Construction Company | DeWitt Construction

John came out for a quote the day we first spoke. Once materials were delivered, the job was done in a day! Best quote of three different contractors. Will use again and recommend to others!

John was outstanding. Was able to speak with him personally each time I called. Very responsive and answered all questions and concerns. Work was done on time and looks beautiful.

John and Richard is amazing at fixing up my house. They fixed a hole in the roof made by falling ice from a higher roof. Patched up the chimney on the roof, and pour cement for a new porch. My dad is very happy with the result.

Dewitt Construction responded quickly to my call after sustaining a leaky roof. Within hours, patch work was complete to temporarily repair the roof. In just a few days the roof was completely repaired and all requested interior improvements were complete opening up our entryway and creating a warm and welcoming space. All of the employees were respectful, courteous and understanding of our needs as they operated within our home. They worked quickly and efficiently throughout the entire project. I will definatly be doing business with them again.

Got a nice metal roof from Dewitt Construction. They were on time, friendly, did great work, and cleaned up well. They priced the roof competitively, and are a great company to use. 10/10 would recommend.

John came to my house the day I requested an estimate, which was thousands less than another quote I’d received. Within 2 weeks John & his crew were at my house and completely installed my metal roof in 1 day! They did a great job!!

Had a leak in roof,John was here with in hr with quote, rebuilt12 ft of roof eves,and installed metal roof over 3 section of roof ,his crew were professional, and I would recommend.

Very fast service! Called and then less than two weeks later the job is all done!

I needed roofing and plumbing work done and had left messages for several businesses for both, but none returned my calls. John Dewitt was recommended by the employees at OD Greene. Not only did he answer his phone when I called, but came over the same day to see what I needed. John and his crew were great! Work was done quickly and professionally, and I wouldn't hesitate to call again if the need arises.

Where do I begin? John DeWitt is a godsend! Answers his calls, personally, unless he’s up a ladder; returns calls; arrives as promised; has a great crew; estimates are fair and true. Not to mention John is an overall good guy! Professional and efficient. Thank you so much.

DeWitt Construction LLC works with homeowners across Northern and Central New York who need more than piecemeal repairs. Whether you're planning a new build, updating your kitchen, or preparing a rural site, you'll work with a contractor who understands the scope and can see it through. Regional building challenges and weather patterns shape how every project is approached.

You'll know what to expect at each stage. Timelines, material choices, and site logistics are discussed upfront so there's no guesswork. Your property's layout, access, and conditions inform the plan, and adjustments are made when they're needed.

DeWitt Construction LLC delivers workmanship that holds up over time because decisions are made with long-term function in mind. You're not left coordinating multiple trades or managing conflicting schedules—the project stays in one set of hands from start to finish.

Request an estimate to begin planning your next residential project.

When you hire a contractor who handles multiple phases, you're eliminating the gaps that slow projects down. Instead of scheduling separate crews for framing, electrical, finishes, and plumbing everything flows in sequence under one point of contact. Expectations are set early, and each phase is documented so you understand what's happening and why.

Site preparation, structural work, and finish details are coordinated as part of a single timeline. Changes are handled without passing responsibility between trades, and your input is folded into decisions as they come up.

That approach applies whether you're building an addition, replacing a roof, installing a septic system, or finishing a basement. Here's what full-service management includes:

DeWitt Construction LLC brings years of hands-on work to properties throughout Jefferson, Lewis, Oswego, and Adams. That experience shows up in how site conditions are read, how materials are chosen, and how unexpected issues are resolved without delay. Rural lots, older homes, and new construction all require different approaches, and familiarity with the region makes those decisions more straightforward.

Quality workmanship means more than clean lines and sturdy framing—it means the work is done right the first time, with accountability at every stage. You're not chasing down answers or waiting for crews to show up. The focus stays on delivering a finished project that matches what was discussed and performs the way it should for years to come.
