options, not pressure

We guide. You decide.

We present your options and you choose – no high pressure close. Explore the honest pros and cons of each below.

Detector Evaluation

A licensed electrician evaluates your home's existing detector coverage and condition to determine what installation would involve.

Often A Good Fit When

You're not sure whether your current detectors are adequate and want a professional evaluation.

Pros

  • Gives you a clear read on your current coverage
  • Costs less than the installation itself
  • Helps you plan ahead
  • No obligation to move forward

Cons

  • Does not install anything on its own
  • Not every home's layout has the same needs
  • May confirm installation is the right next step anyway
DIY VS PRO

Should you do it yourself?

Once your detectors are installed, pressing the test button on each unit periodically is a simple, manufacturer-intended way to confirm it's responding.

Installing, wiring, and interconnecting detectors calls for a licensed electrician. If a test doesn't respond as expected, a McQuillan technician can take a closer look.

DIY versus Hiring a Pro
An Honest Comparison DIY Hiring a Pro
Time Seconds per detector using the test button Often available same-day
Real Cost No cost Upfront quote before work
Insurance Not typically applicable Provides a documented service record
Warranty Not typically applicable Backed by our workmanship
Safety Safe using the manufacturer's built-in test button only Handled by a licensed electrician

Do the looking. Leave the fixing to us.
