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.

« 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. »
