The Diamond Difference

With over 100 years of combined finishing experience, the Diamond Prefinish team takes pride in their craft. Everything is done in the shop by hand, from prepping and spraying to thorough quality assurance checks. The human element of our process allows us to provide custom solutions while being meticulously detailed, so we always provide a consistent, quality finish.

Diamond Prefinish Team

Our Team

At Diamond, we not only care for our customers, we care for our employees and that impacts how work gets done. Our team takes a strong sense of pride in their work and are dedicated to paying close attention to the details from start to finish.


Our Process

Diamond’s commitment to quality means we take our process very seriously.  Each step is designed to ensure you receive the best finishes every time.

Custom Color Matching

Diamond Prefinish’s in house custom stain matching service gives us the freedom to offer a much faster turnaround time, allowing us to provide a consistent high-quality finish that can always be replicated. Every project receives a job-specific color code, which we call a DP number so that if you ever need to touchup your project or complete a different project with the same color, it can easily be done.


The key to a strong finish starts with preparation.  Depending on your project it will go through several stages of detailed preparation, from cleaning to sanding to masking.


Our specialized facility is equipped with spray booths designed to achieve quality results.  At Diamond, your project will go through several stages of finishing including priming, painting, staining, and/or clear coating.

Quality Assurance

We pride ourselves on our quality of work, and all projects undergo rigorous quality assurance (QA) checks prior to being considered complete.  If we find something that needs to be refined, it will be resolved and rechecked by a supervisor before the job is finalized. Once your project has successfully passed our QA inspection, you will be contacted to schedule pick up.

Our Shop

We take pride in our clean, organized shop, where each team member understands the impact they have on making your project a success.  Our facility and team are trained to ensure quality at every step.

Our spray booths allow us to use almost any type of finish: fire-retardant treatments, primers, paints, stains, lacquer, varnishes, and polyurethanes.

Finish Strong

From our talented employees to the layout of our booths and cleanliness of our shop, at Diamond Prefinish every decision we make shows we care for our customers by providing quality, custom finishes, on time, every time. We are dedicated to consistently delivering industry-leading finishes with competitive job turnaround times, and always finishing strong.

“After using several other finishers in the past, I was finding myself having to settle for sub-par work much too often. But since I’ve been using Diamond, I see myself looking no further. All of my projects go there now. they are professional, knowledgeable, flexible and courteous. they are easy to work with, competitively priced and produce a finished product as good as any I’ve seen. i have referred them to others with happy results and will continue to do so with great pleasure.”
