Very professional. Provided free estimate over the phone and came out to complete the job two days later. Quick but thorough. Took great care of our house and cleaned very well afterward. Love that they provide before and after pictures. Now we are SO much more comfortable in our home. Previously with the summer heat, our brand new AC unit couldn’t keep the house cooler than 78 degrees. We had to turn the temp to 78 when leaving, otherwise it would get up to 84 in the house. Now, it’s able to maintain a perfect 72 in the house. We’re saving a little on electricity, but SO much more on our

The people at Insulation Works, Manny and Mari, are very friendly and very professional. They showed up when they said they would, they did the work they said they would, and cleaned up as they said they would. Add to that excellent rates and customer service, and you've got a winner. Highly recommended!

Insulation works did an incredible job! They were able to give us a quote via phone, sorted our CPS rebate and rolled that into the cost. They also went above and beyond in the job they did, clearing out rubbish other contractors had left, adjusted old batt insulation, used corner and floor protectors to insure they left our attic and our home in the best condition possible. Manuel and Mari are a lovely couple and a great team, I would trust them with all of my insulation jobs in the future.

Very professional and responsive. Insulation does work! My house is 21 years old and I have tried many things to help keep the house cool. My kids don’t complain of a hot house ever since Manuel and Mari installed insulation. I highly recommend them!

After searching for the best attic insulation option for our hot difficult/low pitch attic, we found Manny and Mari! What great advice and outstanding work they did. They offer many choices, and won’t try to sell you on a product their experience knows won’t help. We had several other companies that gave estimates and promises, but Manny is a straight shooter and won’t lead you wrong.
We ended up with several extra inches of blown in insulation and are very happy with the decision. He found ways to get to areas of the attic other companies wouldn’t look at.
This team is extremely conscientious

Summer is approaching along with the intense heat. I was overdue to update insulation in my attic so I reached out to several contractors. I cannot recommend highly enough the amazing Contreras Family at InsulationWorks. This is a family owned & operated business and they are a friendly, first class provider. From the initial inspection, explanation of work to be done, installation day and even post-installation follow up were unmatched by most service providers I have experienced across many industries. If you value integrity, hard work, exceptional results, and simply a great experience, put

Manny and Mari did an outstanding job re-insulating our new home! They did an exceptional job answering any and all questions I had regarding insulation. We must have talked for a few hours about what the best option would be and why this was the case.
One of the great things about this company is that they don’t subcontract their work. You only deal with Manny and Mari throughout the whole process. I believe this is also why their prices were much more competitive than other insulation companies in San Antonio.
I did quite a bit of research regarding insulation prior to hiring them and I read

It was a pleasant experience working with Manuel and Mari. Manuel is knowledgeable, courteous and meticulous. The attic was brought to the right grade with high quality blown-in insulation. Knee walls and attic closet doors were also lined with batt. Manuel replaced the weather stripping of exterior doors to improve insulation in our house. They covered the floors and stairs with cloth liners for protection and area was left clean when work was finished. They took care of the CPS rebate and discounted it from my out-of-pocket total. They also gave me the option to pay for the job in installments

I had rats in my attic and wanted to replace the soiled insulation. I called several companies and was quoted some outrageous prices! Insulation Works quoted me the best price, and went above and beyond in their service! They blocked off the holes where the rats came in, caught all the rats, fumigated, sanitized and deodorized the whole attic. They put the new insulation in once they were sure all the rats were gone. I can't speak highly enough about Insulation Works! They are amazing!!

When I hired Insulation Works to install additional insulation in my attic, I mentioned that I wanted to put a additional vents in my attic space. The individual performing the estimate told me they did that type of work also. A few months after the installation we found a roof leak below one of the vents installed. I did not trust Insulation Works to come back and attempt to fix my roof so I had a roofing company come out and provide me an estimate for repairs. The roofing company told me that Insulation Works had installed all three vents incorrectly and after doing some research on the internet
