"

Insulating the exterior walls of our two story, 1700 sq ft house, involved drilling holes between each stud, blowing in insulating material, plugging the holes, spackling over the holes, priming and finally painting the holes.  Two man crew was very efficient in setting up scaffolding and then doing the work described.  We got a chance to see what the insulation looks like inside the wall when the force of the insulation popped out a built-in bookcase that was not secured.  Its a solid blanket of insulation, filling in the entire space.   Very impressive.  The results have been very noticeable.  The house feels more comfortable, and the heater turns on less frequently.  We should have done this years ago. 

Last part of the project was to blow additional insulation into the attic, which went very quickly.  Overall, the project took 2 very long afternoons/evenings to complete.  It makes a mess around the outside of the house, but they did a good job of cleaning up each day.

"Had a great experience hiring Bay Valley Insulation. The quote arrived very efficiently and was the price I was looking for. The crew of Tony and Henry arrived inside the scheduled window and work was completed in a timely manner that day. The job looked great in the blown attic and final clean-up was great. Thank you."

"This company came in a updated our 40-year old home insulation with new R-38 batting. We were impressed how much attention to detail the company has for removing old insulation, clean-up, disinfection, and installing new insulation. They also replaced a damaged dryer vent in the crawlspace. Nico and Jeremy were a great combo to work with from quote through install. I plan on calling them back in spring for another project."

"Attic Professionals was awesome to work with and highly recommend their business for anyone looking for attic work. We hired his business to replace the insulation in our attic after I took care of a rat issue. We needed all the insulation and droppings removed, cleanse, and replace. Attic Professional crew were diligent with making sure the interior of our home was protected covering the walls and floors to remove the old insulation and did a great job installing the new insulation. Thank you for great service!!!!!!!!"

Insulation questions, answered by experts

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

Yes, you should insulate your copper pipes to help regulate their temperature. Well-insulated copper pipes will be protected from freezing and can conserve energy by keeping hot water warm for longer. Foam rubber insulation tubes are the best pipe insulation to prevent freezing since they fit tightly around the pipes while still maintaining some flexibility.

Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for. However, the material may degrade sooner in areas with high humidity or after prolonged water exposure. Proper installation and maintenance can maximize its longevity but requires close monitoring. Closed-cell foam insulation has a longer life span of 30 to 50 years.
