    "Wonderful and professional"

    Stephen Jowers-Wilding

    The crew from Viridian Retrofit was wonderful and professional. They did a thorough job taking the measurements and installing our new double-glazed windows, which turned out great. My family and I noticed that our corridor is now warmer through winter because of the retrofit  double glazing, and it has become a more comfortable living environment. We enjoyed their service so much that we have decided to employ them for more installation in the future.

    "Knowledgeable"

    Chu Tang

    When looking to retrofit double glazing in our house we had quotes from a number of companies. Viridian Retrofit were by far the most knowledgeable concerning the double glazing required for our house. They were also very reasonable when it came to the costing. The team of Piripi and Andrew instilled me with confidence, all the way to the end of the project.
