Why Longview crawl spaces deserve a look

Longview was built on purpose. The Long-Bell Lumber Company planned the city in the early 1920s on the low ground where the Cowlitz River meets the Columbia, and it was incorporated in 1924. Many of its historic buildings date from 1923 to 1934, and suburban neighborhoods followed in the western part of the valley in the 1960s. That means a lot of Longview homes have crawl spaces that are 60 to 100 years old — with plastic, insulation and supports that have been patched, disturbed or never updated.

The weather adds to it. Longview averages about 48 inches of precipitation a year, and the rain arrives in a long wet season: November, December and January each average more than six and a half inches, and "Pineapple Express" storms can drop several inches in a few days. Crawl spaces that are fine in August can be damp, muddy or wet by January.

What we see most under Longview homes

That's why we inspect before recommending anything — so you get a clear plan for your home.

Before you call

It helps to note what you're noticing and when: does the smell get worse in winter? Does a floor feel colder in one room? Has anyone been under the house recently for plumbing or electrical work? If you're buying or selling a Longview home, have the inspection report handy — we can talk through what it says about the crawl space.

Local, family-owned and close by

We're based in the Longview–Kelso area, so Longview isn't a long drive for us — it's home. You'll deal directly with the people doing the work, get a straight explanation of what we find and a free, straightforward estimate.

Questions

Longview crawl space questions

My Longview home is from the 1920s. What should I expect underneath?

Older homes vary a lot. Common things we check are the ground cover, insulation, posts and piers, and signs of past water. Some are in great shape; some have decades of patches. An inspection tells you which.

My crawl space is only wet in winter. Is that a problem?

Yes. Water that sits under a home for months each year damages insulation and wood. We'll find where it's coming from and put the right drainage in place to keep it out.

How quickly can you come out?

We're local and available 24/7 by phone. Call to talk about timing for your inspection.

How do I get an estimate?

Getting started is easy. Call or text (360) 470-4956, or fill out the form on this page. We'll learn what's going on beneath your home, schedule a time to take a look, and give you a straightforward estimate.

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.

Henry RettingerGoogle review

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.
