Gu-Wi Gutters & Windows - Seattle, WA

Got my gutters cleaned today. The Gu-Wi team was quick and efficient. They were also able to accommodate the really tight spacing between houses in my neighborhood. Nicely done!

This business has great service and is knowledgeable in their field. Our service tech provided great attention to detail and follow up as well.

Be warned: this company does satisfactory work on roof & gutters, but the invoicing and customer service are a nightmare.

I used this service in 2020 and then signed up for an annual maintenance plan. The first service was invoiced in a timely manner, with photos documenting work performed, and was promptly paid.

The next 3 annual services were never invoiced and I did not notice the absence of an invoice. Over 3 years later, when I got a call saying my account was overdue and I owed over $2,000.00. It was explained their invoice system was at fault and they had never been sent to me.

I have no confidence in the accuracy of Gu-Wi's invoice system for the following reasons:
-Invoices from Dec 2021, Dec 2022, and Dec 2023 were sent to me for the first time January 6, 2025.
-3 invoices each for $693.93, without any dates service, all generated on the same date of 12/26/2024 without photographic evidence of work performed demanded payment. These seemed possibly fraudulent.
-I contacted GU-WI and explained I would not pay invoices without documentation the work was ever done, I asked for invoices with dates of service and photographic evidence of work performed.
-3 revised invoices, each for $346.42 were provided. There is no explanation for the change in the amount due, nor which is accurate.
-Each of the 3 invoices included a date of service, and each included the very same set of 50 photos without any associated dates of service. Gu-Wi could not tell me which photos are supposed to be associated with a particular date of service.

I spoke with my account manager, Hassan. He apologized and said he would respond to my concerns. Over a week later and one follow up call, no reply from Gu-Wi, except for my first PAST DUE notice to pay or I would be sent to collections.

I contacted Misty, and she also offered to send documentation of work performed by date of service. She sent me over 100 photos without indicating which photos were of my home on any specific date.

In summary, I paid the invoices, because my personal calendar confirmed Gu-Wi was scheduled on the dates of the invoices.

No one from Gu-Wi has apologized for their inept use of the invoice software, the inability to provide documentation of service performed, the reason I was originally invoiced for double the amount due, the inconvenience of a 3 year delay in billing, or the un professional behavior of the employees.

I needed new gutters on my 3 story building, and Gu-Wi was able to do it exactly as I wanted. They offered many options. They were willing to work with me on details to reduce the price, such as disposal. The crew was very professional and communications were thorough. Would use again in future.

We have used Gu-Wi for gfutter clearing as well as other tasks over the years and they have always provided a wonderful service. Most recently, Miguel showed up to do pressure washing, roof sweeping and gutter clearing - he did a superb job and we will definitely be working with him in the future.

I've used GuWi multiple times for gutter cleaning. The techs always do a good job, and I like the fact they also offer other services if needed.

My downspout had fallen off and my gutters needed cleaning. The installation was fast and professional. Very happy with the quality of the work.

Love this company! They have really saved me as I just can’t get myself to climb up on the roof to clean off the leaves, etc. Friendly staff who provide excellent customer service!

I keep coming back to Gu-Wi for gutters and roof-cleaning because they are so reliable. Most recently, their tech, Rodrigo, cleaned my gutters and roof and treated the roof to slow moss growth. He did a bang up job and a very thorough cleaning of my yard and driveway.

Omar did an awesome job cleaning up our roof and gutters after the latest storm pushed a ton of needles off a nearby tree on our roof. He also cleaned up all the debris around the house and cleared off the porch and deck. Thank you for the awesome job well done.

So many issues with the customer service side of Gu-Wi. It was honestly laughable at a certain point. The actual cleaning was closer to a 3/5 star experience, missing windows, forgetting screens, etc. When I reached out to see if they could finish the job, their inability to just be gracious with a customer request was beyond unbelievable. It’s as if the entire team has forgotten the most basic element of a quality customer service experience—customer satisfaction. Instead, they had the gall to defer blame, deny responsibility, even implying that their negligence was somehow the fault of the customer.
Mistakes are part of doing business, and are actually a perfect opportunity to win a customer over for life.

