"We had Everguard Home Insulation install Applegate cellulose insulation in our attic on 2/2/18. They did an outstanding job! Everguard was very professional and competitively priced. (We had four estimates. They were not the cheapest but their reviews were outstanding. They have had their license since 1964 which says a lot.) They arrived on time and the insulation was quick and clean. They moved furniture and cleaned up thoroughly. We highly recommend Everguard if you need attic insulation. Since the insulation, we have not had the temperature swings we had in the past. In fact, we have not had to run the heater in the early morning since the insulation was installed."

Eifs Installers FAQs, answered by experts

They meet local code demands for escape routes, lighten basements, and aid in reducing overall humidity.

Basements are generally required to have windows for your safety. At a minimum, windows should provide an egress in the event of a fire. But basement windows do more than offer a way out; basement windows also offer natural light and ventilation in an area of your home that is otherwise dark and musty.

To find and hire a reputable contractor for an egress window installation, you should first research local professionals and then vet your top candidates. Start by searching for local contractors who specialize in this type of work, read their customer reviews, and examine their website and portfolio. Once you have a shortlist, contact them to ask key questions: Are you licensed and insured? What is your specific experience installing egress windows? Can you provide references from previous customers? Do you perform the work yourself or use subcontractors? What is the estimated project timeline and your current schedule? How do you handle payment?

You install a window well 8 to 12 inches deeper than the base of the window sill. After filling the well with drainage rock, the well should sit 3 inches below the bottom of the window. The top of the window well should also be at least 3 inches higher than the surface-grade ground. The window well should be about 6 inches wider than the window opening.

Yes, egress windows can significantly add value to a home. By making basement and attic areas safer and more livable, they allow you to market these spaces as finished living areas, which increases your property's value. Many homeowners can recover the full installation cost, with some sources citing a return on investment of around 70%. The exact value added depends on your specific home, location, and adherence to local building codes. Beyond financial value, egress windows enhance functionality by adding natural light and comfort. They are also a crucial safety feature, often mandated by building codes to serve as an emergency exit.
