"The owner of the company did my estimate, and was wonderful in explaining things, and at no point did I feel I was being up sold or steered in any direction. The two installers were pleasant, quiet, worked clean and quickly. They left the house as clean as it had been when they arrived, and I am already appreciating a change in the air temperature in my upstairs. I would completely recommend Superior Insulation."

"The two gentlemen (for lack of better term) installers, were polite, professional, and got the job done. I was very happy how they put plastic around and if they moved something they put it back in its place."

"Jag installed spray foam in the basement, air sealed the attic, and sprayed fiberglass in the attic. The work was done as scheduled. The obviously experienced crew was fast and friendly. The cleanup was great. I definitely would recommend Jag."

"Mark was very professional and gave a complete explanation of the estimate and work involved. while only one man showed up on the date scheduled for insulation, he completed the exterior walls foam insulation work including the interior basement rim in the day as promised and was very courteous and thorough. I have noticed quite an improvement in the warmth of my home and especially since we have had 2 very cold weeks since Christmas. negative degrees! I am very pleased with the company and the work."

Insulation questions, answered by experts

Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems. In many cases, you can insulate plaster walls, while in others, it's a poor decision because of the lack of a vapor barrier. Choose a reputable insulation contractor to help you decide if and how to proceed to increase your home's energy efficiency.

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.

Spray foam is a highly effective insulative material that can dramatically reduce your energy bills and create a more comfortable living space. It does have a couple of drawbacks, however. First and foremost, spray foam insulation is much more expensive than fiberglass batt insulation. In addition, spray foam insulation is a dangerous chemical material; this is a project that is best left to pros for proper and safe installation.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

While fiberglass is dangerous to work with, it’s a perfectly safe material once it’s installed. If you’re tackling the installation yourself, make sure you take the proper safety precautions and wear the right gear to avoid skin and eye irritation and lung complications. Working with a professional insulation company can mitigate these risks.
