"Comfenergy was very professional thorough from the in-person estimate thru installation. Even though we didnt have a full energy audit, they still go over your entire home and tell you what should and what needs to be done. Some of the little things we did ourselves, or had our handyman. Then Comfenergy did the big part, seal and insulate the attic. We still had late 80's insulation and never a sealing done. It ended up being over an 8 hour project. They were not the cheapest estimate, but definitely the most in-depth review and recommendations provided. The two man team that did the actual work were very professional, showed us the work as the progressed, and good clean up job after all was done."

"Mark rearranged his schedule so that he could priorize our house following the completion of a process called soda blasting that is used for mold remediation. As a result ,he was able to clean the ducts immediately following the completion of the process which is important to prevent the further spreading of the cleaning product into other areas of the house."

"Bill Hawk is easy to communicate with.  I left a lock-box on the back door, they came out, and did the work while I was at work.  They coordinated with Geller Labs to have them come out and perform a final air test for me.  They did a great job cleaning up.

"Everything was outstanding--price, communication, punctuality, work quality, professionalism, cleanup, his personality, etc. Travis Graham was always on site and did much of the work himself. He had previously planted trees for us and fixed attic retractable stairs. He was always cheerful and enthusiastic despite performing grueling labor in hot humid weather.

Drywall Insulation FAQs, answered by experts

Yes, you can install drywall over plaster, but there are important factors to consider. While it can create a smooth, flat surface, it is often not the best approach. Installing drywall over plaster will increase the wall's thickness, which can cause issues with existing window and door frames that may no longer fit. You might also need to adjust power outlets to keep them accessible. A better, though more expensive, option is to remove the old plaster and lath entirely before installing new drywall. Drywalling directly over plaster seals in the old material, and if any problems arise later, you will need to remove both layers down to the structural beams for repairs. Given the potential complications, this job is best handled by professionals.

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.

The cost to install drywall is between $1.50 and $3 per square foot, while shiplap installation costs between $2 and $7 on average. In most applications, shiplap installations cost more than that of putting in drywall. However, several ways exist to reduce shiplap prices, especially for small locations or accent walls, which can keep the total cost of shiplap competitive with that of drywall.

There are six levels of drywall finish, from 0 to 5, that refer to the amount of work performed during the finishing process.

Level 0: Drywall is hung with no finishing work.

Level 1: Tape is placed over the seams between drywall sheets.

Level 2: A thin layer of mud is applied over the tape and screw holes. This level is common for utility rooms or walls that will be covered.

Level 3: A full coat of mud covers the screw holes and tape, but the surface is not sanded. This is often used in garages.

Level 4: This is the most common finish for visible interior walls. It involves applying two coats of mud over seams and screw holes, with sanding between each coat, creating a smooth surface ready for flat paint.

Level 5: This is a high-end finish for luxury homes. It includes full taping, mudding, and sanding, plus a final skim coat over the entire surface before painting.

If you plan on heating your garage, you must install a vapor barrier when drywalling the garage. A vapor barrier protects your garage from frost and mold that can occur through condensation. If your garage is unheated, you don't need to install a vapor barrier. The only exception is if you regularly crank the heat in your car before getting in it. In this case, you may still want to install a vapor barrier, as your car can heat your garage.
