"I can’t say enough nice things about Jersey State Insulation. Sebastian and his crew are absolutely amazing. They work very hard and are very conscientious of your home. When they did the insulation on my home they were very careful when moving things around and cleaning up after the job was done. Sebastian is very friendly and made every effort to explain everything and make sure I was happy with the work being done. I met with other insulation companies, but none seemed nearly as competent as Jersey State. The others wanted to charge me a lot more for something I didnt think I needed. The others though my problem was only the attic. Sebastian inspected the attic and said there was nothing it needed. Other contractors didn’t even want to attempt blow-in insulation, but Sebastian and his crew did it and the result is fantastic"

"Can I give them a 10 for value for the money? Dave, the owner, was great. Unbeatable price and they did a great job. I'm actually shocked by what a difference it makes. My house had no insulation in the walls and the furnace ran constantly. Now when I touch the walls, instead of being ice cold, they are room temperature, and the furnace barely runs."

"I have only glowing things to say about our experience using Home Genius Exteriors. From the thorough initial estimate and comprehensive inspection of the worksite and what the job would entail to the final bit of blown-in insulation, our multi-team project was completed to our satisfaction in a timely and professional manner. In the course of four days, we had a new roof, new trim, new gutters, and new insulation. Each part of the project required a different team. Each crew finished their task within the projected timeframe. Home Genius coordinated everything, including ordering and delivering the materials and arranging for the delivery and removal of the dumpster. Thanks to our Project Coordinator Ivan, every step in the process went smoothly. He arranged for workers to be at our home on consecutive days: we did not have any time in between steps waiting for availability of the next team. Ivan kept us informed of progress at every step of the way."

Drywall Insulation FAQs, answered by experts

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.

Drywall mudding can be done in one day if the project is small and the desired effect isn’t too complex. If you need multiple layers of mud, one day may not be realistic. But a single room that requires little more than joint compound on the seams and screws can be done in a day or two.

Costs depend on damage size, labor rates, and whether additional services like painting are required.

Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.

Certain drywall textures, like sand and sometimes popcorn, can be smoothed by applying skim coats, sanding the walls, or chipping away the texture. However, it’s worth considering removing the texture and starting with a blank canvas. Smoothing textured walls requires a lot of sandpaper and elbow grease and can take longer than just outright removing the texture.
