Basement waterproofing and foundation repair company. Family owned since 1957 with over 300,000 dry basements. Free consultations. Lifetime warranties available. Award winning company.

"Good work in general; our basement no longer sees water for over 3 years now, which is the most important thing. But there were some real issues: The biggest issue is that USW did not adhere to local electrical codes, and did not arrange for a final inspection of the project. So we didn't find out that it wasn't to code until years later, and now it's a big hassle and minor cost to fix and get the permits. Ask your local gov yourself what you need to do for permits and inspections; don't rely on USW! USW said they would seal any foundation cracks found along the way; they didn't do this until I bugged the warranty dept about it (but they did do it eventually). USW sent someone out for the "annual checkup"... over 2 years after the install. It's a good thing they (eventually) did, because they discovered the backup battery wasn't charging. Now I know to check this stuff better myself. Prices also vary wildly and are kind of negotiable (I'd give more detail but I'm out of space)"

"I recently had the pleasure of working with Juan at J&P Brothers Landscaping to transform my front and side yard, and I couldn’t be happier with the results. From start to finish, Juan and his team demonstrated professionalism, expertise, and a genuine commitment to excellence. 1. Initial Consultation and Proposal: Juan visited my home, took meticulous measurements, and showed me impressive examples of his previous work. He listened attentively to my preferences and needs. Within a week, he provided a detailed proposal that broke down various options, including addressing our backyard landscaping needs. 2. Efficient Execution: After a brief delay due to rain (which Juan communicated promptly), his team efficiently cleared out the yard in just one day. Over the next two days, they laid down approximately 2,500 square feet of lush Kentucky Bluegrass in the front and side yards, as well as the parkway. Juan also addressed a water pooling issue near our foundation—a problem we’d been grappling with for a while. 3. Attention to Detail: Not only did Juan level the problematic area, but he also added a beautiful flower bed according to our agreed-upon plan. Landscape fabric was strategically placed to prevent weeds, and a layer of fresh mulch completed the look. Our neighbors have been giving us glowing complements —the transformation is remarkable! 4. Smooth Process: Juan’s digital contract process made everything hassle-free. I appreciated the transparency and ease of communication throughout the project. 5. Looking Ahead: My wife and I are thrilled with our rejuvenated front yard, and we’re already planning to engage Juan for our backyard landscaping. His expertise and dedication are unmatched. In summary, Juan and his team delivered exceptional results, turning our outdoor space into something truly special. If you’re seeking top-notch landscaping services, look no further—Juan is the real deal!"

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Sandwich, IL

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.
