About Us

Stronger Than Ever

Our family business started in 1986 with just the two of us — Greg, a woodworking craftsman, and Kim, a business manager. We built our reputation restoring historic doors, windows, trim, and cabinetry. We loved the work, and we learned something important early on:

No two openings are ever the same.

Historic homes rarely follow standards. Every door opening was different, and that made restoration beautiful — but also expensive and difficult for homeowners to afford.

In 1999, Greg set out to fix that. He designed a better way: a custom jamb system that could correct irregular openings while preserving original doors. It did not have a name yet, but it solved a major problem.

Making restoration practical, repeatable, and affordable.

We shifted our business to focus on doors and windows, combining standard installations with custom-built solutions for historic homes. Through years of real-world installations and five design iterations, that system became what is known as StrongJamb.

In 2015, we incorporated as ProSpeed Security Door Jamb Systems, Inc. Our son Joseph became an integral part of the business, and we brought StrongJamb to the Dayton, Ohio market.

We kept working through COVID, continuing installations and refining what we built. In 2021, our family faced serious challenges, but we did not give up. During that time, Greg and Joe developed something new: the Armor Plate.

A faster, simpler way to reinforce the weakest point in modern door frames. Best of all, the Armor Plate maintains the aesthetics of the StrongJamb Full Frame while allowing more adjustment and superior security for an aftermarket security plate.

That became the StrongJamb Armor Plate — now patented, and ready for today's residential and multifamily markets.

Prospeed professionally handled the procurement of a sliding door and 2 sliding windows for my Centerville condo (I am an out-of-town owner) and installed them with me on site. Joe Pollard and his crew performed the work and left the condo in good shape. Greg Pollard made sure I was satisfied. I recommend Prospeed for door and window replacement.
