"The staff was friendly and professional. They demonstrated a desire to get to work asap which made the selection easy. Also got a spray foam insulation bid for crawl space and we will go with SPF for this large expense. Spay foam crawl supports our heated floors so that more heat will heat people opposed to rats in the crawl..."

"Insulation Co (Jo Estrada) had insulation installers come to our century old house to remove old attic insulation, do a bit of mold remediation, insulate the bathroom fan exhaust, cover the two previously open gable spaces at either end of our roof, then blow in new cellulose insulation. All this took a day, and all was cleaned up like nothing happened. Polite, efficient, professional, and the price was competitive."

"I was given several recommendations from Angi list, the most professional one of the 4 contacts I received was from David of EVERGREENPRO INSULATION. I needed to have a couple of interior walls insulated for soundproofing done. David was responsive, answered all my questions and gave me a reasonable quote. The other companies I talked to quotes were inline with Davids but the customer service just wasn't there like Davids. I even had one company tell me my project was too small for them to do..... Really? The next insulation project I need done I will just call David from EVERGREENPRO INSULATION and give them the job. A great job done by David and Jamie and would recommend and use them again."

"It went very well from the estimate process. Rory took the time to explain the process. As I had questions, he took the time to talk to me and explain in detail. Deb coordinated the scheduling extremely well. Among the estimates I got they were the most reasonably priced. I started out only doing the attic. They did such a good job, I decided to go ahead and have the crawlspace insulated as well by Madrona Insulation. BTW, shout out to a terrific installation crew!"

"I hired Acorn Attics to insulate my house and I couldn’t be more happy with their work. Phil and his crew were on time, friendly and incredibly hard workers. He worked with me on scheduling and made sure to keep our project moving even when we had a setback with another repair. I highly recommend them. They will get the job done. Thank you Acorn Attics and Crawl Spaces!!"

"My 1959 home with unique siding presented specific challenges on this job. Some of the plug work done was PERFECT, and much of it was not, resulting in unsightly exterior appearance and challenging sanding and finishing being required by me, the homeowner. This company COULD have done all the plugs perfectly, but chose not to do so. In addition, I had to request a receipt for the work, and I was not provided with a written copy of the verbal warranty stated by the owner of the company."

They took the time to listen attentively and analyze the problem, ensuring they fully grasped the unique challenges of my property. This attention to detail instilled in me a sense of trust and confidence in their ability to provide a customized solution.

Their expertise was evident as the very beginning they knew the exact insulation requirements of my property, leaving no stone unturned. Their attention to detail and commitment to excellence were truly commendable. What truly sets this insulation company apart is their ability to provide tailored fixes.

Their personalized approach ensured that every aspect of the insulation work was precisely tailored to maximize energy efficiency and cost-effectiveness all within a very competitive price. I genuinely believe they are the best choice in Washington."

Insulation questions, answered by experts

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.

Depending on the item, several different materials are beneficial for long-term storage. Bubble wrap and plastic wrap help ensure delicate ceramics or furniture are safe and secure. High-quality moving boxes made of durable materials like plastic also help ensure the longevity of your storage, as cardboard will degrade faster over time.

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.
