Panel replacement and service entrance

A 200 A upgrade, a new mast or a new service entrance starts with a load calculation. Hydro-Québec does the shutoff and reconnection: we coordinate the work day with the utility and tell you in advance how long the power will be off.

New construction, businesses and apartments

For a new house, a commercial space or an apartment building, we work from your plans and with your contractor, from the service entrance to the final check. In Granby, the town only reviews complete permit applications: have your documents ready before applying.

Here is what the calculation counts, the solutions that sometimes avoid the work, what the 2026 Code changes and how it goes, from the request to the utility to the power coming back on.Read the guide 5 min readUnderground or overhead service entrance: how to choose for a new house or a service to redoThe utility’s cable arrives either through a mast on the roof (overhead) or through a trench (underground). Overhead is simpler to install; underground is invisible and safe from branches, but needs a trench, conduits and close coordination. The choice depends on the lot, what the utility offers on your street and your priorities.Read the guide 6 min readThe load calculation: is your 100 A enough before you buy an EV charger, a heat pump or a hot tub?The load calculation adds up what your house draws from the grid, following the Code. It tells you whether your 100 A service is enough, or whether you need a sub-panel, load management or a 200 A upgrade. It’s done before adding an EV charger, a heat pump or a hot tub, never after.Read the guide

« Super service de William. Il répond rapidement aux demandes et prend le temps de bien expliquer les choix aux clients. Ils se sont présenté à l’heure déterminée et le résultat du travail est clean. Ils ont pris le temps de tout tester avant de partir. Sa plate-forme d’envoi de photo pour estimation et facturation est super simple d’utilisation aussi. Bref, je recommande assurément. »
