“Good afternoon James,

The customer on the attached order was broken into.

They did not manage to get access in via your door- so that good news. but they did try.

Please can you reprice this job as it was all damaged – See pictures attached

Kind Regards

Zoe Brown”

Hi Richard, Biljana,

Thanks so much for all your kind assistance so far with the windows for Triangle Oast – it is very much appreciated. 

Equally I am impressed by the quality of the windows that you have provided!

The window installation finally started last week and is proceeding well.

Despite all our diligence during the planning process, there are 2 windows that need to be remade please. The details are below. Please can you provide a quote to remake these 2 windows…

Hi Stephen,

I’ve just sent your company the below and look forward to hearing from you! It’s a really exciting project and I hope we can work together as I’ve heard great things about your company.

Alan, Twickenham TW2  (Trade Customer)

“Thank you for the door and window we are really pleased and a very nice driver delivered them for us. I must say we are really pleased to work with you it is a real pleasure.

Good news I think Mr Horsfall has given go ahead for the five windows and is not having door or roof from us so that is fine. I did not want to agree and order something that he may have rejected. So let me know what we owe you and we will send the money over. We would like the windows asap.

We will be fitting our showroom door next week so very exciting.

Megan comes back to work Monday so the piles of paperwork on her desk will be addressed and sorted and she will be able to go to the bank which I have had not had time to do.

I am sure we will be selling many front doors for you.”

“Just a quick note to say how over the moon we are with quality and finish of our windows. My husband has never seen such fabulous wooden windows and we are over the moon with service and quality. We will also recommend to all our customers who do not have PVC.

Thanks and regards”

Alan, Ultralux Windows Ltd, TW2  (Trade Customer)

“ATW are positive, friendly, professional, honest, providing reliable service and high quality. We feel it is like doing business with our friends. Ultralux Windows and ATW have a strong working relationship and we are delighted to have found a business partner who put themselves out for us.

I would have no hesitation in recommending ATW and to have found a joinery works who manufacture quality products has added to our business possibilities and we can with confidence quote for the installation of high quality timber windows and doors knowing that our supplier will deliver on time.

We are finishing today a ATW timber conservatory with solid swept heads and finished in white and it is stunning.

Ultralux has been installing windows, doors and conservatories since 1969 and we think that ATW is a quality business partner.”

Neil C, SL3

“Definitely consider speaking with ATW if you are looking for wooden doors/windows.

We had 2 x bi-fold doors, french doors and a kitchen window made.

I must say you can feel the quality when you open them, and the finish exceeded expectations. we went for the wood stained to an oak finish and they do look like oak, (spare stain included should you need it, we didnt).

Its transformed the look of our house and its fantastic having both sets of doors open in the summer months.”

Terrance M, SE19  (Trade Customer)

“Having used other manufacturers in our 20 years experience Authentic Timber Windows have not only got the best prices, but also deliver the best quality of windows and doors. As installers we can highly recommend ATW, and we are looking forward to many more years of effective collaboration to come.”

Premier Windows, SE19  (Trade Customer)

“We’ve been dealing with ATW for almost 10 years now. Brilliant customer service, quick turn around and reasonable prices. Most importantly the products are of the highest quality! Would definitely recommend to anyone looking for timber windows and doors.”

Mr. Sidney, SE15

“A big Thank you!

We are very pleased with our new front door and now feel much safer. It is of great quality & very solid. We live in a conservation area so we will also need some timber windows soon as well.”

Alan  (Trade Customer)


Thank you for the door and window, we are really pleased and a very nice driver delivered them for us. I must say we are really pleased to work with you it is a real pleasure.


Nick Gautama, SW2

“Your company has proved to be a real winner.

I had windows done in the past with another company and, I was very disappointed. Once bitten twice shy!

Of course I was wary at first with using another company but you really have provided the quality I needed.

Excellent service and accurate delivery time too!

Regular communication and updates on my order and keeping me in the loop was extremely important and you certainly delivered there too. I would not hesitate to recommend you, and I will definitely be using you again on my next project.”

Andy, CR8


Thanks for e-mail.

Yes, I received the door knocker but haven’t tried it on the door yet.

Fingers crossed it will be OK.

Many thanks for your promptness in sorting out the problems.

Hope you have a Merry Christmas, and Happy New Year.


Neil Commerford, TW15

“Thanks Steve,

Yeah, getting there, plasterers start next week, so windows and doors to go in this week.

The first set of bi-folds look great, very pleased with them!”

Jen R, E7

“We got two beautiful timber doors, double glazed sash windows, a fixed timber window and bay windows from Authentic Timber Windows are we absolutely love them. They are flawless, and just make such a huge difference to the appearance of the house. There’s not a single nick or brushstroke that we’ve spotted. They make a HUGE difference to the temperature of the rooms versus the double aluminum windows they replaced, too. The manager even helped us design a window above the door, with the print of the house number, and a little sunrise design in timber which makes the house look really elegant (we think!).

The staff were quick to reply and update us of everything we needed to know. They helped us choose what we needed up front, too, in terms of styles and handles etc. – be warned there’s lots to choose from!”

Sara Lang, SE15

“Very pleased with our new Sash Windows.”

Hannah Marden-Jones, SE17

“I am very happy with the bifolding doors and Sash windows we just got from Authentic. The finish is beautiful- very pleased.”

Cole Sitton, EN9  (Trade Customer)

 “Hi Steve,

Good to see you the other day.

Pacheco’s doors look stunning and client is very happy.”

Natalie Pantic, SW16

“We could not be happier with our new Bi-Fold doors, not only was delivery on time but we have finally found a company that likes to keep you updated on the progress and the quality is excellent. We have a few more windows that will need replacing so will definitely be in touch again in the near future. 

Thank you.”

Philip Owler  (Trade Customer) 

“Dear Mia,

I’m happy to pay the additional cost and so very grateful that you raised the question of the gaskets. It would have been a disaster if it wasn’t noticed until after we had installed them.

Thank you so much for your help with this, I’ve used many different timber window manufacturers before I found ATW and you are without doubt the best, you’re always helpful and professional and nothing is ever a problem that can’t be resolved.

Kind Regards

Philip Owler”

Dean Wilcox, DU12  (Trade Customer) 

“We have used ATW numerous times as our main supplier for timber products. Their quality is exceptional. Service and communication are excellent, Mia is a pleasure to work with, a very professional company throughout.”

Trevor Pickering, SW16  (Trade Customer)

“Hi Helen,

I have now received and installed my doors.

I am VERY impressed with the quality of the product and the paint finish is outstanding.

I would not hesitate to use your company in the future
