Specializing in Energy Saving Insulation, Window and Door Installations! We have evolved from a multiple crew to a one crew company. This reduction in size has allowed us to deliver the high level of service our customers have come to expect. Direct supervision by the owner on each and every project, as well as family members involved can eliminate the concern of "Who will be working in my house?" Cost is determined by the job and all estimating is performed by the owner. No travel charges. We are proudly not a Mass Save contractor.

"Calnan Energy promptly gave me an estimate to replace our damaged bulkhead. They were professional, punctual and very patient explaining the process. Very quick response getting the estimate and getting my job done. It's a family owned and run company - could not have been any nicer and did a meticulous job installing my new bulkhead. The price was very competitive."

Insulation questions, answered by experts

The best type of insulation for your home will largely depend on your climate and the space in your home you are trying to insulate. Fiberglass, for instance, is excellent for cold climates as it has a high R-value and won’t settle much over time; spray foam works well for humid environments as it has excellent moisture-resistant properties.

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

Closed-cell foam may come with a higher price tag, but it’s worth the investment because of its strength and durability. This material offers excellent thermal and moisture resistance, contributing to its long life span. Its construction enhances energy efficiency, which can lead to reduced heating and cooling costs over time.

Garage doors that are not insulated can be a major source of heat loss. That’s why it’s essential to winterize your garage door with insulation and weather stripping to prevent heat loss and keep it warm more easily. Consult a local garage door installer if you need help determining the cause of your garage losing heat.
