"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."

"BQ Basement has a unique foam based leveling product (not mud or concrete) that is guaranteed. They did a great job leveling a very crooked (sinkhole) slab and re-graded a series of slabs by my foundation to get the rain to flow away from the basement. Nicely sealed the seam at the foundation too. Thanks!"

"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!"

"I called The Driveway Lady to get a quote and ideas on how to solve a difficult problem with my concrete porch. My home was built in the late 1800s and has a large raised concrete wrap around porch surrounded by beautiful stone walls. Replacement would be prohibitive, but there were some substantial cracks and pitting. It was like walking on an ocean reef, it was so rough, and the repairs made to the cracks wouldn’t hold, but Jean determined that it was otherwise secure with no water penetration below. She suggested they repair the cracks with hydraulic cement and then coat the entire surface with Miracote to seal both the cracks and smooth the surface and protect from future pitting. They worked with me to get the color right when I didn’t like the initial application.  Jean stands by her work and does an outstanding job. The people she has working for her are also courteous, pleasant and easy to work with. I can’t recommend her and her team enough."

"Both times this guy was out, all he told me was what he can't do. Just be aware that they do not do any patching or fixing of walls before painting - they just paint "as is" and nothing more. He also discouraged all of my ideas for remodelling my office/craft room and laundry room the first time he came out - specifically he told me I couldn't put beadboard on the ceiling when I know several people who have done it themselves and it looks great."

"In January of this year, my wife and I decided we needed to transform our finished basement to an inhabitable living area. That would require adding a bathroom and an egress window for â emergency escapeâ . We hired a contractor for the bathroom and began the research on egress windows. As we were anxious to move ahead ASAP, I began contacting companies that installed egress windows. We had a couple of reps come out, look at our basement, discuss the process and quote prices. Estimates ranged from $8000 to $12000. Most had 2 things in common. 1} They could not schedule the job until somewhere in May or June as â windowsâ wouldnâ t be available until then. 2) Any â finishingâ work (necessary sheet rock and trim) would be extra as they did not do that. In March, I happened upon a copy of a regional advertising magazine (Clipper) which came in our mail. In it was an advertisement for â Basement Gurusâ . Since we still hadnâ t made a commitment for the work, I gave them a call. After discussing the job with them, I came to conclusion to go with â Basement Gurusâ . There were five reasons why I made this decision. 1) It appeared to me, based on reviews, the company had a good reputation. 2) The fact that they had windows in stock. This would move job completion date up significantly over what I had been told by at least three other companies. 3) The price. 4) Excavation would be done manually eliminating the possibility of damage to my neighborâ s lawn. 5) Sheetrock and finishing included. Our egress window project (install/follow up sheetrock/trim) was completed on time. Three workers came to our home for the install. They completed the window in three days. Very efficient, professional. Our township inspector came out a few days later and said â all looked goodâ . Also, John the sheetrock/trim person told me he had done a number of egress finishes. He said this one, as opposed to some heâ d seen, looked really good. The sheetrock and trim was completed in one day. An egress window is a big job. They make alterations to your homeâ s foundation! All in all, Basement Gurus did an awesome job! We now have a really nice â livableâ basement adding significant value to our home. Basement Gurus gets my full recommendation!

"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 New Castle, 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.
