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

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses.
