After years of great gutter cleaning and a first time with window exteriors in 2022, we opted to do it all this year. I no longer can the interiors myself as vision and health challenged and I am so glad it was done so well today. If you read my previous review, you can see how challenging our home is to service. We have removed some of the trees which has helped immensely with the debris in our gutters and and cleared more for fire and wind safety too. Benefits the gutter situation also. I will definitely use Glass Gecko again. Every member of their staff has always been efficient, courteous and safe. And we love supporting a homegrown Boulder business.

The windows look great, but the screens were still dirty after their cleaning. In my opinion, dirty screens sort of cancel out the clean windows. Arrian was not with the two men who worked here.

I think in order for this review to get out to you all, I have to give it at least 3 stars but I…read morewould give them 1 star if I knew my words would be heard. How many bad reviews with 1-2 stars have they got and the public never sees them because of filters? Well, this is my story and I hope you read it to the end. The words from the owner, Pete, were shocking! If you question their charges..BEWARE! Have any of you ever been quoted one price over the phone, booked a service and then ended up being charged $100 or more over the quoted fee? That is what happened when we hired this company to clean our windows. They charged me for 45 additional windows that I didn't have cleaned! After writing a check, we realized this overcharge and 'immediately' called, emailed and text the company. I finally got a hold of the girl that gave me the quote and explained that I had been over charged by $100. She tried to tell me that my 5 larger windows counted as 2 windows even though this was not told to me when I received a quote. I told her that they did not clean any of the inside windows downstairs or upstairs and that the cost according to the quote should have been between $225-$250 at the most! She was going to ask the cleaners about it and get back with me. I didn't hear a word for the next week until I finally sent an email today. (I assume they wanted our check to clear the bank before calling me back) Well, today I finally received a call from them and an appointment was set up to come out on Thursday to count the windows together and figure the correct cost. I was happy to meet with them to get this finally straightened out. It wasn't even 10 mins. later and Pete himself called me back. I was happy that he would take the time to call....but it wasn't long before the call turned into to an extremely rude business owner hanging up on a client. He was nice at first and I was quite impressed that he would take the time to call and get my side of the story........as the conversation went on, I explained how many windows I had asked them to clean inside and how many outside. I also explained to him that I was NOT told that larger windows count as doubles. I let him know that I am happy to pay what is due and have even given a generous tip to other window cleaners when the job was done well. Abruptly, Pete became more rude saying that "they didn't need to tell me about all the additional charges because it is in all the emails they sent me when confirming the appointment". (FYI: I clicked on their 'terms and conditions' link at the bottom of the emails and it brought up a BLANK page so that was a lie.) Then he proceeded to tell me, "Listen, I will send someone out to count the windows with you and if you are correct about the $250, they will write you a $100 check right then, BUT...... if we are correct about the $350, what will be "YOUR CONSEQUENCE" be for taking up my employees time in coming out. Are YOU going to write them another $100 check" WHAT. . . . !! I could hardly believe what I was hearing folks. All I can say is.... I hope you are reading this to the end and can make a decision from this review. I feel like they are crooks!
