(This review includes a response to the business owner's reply)…read more I had a deeply disappointing experience with Paul's Windows, and I want to share it so that other homeowners know what to expect before working with this company. I reached out for a small bedroom window replacement and had one key requirement: that the new window, once installed, provide a minimum clear opening height of 13 inches. The sales associate, Art, confirmed via text that the manufacturer (Crystal Pacific) said it would: 13.1875", in fact. That was fine by me. But when I asked for that specification to be confirmed in the contract, in writing, Art refused. Let me be clear: I wasn't asking for a personal warranty on the product. I simply wanted confirmation that the installed window, as ordered and managed by Paul's Windows, would meet the functional requirement I had clearly communicated. Art repeatedly deflected, referring to "what the manufacturer said," but was unwilling to take responsibility for the result. When I asked for accountability, he became dismissive and eventually walked away from the job. I contacted Paul directly, hoping for a more professional response. Instead, I received a generic brush-off and a claim that the window wouldn't meet the specs, which contradicts what their own sales associate had already confirmed. Worse, Paul didn't acknowledge or engage with any of the valid concerns I raised around basic customer service, transparency, or professional responsibility. Ultimately, I wasn't asking for anything unreasonable. I was hiring a company to manage a job and deliver a specific result. If something went wrong, say, the manufacturer provided a window that didn't meet the spec, it would be on the contractor to resolve it, not on me to go chase down the supplier. That's what any responsible company would do. But Paul's Windows made it clear they don't see it that way. If you're okay with vague communication, contractors who won't stand behind their own work, and potentially being left to deal with problems on your own, maybe this company is fine. But if you want clarity, professionalism, and accountability in writing, then look elsewhere. § Paul's response below is a classic damage control move -- polite on the surface, but full of deflection and quiet rewriting of events. To clarify: the window in question would have met the required 13" clear opening. That wasn't in dispute. Art, their sales associate, confirmed that in writing and was fully prepared to proceed with the job -- until I asked for a simple written accountability. That's the moment everything fell apart. Paul's follow-up misrepresents the timeline and sidesteps the core issue -- not whether the window would fit, but whether the company was willing to stand behind the result they were being paid to deliver.

Jon, the owner, was amazing to work with throughout the whole project. He was responsive, honest, patient, and made sure everything stayed on schedule and ran smoothly. You can tell he genuinely cares about his customers and takes pride in the quality of work his company delivers. The installation crew was also fantastic -- professional, respectful, clean, and detail-oriented. They showed up on time, protected the house during installation, and paid attention to the small details that really matter. The finished product looks incredible and completely elevated the look of our home. What really stood out was the communication and overall customer service. There were no surprises, everything was explained clearly, and the entire experience felt stress-free. It's hard to find companies today that combine quality workmanship with great customer care, but Frontier Windows absolutely delivered. Highly recommend Frontier Windows, Jon, and his team if you're looking for a smooth, professional window installation experience.

The door was hard to slide, didn't seal properly, and clearly needed more than a quick repair. From the first visit, the team was straightforward and honest about what could be fixed versus what made more sense to replace. No pressure, no upsells. Scheduling was easy, they showed up on time, they worked clean and efficiently. The install itself went smoothly, and the difference was immediate. The new sliding door glides effortlessly, seals tight, and feels solid. No rattling, sticking, or gaps. Communication was great the whole time: they explained the issue clearly, walked through the replacement options, and followed through exactly as promised. If you're dealing with a sliding door that's past its prime and want it handled right the first time, this is a company you can trust.

Marco and his team came out on 3/18/2026 and installed the door and window they did an excellent job. I waited for a few weeks before leaving a review, it had rained for a few days a 2 weeks ago so far so good and No leaks.

It was difficult for me to find the repair service, and I am glad I found MJ'S Windows To fix my vertical sliding window, they needed to purchase new sliding parts.

I like that MJ's gives you the option of repair or new installation without commercial pressure. I will definitely contact them with a new project in the future.

I truly cannot say enough amazing things about this company. I came in hoping to replace both my…read morebedroom windows and the sliding door in my living room, and from the very first interaction, I was met with nothing but warmth, honesty, patience, and professionalism. Nan was the one who initially educated me in the office, and she was absolutely incredible. She took the time to walk me through everything, answered all my questions with so much clarity and patience, and genuinely wanted me to understand what would -- and would not -- solve the issue I was experiencing. Her knowledge and care made me feel respected, informed, and never pressured. What completely blew me away was the honesty. Despite being more than capable of selling me new windows, they were the only shop that told me the truth: the change I was hoping for couldn't actually be achieved through window replacement alone. That kind of integrity is rare and speaks volumes about this company's values. Then there's Roy -- one of the owners -- who personally made the journey out to my home to further educate me. The fact that an owner would take the time to come out himself, explain everything in person, and make sure I fully understood my options is something you just don't see anymore. He was thoughtful, thorough, and incredibly generous with his time. And yes, fair warning -- Roy looks like he walked straight out of a magazine. Be prepared to be completely stunned by the presence of an actual god while receiving some of the most honest, professional guidance you'll ever get about windows. Even though they didn't make a sale this time, Lion has earned a customer for life. I will absolutely return for all my future window needs and recommend them to friends and family without hesitation. Please don't ever change, Lion. Whatever you're doing is working beautifully. Everyone was so kind, genuine, and knowledgeable. Huge gratitude to Nan for her education and patience, and to Roy for going above and beyond by coming to my home. I can't recommend this company enough and wish them nothing but continued success.

I only had a month and I contacted several window companies for an estimate. 1) I compared Milgrad prices with Lion to Home Depot and theirs was cheaper. And also 2-3 weeks faster. Ditto other window companies on Yelp. 2) Very efficiently run. I had my measurements quickly within a day since they knew I was in a rush. I got my windows just in time installed with one week to spare. Installation was quick and easy and took 2 hours for 2 windows. They were fast on communication via email which I love. Also providing me updates constantly. I highly recommend them for window service.
