## The honest read

603-Carpenters LLC describes itself on its website as a family-owned carpentry business based in Derry, New Hampshire, and says it has been in business for 27 years. Its site lists a service area that includes Derry, Hillsborough, Merrimack, Amherst, Manchester, Bedford, Milford and Hollis, among other towns.

A recent Google reviewer says Mike installed a slider for them about 6 years ago and that the new door was well insulated, which became very clear the next winter. That reviewer then hired him to gut and refinish a basement, which turned out beautiful, and has since hired Mike for many other jobs.

In another recent Google review, a customer says Mike came in after another contractor never completed a kitchen remodel, completed the work quickly, and that the finished work was exceptional.

**Strengths:**
- Kitchen remodel completion — finished quickly after another contractor never completed the job
- Basement refinishing — gutted and refinished a basement that turned out beautiful
- Slider door install — new door's insulation became clear the next winter
