"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."

"Moises and his crew repaired water rotted wood in difficult locations and completely finished the garage to every detail from insulation to molding, as shown in pictures here. They thought of every detail that shows their pride over their work. Not only is their work top notch, but they are also easy to work with and very communicative through the whole process. I have already hired them for a second job."

"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."

"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!!"

"I can't say enough good things about Jimmy- He responded to an emergency sewer backup & when he was here he advised me of the urgent need to replace a VERY old basement slop sink with rotting plumbing (I didn't even realize it) He installed the new sink, reorganized the piping, installed new cutoff valves, changed a bunch of other hoses,etc. He is prompt, courteous, neat & reasonable. What a guy!!!"

"I recently had a roof repair done, and I couldn?t be happier with the results. The team at dryshield arrived on time, were professional, and explained every step of the process in detail. They identified the issue quickly and provided multiple options before deciding on the best fix for my situation. The work was completed efficiently without causing any disruption to my daily life. They cleaned up thoroughly after finishing, and the materials used looked high quality. , and I?ve had no leaks or water damage since the repair. What impressed me most was their attention to detail ? They also offered a clear timeline and kept me updated throughout the process. I would highly recommend them to anyone needing roof repair or replacement. I plan to hire them again for future home improvement projects. Rating: ????? Recommendation: 100% ? I?ll definitely use them again"

Basement Waterproofing FAQs, answered by experts

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.

Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn’t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.
