture first, because older foundations sometimes need waterproofing before insulation.
Can spray foam help lower my energy bills?
Sealing air leaks at the foundation and rim joists reduces how hard your heating and cooling have to work, so many homeowners notice warmer floors and lower energy bills. Results depend on the size and age of the house and the insulation already in place. We point out the biggest leaks during your free inspection.
Will spray foam keep water out of my basement?
No. Spray foam controls air movement and condensation, but it does not stop water that is coming through the walls or floor. If your basement leaks, that needs to be fixed first so the foam does not cover an active problem. Our team also provides basement waterproofing in Glen Burnie, so we can handle both in the right order.
What happens to my old fiberglass insulation?
If it is wet, moldy or sagging, we usually recommend removing it before applying foam. Damp fiberglass holds moisture against the framing and does little to keep heat in. We look at its condition during the inspection and include removal in your recommendation when it is needed.
Is closed-cell foam safe to use in a crawl space?
Closed-cell spray foam is well suited to crawl spaces because it resists moisture instead of absorbing it and stays in place without sagging. We protect nearby surfaces during application and clean up when we finish. If the crawl space is wet, we recommend drying and sealing it first.
