Customer Satisfaction
Our customer satisfaction is highly important and the reason we offer a comprehensive service from the initial, unique survey report right through to the hand finishing of the installation.

Many of our window and door installations are the result of additional orders from our satisfied
customers together with recommendations to family and friends.


“2 years ago, we had 10 new wooden sash windows made and installed on the rear and side elevations by The Traditional Window and Conservatory Company, this was after initially approaching 10+ companies and meeting up with 3. As I type this they are back at our house replacing the whole of our front elevation being 4 sash and 6 casement windows, so as you can tell we think their windows are great …. PS I am a Chartered Surveyor and would not recommend lightly. “

“From day one TWCC were impressive providing sound advice and a detailed quotation with options. Their products and quality workmanship are second to none and their fitters are highly skilled and leave little mess behind. Keep up the good work – our house looks better and is much warmer!”.

Mr Vasdekys, W12

Thank you for creating and installing such good quality windows to meet our ever-changing designs. We are very happy with the results and are already recommending you to friends and family”.

Mr Rock, N10

“I had delayed replacing the original windows to my Edwardian house as I feared losing the fine detail and elegance, but The Traditional Window & Conservatory Company were the answer!. They replicated the exact appearance of the original windows–but what an improvement to both the heatand sound insulation!!. I am delighted! The company employees and representative were also polite,helpful and efficient. Thank you”.

Ms Campbell, TW1
