Building Beautiful Homes in Northern Whatcom County

JTM Custom Builders is a family-owned construction company established in 2001, proudly serving Northern Whatcom County and the surrounding communities. From custom homes to thoughtful remodels, we are committed to quality craftsmanship, clear communication, and building homes our clients are proud to call their own.

Founded by Jeff Mulryan at the age of 27, JTM was built on years of hands-on experience and a deep appreciation for the trade. After spending more than a decade developing his skills as a lead carpenter, Jeff gained a well-rounded understanding of every phase of construction — from groundwork and framing to final finishes and turnkey completion. That foundation continues to shape the care and precision that goes into every JTM project today.

As a locally rooted business, we believe building in this community means more than completing projects — it means building real relationships. Many of our clients become neighbors, friends, and trusted partners, and we’re proud to work in the same places we call home. Being a local builder means more than working here — it means being part of the community. We’re grateful for the trust our clients place in us, and we’re proud that JTM continues to grow through word of mouth and lasting relationships.

At JTM Custom Builders, we know a home is more than just a structure — it’s where families grow, memories are made, and everyday life happens. Whether you’re starting fresh with a custom home or updating a space that already means a lot to you, our goal is to create something that feels personal, lasting, and truly yours.

If you value craftsmanship, professionalism, and working with a builder who genuinely cares about the people behind each project, you’ll feel right at home with JTM Custom Builders. We would love to build you your next dream home - and thank you for following along!
