"Cny insulation came to my facility and our attic had very little insulation. They put blown in insulation, cellulose, along with fixing a bathroom vent, and a ventilation pipe. The before and after pictures showed over 15" of cellulose. They left the premises (church) immaculate. I would recommend to anyone. What a great job!"

"Bob contacted us to enquire if they could begin the work a few days earlier than scheduled. We consented to that and they began work ahead of schedule. The crew was three men, Bob, Ryan and Ryan. They were courteous and respectful and efficient. I have a background in construction trades so I know good mechanics when I see them. These men were pros and did a quality installation. I am very satisfied with the job they did and our home is far more comfortable since they finished. I know that our furnace runs significantly less and I expect our energy costs will be less. I emphatically recommend Superior Insulation and especially Bob and the crew. You will not be disappointed."

"There were two crews working at the same time.  The insulation crew headed by Jim worked outside for three days in the extreme heat, the 2nd day hitting a temp of 101.  They insulated  inside and out and you would never know they were here.  They cleaned up every last scrap and vacuumed all the residue.  They were efficient, professional and  personable to work with.    The HVAC crew, Mike and Frank had to remove my cast iron furnace that the previous owners had set in cement; (the guys said it looked like the furnace was put in and the house was built around it!)  It was quite a job getting that out of my basement but, they did it!. They were also very professional, friendly and answered all my questions with courtesey and information I could understand.  They even programmed my thermostat and explained how I could change it if needed.    I now have a high efficiency heating and air con system that should decrease my energy bills to a third of what I was paying and I won't have to freeze this winter.    I would highly recommend Green Homes and will call on them again when I am ready to replace my old windows."

Drywall Insulation FAQs, answered by experts

Yes, small, superficial cracks are normal as homes settle. Older homes have a higher chance of showing signs of settling through hairline cracks from temperature changes, moisture changes, and soil shifting. However, larger cracks, or discolored cracks from water damage, may signify a bigger problem that requires reparations and preventative measures.

Plaster walls typically last between 30 and 70 years, but depending on the quality of the materials and the moisture levels in the building, they can last for over 100 years. With expert application and consistent maintenance, plaster can even last for centuries. To extend its lifespan, it is important to have the plaster professionally installed, address any water damage promptly, and repair small cracks as they appear. Regular inspections by a professional can help identify and address concerning cracks before they become significant issues.

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.

A post-drywall inspection could uncover many problems that weren’t present during the pre-drywall inspection, including insufficient insulation, missing weather stripping, improperly installed plumbing and lighting fixtures, flooring damage, drywall damage, plumbing leaks, aesthetic issues, and more. Structural problems, which are often expensive to fix and are common reasons to walk away after a home inspection, are easier to see before the drywall goes up, but a post-drywall inspection may highlight minor issues with house settling and foundation problems.

Plaster is a beautiful finish but is labor-intensive to install and remove. It’s vulnerable to cracking and more sensitive to moisture variance than drywall. Installing plaster on a new wall is an expensive process that can take days to weeks, depending on the scope. Removing a plaster wall can also be quite expensive and time-consuming.
