  Marek was fantastic – he really took the time to assess our drafty windows and didn’t try to pressure us into anything. He even gave us some helpful advice on what we could do ourselves, which was a really appreciated bonus. We’ll definitely be calling him again when we need to replace our windows in the future. report abuse

  “I was really pleased with my experience working with Marek. I hired him to replace a standard window and an old sliding glass door, and I especially appreciated that he handled the entire process – from the initial inspection and sales to the actual installation. What really stood out to me was Marek’s focus on preventing water damage, which was a major concern of mine. He immediately noticed a potential issue in the corner of the window and it was clear he was paying close attention to detail throughout the project. He also connected me with a local window company, which allowed me to get a much better price than I would have gotten from a big box store – and I felt so much more secure knowing he was taking full responsibility if anything went wrong. He was just very transparent, honest, and took care of everything. Honestly, any little hiccups we encountered seemed minor because he was so responsive and took ownership of the situation.” report abuse

  Marek was fantastic – he really responded quickly to my inquiry about a dog door for our older, custom French doors. Our house was built in 1908, and with all the unique details, it presented a bit of a challenge. He did a great virtual consultation and offered us a couple of really good options. I’d definitely recommend him! report abuse

  Mr. Window was fantastic to work with. He was incredibly transparent about pricing, the different styles available, and the timeframe for the window installation – everything was handled really fairly from the start. Because it was a rental unit, he was really considerate of both the tenants’ and my schedule, and he accommodated everything seamlessly. He was consistently professional, punctual, and incredibly tidy throughout the entire process, from the initial measurements to the final installation. I wholeheartedly recommend Mr. Window – I’ll definitely be using his services again for future window projects! If you're looking for a reliable, honest, and clean local company, he’s a great choice. report abuse

  “I couldn’t be happier with this company! From the very beginning, they were incredibly responsive – they returned my calls promptly, scheduled the estimate quickly, and kept me updated on the installation timeline with accurate text messages. But it wasn’t just their communication that impressed me; they were genuinely excellent. They were professional, really knowledgeable, and incredibly helpful. You could tell they were experts at what they do, and their efficient, no-nonsense approach was fantastic. They were also so careful during the installation, meticulously protecting my belongings and taking great pride in their work – the caulking was perfect, and the glass was spotless. I wholeheartedly recommend them for any window needs; I’d definitely use them again!” report abuse

  “I can’t recommend Mr. Window enough! They were fantastic – Mr. Window really helped me out by advising me on my Milgard windows, which were having issues with the double pane glass. He was able to determine that my windows were actually covered under warranty, and they promptly replaced the glass. It was awesome service and incredibly professional.” report abuse

  Marek was fantastic – he really went above and beyond to keep me informed about the window delivery. He not only replaced a backyard window at my house, but he also took the time to do the same for my dad, and even fixed the sliding door lock. I’m so pleased with his work that I’ve already booked him to replace three more windows at my house! report abuse
