“We noticed a huge difference in the comfort of the home immediately, particularly on the second story. I am an HVAC contractor and I would highly recommend anyone bring their insulation up to code in the attic and the exterior walls as it will significantly reduce the use of your air conditioner. I have referred several clients to Guardian and they have all been very pleased with the results, the quality of work and the crew. They even used special equipment to insulate our cathedral ceilings which most contractors could not do. I would highly recommend them to anyone who lives and an older home.”

With the programs that are available for solar these days I jumped on board. I ended up getting solar, a whole house fan (which we are living right now) a tankless water heater, full insulation throughout the entire house and my payment is less than what I was paying for my electric bill prior to having the work done, AND no money out of pocket at all. I also got several rebates upwards of over $1,000.

“It’s shown a remarkable difference in the overall costs for our heating and cooling. I would certainly highly recommend that you use Guardian Insulation to have your home insulated. I was really happy with the company and the services they provide. And I feel it was well worth the cost.”

“They did a very quick and professional job, left everything nice and clean. The gas bill and the electric bill have gone down. I would definitely say it was worth the investment if you’re planning on staying in your home, absolutely I would recommend it.”

“We noticed a dramatic difference…it was extremely warm and now it’s very bearable. Also with the colder weather in the mornings it’s much warmer. The people who did the work were extremely professional. We are very happy with the work they did. When they patched the holes they turned out perfectly. You couldn’t even tell that they were ever there. And overall we are extremely pleased with the product and the results of insulating the house.”

“They did a great job. We were extremely impressed, particularly with their ability to match the stucco. The paint is quite impressive. They came on time and they cleaned up and we’re very happy we had it done and it’s quieter than it used to be.”

“Our house feels 100% better! The furnace barely runs now and when the AC runs the house feels cooler and more comfortable. The patching and painting of the walls is so good you seriously cannot see where the holes were drilled to fill the walls. We are very happy and recommend Guardian Insulation.”

“They were quick to respond to our inquiry. Jesse, the salesman, was professional and easy to work with. He even came by to check on the progress of the installation and to make sure it was to our satisfaction. The installer, Mark, showed up on time and was prepared. He protected our floors, walls and furniture, and completed the job on schedule. Clean-up was thorough.”

“Jesse was great at explaining what needed to be done to fix my issues with excessive heat. He helped me get qualified for the HERO program which allowed me to get the work done that I needed. Mark came out to do the work. He was fantastic and went above and beyond with paint matching and even fixed some pre-existing paint match issues that I had. Overall I am extremely satisfied with the service I received and would highly recommend this company.”

“Guardian insulation was prompt in responding, Jesse is a great promoter for the company, his presentation was on spot. Mark, he is on the job when he is suppose to be and is an artist in matching the paint and doing patchwork, he made the holes look like they were never there. Great job!”

“Jessie was a lot of help. Honest and to the point. A/C ran all day before the work. Now cycles on and off during the high heat of the day. Will pay for itself. Great job!”
