When it comes to home retrofitting, choosing the right contractor is crucial to ensuring the success and longevity of your project. Whether you're upgrading for energy efficiency, enhancing safety, or improving the overall comfort of your space, having an experienced and engaged contractor can make all the difference.
On this page, we'll guide you through how to find a contractor who not only meets your specific retrofit needs but is also passionate about delivering high-quality, sustainable results. With tips on evaluating credentials, communication, and project compatibility, we’ll help you connect with professionals who truly care about your home as much as you do.
We're currently working on bringing together a network of qualified and engaged contractors but we can offer some criteria to guide you in your decision making criteria.
Experience
One great indicator when selecting who to hire is their level of experience. this is a natural indicator of their background knowledge and ability to perform the task. It also lets you find reviews of their work either online or from referrals. A caveat to this is that there are people starting new small businesses all of the time. Often these people have years of experience in their trade but have only recently started their business. When you are calling to get quotes ask questions about the experience level of their staff to assess their credibility.
Certifications
When selecting a contractor for home energy retrofits, look for certifications that indicate expertise and quality workmanship. The Building Performance Institute (BPI) certifies professionals in home energy auditing and weatherization, ensuring they understand building science and efficiency upgrades. The North American Technician Excellence (NATE) certification is a trusted credential for HVAC professionals, demonstrating advanced knowledge in heating, cooling, and ventilation systems. RESNET HERS Raters specialize in home energy ratings, providing insight into a home’s efficiency and retrofit recommendations. For insulation and air sealing work, contractors with SPFA (Spray Polyurethane Foam Alliance) or RPA (Residential Performance Alliance) credentials can ensure proper installation. These Certifications aren't particularly common but if you find a contractor who holds them they are a great candidate for your project.
Permitting
Most contractors and installers will handle the permitting process for your home retrofit projects. For projects without a contractor or installer, you will need to pull your own permits.
