Electrician in Waltham, MA
From triple-deckers to Moody Street storefronts and converted mill space, Waltham runs on the kind of wiring Sartell does every day.
Serving Waltham
Your Local Waltham Electrical Contractor
The Watch City mixes dense residential streets and multi-families with a busy Moody Street business district and old Charles River mills now converted to offices, labs, and lofts. That means older homes needing service and panel upgrades in one part of town, and businesses needing three-phase power, lighting, and clean tenant fit-outs in another. Sartell handles the whole range, upgrading residential services, rewiring safely, and wiring commercial space to code and on schedule.
We coordinate around your household or your business hours, pull the permits, and leave every job site clean.
