I received multiple…read moreoffers from multiple businesses, but Mount Diablo window cleaning was not the cheapest but provided an in-depth listing of services provided and had a very, very reasonable rate. I also appreciated their services mentioned they would do their best to clean older windows and screens but have to be mindful of their condition. It's not one size fits all Day of service- they arrived at the end of the window time frame - that's totally ok. The work was done in a little over an hour. Two guys showed up- one hit the inside the other did the outside. My windows look brand spanking new. They even cleaned my skylight in the kitchen and it is so bright in there. I don't think I've ever seen my kitchen lit up as much as It is after this cleaning. 10 out of 10 would definitely recommend. The guy who worked on the inside of the house was super nice super friendly with my dog that was going crazy at the time. Asked me what her name is and tried to calm her down. I wish I had before photos.

I reached out to about five vendors through Yelp's project quote request tool, and Mt. Diablo stood…read moreout right away. They were quick to respond, handled the quote virtually (which was super convenient), and offered the most competitive pricing. Scheduling was easy, and when I needed to reschedule, they were incredibly flexible and accommodating. All done via text, which was great, but I'm sure I could have called if I wanted/needed to. Communication was excellent throughout, with helpful text & email reminders along the way. The technician who came out was professional, so friendly, was lovely when my kids wanted to ask him a million questions, and very respectful of our home. And most importantly--the windows look fantastic. Everything feels brighter and cleaner. Very happy with the experience and would absolutely use them again!

We had a great experience with Golden State Window Cleaning. As you can read all those great…read morereviews.... "Yes, definitely what they said!" This was our first service to clean our gutters so it had a lot of pigeon poop and a huge chunk of volunteer plants. (Hubby thought he could clean it himself someday lol) Jose was very easy to talk to. You know that instant vibe when you know a person is genuine... he and the crew were professional and respectful. Their company van is eye catching! So much pride in the design and uniforms! I like that they send videos and/or pictures of before and after. My husband is starting his service business and this is exactly what I want him to do....show customers proof of services, honesty, respect , integrity and veteran discount. Jose was so nice and humble to offer tips if my husband had any questions. God blessed us with this business. They had the best pricing among the estimates I received. I will use them for all their services and refer them to everyone! Thank you Jose and guys for your services and Veteran discount. Blessings to you and your families!

Had an issue over the winter with water getting through one of our window seals. The boss (my wife)…read morewas convinced it was because we'd never had our gutters cleaned. I searched Yelp for a five-star gutter cleaning company, found Bargain Window & Gutter Cleaning Services, and decided to give them a try. It turned out to be one of the best home maintenance decisions I've made. I contacted Joshua through Yelp Messenger, and he responded almost immediately with a quote. He requested my address, used Google Maps to inspect the roof remotely, and we quickly scheduled a full gutter cleaning. The service included complete removal of debris from the roof and gutters, a thorough rinse of the entire gutter system, flushing all downspouts to ensure proper drainage, and photos and videos of the completed work sent directly to my phone. Here's where things got even better. While cleaning the gutters, Joshua noticed several roof tiles that were cracked or out of place likely the real source of our leak. After a quick trip to the hardware store for some roof tile repair adhesive, the problem was fixed. Joshua, it was an absolute pleasure working with you. I really enjoyed our conversation, and don't forget to get those Meta glasses! We'll definitely be calling you again for roof and window cleaning. Thanks again! Brian M Paden
