"On day 1 they removed (sucked out) 3 levels (and three different types) of insulation. They were very neat and cleaned up afterward. They showed me pictures of the cleared attic. On day 2 they blew in new insulation, sealed an unused vent (which was causing a draft) and installed a new attic hatch (old one was broken, unsealed and not insulated causing a draft). Everything was done as agreed and in the timeline expected. They are also a partner with Energy Trust of Oregon which is a bonus."

"Ulises was able to get in quickly and get the job completed insulating my shop ceiling trusses with batt insulation. I would have preferred white FSK instead of clear plastic but it would have put me way over budget Overall they did a good job"

"Did a great job of installing insulation and drywall however, they cracked a wall when installing the drywall, they hammered rather than screw it into the studs. Now I must repair the cracked wall. Somehow my compact florescent light also disappeared from the laundry room . They also initially wanted to put the R-30 insulation on top of the R-11 that was already in the ceiling. When compressed the insulation would have lost some of its insulating capabilities so I had to tell them not to do that. Seems they should have known this."

"I had an extensive rat issue in the insulation under my house. The Crawlspace Crew came over the same day to give me a quote and inspect my crawlspace. They organized the entire job, including removing the insulation, setting up a new barrier, spray underneath my house with an antimicrobial chemical and reinstalling new insulation. They also orchestrated with a pest control company to come and set traps, and close up any holes that were ports of entry for the rats. They were extremely efficient at communicating back with me and Two to the timeline. Overall, I was very impressed with the Crawlspace Crew."

Insulation questions, answered by experts

In Portland, frequent rain and fluctuating temperatures make moisture control a top priority for insulation service projects. Choosing insulation types like closed-cell spray foam or rigid foam board helps resist dampness and prevent mold. Installers often recommend vapor barriers and attic insulation upgrades to combat condensation. Scheduling work in late spring or early fall can minimize weather-related delays and ensure optimal installation conditions.

Helpful?

In Portland, you’ll find several contractor types for insulation service, including dedicated insulation specialists, full-service energy efficiency contractors, attic insulation experts, spray foam insulation professionals, and general contractors for larger remodels. Some HVAC contractors also offer insulation upgrades. It’s important to choose a contractor experienced with Portland’s moisture challenges and knowledgeable about local energy efficiency requirements.

Helpful?

In Portland, attic insulation service typically takes one to two days, while wall or crawl space insulation may require up to three days. Whole-home insulation projects, especially those including air sealing, can take about a week. Weather conditions and permit approval from the city can sometimes extend timelines, so planning ahead—particularly in the busy summer months—is recommended.

Helpful?

Pairing insulation service with upgrades like air sealing, attic ventilation, or HVAC improvements in Portland is highly effective. Coordinating these projects can reduce labor time and maximize home energy efficiency. Completing multiple upgrades together may also help you qualify for local energy efficiency rebates, making your home more comfortable and reducing drafts, especially during Portland’s damp winters.

Helpful?

Due to Portland’s damp climate, insulation service projects benefit from annual inspections for moisture intrusion, pest activity, and ventilation blockages. Homeowners should check attic insulation for settling, ensure vapor barriers remain intact, and look for signs of mold or mildew. Spray foam insulation is low-maintenance but should still be inspected periodically, especially after heavy rainfall or seasonal changes.
