    "I highly recommend Greenshield for their professionalism and the comprehensive service they perform. Greenshield's owner Ahmad and employees understand the advanced principles of insulation for energy efficiency: detailed air sealing of attic floors and crawl spaces, installing baffles, and sealing "top hats" over recessed lighting and in-ceiling speakers, as well as installing insulation. (I was one of those homeowners who thought that all I needed to do was "add more insulation.") At my home they removed all old attic insulation, sealed (as above), installed baffles, and installed R-44 blown-in cellulose insulation. Parker and Dave worked for two days--they were totally competent and a pleasure to have around."

    "We hired them to replace our Air Ducts and add Air Blown Insulation. We re very happy with the outcome!. They re very reasonable. In summer the house never cooled off under 86 and the a/c never shut off. Our PG&E bills were $600-$800 during summer months and we paid on it all year. The Air Ducts required a lot more work than originally anticipated ( was originally built with several different sizes when it shouldn t have been plus an add on room. They showed us the old stuff they took out and there were holes throughout so most of the cold air was going into attic not house!) They paid special attention to the back part of the house that always is hotter than the rest of the house. Even putting extra thick insulation in that room. I spent the first 3days saying It s set to 74 and it s 74 in the house! It shut off! Highly recommend them if you need work done!"

    Insulation

    "Outstanding Service from Attic Pros I recently enlisted Attic Pros for rodent control and was immensely impressed with their service. Said Abdullah, our representative, showcased remarkable professionalism and efficiency, conducting a thorough inspection even under heavy rain. What stood out was Saidâ s attention to detail. He went above and beyond by cleaning our clogged dryer vent during the rodent proofing process, demonstrating a proactive approach to our safety. The communication from Attic Pros, especially from Sho in customer service, was consistently excellent. Shoâ s attentiveness and clarity in addressing our concerns were noteworthy. In conclusion, Said Abdullah and Sho are exemplary representatives of Attic Pros, embodying the companyâ s dedication to customer satisfaction and safety. I highly recommend Attic Pros for effective and professional rodent control services."

Types of Insulation

Insulation is designed to maintain a stable interior temperature regardless of the outdoor weather. There are four main categories for insulation. The type you choose depends on these factors:

  • The square footage of the area
  • The type of space
  • The effects of your local climate
  • Your budget
  • Your home's current R-value
    (R-value is the capacity of an insulating material to resist heat flow. The higher the R-value, the better it can keep heat in or out.)
Fiberglass Batts

Fiberglass batts are the most common and least expensive way to insulate your home. They are installed during construction and renovations before the walls or floors are closed in. Properly installed, it improves the energy efficiency of your home by 25 to 30 percent.

Blown-In Insulation

Blown-in insulation is made from white cellulose, a byproduct of recycled cardboard, newspapers and other paper materials. It provides excellent R-value which increases depending on the depth.

Spray Foam Insulation

Spray foam insulation is ideal for filling tight gaps and spaces that make a home drafty. It begins as liquid polyurethane that is sprayed into an opening or cavity. It expands to fills the space and then hardens into solid foam.

Reflective or Radiant Barrier

Reflective or radiant barriers work the opposite way as do other insulation materials but it has similar results. Most insulation slows down the flow of heat, but the thermodynamics of radiant barriers causes it to reflect the heat and cold. It is commonly used in attics to minimize the effects of scathing summers or frigid winters.

Cost of Insulation & Installation

The cost to purchase and install insulation varies regionally. The national average cost varies by material, with blown-in at around $880, fiberglass around $960 and spray foam around $1,100.
