Reviews of local pros in Coventry, Rhode Island

I called a few companies for quotes on my house , sheds and deck. Tom came out right away and was beyond professional and knowledgeable. His pricing is very reasonable. Not only did he take care of the house deck and sheds, he also did my patio and my K9 grass and everything came out better than I had expected. I would highly recommend Knockout Power-washing to anyone. I will absolutely use them again.

Absolutely exceeded my expectations!! From coming out on time to give me a very reasonable quote for cleaning my 3 story home including decks - my home was so in dire need of an exterior cleaning! I was nervous about residue spots on my windows for no reason, they look amazing! Definitely recommend this company!

Tom and his partner did an amazing job on my house, deck, and fence. He spent close to 2 hours cleaning. I can’t praise his company enough! Give them a try, I promise you won’t be sorry. 🏠🚿🧹

Timely, professional and meticulous. We purchased a large property with multiple buildings that needed attention. Tom brought these buildings back to life, the before and after are insane. Highly recommend.

Great company! Tom was quick to respond. He showed up on time for the estimate and the job with good communication in between. He did a great job with the moss on our roof and washing the sides of house and deck! They look wonderful. I highly recommend him.

Tom and his crew did a fantastic job power washing our front walkway and steps. It came out looking new!! Would definitely hire them again.

Knockout did an amazing job cleaning our roof, siding, front and back deck. They walked me through everything they were going to do when they quoted, then they showed up on time and did the job exactly as described. We're especially blown away by how great the back deck looks, I've never seen it this clean! Highly recommended - we'll definitely call them again in future.

Tom did an outstanding job of cleaning the house, windows, railings, doors and the outside of the gutters. Best house cleaning we have had by anyone and so easy to deal with. We would highly recommend them. This was our first time using them but will not be the last

Tom went above & beyond!! Very professional &. Curious!! We had some bad staining on our chimney & he go 98% of it off. Very happy homeowner!!

Knockout Powerwashing did a great job! My white vinyl siding and fencing along with deck look absolutely amazing! The wood deck railings and posts look brand new! Tom was knowledgeable of which products to use on vinyl siding versus wood to avoid any damage. Upfront cost was provided and held to. Overall, very personable, showed up on time and got the job done in one day. Highly recommend Knockout Powerwashing!

Tom was awesome, very friendly and was very professional. He did an awesome job. Very happy customer! If you’re looking for a reputable company for your power washing needs give Knockout a call!

We had 2 houses power washed yesterday. What. A beautiful job. Can’t thank them enough. We has a chimney that was full of dirt and rust they got it all up. Tom you are the best

I called several house power washing companies and Knockout was the only one to return a phone call. A friend recommended them so I meet with Tom. He was on time and very carefully explained how he was going to clean my house. NOT power washing, soft wash. Power washing could damage my siding. Next explaining how he does it and then I scheduled a time for him to clean my siding.
He texted the day of the cleaning letting me know he would be at my house at 10 AM. At about 930 he texted me to let me know he would be 15 minutes late. What a courtesy, you don't get that kind of attention very often.
Tom showed up and watered the few plants that were up as not to have them subject to the cleaning solution. We didn't cover them because the flowering had gone by. I left him to the work. I had to take down several items attached to the house as not to damage them and off he went. The house and fence had green algae from our very wet spring. After Tom completed the wash he walked me around to make sure everything was ok.
The house was sparkling clean I did expect it to come out so nice. In a couple of years I will be using Knockout Powerwashing again. He did a GREAT job.

I recently had my house power washed, and I couldn’t be happier with the results from start to finish. The experience was outstanding. The team arrived promptly at the scheduled time and immediately got to work, taking care to protect my landscaping and outdoor furniture before beginning. Their attention to detail was exceptional.
Years of dirt, grime and pollen were no match for their high-quality equipment and expertise. They meticulously cleaned my siding, driveway, porch, and even the walkway making everything look brand new. The difference is truly remarkable. My home has never looked better.
The crew was not only professional, but also courteous and respectful of my property. They took the time to explain the process and answered all my questions thoroughly. I appreciated their transparency and commitment to exceptional customer service.
I highly recommend this power washing company to anyone looking to restore their homes appearance. Their work exceeded my expectations in every way and I will definitely use their service again in the future. Thank you for making my house shine!

Knockout Powerwashing was incredible. Tom was quick to come out to give an estimate and quick to get an appointment for the service. I got several quotes and Tom was very reasonable AND he included windows which many other companies charge extra for. He showed up on time and did an excellent job removing the mildew on our house. Will definitely be a repeat customer.

I had an appointment that was confirmed with an email and they never showed up. I waited for 45 minutes, texted and left a voicemail and they never got back to me.

This guy is a joke... should not own a business charges 1500 to remove mold but yet it is not gone used an excuse that it should go away in a week to contact him if it is not... so I do so and he says he will come out to use the spray that he should of used in the first place and never shows up I call and call an text and text and he doesn’t respond.... horrible business owner and should be ashamed you are a scam artist and that is all

We used Jennings All Spruced up for mold remediation treatment on our basement, Mike did a great job and basement is looking and smelling so much better!

Great work by Jennings! They arrived on time and worked for 3 hours. I had upholstery and carpeting (including stairs) cleaned. Everything looks great! Thanks for your hard work!

Mike was extremely professional and very reasonable...I called over 7 places looking for a good price to have the mold removed from our attic and Mike had the best prices. His equipment is brand new and works great! And they did a phenomenal job on my attic.

Mike and his team are amazing when it comes to their trade. There are always on time and extremely diligent in their practice.

Mike is the first person I’ve ever seen actually clean the inside of paper towel dispensers as well as the heating tray under the oven.

I would highly recommend them for any custodial/janitorial services for your business/personal needs.
