Warrantied Foundation Repair in Fairfax Station

Foundation problems only get worse over time. If you notice cracks in your foundation, basement walls that are bowing or any other sign that something's not right, let one of our foundation specialists take a look - you'll be glad you did. The sooner you take care of your foundation, the less money it will cost you in future repairs.

Some common signs of foundation problems are:

  • Sagging floors and floor cracks
  • Wall cracks
  • Bowing walls
  • Sticking doors and windows
  • Tilting chimneys

With patented helical piers, push piers, wall anchors and crawl space jacks, we can handle any foundation problem. Normal settlement can cause foundation cracks, but they could also mean a serious structural problem.

We never recommend a solution that you don't need. Our goal is to educate you on all the options and let you choose the best solution for your needs and budget

Our painter discovered, after moving some furniture dampness, mold, & mildew in a small area of our basement. After removing some of the drywall there is a hairline crack which is causing the water to leak in. There could be grading concerns causing this....not sure. Will call Friday morning.

Leaking basement in two places. I had a sump pump installed - did not fix. I had the gutters cleaned and enlarged the gutter and downspout in the affected area. I made sure the downspouts drain far away from the foundation. I had the area graded and the outside waterproofed I Installed a plastic corrugated panel under the deck to push any excess water away from the foundation.. It still leaks. I just noticed another small leak for which I have yet to fully investigate.

This is our home we own but have renters in at the moment. They informed us the basement carpet was soaked. It's getting in there by flowing along the wall that is the exterior wall of the house. They indicated they can see the path of water flowing from a corner, moving under the work table and creating a puddle about 7x10. The carpet is toe-squishing soaked, not just a bit wet. We will notify our renters that you will be reaching out to visit the home. The tenants name is Kathy 571-645-6542. We (the homeowners) live in Hong Kong, so we are 12 hours ahead of you. Please also contact us when you receive this to let us know when you will be able to visit the home. Thank you! -Shayna Michael
