"I give this company an A for doing the job for a good price. I give them an overall grade of B because if you need them to come out and make repairs on the work they just finished, you have to text message them every day to get them to come out. I have one piece of siding that needs to be put back up, and have been waiting more than six weeks because I forget to text them every day. I really want to give them an A, but I just can't. Have been waiting too long for them to re-hang that one piece of siding."

Insulation questions, answered by experts

You can purchase bags of cellulose and loose-fill fiberglass blown-in insulation from the same local home improvement store where you rent your blower. If you want to use rock wool insulation, you may need to special order it.

You can insulate an existing garage door. But while it’s a cost-effective option upfront, it may not perform as well as a garage door that comes with insulation. If you live in a colder climate—or if you plan on working in your garage and need a new door—you should purchase one with existing insulation for better efficiency. 

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

If you have bubble wrap lying around the house and you don’t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.
