How do I add insulation to existing walls?

• <div><p>If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install <a href="https://www.angi.com/articles/blown-in-insulation.htm">blown-in insulation</a>. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than <b>$100</b>. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.</p></div>

When is the best time to insulate a garage ceiling?

• <div><p>The best time to insulate a garage ceiling is when the weather is mild and dry. That means it shouldn’t be stormy, snowy, or raining, and the temperatures should be comfortable. Ideally, you’ll insulate your garage ceiling in the fall, before winter hits. Not only will you be the most comfortable, but you’ll also likely see the greatest energy savings heading into the colder weather with a newly insulated garage. </p></div>

How much does it cost to have insulation installed?

• <div><p>The average <a href="https://www.angi.com/articles/how-much-does-insulation-cost.htm">cost to install insulation</a> is around <b>$1,800</b>, but you could pay anywhere between <b>$500 and $4,500</b>, depending on various factors. Some of the things that have a significant influence on your pricing include the following:</p><ul><li><p>Size of the area </p></li><li><p>Type and R-value of the insulation </p></li><li><p>Whether your space is finished or unfinished</p></li><li><p>Accessibility of the area</p></li><li><p>Your geographical location</p></li><li><p>Amount of site preparation, especially for blown-in insulation</p></li><li><p>Whether or not you need old insulation removed</p></li></ul><p></p></div>

They were very professional, took care of helping me get the home energy audit and the rebates for attic and wall insulation. Also improved attic ventilation installing soffit vents and baffles. We got three estimates and they were a very good price, but the service is what sold us.
