"Great! Scott did a quality job and was very easy to work with. The best part was that he was very clear in his pricing, itemizing every invoice and reviewing it with us before every payment that was due."

"John Perry underbid all others... with no plan to do the work at all. He preys on Senior Citizens! He requires half down. Sets up a date to supposedly do the work....then never shows up. Doesn’t answer his phone....then goes off when confronted. This is the absolute worst business person...born and raised in our area...to do business with. Always Painting and Restoration was the name of his business 3 businesses ago!!! He just closes them and gets a new person to back him then rips off more citizens. Beware of Always Painting and Contracting....his most current business name. The WALabor and Industries site shows a woman in Centralia as owner.... but This piece of work is just trying to figure out ways to rip people off but cover his butt as a limited liability partner. BEWARE!!! Do not shop the harbor first with this rip off!!!"

Foundation Repair questions, answered by experts

Always hire a foundation repair contractor the moment you suspect your house doesn't have a good foundation. The longer you wait to address foundation issues, the more likely they can lead to bowing floors, cracks in walls and ceilings, sticking doors and windows, chimney and roof problems, and more. Foundation problems can also let moisture into your home, leading to water damage, mold, and mildew problems.

Depending on the severity, a slab leak can go undetected for months or even years, especially if you don’t carry out routine foundation inspections to find foundation leaks early. However, minor leaks are likely to turn into more severe leaks over time, so you might notice increases in water bills and issues with yard drainage, even if the problem is minor.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.

You could DIY the work, but unless you have plumber’s knowledge for identifying and fixing a slab leak and specialized equipment in your tool shed, attempting to DIY your slab leak repair isn’t a good idea. It’s simply not something that the average homeowner can take on themselves, regardless of how many successful DIY projects they’ve got under their belt. You could, however, do something simple like foundation waterproofing yourself to save some money on the post-repair work.

Although it is possible for a house to collapse from a sinking foundation, it will likely take many years, and signs of major issues will be apparent for a while. Homes on hillsides or in areas that experience frequent washouts are at a higher risk of collapse. Still, barring a natural disaster or extreme circumstances, houses are unlikely to fully collapse from foundation damage.