Grayson did a wonderful job! Very happy with the results and the leave no trace cleanup. I have been using them for a a couple of years now and I highly recommend using Gu-Wi for gutter cleaning. Great quality and value.

Gu-Wi team did a great job to clean my house gutter, it was not cleaned for past 3 years and there were many water blocks in the gutters due to heavy junks and leaves. Everything cleaned properly and water is flowing smoothly now. Thank you for your help. Will work with you in future.

Rodrigo and Miguel did an excellent job on extensive window, exterior gutter cleaning and clearing, and roof moss removal project on my 2 story house. They worked so diligently and were very responsive, polite, and respectful. They got all this work done in less than one day and for a competitive price everything looks clean and fresh!

I commend their hard work through a cold and rainy Fall day. Would definitely recommend GuWi to anyone who needs similar maintenance. I plan on repeating this service in the future. Five stars all the way!

Disappointed. Everything was text, no personal interaction. Had a small gutter repair. Was sent quote. Accepted quote. Get a call from technician day of who says he does not have the right ladder. WHAT? You repair roofs and gutters and don’t come prepared? Then he blames the issue on something absolutely unrelated. Thankfully my main person came out and saved my home sellers bacon. I am sure this company is fine, probably does good work most of the time, but I won’t be coming back.

The crew at Gu-Wi do an excellent job. Efficient, thorough, and easy to work with for gutter cleaning. Great communication too. Highly recommend hiring these folks!

We were prepared for the process and impressed with the service. Great team and good work. Thanks for the help!

Gu-Wi did a great job cleaning our windows and gutters. Want to give a huge shoutout to Miguel and Rodrigo for being so diligent in taking down the screens , cleaning both the inside and the outside of all windows and doing all of that with care and attention to detail! Thank you so much!! For anyone looking to clean their windows and gutters, I highly recommend Gu-Wi!!

The team did a great job and in addition they were very nice. I will definitely call them again for the next gutter cleaning.

I've had Gu-Wi out several times. I'm always impressed with the level of care the technicians put into their work. Very happy to have clean roof, gutters, and windows again! Thank you!

Gu-Wi did a fantastic job on my gutters. Communication for scheduling was quick, effecient and my questions were throughly answered. I was made aware of/offered additional services, but there were no high-pressure sales tactics. I was told what was found and how it was taken care of. There was a lot of respect shown for my property, debrie that ended up on my deck, house and drive way was cleaned up, which since I had recently had everything power washed, was greatly appreciated.

we had all our exterior/interior windows cleaned by GuWi. Jesus did a phenomenal job. I tend to be fussy and he surpassed my expectations. The price was reasonable, he was efficient and professional. I would definitely recommend this company.

great service and save me a ton of trouble! very happy with their work and will continue using them for cleaning

I've used Gu-Wi several times now and am always happy with the work. They give you an estimate beforehand and can provide photos of the work as well. I love how easily the windows and screens slide after their visits (the track cleaning service is a must!). Staff is always professional and courteous, and the work is usually done faster than I expect.

Service requested:
Old wire covers removed
New guards installed
Exterior gutter cleaned

Gu-Wi crew was responsive, careful, quick and very
skilled. Highly recommended! Great experience all around.
Thank you very much!

Hello,
I can't praise that team enough. They did a fantastic job, and our roof was in terrible shape. Had never been cleaned and had moss that was inches deep in some places. Also we are landscaped right up to the wall, and they didn't damage anything. Cleaned up perfectly. Miguel and his crew were terrific!

my contractor hired this co to install the gutter but, it tilled and water not drain properly. contacted this people and Jesus came back to fix and clean it professionally. Thank you Gu-Wi

Gu-Wi has great prices and service. They did the work in less than half a day. They cleaned up well did all the work right the first time. Their payment and scheduling system is easy to use.

