"We contacted Pierce L. Shallis Landscaping after doing some research and reading online reviews. We needed landscape remediation as water was building up in the front side of our house (during heavy rain) and wanted a new flower bed as well. I contacted them and they got back to me right away. Pierce came out to take a look and after talking to him, I was confident he had the expertise to do the work. To no surprise, he and his crew did a fantastic job. I defaulted to his opinion about what plants would look great in the flower bed. My only request was a small Japanese maple. The communication was great from start to finish. I would highly recommend this company to anyone as they are both knowledgeable and professional. When hiring Pierce L. Shallis, you will have peace of mind that they will get the job done right."

"Working with Just Dry Basements was best described as no-nonsense, fast, and high-quality. In a highly-charged emotional situation like a basement flooding - it is easy to just pick someone to do the work out of desperation. I was lucky enough to work with JDB, who not only rapidly assessed, made a plan together on how we would approach the job, and accommodated a difficult situation where the basement was mostly finished, and they had to carefully deconstruct some of the walls to put in the proper mitigation. A year plus later and a LOT of rain past, the work truly stands the test of time and whatever the elements can throw at it. I have since worked with JDB on other projects, and not just because of the quality of work, but also their fair pricing, friendly and predictable communication, as well as standing behind their work 100%."

Concrete foundation repairs FAQs

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.
