"Mike Sheehan responded to my inquiry on Angie's List. He came for an estimate on June 11 . The work started on June 27 and was finished on June 28. There were 3 workers working nonstop for 2 days. The old steps were taken off and the stone steps were put on. They really give a new look to the house. My neighbors gave me complements on the work."

"To summarize quickly, I cannot speak highly enough of Diggs Building Technologies. I am absolutely blown away by what they accomplished and would hire them again without hesitation. Worth every penny. For the past 5 years, I have been restoring/rennovating a 1890 Balloon Frame Colonial in Tillson, NY. While the original house foundation was extremely well built and well-mainted, I canâ t say that much about the 2 story enclosed porch put on in the 1920â sâ ¦ The foundation was crumbling; the first floor walls were bowing out and the floor had settled 3+ inches. To further complicate the matter, all the mechnicals of the house (water, sewage, and gas) ran through that back porch foundation making the project extremely complex in scope. Despite these massive issues on the first floor, the 2nd floor of the porch was in great shape and it was important for us to find a builder who could rebuild the entire bottom half of the structure while also preserving the top. This was no small feat. Much to my surprise, Tim and his crew (alongside their engineer) were able to do just that. With precision, they navigated the mechanicals, removed the old foundation and floor and then went on to replace both of those elements. While doing this, the room above stayed untouched. Not one crack on the walls, not one bow in the floor, and shockingly - all 4 of the original casement windows still opened and close. Overall, they did an excellent job and I would hire them without hesitation again. If you are dealing with any foundation issues, I encourage you to hire Tim, Jake, and Jesse. They are the only team I would trust doing this type of work."

"Fausto and his team did an amazing job ripping out old fiberglass and installing new spray in. They also made a custom drywall cover for the exposed pipes. All done in 1.5 days. Less expensive than the comp. Would use again. Great to work with."

Foundation Repair FAQs, answered by experts

Cracks, shifting, or uneven floors indicate potential foundation issues.

Cement companies offer a wide variety of services, including delivering and pouring concrete for home foundations, walkways, patios, driveways, concrete steps, pools, pool decks, and more, plus concrete repair and patching. Most companies also have the ability to demolish and haul away old concrete landscaping features. It’s a good idea to reach out to a few different companies before hiring to make sure you choose one that can tackle the entirety of the project you have from start to finish. This method will typically save you some money over hiring multiple contractors.

It’s crucial to hire a foundation company that’s professional, experienced, and reliable, starting by choosing local experts with at least five to ten years of experience with your type of project. Local foundation companies will understand the soil and weather conditions in your area and can carry out the best solution based on your property characteristics. You should ask for a list of customer references, read through online reviews, and check for customer complaints and unresolved issues filed with the Better Business Bureau (BBB) before hiring.

In order to raise your home to make foundation repairs, you'll need to bring in a structural engineer to help you design the project. You'll also need to see if you're eligible for the permits needed, and contact a foundation repair company near you.

Foundation settlement should be a concern if you notice it happening suddenly and years after construction, if the settlement results in signs of structural damage in your home, or if it happens after a flood, nearby sinkhole, or earthquake. Some signs of severe foundation settlement that should prompt you to call a repair specialist include sloping or uneven floors, large cracks in your foundation, moisture issues or pest infestation in your basement or crawl space, and an uneven roofline.
