"I was having some issues with water coming into the basement through the foundation and walls during rainy weather. Not flooding, or even shop vac-able volumes, just enough to be annoying and require mopping. Dominic and his crew were here today to install an under-floor drainage system and a new sump pump. I was dreading the demo (I have a concrete floor) and the mess involved, but these guys came prepared for everything! They used dust abatement measures to protect all my basement-stored items, and they removed and hauled all the debris away when finished with the excavation. What really impressed me was the concrete restoration upon completion. I've previously had a sewer line replaced through the basement floor, and the contractor really "botched" the floor repair. I can't describe how different this experience was! The concrete installed today is immaculate! Dominic takes pride in his work and with good reason! The new concrete is perfect! I am thrilled!"

"After explaining all facets of the work he was about to accomplish, the Installer (Mr. Bernard W.) quietly went about his work. The results were truly outstanding - the new system worked perfectly, with piping thru concrete quite cosmetic in appearance. I could not be more pleased. Thank you for quality, top notch service."

"The service I received from Martin's Home Improvement was outstanding! I contacted Martin several weeks ago, he got right back to me and was very flexible with my estimate date/time even thought I had to change it due to shift-work. The estimate was sent to me that night, and Martin was easily able to be contacted with my questions and changes. I was able to schedule the job within the week, it took about 2.5 days from start until finish. Martin and Rob were there promptly at 730am start day. Rob is an employee of Martin's and his work was phenomenal. Rob worked the first two days from 730am to 5pm or so. The quality of the work was worth every penny. Rob was very professional and courteous. Everything was cleaned and vacuumed everyday, and unless you looked into the bedroom you wouldn't know I had a contractor working in my home. Overall I am glad I hired Martin and his company and will again for future projects. They took my old bedroom and turned it into something amazing, I didn't think it could look so nice for the house being 98 years old. If you want your money's worth hire these guys.

"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 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!"

"Excellent. A crew of 3 worked from 7AM to 6:30PM. Removed the old concrete, did all work as explained in the estimate and cleaned up the work area before leaving, all in the same day. We were very happy with the workmanship and would definitely recommend them to our friends."

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.
