Good morning Steve, as the 48 Porter Road closing is today, I wanted to take a moment to express my deep gratitude, appreciation for you and to simply say thank you. You were a key individual, member of the team that refreshed the property in our collective effort to get it ready for the market. And it’s not just your skill, specialty that made a difference, it was also your willingness to roll up your sleeves, do whatever you could to help in this transaction. Yes, it’s been difficult, challenging at times however please know that your partnership made things a little - a lot - brighter. Please also pass on our gratitude to other team members that worked on the property as well. Wishing you all the best and looking forward to the next time our paths cross!



Joe did a great job today power washing our house and two decks. He was very professional and explained everything. Green Guys Power Washing is very reasonable in their prices and I would recommend them highly. Thank you again!


Laurel L.

I can’t say enough about this company. Incredible price and they worked so hard for not a lot of money. My roof/house looked fantastic afterward.


Jane L.

Very impressed with the quick response to my husband's inquiry, the time to get an estimate back and to schedule an appointment. Joe and his guy were here today, did a fabulous job on the roof and the house. I know they were going to do the gutters, but since I have no desire to go up a ladder to look, I am going to assume they did a great job on them as well. My husband will check those later I am sure. Joe was super nice. My only negative is that from reading the website, it sounds as though credit cards are accepted . They are but only if you do it online and pay an additional fee. I hope you get a Square for your guys that plugs into their phone or into an iPad so customers have that option. I paid with a check but was disappointed as my favorite credit card rewards me with substantial miles for charges and I lost out on a lot of them. But small complaint - everything else was great.


Cynthia S.

I would like to take this opportunity to say thank you to all of you at the Green Guys Power Washing. Each and every one of you made this a very pleasurable experience, going above and beyond what was expected.


Again, thank you all.



Steve and his son showed up right on time and did amazing job!! We bought a total fixer upper a few years ago that was neglected, and a powerwashing for the exterior was long overdue. Steve was so nice and friendly, offering to add on a few small random things we also decided we wanted washed. The house looks amazing and I couldn't be happier. Steve made a customer for life and I couldn't recommend him or the services more!! ⭐⭐⭐⭐⭐ for sure!

My house is white again! Fantastic Results. Steve was fantastic from Time of quote to date of service! Will absolutely use Green Guys Power Washing again!

What an amazing job Green Guy's Power Washing did on our home!!! We would HIGHLY recommend! Steve is efficient, kind, and thorough! He was willing to go the extra mile to ensure we were completely satisfied! I would never even consider looking to anyone else for power washing, and would recommend Steve and his crew to absolutely anyone who is interested in having their home look like a million bucks! Our house looks brand new! Thank you Steve, you are the best!!!!!


Sincerely, The Grasso's

Josef did a great power washing out house and cleaning out the gutters. They arrived on time and answered any questions I had. Josef was very nice and made sure we were happy with the job. Steve stayed in touch with me when I was making the decision to hire them. He assured me they would do a great job which they did.

Thank you, Green Guys Power Washing, for such an excellent job on our house today. I've wanted to do this for a long time, and it feels like a divine treat to have our house looking so great (and to not have any of the green stuff on the siding and on the wood porches!). FABULOUS!!


Karen J

Steve, You guys did an excellent job on the roof and pool patio! You even were kind enough to pressure wash the front steps. THANK YOU so much and please know that I appreciate your work. The wife and I are beyond pleased with the service and price! Have a great day and let me know how much I owe you for the stone walls.


Joe H

I would not hesitate to hire this company again. Steve was very prompt in responding to messages and easy to work with. He did a great job power washing my house, despite it being a very cold day. He was very thorough...the house, farmer's porch and back landing look awesome! I highly recommend Steve and would definitely use him again. Thumbs up!


Brenda P.

They did an amazing job on the house. I haven't seen the real color on my front steps in years apparently!! Highly recommend and very reasonable rates!!


Miguel N.

Steve was very quick to respond to questions and date changing due to weather. I was very pleased with the job--Tyler did a wonderful job cleaning my roof. I would highly recommend this company


Lynne J.

Great Job Power Washing House in December!


I hired the Green Guys to power wash my house in December in time for Christmas. Steve's bid was very competitive, he was an excellent communicator and they did an great job. Our house looks great. We had a lot of mold on our shingles and I couldn't get my wife out there to clean them. I would highly recommend Green Guys. Also, this was my first time using Thumbtack and it worked really well.


Tom P.

