Diggs Building Technologies Corp.

Tim and Jake replaced an old support beam and structural wall in our basement with new footings, posts, and steel beams through the length of the house. They handled the project from beginning to end with excellent communication and service. Before they could begin work, the engineer had to draw up plans and Diggs had to get permits approved. Tim worked in lockstep with the engineer and me - he stayed in touch so that I always knew where we were in the process. The work itself took them less than a week, and they left my house standing stronger than ever. If you have a structural issue in your home, these are 1000% the guys to call. Thank you, Tim and Jake!

Tim and Jake Hillman of Diggs Build Technologies are the right guys to fix properly your home-foundation problems. They assessed the issues with my leaking and bowing basement wall, and patiently explained why replacing it was the right solution (and merely propping it up wasn't). They carried out the work in early summer 2025, along with an exterior sump pump, and sorted out problems related to rotten beams they encountered along the way. I highly suggest you remain on site on their working days so you can learn about and consult on the work, which is interesting in itself. Naturally such great guys are in high demand, but they're worth the wait and expense.

Great experience for a large project. They were extremely professional and attentive.

Very experienced and professional.

Tim explained the project details in advance and how this should alleviate basement flooding. Tim and crew, excavated to below slab on 2 sides of house per plan; repaired cracks and holes in foundation, applied waterproofing and perimeter drainage with pump. Backfilled and leveled work site and seeded grass. Crew was professional and hard working. First rainfall few days later showed everything working perfectly.

I was pleasantly surprised at how professional and knowledgeable everyone was. They are by far the best contractor I have ever hired. Even though they were working while I was away, they finished on time, left everything the way they found it if not better, and did a great job. Thank you Tim and the rest of the guys for a job well done.

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.

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!

When you meet Tim you know that you are dealing with someone who is very knowledgeable and a hands on boss. His crew went to work as soon as they arrived and did not stop until the job was complete and the site was cleaned up. My wife and I were very pleased with the entire experience . We would not hesitate to recommend Diggs Building Technologies Crop to anyone.

This is a family owned and operated business that will treat you as if you as family. Things were explained in great detail the follow-through was amazing. I highly recommend them.

Guys came in and worked. No lollygagging or long breaks or any of that just plowed through on a dirty two-day job and their work made me feel a heck of a lot better about the structure of our home. Did great work. The only complaint is that they did not repair a small basement window casing that they pried open to get materials to the basement. I am sure had I contacted them they would have come back and fixed it, but it was not anything nice to begin with and I was able to repair myself pretty easily so I never even brought it to their attention.

Tim had initially come over for the installation of a French drain on the side of the house, but instead uncovered that our foundation had receded away from the house due to past water damage. He immediately stepped into gear explaining every detail to me and gave me a quote for the amount of work that needed to be done. He and his crew made time in his busy schedule to get the job done and finished it completely in 3 days. I am so grateful for the work they have done and how quickly they did it. I highly recommend this business for anyone experiencing foundation/water damage issues. Thank you from the bottom of my heart!

When it rained my basement would get 2-3 inches of water. Tim and his team redirected all of the drain pipes (5 in all), reshaped the slope of the land surrounding my house, planted grass seed, and left the yard spotless. Now my basement is drier than Arizona in mid-July. These guys are pros, they finished in a day. It was a pleasure to see these men work! Their price was more than fair. You can't go wrong with DIGGS! Thank you, Tim!

From the first day we met til the last day of the job being completed, Tim, Jesse and Jake were on time, worked from the time they arrived until the time they left, cleaned up everything and did one incredible job and saved our house from total collapse. The customer service, superb, friendly and very professional. They knew exactly what needed to be done and did it. I would hire them again and would recommend them highly to anyone looking for this type of work. We will definitely have a long working relationship. Don't hesitate call them, you will not be disappointed.

Received a call from Tim and explained the moisture in the basement and he was very knowledgeable and helpful. Very honest and took the time to explain the whole process and how to go about it. Very few people like him exist in this world. Highly recommended and well experienced. You wont be disappointed. Thank you Tim.

