"Jack and his crew were thorough, professional and courteous throughout the entire waterproofing project for the basement, which included outside drainage work to better direct water away from the house, and the foundation repairs that were needed. He provided a detailed estimate and explained all facets of the project. Jack also provided additional recommendations for repairing the house gutters and downspouts. The home was built in the 1940's and the basement would flood following rain. Since the repairs, three rain storms within five weeks, each with over 3 inches of rain, have occurred and the basement waterproofing project was immediately tested. It has remained dry!"

"Im am so happy with the work that was done on my house. Tyler came and gave a very fair estimate on lifting my concrete side entrance stairs to my basement. He explained every step of the process and did exactly what we wanted with no issues. Everything was done to perfection. No damage was done and you cant even tell the stairs ever needed a repair in the first place. I would highly recommend this company and would hire again for any future jobs."

"I recently had a roof repair done, and I couldn?t be happier with the results. The team at dryshield arrived on time, were professional, and explained every step of the process in detail. They identified the issue quickly and provided multiple options before deciding on the best fix for my situation. The work was completed efficiently without causing any disruption to my daily life. They cleaned up thoroughly after finishing, and the materials used looked high quality. , and I?ve had no leaks or water damage since the repair. What impressed me most was their attention to detail ? They also offered a clear timeline and kept me updated throughout the process. I would highly recommend them to anyone needing roof repair or replacement. I plan to hire them again for future home improvement projects. Rating: ????? Recommendation: 100% ? I?ll definitely use them again"

House Leveling FAQs, answered by experts

Concrete leveling is absolutely worth it if you have sunken concrete slabs and want to restore them to level, especially if the slab is part of your home foundation. Concrete leveling is less than half the price of replacing concrete sidewalks, patios, walkways, and pool decks, and it’s about a quarter of the cost of replacing a foundation. If you also treat the underlying problem, it can be a worthwhile and permanent solution.

Charges correlate with surface size, settlement depth, and access, often yielding significant savings over concrete replacement.

Mudjacking can be an expensive foundation repair process, but in many cases, it’s well worth the investment. This is especially true if you’re lifting a portion of sunken foundation slab back into place. In that case, mudjacking can help avoid major structural damage and even home collapse by restoring the integrity of your structure with minimally invasive procedures. Mudjacking a concrete patio, walkway, or sidewalk can be worthwhile because it removes tripping hazards and makes your outdoor area more aesthetically appealing.

Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.

Costs range from $500 to $1,500, depending on the size and condition of the area.
