Joshua started in vinyl siding installation in 1998, at 15 years old. Within six months he was running his own crew. By 18 he had launched All Season Siding and Windows, his first company — and it became a recognized name in the Kansas City market. At a time before digital marketing existed, he ran phone book ads, put out door knockers, planted yard signs, and built the kind of reputation where he was “that guy someone knows.”

He was also ahead of his time in one specific way. While other contractors were quoting jobs and waiting for checks, Joshua was working with multiple financing brokers to offer clients payment options on the spot — building that into his sales process before most contractors had a sales process at all. It is a dynamic he has never forgotten, and it is part of what drives his thinking about contractor technology today.

The early years also brought every hard lesson a young business owner can receive: clients who didn’t pay, equipment theft, bad partnerships, and setbacks that end most people’s careers before they’ve really started. He kept going. When he returned to Kansas he took a deliberate detour — programming courses during the day, HVAC certification at night. Not because he planned to leave construction, but because he is the kind of person who needs to understand how systems work.

In 2009, Joshua was brought in to build and lead the window and siding division of Mesler Roofing, Siding and Windowsout of Lawrence, Kansas — a company founded in 1981 with a strong regional reputation in roofing. Over the next seven-plus years, he built the division into an operation that rivaled the company’s founding roofing business: documented processes, replicable crew checklists, and, at peak, up to 40 people across 6 simultaneous crews.

“Mesler is where I began to understand systems and process. I learned to track everything, create checklists, and hold a standard across an entire operation — not just on the jobs I was personally on.”

After leaving Mesler, Joshua wrote a business plan and launched Harden Exteriors DBA Acumen Renovations in September 2017. Today Acumen serves the full Kansas City metro — Kansas City KS, Kansas City MO, and surrounding Johnson County communities — across decks, siding, windows, doors, screen porches, pergolas, and full exterior renovation. The company holds a Johnson County Class A General Contractor license and a Kansas City KS Residential General Contractor license, carries $2 million in general aggregate liability and $1 million in workers’ compensation insurance, and holds an A+ rating with the Better Business Bureau. Acumen has been named a Nextdoor Neighborhood Favorite in 2022, 2023, and 2025.

As a Class A licensed general contractor, Joshua has completed full ground-up residential home builds — raw land to finished house, handling all permitting, subcontractor coordination, and project execution end to end. One project required installing and tying in 600 feet of sewer lineinto the city’s mains — work he negotiated the right to self-perform, saving approximately $40,000 in subcontractor costs. That full-system knowledge — from finish carpentry to foundation systems to sewer infrastructure — informs everything Acumen does.

Every blog post, every service page, every FAQ on AcumenRenovations.com was written by Joshua personally. Not by a marketing agency, not by a content writer, not by an AI tool given a topic and told to produce 1,500 words.

The reason is simple: the details matter. The difference between content that actually helps a homeowner and content that merely fills a page is whether the person writing it has stood in a basement and watched water come through an improperly drained window well, evaluated a cinder block foundation before committing to a window location, or negotiated with a city inspector over 600 feet of sewer line. Joshua has done all of those things. If you’re reading this site, you’re getting the real thing.