They've earned my future repeat business.


The crew cleared all gutters and downspouts of all debris and ensured that any messes were cleaned up prior to departing. They've earned my future repeat business.


Lawrence Z.

Top notch!


House and deck look brand new! Steve was professional and courteous throughout entire process. I will highly recommend his services to anyone in need of his services.


Duane D.

Great company for Powerwashing my home and patio~


They did a wonderful. Job, on time, efficient and the house and patio look great~ Would recommend them to all my neighbors and friends and the price was very reasonable!


Janet C.

Well done! The power washing met with our expectations! Thank you


Paula D.

Job went well. We were satisfied with the results. No hidden charges. Reasonably priced.


Fran T.

I needed the entire siding and large 2 level deck with railings power washed badly as my home was used as a rental for 4 years while I was out of the country. Steve and his assistant showed up on time and while I wasn't home at the time, my wife says he was very sweet and professional. When I got home I couldn't help but notice that the house and deck had been transformed to virtually brand new exterior status. I would use Green Guys without reservation for the next power washing.


Stan L.

They removed all the mold from the siding and the softwash made the roof look new again.


Ron H.

Great quality. Needed to come back. Made due on promise. House looks brand new. Willing to do minor extras no charge. You have got to call him.


Steven P.

Steve, sorry I didn't get back to you sooner. The guys did a great job. The patio looks brand new. What's even more important is that my wife, Donna is very pleased.


Thanks very much. Mike Hughes, Methuen

They were terrific. Excellent job!



Excellent. Kept us in the loop as plans changed. Work performed was excellent.



They did an excellent job. We have a two-family house, and they powerwashed the entire exterior, including the wooden porches (there are three). The vinyl siding, and some of the wood, was turning green - and they did a fabulous job with everything. I've wanted to do this for so long, and I am so glad I did!



Joe and Jake showed up with truck, ladders and power washer, after they called to let me know they were going to be about 30 min. late, which was appreciated. They were very friendly and professional, answered all questions and did a great job in about 2 1/2 hours. They also cleaned the front steps to the house for free. One of my concerns was to be able to clean mildew and dirt without ripping the paint off the wood clapboards. They were able to do the cleaning with virtually no issue. The house looks ten times better, until we plan on having it painted next year.



Excellent. Upon calling for a quote Steve came by within 24 hours and promptly provided a price. And, since we were in the process of selling our home he performed the work within 2 days of the initial visit.



These are busy guys - a little rocky with scheduling but completely understand. Steve will work with you until you are fully satisfied with all aspects of the job - including the small details. Thanks Steve - see you again.



Steve O'Neil was my main contact when I initially inquired about their services. We had a bit of trouble scheduling only because it was their busy season. But to Steve's credit, he kept me informed so I wasn't left wondering what was going on. Joe stopped by to look at the property to ensure their estimate was accurate. His visit also allowed me to ask some questions, as I never had my house power-washed before.


The work was performed on schedule and the house looks brand new--especially the roof. We has some moss growth on the roof, plus some stains from the many oak trees on our property. We also have those gutters with a shield to keep out leaves and twigs. But what happens over time is that crud that spills over tends to stick to the underside of the gutter making it unsightly. Joe did a great job and the gutters look brand new. The sides of the house look great as well and some of the green growth on the shady side of the house is gone. We have a 15'x15' concrete pad that was always a bear for me to clean each spring with my electric power-washer. But Joe had a special head and a higher pressure washer to blast away years of embedded crud. The pad looks great and I will seal it. One last thing, there was tons of pollen strings on my roof from the red oaks. They did a nice job cleaning up the pollen and making sure they did not damage the plantings near the house.


Overall, a very nice job and I'm very happy I hired this firm.



Tyler completed power washing my coastal home. The winter grit, sand and dirt was totally cleaned and the workmanship met more than my expectations. Tyler is a courteous professional representative of Green Guys. I will recommend your service to all!

Hi Steve:


I just want tell you , that you did a great job cleaning our roof at 3 Nicholas circle in Andover Ma. Last week.
I will definitely recommend your power washing service to my friends.


Thanks again,
Walter M

This is one of the hardest working and respectful service company encountered. Steve and his crew were wonderful. They notified me when they were to be arriving and did a superb job. Even cleaned up better that I had expected. They went above and beyond my expectations in cleaning my badly covered roof.

Thank you Green Guys


Kevin G.



just wanted to say awesome job, both of us are very pleased with the results. I hope you enjoyed the nutrigrain bar and the oj. Like i said you earned a customer and I'll recommend you to anybody who needs power washing. Thanks again.


