"We couldn't be more pleased with the added insulation in the attic above the garage. Only downside is that it's better done than the rest of the attic! The rest of the work replacing the insulation in water-damaged areas went very quickly. We will likely be bringing them back to do the rest of the attic."

Insulation FAQs, answered by experts

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.

Monolithic slabs don’t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction. This can help improve home efficiency even more and keep indoor temperatures more stable. Slab foundations are more energy-efficient than uninsulated crawl spaces and basements, and insulated slab foundations are more energy-efficient than insulated crawl spaces and basements.

Experts use advanced techniques and tools to assess existing insulation levels and identify gaps. They implement strategic placement of new insulation to ensure complete coverage, optimizing thermal resistance and energy efficiency.

You won’t find anything inside a cupola on a house because it’s hollow (think of an upside-down cup), allowing air to ventilate out of a roof via vents and light to come in via windows. They also usually have a base, vents around the middle (usually louvers), and a pointed cap at the top.

When looking for a company who installs insulation, your best bet is usually to work with an insulation contractor or professional insulation company. If you can't find a local insulation company, working with a general contractor can be another option. No matter who you hire, always confirm that they have experience.
