7. It’s Harder Than You Think – Hire a Professional
Even though adding insulation is a relatively simple project on paper, you may find that when you get into the finer details, it turns out harder than you think. That’s when it’s time to turn to the professionals.
Qualified contractors will know the answer to all the questions you have. They’ll know what type of insulation to use, and the recommended R values for different parts of your home, based on your location’s climate. They’ll know your state and local regulations, whether or not a vapor barrier is required, and on which side of the wall it ought to be installed.
Professionals also have a lot more experience, to they’re likely to know how to handle whatever odd complications that arise. They can measure the amount of fill going into the wall cavity. If it’s lower than it ought to be, they’ll know the fill is probably blocked by some obstruction, and how to get around it. They’re also going to get the job done a lot faster and easier than if you try to do it yourself.
