Concrete pouring, curbs & gutters, sidewalks, driveways, patios, residential foundations, retaining walls, grinding & cutting.

"Efrain came several times to the property so we could discuss design aspects. He was so patient with me as well as the changes I made each time before I got a quote and he started work. We had a difficult area to have work done in Venice being in the middle of the block and our back alley too small for a standard construction truck to fit. Efrain investigated and figured out the best way to get the excavated soil out as well as the pavers and road base onto the property. Efrain is a man of great character. Once work began, he and his staff were incredibly respectful of our tenants, the property, and our neighbors. He was an artist in several areas, he leveled each and every paver by hand as well as used his expertise in concrete to direct areas for water to drain from the property during rainfall. When I decided to do change orders, he didn’t take that opportunity to charge me a vast amount of money because he knew I had no choice if I wanted the work done. He and his staff always cleaned up after themselves and made sure no one would be in danger of walking across an unsafe area. His work made such a huge difference to the quality and value of the property – it easily paid for itself. If you want an artist who prides himself on his work, Efrain is your guy."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Claremont, CA

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.
