"Perfect wall LLC service was amazing! They went over the job with me and explained everything and taught me a thing or 2 about insulation. After the job I went to look at the results and it was exactly how he explained it! They use measuring templates you can see the actual depth of the insulation in all parts of the attic which was awesome. The vent out the exterior wall was so perfect I couldn?t even find it unless I really looked. Everything came out perfect they took the time to clean up very well also which my wife was very happy about! 10/10 would use again."

"A soft wall due to improperly installed gutter by some other entity or homeowner caused water to constantly leak into the wall from the exterior roofline. This soft wall grow moldy and become riddled with pests/bugs. The contractor identified the potential issues, agreed to explore and open the walls and discuss the conditions, made sound recommendations for repair and did exactly what was noted in the repair (replaced a load bearing exterior wall, fixed the sill plate, completed the roof, shingles etc. and closed up the walls on the inside with insulation and sheet rock.). The work was timely, well done, the workers were clean as they did the job and kept the rest of the property clean. The manager of the job David Apel was and is an excellent communicator with phone/email/text and photos of processes and progress. I am going to use this company in my own investment endeavors on other properties and projects given the level of finished work, the timing and especially the level of detailed communication."

"Recently had my attic insulated by Best Homes. Chris and his crew were professional and very efficient with their work. They insulated my attic within a few hours and left my house cleaner than it was before they got there. I wouldn't want the job done by anyone else."

"Highly professional and extremely accommodating. There were bats in my attic when they went in to redo the insulation. They calmly (as they could) told me the situation and came back at a later time with no added cost. Did an excellent job, and had a incredible attitude throughout. Cannot recommend enough. Thank you!"

"I liked that the first questions we were asked was "Have you had a home energy audit done? Did you know you can get a rebate on your insulation project?" Before even knowing the scope of our project, they were looking to help make it more affordable for us."

"We hired Connecticut Basement Systems to encapsulate our 23 year-old crawlspace.  The sales representative came to do an estimate and was very helpful - he explained his recommendations clearly and gave us literature which explained the science in more detail.  We were somewhat cost-conscious and he helped us get the most bang for our buck.  We were able to arrange financing from an affiliate, and the process was incredibly easy.
The crew came to do the work yesterday - they laid down a drainage mat and rigid insulation on the floor slab and walls topped by a plastic liner, set up a dehumidifier with a drainage line to a sump pump (which they also installed).  I was amazed that they were able to complete everything in one day.  When the job was complete, the foreman went into the crawlspace with me and showed me everything they had done.  I had spent some time in the crawlspace removing the old insulation and was struck by how clean the finished product felt - to say nothing of the energy efficiency and moisture removal benefits.
We have no plans to do additional work in our basement for the time being, but if and when we decide to do any, Connecticut Basement Systems will be our first call.  Truly a pleasure to work with from start to finish.

Drywall Insulation FAQs, answered by experts

Most drywall used for interior walls of homes is 1/2-inch thick. This size strikes a balance of being easy to handle and hang while being thick enough for the durability needed on interior wall applications.

Applying spackle is a simple DIY project that most people can complete in just a few hours. Even homeowners who have little DIY experience can complete this project in an afternoon. However, if you're uncomfortable with the project or don't have the time, you can always hire a pro to help.

With its breathability and flexibility, lime plaster is among the most durable of all plaster types. It's also fire-resistant and has a proven track record, as people have been using it for thousands of years.

However, all plaster types will last for many years with the right care and treatment. Proper preparation and installation will also help ensure your plaster walls look great for as long as possible.

If you're comfortable hanging drywall yourself, you may be comfortable finishing it. But it's worth noting that finishing drywall adds several steps to the process and a lot of waiting time. Hiring a drywall installer may be the way to go if you'd rather spend your time doing other things or are nervous about leaving a rough surface.

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.
