"Jason from Quacker's arrived ON TIME to repair the foundation crack. He took a look at it, and told me that it was a minor crack. Jason told me to go to the hardware store and buy a $5.00 tube of caulk and seal it up myself. Instead of charging me for a professional repair that I didn't need, he TOLD ME THE TRUTH and saved me a ton of money! Quacker's has earned my trust. If I need any of the services that they offer, I *will* call them again!"

"

I don't recall the date this occurred, but it was not July 2015, but the format requires a date.  In any event, I was concerned about a foundation problem, and Roberts sent a representative out who inspected inside and outside and advised that while he would love to have found a problem that would have involved an expensive repair, he could not do so because he saw no foundation problem.  He was as honest as the day is long, extraordinarily polite and gave considerable supporting statements as to his determination.  I really appreciated his integrity.

"I was very fortunate to have High & Dry to tackle couple of cracks that used to leak water whenever it rains. These cracks repaired couple years ago. So far I had No water leaking whatsoever. Job well done. Company you depend on. Fast, clean, reasonable. I’m a customer for life. I normally don’t write a bunch of reviews generally speaking. I had to leave thumbs up for their work. A BBB rating and been in business for over a decade."

"Finish Touch gets 5 stars from me. They built us a beautiful looking retaining wall at the rear of our house 4 years ago this month and were the low bidder by far--the bids ranged from over $17,000 to under $3000 for Finishing Touch with several others from 6k to 10k. I waited to post a review until now because build quality of a retaining wall can't be measured until after passage of time. Their wall has held up nearly perfectly over 4 years now so I believe it is justifiable to say it was properly built and the preparatory pre-construction work like ensuring drainage was all done well. On top of doing first rate work at the low price, a few months ago I contacted Mr. Watson about another potential job involving our crumbling and sagging concrete front steps and porch. He spent a good 20 minutes+ explaining we could get 90% of the benefit of redoing them by instead mud jacking them and using polymeric sand to fill a crack. He was right. I unreservedly recommend them."

Foundation Repair FAQs, answered by experts

Minor hairline cracks in your concrete may not look pretty, but they’re often not serious. It’s when concrete cracks are larger—wide enough that you can slide a credit card into it—that you need to worry. If you monitor a crack and can trace its active expansion over time, you’ll definitely want to call in a pro to inspect it and, potentially, repair it. Want to prevent cracks in your garage and driveway concrete in the future? Stay on top of sealing. Here’s how to seal your concrete garage floor and driveway.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

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.

If your building department catches you or a contractor doing foundation work without proper permits, they will likely put the work on hold until you secure the necessary permits, which can cause delays of days or even weeks. You can also face violation charges for construction without a permit, which can cost hundreds, depending on where you live.

You can use a level or straight-edge to test for plumb foundation walls and a level slab, a level or a ball to check for sloping floors inside your home, and a hygrometer to look for moisture in your underhome area. Aside from these DIY tests, it’s important to get a foundation repair specialist or structural engineer to test the foundation to see if it’s supporting your structure properly. They can determine if the loads on the concrete are uneven or need reinforcement.
