Testimonials
A word from our clients
This was the first cleaning service I've hired and they exceeded my expectations. The cleaners were kind, polite, and were extremely detailed in their clean - way better than I could've done myself. Highly recommend 🙂
Exceptional service! Four Seasons Cleaning was on time, friendly, and very thorough. They made sure every surface sparkled. Highly recommend!
I can’t say enough good things about Four Seasons House Cleaning! We’ve hired them for several deep cleans, and each time, they’ve exceeded our expectations. Their attention to detail is truly remarkable—every corner, surface, and hidden spot sparkles when they’re done.They’re consistently punctual and reliable, which makes scheduling so easy. Plus, their communication is top-notch; they keep us informed every step of the way and always check to ensure we’re satisfied. It’s clear they take pride in their work, and it shows.If you’re looking for a professional, thorough, and trustworthy cleaning service, I wholeheartedly recommend Four Seasons. They’ve made our home feel refreshed and revitalized time and time again!

Four Seasons Cleaning did an incredible job on my home! The team was thorough, professional, and left everything spotless. Highly recommend
Absolutely incredible service! My home looks brand new every time Four Seasons cleans. They are efficient, professional, and thorough. Highly recommended!
We just had our first cleaning form Four Seasons Cleaning and our home was so clean when we returned! We opted for the deep clean for the first visit and then will go to the every other week cleanings thereafter.This has been a very hard year for my family with my aging parents who live on the peninsula and I've been going there to care for them and working about 50 hours a week. My home had gotten out of control! I had to decide to do something about it and not be so hard on myself emotionally. This is a real winner! Thank you so much for your great work!!!
We have been customers for almost 10 years. We appreciate walking into a clean and tidy home after each cleaning. The staff is kind, courteous and professional. We love their new technology which notifies us of the exact time they will be arriving.
The particular crew sent today (9-17) was excellent. They cleaned thoroughly including all the nooks and crannies. I really appreciated their extra efforts.
So very happy with the the every other week cleaning by the Four Seasons cleaning ladies. They are quick, thourough, kind and always willing to hear my suggestions and feedback. With 2 collies and me with a spine injury I know I will never go back to trying to do it myself!
The cleaners from Four Seasons just left my house where they did an initial deep clean. They did a phenomenal job, and I will definitely employ Four Seasons for ongoing maintenance. Both cleaners were highly professional, focused, thorough, and friendly. The scheduler I talked to when setting up this initial visit was also very friendly and responsive. I filled in the "get a quote" form on the Four Seasons website about two weeks ago, she called me within 5 minutes, and I had an appointment set within ten minutes (I had been on a waitlist with another service for about six weeks when I called Four Seasons). This was my first time hiring a cleaning service, and I am so glad I chose this team.
We've been with Four Seasons for years now. They provide reliable and a consistently high quality cleaning service for a reasonable price. We've been with other services and private cleaners in the past and had problems with consistency or nickle & diming for basic services.
I worked with another cleaning company but they recommended this company to me and I decided to try it and I was really impressed with the result. The two people who came to clean (Marina and Yaniris) were very professional with their work, leaving everything sparkling. Totally recommendable. I hope that when I need another cleaning service, if other people come, they will work just as well as them.
The last several times I was not happy with the cleaning. I had left a message a told them about what I was upset about and today Mia came in and was very diligent and I was able to let her know my expectations and she was very helpful and did a very good job and things were done better I appreciate that I was able to get my house cleaned to my expectations. Thank you
Very professional and happy crew came to clean our home! They were extra kind to my children & super thorough in their work. I’ve never seen my home this sparkly clean! Thank you very much for all the help!!
For this particular cleaning, my house was in good shape after the cleaners were here. Looking a little closer at the toilets and tub, they weren’t completely cleaned. I give my son a bath every night, so the tub has very regular use - there was a ring around the tub left, and the toilet was not completely cleaned with rings left there as well. Everyone here is very friendly, great to talk to, and receptive to feedback. I have no doubt it’ll be better the next time, but it wasn’t 100% clean this last time through.
