"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."

"On initial inspection, they discovered that our old heat registers were the kind with asbestos (house built in the 60's), so they had to sub out the abatement part of the job. Once abatement was complete, the workers showed up each day at the time they said they would arrive. They were all friendly and professional. They kept everything clean. The took pictures in the attic to show me before, during, and after the work. They explained what they were doing and showed me the new ducting they were installing (quiet ducts) and explained the more "up-to-date" way of putting in the duct work than what we had. After the work was complete, we noted that the furnace ran much quieter (due to new ducting), and it ran WAY less often. The house stayed much warmer while running the furnace much less often. Best of all, our gas bill dropped! Now that we're moving into summer, the house seems to be staying cooler on these warm days. We don't have A/C so we're hoping the new insulation will keep the house cooler as the days continue to warm up. Very happy with the company and all the work they did. I would recommend them!"

"The crew was on time, worked hard and efficiently, and cleaned up the work site beautifully after they were done. The subsequent patching, stucco replacement, and painting were so superb one would never know the entirety of the house had been drilled into in dozens of places. As for the insulation product itself, I was able to feel the positive effects of the insulation almost immediately. Happy to recommend Guardian for wall insulation work."

Drywall Insulation questions, answered by experts

Regular dusting, occasional repainting, and avoiding harsh scrubbing preserve the finish.

Yes, any parts of drywall that are wet or overly moist will need to be replaced. Drywall is intended to be dry (it’s in the name, after all.), as excess moisture can lead to mold and mildew and eventually corrode your home’s foundational building pieces. Do regular inspections in your home to make sure all your plumbing is intact and in good condition—this will go a long way toward preventing leaks.

Yes, you can install drywall over plaster, but there are important factors to consider. While it can create a smooth, flat surface, it is often not the best approach. Installing drywall over plaster will increase the wall's thickness, which can cause issues with existing window and door frames that may no longer fit. You might also need to adjust power outlets to keep them accessible. A better, though more expensive, option is to remove the old plaster and lath entirely before installing new drywall. Drywalling directly over plaster seals in the old material, and if any problems arise later, you will need to remove both layers down to the structural beams for repairs. Given the potential complications, this job is best handled by professionals.

Technically speaking, you can use drywall primer over plasters. However, oil-based primers work the most effectively on wall plasters. Meanwhile, water-based primers work just as well with drywalls. Nowadays, there are also universal primers suitable for drywall and plaster. Overall, you will be fine as long as you are using a trustworthy brand.

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