"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 Hired Hi Tech in spring of 2019 for a repair of my backyard cement work. Kami suggested I replace my cement with pavers instead. His price was so fair, that not only did I hire him to replace my backyard cement, but ALSO repair/waterproof my rear wall AND paint my fire escape as well! I'm so pleased to write that ALL the work Hi Tech did was top-notch & their workers were very respectful and cleaned up very well. Any concerns I had during construction was addressed immediately by Kami, which is HUGE in my book after dealing with other contractors that were not up to par. I would recommend Kami and his workers at Hi Tech Contracting & look forward to using them in the future, because their work raised the value of my home. I now have THE BEST looking backyard on my block!"

"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."

"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 FAQs, answered by experts

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

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.