We have been using Four Seasons twice a month for over a year and are delighted with the service. I know my 83 year old back is feeling better because I do not have to wield a heavy vaccuum cleaner around the house on a weekly basis like I used to, and the bathrooms---even the little-used guest bathrooms--just sparkle. It's like moving into a posh hotel with familiar furniture. We have had several different crews on site and they all performed magnificently! Many Thanks to our latest team Rosana, Patricia and Evangelina!
While we normally love our service, the last time was exceptional. Yuri cleaned all the nooks and crannies in the house (areas that are normally missed) and took care with arranging things. This stood out among the normally great service we already get.
I have been using Four Seasons Cleaning for several years and absolutely love them. Erica and Jessie do an absolutely outstanding job every time. They are very detail oriented and take their time cleaning all our high traffic areas! Can’t recommend this team enough!
Wow, I was at the end of a home renovation with the movers coming, Everything was covered in dust.Four Season Cleaning Service was there to help. My sister has used them since 2011. 2 cleaners arrived on time, another showed up 1 hour later and the supervisor at the end. I was very impressed.Even with construction workers still in the home working, Four Seasons Cleaning was able to get the job done.NO smelly toxic cleaners. The home was ready for the big move in. I am hoping to become a regular customer.Thank-you Four Seasons Cleaning!
Four Seasons is very efficient. I love the ease of payment. They do not expect tips since it is built into the cost. They were reliable and I received a phone call if they were ever delayed for some reason. My home was very clean when they left. The first couple of months of service I let them know of little things that were not cleaned and I never had the issues again. I highly recommend Four Seasons!
Mary, Dianet, and Krystal did a wonderful job cleaning our home. It is such a stress reliever to have their help especially during a busy time of our lives. We are so glad we found Four Seasons Cleaning!
We've utilized Four Seasons for over five years at our home. The cleaning teams are top notch and we couldn't be happier with the service. The recent team, Biri and Rud, cleaned our house for the first time and did a terrific job. I couldn't recommend them enough.
I want to give a “shout out” to these amazing ladies. They performed a deep clean of my home and did amazing.job. Thank you Rosa B and Olga for making my home feel new again!
A nice lady names Rud helped clean my apartmentWas about to move out and needed the apartment clean before inspection.They came in time and gave me a reasonable price.Great service!
I've used Four Seasons Cleaning for about 6 months now and their teams do spectacular work. About 2-3 women come and spend 2+ hours doing a full scrub-down. Bed sheets are placed in the washer, the home office and library are dusted, and they clean my Breville espresso maker, too. Attention to detail is made with the corners of floors, dog hair removal, and even the bottom of my toothbrush holder. They save me an entire weekend of cleaning. I recommend them without any reservations.

I've been using Four Seasons Cleaning for over a year and they do a very solid job. Maria Gomez is a cleaning wizard and always makes my home feel so clean and comfortable after she's done.
Zendi and Yuri, are the best. The house is sparkling when they leave! Thank you for your hard work!!
Maria G came to clean for me last week. She was absolutely incredible. She cleaned every nook and cranny. I didn’t even know I had in the house. My Wood floors haven’t shined that much in a long time. I wish you could come every time.
Super happy with the cleaning service I've received. Definitely removes hours out of my life and helps me focus on other things. Thank you!
Very impressive. They cleaned more than I asked for and in less time than I hired them for. They used my stainless cleaner as requested. I was stunned they cleaned my embarrassingly messy laundry room and shoe rack. I saw they did detailed dusting work of bowls of shells. Bathroom is well disinfected and they got the rust stains out of the tub. What was also cool was that the garbage cans were cleaned as well as emptied. They moved light furniture while vacuuming and cleaned our couch cushions. The supervisor came by to inspect, too.
Bekki is best custodian we have had yet! We have been through well over a dozen different employees from 4 Seasons in 2 years cleaning our business and Bekki blows them all away!! Professional, on time, consistent, great communication, and a pleasure to work with!