Gu- Wi gutters and windows did an excellent job. Estimator came out and gave us a very reasonable bid. Signed up that day. They returned a week later. They cleaned off our roof with a blower. Lots of pine needles from all of our wind storms. Cleaned gutters, cleaned up debris. Everything, from scheduling, response time, ease of payment were 5 star. People in front office, polite, knowledgeable and friendly. WE WILL ALWAYS USE GU - WI for our roofing issues.
We've lived in our for 37 years, best ever!
Thank you!
Margaret and Lance

Your team came to my house to do a roof cleaning and gutter maintenance, they did an incredible job. there are clients who give bad reviews to this company But in reality it is a great company that helps the community very good experience on my side

I don't normally put local businesses on blast in reviews, but I am at my wit's end with Gu-Wi.

Gu-Wi quoted me to install soffit venting to ventilate my house's attic, then installed the vents in such a way that they don't actually connect to the attic space. So to start off with, they didn't actually fix the problem they quoted me to fix. At all. Or attempt to verify that the attic ventilation was connected to the attic after they installed it. Or check with me on-site to review and approve the work they did before quietly legging it. Oh, and their crew left garbage in my yard that I had to clean up after. Great.

Then after hounding them on the phone for several days, they sent their carpentry manager out to actually look at the problem and then come up with a new plan to vent the attic. He acknowledges the problem, says he'll suspend the invoice until they come up with a new plan to resolve this, and says he'll get back to me.

Apparently that new plan was to tell me that my insulation contractor is going to fix the problem. I had to follow up with the insulation contractor to verify (as you might well have guessed) that not only is that work not part of their bid (which was my understanding with them to begin with), but they also helpfully added that in their opinion, Gu-Wi's plan to ventilate the attic was never going to work in the first place no matter how they did it due to the small soffits and relatively large amount of ventilation needed. So I wasted another week playing phone tag to verify another incorrect claim from Gu-Wi was, in fact, wrong.

At this point I'm in a mouse maze talking to one front office staffer after another all of whom promise me callbacks that don't happen from "upper managers" who mysteriously turn out to be "out of the office" and I've started getting harassing phone calls about this invoice while one person after another passes the buck and claims they don't know what's going on.

Avoid. Gu-Wi doesn't know what they're doing and if anything goes wrong you are going to be trapped in purgatory trying to get it resolved.

The communication with Gu-Wi is extremely proactive and their process is very efficient. I’ve completed one job with Gu-Wi for window washing. By text I received constant updates at where they are in the scheduling and estimate process. If they need additional information or to do an on-site walkthrough, they ask for that right away and keep the process moving forward. The estimate is sent nearly the next day, and it is broken down into the individual job parts with prices and description. You get to pick and it totals it up at the bottom, you click Submit and they call to schedule the next day. Their work is excellent. They made 4-stories of new construction windows sparkle!

Now we’re having them come back for some pressure washing and their process is still spot on. Very professional, courteous, responsive, super easy to work with, fine pricing. Thank you Gi-Wi!

I had complained recently in a Google review about a gutter repair performed by Gu Wi which had failed in just over a year (gutter had been reattached to my home by them but had pulled away again). They were very responsive to my critique and after some discussions came out to readdress the issue,. Based on recent rain, they appear to have fixed the problem. They were very conscientious in addressing my complaint and issue. Thank you.

Great to work with. Gave us a good quote that was reasonable. Scheduled and completed work right away. Kept communication through process of replacing all gutters on house.

this is a service of the best I love this company for its business of great help for me and the community

A great business, providing roofing, guttering, power washing , window washing, moss removal, and a slew of other misc. home services.
Honest prices coupled with a great staff of knowledgeable and easy to work with individuals, would highly recommend.
