"Tech who showed up to do inspection was thorough. Climbed into small attic, took pictures and explained what their findings were. Other inspections (I had 2 more) just popped their heads into the entrance and too my word for what may need to be done. Scheduling with Attic Construction was simple. They showed up on time (early). They let me peak up their as they cleaned up old insulation and remove rodent droppings (biggest concern). They finished within the day as promised and cleaned up after themselves thoroughly. Our home was well protected from dings/damages as they wrapped corners of walls, stairs etc. We have noticed improvement from having only 3.5 inches of insulation to now nearly 14-15 inches. They recommended a "combo" of batt insulation (Around the entrance) and blown in for the rest of the area. This allows you to pop in there with out blown in insulation falling all over the place. They also recommended and performed rodent proofing/sealing. We were sent photos of both before and after their work. I would highly recommend this company."

"Strongly recommend getting an energy audit completed on your home, especially when it's complimentary, thank you, Paul! There were quite a few items that needed attention in our home. The technicians Justin and Fernando were solid. They arrived on time, did a great job, were polite, and were very clean. They took before and after pictures, which shows how much I needed the work done. We went with the insulation to ensure it was at least 18 inches, the duct sealing of the junction boxes and HVAC unit, and we had to reroute the bathroom vent. We even did the optional UV-C light, which makes us feel much safer and takes a load off, especially in this current environment of being conscious of germs and all. Great technicians, great company, and solid work. Highly recommend Justin and Fernando :) The email and text reminder game is on point."

"These guys are the BEST. They treat your home as if it were theirs. Isaac found some possibly faulty electric wiring in my attic and told me about it. He did not have to do that, because it delayed their finishing their job by a day, and interrupted their next job. But he is honest in decent and wanted my home to be safe. They removed all of the old insulation, replaced my ductwork, and blew in new insulation. They were kind, courteous, and professional at all times. The other two estimates I had did not alert me to the need for new insulation, and one company never even looked in my attic. I highly recommend this company, without hesitation. They are fair, honest, And worth every penny. I feel safer now and I know I am breathing much cleaner air."

Insulation questions, answered by experts

Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated.

It depends on your needs and preferences, though many homeowners think it is worth it. Not only is blown-in insulation easy to install, but it is highly efficient with thermal regulation. Most types are mold-resistant, flame-resistant, insect-resistant, and, most importantly, completely safe.

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.

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.

The best type of insulation for your home depends on your specific needs, climate, and the area you are insulating. For new construction, structural insulated panels are a highly energy-efficient option that is easy to install during the building process. In very warm climates, reflective insulation can be a cost-effective choice. For cold climates, fiberglass is an excellent option due to its high R-value and resistance to settling over time. Spray foam works well in humid environments because of its moisture-resistant properties. For standard attics, loose-fill, spray foam, or blown-in insulation are all suitable options.
