"Geico Builders and Brian did a fantastic job. He helped us in demolishing a front deck and replacing it with concrete, relocating a tree from the backyard to the front area and assisting with other odds and ends around the house like fixing the lock on the front window, fixing the latch on the entry fence, etc. Geico Builders were professional, courteous, efficient and did great work. Highly recommended."

"I had water damage to the ceiling of my garage. Vicente provided evaluation and written estimate in one visit with attention to details and my customer satisfaction. He took the time to verify my plumbing problem by video taping my water leakage of my bathtub drain pipe with his phone through the broken spaces in the ceiling. He returned the next day with Eduardo, assistant, to complete repair with pipe replacement of old bathtub drain pipes. I was impressed with Vicente's respectful, honest, confident, and professional demeanor with attention to customer satisfaction and service. Vicente exceeded my expectations with exemplary work. Bonus: I discovered afterward that Vicente had fixed my slow flowing sink faucet next to bathtub without request or charge. I would request Vicente again for all my plumbing needs in future. Thank you Vicente. You are special!"

"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)."

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"He was available by phone, and was flexible in scheduling meetings which is great. He was professional, and seemed quite knowledgable. In the end, I didn't use Nato's services because his quote was twice as much as the other contractor I was considering. Perhaps his prices may be more competitive in other services he offers. Either way, working with this company was a pleasant experience."

Basement Waterproofing FAQs, answered by experts

“Basement waterproofing” sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.

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.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.
