North London Box Sash Opiniones 

A beautiful new wooden box sash window for upstairs bedroom, made and installed by Mark and his team. Very efficient service. Arrived on schedule. Installed and painted in less than a day. Everything cleared up thoroughly. I am very pleased with the work.

North London Box Sash provided the ultimate finish to our major house renovation. Our new double glazed sash windows fit seamlessly into the original Edwardian boxes. They look and feel like perfectly restored originals. Inside, the warmth and silence are evidence of their fantastic quality.

Great quality work, excellent customer service and competitively priced. We will certainly be using North London Box Sash again!

Mark and his team did a great job and we wouldn't hesitate to use them again.

They replaced three sash windows in our 3rd floor flat in under two days.

They were friendly to have around, protected our furniture and floors well and cleaned up excellently at the end.

Mark and his team were excellent, gave a competitive and very clear quote, squeezed us in before Christmas by working over a weekend, arrived on time, carried out the work professionally, were extremely considerate and tidied up after themselves daily so that it was impossible to even know they'd been working. The results are excellent and have made a significant difference to our comfort in our home. I would use this company again, and would recommend them, without any hesitation whatsoever. They are literally amongst the best tradespeople I have ever dealt with. I hope they go from strength to strength as they have the best approach to doing business. Trustworthy, competitive and efficient, anyone dealing with this company can do so with peace of mind.

Very professional service, we had 10 sash windows replaced, job was done to a very high standard with minimal disruption.

Mark and his team were fantastic! Efficient, professional, on-time, and neat while also fitting the windows to a very high standard. Highly recommended

Replaced my single pane sash windows with double glazed ones. Windows look great both indoors and outdoors. Work completed within time. Cleaned and tidied up. Excellent work. Well done and thanks Mark and Vas.

A very professional team from start to finish. The fitters were efficient, respectable and caused minimal disruption. The quality of finish of the windows was excellent and has significantly improved the appearance of our home. Highly recommend.

We needed our Edwardian Sash windows replaced and went hunting for several quotes and recommendations. North London Box Sash came clear above the others. We have had these for many years now are very please with the decision we made. They look and work as good as new.

North London Box Sash was thorough, professional and assured us of the work and the plans to complete the job, safely, cleanly and with minimal disruption.

What’s more, the replacement double glazed sash look great and do a fab job.

If you’re looking for replacement quality windows and exceptional service, these are the people to go with.

Really efficient company with a good quality and competitively priced product. Wooden sash windows look lovely!

first rate company - excellent work and job well done. no hesitation in recommendation. (replacement to Victorian bay window).

Mark and his team have replaced sash windows on my family homes in North London and more recently Brighton. On both occasions they have delivered a very good service at a reasonable price. Where other contractors advised removing the original 100 year old box frames, at substantial extra cost, Mark was happy to refurbish perfectly good frames and thereby save me cost, and eliminate waste. As an architect I am happy to recommend their services to both residential and commercial clients.

Good, friendly local business. Mark is responsive, reasonable and very good at windows!

A very efficient company, friendly, courteous and punctual. Out of the quotes I had north London box sash was not the cheapest, but they were by far the most professional, I felt assured their windows we were going to be of a much better quality compared to other companies. The finished job surpassed my expectations, I would highly recommend this company.

Would very much recommend this company, very tidy workers, cleaned up every evening spotlessly and were very polite and courteous. The new windows are of high quality and were also competitive on price, very happy on my experience

Mark and his team were excellent to deal with and the finished product is excellent.

No problems - not cheap but quality job. Excellent

Mark and the guys were on point from start to finish and the results exceeded our expectations. Full house Edwardian restoration; some double glazed sashes that were fitted into existing boxes (giving the same original 'slimline profile' finish we were looking for) plus a whole bay of brand new boxes too which look amazing. Would happily recommend to anyone!

Mark & his crew are a top team. Great job and felt comfortable working with them. would definitely recommend
