Our trained technicians provide you with a comprehensive analysis of what's causing your basement water problem, and the proper solution to solve it once and for all.

Foundation & Structural Repair in Chantilly

Wall Anchor System Installed

Wall anchors hold back bowing walls to keep your home stable.

If you have 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 problem, the less money it will cost you in future repairs. 

We offer a full range of foundation repair solutions in Chantilly, including 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.

Common signs of foundation problems are:

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

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.

Basement waterproofing
Project Location: Chantilly, VA
Hello! We've recently experienced some water leaking in the basement due to heavy rain. I would like to find out the root cause of the water leak, weather it is related to potentially sump pump malfunctioning that caused overflow of water, water piping and/or drainage issue that require some waterproofing work. Thank you!
Project Location: Chantilly, VA
We have had trace amounts of moisture come in near the basement walkout door. We have been told that corner of the house has settled an inch.

We have a crawl space that hasn't been properly taken care of and would like a quote on how much it would be to take care of it.

Foundation repair estimate
Project Location: Chantilly, VA
Our home was built in 2004, and we purchased it in 2017. Since moving into this home, we have noticed some signs that we may have some structural issues and would like a professional review and discussion on whether these issues should be of concern, or if they are a normally part of the home settling over time. We have noticed the following: 1: Small cracks in the garage concrete floor and bowed walls. 2: Sinking in the driveway, near where the garage meets the driveway 3: Cracks in exterior wall underneath the garage and underneath the deck 4: Sagging and separating of the siding near one of our rooms, that is over the side entry to the home 5: Bowed truss in the attic dormer space. 6: Sidewalk sinking and cracks in brickwork at Side Porch Steps and front walkway. We would like a professional evaluation and recommendations associated with these concerns at the earliest possible date.

Problem started this year....when we get heavy rain, we get a leak in basement that we believe originates behind a finished bath in basement (we have a full bath in basement, but, other than that, basement is unfinished)....water accumulates on floor in finished bath.....can also see wetness on bottom of basement wall just to the right side wall of finished bath... We think that there is some type of leak behind the right side of the finished bath....water comes down under cabinet below sink and seeps out from under cabinet and pools on floor next to toilet...

Some areas around the house seem to be sinking. Noticed some cracks on concrete.

I have found out there is a crack on the concrete wall in the basement because water was leaking. I would like a professional to come in and check and give an estimate. Also, I would like to get this fixed as soon as possible, so sooner the better. Prefer to communicate through email and text. Thank you for your time! Royce

Basement Crack Sealing

I believe I have a crack in the basement wall. Has been leaking small amounts of water onto finished area (carpet / padding / baseboard). Had a similar crack sealed ~5 years ago, 2-3 feet to the left of where I suspect the problem is now.
