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.

You may want to hire a concrete floor contractor to check out your home’s concrete surfaces or inspect your home’s foundation for minor damages that they can fix while on site. They may be able to fix cracks in your driveway or garage floor the same day they fix your concrete steps, as well. General concrete repair experts usually won’t be able to handle larger jobs, like leveling a sunken foundation, so you’ll need to hire a structural engineer for bigger projects.

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.

Always hire a foundation repair contractor the moment you suspect your house doesn't have a good foundation. The longer you wait to address foundation issues, the more likely they can lead to bowing floors, cracks in walls and ceilings, sticking doors and windows, chimney and roof problems, and more. Foundation problems can also let moisture into your home, leading to water damage, mold, and mildew problems.

Barring extreme home foundation problems, most horizontal foundation cracks are fixable using one or more methods. Most of the repair methods require professional expertise to accomplish, and include plate anchors, steel reinforcement, soil anchors, reconstruction, or carbon fiber strip applications. Contacting a professional to diagnose the problem early can minimize repair expenses.
