"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

Spray foam is a highly effective insulative material that can dramatically reduce your energy bills and create a more comfortable living space. It does have a couple of drawbacks, however. First and foremost, spray foam insulation is much more expensive than fiberglass batt insulation. In addition, spray foam insulation is a dangerous chemical material; this is a project that is best left to pros for proper and safe installation.

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem. 

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.

Carriage, sliding, folding, and trackless pivot doors all replace a standard roll-up door. Glass doors and roll-up screens work well when you convert the garage into living space. Match the style to your driveway clearance and climate.
