    Attic insulation: More than 1000 sq ft

    Smooth project from initial inspection to installation. Team was punctual and professional and delivered scope of work as per the estimate. Hopefully the coming winter months will prove this to be a good investment.

    Attic insulation: 500 - 1000 sq ft

    Highly recommend these guys! Nick and Chris did an amazing job with our attic insulation. They were super friendly, polite, and careful around the house. They cleaned everything up afterwards and honestly left the place cleaner than before they came. Really happy I went with them.

    Attic insulation: More than 1000 sq ft

    The job was effciently quoted with the invoice detailing all the work that would be done. The team was dilligent and polite and cleaned up after each visit superbly. After each step Sady explained what was done, showed me video and photos of the work done and explained the next step. I am very satisfied with the work done and the way I was treated each step of the way.

    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.
