"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."

"Well, the was too much on the second floor but Aladdin solved that with blown insulation. I look forward to the cool savings in the summer and warm savings in the winter. The house has not added insulation since it’s manufacture in 1989. We have been here for 4 years. Should have done it four years ago. Thank you Aladdin!"

"Tim and Jeff were very fastidious in setting up, cleaning, and making sure the house was in good order when they left . We also had an Aeroseal treatment which followed with James and Connor. It did take some time to set up after the vents were cleaned and blown out, but the application of this polymer to close gaps in lthe galvinized steel ducts was remarkable."

"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."

Drywall Insulation FAQs, answered by experts

Venetian plaster is a highly durable wall finish that becomes a rock-like substance once dried, making it last longer than most other wall finishes. Its lifespan can range from decades to centuries, potentially lasting a lifetime. Key factors influencing its longevity include the quality of the initial application, whether it's properly sealed against moisture, and how the wall is maintained and treated (e.g., how often it is touched or bumped). Due to its mineral content, it can also develop a patina over time.

Plaster is a pretty tough surface, but it can still sustain damage from things like bumping against it, water issues, dampness, extreme humidity changes, and plain old age. Most plaster walls last hundreds of years and will only be taken down to the base layer when major repairs are required. Being cautious around the wall, not placing furniture against it, and ensuring stable humidity are all great ways to reduce possible damage.

Drywall anchors won’t work on plaster. Instead, they will more than likely cause more damage and pull out the plaster. The best type of anchors to use on plaster walls are the ones that will bite into the surrounding area, such as molly bolts and toggle bolts. Masonry anchors with expanders on the sides also work for lighter pictures.

It’s not a good idea to plaster over broken plaster (unless by broken you’re referring to cracked, in which case that’s perfectly fine). However, broken plaster can be a sign of a larger underlying issue like foundation damage or severe damage to the lath holding up the plaster, so it’s worth investigating before you simply plaster on top of the damage.

You can put certain types of plaster over other types, but doing so isn't always the best idea. For example, putting a coat of gypsum over lime plaster is possible, but doing so will limit the lime plaster's breathability and potentially affect its performance.

Since cement plaster tends to leave a textured surface, no matter how much you smooth it, some people prefer to use gypsum plaster as a topcoat over cement plaster, creating a smoother surface.
