Controller Repair Montreal: PS5, Xbox, Joy-Con

Controller drifting on its own, buttons not responding, mushy triggers, a controller that won’t charge or won’t pair? It’s repairable — and almost always cheaper than buying a new controller. At Sub Tech Repairs in Montreal we fix PS5 (DualSense), PS4 (DualShock), Xbox Series and One controllers, and Nintendo Switch Joy-Cons / Pro Controllers, with a free diagnostic and a 1-year warranty.

What we repair on your controller

Joystick drift — the cursor moves by itself: we replace the analog stick module (PS5, Xbox, Joy-Con).
Buttons and triggers — stuck buttons, broken L2/R2 or LT/RT triggers, springs, DualSense adaptive triggers.
Charging port and battery — controller won’t charge, battery won’t hold, ripped USB-C port.
Connectivity — controller won’t pair over Bluetooth or disconnects mid-game.
Liquid damage — internal cleaning after a spill.

Is stick drift really fixable?

Yes. Drift comes from a worn potentiometer inside the stick module. We replace the whole module — on Joy-Cons, DualSense and Xbox controllers alike — which fixes the problem at the source. Same-day service available for many common repairs, depending on model, parts and damage.

Repair or replace?

We’ll tell you straight after the free diagnostic: if the controller is too far gone for a repair to be worth it, we’ll say so. The console itself can also be the culprit — if the problem is on that side, see our PlayStation repair, Xbox repair and game console repair in Montreal pages.

Do you fix Nintendo Switch Joy-Con drift?

Yes — it’s one of our most common repairs: we replace the Joy-Con stick module (left or right) and the drift is gone. The diagnostic is free and the repair carries a 1-year warranty.

My PS5 DualSense won’t charge — can the port be replaced?

Yes. A ripped or worn USB-C port is replaceable, and if the real culprit is the battery or charging board, the free diagnostic shows it before any repair.
