"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.)."

"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."

"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."

Drywall Insulation FAQs, answered by experts

The amount of drywall you need for a 1,000-square-foot basement depends on the ceiling height, angles, number of doors and windows, and more. To find the wall square footage, multiply the width and height of each wall, minus any gaps from windows or doors, and add the totals together. You’ll also need enough drywood nails or screws to install the drywall correctly.

There is no way to cut drywall without making dust, but you can reduce the amount of dust and especially the dangerous airborne particles by using manual cutting tools. Using a utility knife to score and snap your drywall will minimize dust production, and a jab saw for cutting cutouts for boxes and fixtures will generate almost no airborne dust. Even if you use these methods, you should still wear a respirator and safety goggles to avoid damage to your lungs and eyes.

In many cases, installing new drywall will boost your home value. Replacing old, damaged, cracked, or wavy drywall is a great way to improve the look and feel of your home, as new drywall installed by a professional shouldn’t have any imperfections. Additionally, removing old drywall means you’ll have open walls, so you can install new insulation and address exposed issues with plumbing and electrical systems running behind the walls. All of these fixes will also add to your home’s value.

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.

Drywall insulation costs around $1,800, on average, but prices can range from $500 to $4,500, depending on a few different factors. The following things are important considerations to make when pricing out your insulation project:

  • Square footage of insulation

  • Type of insulation 

  • Climate in your area and the insulation R-value required

  • Whether or not your walls are already finished

  • Accessibility of the area 

  • Whether or not you need old insulation removed first