Fabulous cleaning services, the best I've used in the Seattle area. Consistent in timing and cleaning, friendly, and great value for the cost. They are thoughtful and careful too. Highly recommend!
We love Four Seasons House Cleaning Service, great detail oriented staff, trust worthy and always friendly. Thank You Maria, Bekki and all the others we very much enjoying your support.
We have been very satisfied with Four Seasons Cleaning over the last two years. The company is responsive and flexible, and the price is very reasonable, especially given the great level of service and detail they give our house. Betty and Maria continue to do a stellar job and continue to surprise us with the level of care and detail they give our home. Highly recommended!!
Awesome cleaning by Deborah and team. I have been a customer with 4 seasons for a year now. Thanks to four seasons Bothell for always being accommodative, on time and a wonderful cleaning service
I received a recommendation from a friend and I was not disappointed. I got a deep clean before my extended family all arrived for the holiday, and my house looks so nice! Debora and Hailva (apologies if my spelling is bad) took so much care in every room. They were able to get things off my stove top that I assumed were permanent. It looks so clean, I may not let my kids back in the house.
I've used Four Seasons Professional cleaning since 2007.I have very high standards and I expect my house to be perfectly cleaned.Four Seasons does a perfect job for me every time.In addition, the house cleaners are friendly, warm and respectful.They work extremely hard.They are also very responsive in their office responding to emails for schedule changes as well.I highly recommend them!
Yezenia and Silvana are such a pleasure to see and do such perfect, spotless work. We feel so fortunate to have found them and Four Seasons as a company. They are very reliable, trustworthy, quiet, respectful and very kind. Highly recommend.
It is the best cleaning company I have met in Washington state.
I used their service for a move out deep clean. I was very satisfied and I think they did amazing and were very responsive 🙂 I would definitely use their service again 🙂
4 Seasons has been cleaning my business for several months now and they do a wonderful job. The staff are professional, prompt, and do a very thorough job.
The ladies are prompt, and do a thorough job of the basics as well as any extra attention areas that we requested. We are pleased with the service and find it to be well worth the price they charge.
Carmen and Rosanna (sp) did a wonderful job. They arrived on time, were thorough and were able to finish on time. All in all a good experience.
No cleaning service is perfect. But I’ve tried several and always come back to Four Seasons. I’m especially appreciative of their extra efforts to protect workers’ and clients’ health during the pandemic. I’m grateful for their services and would recommend them to others.
They cleaned our rental home after we moved out and did an exceptional job for us. They showed up on time, had all the supplies and equipment they needed and did a great job getting the house back into shape. I will be happy to use them again and to recommend them to my friends. Thanks for an excellent job!
The cleaning of the house was stainless and complete. All the workers did an amazing job. Well worth my every penny. Very grateful for the service offered!
This is one of the best cleaning services. If I could give them more than 5 stars I would! I am very picky when it comes to cleaning. They are so detail-oriented! I am extremely happy with their services and will recommend them to my family and friends. Thanks for the great job!
They were available to clean at last minute for me and did a fantastic job. Seriously such a great value for the price. I will definitely use them for all future cleaning needs.
I have been using this service for years and have always been satisfied. They have great prices, punctual, polite, efficient and work quickly. I recommend this company highly.
They went above and beyond! they cleaned every nook I could ever think of, their attention to detail is amazing. they are more than worth every penny! i will be going back for regular cleanings! Do your self a favor and have this amazing company clean your place for you!
So impressed with the attention to detail and professionalism of Four Seasons cleaning. I’ve used them for a standard cleaning many times and am always extremely satisfied with their work. Hardworking, efficient, prompt. Even my kids’ bookshelves and toys had been thoughtfully arranged. I highly recommend them!
We have worked with Four Seasons Professional Cleaning for almost two years. We are so impressed by their thoroughness and professionalism, as well as their attention to detail. We often have special circumstances and are very grateful for their understanding and flexibility. The team that cleans our home adheres strictly to COVID precautions allowing us to feel very safe having them come into our home during this time, even with a high risk member of our household.
