"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 needed to have concrete slabs laid out around my house foundation on exposed grass/dirt areas to drain water away from the foundation as the basement was unreasonably humid during summer months. Kams estimate was reasonable, so I had his crew do the work which occurred over a period of 2 days. I am satisfied with the results."

"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."

"Lazar diagnosed the problem from my description of the problem. He was spot on when he showed up the next day. I wasnâ t on site, he kept me informed at every step, sending video. The main sewer line was clogged, which caused periodic sewerage backups. Compounded by hair in the bathtub, sinks and shower. Within an hour he pulled out tree roots from the line and snaked everything. He then sent pictures of all things flushing and flowing. Extremely professional and reasonably priced. He and his team are plumbing whisperes, excellent technicians."

"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

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

Regular inspections, maintaining proper grading around the foundation, and keeping gutters clear are advisable. Vapor barriers and sealants may need checking for wear after several years.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.
