Customer Testimonials


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

I want to thank you for your professionals who have been working with us again this year.

The quality and workmanship of the finished work of our new roofs, stucco replacements, stone replacements and gutters certainly has again met our high expectations.  We appreciate the diligence of all your workers in keeping our community clean, neat and safe during the work.  It is obvious to us that everyone from your own staff and your subcontractors are talented and accomplished professionals in every aspect of the work they do.

The overall supervision that Mario has provided during this year's portion of the project continued to be outstanding.  Mario goes over and above expectations as the job supervisor.  We have received kudos from residents that have been assisted by him i.e., "Mario is amazing! So professional and thorough, Truly top shelf".   We continue to hope and will be most appreciative to be able to work again with Mario during our next phases of this project.

Thank you all for doing such a great job on our behalf and we look forward to working with you again in next year’s phase.

Hi!  I just had the roof of my townhouse replaced and also the gutters. I wanted you to know that Mario's team of roofers did a great job! They were extremely professional, took safety precautions for homeowners & (wore masks when speaking with homeowners!). They were punctual, consistent, and meticulous. They did a fantastic job!  Mario answered all my questions. Very pleased with the results.
Thank you!

National Contractors,
I wanted to send a personal note to compliment National on the work product being performed at Lamplighter Village.
Each time I return to our property I am proud of the look of the buildings completed and in the small hand I had in making it happen. It was a long and arduous process to get here but the results more than warrant the efforts.
Thank you for your continued efforts on our behalf.  

Dennis, Lamplighter Village, May 2022

To Whom It May Concern: I am a resident of Deerfield Condos and a full-time caregiver for my mother of 90 years. Before the beginning of the Deerfield Condos siding project, the property manager sent out an owner letter directing all inquiries concerning the project go solely to him. Because of some history between the manager and myself, I knew that any job inquiries would have to involve another resource to solve my problem(s). Your job supervisor for this siding job, as you know, is Tom Z. After contacting Tom several times, I discovered that the issues were solved in a timely and efficient way. My choice to involve Tom was definitely the proper decision. Tom should be commended for providing an added safety service to the elderly and physically challenged in our community. The affected residents contact Tom for the workers to stop construction during work hours only when that resident exits or enters the front entrance of the buildings. He provides his cell number to those that request his help with a 10-15 minute lead time. This action not only provides a safer environment but greater piece of mind to the residents. Hopefully, the property manager of the community will publicize to the entire Deerfield Condo community that this service is available. Currently, there are 35-40 percent of our residents that are either elderly and/or physically challenged and would welcome this service. I am confident that all would be appreciative. And, I trust that Tom will be recognized for this action. In conclusion, I now know one of the reasons why the sole decision by the Board and Manager in awarding this siding contract to National Contractors was because of services like this. Wishing Tom and your company a Safe and Prosperous New Year.

I want to let you know that we have just had National Contractors finish the replacement of our skylights. They came yesterday when they said they would in the morning and had the job done by early afternoon. I could not be more pleased.
