Austin and Patrick from Spectrum did a wonderful job cleaning the inside and outside of all of my windows. This was quite the challenge since I have a 3-story house and many of the top floor windows aren't easily accessible. They were extremely pleasant to deal with and even went back and rewashed windows that I thought looked great but they thought weren't up to their standards. Spectrum also did an incredible thing on the day I had my windows washed--they donated the entire amount of the job to Watson Children's Shelter! I will definitely recommend them to my friends and will most certainly use them in the future. read more

I got their number from a garden sign while out walking one day. My call was answered immediately and after a brief discussion, an appointment was set for cleaning all the windows of our home. An email confirmation followed that same day. I received a reminder email and phone call the day before the service. Thomas and McKenzie arrived promptly, were dressed professionally and described their process to me. They did a great job in minimal time and the invoicing, payment and receipt process was flawless. Our windows look fabulous. Highly recommend this service and we will definitely use them again. read more

This was our first time using a company for our windows. A good friend used to have her own window washing business, so our standards were high. They scheduled me THE DAY AFTER I called - and the price was more than fair for inside/outside two story job. Devin and Nathan were on time, friendly, worked quietly and efficiently - and Devin seemed very knowledgeable about the work. My only suggestion for improvement would be to take care not to leave drips or fingerprints on while sills/window frames; maybe a final wipe down before leaving. In any case, would definitely hire again. read more

Consistently reliable. Sid and his crew are the best. They clean our windows once a year, installed Xmas lights and removed them as well. Sid went the extra mile when a bit of paint peeled off when removing some of the Xmas lights. He came out the next day, got a paint sample, had the exact color mixed up, then returned promptly to repair the small damage done. He even took time to touch up another spot he saw from Montana winter wear on the exterior. This company is rare! Unheard of these days to be not only kind but consistently reliable. Call them now! read more

We are repeat customers with Spectrum Window Cleaning because they are professional, on time, courteous and efficient. They clean the high gutters on our two story house and all the windows inside and out. They also clean the glass shower walls. The ceiling fans that are high up get dusty and the Spectrum guys reach the fans with their tall ladders. We highly recommend all of their services. read more
