"Premier Basement Waterproofing is amazing! My 100 year old basement was musty & damp. I would get inches of water after a rainstorm. Nelson installed a French drain & sump pump which immediately got rid of the water seeping in. He also put up a vapor barrier which has kept my basement dry & no longer musty. My basement is completely water free and it’s been at least 15 months. It’s an amazing difference! I wish the ceiling was higher as it would be a great living space. I would recommend you use Nelson and his team if you want your basement problems to go away! Notice the before & after pictures: "

Four Leaf Restoration, LLC, has over 10 years of experience in the waterproofing and mold industries. We specialize in everything from mold remediation, to sump pump installation, to waterproofing your home. We do not believe that the same company should perform the mold test and abatement, because that is a conflict of interest, We only do what is necessary, not what is profitable. Call us today for a consultation on your project.

"I hired Four Leaf Restoration to install a sump pump system in my dirt floor crawlspace. Mike, the owner, is a consummate professional and very honest and straightforward in communications regarding what needs to be done. He gave me a thorough report and estimate following his inspection. For the work that had to be done, his pricing was very fair. Due to recent storms, he was already fully booked but sent his crew over to start working the following weekend. Those guys did an amazing job: removed all of the tar paper covering the dirt floor and all the insulation overhead so they could inspect thoroughly for any mold due to humidity and any moisture that might have occurred. They sprayed the entire crawlspace in case there was unseen mold, then followed up with a spray mold deterrent. The sump pump and drainage system were installed and the entire floor was covered with a heavy gauge plastic. All new insulation was also installed. The crew dug a french drain out in my yard for the sump pump drain and tied in downspouts on that side to fully divert water away from the house. At the end of each day, they cleaned everything up. They did an amazing job! The man who does my annual termite inspection said he has never been in a crawlspace that is that clean and that actually smells good. Mike also recommended a dehumidifier for the crawlspace for summer months (same one he uses in his home). While he doesn't sell them, he gave me a link to a website and came by to set it up after it arrived. You will not find a more honest or hardworking company than Mike's Four Leaf Restoration. I cannot say enough good things about them. He was referred to me by a co-worker and I am so grateful for that referral!! If have problems with water or mold remediation/restoration in your basement or crawlspace, do not hesitate to call Mike at Four Leaf Restoration."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Sewell, NJ

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
