"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!"

"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 used quality 1st on two occasions in the past year to address water in the basement of our brownstone. They first addressed the problem from the crawlspace - installed a sump pump, water guard trench, and cleanspace wall system (they also added support to the ceiling, which is the floor of a kitchen above). Their approach was sound, the cost was fair, and we were very happy with their service and the work itself. They then returned to address water coming in from the main basement area - we worked together on a reasonable approach that included adding a 2nd sump pump, a water guard trench and cleanspace wall system only where needed. This required a lot of coordination and communication with our plumber as well - all went smoothly, work was performed and cleaned up professionally. So far, so good! I am in construction myself and I reviewed their approach with other professionals including an engineer, and I have a lot of confidence in their products, their pricing, and their work."

"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! "

"We called the professionals at Basement Systems USA after we saw our wall starting to crack from moisture. After much research for a company we found their information and plenty of wonderful reviews (all true). We called to set up an appointment and the gentleman Scott Beard we spoke to was extremely polite and very accommodating. He came out the next day. He was extremely through and was at the house two hours performing an extremely detailed review of the damage. Hi write up was very precise and specific and the estimate we received was fair and right on the money. He was just a very friendly and sociable person and we knew right away that we wanted to hire them for the job. We called him next day and he promptly sent the contract over. The contract was very straightforward and fair and the required deposit was very reasonable. I liked that they didn't expect full payment until the job was done, inspected and approved by all parties. As soon as the contract was signed and the down payment was confirmed they got our appointment set up with the foreman for him and his team to come out immediately. Sean Ryan and his crew were extremely professional, friendly and punctual. They showed up on time, laid plastic down to prevent tracking dirt in (we have carpeting), covered the furniture in the effected area and kept their equipment in one place to avoid clutter. The job was supposed to be done in one day but once they got behind the wall they found additional damage and black mold. Even though this was not part of the original problem (understandable since you can't predict what you will find behind the wall), they offered to eliminate the mold and make the additional necessary repairs. The price for the additional work was also very reasonable. Even better was that they said they would get everything done without having to make another appointment for the new project at a later date if they didn't mind them coming back the next day (Saturday). They worked until dark and got the majority of the work completed. As promised they came back on time the next day and finished the additional work promptly. They did a good job cleaning up and made sure we were happy with the work. The wall looks great (I want to do the whole basement like that now) and the sub pump is working great. We have had no more moisture or water damage. Needless to say we are happy with the final product and appreciate their professionalism and concern with our needs. They went above and beyond (especially by coming out on a weekend to fix an unexpected problem) to get the work done in a timely fashion and with great results. They also have electronic equipment (i.e. iPad) to print out paperwork and take payments which makes it easy if you don't like writing checks. Overall we are very satisfied with Sean Ryan and his crews work, Scott Beard's help in getting everything set up and the whole company for helping us solve our problem. We have already recommended t"

"Had evidence of water seeping thru repaired settlement cracks but one call to company had crew out to do additional work. Time will tell if the additional repairs stop my foundation leaks. Workers were courteous and cleaned up after the job was completed."

"I had a small but complicated, hard to access, and structurally essential repair job on a 60-year-old concrete deck attached to my 280-year-old Pennsylvania limestone farmhouse. I contacted several masons listed for my area on Home Advisor, and included Mr. Grady as a long shot -- I read about his expertise with historical structures and wished I had access to such an expert craftsman, but I didn't think he'd be interested in my teeny job and assumed I wouldn't be able to afford him anyway. He was the first one to return my call and to look at the job, and I thought his price was fair. I believe now it was way more than fair, considering the time he spent. He did extensive research, going over a structural engineer's report I had done previously on the deck and even examining the original architectural drawings and materials invoices from 1959. He showed up at least three times to complete the repair in stages, and has been back a half a dozen times since then to check the job -- and my location is not exactly in his neighborhood. He accepted only enough payment in advance to pay for lodging for himself and his assistant when they stayed nearby one night in order to be there early the next morning. He gave and continues to give free advice about preserving my stone house and patio. If you prod him a little, he might even share some of his personal philosophy, earned over a lifetime of work that is clearly more of an art form than a job to him. Overall, I'd say you can hire one of many competent contractors and get an adequate job, or you can hire Mr. Grady and get superior work by someone who cares about your property as much as you do."

FAQs for concrete foundation repair projects in Kennett Square, PA

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.
