Excellent, efficient and professional service!
Miguel was great. Showed up an hour early (usually a good thing but this time I was away until shortly before the planned time). He got right to work, did all windows in and out as promised. No revision of the price. All good. We plan to ask them back as needed.
The team at Mt Diablo was exceedingly professional and friendly, and my house is absolutely sparkling! Booking was easy and they got us in quickly. I will be back, thanks Mt Diablo!
Friendly and professional staff, great service!
I am extremely pleased with my window cleaning. The windows look spotless in a way I can't achieve. They were also able to schedule the work quickly which I needed. The two person team was very friendly and I felt comfortable with them going into all of our rooms. Lastly, they wore booties they brought for inside which is also very important to me.

Although I had to reschedule my appointment several times to coincide with the installation of the new shutters for our…
