Mullen Building & Remodeling is a family-run Cape Cod custom home builder and remodeler based in Osterville, founded by Doug Mullen in 2003 and self-reported at 23 years in business. Its Massachusetts home improvement contractor registration is verified active, and on Google the firm holds a 5-star average from 22 ratings. The written record, running from 2016 through 2026, is dense with specific, large-scope projects rather than routine fixes. One client describes a two-year project starting in 2022 that included demolishing an existing structure, preparing the site, and building a new mid-century home with an ADU on the mid-Cape, praising Mullen's daily and weekly progress emails and its working relationships with subcontractors and the town. Another describes a rebuild after a major house fire that required integrating steel into the surviving structure — handled, the reviewer says, without bringing in outside contractors beyond a structural engineer, and finished on time and on budget. A third recounts taking down an 1800s barn and repurposing its materials into a home addition, with the foreman on site daily and no surprises on cost or schedule. Several reviewers named a specific project manager — Katie, in a 2022 review — as a strong communicator who kept a remodel on budget during a period when materials were hard to source. Multiple clients describe hiring Mullen more than once, including one relationship a 2022 review says has run more than 30 years. Two Houzz reviews from 2016 and 2017 describe earlier remodeling and general-contracting work, both positive; they extend the written record further back rather than leaving a gap in it. BuildZoom's permit records credit the firm with 46 permitted projects and a score it says places Mullen above 88% of the Massachusetts contractors it tracks; that page also lists an earlier Massachusetts home improvement contractor registration, #138368, as inactive and at one point cancelled — a different number from the current, active one. Anyone considering Mullen for a large project should ask which of the past big builds — the fire rebuild, the ADU-and-new-home project, the barn conversion — is closest to their own scope, since that's where the written record is strongest.
“Tucked away at the end of a long, winding driveway on Cape Cod, a once neglected property finds new life as a newly-built mid-century modern home under the expertise of Mullen Building.”
We’ve worked with the team at Mullen on multiple projects at our home in Mashpee — from smaller jobs to larger renovations — and they’ve impressed us every time. The quality of their work is always outstanding, but what really sets them apart is how easy they make the entire process from planning to project completion. We wouldn’t hesitate to hire them again and highly recommend them to anyone looking for a contractor they can rely on.
If I could give Mullen Building more than five stars, I would. When we first hired Mullen Building to renovate our home, we had a vision of what our dream home could be. Their team not only brought that vision to life but they exceeded every expectation we had. From start to finish, their professionalism, craftsmanship, attention to detail, and commitment to excellence were evident in every aspect of the project. What truly sets Mullen apart is that they stand behind their work. Even after the project was completed, they were responsive, reliable, and always willing to address any questions or concerns. That level of integrity and customer service is rare and speaks volumes about who they are as a company. In fact, we were so impressed with our renovation that when it came time to add an addition to our home, there was never any question about who we would hire. Mullen was the only contractor we considered—and once again, they absolutely knocked it out of the park. The addition seamlessly blends with the original home, and the quality of the work is outstanding. We are now on project number three with them and at this point, we joke that we're either going to run out of projects or run out of money! They've earned our complete trust and confidence. We're even considering putting a plaque on our house that simply says "MB" because their work has become such a meaningful part of our home. If you're looking for a contractor who delivers exceptional results, takes pride in their craftsmanship, and truly cares about their customers, look no further than Mullen Building. We couldn't recommend them more highly.
We had an absolutely wonderful experience with everyone at Mullen from start to finish. Doug and his team provide exceptional quality in their work, as well as everyone who they bring into the project. We took down an 1800s barn, saved much of the materials and repurposed them in an addition to our home. Corey, our foreman, was on site daily not just to supervise but hands on. There were no surprises on timing or cost, which after doing many renovations in CT and MA was a first. An added bonus is that we enjoyed being around these people, which is not always the case. Highly recommend!
Doug and Team are fantastic to work with. They are professional and strong communicators. I've worked with them on several projects and now have the pleasure of having them work on my own home.
Mullen Building has gone above and beyond with our build in Yarmouth. Teamwork was key as I was offsite for most of the build. From start to finish the entire team was professional, efficient and the build site was always neat and clean (inside and out) including their trucks and equipment. Their team was always friendly to neighbors and conscious to the temporary effect on the neighborhood. It's evident they take pride in their work and its reflection on the Mullen name. It has been a pleasure working with them. I hightly recommend Mullen Building and Remodeling.
