"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

In most cases, the building code in your location will determine the minimum amount, in R-value, required for your home's walls, attic, and other spaces. For attics, the minimum R-value amounts start at R30 in the south, R38 in mild climate locations, and R49 in northern states and cold western areas.

Yes. You should insulate behind shower walls to help stave off heat loss. In other words, it’ll keep the shower or tub from getting too cold. Nothing ruins bath time like stepping into a freezing cold bathroom. Not insulating and air sealing the walls behind the shower allows heat to escape easily, which opens the area up to the elements. 

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

While fiberglass is dangerous to work with, it’s a perfectly safe material once it’s installed. If you’re tackling the installation yourself, make sure you take the proper safety precautions and wear the right gear to avoid skin and eye irritation and lung complications. Working with a professional insulation company can mitigate these risks.
