Expert General Contractor in Harwich, Massachusetts
We have worked on enough Harwich exteriors to know what tends to be waiting behind the old material. Housing here runs to cape cod style homes and shingle-style cottages, much of it 30-100+ years old. Add salt-laden air that strips coatings and pits fasteners years earlier than inland weather does, and the details that matter become obvious.

Choosing who does exterior contracting on a Harwich home matters more than choosing the material. Most of what fails early fails at a joint, a flashing lap or a fastener line, and none of those show up in a brochure. Here, the two things we expect to deal with are extreme salt air damage and hurricane and nor'easter vulnerability. Our crews are our own employees. We do not sell the job and hand it to whoever is available, and the person who quoted your project is on site while it runs.
Comprehensive General Contractor Services in Harwich, MA
Concretely, on a Harwich project that means an agreed rate for hidden damage written into the contract before we start; siding, windows and doors sequenced so each is flashed into the next correctly; permits filed and inspections scheduled by us, in the right order against the material lead times. Materials are rated for the New England climate zone, and we account for nor'easters that load a wall with water and wind from the same direction for hours. It is all standard practice. The difference is that it gets done on every elevation, including the one facing the neighbour's fence that nobody inspects.

General Contractor FAQs — Harwich, MA
Common questions from Harwich homeowners about general contractor
How long will exterior contracting take on my Harwich home?
Plan on three weeks on average when several trades are sequenced together. Barnstable County weather does move schedules — nor'easters that load a wall with water and wind from the same direction for hours is the usual reason — so we build a weather margin into the date we give you rather than promising one we cannot hold.
Do you pull the permits, or do I?
We handle it. Filing with Harwich, booking the inspection slots and being there when the inspector arrives are all ours under HIC #204634. You should not be chasing paperwork for work you are paying for.
What usually goes wrong with exterior work on homes in Harwich?
The three we see most often here: two warranties that each point at the other when something leaks; a rebuild that stalls because nobody sequenced the permit against the material lead time; and work that was quoted by three separate trades who each assumed someone else was handling the flashing. Locally, extreme salt air damage comes up repeatedly on cape cod style homes.
Are you actually local to Harwich?
We work out of Charlton, 75 miles away — a planned trip. That matters mostly for the unglamorous parts: getting back out for a warranty call, or being on site when the inspector is.
What parts of Harwich do you cover?
All of it, including South Harwich, East Harwich, Harwich Center and the rest of ZIP 02645. We also work throughout Barnstable County.
Do you use subcontractors?
No — our own people, start to finish. Subcontracting is how a schedule slips and how nobody ends up owning a defect.
