"The owner of the company Jason Taylor spent time in my attic before we contracted with them so he could give me good and correct information. He also participated in the work of shooting in the insulation. He was very hands-on. Donâ t usually expect this attention from the owner/boss Was very pleased."

"Did a great job...it was a very long day from start to finish however. They did a great job of keeping everything as clean as they could since our attic access was in the master closet! Yikes! Really made a difference and our house stayed much cooler with the fan and new insulation!"

"Rafael and his company are great people to work with. Their in-depth estimate and assessment of the attic is unparalleled, not to mention competitive. They were very flexible with accommodating our needs on our schedule. Very responsive Manager too, would reply to my calls and text almost immediately. I really appreciate how hard working and efficient these guys are. I had other workers doing work on our house at the same time and they were also impressed at how clean they left the attic before installing the new insulation. Rafael values your business and his work and attitude definitely demonstrate it. Call them you won't regret it."

Drywall Insulation FAQs, answered by experts

You can put drywall mud over paint to even out the surface or entirely resurface it. Sand the surface with 280-grit sandpaper, vacuum the debris and dust with a shop vac, and clean it with a slightly damp cloth. Allow the surface to dry. Apply drywall primer, especially if you’re skim-coating an entire wall. Apply the right type of drywall mud over the surface and smooth it with a trowel. Allow the layer to cure fully, then sand it before applying another layer or painting it.

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.

Regularly in areas prone to moisture or high traffic to catch issues early.

The cost to skim coat drywall is $1.15 to $1.35 per square foot. Most of the cost is labor, for the necessary skills to apply the skim coat with precision using high-quality tools. This is a job better left to the professionals for the best outcomes.

While every home has its own unique needs, ceiling drywall installation typically follows a staggered or stepped pattern to enhance structural integrity and reduce the visibility of seams. Starting from one corner, sheets are placed perpendicular to the ceiling joists, with the ends of adjacent sheets meeting along the center of the joist. The next row begins with a half sheet, ensuring joints don't align vertically. This alternating pattern, combined with proper taping and mudding, creates a seamless appearance and strengthens the ceiling structure, minimizing the risk of cracks over time.
