5.0
they phoned me. In half an hour time, two real nice guys came in and replaced my thermostat in approximately half an hour or a bit longer.

Also, back in January I used Mark Allen for a leak I had in my garage...my toilet needed replaced.

Every person from this company that came to my home was very nice and respectful. And knew what they were doing.

I highly recommend this company.
4.0
The worker was quick and professional. Worker was friendly and personable.

The completion process with completing the form before the work could be completed was unnecessarily complicated and took too many phone calls to figure out. I finally did thankfully because I figured out only the last 5 digits were needed instead of the entire SSN#

I’m happy so happy this is finally completed.

I scheduled an appointment with Service Experts to have a yearly service check of my boiler on September 28, 2026.
Service Exports tech, Gregory, arrived on time, and was professional and efficient.
He explained what he checked very clearly, and answered all my questions.
I very much recommend Service Experts for any home maintenance needs.
