"I thought I had contracted to have about 1/4 of crawspace completely replaced with new insulation. However they replaced part of it and tacked up the rest that was sagging. Maybe my fault that he did not understand I wanted that section completely torn out and for him to replace that section. They did do an excellent job. They also added blown in the attic and added some batt insulation to naked walls in garage. I would recommend them."

"My family and I have been living in an RV for over a year now, due to hurricane Florence. It has been a nightmare dealing with shady, lazy and difficult tradesmen but doing business with Mitch has been the easiest thing in this whole process. I called him on a Friday to insulate my entire home and he was completely done by the following Tuesday, before lunch time. He s extremely friendly and an excellent communicator. He kept me in the loop the entire time and showed up when he said he was going to. He does quick work but he is very proficient and he actually cleaned up after himself, which seems to be completely unheard of. We called around to multiple businesses for spray insulation and Mitch is by far the BEST price you will find out there. He even gave me a really good discount because I think he s just a nice guy. I highly recommend Mitch. He will make your life easier in regards to upgrading your home."

"From start to finish - the scheduling process, quoting and to completing the job - everything was handled smoothly, with utmost friendliness and professionalism. On the day the work was to be done, I received updates for estimated arrival, and when they finished they cleaned up as if they were never there. I highly recommend Koala Insulation and I will be using them again for my next project."

"Hutch is a good businessman! When he learned they were short one guy to finish installing the insulation after they had taken the old insulation out, he did not want to leave us without insulation with the heat we had been having. Hutch came down himself that day to make sure the job was done."

Drywall Insulation FAQs, answered by experts

Pros ensure smooth finishes and lasting repairs, avoiding visible patches.

Yes, professionals often repair minor wall openings made for insulation injection to restore the surface.

If the holes in the plaster are small, you can fill them with layers of patching plaster until they’re filled. After it dries, you can sand the plaster and paint over it. If the hole is much larger, consider using bonding plaster first and then a layer of patching plaster, completing the process with sanding and a layer of paint.

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly. 

When you are learning how to tape and mud drywall, waiting for things to dry requires a lot of patience. So how long does drywall mud take to dry? On average, it takes about 24 hours. However, it depends on things like the thickness of the mud, as well as the room’s temperature, humidity, and ventilation. Using thin layers of mud in a warm, low-humidity room with good airflow reduces average drying time. You also could speed up drying time by making use of hot drywall mud, which consists of a powder that you mix with water, instead of using pre-mixed mud.
