"Javier who owns Dixie Insulation was very professional, and went out of his way to make me happy. I must admit, I'm very picky, but Javier's crue were punctual, and did a first class job. I had my old insulation taken away, and I went with the hard foam. There was hardly any smell, which I read, was because, it was properly mixed. I had one, or two small issues, in which Javier took care of them immediately. I highly recommend Dixie Insulation!"

"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

Drywall Insulation questions, answered by experts

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.

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.

The time it takes for thinset to dry is determined by your room’s ambient temperature and humidity levels. Assuming the average humidity level is around 40% with an average temperature of 70 degrees Fahrenheit, thinset can dry within 48 hours. Lower temperatures and higher humidity can extend the curing process beyond 72 hours, while high heat and zero humidity can shorten the curing process. However, thinset can crack if it dries too fast.

If your home was built before the 1940s and was not remodeled in the past 50 or so years, you probably have plaster walls. Aside from assuming, there are some practical ways to tell if you have plaster walls, including the following: If you knock on the wall and it feels solid, not hollow, if you can’t insert a thumbtack easily, if there are cracks that look like spiderwebs, or if your home has curved, arched, or swirled walls, doorways, or window openings.

If you have an unfinished basement or attic, you could examine the backs of any finished walls to check, too.

Yes, drywall nail pops are a common occurrence in homes, both new and old, resulting from the settling and shifting of the structure over time. Though not present in every room or on every wall, encountering nail pops in different sections of a home is not unusual, particularly if the temperature, humidity, or foundation has experienced changes.
