Frequently asked questions

Do you offer free estimates for custom carpentry work?

Yes. We visit your home in Cape Cod, 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.

How long does a built-in take?

It depends on the size of the piece. We build it in our shop first, so the time we spend in your home is mostly installation and finish work, and we give you the schedule with the estimate.

Can you match the woodwork already in my house?

Yes. We measure the existing trim and profiles and build the new pieces to match, so the built-in looks like it was always part of the house.
