Christian Camilo 20 reviews·11 photos 2 minutes ago NEW Positive: Professionalism, Punctuality, Quality, Responsiveness Steve the owner, Tony and Crew @ Blue Umbrella Waterproofing did excellent work. They Truly exceeded my expectation. Steve is extremely customer focused and ensures that his customers have a good understanding of why certain thing need to be done and what they are going to do. The entire process was incredibly smooth, Steve was very detailed in explaining step by step what was happening, he constantly and consistently checked-in to ensure all work passed his quality check. I was impressed by the install, from the scrub down and sanitizing they gave the basement, to the quality of their materials, the additional drain by the door they provided at no extra charge, and last but not least a draining area for the dehumidifier which saves me the twice daily trip down to the basement. I looked at a few waterproofing companies, and am glad I choose Blue Umbrella Waterproofing. They were reliable, efficient, had high-quality standard, and lastly upfront and honest. I would recommend them for any waterproofing needs."

"Full waterproofing of the basement in our 95 year old house, including demolition of walls and shelves/cabinets/sinks and plumbing. Additional service of adding a footing to the basement walls. All the work took three days. Excellent work and looks great, though a bit costly."

"The guys at first choice waterproofing are great. I had them come to my home to try to figure out why I was having water in the basement. Before they came by I had about 5 other companies take a look at the basement to give me their thoughts. No one actually found out what the issue was. First choice was able to diagnose my problem (simply a disconnected furnace tube) and saved me from having to spend thousands to install a new drainage system. I appreciated honesty especially because no one else found it and told me to install a new system. I highly recommend First Choice because they are professionals but above all else they are honest and will give the project the attention it needs."

Basement Waterproofing FAQs, answered by experts

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

A sump pump can remove excess moisture from under a house if standing water is present. Other ways to protect your crawl space from moisture include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home’s foundation can prevent moisture from getting into the crawl space in the first place.

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.
