"Great. I have an old house built in 1905 with stone foundation walls and another part with cinderblock walls. After learning the difference between their WaterGuard and crack repairs and what other companies do, I chose them because their upgraded products and ideas really made sense and I was willing to pay a few bucks more for better stuff and a good company. They ended up being the middle guy in cost, but way better quality I think."

"IT WENT VERY WELL. BQ SYSTEMS RESPONDED QUICKLY TO MY REQUEST ( HAD A NARROW TIME FRAME: HAD TO GET IT FIXED SO I COULD SELL MY HOUSE.) AND THE FOLKS AT BQ SYS. DID EVERYTHING THEY COULD TO HELP ME. THE REPAIR TO THE FOUNDATION WALL WAS COMPLETED IN LESS THAN ONE DAY AT A FAIR PRICE. I AND THE NEW OWNERS ARE VERY HAPPY WITH THE REPAIR!"

"It went well and I no longer have to worry about a water leakage during a heavy rainstorm or snow melting. The work crew was on time each day and made every effort to keep the dust from entering the upstairs. They were very considerate and seemed to enjoy working together. They took pride in doing the job well and informed me of any changes necessary and asked permission to make modifications with my approval."

"As a homeowner, realizing you need basement waterproofing, mold remediation, potential foundation repairs, an additional sub pump AND a method to block moisture can be incredibly overwhelming, specifically finding a qualified trustworthy waterproofing and remediation company near me, thankfully I was connected with Basement Gurus. Living in the Philadelphia, New Jersey and Delaware area there were countless companies available, though shortly after putting in a request, the installation manager promptly contacted me and continued to make herself very accessible throughout the entire project. Her effective communication and patience guided me through the entire installation process and follow up. When faced with a wet basement, it is essential to choose a company which is knowledgeable, skilled, and thorough, Basement Gurus exemplified all of these qualities. There crew arrived on time each day and tirelessly worked until EVERYTHING was done to their quality standard, this hard work while putting in the time and effort is rarely found these days, I am glad Basement Gurus hires waterproofing specialists and contractors who clearly take great pride in a well-done job. They were respectful to me and my family, were meticulous throughout, and incredibly open to answers any questions I had. The boss took time to meet with me to discuss any and all concerns that I had. This demonstration of professionalism and responsiveness showed that their priority is to provide stellar service to their customers and ensure quality work in order to resolve any issues with moisture, mold, installation of drainage systems and countless other services. Overall, Basement Gurus demonstrated expertise in basement waterproofing; utilizing the best approaches, most up to date systems and equipment , punctuality and overall work quality."

"We finally found the right contractor! We had 3 projects involving the basement, Master bath and front porch. Martin and his team are very skilled. The work is high quality, efficient and done correctly. Estimates are provided in writing in advance of the job. Martin is often onsite - either doing the work himself or supervising and guiding his team. He communicates well and often and he stands behind his work. We had a small issue in the Master Bath with the painting on the ceiling. He came immediately to inspect it, figured out the issue and had his team redo the ceiling paint. It's now perfect. He is also strategic in making suggestions and giving creative ideas on how to approach the job in ways we had not thought of ourselves. I highly recommend Martin's Home Improvements."

"?I own a 200-year-old farmhouse with a stone foundation, and I was really worried about the integrity of the structure. After reading some bad reviews about other companies damaging stone foundations, I chose Basement Waterproofing Specialists. They are a 4th generation family owned company.I was so glad I did?they were professional, thorough, and really took the time to protect my home. My basement is finally dry, and I feel confident . I would highly recommend them in every way! Price? Professionalism? Quality? And a lifetime of the structure warranty that is transferable?? Thank you. Mark HB Homes LLC"

"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

"Patrick and his team were wonderful to work with for our stone and brick repointing! They came on time as scheduled for both the quote (which was very fair for the work that needed done) and actual work start date. The work they did looks amazing, and they took care to make the new sections of mortar have the same style as the old sections on our beautiful Victorian. Patrick even pointed out several other issues (some of which we were aware of), and prioritized them based on severity. We will happily be hiring them again for our masonry needs!"

"How many stars can I give? I am extremely satisfied with the work and this company. From the initial contact to the final clean-up and later sealing it was quality work done with high level of craftsmanship, attention to detail, and professionalism. They worked to my specifications on shaping some curved sections and even suggested that a small landing step I had requested was not necessary. They were correct. Glad i trusted their judgement. A four man crew was on time (early) on each day, and worked through two if the most brutal days of the summer in intense sunlight with heat index near or over 100. At the end they cleaned so it looked as if they had not been there-except for an attractive new addition. The crew itself was great-answered my questions, thought about my suggestions, explained all steps in the process. The concrete used is high quality-4000 psi in compressive strength, 5 in and 4 in thickness (area specific) and rebar and wire mesh reinforced on a 5-8 in bed of compacted stone. Having wet the new pad over several days it is pitched perfectly for water run-off. Working with contractors is not always easy. This was a pleasure. I expect to enjoy the benefits of new area for many years. Their non cracking guarantee is great. A quality company that I highly recommend."

FAQs for concrete foundation repair projects in Wilmington, DE

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.
