  “I’m really happy with the work One Source Window Systems did on my home. They replaced my balcony windows and bedroom window last week, and the difference is fantastic – the noise reduction is a huge improvement. Plus, they look great and are really easy to use.” report abuse

  “We recently worked with OneSource on a big rehab project – we replaced almost 50 windows and were so impressed with their service. Bill and the team really took the time to understand our needs and budget, and they helped us find the best, most affordable high-efficiency windows. They were professional, knowledgeable, and, importantly, they delivered the job on time and within our budget. I’d definitely recommend OneSource.” report abuse

  “Overall, I was really impressed with the service. They offered excellent communication and a fair price – definitely a big plus. While I often handle repairs myself, it was clear this team has the expertise and equipment to do the job right, and I knew I was getting a professional installation.” report abuse

  “I was really pleased with One Source’s team – they were incredibly professional and got right to work, staying focused until the job was completely finished. They did an amazing job with our six large glass doors, and the windows look fantastic! I’m so happy with the results and would definitely recommend them.” report abuse

  “The windows themselves are really good, which is why I was so hopeful. Unfortunately, the customer service was shockingly bad. I’ve been waiting over a month for someone to come and fix the issues – a piece is missing from my bedroom window and the patio door isn’t working at all. It feels like once they’ve taken my payment, they just don’t care anymore.” report abuse

  “I can’t recommend One Source Window Systems highly enough! Angelica and her team were fantastic – incredibly punctual, friendly, and they did a really professional and efficient job replacing my windows. If you live in a condo community and need window work done, definitely call them and ask for Angelica!” report abuse