Really great guy. Honest, hard working and did exactly what he said needed to be done to without cutting corners or adding unnecessary fixes. Work quality was great and he explained what he needed to do and why along the way. Definitely will hire him again for future work needed.

Tim Hillman and his team were great to work with. I have a 105 year old house, which had an addition built over 40+ years ago, over a crawl space. The foundation of the addition had become unstable & the main support beam under the original part of the house had some bowing. Tim contacted me in less than 24 hours & came over to assess the situation. He determined that it was a two part problem. He could do phase 1 now & the other part in the Spring. He gave me a written estimate for phase 1, which I accepted. Within two weeks, the phase 1 project, which included a new steel support beam under the crawl space & stabilization of the main support beam of the original house, was completed. This type of work is not cheap; but, Tim gave me a very fair price. He did everything that he said that he was going to do; and, he did it well. He worked quickly and he stayed in constant communication with me. I really appreciated his service; and, I look forward to working with him in the Spring on Phase 2 of this project.

Was great: will keep their contact info:

They were so helpful and nice. They explained all about the work that needed to be done.

I called Diggs Building Technologies Corp and was able to speak to Tim right away. I was fortunate that Tim could come to my house the next business day to evaluate the eroding block foundation situation that I had. I was provided an expert opinion and quote the same day. Impressed with Tim s knowledge, experience and great reviews on Home Advisor, I hired Diggs to perform the work. Tim also knew that I wanted to get the blocks replaced before the weather turned cold. Tim started the very next day and had the job done within two days. He also had looked around the house and advised that I should add fill around my foundation to adjust the required pitch for water runoff. Thank you Tim for all of your advice and suggestions! I would highly recommend Diggs Building Technologies Corp for any foundation work you have around your home!

On time to the point did not miss a single detail in repairs and explained everything so that you understand the work that he did and the guarantee of his work.

+Tim was the only pro who contacted me and made an appointment to inspection the house foundation and driveway adjacent to the foundation where the leaking was occurring. He looked at the pitch of the yard behind the house and from the driveway to the house. After a thorough inspection outside the house, he and his son Jake went into the basement to see where the water leaking was most prevalent. Following these two inspections he made verbal recommendations to correct the problems . He followed this up with written proposal for the work, along with a cost estimate. After receiving this, I sent him a detailed email with questions about the proposal, which he promptly answered, to my satisfaction and I agreed to have him do the work. On the agreed start date, he was on time with his excavator and crew of 2 to start the project. Weather was a factor and I was amazed how quickly they did the foundation repair, built a temporary wooden step with small deck into the back door of the house and laid the underground conduit for the electric power to the garage. There have been several heavy rain falls since this project was completed and the water leak is gone. The driveway project is scheduled for Spring 2020 when the weather will be more conducive to replacing the driveway. I highly recommend Diggs Building Technologies Corp for all phases of foundation repairs and related draining problems.

Tim was a true professional from beginning to end on this job. We had an 1870s rear foundation wall with a water problem that everyone else kept telling us to spray foam and forget about. Tim was the only one who we felt really had an understanding of how to permanently fix our water issue. Out of all the contractors we have worked with on our Victorian house restoration, we found Tim from Diggs Building Technologies to be the most knowledgeable in his field. He is an old school iron worker with an intense understanding of structure. In addition, he is not scared of hard work and to do things the right way. From the start, he was not scared off from the difficulties our foundation project presented -- poor excavating access over a 9 foot retaining wall, no driveway for brining in or removing fill. Nor did he back down when we discovered an old cistern trapping water near the foundation, an unexpected and unwelcome surprise. With Tim's expertise, the project kept rolling. All of Tim's team members are extremely professional, kind, polite and hardworking. If structural knowledge and attention to finer details (he even cleaned our my gutters after he found them to be running slowly after a rain storm) are what you are after, then hire Tim immediately. We are eternally grateful! Chris & Beth
