## The honest read

Mast Hill Remodeling is a kitchen, bath, and general remodeling business based in East Weymouth, MA, run by owner Charles Seppala, whose BuildZoom profile credits him with nearly a decade in the trade.

Public building-permit records give a clear look at the kind of work the company takes on. A 2017 permit shows the company removing a load-bearing wall and installing structural beams alongside new kitchen cabinets and a new primary bedroom shower — real structural and finish carpentry in the same job. More broadly, permit records show the business has pulled 34 building permits over the years, with most of that work concentrated in Hingham, MA.

Because most of the documented project history is in Hingham rather than its own East Weymouth base, it's worth confirming the company actively serves your specific town before booking, along with a current project timeline.

Mast Hill Remodeling is worth considering for a kitchen or bathroom remodel that involves real structural changes — just confirm service area, licensing details, and scheduling directly with the owner.

**Strengths:**
- Structural capability — a 2017 permit shows load-bearing wall and beam work
- Established permit history — public records show 34 building permits over the years
- Kitchen and bath work — a 2017 permit lists new cabinets and a shower

**Concerns:**
- Service area — most recorded permits are in Hingham, not East Weymouth

**Where sources disagree:**
- Federal loan records list the business as Mast Hill Remodeling LLC, while its BuildZoom profile describes it as a DBA operated directly by owner Charles Seppala — the two describe slightly different legal setups for the same business.
