    Attic insulation: More than 1000 sq ft

    NDS was very professional, from the person who initially responded to our enquiry to the person who provided the estimate and all the way through to insulation. They showed us pictures of the attic, where there were issues and “after pictures”. They did exactly what they said they would do and wanted to ensure that we were completely satisfied before they left. I would use NDS again and recommend them to anyone looking for a high quality services

    Attic insulation: More than 1000 sq ft

    NDS was very easy to deal with and thorough. We had a mold problem in the attic and after another company did the mold remediation, NDS did a thorough job of taking out the old insulation, fixing all the moisture entries and ventilation, and putting in new insulation. Both the office, and then the crew on site, were easy to deal with. And as this was in connection with a house sale, gave us a detailed report that we could use for the buyers.

    Attic Insulation - NDS Insulation Inc

    NDS Insulation inspected our attic (house is 40 years old). They added blown insulation into the attic. Everyone on the team was very professional, clean, prompt and I noticed a difference immediately. Would highly recommend this service and this company.

    Blown in attic insulation

    This is the second house I have used NDS insulation Inc to have extra insulation blown into my attic. The crew was great, very professional, very friendly and efficient. They explained what was happening and what they did in the attic at the different times in the process. They cleaned up afterwards which most contractors dont do anymore. I would highly recommend them to anyone looking to increase the attic insulation for your house.

    Top notch sevice

    I had an excellent experience with NDS insulation. The sales reps communicated very well, werent pushy, and were respectful of my time. The installation crew was professional, and took the time to explain what they were doing. They cleaned up well after the job was completed. And showed us a video of the final product in the attic. We noticed an immediate improvement in th comfort of our home. Would highly recommend this company.

    Added attic insulation

    The house is noticeably quieter and a very even temperature throughout. The team was very professional and explained what needed to be done. They took videos before discussing what should be done and after the installation was completed.
