"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."

"Service was great from sales, to installation, to post installation support. Very responsive, very professional. It's hard to find in this 'space'--there are a lot of shady people in basement water damage/repair, and this place exceeded expectations. We've had our repair in place for 4+ years, with only 1 small issue on a wall seam crack, and that was fixed within 24 hours of reporting the issue. Stand up place! Thank you for such great service and support."

FAQs for concrete foundation repair projects in Wilmington, DE

Industry experts typically recommend having your foundation professionally evaluated every one to three years, complemented by personal visual checks twice yearly. If you notice potential warning signs like widening cracks, door alignment issues, or unusual moisture patterns, schedule a professional assessment right away, regardless of your regular inspection timeline. Maintaining this schedule helps identify developing problems before they require extensive repairs.

Be vigilant for wall or floor cracks (particularly those wider than 1/8 inch), doors that suddenly stick or won't close properly, noticeable floor slopes, and gaps appearing between walls and ceilings. External indicators include water pooling near your foundation after rainfall and visible shifts in foundation walls. These symptoms often signal foundation movement that should be professionally evaluated to prevent escalating damage.

Standard insurance policies typically classify routine foundation inspections as preventative maintenance rather than covered services. However, if your foundation sustains damage from a covered incident like a plumbing failure, your policy might include assessment costs within the claim. Review your specific coverage details and maintain thorough documentation of any foundation issues to support potential claims for qualifying events.

Search for professionals with relevant structural engineering credentials or specialized foundation inspection experience. Verify their licensing status, insurance coverage, and client references before scheduling service. Ask detailed questions about their experience with your specific foundation type and what their inspection process entails. Obtaining multiple estimates allows you to compare both qualifications and pricing to select the most appropriate professional for your specific foundation concerns.
