Get matched with top insulation pros in Longwood, 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.)."

"Jeff was great to work with and I highly recommend him to anyone looking for insulation work. He was knowledgeable, honest, and performed high quality work. I will be using Jeff again in the future for more insulation work!"

"Dennis and his crew are awesome! I called Dennis because I had condensation coming from an electrical outlet in one bedroom. In addition, my pantry and closets would always feel humid and warmer than the rest of the house. He came out and diagnosed the problem in an honest, professional manner: it turns out the builder of my house never did the air sealing under the attic insulation, so he took care of that. I also had him do wall-injected insulation on the wall that is hit by the sun all day, as well as add more attic insulation for energy efficiency. Dennis is responsive, knowledgeable, and won't sell you stuff you don't need. I'll be recommending him to neighbors who have houses built by the same builder, and who probably have the same problem I did."

"Fair price an on-time service. But I should have checked the job..... there were a few spots in the attic that did not get any insulation. (not the garage..... that does not need insulation..... but a few spots over heated space were not covered). But their price was better than other estimates. I also requested the chemical that detracts rats and mice..... I do not know if it was included...... I hope so."

"Added insulation to my attic. Very nice and professional. Job well done! Could not be happier ☺️"

"My house has never been properly insulated and Jeff was very kind he knows my tragic losses and was very comforting and bless me. I told him I would recommend your company to anybody in my neighborhood who has not had insulation like myself. I’ve been here close to 40 years and I will continue to honor your name for quality work and professionalism. That deserves a commercial I recoup my expenses on my commercial with you people."

"Matthew was very friendly and professional and thorough with his evaluation. He provided information on the company and readily answered all questions. The insulation was blown in and the workers took care to clean up when they were done. I highly recommend this company for the job."

"They did a great job no waiting time. I will recommend them to my friends and family with no daubs. Job well done in no time. Thank you:"

"The owner is the installer and takes great pride in his work. The job started and finished on time. I highly recommend King Insulation."

"Dennis was very professional. Came on time and took pictures before and after insulation. Cleaned the floor that they left some debris."
