Should I remove old attic insulation before adding new?

• <div><p>Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: </p><ul><li><p>If the insulation is over 15 years old</p></li><li><p>If the insulation is wet or moldy</p></li><li><p>If it is <a href="https://www.angi.com/articles/what-is-vermiculite-insulation.htm">vermiculite insulation</a></p></li><li><p>If you see signs of pest infestation</p></li></ul><p>Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.</p></div>

Q: Can pros help you select the right type of spray foam?

• <div><p>Yes, guiding choices between open-cell and closed-cell foams based on needs.</p></div>

Q: Where should you not put insulation in the attic?

• <div><p>Don&rsquo;t install insulation near water heaters, oil burners, or any other object that gets hot. Many insulation materials are fire-resistant, but not entirely fire-proof, so you should take precautions to keep hot things away from fiberglass. This is also why it is imperative to box off lighting fixtures and breaker boxes.</p></div>

Q: Do outdoor faucet insulators work?

• <div><p>Yes! Outdoor faucet covers work by enclosing the faucet with a thick, insulating material that will keep the faucet warmer than outdoor temperatures. They need to be sealed tightly against the house to work properly, though, so be sure to tighten the rubber strap or drawstring on the insulation cover to best protect your faucets.</p></div>

Q: How thick should floor insulation be?

• <div><p>The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn&rsquo;t prevent ventilation, it can be as thick (or thin) as you need.</p></div>

The planning was good, the workers were hardworking and polite, the results were excellent. After suffering with incompetent contractors in the past, it was wonderful to have a group that had pride in doing a good job. I plan to use them for future projects.
