Dexperts was founded in 2002 by two lifelong friends, Kevin Olney and Andrew Bleyhl, who both grew up in Oak Harbor and migrated to Bellingham shortly after high school. With extensive prior experience in the construction and home improvement business and a pair of degrees in Building, Construction & Remodel from Bellingham Technical College, the two were operating independent contractor businesses when they joined forces.

“By the end of 2001, I had built many unique projects and gained valuable experience in all phases of residential construction, but there was little consistency to the nature of my work or my paychecks,” Olney says. “Andrew Bleyhl was doing a similar one-man carpenter-for-hire business at the time.  We ended up working together on a few larger projects and found we made a good team. It was time to focus.”

Innovations in materials around the turn of the millennium were also opening up new possibilities. It was a good time to start thinking more seriously about decks as an addition that adds both functional and aesthetic value to a home. “Decks were coming into their own,” Bleyhl says. “For the first time you had many more options than just treated wood or cedar decking. Decks also used all of our skill sets.  You have to pour concrete, install siding, frame the deck. Decking and railing can involve trim carpentry as well, and all of this has to hold up to the outdoor environment.”

By combining their diverse skill sets and focusing on one aspect of the construction and remodeling business, Olney and Bleyhl were able to create a company that both utilized their technical prowess and satisfied their creative needs. They appreciate the aesthetic nature of building decks, fencing, and other types of outdoor improvements, and found a mutual interest in creating decks and other structures such as cedar fences that are pleasing to the eye while remaining functional and durable in true northwest fashion.

“We enjoy building decks and other outdoor structures because they provide a chance for our customers to come up with creative designs in a very functional product,” Olney says. “Deck projects vary widely in size and complexity.  What many homeowners might think is a simple weekend do-it-yourself project can actually involve a lengthy permitting process, hard digging and excavation, lifting heavy timbers and detailed weatherization knowledge.  We can guide them through the process and usually complete the work in a fraction of the time it would take them to complete it alone, allowing the customer time to actually enjoy the product.”

The Dexperts had found their niche in Northwest Washington.

Kevin Olney got his start in construction when he joined his father installing cabinets as a teenager in Oak Harbor. Following high school, Kevin migrated to Bellingham, where he worked for a general contractor during the summer and in a cabinet shop during the winter. By 1998, Kevin had earned an Associate Applied Sciences in Building, Construction & Remodel from Bellingham Technical College, and in 1999, he founded the Evergreen Building Company.  Without a defined business model, he took on all sorts of work from roofing and siding to bathroom remodels to pouring concrete slabs and foundations, and even worked on replica 19th century railroad cars performing detailed trim carpentry before joining forces with Andrew Bleyhl to start Dexperts in 2002.
