"Came out and inspected. Found that my foundation was just fine. Noted a non serious slope in basement slab, but said it could wait a long time. Didn’t need to spend 20-30k on a fix."

"I needed a foundation crack repaired and scheduled for Ram Jack, along with 2 others, for quotes to get that repair done. After receiving a quote from another business, to the tune of $53,000 for "other problems discovered", I had Ram Jack come out and did not tell them what the first place said. After they crawled under the house, took measurements, etc, they found nothing wrong with the foundation, advised me that I was not in need of their services, and provided me with the names of a few well-known and trustworthy local businesses that could repair the foundation crack. I cannot tell you what a relief that was and how impressed I am with the Ram Jack's honesty and integrity! They are definitely on my list of trustworthy people to deal with in the future, if / when needed!"

"4.5 stars overall for removal of concrete slab/stairs and pouring of new 10' long, 4 foot deep foundation wall. Result was excellent. Crew was considerate and trustworthy. It was expensive for me, but cheaper than the other bids I got. Communication was not great over email. There were a number of times I wasn’t replied to at all or got a partial response. I let them know and they said they’ll work on that. I recommend communicating via text instead which worked much better."

"I have a 1906 cottage in N Seattle, with an old porous foundation. Water came into the basement for the first time in 20 years. Another contractor bid the job at $12,000 after 3 site visits and almost a month. Andy came out to the house the same day I talked to him, and estimated the same job at half that price. He followed up with questions, asked about making another visit, came out again and saw that the drainpipe was disconnected at the top of the area being flooded. 75% of the roof's water was pooling against the house. He found a ladder and fixed it and isn't charging me a dime. So, no French drain, no Delta drain, no foundation treatment, no 50' of trenching, no $$$. Andy was timely, reliable, did what he said, and knows his stuff. He was a great communicator, and I feel so so lucky to have found him."

"Insulation Co., LLC did an excellent job in cleaning and repairing our crawlspace. All old, torn and worn-out insulation was replaced, holes and gaps were sealed, and a new vapor barrier was installed. The repaired crawlspace looked like new."

Foundation Repair questions, answered by experts

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

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.

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.

Trenchless sewer replacements are actually a great solution for sewer lines located under concrete. A professional can still sleeve and burst old piping to make room for a new one without having to dig up your slab.

Minor slab leaks normally take around three hours to access and fix, provided the leak is in an accessible location. However, a more extensive leak or a leak in a hard-to-reach location can take several days to fix, depending on the resulting damage. You might also want to consider the timeline for the build-back if the leak damages building materials like flooring or cabinets, which can take several weeks, including delivery of the materials.
