Our Story

Four Decades of Delivering Quality Craftsmanship

Dewson is defined by our superior craftsmanship, attention to detail and customer service. We work side by side with our clients, advising on every project phase from architectural design to kitchen faucet selections and incorporate old world craftsmanship as well as modern resources which enable us to produce a home of unparalleled quality.

Our Goal is to Provide a Truly Custom Product Within Your Timeline & Budget

We pride ourselves on our reputation for our quality workmanship and timely construction within budget. We believe when details are efficiently managed, excellence ensues. Dewson’s revered reputation is also attributable to the best internal crafts force in the country. Our own master craftsmen love what they do and their love is very evident in the fine woodwork that they produce. Their quality of work, loyalty to Dewson and team attitude are what inspires us and is a big part of who Dewson is. Fine craftsmen like this are a rare breed today.

We Believe Building Your Home is a Personal Journey

Your home is where you will raise your family, make their memories and spend their precious time. During the duration of our projects, our clients become like family, and we are proud to say that our best testimonials come from prior clients who return to us time and again for additional projects and/or refer us to their friends and families.

Your patience and thoughtfulness assured that the final plans reflected our dreams.

After 8 months in our new home, our excitement continues unabated. Not a day goes by that one of us doesn’t comment on how much we love the house. Your company’s commitment to excellence carried throughout the design and construction phases. We greatly appreciate your generous commitment of time meeting with us and the architect to develop and refine the design. You made us feel like your only clients. We often wondered how you had time for others!

Our Relationships are Our Key to Success

While Dewson is a superior builder, we also focus on maximizing our client’s precious resource of money. Our long and established vendor and subcontractor relationships create buying power and enable us to be very competitive in the bidding process. Additionally, by using the latest technology both in the field and in the office to manage the budgeting, planning and building phases as efficiently as possible, we create better communication for the client and better process management for all. 

Our Leadership Team

Tim Dewson and John McMahon are entering their 4th decade of building beautiful homes. Tim and John’s partnership at Dewson Construction Company, based in Wilmington, Delaware began in 1993, after seeing the need for a hands on, relationship driven approach to building and renovating custom homes. Our focus on our client, their dreams and desires is what has fueled our success in becoming the area’s premier custom home builder, home renovator and general contractor.

With Dewson’s strong client relationships, uncompromising quality, old world craftsmanship and eye on value, we are the obvious choice to help you build or renovate your dream home. We are proud to say that we consistently exceed the expectations of each of our clients. Dewson Construction Company’s portfolio includes stately manor homes and estates in southeastern Pennsylvania and Delaware, along with classically styled coastal homes in Rehoboth Beach, Bethany Beach and Lewes Delaware, Stone Harbor and Avalon in New Jersey and the Eastern Shore of Maryland.
