"Prodent Homes did an excellent job with our attic remediation. They removed the old insulation, sanitized and re-insulated the entire attic. The owner David was easy to communicate. The crew lead Jose was very experienced and communicated well. The job was done professionally. We are happy with the results and will use them again if we have another insulation job."

"The crew that originally came out were very efficient and friendly. They finished almost everything in the time that was stated. The only thing with them that I was concerned with was that they keep asking me what they were supposed to be doing. They knew that they were supposed to doing insulation but didn't have the details. And when i told them that I would have to go back to my paperwork they said that they would call the project manager. On the 3rd day they needed to do one last thing to an outer wall but couldn't do it because it was too cold and they were concerned that if they tried to remove the siding it would crack. They left on a Wednesday telling me that someone would contact me to come back on Saturday to finish the job. Fast forward to Friday, I get a few missed calls and then text messages saying that they had a crew in the area that wanted to come by in 30 mins. I wasn't home but finished up what I was doing to meet them at my house. When they get there they don't even know what the job is that they are supposed to be doing and don't have a ladder tall enough to reach the area. So they decided that they could do the job from the inside and said that they would need to drill a couple holes in my closets to fill the wall with insulation. They were very admit that that the holes would be repaired and the drywall fixed and painted and that someone in the company would call me and a crew would come out to do the drywall repair. So they do their part and leave. After they leave I realize that they put 6 holes in my wall. Not what i was expected but they did a decent job on plugging the hole back up with the piece of drywall that they removed. I waited for someone to call me about fixing the drywall but they didn't call. So after a week of waiting I called the company to ask about it and the mold remediation issue I was having (more on that in a sec). They seemed unaware on the drywall needing to be fixed and said they would send someone out to look at both things. A few days later someone comes out. They were unaware of the drywall repair but were there to look at the mold issue. Now about the mold issue. I will get back to the drywall in a min. So I paid for them to spray something on a strip of mold that we had in our basement and was told that after it has been sprayed that it would like nothing was ever there. Well after them spraying it twice it still looked awful. The wood looked but as black as before they came. So when these guys came to look at it they said that there was definitely no mold there. the problem was with my wood. So much for it looking like nothing was there. Now i have to hire someone else to sandblast it or something. So after these guys looked at the basement they said that they would look at the drywall. They look at it and are like "oh, i don't think we have the materials on our truck to fix this but I will take a look". They did have the materials and would tape it and mud it but weren't really experienced in drywall repairs but they knew enough to do the job. I should have stopped them right there but I thought it would be okay. Well once the mud dried I could tell what an awful job they had done. I will have to either try to fix it myself or hire someone to do it. And I probably should have called them back again but I am really tired of them sending me people that don't know what the job is before they get to my house and are not prepared. Only getting a C because the first crew was decent."

"The company did a good job replacing old insulation in our attic. There was a communication hick-up but the project manager we worked with - Jamie - was able to correct and resolve the issue."

"After my call to Discount Energy Services, I knew who was coming and when to evaluate my attic insulation. The estimate was prepared on-site with pricing. The workers arrived and knew exactly what they were to accomplish, which they confirmed with me. They prepared the entire path with clean drop cloths and created a plastic drape around my attic stairs. The foreman was glad to explain any aspect of the procedure. My attic was upgraded to R-49 and the difference is notable."

"They wanted to inject very expensive sealant into the ducts to seal the seams. The company I hired used insulating tape over the seams instead, for a greatly reduced price. The total price difference in their proposal and the company that I hired was about $4500."

Drywall Insulation questions, answered by experts

Yes, if there is mold in your drywall mud and you then use it to build walls in your house—or if mold develops in your set drywall, like it can in hot and humid areas—it can lead to illness. Mold in your drywall (or other parts of your home) can make existing respiratory conditions or allergies worse, and the effect can be more intense for those who have existing health issues or compromised immune systems.

Wet-sanding and dry-sanding each have pros and cons. Dry-sanding is less messy, so it’s a good option if you’re trying to minimize dust (for example, if you’re sanding an occupied home or working with particularly dry or dusty drywall mud). However, dry-sanding is quicker because you don’t have to keep rinsing a sponge or wait for it to dry before painting.

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).

A jigsaw is commonly used to cut holes in drywall. It offers versatility and precision, making it suitable for creating circular or irregular openings. When equipped with the right blade, a jigsaw can swiftly and cleanly cut through drywall, making it a good choice for DIY projects.
