What Seattle Says About World Glass

Zach is a pro. He cleans our windows and gutters every year. He even puts up with our annoying dog. Highly recommend.

Zach is super easy to work with and does great work! We've had World Glass power wash out patios and walkways, and clean the exterior windows. Always a great job.

I have been using World Glass Window Cleaning twice a year for several years. They do an incredible job. Detail oriented and my windows look fantastic. I highly recommend this local, family owned and operated business.

Good communication. Reliable. High quality work.

Zach did an excellent job cleaning our business awnings. The work was able to be done within a week of contacting him. Will recommend his services to others and use again to clean our solar panels.

Highly recommended! They were able to schedule with me quickly, and they finished the job without me having to do much prep work before they arrived. We worked from home while they cleaned our windows, and now we can see out. When I asked for them to do some windows that had longterm stains on them, they threw that in for free. Very much worth the cost!

Zack did a great job for a fair price

Team was orompt and efficient in cleaning our windows inside and out.

Experience was positive from beginning to end. Fast response to online request for quote, scheduling happened once I wanted to confirm. The work was very well done. We have a metal roof that now looks brand new. Also, nice job on skylights and windows, inside and out. Zach was professional, communicated well and delivered exactly as promised. Will use again and do recommend.

I had to reschedule my appointment with World Glass several times due to changes in some travel plans. But WG was very tolerant. Eventually my neighbors had to admit the workers into my house since I returned later than expected.
I came home to sparkling streak free windows. WG did a great job! My neighbor across from my unit commented on the thorough job the workers did and the techniques and equipment they used. I was not here to witness the work, but my neighbor was quite impressed and plans to use WG in the future.

Working with World Glass Window Cleaning was a smooth process from start to finish. I got a quote for cleaning our solar panels in just a few minutes and Zach immediately reached out to schedule an appt. Once here, he did a great job. I plan to use their services again.

Responsive, on time, professional and quality work.

I appreciated that Zach was on time and took care to wear shoe covers in the house. I'm happy with the windows and would use again.

Great service! We haven't hired a professional window washer since buying our house 10 years ago. They were professional, quick, and had good customer service. They were able to be flexible and added some additional elements into the order last minute with no problems. The windows and solar panels look great! I would definitely use them again!

Always prompt, efficient, and does an excellent job. I love that they email me a booking reminder when its almost been a year since the last cleaning.

Amazing. Did a very thorough and beautiful job. Would hire him again next year. Thank you!

This is the third year which world Glass has done our windows. The first year our contractor used them after a renovation . This year we added the window screens. They do a good job. It's worth an annual cleaning to have clear window s.

A+ service, communication, and professionalism.

Excellent service, this is our 2nd year and will continue next year!

Zach did a great job cleaning our windows in June 2021. We had some construction nearby that basically caked our windows in dirt over the last year+, and now they are sparkling clean. Zach arrived early, was very efficient in cleaning our windows and screens, and I would happily recommend him.

Zach does a fantastic job cleaning the windows of my new construction and remodeled homes. I highly recommend World Glass Window Cleaning.

I've had Zach do my gutters and cement/sidewalk pressure washing for several years now. He is extremely reliable and thorough. Always cleans up after. You can count on him keeping appointments even when they are scheduled well in advance. Love the reminder emails he sends out the day before arrival. Highly recommended!

Zach was professional, efficient, incredibly polite, and so nonintrusive, I forgot he was inside our building. 10/10

Every facet from the communication with me about the job through the work and the follow up was top rate. Highly recommend them

We have used Zach & World Glass Windows for several years. ALWAYS good (and I can be difficult to please when it comes to these types of home services). On time, friendly, reliable, professional and an excellent job is what we always get. I recommend highly!

Fast response, thorough job. Would definitely use again.

The Gentleman who owns this business was prompt, courteous, and totally professional. I wish I had only found him earlier.

Zach was a gem. He showed up on the early end of our appointment window, and quickly and efficiently cleaned all our windows, inside and out. Our windows are glowing right now! We will definitely be hiring him again.

Have already recommended to three people with contact info. Wish i had found company ten years ago.

Zach has done an excellent job pressure washing our deck and railings for the last two years. This year I contacted him with late notice to see if he could get the job done before a party I was hosting. He came late on a Friday night just to get it done in time. Huge thanks Zach!

Best window cleaning I have ever had. Highly recommend.

Great communication and work!

