"Work was performed on schedule as quoted. Kept me up to date as project progressed. Did a fantastic job which really enhanced our homes efficiency. Lower lever of home is dry and temperature stays consistent on both levels now. Premier Basement System has completely eliminated the damp musty odor in our home and eliminated any concerns of water or moisture in the crawl space. Additionally the system seals off the crawl space from bugs. When the L&I inspector inspected the electrical work he commented on the quality work and the fact this was the cleanest crawl space he ever saw. Highly recommended!"

"We’ve had a lot of crews in our home for various projects over the years, and I have to say this was one of the most courteous. They worked hard, navigating through our kitchen to access the basement and I really appreciated their efforts. Thank you MTU, we now have safe walls in our cellar and fresh beams to keep the house standing ;)"

Customers say: Quality work

"Matt did such a great job of tearing down and removing my dilapidated garage - he handled everything from getting the permit, arranging for asbestos testing, getting the electrical located and delivery of the dumpsters. He was careful to not damage any existing fences, and when he left, the area had been raked clean and there wasn’t a trace of the old building left behind. I would absolutely hire him again. Very professional, easy to work with, and kind."

Basement Waterproofing questions, answered by experts

During a basement waterproofing project in Spokane, specialists closely examine foundation walls—particularly those exposed to heavy snow accumulation or runoff. They assess wall joints, footings, and areas near window wells, as well as exterior grading and French drains. Inside, attention is given to floor cracks, utility penetrations, and sump pump locations to address all potential water entry points unique to Spokane’s seasonal moisture challenges.

Helpful?

Completing basement waterproofing in Spokane significantly enhances your home’s comfort and livability, especially during the city’s wet springs and snowy winters. By sealing out moisture, you prevent mold growth, musty odors, and allergens, creating a healthier environment. Waterproofing also helps stabilize indoor temperatures and humidity, making the basement usable year-round. A dry, well-protected basement can increase property value and provide peace of mind during heavy rainfall or snowmelt.

Helpful?

Spokane homeowners should create a seasonal inspection routine by checking for damp spots and condensation after spring thaw, ensuring sump pumps and French drains are clear and operational. In summer, monitor for high humidity and inspect for new wall or floor cracks. Before autumn, confirm exterior grading directs water away from the foundation. In winter, look for ice buildup near basement windows and test dehumidifiers monthly to prevent hidden moisture issues.

Helpful?

In Spokane, professionals determine the boundaries of a basement waterproofing project by assessing the home’s foundation, soil composition, and proximity to high groundwater areas common in the region. They carefully inspect exterior and interior basement walls, especially those facing prevailing winds and runoff. Evaluating existing sump pumps and drainage systems, they ensure the project scope aligns with local building codes and site-specific moisture risks before starting work.

Helpful?

In Spokane, quality basement waterproofing is evident when basements remain dry during heavy rain and snowmelt, and humidity stays consistently below 60%. No new cracks, musty smells, or visible mold should appear. Effective waterproofing integrates with sump pumps and drainage systems tailored for Spokane’s freeze-thaw cycles. Comprehensive documentation, a detailed warranty, and visible improvements in air quality and comfort are also strong indicators of a job well done.
