5.0 Steve M. Winter Garden, FL

The guys showed up on time both days. They explained the process step by step and answered any questions I had. They were very flexible with schedule once I ran into electrical issues in the middle of the project.

Very professional and informative

5.0 Tj T. Orlando, FL

I have been trying to get some answers on how to improve my home's efficiency and especially find the best solution for my attic insulation as my power bill is quite high! Derek and his team were absolutely amazing! Derek figured out what I needed and made everything happen quickly and for an amazing price! I would strongly recommend Capstone Insulation to anyone!

5.0 James N. Lake Mary, FL

Excellent work; on-time; great workers (Derek, Raul, and Ken) I had my 43 year old home reinsulated (I'm the original owner). Derek took time to explain all expects of insulation -- no rush. I would recommend Capstone Insulation highly. Keep up your great work.

Thanks Jim! We loved working at your home!

5.0 Donald S. Winter Park, FL

Replaced 30 year old rolled insulation covering the metal ductwork on our AC system which is located under our house. They provided video from the hard to reach crawl space that showed the problem areas that needed repair. They fully explained the suggested problem solving approach. They also undertook additional improvemzents to the metal areas prior to installing the insulationâ ¦.work was completed on schedule and at a very competitive price.

5.0 David S. Orlando, FL

DERIK, Raul and sons are a great team. Derek did an excellent presentation on the two different types of insulation and pros and cons. I had the full ceiling blown and door test with excellent results. They took care of all clean up and I well pleased with work ethic and professionalism. Thanks job well done.

5.0 Keith B. Groveland, FL

This work was performed in Groveland, FL, 34736. Capstone Insulation was great. The VP came out, went through the attic, and described the work to be done. This included thermal imaging to find air transfer locations, air sealing between the attic and living spaces, installing baffles over the inside soffit vents, installing and air sealing recessed lighting covers (for fire safety), installing new insulation, and pre- and post-insulation air flow testing. The installation crew was very competent and friendly. They performed the initial air flow test and all the pre-insulation work on day 1. They came back the next day to install the insulation and perform the final air flow test. The VP provided me with a video of the Day 1 work and a video of the final outcome. All of this work was done at a price point that I thought was reasonable (about $2/sq. ft.).

4.5 Natalie J. Winter Park, FL

Everyone was very pleasant to work with and they did a great job. I appreciated the thorough initial inspection and the air flow checks before and after insulation.

Response from Company:

Thanks Natalie!

5.0 Sarah J. Winter Haven, FL

Not only did a great job adding insulation to my attic and sealing around vents, they did a blower door test that was very helpful to find where my house was leaking. He then gave advice on cheap and easy ways to seal leaks around windows and my sliding doors. Guys were very polite and professional. Would highly recommend!

Response from Company:

Thanks Sarah!
