"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)."

"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."

"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

"

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

Reduces energy costs, improves comfort, and prevents ice dams in winter.

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

While freezing pipes are less of a concern in warmer climates, pipe insulation can still be beneficial because it helps prevent condensation on cold water pipes, reducing the risk of moisture-related issues like mold growth. It also helps maintain water temperature, reducing the energy needed to heat and cool the water, which can ultimately lower your utility bills.

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.

If you feel your energy bills are too high or your HVAC system is working harder than necessary to maintain the correct temperature in your home, you may have an under-insulated home. If you’re unsure, consider having your system’s efficiency assessed by a local independent energy auditor.
