"We have used MTU Services LLC twice in the last 3 years. Two projects involving extreme foundation repair for our home in Spokane, WA. Mark and his crew are OUTSTANDING in every way! MTU has old fashion values, no price gouging, detailed bids and the crew is excellent in communication with the home owner while on site each day. Our major repairs took months because the original builder in the 1950's did not put in appropriate footers and a portion of our house began to sink. MTU also completely gutted a basement room that was compromised, jack hammered the concrete out, installed new metal ceiling beams, posts, dug new footers, metal mesh on the floor, poured and leveled the brand new floor. The hardest working real men I have seen in decades and no complaining what soever.

"We hired SFW to repair our new home that had undisclosed water damage at the time of purchase. TJ was the supervisor assigned to our project and his work was exceptional. TJ is professional, knowledgeable, considerate, kind, thoughtful, courteous, detail oriented, punctual, and always adheres to safety standards. His interpersonal skills are excellent as well. Throughout the entire project, he kept me informed and was transparent about everything related our home restoration. Furthermore, he went above and beyond on multiple occasions to help my family navigate a water damage and new home experience. When we needed documentation of the damage, he helped us by taking 100s of photos. When other new home related projects popped up, TJ was gracious about facilitating the additional projects for us through SFW. We had a gate installed, new hardware installed throughout the house, our cement deck replaced with Timber Tech, and several other small projects that we kept adding to the list! We are extremely grateful to everyone at SFW who worked with us during this 8-month (unexpected) project. Shout out to Jerry, Jay, Jordan, Dominic, Richard, and Jonas! They were also incredibly professional, caring, and helpful during this journey. Jordan was transparent and patient with all things related to billing, Jerry was excellent at managing subcontractors and responsive to our needs as a family. Jerry also provided us a detailed report of SFW findings for our records. Dominic was respectful, professional, kind, detail oriented, and always went above and beyond. TJ and Dominic and other crew members were also incredibly kind to our two dogs and respectful of our privacy in the house. If you are going to have a crew in and around your home, it's sure nice to know they are genuinely professional and considerate human beings. Thank you, TJ, and everyone at SFW!

Basement waterproofing services FAQs
Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:
Water in your basement, including damp walls or puddles on the floor
Mold spots in your basement
Musty smells or odors
Warped doors or walls
Cracks in walls
Insect issues, such as cockroaches and termites
You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home.
However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
