  • Replacement Conservatory and Windows

    10Verified Review

    Colin and his team were a delight to commission for this work, right from being prompt and accurate with the quote, courteous and responsive to any questions, and diligent, helpful and hardworking on site. They use great quality products, installed fuss free and with an eye for detail. As an older customer on her own, I very much appreciated their consideration, kindness and tidiness. I am delighted with my new conservatory and windows, and will not hesitate to recommend this company to others.

  • Replacement windows and doors

    10Verified Review

    We recently had new windows and doors installed in our home, and the entire experience, from the initial quote by Colin to the outstanding work carried out by his team, has been nothing short of excellent. Colin provided us with a detailed and competitive quote, addressing all our requirements and concerns. His professionalism and transparency during the quoting process instilled confidence in us from the start. In addition to the quality of work, the team's courteous and friendly demeanor made the entire experience pleasant.

    Harrow Windows are extremely professional. From conception to completion we can't rate them highly enough. Colin is extremely friendly, professional and very patient particularly when we had delays receiving our planning permission, as soon as permission was received the windows were fitted within the week, his team are also very friendly and professional, there was no mess nor damage to any internal decoration, a huge, huge thanks to all for a 10/10 experience and we would definitely recommend and use Harrow Windows again.

  • Replacement for some House Windows

    10Verified Review

    We required double-glazing on our house. Colin came around and went through the options that were available patiently explaining the options that were available, UVPC, Aluminium etc. After some consideration and receiving other quotes and going back and forth, we settled on Colin whose manner was very easy-going. Colin's team came and installed our aluminium windows with the minimum of fuss with ground-sheets for tidiness. The whole experience was seamless and easy and we were impressed with their dedication and skill. Thoroughly recommended!

  • New Georgian style windows and French doors

    10Verified Review

    Absolutely fabulous job. On our new extension we were worried we couldn't get the panels on our Georgian style Residence 7 windows to line up perfectly with our door panels, but Colin and Dean managed it perfectly. Very pleased. Colin also fitted the windows on the front of our house 20 years ago which still look great.

  • Replacement of Bay Windows and Front Door

    10Verified Review

    Colin and his team recently replaced our from bay windows (7-segment), front door and a few other windows around the house. We chose them based on a friends recommendation and were not disappointed. Everyone we spoke to and worked with were friendly and courteous. Timings were clear and accurate and they left the site clean and tidy at the end of each day. I would highly recommend speaking to them if you need windows or doors replacing (in fact we have already and the next people were also very satisfied).
