    I am an architect, with demanding standards when it comes to craftsmanship, attention to details and general manners when installing in a lived in home.Traditional Window & Conservatory Company were impeccable in all respects and pleasant with it.

    Mr Egrett

    2 years ago, we had 10 new wooden sash windows made and installed. 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.

    Mr Talbot

    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

    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


    Fantastic service from Des, Gary and all the team and the windows are superb. They have made such a difference to the warmth of the house. Our initial purchase was for an extension, now we are looking at replacing them all! Would highly recommend.

    Mrs Coulstock

    Despite the long wait for planning permission to be granted, the personalised customer services; standard of craftsmanship and the efficiency of the work carried out by the team of fitters has been excellent.

          Mrs Wilson

    Efficient, faultless service with a high quality final product. Will definitely be using again!

    Mr Guiu

    We are extremely happy with the service provided from the initial visit to the installation. The Staff who installed the windows were extremely considerate to the fact there were young children in the house and left the place spotless. And the windows look fantastic!

        Mr Walker

    The Installations came promptly at 08:15 and had finished both windows by 14:00. They did a great job with no damage to the internal decorations. The windows are a perfect match satisfying conservation requirements. We are looking forward to warmer bedrooms this winter.

    Mr Conroy

    We have had four Box Sash Windows fitted by the Traditional Window & Conservatory Co. Two have been in place for about five years and are still in excellent condition. The other two were installed on 27th June 2018. The installers worked cleanly and efficiently and did a great job with no damage to the surrounding decorative finish. Overall this was very impressive work.

    Mr Rowe

    From the outset Gary was knowledgeable & honest in what we needed – Patio Doors. On this advice we agreed the contract & had the doors installed. They arrived on time and completed the work to a high standard. We are delighted with the new doors.

    Mr Gadsden & Mrs Jeffers

    Great service from beginning to end. Great to see everything left so clean and tidy at the end.

    Mrs Inch

    We are delighted with our new windows, a prefect match for the originals but a huge improvement on the draughty frames and rotten sills. The whole experience went smoothly with care and attention paid at every stage. I’m so pleased we decided to do this, the house looks so smart now.

    Mr & Mrs Gronmark

    We are so pleased with our new windows. The workmanship, attention to detail, final finishing and cleaning up were wonderful. Great workers too! Thank you.

    Mrs Chapman

    This was a complex job, cleaning 2 Edwardian leaded glass panels and enclosing between 2 new sheets of glass and sealing so that it became triple glazed. The finished job looks superb, the old glass and leads look like new and the quality of the workmanship and finish is excellent. I would highly recommend the team!

    Mrs Harford

    Occasionally one experiences a company that takes all the stress out of conducting home improvements. Traditional Windows are thoroughly professional from producing designs that we were happy with through to site survey and installation – all conducted with the minimum of fuss. When the installers had left, I found myself looking around the house to see what else they could replace!

    Mr Carrigan

    I would highly recommend TWCC. The staff are very friendly, the products are of really good quality and the fitters are quick, skilled and leave the place clean & tidy. Any problems with a handle is fixed quickly free of charge up to 10 years after fitting – no quibble. Excellent service all round.

    Mrs Atkins

    The Traditional Window & Conservatory Co. recently installed a beautiful window they manufactured for our 1825 flint cottage in West Sussex. The window is very well designed and made, matching the other windows perfectly – the installation and company were smooth & very professional.

    Mr Palmer

    We are delighted with our new windows that have been manufactured identically to those being replaced – an absolute must to meet the planning consent. I cannot recommend more highly.

    TWCC are excellent – they are professional and charming with it. They seem to be able to overcome problems and just go the extra mile. A company that provides still a service.


    We are absolutely delighted with our windows and doors and believe they will prove to be a valuable enhancement to our home over future years. We were particularly impressed by the speed, efficiency and attention to detail in the way the installation was undertaken, and by the courtesy shown to us by the whole team.

    Mr Cave

    We used the Traditional Window & Conservatory Company to replace four box sash windows, two in 2013 and two in 2018 nd were very happy with the results. Recently we had a box sash bay window replaced by them and again the skilled fitters did a great job on the day of installation. They work in an exceptionally neat and clean way to avoid any damage to surrounding decor. When our old bay window was removed some bricks above came away unexpectedly due to a rotten support timber. The fitters took a lot of care making good after this; they restored some plaster moulding above the window at no extra cost and came back the next day to touch up paintwork. We are very pleased with the new bay window.

    Mr Rowe

    We are absolutely delighted with our new windows. The fitting procedures were expertly conducted, in an impressingly prompt manner, and by capable and considerate craftmen. An excellant service provided which we can confidently recommend. Thank you.

    Mr & Mrs Hulme

    This is the second time we have used this excellent company. The work is done efficiently to a very high standard. We highly recommend them.

    Mr Hosken

    We had our new front door fitted recently, it doesn’t disappoint, the original panels (framed glass) were restored to perfection, just transforms the front of the house. We also had our original Victorian patio doors replaced and painted externally to match the contemporary doors and windows in our kitchen – perfect again. The people that fitted them were excellent, friendly, fast and cleaned everything after.

    Mr Odle

    Delighted with the Sash Windows recently installed by TWCC. The installation was efficient with an excellent finish with attention to detail.

