"I’m a land lord of 72 residential properties and the biggest head ache other than common upkeep was the constant battle with roaches and insects inside the units, I had Triple B come out and put their pest control infused insulation at 10 of my properties and within 3 weeks the tenants were in shock at how affective it was, they went from seeing them everyday to hardly ever, I ended up getting them to do all my units and also my own house, this will be a must at any property I ever purchase, highly suggested for new home owners/buyers"

"He was very knowledgeable and professional. After the audit we received an estimate to correct any areas that were discovered. Unlike what we originally thought our issues were not the windows and doors. The estimate was for $4000 to add insulation to the attic, increase airflow in the attic, install foam insulation around our fireplace and throughout the basement as well as removing the attic fan and adding drywall.
The price is the estimated price for projects to be completed.

"The fellows did a great job with this house. The work is really quite excellent, and they kept us informed with how long it would take, how it was going, and could speak in understandable sentences. They were polite and they worked very quickly.
We were amazed and how quickly they did this job, as it was perfect and not at all sloppy, which you easily see in others who are quick and sloppy. They were anything but. They cut around several outlets and exterior items on the house and that was done well. I would definitely recommend to anyone. We also cannot believe how much WARMER THE BACK OF THE HOUSE is now - especially as it faces NORTH and was quite cold for the last 15 years. We hope to be able to have them do the rest of the house as we like the insulation put in and the type and quality of siding that was used. We would recommend most definitely."

"My best friend's mother had been challenged with sickness for quite some time. She had been complaining about mold in her house. We had several people come out and do inspections. Most of them were expensive. We could not meet their requirements at the time. We finally called Absolute Clean. They came out and did a thorough inspection. He actually found the mold problem that the other companies never mentioned. He gave us a detailed description of how it would be removed. We hired them for the job. They did an excellent job. They were completely knowledgable which made them able to do an exceeding job. They came in and removed the mold. They removed some paneling and drywall that had been previously missed by the other contractors. They scrubbed the mold. They chemically treated the mold problem. They actually ozoned the whole premises to get rid of all of the mold. They also found asbestos insulation that was missed by the previous companies we had to come out and look at the problem. They removed the asbestos for us. They worked around our time schedule which was a great help. They were very courteous and polite. I would recommend them highly."

When choosing a professional insulation installer, consider asking these questions to determine the best fit.
Will you address air leaks in my house?
Can you provide an R-value (heat resistance) fact sheet?
What kind of insulation will work best for my home?
How do you handle signs of a water leak?
Are you licensed and insured?
Can you provide customer references?
The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.
In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:
High heating and cooling bills
Uncomfortable room temperatures
Ice dams on the edge of your roof
Roof leaks
Cold floors and walls
Freezing pipes
Temperature fluctuations
Visibly low insulation
Noise problems
Pest problems
On average, insulating an attic costs about $2,500, ranging from $1,500 to $3,500, depending on the insulation type, amount, and your attic’s accessibility. Additional cost factors include sealing air leaks, removal or replacement of insulation, and inspections. Types of insulation include:
Blown-in: $1–$4 per square foot
Spray foam: $2–$5 per square foot
Batt: $2–$4 per square foot
Structural insulated panels: $4–$7 per square foot
Loose-fill: $2–$5 per square foot
Reflective: $0.50–$1.50 per square foot
