How Long Does Blown-In Insulation Last? When Do I Need to Replace in My Attic in Aliso Viejo, CA?
Blown-in insulation is a common material and method used to insulate unfinished attic spaces. As home’s age, or if the insulation has gotten wet or damaged, it will need replacement to properly insulate your attic. When the time comes and you need to replace your insulation, there are a number of tasks that need to be completed. When it comes to replacing insulation, it is definitely not a do it yourself job. It takes a professional like Laguna Bay Developing. We will explain the steps of replacing blown-in attic insulation below.
Step 1. Remove Old Insulation from Attic
Most modern homes were built using blown-in insulation that contains cellulose fiber. If the home was built in the 1950’s or older, it most likely contains asbestos. You can get an asbestos testing kit and test the insulation yourself. However, if the test shows that the insulation does contain asbestos then you should hire a professional contractor to remove the insulation for you. They are trained and are more equipped for handling the job. If the insulation is asbestos free, you can rent an insulation vacuum to remove the insulation. Make sure to wear eye protection as well as a respiratory mask.
Step 2. Prepare for Proper Attic Ventilation
Before you have the attic re-insulated, you will want to make sure you take certain steps first. It is important to have proper attic ventilation. Each home ventilation system can vary. However, in most cases, ventilations in unfinished attics have a fresh air intake vent located in the soffits. In addition, there is one to two other exhaust vents. They are typically near the gable or at the roof’s peak. Make sure all the attic vents are clean and clear of any obstructions to promote proper air flow.
Step 3. Install New Blown In Attic Insulation
Professional contractors use a blower machine to spread the fiberglass insulation into the attic. It is important to properly insulate the attic for proper heating and cooling efficiency. The insulation is blown in-between the rafters, and depending on your home insulation needs, there is anywhere from 6 to 12 inches of the fiberglass insulation installed in the attic.
How Can You Tell if Insulation is Bad & Needs to Be Replaced?
It is important to replace your attic’s insulation when it needs to be done. However, it can be difficult to know when to replace the insulation. There are a number of signs to watch for such as:
– Cold or Hot rooms, walls or ceilings
– Drafty rooms or uneven temperatures between rooms
– High heating or cooling utility bills
