"They came on time, did the job, cleaned up, and left. They knew we had an attic door in the doctor's exam room so they entered thru the garage attic door but when they blew the insulation in, they didn't cover or protect the other attic door. Insulation fell in thru the cracks all over the technician who was working with the doctor. Since they knew the door was there I wish they had kept insulation from flying in. Otherwise I think they did a great job. It certainly made a difference in the temperature of the building on hot days."

"My wife and I were very pleased with the team that came out to install the MILO Insulation at our home. We found them to be very professional and courteous. They worked quickly and quietly to install the MILEX insulation and cleaned up after themselves. Overall it was a fine job. We would highly recommend MILO Insulation of Texas â Denton."

"I live in a old house, and the insulation on the attic needs to be added.  City of Austin Utilities (Austin Energy) has a great rebate program for insulation, so I signed up.  EnergyAttic is one of the companies listed by Austin Energy.  For getting the quote, the audit person was friendly and through with his explanation about what's and why's.  Finally I scheduled for the work.  Kent came with his crews and basically supervised and worked on the problem and the insulation.  He made sure everything was installed (seal, insulation) properly and Austin Energy auditor approved the work.  The door blower/blast test took a while because of setting issue (EnergyAttic subcontracted to other company), and finally after 3 hours, we did get an excellent result.  I was happy with Kent's and his crews work.  They were friendly, punctual, and got the work done.  They actually came back to reseal door on the furnace area.  They also promised to come back if  I were to work on the attic and the insulation needed to be re-sweep."

"Replacing your regular insulation with spray foam from iFoam was a great decision. The crew did an outstanding job removing the old insulation then spraying in the new. August in an attic is not easy work!! Thorough and courteous group of guys. I will not lie, this was not a clean process, but iFoam did their best to mitigate the mess and then cleaned up when they were all done. Would highly recommend iFoam for your next insulation job."

"Those people were great. I knew them by their names because I knew them. They were actually recommended to me by the company I hired to add insulation to my attic. They told me about these 2 guys that had the business. I told them that I re-caulked my house every 2 or 3 years and they mentioned these guys to me. I called them and they came out; it was a father and son. I went around with them and they showed me what I have been doing wrong. It was roughly half of their retail price I paid. It was a big deal purchase. They had a special on the window sills; the normal caulking around the windows. The people I bought the house from had a glazing company come in and replace some of the windows with the wrong thickness of dual pane glass. The aluminum frame was made for one-half inch think dual pane windows. It was ready made in the factory. They put in three-eighths so I had an eighth of an inch gap about 4 of my windows. The seal had been compromised and there was fog inside the windows. I had the previous owner fix all that but he did it with the wrong glasses. Rhino Energy Solutions showed me that problem. Then I had him go in with a life time silicone caulk which is different than the normal caulking they use. He did the best fix he could do; it was short of replacing the window for all of the ones that was installed wrong. Two of them are in the living room. My wife and I immediately noticed that the amount of cold air blowing in from the north windows was reduced by them doing that. I had no idea that I even had that leak around the window. It takes somebody who knows glasses to see that there was an error over there. They did this in the same week I went from a 9 to a 39 R rating in my attic. It wasn’t possible to figure out how much I saved on my electric bill because of the caulking. I could feel the difference in the house. I went around with the father and the son and watched them do everything they did. They were pretty careful. This craftsman was willing to teach me part of his trade. I have been caulking my home myself since I bought it. He showed me how important it was to dig out the old caulk. He told me putting new caulk over old caulk doesn’t really work; it may be aesthetic. Their responsiveness was excellent. They showed up when they said they would be here."

Drywall Insulation FAQs, answered by experts

If you suspect black mold is inside your walls, do not punch a hole in the drywall yourself to look. Call a mold inspection expert to help you. Some signs of a potential black mold infestation inside the wall include an unexplained musty, damp smell. Some people liken it to rotting vegetables. You may smell it most strongly through a wall outlet. If you and your family are experiencing constant coughing or symptoms that feel like an unexplained allergy, it could indicate black mold behind a wall.

A common cause of separation between a wall and the ceiling is truss lift—this can happen to the ceiling of rooms directly under the attic when the seasons change and wood building materials dry out, shrink, and shift. Roof trusses often dry out at different speeds, and if the bottom pieces dry out faster than the top pieces, they can shrink and pull the attached drywall away from ceilings and walls, causing cracks. Fortunately, truss lift is only a cosmetic problem, not a structural problem, and you can fix it by separating the ceiling drywall from the roof trusses, and patching the cracks.

Plastering lasts for around 15 to 20 years without needing repairs or maintenance in most cases, and with proper upkeep, plastering can last a lifetime—sometimes more than 100 years. Plaster repair costs between $1 and $3 per square foot, and you may need these services once every 15 to 20 years or so unless you have a harsh climate where humidity changes are a constant issue. You can also opt to skim-coat plaster for between $0.90 and $1.30 per square foot, which may serve you better in the long run.

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly. 

Both plaster and drywall are durable wall finishes, but they differ significantly in installation, cost, performance, and aesthetics.

Installation & Cost: Drywall installation is faster and more affordable, typically costing $1.50 to $3 per square foot. It uses premade sheets, making it a more accessible DIY project. Plastering is a labor-intensive craft that requires specialized skills, pushing costs to $2 to $10 per square foot. It involves applying a wet paste over a lath framework.

Durability & Performance: Plaster is generally more durable, longer-lasting, and provides superior soundproofing. It is also a better insulator, which can help reduce energy costs. Drywall is easier to remove for future renovations.

Aesthetics: Drywall provides a smooth, uniform surface ready for paint or texture. Plaster offers a high-end, naturally textured look that can hide imperfections and is often preferred for achieving a classic or historic aesthetic.

Which is better? The choice depends on your priorities. Drywall is ideal for those prioritizing a lower upfront cost, faster installation, and DIY potential. Plaster is the better option for a higher-end project where durability, soundproofing, and a unique, premium finish are more important than the initial cost.
