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 most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Mold and mildew are always a primary risk with any water damage, but it’s not guaranteed that mold will grow. The chances of mold growth are dependent on many factors, such as the severity of the damage and how quickly the area was cleaned up and dried out—that’s why responding to water damage immediately is imperative. If you suspect you have mold and mildew growth, you should talk to a local mold removal expert .

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

Whether interior versus exterior basement waterproofing is better for your home depends on your budget. The majority of water issues that homeowners experience in their basements are due to conditions that start outside of the home. So, to prevent those problems from seeping in, it’s better to stop them at the source using outside waterproofing methods.
