"This is the second time I have hired L&L. They work fast, clean, and they know their stuff. I was wanting to insulate my vaulted ceiling that I suspected had very little insulation in it from the house being built 30 years ago. Other contractors wanted to rip all the drywall down to install but L&L said they could do a packed insulation that would warm the space and be air tight to avoid condensation issues. I have noticed a huge difference and at a fraction of the cost of others. I already have them lined up for another insulation project in the basement."

"This could not have gone any smoother. Despite having to re-schedule the original, 1st quoting appointment, Darren was here the very next day. I had a quote by the end of that 2nd day/appointment, was scheduled the next day for the following Monday and the 2-person team was in and out within 90 minutes. My kids didn't even wake up(granted, they could sleep thru the emergency siren!) but wow. My attic/crawl space is now fully insulated! All this while we are adjusting to our new normal of social distancing and heightened sanitary measures. I would use AFI again and would recommend them based on this experience."

"The bid was to increase my insulation factor to R38,check that ventilation screems in roof soffits were open, and to cover any open holes before the insulation was blown in. The work was performed in a neat, timely, efficient manner for the amount bid."

"Abraham and his team came out and completed our insulation project in -17° weather. My wife and I are thrilled with the finished product and the job that these guys did. We would definitely recommend them and would hire them again in the future. We have bedrooms above our garage that were 15° colder than the rest of our house so we had Abraham give us his expert opinion on what needed to be done to warm up those bedrooms and our garage. Only after about an hour after his team left, we could already feel the temperatures rising in both the bedrooms, and the garage. Can’t thank them enough for their hard work!"

"Prevailing came in to insulate my basement and attic. The workers were professional and worked the entire time they were here (which seems like a low standard, but I've had situations where 4 people come to work and 2 stand around talking for most of it from other companies). More importantly, they explained what they were doing as they did it, and cleaned up after themselves before they left! Scheduling the service was quick and easy since they were able to use our Alliant Energy quote to avoid a second home assessment, and they came in under budget. Very satisfied - plan to have them back to blow insulation in the exterior walls before winter."

Drywall Insulation FAQs, answered by experts

You can plaster over regular drywall, but it's essential to prepare the surface properly. Before plastering, the drywall should be clean, free of dust, and any loose or peeling paint should be removed. Applying a primer specifically designed for plastering can improve adhesion. Some professionals recommend applying a base coat of plaster or joint compound to create a better surface for the plaster to adhere to. Proper preparation ensures a smooth and durable plaster finish over regular drywall.

A nail in drywall cannot hold very much—usually only a few pounds. A nail in a stud can add support and hold around 20 pounds. If you are trying to hang something heavier, get some help from drywall anchors—toggle bolts are very strong and able to withstand more weight.

There are a handful of reasons why your drywall anchors are breaking. Using the wrong type of anchor is the most common problem, so always make sure you’re using the best option for a particular project. That there are electrical wires or plumbing where you’ve placed an anchor or that your drywall is weak are two other possible causes. 

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.

Yes, you can apply new plaster over an existing plaster surface, such as a wall or ceiling, provided the old plaster is in good condition. Before you begin, check the stability of the existing plaster. The surface must be clean, free of loose material, and have no peeling paint. It is also recommended to roughen the surface slightly to promote adhesion. For older plaster, applying a base coat like a PVA emulsion or a specific bonding agent or primer is crucial. This step makes the existing plaster less porous and ensures the new and old layers adhere properly for a smooth, long-lasting finish.
