"I was very pleased with the blown fiberglass insulation they installed in my attic. It's a nice, clean job with quality insulation. I had 5 quotes from companies and this was by far the best value for the job."

"Bill from WBI was the first to contact us and the first to give us a quote on the insulating of the attic and crawl spaces of our old farmhouse. The price was very fair for the professional quality of work we received. Bill is a very honest, competent, hard-working professional. He got the job done very quickly, and we are beyond pleased with the work he did for us. We can't say enough good things about WBI, and we highly recommend them!"

"We had a guy come out and assess our insulation and he was kind of creepy. The way he talked, the way he went up in the attic and grabbed a handful of insulation, showed us what was there and got it all over the couch and the floor, and he ended up telling me  that he didn't think that I needed anymore insulation. I guess he was honest and I was a bit creeped out. He didn't make a bid because he didn't think I needed any more insulation. I'm pretty certain that we would not call them again."

Insulation questions, answered by experts

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.

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.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

Insulating ductwork improves your HVAC system's energy efficiency by protecting the air from external conditions and preventing energy loss as it travels through the ducts. This means your system doesn't have to work as hard to heat or cool your home, leading to lower energy bills and a reduced carbon footprint. Additionally, insulated ducts help maintain a more consistent and stable indoor temperature, enhancing comfort. Proper insulation also improves indoor air quality by reducing the entry of allergens and pollutants and helps prevent problems like condensation and mold formation within the ductwork.

Monolithic slabs don’t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction. This can help improve home efficiency even more and keep indoor temperatures more stable. Slab foundations are more energy-efficient than uninsulated crawl spaces and basements, and insulated slab foundations are more energy-efficient than insulated crawl spaces and basements.
