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

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

The purpose of crawl space encapsulation is to prevent mold and moisture from entering your space. If your vapor barrier is properly installed and intact, it will dramatically reduce the chance that your crawl space develops mold. That said, moisture can condense in the area. If you notice excess humidity, you may need to install a dehumidifier to stave off mold and mildew growth.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Rigid foam insulation boards are one of the best insulation materials for crawl spaces. This material insulates the home well, resists water damage, and won't settle like fiberglass or cellulose. Closed-cell spray foam insulation is another effective insulation that both seals the air and provides excellent thermal protection for hard-to-reach spaces like crawl spaces.