Kevin R.

We selected Green Guys as one of the 3 vendors we obtained quotes from, due to their positive reviews on Angie's list. Steve was very prompt in responding to our request and his price was reasonable. Though we ultimately decided to use another vendor (through a family connection), we would definitely consider using this vendor in the future.

I wanted to take the time to thank you for a great job on power washing my house. It looks fantastic and I appreciate your attention to detail. Its wonderful to work with someone who not only does what they say they are going to do but takes the level of pride that you do in your work. I'll be passing your name out to my friends.


Regards, Linda S.

Very satisfied with the work done by Green Guys Powerwashing. Steve O'Neill was prompt, accommodating with scheduling and great to deal with. Great communication, efficient and fantastic work! Roof, house siding, front stairs and shed look like new! Would highly recommend!

Steve and his crew powerwashed our home and small shed. They did a nice job and I would use them again.

Our decks were in desperate need of a cleaning, now they can be stained. One of our decks & side of our home gets no sun, it was so green, it now looks like new. Great Job, Green Guys!

From the moment I contacted Mr. O' Neill, I was impressed by him. I e-mailed him for a quote on power washing our house and almost immediately heard back. He also followed up with a phone call. That is impressive.

The price quoted to me was well below his competitors and very reasonable for a home the size of ours (around 2300 sq. ft., two story Colonial). Moreover, he immediately gave me an appointment basically the next day. The other companies I called, particularly those from Angie's List, could not come out to do the job for around two weeks!!! So with such a great price (plus a $50.00 off coupon for a whole house cleaning on the Green Guys Powerwashing website) I booked the appointment for 1 p.m. on a Friday afternoon. Mr. O'Neill showed up right on time, introduced himself, explained a little bit about his business, and immediately got to work. And boy did he ever work!!! Within 1 1/2 hours, our home was meticulously power washed with great care and it turned out wonderfully. After he was done he took the time to show me his process and we walked around the house talking about the work. I paid him after the work was completed and I left to go pick up my kids from school. I can not recommend Mr. O'Neil and his company Green Guys Powerwashing! He might not have the biggest company, but there is no doubt that no one works harder to earn your business. PLEASE do not have any reservations about hiring Mr. O'Neill and his company. I will absolutely have him back if I need his services again.

Although we are about two weeks out from doing the job, I got a prompt response from Mr. O'Neill. He provided a date to perform the work and seems to know exactly what the project needs for successful completion. I'm looking forward to working with him.

Dana C.

The Green Guys power washed my home and scraped/painted several exterior windows.

Steve was very professional and really took our considerations into mind. His quote was by far the most reasonable and he even did additional work for us. We love how our family and dining rooms look now that Steve has painted them for us.

Justin L.

The Green Guys power washed my home and scraped/painted several exterior windows.

The Green Guys (Steve O'Neill) did an excellent job preparing my home for the market. I am an out-of-town landlord but Steve was willing to work with me and my renters confirmed that he did excellent work. Steve power washed the entire home and scraped/repaired/painted several exterior windows on my garage. Steve jumped right on the job and gave me updates as he progressed. We had some weather to work around, but Steve came back promptly and finished the job. Steve sent me text and phone updates, and sent pictures when he was done. I appreciated Steve's dedication to the job and the updates. I highly recommend his services!

Brent C.

Pressure washed house, deck, propane tanks and shed.


Very positive experience, on time and very thorough service. I would highly recommend the services.

"Steve was responsive, professional and friendly from the very first interaction, He responded quickly, got here to do the work as scheduled and did a great job. Considering the problems I have been having with other contractors not returning calls, missing appointments, etc., I think Steve deserves even more kudos! Highly recommend."

Robert A.

"Green Guy's did a fabulous job power washing my house. Steve was friendly, on time and very neat. I would highly recommend green guy's to anyone who wants a quality job done"

Alicia B.

We had the house power washed by Green Guys.

They guy was really good. It was a small company but he did a fantastic job. He was very fast and did a great job in the molds. He kept everything well protected, the vegetations and everything. He did a nice job all by himself. He was a very sociable young man and was a very hard worker. The price is good and he was careful of the greenery around your house. He was right on time.

"Steve and his crew did a great job on our house. They came when agreed to and finished the work when promised at the agreed to price.

I would recommend Green Guys to anyone with a house exterior that needs some TLC."
