"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."

We specialize in moisture control for crawlspaces and basements. Our team of professionals use the highest quality products and are focused on getting projects done in a timely manner with you, the customer in mind. Vapor barriers Crawlspace encapsulations Dehumidifiers Subfloor insulation Sump pumps and interior drains Fungal treatments Wood repair (moisture and termite damaged)

"Crawlspace Medic - Augusta recently worked on our crawlspace. We were having moisture and water issues, a moisture barrier we previously put in had almost disintegrated, and originally-installed insulation was falling down. Kevin did a thorough inspection and gave me a comprehensive estimate, and his crew arrived timely and went right to work. They constructed a French drain within the crawlspace to drain off any water that would collect under the house, installed new insulation between all floor joists in the crawlspace, and installed a new, white 10-mil vapor barrier throughout the crawlspace. They taped over the seams and spiked the vapor barrier. We had previously installed an exhaust fan. They cleaned up the debris, and the crawlspace looks better than it ever has since we built our home in 1996. They worked continuously and did an excellent job. Tanner was very conscientious and came back to finish up. We are very pleased with the work they did on our home and feel so much better and secure about our crawlspace."

Foundation Repair questions, answered by experts

No, house settling is normal as your home’s foundation settles into the soil below and as the framing of your home shifts as it expands and contracts with changes in temperature and moisture. However, if you get to the point where your doors and windows aren’t opening easily, your floors are uneven, or you can visibly see that your roof line is wavy or uneven, you are more likely to have foundation issues.

Cracks, spalling, uneven surfaces, and weather damage often necessitate professional repair or resurfacing.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

Although it is possible for a house to collapse from a sinking foundation, it will likely take many years, and signs of major issues will be apparent for a while. Homes on hillsides or in areas that experience frequent washouts are at a higher risk of collapse. Still, barring a natural disaster or extreme circumstances, houses are unlikely to fully collapse from foundation damage.

Detailed inspections and tests to determine the extent and cause.
