About Ontario Builders

OUR STORY

Built on Craftsmanship, Driven by Integrity

Ontario Builders is a fully insured general contractor and home improvement company based in Mexico, NY, founded by Stephen Bolster in 2022 to bring quality craftsmanship and honest pricing to homeowners throughout Central New York. What began as a vision to do things the right way — showing up on time, communicating clearly, and delivering work that lasts — has grown into one of Oswego County's most trusted contracting companies.

Stephen started Ontario Builders because he saw too many homeowners getting overcharged, underserved, or left with unfinished projects by contractors who made big promises and disappeared. He made a commitment from day one: every client would receive a fair, transparent quote with no hidden fees, and every project would be completed to the highest standard of workmanship. That commitment to fair pricing is not just a business policy — it is the foundation Ontario Builders was built on.

What sets Ontario Builders apart is the ability to handle all phases of residential construction under one roof. Whether you need a small handyman repair, a complete kitchen remodel, a full roof replacement, or a large-scale room addition, Ontario Builders has the experience and the crew to get it done right. From foundation work to the finishing touches, you deal with one contractor, one team, and one point of accountability throughout the entire project.

Ontario Builders is fully insured, carrying both general liability and workers' compensation coverage on every job site. This is not just a checkbox — it is a promise that your home and your family are protected while we work. Stephen takes insurance and safety seriously because he treats every client's home the way he would treat his own.

As a proud member of the Mexico, NY community, Stephen and his team take real pride in serving their neighbors. Ontario Builders operates within a 50-mile radius of Mexico, covering homeowners across Oswego County, Onondaga County, Jefferson County, and the broader Central New York region. Whether you are in Fulton, Pulaski, Syracuse, Watertown, or any of the smaller towns and villages in between, Ontario Builders is ready to help with your next project.

Since opening its doors in 2022, Ontario Builders has experienced rapid growth built entirely on word-of-mouth referrals and repeat business. With over 200 completed projects and a 4.9-star rating, the reputation speaks for itself. Homeowners trust Ontario Builders because the quality of work is consistent, the pricing is honest, and the communication never stops from the first phone call to the final walkthrough. Ontario Builders is also a BBB-accredited business and maintains an active presence on Yelp, giving homeowners even more confidence in choosing the right contractor.
