Step 1 — Call TMC Before You Cancel Anything
Before dealing with ADT, call us at 1-866-247-4999. We'll confirm your equipment is compatible and walk you through the smoothest path to switching — often without any service interruption.
Step 2 — Check Your ADT Contract End Date
The best time to leave ADT is at your annual renewal date — typically 30 days' written notice before renewal avoids any early termination fees. If you're mid-contract, fees may apply, but the long-term savings with TMC often outweigh the short-term cost.
Step 3 — Give ADT Written Notice
ADT requires written cancellation notice — a phone call alone isn't enough. Send written notice via certified mail, keeping a copy for your records. Include your account number, service address, and desired cancellation date.
Step 4 — Schedule Your TMC Takeover
A TMC technician reprograms your existing panel to connect to our monitoring center. The visit takes just 1–2 hours and your monitoring goes live the same day — at $9.99–$21.99/month instead of the $40–$60/month ADT typically charges.
Ready to Stop Overpaying?
Switch to TMC and get up to 6 months free monitoring. Call us first — we'll confirm your equipment qualifies and make the transition seamless.
