"As a retired contractor I can say that these guys do it right. Estimator/salesman (Jay) arrived right on time for his appointment and sent an estimate by email within about twelve hours. Calls were returned, questions answered and proposal was clear and to the point. Appointment was scheduled with no difficulty and the crew - two very tidy men - arrived a few minutes early for the installation. (Jake and a name I did not catch) The job consisted of spraying a confined attic area which contains an air handler and the box beam around the cellar foundation. This was all done cleanly and within a few of hours. Drop clothes were placed every where necessary and the floors were covered more than adequately.  When they left, other than the work they had done, I would not have known they had been here. 

   This was a retrofit to stop heat leakage from the attic area which contains the air handler and which was causing enormous icicles over the front entrance and cold infiltration from the cellar. This was something of an experiment to see what difference the insulation will make this winter. They have other insulation services and I will be calling them to price a couple of other projects as time and cash flow allow.  Keep in mind, spray foam is lumpy. It does not present a flat  surface when finished and no one should expect it to disappear into the background unless it is behind sheetrock. That is another kind of installation.

Insulation questions, answered by experts

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.

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

A radiant barrier is a form of insulation topped with a reflective material designed to keep homes cool during hotter months. It is generally considered worth the investment if you live in a hot, sunny climate, as the cost can be recouped over time through lower energy bills. Installation costs typically range from $0.10 to $1 per square foot. After installation, homeowners in warm climates may save between $7 and $15 per month, potentially reducing their electric bill by 5% to 10%. The exact savings will vary depending on your location and the type of barrier chosen.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.
