## The honest read

SED Associates Corp. is a Norwood engineering firm whose Procore profile lists fire suppression, HVAC, and plumbing among its services and shows 111 total projects, including 40 active. The profile gives an address at 89 Access Rd Unit #12 and a Massachusetts phone number.

Its public project mentions place the company in MEP or mechanical engineering roles on Boston-area work, including the ICA/Boston Watershed and 15 Winter Street. Those mentions identify specific professional roles, but they do not include homeowner reviews or a customer-rating history.

The Procore profile is the clearest place to confirm the current service mix, project activity, and contact details before calling. Ask which plumbing or HVAC scope the firm handles directly and whether its current project experience matches your residential needs.

**Strengths:**
- Project volume — Procore reports 111 total projects and 40 active
- MEP engineering — credited on Boston-area institutional projects

**Concerns:**
- Residential fit — confirm the firm's experience with your specific home scope
