"Awesome. After many "experts" in waterproofing basements examined my problem, Richie of Mr Brickman Waterproofing examined my water problem even after I had a competitor do faulty work. He diagnosed the problem (a broken pie after careful examination for no fee!!! He also saw the urgency and referred a plumber to stop the water flow into my basement from behind my finished basement wall. His response was immediate and professional and unlike the other professionals he diagnosed the problem correctly and never charged a fee. There are no other contractors I know that would ever extend themselves to that extent. I wholeheartedly recommend this man and trust him with a any/all repairs done in my home!"

"Rahat Construction did an amazing job repairing my basement and waterproofing the exterior of my house after Hurricane Ida. They regraded the cement, replaced the basement doors, re-fortified and repainted the damaged basement walls and replaced the badly cracked cement on my sidewalk. They are highly responsive, they work very quickly and carefully, and above all, they care about their customers—always taking time to explain decisions and new issues as they arise. This is the second time I’ve worked with them, and I would hire them again in a heartbeat."

"I recently had the pleasure of working with Hi Tech Contracting and Restoration Corp for a complete refresh of our home in Queens. Their attention to detail and commitment to quality were evident throughout the project.They expertly performed brick spot pointing on our chimney, repaired our traditional masonry stucco, and applied Thorocoat waterproofing paint on our foundation walls. Additionally, they applied a liquid silicone coating to our flat roof and addressed several issues with our problematic roof.Our neighbor also chose their services, a testament to their outstanding workmanship. I highly recommend Hi Tech Contracting and Restoration Corp for any restoration needs!"

"I hired Long Island handyman construction group to remodel a 400sf basement and bathroom in Melville. They were priced in the middle compared to other bids. I picked them thanks to their out of the box advice which saved me thousands of dollars. There was one problem with the plumbing which cost an extra 1800 dollars. The owner settled with me 50/50 even though it was a pre-existing issue. The project was started early and completed early. All mess was cleaned up and the crew was very friendly and fully aware. Very reputable guys and very easy to deal with. Thanks Moises and Eddy."

"Bobby and his crew answered all my questions, they were respectful and extremely helpful. Bobby and crew went above and beyond what was on the contract. My house looks beautiful, they power washed entire building, pained the sidewall of the building with thorocoat, front of house was pointed where necessary and applied waterproofing sealer, glass block window, painted stoop and stairs, cemented cracks on stoop and sidewalk, painted outside railing and applied cement in basement where needed. I have to say some of what was done wasnâ  t even on the contract, so they went above what was expected and to my surprise Bobby didnâ  t charge extra. Being a single woman who has had bad experiences with contractors and their disgraceful personalities, having Bobby and his crew work on my property was a pleasure and breath of fresh air. I would hire Bobby and his crew again and recommend them in a heart beat. Best work!!"

"Headly was very knowledgeable and professional. He was also very honest to tell me that the issue was not an emergency as I thought it was. He gave me a lot of information about the water in our basement and advised me to call him if it happens again after a heavy rain. He also checked out and cleaned my gutter while he was there."

"Good job but a little bit pricey. Also, I have my water tank replace and he did dispose of the old tank. Not even, bringing it out of the basement for me to put into street curbside for recycling pickup. I have to hire somebody to bring it up from the basement."

"A few months back, my wife and I found Lazer's (owner of NYC Plumbing, Heating and Drain Cleaning) contact info via Google HomeAdvisor as we needed to get a boiler installed, but luckily at that time the boiler company provided free installations - however, we saved Lazer's contact info incase we needed further work. Earlier today, I needed to get an urgent blockage/clog fixed in our basement sink and reached out to Lazer, who was beyond helpful in terms of pricing and availability. He sent one of his workers (Elton) who was not only able to resolve/fix the issue in a matter of mins, but Elton was also kind enough to fix/seal a pipe under the sink which our contractors messed up while installing it. Not only that, but Elton also saw my family and I struggling with a smart thermostat and he went out of his way to help us with the thermostat as well - Jack of all trades!! Lets just say, moving forward I know for sure Lazer and his team will be my go-to people for any plumbing needs. Not only are they fast, helpful and respond right away; but they are very knowledgeable, kind, respectful and very reasonably priced. Overall, amazing work and very reliable!! Highly recommend!!"

Basement Waterproofing FAQs, answered by experts

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

While a standard gutter system is widely considered the most effective way to prevent water damage to your home's foundation, several alternatives are available. These options can be used on their own in certain climates or as supplementary protection.

Common alternatives include:

  • Rain Chains: These are decorative chains that hang from the roof's edge, guiding rainwater to the ground.

  • Drip Edges: These metal strips are installed at the edge of the roof to direct water away from the fascia. While often used with gutters, they can be paired with a ground-level solution but are typically not sufficient on their own.

  • Rain Dispersal Systems: These systems work by breaking up the heavy sheet of water flowing off the roof, dispersing it over a wider area.

  • French Drains: This ground-level system uses a perforated pipe in a gravel-filled trench to collect and redirect water runoff away from the house.

  • Drip Paths: Placed directly below the roofline, these paths made of concrete, stone, or other materials prevent soil erosion and guide water away.

It's important to note that some alternatives like rain chains and dispersal systems may not be adequate in regions with heavy rainfall because they don't divert water away from the foundation as effectively as a full gutter system. Ground-based solutions like French drains can be very effective but are often more expensive and can affect your landscaping and curb appeal. Many experts recommend installing a full gutter system for maximum protection and using alternatives as supplementary measures.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

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.