    Mrs Darlington

    I would like to say that we are all delighted by the windows, they have made an immediate improvement to our property (my daughter has just told me how good it is to see out clearly) and inside the house is warmer and quieter.  Replacement was long overdue and for me it is a great relief not to have to worry about the condition of the paintwork or wood rot.  We really appreciate the attention to detail in that the new windows are almost an exact copy of our originals and so fit in with the age of the building – an excellent job. Finally I would like to commend Gary, Anthony and Marlon on their workmanship for the installation – they did an excellent job with a minimum of disruption and it was a pleasure having them in the house whilst they did their work. All in all deciding to use Traditional Window for this work was the right one and I am very pleased that is has completed so successfully.  It has been the best investment I have made on our property in a long time.  

    Mr W Hall

    The Traditional Window & Conservatory Company have provided an excellent service from its time of our initial contact with them to the completion of work on site. The site team were particularly good, polite and considerate.

    Mr Hynard

    Our original windows were over 100 years old and looking tired. The new ones not only look better, both inside and outside but have the added bonus of:- No draughts and so much warmer. Noise reduction is amazing. Beautifully made, expertly fitted, we are very happy.

    Mr & Mrs Sharman

    Over a number of years we have progressively replaced all of our old windows with new windows provided & installed by the Traditional Window & Conservatory Company. There can be no greater compliment to the company than that we have repeatedly returned to it for further windows over so many years.

    Mr Blackburne

    The advice, the manufacture and the fitting were all of the highest standard.  The five sash cord windows installed operate perfectly and are beautiful. Our thanks to everyone at Traditional Window.

    Mr Davies

     Over several years I have used Traditional to replace most of the windows in my Edwardian home. The windows are of very high quality as is the service. I can highly recommend them.

    Mr Blythe


    Living in a strict conservation area as we do, it is always difficult to get alterations or modifications to a property approved by the relevant local authority, as well as the local conservation society whose objective is to ensure the highest standard of conservation possible. Having already lived in our area for over 40 years, we became very much aware of the standards to be met. For some past years, we followed the work the Traditional Windows company undertook with the approval bodies concerned, in order to meet the stringent and detailed window specifications required to achieve satisfaction. Having down-sized to a smaller house on the estate, we decided to have the entire house of windows and doors replaced with new, double-glazed and more environmentally friendly, units. Traditional Windows’ quotation for the work included full measurement, drawings of individual windows and doors, the planning application, removal of secondary glazing, monitoring factory production, removal and replacement of all windows and doors and much more.   They kept us fully informed along the way. The finished job was fantastic and exceeded our expectations.   We continue to receive compliments from neighbours and passers-by.   A job well done!

    Keith & Ruth Hall


    Delighted with the strained glass door & French windows which were matched meticulously to the original Edwardian design. The workmanship was excellent & the staff who fitted the doors were friendly and efficient. We are in a conservation area so it was important to have the original design – I have received many compliments from neighbours on the quality of the doors. I am happy to recommend this happy. Thank you for completing the job over this difficult time.

    Mrs Flynn

    Thank you again Gary for another very efficient & excellent service. Again two very hardworking members of your team came & were very pleasant to have around. I would highly recommend your company to anyone wanting to replace windows.

    Mr Hosken


    We were very satisfied with the quality of the window and the services provided by the Traditional Window & Conservatory Company. The window looks terrific, its very sturdy and works perfectly. The installation was very efficient and the room was left spotlessly clean. We highly recommend.

    Mr Rattigan

    I am very happy with the installation. The team were exceptionally tidy, and finished the windows to a very high standard. So much so, it already looks like the windows have been there for years! My neighbours have also commented on the quality.

    Mr Young

    Our new large bow windows has been well made and meticulously fitted by Traditional Window & Conservatory Company. They acted responsibly throughout and produced a high quality result.

    Mr & Mrs Palmer

    Well worth the wait…Due to pandemic issues. Excellent workmanship & efficient installation.

    Mrs Downer-Wills

    The very high quality of workmanship made up for the protuacted waiting time. On our recommendation our son has signed up to have all his windows replaced by you!

    Mr Mclean

    We have now completed two projects with Traditional Windows, the first 13 windows for two bedrooms & our living room, the second two dormer windows for a loft conversion. All hand made to fit our very particular Conservation Area, beautiful construction, finish and fitting. Well worth the wait. Looks amazing.

    Mr & Mrs Sharman

    Over the last few years, we have used the company to replace all our windows as well as two external doors. They have always been a pleasure to deal with and take a justified pride in the quality of their work. They may not be the cheapest but they represent excellent value. They never cut corners and we remain delighted with the results.

    Mr Hooper

    We have had Sash and Casement windows installed by the Traditional Window & Conservatory Company and we have been consistently impressed by the quality of the workmanship, professionalism of the design and installation team and level of service provided. The fact that we have returned for installations at least four times should speak for itself. Thank you!

    Mr Streeter

    In 2018, the Traditional Window and Conservatory Company fitted bespoke double patio doors in my kitchen. The quality is superb, everyone involved was really helpful and the whole process was so easy. I have also used them to replace 13 sash windows and once again their service was top notch. Quick, clean, friendly and professional. I can’t recommend them highly enough.

    Ms Manley

    Traditional Windows has undertaken three contracts for me over the last 10 years. The workmanship on each occasion has been excellent and I would be willing to recommend the company to anyone wishing to replace defective windows in identical style.

    Mr Garnett

    Traditional Window & Conservatory Company did an excellent job replacing two Sash Windows. The quality is very high and the room concerned is now much warmer. The fitters were efficient and pleasant. We are very pleased.
