"Old shake roof was removed, new insulation added, plywood base with roof paper cover. Then tiled over raised battens. New gutters and downspouts. Dry rot repairs and painting of new surfaces.The whole process took four days. The bid and contract were presented very thoroughly, each item of work detailed and priced. Many choices. The work crews were very pleasant. The work was done in a set order and a company rep would call to inform of the next step and when it would happen. At the conclusion of each days work the property was cleaned and as tidy as possible given the nature of the project. When finished, a company rep inspected the job and checked for any needed corrections. All in all, an outstanding contractor to work with."

"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."

"we were very impressed with out solar endeavor. The installers came when they said they would and finished their job within the same day. We added insulation to our attic to reduce our heating and cooling for the house and replaced 2 old windows . All the guys were great from Idan who evaluated our home, office staff and installers. We are very happy. "

"An unanticipated extra expense, but they removed all attic insulation and pumped in new insulation with 3X the protection. Closed up all possible entrances into house; made three trips. So far, no signs of these pests, but they say call anytime if I see signs. I'm moving and I can't -- with good conscience -- sell this house to others knowing it had rodents, although it didn't seem to bother the people I bought the house from."

"Excellent. The rep showed up on time and did a very thorough job, complete with photos and a write-up of all the affected areas. He also gave a quote to perform both the exclusion work and to clean & replace the soiled insulation. I will be calling them to do both jobs shortly."

"Due to some renovation and repair work, there were large areas of ceiling over the kitchen and master bath where the insulation had been removed. The rest of the house had old cellulose insulation that had been settling for several years. All in all, in the winter cold the lack of insulation was noticeable. RJL Installation ran a special with a discount on Angie's List to pay $149 for $500 worth of installed attic insulation.  I bought the special and was contacted by RJL. I was really only wanting the areas where insulation was missing to be covered, but it turned out that the cost was not much greater to get the entire attic covered. I was somewhat taken aback by the total price ($1,149.50 on top of the original $149.00), but decided that the insulation was needed in any case, so that was why I gave the C rating for price. I felt a bit trapped because I had already paid for the discounting and didn't know how to get that money back if I had decided that I didn't want to pay as much as the final quoted price.
The installer thought that there should be some sort of access port or window or something to get into the attic from outside the house, and seemed surprised that the house was built with only a hallway ceiling opening for attic access. Once we established that that was, indeed, the only way to get up there, the installer proceeded to bring a large hose through the front door and the hallway and into the attic. When he was in place, his assistant started feeding compressed bales of fiberglass-like insulation through a machine that broke up the compressed insulation and "fluffed" it and blew it through the large hose to be blown in place. When the installation work was completed, I was invited to climb the ladder to take a look at the coverage, using a large flashlight as my light source. From the ladder, the insulation looked to be level across as much of the attic as I could see (almost all the attic, in truth), and appeared to be deep enough to be effective. When they were finished with the installation, the installer and his assistant borrowed a broom and managed to sweep up almost all of any insulation that had found its way to where it was not wanted.
All in all, an acceptable job. I thought about giving an overall rating of B, but except for the price, the other categories rated an A.

Insulation questions, answered by experts

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

The average U.S. homeowner pays $1,850 to insulate their home. However, the cost of insulation depends on the type, the size of your home, and who does the installation work. 

The cost of foam board insulation depends on whether it's made from expanded polystyrene (EPS) or extruded polystyrene (XPS). EPS has the lower price point, usually costing between $0.25 and $0.50 per board foot, while XPS costs between $0.40 and $0.50 per board foot.

You’ve likely heard the saying “heat rises”—well, it’s true! This is why it is critical to properly insulate your attic and protect yourself from chilly winter nights. During summer, your attic insulation will also protect against excessive heat gain radiating through the ceiling into the rest of your home below.

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.
