"The Groundworks folks (formerly Bay Area Underpinning) applied their foundation-underpinning technology and expertise to extend to bedrock, level, square up the foundation for an extensive house remodel. I was most impressed by the young man onsite supervisor, Josh who answered all my work done, how and why questions. I wish this info was provided up front by the estimator. (My design-build remodel contractor referred this company)."

"I am re-landscaping my yard and had used Nato before for a small project and he did a good job for me so I asked him to bid this project. His price was competitive. He and his crew arrived promptly, completed the job on time and did quality work. I installed some irrigation lines and landscape lighting conduit during their job and I was pretty slow and it delayed them from filling in their trenches. Nato and his crew were very patient and Nato actually helped me at one point since I was such rookie. My landscape architect wanted the drains to be done a certain way and while it was not the usual way Nato did drains he was fine doing it the way that was requested. I would definitely use him again and told him to use me as a reference."

"During a house purchase US Trenchless came out and scoped the main sewer line.  They gave me a detailed report.  They also gave me a quote to replace the line.  After doing some comparison shopping US Trenchless beat a competitors low bid by 10%.  The work was done on time and professionally.  I would recommend them and use them again.  Ross and Tim were great."

"Mr. Vince Buggiano was professional, friendly and clearly explained what needed to be done. His crew arrived on time and his staff was careful not to damage my law. After they competed their work they asked for my opinion, making sure I was satisfied. Mr. Buggiano also cut down my neighbors dying 40 year old tree, the tree had been dying for years and large dead branches. His crew tied the branches ensuring they did not damage the house when cut."

"Thanks to Superior.... Jorge, Rudy and David were a great team. They replaced the old cast iron sewer pipe under my building and completed the job in one day. They were very professional and thorough. After, they tested, and everything seems to working fine now."

Basement Waterproofing FAQs, answered by experts

A crawl space encapsulation isn’t always necessary, but it’s a wise choice, especially if you live in an area that sees a lot of precipitation. Sealing a crawl space not only reduces damage caused by moisture, mold, and pests, but it also increases your home’s value. It can also save you money by reducing energy bills and avoiding costly repairs for structural or foundation damage.

Yes, you can enclose your crawl space. Enclosing your crawl space can promote energy efficiency and reduce the risks of pests and mold by limiting factors like humidity. It can also reduce heat loss, which is why doing so for the winter can make your home more comfortable.

Yes, many repair services include reapplying waterproofing and UV-resistant coatings.

Having a trusted crawl space contractor is the key to great encapsulation. If you're not sure how to hire a crawl space pro, begin by asking your neighbors for referrals. Homes in your neighborhood will often have a similar foundation to your house, and personal recommendations are one of the best ways to find a contractor. Additionally, double-check that the contractor has experience with encapsulation as well as proof of their license and insurance.

Periodic inspections and addressing drainage issues prevent further damage.
