Warrantied Foundation Repair in Bethesda

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

To schedule your in-home consultation with a free written estimate, contact us today! We offer our basement waterproofing, crawl space repair and foundation repair services in Bethesda, MD and the surrounding areas.

Noitced a crack in the foundation outside of the home by the patio. Don't know when it appeared there but would like an assessment of what is going on with it and if any repairs are needed.

Two musty crawl spaces, one dirt, one cement.
Project Location: Bethesda, MD
I have a complicated backyard situation that results in water coming into our basement about 3-4 times per year. I believe I will need exterior work and likely installation of a pump to fix the problem. I would like someone to come evaluate my situation and provide an estimate for this work. Thanks.
Project Location: Bethesda, MD
Our late 1950's house has two window wells (same side of house) partially detached from house. The top of the wells are at ground level with no lip. One fills with water during heavy rains and leaks into the basement. So, we might need new or reset window wells, drainage of wells fixed. and sloping of the grade near the problem basement wall so water does not accumulate and leak into the basement.

We have a basement leak and we don't know where it's coming from for sure. Doesn't seem to be plumbing.
Project Location: Bethesda, MD
Hi - we don't have any leaks in our basement where water is visible, but the basement is below ground and there is evidence of previous water and some of the areas of the basement there are large cracks between the wall and floor. This leads to a ton of bugs in our basement. We'd love to have someone come out and let us know what potential options are. Thank you
Project Location: Bethesda, MD
Pooling water from heavy rains around basement window needs to be drained away from the house and the outside waterproofed. Looking to get a quote for this job in a timely manner as we'd like to get moving quickly on this project. Thank you!

Interested in an inspection and proposal to fix foundation walls in my basement with: seeping, mold, hairline cracks
Project Location: Bethesda, MD
We have a small amount of water coming into our basement when it rains very hard.
Project Location: Bethesda, MD
I have 5 vertical cracks in my foundation, visible from the outside because my lot slopes downward from front to back. There is also an area I'd like to ask about where an un-intact cement landing meets the house at ground level.
Project Location: Bethesda, MD
We have water that comes off the street into our driveway and pools around our garage door. This water sits for a while and sometimes enters our garage and also our basement when there is a lot of rain. We are trying to identify a solution so that all this water does not collect in front of our garage and can instead drain somewhere. Look forward to hearing from you! Thanks!
Project Location: Bethesda, MD
I have a downsloping driveway with drain leading to sump pump within the house (utility room) - during deluge of rain - water and silt come up from the sides of the driveway and run into the drain.
