great work at great prices!
Everyone I've dealt with has been amazing! Jordan who gave me a quote, Morgan who booked my installation, Michael who installed the insulation, and finally, Melinda for payment. Quick response, professional, quality work, friendly, and great service!!!
Added blown in insulation to little old ‘house’ used as art studio & storage. Great job, completed quickly & at a reasonable price.

I have been using Master Insulation for over 7 years. There prices are always the best and service is better then most. Would highly recommend.
Insulation and gutter job on fire rebuild was done well by polite and conscientious workers. I recommend this company
Disappointing gutter installation. Master Insullation installed three gutter sections on my home on Lopez Island. I specified in my request for a bid that my roof would require gutter wedges due to the angle of our roof edges. Master Insullations estimate came back saying yes they would install gutter wedeges. I accepted the bid. The gutters they installed did have wedges, however the angle was much smaller than the angle of my roof edge. The gutters droop down. I requested that they replace the wedges with the correct angle. They replied that their supplier doesn't make wedges with a greater angle, and a larger wedge wasn't in their bid so they would not correct the installation. I researched gutter wedges on the web and found larger ones on Amazon and other suppliers. Several emails and phone calls later the best they would do is come out and swap the wedges, but I'd have to supply the wedges at my expense. I feel like a customer shouldn't have to be an expert on gutter wedge angles and supply to get a quality job.
