Owner John came out to provide us with a quote for a smaller job in the crawl space beneath our kitchen. He was very friendly, gave us a reasonable offer, and informed us about energy rebates that would expire at the end of the year. We booked the job. The crew arrived promptly and got to work immediately. Our crawl space is not easily accessible (through an old hopper window located over the utility sink in our laundry room). They cleared out the old insulation and cleaned up years' worth of detritus. They were finished in under two hours and left everything tidy. Clear before-and-after photos were shared with us. Great work! We can't wait to reap the benefits of a well-insulated space.
I had Koala spay foam my cathedral ceiling that lacked any insulation. Guys came on time and performed the work within guidelines. Area was prepped and sprayed well. No funny residue and was able to return home the next day. I was very pleased with the workmanship, quality and attention to detail. My AC unit no longer runs as often as it did. Now I can’t wait how this will perform in the winter, but I can already tell a drastic difference in temperature. I would highly recommend.
Koala insulation came through for us. We wanted to have or attic insulated with blow in material John Anthony came and gave a quick quote. He showed us what they were going to do and gave us a fair price. The job was scheduled right away. The team came on time and left the house as clean as it was when they got there. It has not been too cold yet this year, but we can notice a positive improvement. No drafts or cold ceiling now. 18” deep throughout the entire attic. They gave us very good complete pictures of the before and after of their work. Very satisfied and will recommend them to others.

ARC recently completed an insulation project in my home that was built in 1862. The home had zero insulation in the attic. We worked with David and his team and they were absolutely fantastic. Super professional and a pleasure through the entire process. My home is super cozy now! I highly recommend ARC.
We had our old attic insulation removed and replaced, and the entire experience was excellent. Steve Garrett was our main contact. He was personable, experienced, thorough, and responsive. We appreciated his immediate responses to any questions we had. The crew that completed the work was knowledgeable, detailed, hardworking, pleasant to interact with, and worked well as a team. They took pride in doing the job right. Since the installation, we’ve noticed a huge improvement in the warmth of our home, and our furnace is no longer running constantly. We’re very pleased with the results and highly recommend Arc Insulation.
Box sills were insulated in October. My home had a mouse problem for the past couple of years and paid a Pest Service (all they did was put bait boxes outside). Found information to insulate your box sills where the small leaks are allowing cold air and pests to come in. Wish I knew about this solution before. Now, absolutely no evidence of mice, spiders, webs, small bugs..... All perfectly and expertly sealed. Basement is warmer and less damp and wood floors above are warmer. ARC Company was excellent. They were easy to talk to and the crew was helpful and knowledgeable. Everything was sealed off and debris expertly removed . Old insulation had some mold AND dead mice.... UGH!!!! Everything was cleaned up and installed perfectly. Crew was professional, courteous and outstanding.... Wasted too much money on Pest Service and should have insulated with ARC . Highly recommend services and crew. Money well spent for great services and results.

Innovative Insualtion Solutions are the best. They sprayed closed cell foam in our open attic spaces. Communication prior to the project beginning from the office regarding timing and how the job would go was excellent. The crew sent over to my home were even better. They communicated well, showed up on time each day and were respectful of my home...three things that I, as a small business owner, can really appreciate. The owner, Richard Spies, also showed up onsite to make sure all was well and to answer any questions that I had. A really great experience from start to finish. I would highly recommend them for any insulation work needed in your home.
Great communication, easy scheduling, fair pricing. Richard was great to work with and his team was friendly, clean, and efficient. We got 3 quotes for insulation and thIs was by far the most reasonable. We saw the difference in our energy needs almost immediately - we would keep the thermostat at 73 and our bedroom upstairs would not get warmer than 68. After the insulation was added the room temp is exactly what we set the thermostat to. Glad we did this before winter began. Would definitely recommend this company to friends and family.
We recently worked with Innovative Insulation Solutions, Ltd., and I couldn’t be happier with the results. From start to finish, their team was professional, knowledgeable, and efficient. The crew arrived on time, worked neatly, and made sure every detail was done right. Home feels noticeably more comfortable, and the quality of their spray foam insulation is outstanding. It’s clear they truly care about their customers and take pride in their work. Highly recommend them to anyone looking for reliable insulation experts!

Absolutely outstanding work from beginning to end! The project manager, Javier, did a fantastic job. The project involved the removal of old insulation from the attic and walls of one room. From the initial planning, execution of the project, to the final cleanup, everything was handled professionally. I highly recommend this company for their excellent service.
Echo Tec is responsive, professional and efficient. They did a wonderful job with my home insulation.
It was a pleasure to work with Brian, Andrew, and their family business. I recently had Eco Tec at my home doing wall cavity insulation. My house is over 100 years old and largely stucco exterior, both of which present more challenges, but they were able to do get the job done mostly from the outside. I only had a short turn around time for completion of the work, repair, and clean up. Brian went above and beyond to get my final clean up done by my required deadline - thank you Andrew and Ryan. I want to acknowledge Ruben for his efforts and thorough work getting my drywall repaired, painted and back to normal. Brian is very responsive and has such a friendly, calm and competent attitude. I thought my initial quote was very reasonable considering the scope of the work. My final invoice and payment due amount was really good value. I would definitely recommend Eco Tec Insulation.
