"Last fall I bought a house with a gas fireplace, and during the inspection it was noted the damper was blocked. The inspector thought that there was probably debris in the chimney causing the blockage. So I hired Absolute Clean to unblock and clean the chimney. They found that the blockage was caused not by debris but by a piece of mortar protruding from the masonry. In fact the chimney had probably never been used even though the house was 47 years old. So it turned out that there wasn't really a whole lot of chimney sweeping to do as far as build-up, but there was a little debris which they cleaned out, and they checked it to make sure that it was safe to use. They showed me how to turn it on safely and gave me some tips on positioning the logs, and where to buy gas logs if I wanted a different look. Very nice fellows.

House Leveling FAQs, answered by experts

Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.

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.

The method involves lifting settled concrete using pressurized cement slurry via drilled holes. This solves uneven surfaces and prevents further settling.

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

Common issues with concrete that may require professional repair or resurfacing include cracks, spalling, uneven surfaces, and weather damage.
