My experience with Bel Air Waterproofing was superb. I needed my crawl space under my bedroom redone, insulation was falling down & the plastic on ground was cheap & torn. I was presented with options & costs, I was not pressured either way. I went with the more expensive vapor barrier to prevent moisture & possible mildew & mold, very important to me since I have asthma.
Katie & Jeremy were under there (in the heat!) for several days getting the insulation back up, using plastic sheets & wood pieces to make it much more secure than it was originally & then laid the vapor barrier. The entire crawl space looked great when they finished & was certainly a relief to not have to worry about moisture & its effects on my home & health.
I highly recommend Bel Air Waterproofing for any type of job. They pay attention to detail.

Called Bel Air Water proofing. Talk to the owner Katie, and she came out and did an estimate next day. A week later the installers Jeremy and Steve came out and installed a partial french drain system. Couldn't be happier with the work, the professionalism, and just all the around experience was stress free.
Frequently Asked Questions About Bel Air Waterproofing, Inc.
What are the signs that I need basement waterproofing?
Typical indicators include water stains appearing on walls or floors, musty smells, visible mold, excessive dampness, cracks in your foundation, and pooling water following periods of heavy rainfall. Waterproofing your basement protects your foundation, enhances indoor air quality, and helps you avoid expensive water-related damage.
How does a French drain help prevent basement flooding?
A French drain is a trench-style drainage system that collects groundwater and channels it away from your foundation. By lowering water pressure surrounding the foundation, French drains effectively prevent basement leaks, flooding, and problems associated with excess moisture.
When should foundation cracks be repaired?
Foundation cracks should be evaluated immediately upon discovery. Even minor cracks can permit water entry, while more significant cracks may signal structural issues. Timely foundation repair prevents additional damage and maintains your home's structural integrity.
What is mold remediation, and why is it important?
Mold remediation involves identifying, eliminating, and preventing mold within your property. Mold compromises indoor air quality and may present health risks. Professional remediation services address moisture sources and help establish a healthier living environment.
What does a sump pump do?
A sump pump extracts excess groundwater from the area surrounding your foundation and channels it safely away from your home. It's among the most reliable methods for preventing basement flooding and water damage, particularly during Maryland's intense storms.
Why should I consider a sump pump battery backup?
A battery backup for your sump pump delivers protection when power outages occur. Should severe weather knock out your electricity, the backup system ensures your sump pump continues functioning to help prevent flooding during critical times.
What is a water-powered sump pump backup system?
A water-powered backup sump pump utilizes your home's municipal water pressure to discharge water when your primary sump pump malfunctions or loses power. It offers an extra level of security for homeowners who want dependable flood protection.
How can underground downspout extensions help protect my property?
Underground downspout extensions transport rainwater away from your foundation, minimizing the chance of water accumulating near your home. This approach helps prevent basement leaks, foundation deterioration, soil erosion, and standing water in your yard.
What are storm drains, channel drains, and retention ponds used for?
These drainage systems manage excess surface water and minimize flooding risks:
Storm drains gather and divert runoff from properties and paved areas.
External channel drains intercept water before it reaches garages, patios, driveways, or foundations.
Retention ponds temporarily hold stormwater and release it slowly to prevent flooding and erosion.
Do you offer additional property drainage and site services?
Yes. Bel Air Waterproofing provides a comprehensive range of services extending beyond waterproofing, including concrete work, grading and excavation, snow removal, drainage system installation, foundation repair, mold remediation, and stormwater management. These services help property owners protect their investments from water damage throughout the year.
