"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."

"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!"

"Rightway Waterproofing is the company you want to come and waterproof your basement. I had initially set up a job looking for pros through Angie's List. I was contacted by Rightway Waterproofing via phone and email but did not respond as life happens. Well it rained really heavy again in August and I had more water in the basement. I reached out to them on a Friday and Albert contacted me immediately. They were able to come out on Monday to look at my property. Jake was thorough and friendly. He let me know what he thought we needed, explained everything thoroughly and gave us a quote which was completely reasonable. We accepted the bid and work was to commence on Thurs as they had an opening. Work was completed in one day. The area was kept pristine and they did an amazing job. The crew was courteous to my family. I could not recommend them more. I hope to have them out again at some point to finish my basement area as well. Try to keep in mind that during the season of covid many families are looking for ways to make more space in their homes or to have to home projects done. If you are waiting for work to be done just know that it is worth it! Thanks Rightway!!!"

Drywall Insulation FAQs, answered by experts

All plaster walls will crack over time due to normal house settling and expansion and contraction from temperature and moisture changes. Small, thin hairline cracks are generally not serious and are mostly a cosmetic issue. However, larger or more significant cracks can indicate structural problems.

Here's how to tell the difference:

  • Cosmetic Cracks: Cracks that are 0.5 cm (0.2 inches) or thinner are typically cosmetic.

  • Structural Cracks: Cracks wider than 0.5 cm, excessive or deep cracks, multiple cracks in the same area, or cracks that span around corners can signify a structural or foundation issue. Cracks along the joints where walls meet the ceiling also warrant attention.

For cracks wider than 0.5 cm, structural repair is needed. If a crack is 2.5 cm (1 inch) or wider, or if you notice any signs of a structural problem, it is best to contact a plaster repair professional to assess the damage.

A common cause of separation between a wall and the ceiling is truss lift—this can happen to the ceiling of rooms directly under the attic when the seasons change and wood building materials dry out, shrink, and shift. Roof trusses often dry out at different speeds, and if the bottom pieces dry out faster than the top pieces, they can shrink and pull the attached drywall away from ceilings and walls, causing cracks. Fortunately, truss lift is only a cosmetic problem, not a structural problem, and you can fix it by separating the ceiling drywall from the roof trusses, and patching the cracks.

Drywall anchors won’t work on plaster. Instead, they will more than likely cause more damage and pull out the plaster. The best type of anchors to use on plaster walls are the ones that will bite into the surrounding area, such as molly bolts and toggle bolts. Masonry anchors with expanders on the sides also work for lighter pictures.

While certain types of textured walls can seem dated (looking at you, popcorn), textured walls are a common sight in both older and more modern homes. The main reason textured walls may be here to stay is that they are an excellent way to hide minor imperfections on a wall and give it a finished appearance. Some homeowners think a coat of paint on drywall is a bit industrial-looking. However, that look works perfectly in modern home design. 

There shouldn’t be any gaps between your walls and ceiling. These can be fixed with joint compound but that is only a fix, and it’s much better if your drywall fits correctly in the first place. Sometimes gaps can appear if your foundation shifts significantly but if this is the case, you have a much bigger problem than patching drywall.
