"Tim, Jake and Jesse were phenomenal to work with! They performed structural repair to the box beam and main beam. They showed up early everyday and worked diligently to finish the job to a high quality standard. Their customer service and reliability can't be beat. I would recommend Diggs to anyone with foundational repair needs!"

Customers say: Quick response

"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."

"They gave us an estimate which I was happy with and arrived on the scheduled day to complete the work.  One of the cracks was much larger than we thought so they needed to com back with a different product.  They came back but with an insufficient amount to complete the job.  It took a long time to complete but it was sufficient to keep water out of the basement.  Just realize that tax is not included in the estimate."

"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."

"Gregg did a fantastic job repairing our basement foundation, and at a very competitive price. He and his excellent crew showed up on time every day, worked quickly and efficiently, and did a great clean up job. He was with them from start to finish, unlike most contractors who just show up in the morning to drop off their workers. Gregg is an old-school craftsman who obviously takes great pride in his work, and heâ s also someone who thinks outside the box. His company motto is â Exceeding Expectations,â and thatâ s exactly the experience we had. Weâ re totally satisfied with the job he did, and would not hesitate to use him again. Happy to give him our very highest recommendation!"

"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 questions, answered by experts

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation. 

Most of the time, normal foundation settling will present as thin cracks in the foundation and minor creaks in the floorboards. In contrast, you can identify foundation issues by wide or uneven foundation cracks, horizontal or step-shaped gaps on the foundation wall, or cracks that go around corners of your foundation. Foundation problems can also cause changes in your living area, like increased humidity, uneven or sloping floors, nail pops in drywall, countertops pulling away from the wall, and windows and doors getting stuck. When in doubt, call in a professional to identify the underlying cause.

Yes, you can fill cracks in concrete if you’re a somewhat handy homeowner. It’s important to know which concrete patching method to use, as small cracks require different approaches than large ones. It might seem challenging to determine which product to use and the tools necessary for the project, but with a bit of background, homeowners can restore their cracked concrete easily.

It depends on the severity of the damage, lasting from a few days to several weeks.

Foundation repair costs $250 for a minor crack that doesn’t affect the structure’s integrity, although it can cost as much as $800 if it’s a major crack. Call a pro to get it fixed as soon as possible if your crack is bigger than 1/8 inch wide. Additionally, if you need to seal the foundation to fix leaks, it can cost approximately $2,000 to $7,000.
