"FoamCo recently insulated our basement walls. Before, we couldn’t use the basement in the winter time. We noticed an immediate difference once the insulation went in, and now our basement is our favorite cozy hangout spot in the house. They were great at explaining exactly what kind of insulation I needed and were actually the best priced bid we got."

"We had St. Louis Insulation seal and insulate the crawlspace in our one-story 3-bedroom brick home in early December. The existing insulation was probably original from the mid-70s and was falling from the ceiling of the crawlspace, about half already on the floor. SLI provided an estimate and described their procedure -- sealing, not just replacing the rolls of insulation but sealing the floor and walls and vents. They described the timeline for the work. The estimate was pricey, but well in line with other providers of the same service, and it's a one-time job, not an every-20-years job. Ultimately we selected SLI as we were impressed by reviews of their work and by their professionalism and the clarity of their description of the work to be done. They arrived punctually and performed the work very fast, considering the nature of the work (removing all old insulation and all the other debris down there, putting in the new plastic and insulation and foam spray). I was very impressed by their politeness, efficiency, and the cooperation they showed in working together. (They're in the crawlspace and so if they had yelled or even been grumpy with each other, I'd have heard it.) They removed approximately 24 very large stuffed trashbags of old insulation (it's a large crawlspace) and stacked them neatly on the driveway, then put everything in their truck and hauled it away. (That was the first day.) They brought in the supplies of the new work -- holy cow, lots of plastic, tanks for the foam spray etc -- and quickly installed all of it. (That was another half-day.) They supplied photos of the work so that I didn't need to get into the crawlspace to see what they'd done. The work was fully completed within the time they had estimated. And everything they did was cleaned up. I would recommend, without reservation, their work. Great people, very professional, and they clearly have done this enough that they are very well organized. Because the entrance to our crawlspace is in the floor of a bedroom closet, they kept that bedroom closed while they were working, and took everything in and out via a window. It kept any mess localized, so that I did have to do a thorough cleaning of the carpet and all surfaces in the room but it was only one room, and I was cleaning the dust basically -- all their supplies and any trash were totally removed. So A+ on that. One small unforeseen issue was that we have small dogs, and we had not thought about the spray foam and any fumes, and SLI did not think of that either, until the day they were going to do the spray foam. We had to quickly move the dogs to another part of the house, and near a window, where they would be less exposed. (They're pugs so I think the fumes would not be an issue for a larger dog -- we just need to be careful because they're pugs.) If you have small dogs, or pet birds, you will want to consider how to keep them safe during the foam spray. Overall, St. Louis Insulation did a great job. They said exactly what they'd do, and they did it. Considering the nature of the work required (bending or kneeling in a crawlspace, hauling huge bags of old insulation and rolls of plastic while bending or kneeling), I am hugely impressed with the professionalism and with their good-natured attitude. They are very good at what they do."

Insulation questions, answered by experts

Yes, there are government incentives available in some regions for insulating air ducts as part of energy-efficient upgrades. These incentives aim to encourage homeowners and businesses to improve energy efficiency and reduce their carbon footprint. To determine whether you qualify for such incentives, check with your local utility company or government agencies. They often offer rebates, tax credits, or other financial incentives that can help offset the cost of duct insulation projects.

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.

Insulating a stone house is an expensive and involved process because it requires building a double-walled house. The walls don’t need to be the same thickness, but they both need to be thick enough to handle any structural demands and meet fire and safety standards. The insulation (usually foam or fiberglass) is then installed between the two stone walls.

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

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.
