Our Process

At RetroGreen Energy we have a multi-step process for every project that ensures superior quality and customer satisfaction.

Step 1: Educate

We take the time to share the value and benefits of an insulation retro-fit for your home. We start with a FREE in-home consultation where you will learn about our products, the installation process, the opportunities you have to improve your home, and financing options. All your questions will be answered. This is done at no cost and with no obligation to you.

Step 2: Investigate

Our certified diagnostic experts provide an on-site, in-depth physical investigation of your home. In order to fully evaluate your home and design an effective thermal boundary, we need to get dirty! During the investigation process, you can expect us to climb around in your attic, crawlspace, and basement to determine the site of leaks and the scope of the work.

Step 3: Formulate

Based on the needs of your home, we design a custom retrofit with our best recommendations to improve your comfort and save money. Our pricing is itemized. We will help you decide which needs are the highest priority. You can complete the project all at once or in phases depending on your budget.

Step 4: Retrofit

In just one day you can give your home peak performance to last a lifetime. Our professional installation teams thoroughly retrofit your home with a superior quality, custom installation system. Most residential projects are completed in a day or less. Even very large homes can be completed in two days.

We don’t have to rip your house or life apart! We do most of our work from the outside or in areas you don’t live in such as the attic and crawl space.

Our entire crew represents RetroGreen Energy with friendly professionalism and expert skill on the job site. They are paid and treated as professionals which means they value their job, take pride in their work, and have the experience and consistency do it well. Our crews are always led by a BPI GoldStar foreman.

Step 5: Finishing Details

Our crew transforms their “work site” back into your home, just the way you had it, maybe even cleaner. When our work is done, there is nothing left for you to do but enjoy the increased comfort that will begin immediately. We even haul away all refuse.

Step 6: Post Project Packet

You will get a custom-made post-project completion packet. Use it to review our work and prove the increase in your home’s value. The packet is an impressive collection of pictures of YOUR home, before, during, and after, with a narrative about what was done. Keep it in your house folder to present to a real-estate agent or potential homebuyer should you want to sell your home in the future.

Step 7: Return your Investment

Payback begins immediately! We guarantee a lower utility bill.

We dare you to compare your utility bills before and after the project. As prices for fuel increase, your payback multiplies. The increased durability and quality of your home will also prevent some future maintenance expenses (like exterminators, mold mitigation and furnace replacement.)

Our goal is for you to refer at least two people to us. That’s a pretty bold statement. However, we know that our retrofit projects are so amazing, so needed, and so valuable that you won’t be able to stop talking about how much better your house is! You will be excited to share the opportunity with your favorite people so they save money and be just as comfortable at home as you.

You earn unlimited $100 rebates from referrals, so spread the word. All previous customers earn instant access to our affiliate program. It’s simple. Just refer a friend or neighbor to RetroGreen Energy. When that job is completed, we send you $100. There is no limit to the number of rebates you can get.
