North London Box Sash Opiniones 

A very professional job from start to finish.
Mark came round on different occasions to measure up and provide quotes.
The windows were made sooner than I was told and the team who fitted them were very professional, even finishing the job sooner than I was quoted. They were very polite and industrious and cleaned up well after themselves at each stage.
I would have no hesitation in recommending North London Box Sash and I now have a much warmer house with hopefully lower heating bills!

Expert advice during the planning phase. Clear quote with clearly written T&Cs. Very good communication throughout. Fitters were careful to protect the interior of my house during fitting of new windows. Punctual and polite fitters. Excellent windows installed with a smooth action. Room temperature is so much warmer and room is quieter.
I couldn't fault the service.

One of my windows was damaged, probably by a rogue pebble. The guys who replaced it were fast and courteous. It took some time for the manufactured window to arrive, but overall I think that North London Box Sash are excellent.

Great service. Mark and his team were professional, efficient and friendly. I love my new windows.

North London Box Sash replaced all our casement windows and French doors. The service from start to finish was outstanding. Mark was really responsive and took the time to understand exactly what we wanted, making sure no detail was overlooked ahead of placing the order. Once the order was placed we received frequent updates regarding the timing of delivery. The team of installers were very professional and tidy and clearly took pride in their work. A highly recommended company who I would definitely use again.

We had 3 uPVC back windows and our uPVC back door replaced with wooden casement. The doors/windows themselves are very high quality with a 'solid' feel and the workmanship was top notch. They are very personable and professional (both in the office as well as on site). They worked with us on price and were quick to help when we wanted something adjusted. We will definitely use again in the future and we always recommend to friends/neighbours.

Communications very prompt, responsive to queries and gave advice when needed. Installation quick, tidy and did a very professional job. Double glazed sash windows to bay at front of the house, Less road noise, warmer and look great.

Really happy with the windows, had two sash windows installed and everything was completed on time and to budget, and they look fantastic! Highly recommend and will use again

I recently had North London Box Sash replace my windows, and I am thrilled with the results!

I highly recommend them for a hassle-free and impressive window upgrade!

I had two old metal windows replaced with wooden sashes by North London Box Sash. Although more expensive than some other window companies, it was worth it for the quality of the windows and finish provided for the additional masonry work needed for the change in window type. The installers were excellent and finished the remedial work and painting to a very good standard. I will definitely use them again.

Brilliant service all round
The team at North London Box Sash were communicative, fairly priced, and very understanding of needing to work round other contractors on site as we had other building work done in parallel. The finished window is just gorgeous, we would definitely use them again!

The front sash windows of my Georgian cottage (in a Conservation area), were all in need of replacement. I came across North London Box Sash company by lucky chance.

Their free quote for total replacement with double glazed wood like-for-like sashes was carried out meticulously, and supplied with full illustrated technical explanation, (included installation and removal of the old windows). I had had rough quotes before, but felt that their service and product offered was very competitive.

It’s rare to be able to say right from initial enquiry, quote, acceptance contract, through to installation, I was really impressed with the quality and top skill professionalism of all who were involved. It was a genuine pleasure to have used North London Box Sash company and I remain grateful for the superb appearance of the windows, inside and out, as well as the noticeable difference in insulation with double glazing!
