Our mission at MB FLOORING LLC is simple: to provide high quality services for our valued clients. With years of experience our team goes above and beyond to cater to each projects specific needs through open communication and exceptional service. For more information or general inquiries, get in touch today.

"Everything about there work was excellent! First they were prompt in coming out to give us an estimate and kept to their schedule. Their estimate was detailed and reasonably priced (we did have other estimates and their detail was the best and their prices were in line with, actually a bit lower, that the other estimates). Their estimate was based on installing a "floating" floor which would be the least expensive way to proceed but when they started the job it became apparent that a "floating" floor would work but wouldn't be the best and they explained to me how a "nailed" floor would be a much higher quality job. I agreed and the indicated that a "nailed" would incur more costs. When I received the revised cost proposal I noted that it was reasonable in regards to the additional materials and they were willing to absorb the additional labor costs. I found this to be more than fair on their part, and very positively impressive on their part - VERY HONEST PEOPLE TO DEAL WITH. Their people came in, worked hard for long days, kept to their committed schedule, and when little issues came up they always dealt with them in a way that gave me a better quality job. Our end job looks GREAT. I don't want to redo my floors again soon, but if it happened MB Flooring would be the ones getting the job. I would be glad to let people come to my house to see for themselves the kind of work they do. If you have a choice give MB Flooring the most serious consideration. Ed O'Rourke Florence OR p.s. Note on costs we purchased the engineered hardwood and ceramic tile separately."

Basement Waterproofing questions, answered by experts

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

It can be safe to live in a house with minor foundation problems as long as the issues are checked and monitored by a professional. Minor cracks are rarely a cause for structural concerns, but signs of leaks, sinking, or bulging walls should be strongly scrutinized by a foundation specialist. Similarly, it's always smart to hire a professional when you're concerned about buying a house with foundation repairs.

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.
