The owner of the company negotiated a price that was fair and he promised to perform the work on Thursday and Friday of the following week when he had open time and because I was willing to contract immediately he discounted the service. He asked to write the check to himself Jeff Fine rather than Northern Virginia Insulation. He emailed me on the day he failed to show up to inform me that he was ill and would perform the following week. He promised to do the work on Wednesday and Thursday and failed to show and offered me the ability to cancel the contract and refund my deposit. I accepted and he promised that my deposit will be refunded as soon as a check he had from another job cleared his bank. He said that will be the following Monday. He did not refund my money then nor at any time after that despite his repeated emailed and texted promises to make payment by the end of the next week. I held off filing a formal complaint to give him a chance to prove his good faith. I am now one week past the last refund date that he gave me and I have received no communication and no refund so I am filing the formal complaint with Angi.

Great product, great customer service, great installation. No hassles with trying to up-sell me on additional products or services. Manufacturing the sliding glass door took a bit longer than I'd hoped, but otherwise, I'm very pleased.

The value is amazing, and if the install goes well, you will likely be very happy. As is, I was very happy with the pricing. The initial install went very well, save for a few minor issues. One of the issues was due to a manufacturer defect, so the blame isn't all on Eco. My main issue was simply with how long it took to get to complete satisfactory completion of the project. The original work was done in March 2017, which was within the timetable that Jeff gave us. All good there. However, getting to the 100% satisfaction mark took until August 2017. I don't think all the blame is with Eco Windows due to the manufacturer's quality issue, but it felt like after I sent final payment the priority Eco put on my job went down substantially.

Response from Company:

Jeff, I am sorry it took so long to get the replacement sash you needed. It usually never takes my supplier that long to get a replacement sash. We appreciate the work and you have a lifetime warranty with us. Please do not hesitate to reach out if you need anything.

We met with several window companies and we chose Eco as they had the best quality window for the price. We worked with Jeff and he was excellent. No hard sell, answered all the questions and he was responsive when we had questions. The installers were excellent as well. The windows came our great and they were extremely neat and careful. The quality of their work is outstanding. I woudl highly recommend Jeff and Eco Windows and Siding.

We had attic insulation added. Fantastic job and already after one night, huge difference in the overall temperature of our upstairs- the higher R value + radiant barrier is really keeping that heat inside the home. Can't wait to see my next few heating bills- job should pay for itself over the long run, plus we're no longer shivering cold in our house!

My project included a storm door and a sliding glass door. The project was to be completed within 6-8 weeks and we were told it would be more like 6 weeks. It took 7 months for them to finish the work. We did receive a $500 credit for the delay, but it took way too long as we were never made a priority.

Response from Company:

Note: Customer is a resident in my neighborhood. Job was contracted at cost initially. Explained delay and even even took $500 off of balance. Really sorry again for extended lead time. Custom doors can take up to 8 weeks just to get delivered. If a door comes in damaged, I will not install it and need to re-order product. Customer has a lifetime warranty including installation.

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.

    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
