"Nick and his crew were so informative and pleasant to do business with. We had attics insulated, new vents installed, and outside blown-in cellulose, and they worked long hours to make sure everything was done correctly. I would definitely recommend this business. A great surprise was how the insulation muffled loud outside noises (fireworks and loud vehicles)."

"They did a good job. They ran the vacuum after they were done, they laid down guards to make sure none of the insulation got anywhere else in my home and wore hospital booties so they didn't track anything in. They helped me take down my drapes and made sure that they had guards in the attic so the insulation wouldn't cover the ducts. I was greatly pleased with their work and I can already tell a difference in the temperature in my home."

"It was a small job. They sealed the vents to the crawlspace, then, since there was already solid insulation panels on the walls, put a vapor/moisture barrier, in the form of a tarp, 4 feet wide and as long needed, completely around the crawlspace. It was then sealed to the walls with "nails" and adhesive. This seals the wood frame of the house from the 'Outside", the ground, which is the floor of the crawlspace. A 20 mil thick, quite heavy, "floor" was installed, also in the form of a tarp, It went up the walls about 3 feet and was taped to the 'tarp" on the walls, using a tape made for this application. The piers were wrapped with the same stuff and taped to seal the inside from the outside. the "floor" is also a vapor/moisture barrier, but, heavy enough to walk on if needed. This basically makes the crawlspace another room, rather than the outside. Our house is one year old and was already getting mold on the floor joists. Since the air in the crawlspace will now be heated in the winter and cooled in the summer, just like the rest of the house, the mold and cold (52 degrees) floors we experienced last winter will hopefully be eliminated. We shall see when dumb winter gets here."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"

It went great, they came out on the day that we were told. During the removal of the layers of the roof all waste material were placed in there trash dumpster and any material that was on the ground was picked up. They even ran a magnet  over the yard to pick up any nails that might have fell in the grass. During our discussion of the roof before placement Eric suggested that we needed to add a few more box vents to insure that we had proper ventilation on our roof. Both me and my wife were impressed on the look of the finished project and we would hire Maximus General Contracting again.  All waste material were picked up and the drive way was clean and free from trash.

Insulation FAQs, answered by experts

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.

The cost of installing spray foam insulation is $2,760 on average, but this cost can be as low as $650 or as high as $7,700. The main cost factor is the size of the insulated area and the type of spray foam insulation. 

Polyurethane spray foam costs between $0.44 and $1.50 per board foot, where a board foot is equal to the volume of a one-foot length of a board. More expensive options, like soybean or vegetable oil spray foam, range from $1.50 to $3.00 per board foot.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

Buying a house with vermiculite insulation is not recommended without going through a proper testing process. Vermiculite insulation can potentially contain asbestos, which poses health risks when disturbed. While it is possible to purchase a home with vermiculite insulation, you should have it tested for asbestos, and ensure proper containment if asbestos is present. If asbestos is present, you will want to hire a professional to remove it, ideally before you move in.