World Glass does a great job. Zach is prompt, responsive and very low key. We've had zero complaints since he began doing our Condo Community windows. We always had complaints with our prior vendor. We've even had a couple of owners ask for his contact information to clean their office windows. Highly recommend Zach!

★★★★★ rating with no written review.

Simply put, they did an awesome job!

I found Zack from World Glass Window Cleaning very responsive to my needs. He was able to get me a quote the same day that I had contacted him. I was looking for both pressure washing of the patio, walkways and decks and the washing of the outside windows.
Zack did all of the work that we had talked to and I am very satisfied with the quality and felt the pricing was worth the work.
I will be using this company in the future!

Zack does an amazing job! He’s professional and his prices are very reasonable. I highly recommend him-you won’t be disappointed!

Exceeded expectations! We own a 1905 house and I haven't seen the windows look so good!

Excellent job Zach!

Our service provider was prompt, thorough and responsive. We had gutter cleaning and even more importantly in our case, window cleaning done. We have leaded glass 112 year old windows that require TLC and he did a great job taking care of each window. Also having this service done during COVID19 I felt safe with his PPE and foot coverings. Being inside my house now just got a lot brighter! Thanks!

Zach is great, and my windows look so good! I highly recommend him. He was on time, hard working. and wore a mask/kept his distance when interacting.

Very professional. They were quick to respond with a quote and did a great job on the outside of my windows. I will have them do the inside as soon as social distancing is lifted. I had a few questions during the quoting process that were answered quickly and kindly.

World Glass Window cleaning regularly cleans the windows for a couple of our different offices. Never do we have to worry about when they are coming or if they showed up. They are always there when they are scheduled and they do a great job cleaning the windows every time.

Will absolutely use this company yearly to clean interior and exterior windows! Zach does a wonderful job!

Good thorough cleaning, and nice easy to talk to. No communication issues of any kind. No problems involved in having the work being done in the house while I was in or out of the house. I will definitely use this company again..

I would highly recommend World Glass Cleaning for anyone looking for professional, prompt and immaculate cleaning. Zach is extremely responsive, punctual and precise. Would surely hire him again for all window cleaning.

We contacted WGWC to have our windows cleaned inside and outside; we got a quote and schedule it in a matter of hours. Zach was well organized and professional. He did an excellent job and left no mess behind. Thank you!
I highly recommend him and will certainly use World Glass in the future.

Zach is excellent! The entire process of working with him was easy and efficient. Great communication, response time, schedule fexibility, and prompt time of arrival. Competitive pricing. Detailed and clean. Will use him again!

We’ve had Zach clean our home exterior twice. He is great: efficient, pleasant, and thorough. Highly recommend World Glass.

Zach has been cleaning our roof and windows for over a year now, and we couldn't be more pleased with his great quality service. He's always on time, works fast but with great attention to detail, and is super kind, too. He always does a bit more of what is expected from him, and all at a very reasonable price. Happy to recommend him 100%!

I've hired Zach of World Glass Window Cleaning for 3 years in a row now. He works fast without appearing to hurry, cleans the multiple panes of glass on our doors for no extra charge (unlike many window cleaners), cleans both our skylights, and leaves the windows looking invisible because they're so clear! His price for this service is remarkably low, too. He's very easy to have working around the house and never leaves a mess. Great work!

Responsive, friendly, good prices, and thorough cleanings.

The company I work for hired Zach to clean our large indoor office window. He was very quick to respond to the bid I placed online and gave us an estimate within an hour or two of requesting one. We were able to schedule a time for him to come in quickly and he arrived perfectly within the time-frame he gave us. Very professional and he did a tremendous job. We will definitely reach out to Zach again in the future.

My entire experience with World Glass Window Cleaning was great from start to finish. They cleaned our home window and solar panels and our office windows. I appreciated their online system with its estimating, appointment setting and verification components. Zach was responsive by email and phone and our windows are beautifully cleaned! I also appreciated the care Zach took while inside wearing booties and wiping down the window sills…no water drops anywhere. Finally the online system billing function made receiving and paying the invoice a snap! We will definitely use this service annually and have added World Glass Window Cleaning to our contractor referral list for our clients.

I've used World Glass Window Cleaners at my office a few times now and have been very happy with the service provided. They are very responsive to questions and even come by on short notice. The windows are sparking when they are done. Well worth the money. We will be using World Glass again!
