"Abraham was very prompt visiting my home to bid on my insulation project after I called him. Once I accepted his proposal, the crew was able to begin work very quickly. The three workers were very friendly upon arriving. They were hard workers both days that they were completing the project. They were very conscientious by placing covering on my floors & cleaning up after the job was finished. I would definitely recommend Insulate Iowa LLC for your project."

"I am 100% satisfied. Excellent customer service, on time, friendly and knowledgeable. I had insufficient insulation in my attic, and they remedied the situation quickly and professionally by adding enough foam insulation to achieve R-49. Also helped me with my rebate form for MidAmerican Energy. Top notch!"

"Prevailing came in to insulate my basement and attic. The workers were professional and worked the entire time they were here (which seems like a low standard, but I've had situations where 4 people come to work and 2 stand around talking for most of it from other companies). More importantly, they explained what they were doing as they did it, and cleaned up after themselves before they left! Scheduling the service was quick and easy since they were able to use our Alliant Energy quote to avoid a second home assessment, and they came in under budget. Very satisfied - plan to have them back to blow insulation in the exterior walls before winter."

"Abraham and his crew are amazing! He came highly recommended from my best friend that her home insulated. Fantastic communication, easy to work with, even when we had extra questions and concerns due to bad service people we had previously worked with. He eased our minds, he's professional and his crew was polite and cleaned up everything at the end of insulating our 3 attics!"

"Jeff Smith is based at the Waterloo office. He was very good at customer service & responded to my emails in a reasonable time given this is probably a busy time of the year (November) for them. I am having additional blow in insulation behind a knee wall & in the attic to bring me up to code. The work has not been completed yet. I am waiting for an energy audit. That is why I can only rate the company as a 3."

Drywall Insulation questions, answered by experts

It’s not a good idea to plaster over broken plaster (unless by broken you’re referring to cracked, in which case that’s perfectly fine). However, broken plaster can be a sign of a larger underlying issue like foundation damage or severe damage to the lath holding up the plaster, so it’s worth investigating before you simply plaster on top of the damage.

You can skim coat plaster, but it’s better to repair the plaster itself. A skim coat is a thin coat of drywall joint compound spread over the surface of a wall. The result is a flat finish that looks pleasing, but part of the appeal of plaster is its imperfections and aesthetic. Skim coating is best when limited to drywall applications.

For maximum stability, install grab bars on wall studs, as this will adequately support the weight. However, if you don't have access to studs, you can get by with wall anchors. If opting for the latter, choose specialty hollow wall anchors. 

On average, drywall installation costs around $2,000, with a typical range of $400 to $6,000, including materials and labor. The final price depends on several factors. The most significant is the size of the area, as many contractors charge per square foot. Other cost factors include the complexity of the job (e.g., cutting around multiple windows and doors, corners, or curved walls), accessibility, location, the thickness of the drywall, the height of the room, and the desired level of finish. The level of finish can range from simply hanging the drywall to taping and mudding the seams and painting the walls.

You can usually tell if you have plaster or drywall by touch (plaster is harder, colder, and smoother than drywall) or by tapping on it (drywall sounds hollow, plaster does not). If you still cannot tell, peek under an outlet cover and check the cut edges. The rough edges show the composition of the wall. You will see either drywall (two paper sheets sandwiching gypsum material) or only plaster material (no paper sheets).
