"I met with Milo (Field Tech/Sales) and he was great to explain their service and what I should expect. He provided an emailed quote to me on the spot as well as a copy of their insurance documents, bus. license number and proof of their "Diamond Certified" status. We had terrible rat problems in the attics and inner walls and needed to have our old insulation removed, attics sanitized, the entire crawl space/attic perimeters, and tops and bottoms (in attics and under crawl spaces) of interior walls rat proofed with small mesh wire and expanding foam. Also had mesh wire installed behind the crawl space openings that we could pretty easily still remove and replace when we have to get into the crawl spaces. Once we decided to go with Atticare I asked Milo to please send out a well-experienced, thorough crew to rid us of the severe rat problems as we were literally getting rat mite bites. He sent out Danis and his team to do the job which was for aprox. 1900 sq. ft., one-story, duplex. The team of about six fellas arrived on time, and immediately went to work. They did have some initial problems with the large vacuum machines. One would not start and one did not work at all. We had jumper cables though and they quickly got one going and went to another job site nearby to get a second vacuum machine. I thought they would not get done in one day because of the delay but the guys worked very diligently to get the job done and completed the job in one day as initially mentioned by Milo. I was present for the job which REALLY helped as I could easily communicate to Danis where we were really seeing the rat chewing damage, where we thought they were getting into and around the underside of the house crawlspace, and what wall they were really making a lot of noise in. Danis said I made his job a lot easier because I was present to alert them of problems we were having and where. So if you can be home to provide any "heads-up" on the specific problems/areas you are having the rat problems I think it really helps. Danis showed me before and after pictures throughout the job. Allena, the office mgr., emailed the pictures to me after the job was complete (and even called me on a Sunday, to remind me of my appointment which was early Monday morning). The fellas did very nice neat work and even covered areas with plastic sheeting in the garage where they had to crawl up to access the attics. Clean-up was perfect. The fellas worked well together too. I would definitely recommend Atticare/Milo/Allena and Danis' crew as the whole experience was excellent. Their price quote was very good too, compared to another "Diamond Certified" company that I received a quote from. I found everyone to be very professional and courteous. It has been a week since our service appointment and we haven't had any rats return! Thank you Atticare for a job well-done."

Frequently Asked Questions
What is insulation?

What is insulation?
Insulation is material that provides a barrier within a home’s walls, ceilings, and floors to regulate temperature and noise. If your home gets overly hot in the summer and cold in the winter, it’s likely not insulated properly.
Insulation efficiency is measured by R-value, which determines how resistant different types of insulation are to heat flow (or energy loss). R-values are measured by inch of thickness. The higher the R-value, the better the performance and the higher the price.
How much does insulation cost?
+
How much does insulation cost?
Our project data lists insulation costs between $1,400 and $6,300, but your final price will depend on the type of insulation you choose, its R-value, and how much you need.
- Fiberglass insulation: $0.30 – $1.50
- Blown-in insulation: $1 – $2
- Spray foam insulation: $0.50 – $2
- Radiant insulation: $0.20 – $1
- Rigid board insulation: $0.25 – $1
Luckily, insulation is one of the best investments you can make in your home—it has an ROI of at least 100%, meaning you’ll likely make back what you spend in a few years or so.
What is insulation made of?
+
What is insulation made of?
Insulation is made of many different materials, which can also impact the R-value needed for energy efficiency.
- Fiberglass: The most common insulation material made from glass. Fiberglass is a skin and lung irritant, so you’ll need to wear gloves and clothing when working with fiberglass insulation.
- Cellulose: Made from recycled paper products, plus borate for fire and insect resistance.
- Foam: Made from polystyrene, polyisocyanurate, or polyurethane plastic. You can also install cement-based foam insulation using rigid foam boards.
- Mineral wool: Made of fire-resistant rock wool, a mix of natural materials, or slag wool, made from a molten metal product.
- Natural fibers: Made from various recycled natural materials, including cotton, sheep’s wool, and straw.
Where is insulation in a house?
+
Where is insulation in a house?
If your attic is unfinished or you’ve ever demolished an interior wall, you might notice batt or spray foam insulation between the studs. Putting insulation between your walls and floors helps keep your home comfortable and your energy costs down. In addition to walls and attics, you can install insulation in your garage, in floors above vented crawl spaces, and basements.
- Garage Insulation: $0.50 to $1.25 per square foot
- Floor and crawl space insulation: $1 to $5 per square foot
- Basement insulation: $1.50 to $2.50 per square foot
- Wall insulation: $1 to $4 per square foot
- Attic insulation: $1,500 to $6,000
- Roof insulation: $1,500 to $4,500 or more
What are the different types of insulation?
+
What are the different types of insulation?
There are a few types of home insulation, and they all are made of different materials— most commonly, fiberglass, cellulose, and foam. Insulation includes these materials in the following forms:
- Loose-fill: Also called “blown-in,” loose-fill is sprayed into wall cavities, attics, and other oddly-shaped areas using special equipment. This insulation is usually made of fiberglass, cellulose, or mineral wool.
- Batts: An affordable insulation blanket best for unfinished spaces, such as between framing, studs, or joists. They come in pre-cut sections suitable for DIY installation and are mostly made from fiberglass, though other versions are also available.
- Rolls: Similar to batt insulation, but comes in rolls. Its make-up leaves less chance for gaps between sections and is more efficient than other types.
- Foam board: One of the most popular insulation types that can be used almost anywhere in your home. Foam boards also have a high R-value.
- Spray foam: Expands and hardens to fill gaps, small and large. Can be closed-cell or open-cell, but closed-cell has a higher R-value, making it more expensive per square foot.
- Radiant barriers: Does not reduce heat flow but directs heat away from the home instead. Radiant barriers are DIY-friendly and affordable, but they won’t be as effective in the winter months.
