"The staff was friendly and professional. They demonstrated a desire to get to work asap which made the selection easy. Also got a spray foam insulation bid for crawl space and we will go with SPF for this large expense. Spay foam crawl supports our heated floors so that more heat will heat people opposed to rats in the crawl..."

"Acorns Attic was hired for a rodent removal job and I had some insulation replaced since it was dirtied with rodent droppings. Phil and team did a great job. They took plenty of pictures of before and after. I haven’t had rodents since they patched up the openings and the insulation looks great!"

"They removed old hot/cold water pipe insulation that was in poor shape, and installed high quality rubber pipe insulation. Removed old support uprights that where of poor quality, and not installed correctly. Installed new high quality uprights, and attached them to the support beams. Jon and his team at Square 1 Venture Group far exceeded my expectations. From first contact till the end of the project their communication and workmanship was first rate. They gave daily updates with the progression of the work which also included pictures. They were always reliable arriving on time, and put in a full days work. Very honest to deal with showing receipts for the materials that where purchased, and also came in under the bid price. When the jobs where completed they left the worksite in excellent condition. They do high quality work for a reasonable price and do it right the first time. I would definitely hire them again."

"The workers were on time. Very efficient. They did a blower door test and found the air leaks and insulated these areas. Blew installation above the garage, cleaned out the crawl space and put new installation there and basement. Found a water leak from my toilet,Thank goodness. Covered everything in the basement and swept and cleaned up after. I would recommend them!"

Insulation questions, answered by experts

If you have blown-in insulation, using an insulation vacuum will quickly and easily suck up all the insulation. Many come with built-in HEPA filters for added safety. While some people suggest breaking up large batts and feeding them into the vacuum, this can expose you to more fiberglass fibers. With batts and rolls, carefully removing them and placing them into garbage bags is a better process.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn’t prevent ventilation, it can be as thick (or thin) as you need.

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.
