Crawl Space Repair Services You Can Trust

Common Signs Your Crawl Space Needs Repair:

Your crawl space plays a vital role in your home’s structural integrity and indoor air quality. Unfortunately, it’s also one of the most overlooked areas when it comes to maintenance. Issues like sagging floor joists, water intrusion, wood rot, and mold growth can quickly escalate, leading to costly damage and unhealthy living conditions.

Sagging or uneven floors above the crawl space

Gaps between floors and baseboards

Musty or damp odors inside the home

Increased humidity or condensation indoors

Visible mold or mildew in the crawl space

Wood rot or soft floor joists

From Structural Problems to Water Damage, We’ve Got You Covered

Common Crawl Space Issues We Solve

Crawl spaces are often out of sight and out of mind, until problems arise. Unfortunately, the damp climate in Western Washington makes these spaces especially prone to moisture, wood rot, and structural deterioration.

  • Water Intrusion – Rainwater runoff or plumbing leaks can leave standing water in your crawl space. Over time, this moisture weakens support beams and creates conditions for mold growth.
  • Wood Rot & Mold Growth – Excess humidity and poor ventilation allow wood beams to absorb moisture, leading to rot. Mold and mildew thrive in these damp environments, impacting both your crawl space and your indoor air quality.
  • Sagging Floors – If your floors feel soft or uneven, it’s often because the crawl space joists are weakened by moisture or lack proper support. Left alone, this can compromise your home’s structural stability.
  • Foundation Cracks – Shifting soils and constant moisture pressure create cracks in crawl space walls, allowing even more water and humidity to seep inside.
  • Poor Ventilation – Without proper airflow, humidity builds up, accelerating wood decay and encouraging pest infestations.

Frequently Asked Questions About Crawl Space Repair

How do I know if my crawl space needs repairs?

Signs include musty odors, visible mold, pooling water, sagging or uneven floors, cracks in the foundation, and pest infestations. If you notice any of these, scheduling a professional inspection is best.

Will crawl space repairs improve my home’s air quality?

Yes. Around 50% of your home’s air comes from the crawl space, so sealing and repairing it can significantly reduce allergens, mold spores, and humidity.

Do you offer financing for crawl space repair?

Yes, we have flexible financing options to help make repairs more affordable.

Is crawl space repair worth the investment?

Absolutely. Repairs protect your home’s foundation, prevent costly structural damage, improve energy efficiency, and enhance indoor air quality – all of which can increase property value.

Will repairs prevent future problems?

When done correctly with the right solutions – such as encapsulation, drainage improvements, and humidity control – crawl space repairs can prevent moisture damage and structural issues for decades.

Will repairing my crawl space help lower energy bills?

Yes. Moisture and air leaks in crawl spaces make your HVAC work harder. Repairs such as encapsulation and insulation help reduce energy loss and improve efficiency.

Can crawl space repairs stop pest infestations?

Absolutely. Many pests—like termites, rodents, and insects—are drawn to damp, unsealed crawl spaces. Repairs that include sealing and ventilation improvements make your home less inviting.

What happens if I ignore crawl space issues?

Problems like wood rot, mold growth, and structural damage will worsen over time. Ignoring these issues can lead to costly foundation repairs and unhealthy indoor air.

Update 4/12/26 The company reached out to us, came to our home and made a plan to properly lift our house. The work was done in a timely manner and we had a much better experience with them this time around. We are very happy with how things turned out. Awful company. We paid over $38,000 to raise our foundation 1.5”. It started cracking and they were unable to do what they said they could. They “stabilized “ it and left with our savings. It was the biggest waste of money and I suggest you go elsewhere. Garbage. Our house feels like it’s sinking more.

So I had some work done by r and r back in 2019. I had six piers put in and really enjoyed Corey the owner… fast forward to 2026 and the other part of my house started having weird sounds and a crack in my ceiling… I live on a hillside and tons of water comes my way and a user error with a downspout may have caused more issues… I made an appointment to have him come Out and do an inspection with a bid…. It’s pretty rare these days to not feel like you have gotten taken… Cory did all the measurements and well it appears the house is just settling. The house was built in 1980 by the original owners and was definitely not built straight. Anyway… Cory literally put me at ease and said. “Let’s just keep these measurements and check them out in a year or so. “He could have easily have just said… “yup. You need six piers….” He didn’t. I highly recommend r and r foundation… thanks for being honest… it goes a long way! Also… when I do need the work done… I, of course, will be using them!

House built in 1913 did not disappoint with challenges with a leaking foundation into the basement. But, R&R came through and I am able to feel confident that any further water issues are no longer. If the opportunity presented itself, I would hire them again.

I had them come out to my house to look at an issue of water seeping into my garage which is built into a hill. For reasons that have nothing to do with them, I didn't end up getting the work done. However of the four companies I had look at it, R&R's assessment was easily the most thorough. They are the only one that did any significant inspection outside of the building rather than just inside the garage and their prices were comparable to the other companies I checked out.

Had R and R do some work on our older home that needed an update to the crawl space foundation posts a few years back. Work was accomplished in a timely and professional manner. Now in 2025, we are selling our home in a slow market and want to upgrade. We need to show the new buyers the application to transfer the foundation warranty ahead of the inspection in a few days as a show of good will to close the home. R and R's marketing manager, Jordan, was able to accomplish this promptly within one day for us and really set us up well to help close our home. While the foundation repair was important, it was years later, being able to connect with R and R again, and show the new buyers the work they had done and that it was done by a reputable company, that helped seal the deal.
