CNS Wooden Windows & Doors

"We had a great experience with CNS Wooden Windows & Doors. They did an excellent job restoring and installing our timber windows while preserving the traditional look we wanted. The quality of the workmanship is outstanding—the windows are solid, operate smoothly, and the drafts we used to have have completely disappeared. What really stood out was how clearly the team explained everything throughout the process, making it easy to understand our options. The improvement has been noticeable from day one, and it's something we appreciate every single day. We're very pleased with the results and would happily recommend their services."

"Took us a while to pick someone for the sash window job. Got a few quotes and theirs wasn't the cheapest but the bloke who came to measure actually knew what he was talking about. Install took two days, kept us updated throughout, and the finish on the wood is exactly what we wanted."

"Had all the sash windows replaced across the front of our Victorian terrace and the difference is remarkable. The new frames sit perfectly in the original openings and the proportions match the period style of the house, which was really important to us. Everything just looks right - the glazing bars, the way the sashes line up, you can tell these weren't rushed. The big thing for us though is how smoothly they actually open now. Our old ones were painted shut or jammed half the time, and now they just glide. We spent a while searching around London for a company that properly specialises in timber windows and CNS kept coming up, so we went from there. The draught proofing they put in has also made a real difference on the ground floor where it used to get cold. Painted finish looks great from the street too."

"CNS Wooden Windows & Doors did a very solid job on our timber windows. They kept the look we wanted. The windows feel sturdy, open properly, and the drafts we had before are gone. I also liked that they explained things in plain language. This is one of those jobs where you notice the difference right away every day."

"We highly recommend this company for any wooden window needs. They were very thorough with the measurements and kept the site tidy. Very skilled and reliable carpenters throughout."
