"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."

"Ahmad from GreenShield is very professional and provides excellent customer service. I was looking for a company to finish my insulation project as I had to fire Attic City for their poor customer service and terrible rodent proofing. Ahmad was extremely helpful in connecting me with another rodent company and also helped me find another company to install new ducts. Ahmad followed up with me regularly and informed me of a rebate program for the insulation and duct work. I am super grateful for Ahmadâ s help and I highly recommend GreenShield. If I could give more stars I would!"

"I love this company! Garrett came to my home and assessed how efficient our current insulation, etc was. He was very informative and friendly — explained what we needed and how they could help. At the time, I decided to hold off and he never pushed the sale. When I was ready, he was quick to accommodate my schedule. His team: Angel, Luis, Tommy and TJ were great! They arrived early, were professional, courteous, kind, very helpful with my questions and were above and beyond to help fix things that I wasn’t even aware of. They also were more than happy to help with small problems that I had no idea how to fix. They worked quickly and cleaned up afterwards. You could tell they cared about their work which makes me feel confident that the job was done right. They were also fun to have around — my Great Dane loved them too! Garrett and Dave checked in with me during and afterwards to make sure things were going well and if I had any questions. I highly recommend Eagle Shield."

Insulation questions, answered by experts

Bubble wrap is better for moving since it can be cut to size, whereas dish foam comes in precut sheets that are harder to manipulate. However, if you’re packing items like dishes, wine glasses, picture frames, or mirrors, dish foam will protect them better. Ensure you measure your box beforehand so you know what size dish foam to purchase. 

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.
