Many homeowners inquire about removing the old insulation from their attic, rarely is this necessary. The only time we recommend removing old insulation is when the insulation has been fire damaged, water damaged or heavily infested with rodents.
Most homes have some old or “existing” attic insulation already in their attic. Typically we just add more insulation to what you already have in order to bring the attic up to an R-30 or R-38 rating. The existing insulation may be dusty, filled with old roofing debris and look quite tattered, but it’s just old material; it doesn’t contain asbestos nor contain anything that wouldn’t be rendered safe once new and fresh material is installed over it. Also, there’s no chemical interaction or problem with mixing various insulation materials either. We actually can save you money by using your existing insulation as a base and installing enough additional material over it to bring the attic up to R-30 or R-38.
In the rare instances where insulation removal is required, we hand-remove the fiberglass rolls and pack them in bags that are carefully removed from your attic. If the attic has blown material, we use a large vacuum to remove all the material. The vacuum is usually outside the house and this creates a “negative pressure” in the attic such that air is being drawn up into the attic, this ensures a clean job where little or no debris enters the home.
Vacuuming and removal is a very labor-intensive and time-consuming task. We generally need a whole week’s notice to get to a job and it may take 1-2 days to complete. We charge by a price per square foot, please call our offices for a quote.
Most insulation removal is based on rodent infestation, and Everguard is very proud to say we’ve saved customers thousands of dollars over the years! All too often homeowners figure all the insulation needs to be removed from the attic, this is rarely the case! More often than not, rodents congregate around the furnace or a few other spots. Because there are usually just a few areas affected, we offer “Spot Removal”, which very simply means we remove the insulation and debris around the various areas where the rodents were. No need to remove 100% of the insulation when only 2% of the insulation is affected. You wouldn’t remove all your teeth just because you have a few cavities? No, you’d just remove the decay and probably give your whole mouth a cleaning. That’s what we do; we remove the infested areas and generally add more insulation to bring the entire attic up to R-30 or R-38. Oddly enough, it’s often through a report of rodent infestation that homeowners discover they don’t have enough attic insulation to begin with! So we not only help them with the rodent mess, but also to save money on their utility bills and keep the house much more comfortable in both summer and winter.
Another point to mention is that fiberglass insulation (rolled or blown) makes a welcome home to rodents and insects. Over the years, we’ve only seen rodents nesting and living in fiberglass. When we clean the rodent mess and then install the cellulose material, beside the improved thermal benefits, the rodent and insect resistant qualities of the cellulose tends to ensure no more rodent or insect visitations.
