"Masle Franciso and his team did some excellent work on my house that needed some floors re-leveled as well as crawl space water proofing. They took the extra time and effort to make sure I was fully satisfied with the job and even added some additional features at no extra cost. Extremely good value for the price I paid, I highly recommend them."

"Eric and his crew tackled a long-standing drainage problem in the basement of our 1932 Craftsman bungalow. We'd had several estimates and options but They impressed us from the start with their solution to the problem and their professionalism. They were great communicators and kept us apprised of what they were doing every step of the way. Can't recommend them enough."

"They had to take out a portion of my front wall which was not planned on, and the conic quality of the concrete was not as good as I thought it should be they destroyed the brick wall that they said they would be able to save and I think they also damaged an additional plumbing line, which I’m going to have to have repaired But we did get the leaking stopped, which was the big part of the problem they had to dig up the entire front foundation down to the 8 foot footer and re-waterproof the wall put in a French drain system and a new drainage system for the gutter and a sump pump"

This can save the homeowner considerable time and money down the road.) 2. Basement waterproofing 3. Foundation crack repair with a lifetime warranty 4. Concrete Lifting and leveling.

Foundation Repair questions, answered by experts

Concrete can crack from general wear, improper installation, or in response to uneven support from the soil underneath. Small, thin cracks on the surface of aging concrete are usually a result of normal wear and tear, while cracks on new concrete more likely indicate a problem with installation. Larger cracks or uneven steps can signify a much more severe issue. A concrete contractor should be able to diagnose the cause and repair concrete cracks for you.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.

Foundation repair costs $250 for a minor crack that doesn’t affect the structure’s integrity, although it can cost as much as $800 if it’s a major crack. Call a pro to get it fixed as soon as possible if your crack is bigger than 1/8 inch wide. Additionally, if you need to seal the foundation to fix leaks, it can cost approximately $2,000 to $7,000.

There are a few ways to reinforce a pier and beam foundation, including installing additional piers and beams for added support and performing underpinning, which redistributes the weight of your home further down into the ground where frost and soil expansion don’t pose a threat to the foundation. The best option for reinforcement varies based on your particular home and the soil conditions beneath it.
