"Professional crew; work was done quickly, with minimal disruption and fairly good cleanup. The house is older and the crew chief took reviewed the interior carefully to insure there would be no damage to the walls in the insulation process."

"We had this company come to do insulation for our whole home - attic and walls (through Mass Save). Not only did they do what was in the original contract, but they also added insulation to our garage ceiling AND to an open wall that was being worked on for an unrelated home reno project! They did 3 days of work in 1 day & stayed late to vacuum and clean up. They were very professional, extremely efficient, and I love that it's a family operated company. Ivan, their office resource who helped book the appointment, was also a pleasure to work with throughout the process. We highly recommend using this company for any insulation needs."

"Installation of insulation went well; EZinsul was very thorough. However, there were some clumps of insulation and a thick film of fiberglass covered everything, despite their sweeping up to â industry standardsâ . Jacob & I talked; he came back and dusted to my satisfaction. I appreciated this attention he paid to my project. I would highly recommend EZinsul. Ruth Ann White"

"I unfortunately did not get to actually use them other than investigatory work. They were timely in response, despite it being a small job. They ended up popping a number of shingles and drilling a bunch of holes, but there was old insulation behind it. They did not want to pump blow more insulation in because they said it would just create air pockets. They did not charge us for the investigation."

Drywall Insulation FAQs, answered by experts

When sanding drywall mud, you’re going to create a very fine dust that may contain silica. Silica dust contains crystalline silica, which can cause long-term illnesses for people who inhale it in significant quantities. Wear a mask while sanding drywall. Then dampen a drywall sponge to wipe the dust off the drywall, helping to reduce the amount of dust that may become airborne.

You can paint over plaster, but repair any damage to the plaster first, or the paint will crack and bubble. You should also prepare the surface of the plaster to accept paint, which gives your paint job the best chance of looking good and lasting a long time. Before applying the color you want, apply a coat or two of primer. Additionally, use latex paint, and choose a latex paint with a satin finish for areas with dampness, like bathrooms.

If your home was built before the 1940s and was not remodeled in the past 50 or so years, you probably have plaster walls. Aside from assuming, there are some practical ways to tell if you have plaster walls, including the following: If you knock on the wall and it feels solid, not hollow, if you can’t insert a thumbtack easily, if there are cracks that look like spiderwebs, or if your home has curved, arched, or swirled walls, doorways, or window openings.

If you have an unfinished basement or attic, you could examine the backs of any finished walls to check, too.

Choose a drill bit that is the size of the screws of the anchors you will use. You aren’t drilling through metal or concrete—hopefully—so any standard twist, wooden or all-purpose drill bit will work fine. It’s also important to have a screwdriver capable of drilling through the drywall and into the stud. The good news is most available drills, even the older ones, can do this with no issue.

Mudding drywall is a DIY-friendly project, but patience and practice are required for perfection. If you’re working in a highly visible area and want the best possible finish, hiring a professional drywaller is worth the cost. Pros have the tools and know-how to ensure a smooth surface with fewer sanding sessions and less cleanup.
