"It was about 30 degrees outside and around 45 inside. Furnace not coming on. I went to Home Advisor to setup a quote and I was still considering the three recommendations, when the phone rang. This guy was on the ball! He was at my home in less than 30 minutes and had diagnosed what was wrong, fixed it, made some recommendations, upgraded my old thermostat and got us up and running in no time! He even did some extra maintenance for free. Very good service. Very friendly and professional. We definitely will use him again."

"These guys are great! Manny showed up on time for his estimate, gave me a price on the spot, and talked things out with me to make sure that I understood exactly what he was including in the insulation project. He was able to meet my timeline, which was quick, and finish the project on time and as promised. He was very communicative throughout the process and pleasure to deal with. His crew was polite and worked hard. I am VERY satisfied with the crew and the workmanship."

"They showed up exactly when they said they would. They were efficient, neat and made sure to send me pictures in the various stages of execution. And they cleaned up better than when they found the area. I would highly recommend them. I wish he did more than insulation because he would be my go-to guy for all house related needs."

Insulation questions, answered by experts

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed

One of the biggest disadvantages of glass garage doors is that they are not the best at insulating your garage. In the summer, heat can enter through the glass, while in the winter, heat can escape through the glass, increasing your electricity and gas bills as you crank up your HVAC unit. You can help mitigate the poorer insulation by investing in insulated glass and insulating your garage.

Although spray foam insulation typically has a higher price point than traditional insulation, the benefits often justify the investment. It offers superior sealing properties, which can lead to significant energy bill savings. Spray foam also provides excellent moisture resistance and soundproofing. Other advantages include improved indoor air quality by minimizing allergens, a long lifespan of 80 to 100 years, added structural strength to the home, and a straightforward installation process.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

You can buy pipe insulation materials in your local hardware store or in major home improvement stores. You can also shop for insulation online, where you may be able to more easily buy in bulk. When shopping, make sure you know your pipe's dimensions so you can buy the correct size of pipe insulation materials for your pipes.
