Insulation, when done the right way, can last for decades at a time. Moreover, it can improve the value, efficiency, and overall function of you home. That is all assuming that the installation quality is correct. When installed improperly, it can damage both the insulation and your home.
With poorly installed insulation comes the increased risk of drafts, mold, mildew, moisture, and more. Worst of all, those things will lead to an increase in your utility bills, resulting in more ways to pay. While it might seem like a simple installation, there are a lot of things that can go wrong. Entrust the process to your local pro and see the difference they can make.
