Only an inspection of your attics and crawl spaces can truly tell you what's your needs are. Throughout time a lot of unforeseen things happen in these spaces. Rodents, birds, water damage, broken ducts, mold issues, just people doing working these spaces can disrupt the system and make it ineffective. Proper ventilation is also another Factor. With almost 20 years in the field and an employee at Attic Projects I can say there is never a bad time to get your attic, crawl space, and perimeter of your home inspected. Especially if your home is older or it has been some time since you visited these areas of you're home. And yes there are many dangers to trying this yourself. That attic projects we have a great team of qualified people just waiting to do this for. I hope this was helpful and hope to hear from you soon.
Insulation should be replaced because of water damage, old age, or a rodent infestation. When it comes to old age, the current innovations of insulation are far more effective than the insulation from ten or more years ago. We recommend to remove old insulation and install a new one with a higher R-value, saving your electric bills from using the heater or AC systems.
