  “I was really impressed with Murph, Jake, and the whole crew – they did a fantastic job! The planning and framing were particularly solid, and the overall installation was top-notch. What really stood out was how efficient they were while still being incredibly detail-oriented; they took the time to answer all my questions. I’d absolutely recommend them to anyone, especially if you’re looking at a more complex project.” report abuse

  “I can’t recommend Window HQ enough! Bill, who goes by Murph, and his team were absolutely fantastic. They recently replaced five original windows – they were from 1947 – and it was a really challenging job with older construction. Bill took the time to properly assess everything, visiting several times to make sure he understood the existing structure around the windows. When the team arrived, they were completely prepared and got the job done in under a day – a truly excellent result. I was so grateful for their professionalism and skill!” report abuse
