How to Find the Right Insulation Contractor

Skylight with energy efficient insulation around it

Home electrification is a great way to make your home better for the environment! By using all-electric systems and appliances that don’t run on fossil fuels, you are improving your home's energy efficiency and cutting your greenhouse gas emissions. 

But electrifying your home can only go so far in making it “green.” Adding insulation and air sealing into the mix helps further reduce energy waste, improves indoor air quality, and makes your home comfier year-round.

Finding the right California insulation contractor is just as important as finding the right home electrification company. Here are some things to keep in mind when choosing the best insulation installer near you:

1. Ask the Contractor for References and Reviews

There are a lot of questions you may want to ask a contractor about availability and pricing, but one of the most important things you should know is: Do they do quality work? Aside from word of mouth, there are many places you can go online to read reviews and testimonials from a California insulation company’s previous customers, including:

  • Their website

  • Their Google Business Profile

  • Third-party review sites like Yelp

See what other people are saying about the company (as well as how the company responds!) before you make your decision.

2. Check to See if the Contractor Is Properly Licensed & Insured

You might think you’re getting a great deal by simply going with the nearest insulation contractor near you, but if they aren’t licensed and insured, you could be opening yourself up to legal and financial trouble. A company without proper licensing is also less likely to offer quality work—if they’re cutting corners with paperwork, wouldn’t they be likely to cut corners on your home as well?

3. Ask What Types of Insulation the Contractor Installs

There are many different types of insulation, from traditional fiberglass batts (which you’d likely recognize by their pink color) to spray foam insulation, rigid foam board insulation, and cellulose insulation, which is a more environmentally-friendly insulation material made from recycled newspaper that’s been treated to be fire-retardant. Ask prospective contractors about the different types of insulation they use in different areas of the home—you want a company that is knowledgeable about the different options available and can work with you to choose the right insulation for your California house.

4. Find Out What Other Services the Contractor Provides (Are They a Whole House Contractor?)

Insulation for your California home is a great way to save money, improve comfort, and reduce your home’s carbon footprint. But it’s only one part of creating a greener home, and many homeowners would be relieved to find a whole home contractor that could not only upgrade their insulation and air sealing but offer additional home improvement services as well, like:

Finding a single company to handle all of the work is convenient—and it means you don’t have to go through the whole vetting process multiple times!
