Quick Installation, Great Looking Windows

The customers services was very good from start to finish. My installation date was pushed back 1 day on the day before the installation, which was short notice, but I was able to accommodate this. The fitters were friendly, quick and clean. My windows were replaced within the time agreed and they look fantastic. Very happy with the quality of the product and the service. The only minor point is that the making good (painting) to my white pebble dash exterior wall has to be done my me. :/ Such a specialist service, taking into consideration the cost of the works/windows, should include a full making good service also. That would help to put the company above others (think Amazon). Nevertheless, I'll have to now get some paint and make good the areas myself. Other than that though, thumbs up!

There are a wide range of double glazing options from upvc to aluminium to wood then for wood there are mass produced factory made options to complete bespoke products made by small joinery companies. Where The Original Sash Box Co sit is in the wood category between mass produced options (which lack the details you may want to keep) and a small joinery option which are expensive and may fall short when it comes to installation. Sash Box aim to give you a bespoke product but at a competitive price. It took me a while to get to this conclusion but without question if you have period house or live in a conservation area or just want to maintain the features of the original windows then this company are the people to speak with. On the sash windows I kept the original boxes their sashes are designed to fit within these still with double glazing. I also bought a complete replacement for french doors and side windows, the product is first class as is the installation and service. Was worth the investment.

We are highly satisfied customers of the Original Box Sash Window Co, on three separate occasions now. The most recent work carried out to replace old windows was another example of great customer service they provide, by a friendly and highly experienced fitter, who took great care with his work, ensuring our property was left clean and tidy. Work started when expected, and finished on time. We also received excellent customer service for the sales aspect - helping us to determine the exact window specifications needed. The windows installed are of excellent quality and finish. Would highly recommend.

We are very happy with the 9 windows which have just been installed. They look very good and feel robust. The installer did an outstanding job, always on time and tidy, and well organised, minimising disruption around the house. We ordered these replacement windows from Envoygate (The Original Box Sash Windows Company) having previously replaced some other windows and French doors and having found their product and service second to none. They are a little more expensive than others but we believe they are good value for money given the quality of the product.

Great windows. My only regret is that I can’t afford more of them. This is a good, honest and hardworking company. Values that are shared by all of the staff I have dealt with including the fitters. I’ve bought 10 new sash windows, in 3 batches over the past 5 years and can’t find fault. I think you’d be hard pushed to find a better company or product.

We have recently had 11 windows replaced by ‘The original box sash window’ company and we are extremely happy with the result. Right from the first contact the staff were very professional and helpful. The replacement windows are exactly the same as the original windows in all respects, except of course they are double-glazed. The fitters did a fantastic job and left no mess once they had finished. We would recommend ‘The original box sash window’ company, to anybody who is thinking of replacing old single glazed sash windows.

The Original Box Sash Window Company renovated my sash window boxes, and replaced the sashes windows with similar Georgian style double glazed units in keeping with the Conservation Area conditions. The windows are very high standard, well-fitting and draught-free. Such a difference, and so quiet..

Good quality work, and excellent outcome in the end, but needed a little push to meet the required finish standard at one point..
