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

Tree roots don’t necessarily break through concrete on their own, but they can certainly take advantage of existing cracks, even very small ones. As roots grow, they expand the cracks, making them larger and leading to serious and costly foundation damage. It’s a good idea to have repairs on any foundation cracks you’re concerned about.

The best foundation repair method will depend on the issue you’re having, but usually, foundation instability is best fixed using supportive piers, like steel piers or helical piers. A professional foundation repair contractor or structural engineer should always decide what the best course of action is, and even then, it’s imperative that you also take measures to treat the underlying issue as well, like soil erosion or oversaturation from runoff.

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.

The best way to determine if ceiling cracks are structural is to hire a ceiling contractor to inspect the cracks and provide a professional opinion. That said, you might be able to make an educated guess based on the size and appearance of the crack. Larger cracks, cracks accompanied by sagging or discoloration, and cracks that travel from the ceiling down the walls are all signs of structural issues.

The average cost to repair a concrete driveway is between $830 and $2,800, but your costs depend on the extent of the damage. For instance, raising or leveling concrete costs $3 to $25 per square foot, while resurfacing your driveway may cost $3 to $5 per square foot. Meanwhile, small cracks may only cost between $0.10 and $0.15 per linear foot and can be DIYed with synthetic crack filler.
