"I have hired Permaseal to fix my unleveled patio concrete floor that was and still causing rain water to get to my basement, I have paid them $2,014.33 as down payment, they showed up one month later for the job, which is injecting foam under the concrete slab to lift it back to its original correct level. I came back home that day to find out that they have left and that the concrete slab was not only still unleveled, but they cracked it and patched it on multiple locations. I have called their customer care number more than a dozen times in attempt to understand what is going on, and on each occasion, I was told that the project manager was going to contact me back, which never happened until i made the next call, They have finally explained to me over the phone that it was the best they could do and that they could not fix my patio floor. I asked for a refund and did not hear back. I have documented pictures of before and after showing that the job was not done and cancelled the check with the remaining balance. I have not heard anything back from them since then, until i started getting debt collectors' emails on December the 5th from a business called FCR Services."

"Went with Kerry roofing to replace the leaking roof and leaking chimney on my mom's house. The chimney repair went great. They redid the entire top, installed a new liner, and tuck-pointed a good portion of the wall on the house around the chimney which was in also in need of repair. No more leaking chimney! The roof didn't go quite as well as the chimney work. The actual work was done on schedule but there were issues with it after they were done. But Tony was more than happy to get things fixed. Twice I called about somethings I saw that didn't look right and he was able to answer my questions (I'm not a roofing expert, was just comparing to other roofs) and then had a guy out to fix things when he determined that yes it wasn't done right. I realize this was a complicated roof, with many steep gables, but would expect an established roofing company to be able to handle the job, so was a bit disappointed there. But I appreciate that Tony is always a phone call away and able to answer my questions and send someone out if needed. They stand by their work."

Foundation Repair questions, answered by experts

Yes, slab foundations can sink just like any other foundation type. Floating slabs are the most prone to differential settlement and foundation sinking because they sit directly on the surface of the earth. Slab foundations that have footings—including slab-on-grade foundations and monolithic slab foundations—get additional support from soil further down and are less likely to sink over time, especially under larger, heavier structures.

Water damage in your home’s foundation is gradual, often beginning with small cracks that let water seep in. Over time, this weakens the foundation, which then allows in more water, causing significant structural damage. This process can take months or years to destroy your foundation, and the repairs can be very costly. Have your foundation inspected regularly to prevent significant damage.

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.

Homeowners insurance doesn’t usually cover a sinking foundation. While insurance will cover some kinds of foundation damage, coverage is usually limited to damage from natural disasters, fire, or impact. Foundation sinking is rarely covered by insurance, so it’s a good idea to make repairs early on to avoid costly problems in the future.

No, hairline cracks in concrete are generally not a problem as they do not impact the strength and longevity of the concrete. Generally, cracks less than 0.3 millimeter wide don’t impact the structure. Hairline cracks can grow over time and weaken the structure, such as in a home foundation. Some hairline cracks can also cause leaks in a foundation. It’s important to watch the cracks to see if they grow. Contact a concrete contractor if you notice cracks exceeding 0.3 millimeter wide.
