"Claudio and his team did the blown insulation in my attic today and they did an AMAZING JOB; I am very happy with their work. He is very professional and answered all my questions from start to finish, he arrived at the time he said he would and cleaned up to a point that you would not even know they were here. :) I would most certainly refer them I would give 10 stars if I could. I got two other estimates, and his price was by far the best!"

"Not only does the roof look gorgeous it's efficient and quiet! It reduced our electric bill along with being cooler, it much quieter. We went with the insulated metal roofing system, which we would recommend, it takes a bit longer and it's more costly but worth the time and money. Frank and his team are friendly, straight forward, and easy to work with. They were efficient and clean, our neighbors even commented how much they appreciated how well they cleaned up each day to keep our road and driveway clear. We would highly recommend them for any roofing job!"

"We met with 3 different companies to advise on getting solar panels. The first 2 companies basically just told us what size system we could get based on state and federal tax rebate levels. Heard an advertisement for Sunpro on radio and decided to call them; turned out to be a good decision. Kara with Sunpro was extremely informative and had a nice package put together for us to review. She even researched our home and had an idea of how much production we could expect with the recommended solar panels. Even after selecting Sunpro, I called Kara with questions about things I'd heard from others or something I forgot to ask. I never felt like I was a burden and she always returned my calls if I had to leave a message. The complete team with Sunoro were professional and eager to help. Satisfied with new solar system and looking forward to enjoying savings on electric bills.

"I was having issues with mice in my attic after hearing them for 2 weeks I had enough I called CritterX an their response was amazing, they removed all my contaminated insulation replaced it with new insulation an set traps up. They don’t use no poison and that was a plus for me right away, it only took them a days work an now I’m mice free they also come an check my traps every week just to be on the safe side an on call when ever I need them, I recommend CritterX any day of the week also for the price I couldn’t give up the opportunity ! I’ll be telling friends an family who to go to for their critter problems for sure."

Drywall Insulation FAQs, answered by experts

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.

There are several benefits to wet-sanding drywall, but the main perk is that it produces far less dust than dry-sanding. As a result, wet-sanding poses fewer health risks and makes less of a mess in your home. Plus, damp sponges are less abrasive than sandpaper, so there’s a smaller chance of scratching or damaging the drywall paper. Wet-sanding also creates a smoother finish than dry-sanding.

It’s highly recommended to use studs for a TV mount. The last thing you want is to be watching your favorite show when the TV falls off the wall. Studs are much stronger than drywall and quite a bit stronger than drywall anchors but, if you can’t find the studs or there simply aren’t any where you need them, you can use drywall anchors. It’s extremely important to make sure the anchors are rated for the load of the TV. We recommend using anchors that are rated far beyond the weight of whatever you’re hanging. Our suggestion is metal drywall toggle anchors. 

The two most common drywall thicknesses for ceilings are 1/2-inch and 5/8-inch. For most standard residential applications, 1/2-inch drywall is sufficient and widely used. It provides adequate support and is lighter and easier to handle during installation compared to thicker sheets. However, 5/8-inch drywall is often used for specific cases where additional benefits are needed. It is heavier but provides superior sound dampening and fire resistance. You should consider using 5/8-inch drywall for ceilings in commercial buildings, between a garage and a living space, or above a finished basement to meet building codes or for enhanced soundproofing.

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.
