Frequently asked questions

Do you offer free estimates for finish carpentry?

Yes. We visit your home in Mashpee, MA, take measurements and talk through what you want, then send a written estimate. Call (508) 648-8998 or use the form on this page.

Who does the work?

Our own team, start to finish. We cut, assemble, paint and install everything ourselves, with no subcontractors, so the person who measured your space is part of the crew that installs it.

Do you work on new construction or only remodels?

Both. We work directly with homeowners and with architects and builders on new homes, and we take on single rooms in existing houses.

Do you paint the trim too?

Yes. Painting is part of our in-house process, so the trim is fitted, filled and finished by the same team.
