About Us

We founded this company as a window, siding and door contracting company on the firm commitment of providing Kansas City with the very best fiberglass window and James Hardie Fiber Cement Siding products, installation service, and craftsmanship possible.

We opened up shop facing the sad truth that the home contracting services industry is full of companies offering low-quality products at inappropriately high markups, and who use install crews that pay far less care and attention to craftsmanship detail than they should. We wanted no part of that!

We wanted to do better by our customers than the rest of the industry. When we opened up StateLine Exteriors (formerly Fiberglass Windowshop & Exteriors), we did so with the expressed mission to provide the Greater Kansas City Area homeowners with the very best window, siding and door products possible, and with the highest caliber of construction craftsmanship and attention to detail.

With more than 20 years in the window, siding and door industry, our team is veterans of virtually every role to be held in the industry. This depth of knowledge is what gives them the ability to confidently design the right solution every time, and our customers the comfort of knowing that our experienced hands will get the job done correctly every time.

Our sales approach is designed to be a consultative, low-pressure experience. We take pride in educating our customers. Each new opportunity starts out with a mutually educational consultation where customers get to learn about the products we offer, and we get to learn about them and their home. Working together, we design a home transformation plan and personally explain all its aspects.

Excellence in knowledge and technical skill are essential; they are the cornerstones of any service contractor’s business. While we have both in spades, there was still one other critical piece of the puzzle that we had to solve: the materials. No matter how excellent the craftsmanship might be if a poor quality material is used it’s just not possible to achieve great results. The hunt was on for us to find the best window and siding manufacturer.

We chose to partner with FiberFrame and Vinylmax Windows, and with James Hardie Siding after an exhaustive product search. As manufacturers, they caught our attention because of their shared value and emphasis on excellence. Their products clearly stood miles ahead of other window and siding products.

We know that best product with the best installation provides a winning combination every time, and this is what we need to be able to confidently deliver on our mission to provide Kansas City with the very best window, siding, door products, installation, and craftsmanship possible.
