The Original Box Sash Windows CompanyArvostelua 

We had researched many sash window companies prior to placing our order with The Original Box Sash Window Company however the initial consultation we received from Mike and the glowing reviews sealed the deal for us. We have had 6 windows replaced in our house and the quality of workmanship, product and improvement both in terms of noise and heat insulation has been immense. We were very impressed with the personal, professional level of service and the speed in which installation was book and carried out.
Highly recommended!

We got our Original Box Sash windows fitted last Thursday and Friday by Simon. He did a fabulous job and we are pleased with his work and with the quality of the windows.

The entire process, from the initial meeting with Micheal, progress reports by Phillip, and the fitting by Simon, were professional and to a high standard. Tanya was very easy to work with both in scheduling and when it came to settling the invoice.

The house is finally uniformity warm and draft free. We've lowered our thermostat by 5 degrees. I wholeheartedly recommend The Original Box Sash Windows Company for its excellent service and quality of windows.

We would highly recommend The Original Box Sash Windows Company. The whole process ran very smoothly, from initial visit and survey through to the fantastic installation team who were friendly, tidy and efficient. Our new windows have been much admired.

We couldn't be happier with the result of our new windows. The house is warmer and quieter. More importantly, though, we would like to highly recommend this company for the quality of their customer care and especially for the expertise of the fitting staff - the job was done utterly efficiently, with minimal mess and the finish was immaculate - real master craftsmen.

We used Original Box Sash following a work colleague recommendation. Thoroughly recommend them, and have done so several times to friends (who have in turn been delighted with their work).

We had three very large bay windows replaced with triple-glazed sash, and 3 other single-sash replaced too. All personnel we met were fantastic and professional. No pushy "sign now to get the best price" treatment (unlike others who quoted) and we got a quality product that - almost 3 years later - still looks like new. Plus it is British-made, if that is important to you.

The improvement in terms of room warmth was immediate and noticeable.

Honestly one of the best 'investments' we have made.

My partner had some replacement double glazed sash windows installed by The Original Box Sash Window Co in her house in Fulham. Now we have moved away from there and I have just ordered a set of windows from them for a flat I own. I expect that they will be same flawless quality as the Fulham ones were. Nice straightforward people to deal with as well. I've rather given up looking elsewhere.

Everyone was very friendly and helpful and I am delighed with the windows/
I live in a conservation area and the windows had to exactly match the specifications. And they do

We had a very positive experience with this company. Their service was efficient from start to finish, and the window are very sturdy and appear to be well made. There is certainly less noise from the road and it's warmer inside the house. Would recommend them.

OBS is not the cheapest supplier but, having shortlisted three firms, I decided to use them again. I had used them many years ago in a previous house and been very satisfied. Thei service is excellent and flexible, the people are very helpful and the installation process is efficient and painless. Everyone is professional and meticulous whether in advising on what is best, measuring up and actually installing. Simon and Thomas were very tidy and cleared up after each day. Steve Ryan has been very good in following up the order from paperwork to manufacture and installation. He came and inspected after installation and the company was good about fixing minor items. Last but not least the windows are very well made and fit the existing frames beautifully and look like the original ones. In short an excellent firm.

We had installed sash windows some years ago and they remain in good shape. More recently "dormer" type windows have been installed and these are very satisfactory. They offer insulation as for the sash windows and also enhanced security which is an added feature which is important. Maintaining the windows is relatively straightforward and it is expected that
they will continue to give us the satisfaction which we had sought.

The four façades of our Victorian house face midway between the cardinal points of direction, and most of our windows face the two streets which accost the house on the SE and the SW. The house is exposed on these two sides to every sort of weather, which is why it is called Sunnyside. Three years ago, wishing to improve the insulation of the kitchen and the drawing room, we had the Company replace the sashes with their beautiful hardwood triple-glazed sashes, which fortunately could be fitted into the existing boxes, which were sound. A year later we were in a position to do the same for all the other windows on those two sides. This represented a colossal investment for us, but was certainly worth it and now we have perfect insulation, no draughts, and superlative windows that fit..

We replaced 1970s uPVC windows in the front of our London terraced house in 2010. The Box Sash windows looked great from the day of installation and still look perfect today. They are attractive, secure and have improved visibility and sound-proofing. I am sure they have enhanced the value of our home. Delivery was on-time and installation was perfect. I would strongly recommend them.

We have used Original Box Sash Window Company twice. Most recently they refurbished and upgraded our existing box sash windows to double glazing. Everyone we dealt with was helpful, friendly, professional, and very good at their jobs. The quality and attention to detail in their work is excellent. Would definitely recommend them.

Not so expensive - just excellent value
The sash windows are of superb quality, absolutely faultless. The two fitters who came to put them in were very thoughtful in caring for the carpets. All carpets involved were covered in sheeting and the staircase also. Shoes were removed as soon as they came in the house. The finished work was perfection and the two fitters absolute craftsmen. Any dust afterwards was vacuumed up.

I cannot fault the overall service from Box Sash Window company. I was contacted immediately with an initial estimate and this was followed up with a visit where everything was discussed. The job was completed to my timetable and the window fitter did a superb job quickly and efficiently. You get what you pay for. This is a high end product from a high end company.

Our flat is in a Mansion Block built in the early 1900's and the windows and doors were in poor condition and there was considerable heat loss and a great deal of traffic noise. The difference is stunning and we now reduce the CH to a few hours per day whereas before we needed heat all day and noise is a thing of the past.

We were a little bit concerned about changing our original box sash windows for double glazed windows, as they are a very important part of the character of our house. So choosing a company that could retain as much of the original feel of the windows was very important to us.
The Original Box Sash Window Company were superb from start to finish we felt in very good hands, everything happened when they said it was going to and we were very happy with the end result (very well insulated windows, with no condensation or noise issues and that keep the original feel of the property) Several friends have commented that they would not have noticed that we changed the windows if I hadn't mentioned it.

Great company and I would highly recomend to anyone contemplating changing their original sash windows

We have had all the windows at the back of the house replaced and the kitchen bay rebuilt by The Original Box Sash Windows Co. From the first visit, to the surveyor's visit and the installer arriving everything went perfectly. They may not be the cheapest but they have to be the best around.
