Customer Testimonials

Dear National Contractors,
I'd like to thank you for your great customer
service for the repair of my floor hump. Thank you very much for your hard work and coordination. Your positive attitude is infectious. You are a joy to work with. 
I'd also like to express my appreciation for Pawel. He respected my home, used protective drop cloth and implemented measures to minimize the dust. He took pride in the quality of his work and gave his best effort even when no one was watching. He is professional, courteous, and an absolute delight to work with. Please share my feedback with him. 
Melanie is very responsive and instrumental in making sure the repairs got scheduled. 

I wish you continued success at what you do! I will have no reservation to continue recommending National Contractors for any future work in our community.
You are the best!

As chairperson of our FSR Maintenance Committee I am pleased to acknowledge that National has completed the fifth year of our roofing project with the same level of professionalism and attention to detail that we have come to expect as was experienced over the past four years.  
I have been involved with the FSR's roofing project for the past three years, where I have closely interfaced with Mario, and along with Jerry provided oversight as the project progressed. Mario's performance continues to be outstanding, providing excellent leadership to his team who are very diligent in their work while keeping the community neat and safe.  The quality and workmanship of the roofs, stucco replacements, stone replacements and gutters continues to meet our high expectations. In addition, Mario interfaces with residents in a very positive manner and he earns their respect. Overall, as a community we are very pleased.
We thank everyone at National for doing a great job and we look forward to working with National and in particular with Mario next year as we enter our sixth year of our roofing project.

Good afternoon,
I live in Hastings Village in Rutherford, NJ where some of your roofers are working. I don’t know anything about roofing but they seem very organized as well as skilled. Another thing I just wanted to let you know because it adds to their professional image, they have been very courteous, respectful, helpful and understanding when I needed to leave and return to my apartment while they were working. They also do a great job at cleaning up before they leave every day. 
With Appreciation,

Heidi, Homeowner, December 2024

On behalf of the Windy Bush homeowners we want to acknowledge toall that we were very pleased with your entire crew. They were very hardworking and respectful of our property. 
We understand the work ethic of the crew and quality of the final product, in large part, is a reflection of the project supervisor. Marek is the type of leader we always hope for on a project. He treated our properties, as I am sure, he treats his own. He always put the customer first. 
Marek, the Windy Bush Board and all of its homeowners thanks you.

National Contractors is a great company to work with for any large project your community may need. Their quality of work is excellent. Their crew is efficient and respectful of the residents who live in these communities. I've been a community manager for 10 years and the thing that stands out above all else is their customer service. They are professional and responsive to homeowners, Board Members, and management from beginning to end of any project They stand by their work and will make it right if there is a problem. They recently completed a large siding replacement project. They were met with so many challenges during the 9 months they worked on the project and never missed a beat. They exceeded everyone’s expectations.
I was very impressed. I strongly recommend National Contractors and look forward to working with them again.

Kim W., Community Manager, March 2023
