    Dear Gene and Gina:
    We understand that you are the owners of WeatherSeal; and, as such, we wanted to express our appreciation to you for the excellent service provided by your company this year in response to our need for mold remediation in our basement.
  • B. Barbour, Roanoke, VA

    Just heard from our basement renter, she hasn't had one drop of water in her apartment since the new gutters have been installed! Praise the Lord! It sure has been a pleasure getting to know you and having you work with us on our property.

  • J. Cashman

    That went very well. The entire crew was very pleasant and left the house in perfect condition.

  • Jane G.

    The whole house cools better than before!

  • P Bingler.

    Your employees are very nice and we can feel a difference already in the house. Very happy with the work and results. Should have done this years ago!

  • Lt. Col. C. Byrom, Crozet

    Your team did an excellent job, and we really appreciate it. Whenever I meet someone who needs insulation work, I will happily recommend your company.

  • Matt G

    I wanted to write to share my very pleasant experience with your company. James was the salesperson who came out to the house. He was very knowledgable and professional, and also a very nice young man. The installers were also very professional, courteous, and did a great job.

  • Jeni K., Schuyler

    They did a great job! They are very intuitive and can look at the house and how it works as one system, then figure out what needs to be done. They are prompt and on time. Communication is excellent!

  • B. Byrne, Reva, VA

    I really appreciate the great job that you did. I will let the building inspector know that he steered me in the right direction and if you ever need a reference, please feel free to use me any time. Your work was done as well if not better than the best I have ever seen.

  • J. Jennings, Charlottesville, VA

    The guys came out and did a great job. They were really friendly and helpful, and gladly tolerated my questions and concerns. I appreciate the fact that they invited me to look at the progress of each phase of work as it was completed.

  • J. Colony, Ivy, VA

    I would like to compliment you on the pair of installers you sent to my home recently. I was greatly impressed by their courtesy, their efficiency, and their attention to cleanup. I feel they represent your company in a very professional manner.

  • D. Snow, Charlottesville, VA

    Thank you. We have noticed a tremendous difference since installing the insulation.

  • J. McConkey, Afton, VA

    Thank you! It was a pleasure dealing with you. Wilson and Michael are the best! Very knowledgeable and professional.

  • T. Coffey, Charlottesville, VA

    Many thanks for a job well done. Your crew was efficient and thorough and the work was done in a timely manner.

  • Rebecca W. Mill Creek, Charlottesville, VA

    Thank you to the Weatherseal team! My house has a totally different feel to it after getting insulation yesterday from your very professional team.

  • Leatha H., Charlottesville, VA

    Thank you so much! You can always use me for a reference, you did a great job.

  • Stanardsville, VA, Stanardsville, VA

    Many Thanks! and Congrats to your team, Wilson. I'd be delighted when time allows, have Weatherseal go over every INCH of this old house. There are many areas that lack proper insulation and I'd be more than happy to identify and and "fix" as many as possible. A grateful, warm-- Carla H.

  • Elaine T., Gum Spring, VA

    Well, I am so grateful to Weatherseal who insulated my reconstructed 1840 house and sealed my crawl space. It was -9 last night here in Bumpass...and we lost power for two hours. All my pipes are still unfrozen this morning and the house is nice and snug.

  • Elliot G

    Weatherseal was GREAT to work with. The were timely in responding to email and setting up appointments as well as did their job quickly and professionally. I would highly recommend them.

  • Lindsay H

    I was very pleased with the rapid response to working with Wilson and his crew. They were very clean in removing the old insulation and getting the work done in a timely manner. I would highly recommend this company.

  • Gary G

    We hired Weatherseal Insulation of Charlottesville after receiving a recommendation about them from our LEAP representative.

  • Carla H

    Many thanks to Weatherseal and Wilson! I am very happy with what your crew has done for my house. As more areas become accessible, I will continue to ask you to assess and insulate! Again, many thanks!

  • Nancy

    The gentlemen that took the insulation out & put new back in the next day were great! They did a wonderful job! I will always recommend you! Thank you so much. The guys went the extra mile to make the work perfect!

  • Carla, Stanardsville, VA

    Many thanks! I am very happy with what your crew has done for my house. As more areas become accessible, I will continue to ask you to assess and insulate!

    Thank you for your timely phone calls Monday morning and for quickly pulling my job together, including sending Michael and Luke. I look forward to recommending your company in the future.

    Thank you so much! Michael explained everything to me in a manner that was easy to understand. It is important to me to understand how things operate and he was very helpful. Thanks again!

    We had an outstanding experience with James and Weatherseal - by far the smoothest of our house flip. He was incredibly knowledeable and professional and we will certainly recommend Weatherseal. Thank you.
