Built as a family

Coltwood Construction LLC is built on craftsmanship, integrity, and doing the job right the first time. We specialize in high quality residential and light commercial construction, with a strong foundation in framing, structural work, and full scope remodels. From kitchens and bathrooms to additions, decks, concrete, ADUs, structural upgrades and ADA compliance upgrades, we approach every project with precision, care, and a deep respect for the homes and spaces we work in.

What sets us apart is not just how we build, but how we work with people. We believe great projects start with clear communication, integrity, honest expectations, and detailed planning. Our clients can expect transparency, professionalism, and workmanship that meets or exceeds code, because we build everything as if it were our own.

At Coltwood, construction is more than a trade, it's a craft. Every project is treated with the same level of pride and attention to detail, ensuring results that are safe, durable, and built to last.

Meet the Family

A family trade built by father and sons.

Jason Coulter Sr.

I’ve spent more than 29 years in the construction industry, starting where it matters most, boots on the ground. Over the years, that hands on foundation grew into managing and delivering multi million dollar projects. Along the way, my two sons developed the same passion for the trade and followed a similar path. Together, we’ve learned that strong planning, clear communication, and true accountability are essential, because great results never happen by accident.

Today, we bring that same discipline and professionalism to residential construction. Whether we’re opening up a kitchen, rebuilding a shower, reinforcing a structure, or installing a new driveway, every project is approached with one simple philosophy: do it once, and do it right. We believe your home deserves the same level of care and precision as any large commercial build.

For me, this work is personal. Making your dreams turn into a reality not just building spaces, we are helping people shape the place where they live their lives. Whether its starting off fresh or beginning a new chapter in their lives, for me it means showing up, communicating clearly, respecting your home, and standing behind our work long after the tools are put away.

Dylan Underwood

I am a construction professional with over a decade of hands on experience in the building industry, with a strong specialization in framing and structural work. Throughout my career, I’ve contributed to a wide range of projects including concrete, decks, fencing, excavation, septic systems, and both residential and commercial remodels. This broad background gives me a true ground up understanding of construction, allowing me to approach every project with precision, efficiency, and a focus on long term durability.

Beyond the tools and technical skillset, I take pride in being personable and easy to work with. I communicate clearly, listen carefully to my clients’ goals, and bring extensive experience in writing detailed, accurate bids. I believe trust, transparency, and accountability are just as important as the finished product.

I genuinely love what I do, and it shows in my work. Every project is treated with care, attention to detail, and a commitment to building things the right way, safely, to code, and built to last.

Jason Coulter Jr.

I have been in the construction industry for five years, starting at the ground level sweeping jobsites and learning how a project truly comes together. That foundation grew into hands on experience framing and building additions on multi million dollar homes. My core expertise is in tile work, framing, and structural upgrades, from slab to walls to rough in. I have seen what a well run jobsite looks like, and I have seen what inefficiency costs. Those experiences shaped how I work and how we operate as a company.

Together, our team brings a combined forty three years of construction experience. Each of us carries our own techniques and strengths, allowing us to complete work efficiently, on schedule, and most importantly, safely. That balance of experience is what sets us apart.

My role extends beyond the field. I am involved in both production and operations, including photography, videography, website management, and lead development. This gives us a complete in house system from first contact to final walkthrough.

Our goal is simple: to make your life easier. You should never have to wonder what is happening next on your project. Through clear and precise communication, you will always be informed, confident, and supported from start to finish.
