From start to finish, NDS quoted and completed the job in 2 weeks. Very satisfied with the quality of work and communication from the staff. Very seamless from start to finish.

Im very happy about this service and they are expert.they cleaned everywhere, when they fi

Luca who gave us the estimate and the 2 men who did the actual work were very friendly and very professional. They cleaned up after they were finished as if nothing had happened. The whole job was completed in approximately 2 hours. You could feel the difference as soon as they were finished. I will easily recommend them.

Very professional company - explained everything and cleaned up like it was new. Recommend for anyone looking for blow in insulation!

The experience with NDS was great. They responded quickly to a request for quote. The technicians kept me up to date the day of, of their arrival time. Moreover, they took the time to explain the intricacies of roof maintenance. They cleaned up after they were complete and were overall pleasant to work with.

They did what they said they were going to do, all is good, added baffles were needed. Attic only had 4-6 inches now has approximately 24 inches which now gives a R60 value instead of R20 value. Job was well done. Yes I would recommend NDS.

Martha from the office gave the quote. She was friendly to talk to and responded promptly by phone and email. We were impressed by the service received by the three young men who were at our home Saadi, Abbas and Alex. Their teamwork was extraordinary. Hardworking, respectful, and senior friendly. They showed up with two trucks. Saadi explained everything in detail along with pictures as the work progressed. All three were eager to help or explain. Canvas mats were laid down on the floors and stairs and the cleanup was spotless. We chose NDS because of the great reviews and their reputation. They have our endorsement!

Very courteous, prompt and knowledgeable. Very impressed on the way they worked to insulate the attic with no mess whatsoever. All workers had the diplomacy to work for someone (homeowner) with ease. I would recommend this company for all future work to have done. Happy homeowner
