About Us

About NSS Exteriors

When it comes to skylights, metal roofing and industrial windows, my company is committed doing it better, down to the very last detail. I’ve been working with these products for a lifetime. Now I want to work with you to create a home or business improvement that you can be proud of.
I'm Paul Mitoraj

The “j” is silent. I’ve lived in the Chicago area my entire life, and I’ve worked with metal for most of it. At the age of 19, I took a job with the Nelson family, working with architectural sheet metal.

I started by sweeping the floors, did the work, absorbed the mentoring for 20 years, and in 2010 I bought the company.

This company has been in existence, in Chicago, since 1931. With 8 brothers and sisters of my own, my wife and I have 4 kids; our family is all in the Chicago area. We’re not going anywhere, and will be here here for you for years to come.

I’m a stickler.

Come visit our shop and the first person you’ll meet as you enter the door will be me. I sit in the reception area, because I’m picky. I want to know about everything that’s going on in my business.

We are lucky enough to have a big shop with great equipment. Drop in any day, and you’ll find it clean, freshly painted and in 100% working order. Nothing drives me nuts more than something not working, or not being where it’s supposed to be.

When we work on your home or business, the same attitude carries over. We know that you’re worried about what we’re going to do in, on and around your house or company. So, we start by covering our shoes, and sticking to our motto of “leave it cleaner than you found it”.
I can’t lie.

Whether it’s my childhood of Catholic schools and a military dad or just good sense, I can’t lie, and neither can our salesman, Jeremiah Meek. Everyone in our organization is committed to doing things right, down to the last detail.

We’re not pushy. We know that you don’t have to buy a skylight or roof from us, or that now might not be the right time. We can give you a presentation, but we’re not going to lie.

I’m not the only employee.

I employ great people that care about what they do.

Our installation teams are our own employees. We will never hire outside contractors, because I want to be in control of everything that’s happening in my business, and on your job site.

We work together year-round. When we’re not working on a job site, we’re working in the shop to prepare for the next season, training, and of course, keeping everything in working order and in it’s place.
