Hello… I am Juan, the expert behind Capital Insulation.

My expertise in making homes more comfortable and energy efficient, is from having a construction background where my work has focused with good knowledge of industry standards and best installation practices. With experience working both with new construction insulation projects as well as insulating and renovating existing properties. Knowing what is behind and inside old walls makes a difference in knowing the optimal solution. In addition, my training includes Building Science Principles through BPI. BPI takes a whole-house approach by evaluating the air seal boundary, thermal boundary, moisture control, and internal air quality. 
Making old and new properties energy and climate efficient presents unique challenges. There is never a single solution to making a historic or old home comfortable. It requires the right combination of solutions without introducing unintended consequences.

Since 2015, Capital Insulation has been recognized as a top Insulation Contractor in Washington. I’ve provided clients with a wide range of insulation services for all their remodeling and repairing needs. Whether you’re looking to renovate your existing space or add a whole new extension, I’m happy to help you achieve the results you seek. Contact me today to receive a free estimate.

Review by David Z. in Federal Way, WA

Comments: Best experience I've ever had with a contractor. They not only performed outstanding, when I contracted Capital Insulation for an estimate, I contracted 3 others, Juan called on the day and time he was expected, he said he was running a little late due to traffic, and would be at our home in 5 min. He arrived in exactly 5 min and his estimate was the best, not only in quality of his inspection but in his presentation of his findings. I was so please and impressed with his work that I've contracted him to do some additional work. Couldn't be happier. Would highly recommend Capital Insulation to everyone.

We encourage people to visit our Google, Thumbtack, Homeadvisor, Yelp! and other review sites. We do our best to ensure that the work is done right and if something doesn’t go quite right, we come back and make our customers happy.

Great job! Great in every aspect! He is responsive for our questions before the project started, arrived on time, minimal disturb while setting up the blow machine, take pictures to explain things well, never upsell things, did extra work without changing original price. Very professional insulation removal and installation. Last but not least, his price is the best! Strongly recommend!
