About Crawlspace Pros
Local, family-owned and focused on what's below
Most homeowners never go into their crawl space — and they shouldn't have to. When something seems off, like a musty smell, a cold or bouncy floor, or water after a heavy rain, you need someone who will go look, explain what's going on, and price the fix fairly.
That's what we do. Crawlspace Pros is owner-operated, with more than 10 years of experience working under homes in Longview, Kelso and the surrounding Southwest Washington communities. We handle moisture control, drainage, insulation, cleanouts and the structural pieces that hold your floors up.
- Inspection-first: we recommend work based on what's actually there
- Clear explanations, with photos when they help
- Fair, straightforward pricing and free estimates
- Licensed, bonded and insured — WA contractor license OUTSIOG746BH

Common crawl space problems we fix
Most crawl space problems show up inside the house first. Here's what to watch for — and how we fix it.
Musty or earthy smell
Often linked to damp soil, a failed ground cover or wet insulation below the floor. Vapor barriers · Encapsulation
Water after heavy rain
Standing water or mud that returns every wet season usually needs drainage, not just plastic. Drain systems · Sump pumps
Cold floors & high heating bills
Insulation that has fallen, gotten wet or gone missing leaves floors uncomfortable. Insulation
Sloping, dipping or bouncy floors
Damaged posts, a sagging beam or settled piers under the floor. We find the cause and fix it. Post & beam · Floor leveling
Cracks or damaged concrete
Cracked stem walls, crumbling piers or water at the foundation, repaired the right way. Foundation repairs
A crawl space you can't get into
Debris, old materials or very low clearance can block inspections and repairs. Cleanouts · Dig outs

Reviews from our Google Business Profile.
Loved every aspect of working with Johnathon. Straightforward pricing, no hidden surprises, friendly, and hard working. Made every aspect of our crawlspace nightmare easy to understand and went above and beyond to make it happen.
I feel very happy and pleased with the work Jon did under my house. He cleaned up the entire crawl space!! Jon is hard working and I would recommend him highly.
I've been working w/ Jon and CrawlspacePros on some structural issues in my old home, and they've been kind, quality, honest, and they care that I'm happy with the outcome. That means a lot to me. Thank you gentlemen.
Jon and his crew did a great job on some foundation work and vent wells. He was very personable and easy to work with.
Jon did an excellent job working in the crawl space under my home. And also did an outstanding job putting screens to thwart the kitties from setting up there again. Thank you, Jon!
Fast, affordable, and friendly. Add to that they did a fantastic job. Would definitely be referring them to friends and family. Good job guys!!

Questions
Frequently asked questions
What does encapsulation do?
Encapsulation seals your crawl space with a heavy-duty liner over the ground and up the walls, sealed around piers and penetrations, to keep out ground moisture and outside air. If water is pooling, we handle drainage first, then seal the space for a cleaner, drier crawl space. Read the full comparison.
