"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."

"This could not have gone any smoother. Despite having to re-schedule the original, 1st quoting appointment, Darren was here the very next day. I had a quote by the end of that 2nd day/appointment, was scheduled the next day for the following Monday and the 2-person team was in and out within 90 minutes. My kids didn't even wake up(granted, they could sleep thru the emergency siren!) but wow. My attic/crawl space is now fully insulated! All this while we are adjusting to our new normal of social distancing and heightened sanitary measures. I would use AFI again and would recommend them based on this experience."

"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!"

Drywall Insulation questions, answered by experts

It is possible to apply plaster on the interior or exterior of your home, but we don’t recommend it. Plaster is easy to apply in theory, but in reality, it can be a challenging material to work with, and it’s difficult to get the finished product to look clean, even, and smooth. Many DIYers end up calling in a professional afterward to touch up the area or even redo it entirely because of mistakes they made in the process. Hiring a plaster pro will cost more, but it’s usually the best option to achieve high-quality results.

The best way to make long, straight cuts is to use a utility knife and a T-square to score the sheet, snap along the score, and then finish the cut by cutting through the paper on the opposite side with the utility knife. If you’re making small cuts, curved cuts, or cutouts for electrical boxes or light fixtures, you can use a manual jab saw to keep costs down, but an electric spiral saw or oscillating multi-tool will get the cleanest, fastest cuts possible.

Plastering and skimming are two different techniques for finishing walls. Plastering involves applying a thick layer of a plaster mixture—typically containing gypsum, lime, cement, sand, and water—to create a new surface. This process often requires multiple coats and is used for repairing significant damage or creating decorative textures. Skimming, on the other hand, is a technique that involves applying a thin layer of drywall compound or joint compound over an existing surface to smooth it out, covering minor imperfections, small cracks, or uneven textures for a polished look. Plastering is generally more costly and labor-intensive than skimming. Although some people use the terms interchangeably, they refer to different processes and materials.

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. 

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.
