"Impeccable service! Mr. Gagné Côté is meticulous and professional. We have used several companies to clean our windows, and this is the first time I have been completely satisfied with the result. Mr. Gagné Côté works very cleanly, the screens are impeccable and the windows are spotless. I recommend him without reservation."

Coralie Loblicq, Town of Mount Royal

"I had the windows of my condo washed by Entretien EXT, and I was extremely satisfied with the quality of the service they provided. Courteous, knowledgeable, on duty, their customer service is second to none. No residue in the windows and no post-wash slides. Honestly, it is the best washing service I have had since we had our windows washed in our condo building."

Carl Dubuc, Le Plateau-Mont-Royal

"Great experience with David. A real perfectionist and my windows were sparkling when he left, as well as my house. There was no mess or water anywhere He did the entirety of the window, inside and out, thresholds and screens. Also very polite and respectful, always removed his shoes! I highly recommend him and his team!"

Rosemary Pal, Sainte-Adèle

"We are very satisfied with David's work on the front and back of our condo, as well as cleaning the front gutter. Beyond his efficient work, he also made sure to clean the stairs in front of our building. David knows what he's doing and took the time to explain his process. He was also super friendly. I highly recommend his services."

Tomokazu Le, Rosemont–La Petite-Patrie

"Excellent and fast service. I was not at home when the worker came by, but I received photos of the clean gutter and, in addition, photos of a section of the roof that we suspected was leaking, which he kindly agreed to photograph for me. I highly recommend him."
