I would say most of the larger construction/excavation/property maintenance companies in my area are named after people. Some of them have opted to abbreviate. For instance, "David Manning Inc" is marketed as "DMI Paving". I see a lot of other three letter names here that I have to assume are also someone's initials.
If you like your name, as most people do, but are just hoping to sound like a larger company, you could go with an abbreviation, or use your first and last name, and/or even drop the 'window cleaning' from the end. Like Troy Jones, Inc. TJi maintenance/cleaning/solutions/etc.
Or you could do like I did ~7 years ago, and come up with something entirely different. I was marketing myself as "Alex Lacey Pro Window Cleaning" up till then.
I like my business name now. But in the grand scheme, I don't think the name itself changed much in regard to my success. The best changes I made around that time had to do with looking legit. A decent website, uniforms, large signs on the vehicle, shiny cards, etc. All of those could have been done with my name. But I think making the name change acted as a catalyst of sorts, getting me excited to make all the other changes in branding myself.
So a name change might actually do you good, if you allow it to catalyze your overall marketing approach.
