"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!"

"The crew arrived on the planned date and worked diligently.  They were knowledgeable about the issues of an old house and knew exactly what they were doing.  They had to carry out the debris (concrete and dirt), and bring in the material and equipment by hand.  They were careful to partition off the part of the basement where they worked and keep dust and dirt from going out of the work area. The crew did a great job in making sure the work sites were cleaned up and everything was done right.  A truck had to come back 2 days later to finish up the river rock in the outside trench, as they had run out of material.  The yard, considering how difficult it was to dig the trench away from the house, was in very good shape.  There were tree roots ans shale that made things difficult and required  a jackhammer at times.
 It was a difficult and messy job that they did wonderfully, inside and outside. I have been very pleased with the work and there has been no problems with water or excessive dampness in the basement."

"Alex was amazing!! We had a crack in our foundation that another company attempted to repair numerous times. We were fortunate enough to hear about ProSeal and I am happy to report not only did Alex repair the crack to near perfection but the work was done timely, neatly and his customer service skills are top notch. I would HIGHLY recommend ProSeal for all of your foundation needs."

"We were dealing with a stressful basement leak every time it rained heavily, so we called Prime to waterproof our foundation wall. From the initial inspection to the final cleanup, they were professional, transparent, and incredibly thorough. The crew arrived on time, explained exactly how they were going to seal the foundation, and worked tirelessly to get the job done right. We just had our first major storm since the repair, and the basement is bone dry! If you want peace of mind and quality craftsmanship, I highly recommend Prime. They are worth every penny"

"We had some issues with an old addition to house shifting. We found that the walls holding it had some damage and seemed to be crumbling.
 I had two firms come out to talk with me before Foundations Experts. One would not even look under the addition, said he had to come back. The other could not fit into the crawlspace and never came back. 
  Nicks guys were great. Went in took pictures asked questions and already knew the grounds from satellite photos. 
 They sent me a detailed report on what the issues were with all the photos. 
  During this time period they had been a lot of rain. My septic tank collapsed due to erosion and a broken pipe. Nick came out to take a look to make sure the house was safe since this is all connected to the addition. The septic tank was repaired. Nick gave me reports and advice on this in trying get insurance coverage even though the septic tank was repaired by another company.
 At this point the foundation work has been put on hold, because of the expense of the repairs to the septic tank. 
 Foundations Experts went way beyond what they had to do even though that got no work out of it at this time. 
 Nick said he will redo the proposals and take a look again when we are ready. 
Thanks

FAQs for concrete foundation repair projects in Harriman, NY

Visible cracks, water leaks, uneven floors, or walls that won’t line up are classic red flags. You might also notice sticking windows, doors that no longer latch, or exterior cracks crawling up brick or siding. Even a damp, musty basement can hint at trouble. If you spot any of these, call a foundation pro right away. Early inspections cost far less than waiting until the damage threatens your home’s stability.

Yes, foundation problems impact your home’s value. Buyers want proof that the foundation is stable, and a recent, professional repair can actually boost confidence in your home. You’ll need to disclose the work, but documentation showing the structure was properly stabilized, especially with piers in regions known for shifting soil, often reads as a plus, not a problem. Skipping repairs, on the other hand, can cut your sale price and shrink the pool of interested buyers. Taking care of the issue protects both value and peace of mind.

Foundations are engineered for exceptional longevity when constructed correctly and maintained diligently. Concrete slab foundations remain structurally sound for 200 years, while other foundation types deliver integrity between 75 and 100 years. Regular professional inspections and timely maintenance further secure a foundation’s lifespan and ensure your home stays safe over the long term.
