"I got several estimates from several providers. The pricing seemed just ok with those other providers but something seemed off. Good Life came in and made sure that I was getting the correct amount of insulation (where the other service providers had under estimated) and helped me to get into a loan through the utility company for the cost of the insulation. Good life is a qualifying contractor for this and it saved me a lot of out of pocket expense. They came in and did what they had to do. They were professional and made sure the work was done well."

"The crew worked quickly and efficiently to replace and upgrade the fiberglass batts in our basement and crawl space. I’m pleased with the outcome. (I put in even more wire supports afterwards — to secure the insulation between the joists — but that’s just my OCD.) It was a relatively small job for this company and I thought the cost was fair."

"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."

"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."

Drywall Insulation FAQs, answered by experts

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.

All plaster walls will crack over time due to normal house settling and expansion and contraction from temperature and moisture changes. Small, thin hairline cracks are generally not serious and are mostly a cosmetic issue. However, larger or more significant cracks can indicate structural problems.

Here's how to tell the difference:

  • Cosmetic Cracks: Cracks that are 0.5 cm (0.2 inches) or thinner are typically cosmetic.

  • Structural Cracks: Cracks wider than 0.5 cm, excessive or deep cracks, multiple cracks in the same area, or cracks that span around corners can signify a structural or foundation issue. Cracks along the joints where walls meet the ceiling also warrant attention.

For cracks wider than 0.5 cm, structural repair is needed. If a crack is 2.5 cm (1 inch) or wider, or if you notice any signs of a structural problem, it is best to contact a plaster repair professional to assess the damage.

Glass walls are more expensive overall than their brick or drywall counterparts. However, if you need walls for a building with more than two or three stories, glass walls are the more budget-friendly option.

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.

The best tool for skim coating drywall is a skim coating blade, which can smooth out joint compound in wide stretches. While you could use a smaller drywall knife for skim coating, the smaller size means it’ll take longer to smooth out each section. Instead, consider investing in a skim coating blade for the quickest application.
