How Tacoma Impacts the Status of Your Attic or Crawl Space
How can you tell if you should have the professionals take a look at your attic or crawl space? Many factors can lead to different problems. Attic Projects helps homeowners grapple with these underlying causes through the latest home improvement solutions.
Tacoma’s Climate
Hot summer months in Tacoma can do a number on your attic, as the temperature inside can become sweltering without proper insulation and ventilation. This means you could find yourself facing moisture issues year-round, as Tacoma’s wet winters can be just as harsh.
How Old is Your Home?
Tacoma has older homes compared to many other regions on the West Coast. The median home age is 52 years. With an older home, you have good cause to suspect that your attic and crawl space may not be up to modern standards. Unless you have already had renovations, it may be time to call the professionals.
Mold and Moisture
Tacoma’s wet and comparatively mild winters pose a real mold growth issue. If you have standing water issues in your crawl space, then serious mold problems could develop over time due to the amount of rain the area receives.
Rodents in Tacoma
Unfortunately, the proximity of Tacoma to Seattle means that there is an established rat presence. You may find yourself dealing with a variety of species, including Norway rats, roof rats, and assorted mice. However, effective rodent-proofing can keep them all out of your home.
Requirements for Insulation
When you have new insulation installed, it is evaluated based on the R-value. This number depends on the type of material and the thickness, and it quantifies how well your insulation blocks the passage of heat. Tacoma is found in EPA climate zone 4, so the recommended insulation for attics is between R-38 and R-60, with crawl spaces at R-25 and R-30.

Frequently Asked Questions about Attic Services in Tacoma
What’s the recommended R-value for attic insulation in the Tacoma area?
That’s a question we get asked a lot. For homes here in Tacoma, the county requires a baseline of R-38 for attic insulation. But honestly? We think that’s just the starting point. At Attic Projects, we often recommend upgrading your attic insulation to R-60 for our wet winters and warm summers. It’s a smart move that helps your home hold its temperature better. While the initial cost is a bit higher, an R-60 insulation job pays off faster by cutting down your utility bills.
How do rodents typically enter an attic, and how can I stop them?
You’d be surprised how creative rodents can be. They usually find their way into a Tacoma attic through tiny gaps around pipes, roof vents, or small holes you’d never notice. That’s where our rodent proofing comes in. We do a full attic retrofit, which just means we fix the problem for good. Our crew finds and seals every single entry point, pulls out any ruined insulation, and completely sanitizes the space.
My Olympia attic gets really hot in the summer. What are my options?
A hot attic in the summer is a common problem around here, and it makes your AC work way harder than it needs to. You’ve got a few good options. Proper attic ventilation is key—we put in things like roof vents or attic fans to push that hot air out. You just have to be careful not to mix different types of vents, or it messes up the airflow. But the real secret is air sealing. Before we do anything else, we seal up the gaps in your attic floor.
What’s included in a full attic cleanup and retrofit?
A full attic retrofit is our way of getting your attic healthy and efficient all at once. It goes way beyond just sweeping up. First, our crew pulls out any old, dirty, or ruined insulation. Then we do a deep sanitization of the whole space—this is a big deal if you’ve had rats or mice up there. Next is air sealing, where we close up all the little gaps and cracks. Finally, after we make sure no pests can get back in, we blow in new insulation to the right R-value for the area.
