"I'm very satisfied with the quality of work this company does and the price was very fair. Aaron, the owner, was easy to talk to and after a short discussion, he knew exactly what I wanted. Mike and Dan did the insulation and even replaced a few floor boards at a nominal cost. They politely answered all my questions and you could tell they enjoy their work. If you want a professional job done at a very reasonable price, I would definitely give G.E.G. Enterprises a call."

"Bulldog was very knowledgeable and did a great job installing the insulation. I had to have them come back out to take a look at some of the insulation that made it's way into my basement, but they were very timely in getting this resolved. Overall, a great experience at a great price."

"I can't say one thing bad about this business: very professional, reasonable price, and they cleaned up that you would not know they were ever here. I will certainly recommend to anyone adding insulation to their house and like us insulating the garage. Excellent job to Hassan and his team."

"My crawl space insulation was dripping wet which made it virtually worthless. They removed the existing fiberglass insulation, and spayed foam insulation to replace it. I was quite happy with their professionalism, care for travel over carpet, quality, and for a reasonable price."

Insulation questions, answered by experts

Garage door insulation can last 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. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—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.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.

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 cost to install or upgrade insulation generally ranges from $1.50 to $4.00 per square foot. The final price depends on factors such as the type of insulation chosen, the total area to be covered (home size), and local labor costs.
