"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."

"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."

"NYC Plumbing, Heating, and Drain Cleaning was hired to clear a main drain blockage. They responded quickly and gave me a reasonable quote. They arrived in a timely manner and resolved the problem within a few minutes. I was informed of the issue and was told that the main drain was snaked out both going into the home and out to the street. I highly recommend them for any drain blockage work you may need."

"Enea and Eres arrived promptly to remove our basement 75gallon leaking water tank and install a new one they brought with them after my frantic early morning call. They installed the new tank, working perfectly, then carried out the extremely heavy old tank up narrow wooden stairs and with heroic effort managed to heave it up and out of the building and arranged for it to be picked up that afternoon Well worth the cost of the job, thoroughly knowledgeable, and prompt service Will call them in future for more home plumbing needs that arise Thank you to AE Mechanical & Heating/Eno Plumbing & Heating for saving the day!!"

Basement Waterproofing questions, answered by experts

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.
