Q: Do I need to hire an electrician when I have insulation installed?

• <div><p>If you&rsquo;re moving wires, installing new wires, or installing new fixtures in the space you&rsquo;re insulating, then you will need to <a href="https://www.angi.com/companylist/electrical.htm">hire a licensed electrician</a> to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don&rsquo;t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they&rsquo;re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.</p></div>

Q: How long does garage door insulation last?

• <div><p>Garage door <a href="https://www.angi.com/articles/how-long-does-a-house-last.htm">insulation can last</a> anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. </p><p>Humidity plays a role in how long more susceptible insulation materials&mdash;like fiberglass&mdash;last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.</p></div>

Q: Does insulating an unheated garage cause mildew?

• <div><p>In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.</p></div>

Q: How long does it take to remove blown-in insulation from an attic?

• <div><p>Depending on the size, insulation condition, and removal method, it can take anywhere from four hours up to twenty hours. Therefore, be prepared to split the projects into phases, or leave it to a professional. Insulation is an intermediate project with various risk factors and can be challenging to someone unfamiliar with the process.</p></div>

Q: How do pros determine the right type and amount of insulation for my attic?

• <div><p>Through R-value assessments based on climate and existing insulation.</p></div>
