I have tried four window cleaning services in two years, and Capital Cleaning is by far the most professional, thorough and timely service. Peter provided a quote and phoned the night before to confirm the appointment. Gale arrived on time and finished the work within the four hour estimate. Best of all? The windows are impeccable, inside and out, not a streak to be found! Many thanks. I'm saving the Capital Cleaning business card and tossing the rest.
