“I would like to take this opportunity to thank your team for the excellent job that they completed yesterday.

They arrived each morning at the time they were due, they worked hard until they left each evening.

They worked very well as a team, whoever the team members were each day.  Best of all they vacuumed the area in which they had been working each day to within an inch of its life, however, they didn’t eat all the biscuits that I had bought for them and so now I have to eat the remainder!!

They did a fantastic job and it was a pleasure to have them in my home.”

Mrs Jean H Soden

“Mark and his team where very easy to work with, no fuss and works where carried out in a professional manner. They sorted out an old bay window in our lounge with new bottom sills and draught proving strips. We really notice an improvement when sitting in the lounge, watching telly, much more comfortable now. I recommend Sash Window Experts.”

Bram van Huet Lindeman

“Mark and his team take great care around your home. They are friendly, considerate and do a fantastic job. Highly Recommended.”

Will Mulvey

“Mark, Gary and Dave have done a fantastic job repairing our Georgian sash windows this last week. Considering ours were broken and painted shut and 200 years old, they now look and work like new. Worth every penny and you couldn’t meet a better group of guys to work on your house. Everything was left spotless. Thanks Mark and team and hope to see you again soon for secondary glazing once I’ve sorted out permission.”

David Mortimer

“Mark and Gary were a great pair to deal with. Refurbished our window neatly and professionally and will deal with again. Strongly recommend their work and have no hesitation. In fact neighbour is so impressed they’re going to make contact.”

Charles Fachiri

“These guys are awesome! Quality work and the added bonus of being nice chaps. Are windows are superb. They are clean workers, efficient and honest guys. Would happily recommend and use again!”

David Frosdick

“Mark and his team did a great job restoring our sash windows. They were all really friendly and were clearly passionate about their work. They left the house really tidy (It’s never going to be spotless with that amount of dust flying around the house). I would recommend Mark and his team to anyone looking to complete work on their windows.”

Matthew Walkowiak

“Having been through a variety of quotes from painter decorators, joiners and window repair specialists over the 4 years since we moved in to our house we were unsure which direction to take regarding major refurbishment/touch up/replacement, and not convinced we had found the right company for the job.

On a whim I had a fresh look early this year and came across Mark’s firm. Speaking with Mark he was clearly knowledgeable and gave me the confidence that he had tackled worse repairs than ours (2 double height bays, 12 sash windows in total) and was experienced in his field. We finally took the plunge and booked him in, and are very glad we did so.
I would echo the views of many of the other reviews. Mark and his team are courteous, professional and great workmen. He carried out major overhauls on nearly all of the windows and I was pleased to see the quality of the woodwork and thoroughness of the repairs.

Also of note is my wife felt comfortable with the team around being around the house when she was at home with our young daughter.

I would approach Mark as a first port of call for any further window restoration work we need down the line.”

Ashley Meares

“Excellent work, carried out window refurbishment and supply/fit secondary double glazing. I would recommend them.”

David Bicknell

“Sensible, accurate quote. Friendly, polite efficient service. Windows look great and no more drafts. Overall great job!”


“I cannot recommend this company high enough! Their professionalism and workmanship is truly 1st class. Thank you Mark, Gary and the rest of the team. My sash windows and the repairs you did to our French doors make them now perfect.”

Jennifer Tomkins

“Hard working and professional team, would recommend.”

Eliza Czajko

“Excellent work, and very good service throughout.”

Pete Burden

“Great job, professional and friendly to deal with and have done a great job on the windows.”

Claire Cox

“We were impressed, both with the prompt response and quote and the completion of the work itself, by a team of hard-working, pleasant professionals who respected the fact that they were in someone else’s home. They completed their work very efficiently and promptly and to a very high standard. We would gladly recommend them to others.”


“I’m really pleased with the work and service. They turned up on time, were polite, and friendly, did a great job, cleared up their mess and left. The window itself now glides up and down smoothly and hopefully, the new brushes will keep out the draughts in the winter.”

Clare Slater

“Very happy with the service and the secondary glazing windows. They couldn’t have been more helpful.”

Charlotte Gann

“Myself and my partner loved the old sash windows we had in our house but they were a pain to open and close and rattled like crazy, we found Mark online and got him round for a quote to repair them. Price seemed fair and he was very knowledgeable, now the works been done it’s literally like having new windows, they don’t rattle, no draft comes in and they open and close smoothing and quietly. Absolutely delighted with the service and would highly recommend Mark to anyone, we’ve already done so to many of our friends.”

Alana Burton - Haywards Heath, West Sussex

“Last Friday for the first time since we moved we able to use our sash windows in the living room.
It was a wonderful hot sunny day and so nice have the windows open, it was truly wonderful and all due to your hard work and the work of your team. We love our hobbit house all the more now. So a big thank you.”

Stuart and Fiona Reynolds - Tonbridge, Kent

“Dear Mark – Many thanks for renovating the main sash windows front and rear.

The work is excellent. I have cc’d this e-mail to my neighbours.”

Robert Bailey - Richmond, London

“Love my refurbished windows by Mark. Thanks for all the hard work, the house already feels warmer with the double glazing.”

Holly Bryant - Hurstpierpoint, Sussex

“Supremely happy with the work carried out by Mark & Charles to my 200 year old windows. Even when more rot was found than expected did not phase them. Total back to the brick rebuild of one sill and tricky casement with parliament hinges and un-true frame. Quality and courteous service. New ‘fluffy’ seals already greatly reduced road noise from busy street outside…! Would highly recommend. Happy to give referrals. Cheers Lee.”

Lee Cooper-Keeble - Guildford, Surrey

“Hi Mark, We had Gary and his assistant here this morning to repair one of our sash windows. I just wanted to say what thoroughly professional, knowledgeable and personable people you have working for you. Gary would now be my first port of call for any window issues that need work and I wouldn’t bother looking elsewhere. Please pass on my thanks to them.”

Peter Tappin, Land and New Homes Manager Romans Guildford

“I cannot recommend Mark and his team highly enough. Having been quoted a fortune by huge window replacement companies (we were probably paying for their TV advertising!)we thought we’d try several smaller businesses. Mark spent time with us and impressed us with his knowledge. He was head and shoulders above the competition and price was very fair. He and his team restored and/or replaced all of our front windows and front door, and then we asked him back to do French windows.

The work was outstanding. Ours were very old original windows so the work was authentic and each window beautifully made. Mark and Charlie were friendly, totally trust worthy (happily left them with the house keys) and tidy workers. We were thrilled with both the work on our house and their whole approach to customer service. Brilliant. If I could leave 10 stars I would.”

What Our Customers Say

Helen Thomas
If I could clone you for all the other work we need to do over the next few years, I would! Thank you Mark for having such a good team in place. And huge thank you to Gary, Alex, John and Glen for taking such care of our windows and giving them what they needed after years (decades?) of neglect. Your attention to detail and 'doing it right' was very much appreciated, and your ability to solve problems was awesome. Helen & Tim, Godalming
Roxana Avanu
Amazing service from start to finish, no issues and no drama. The name Sash Window Experts is well chosen. Mark and his team - Gary and John were extremely helpful and professional and the end product - new sash sound proof double glaze windows upstairs and the kitchen triple sash window restored was top quality. I am very grateful to Sash Window Experts.
Amy Clarke
Cannot fault Mark and his team. We replaced the original sashes to our 1890's home with new like-for-like hardwood double glazed sash windows, and apart from being warmer, quieter, cleaner and altogether much smarter, you really wouldn't tell the difference - an amazing feat! They are absolutely beautiful windows, so well crafted and fitted, and the restoration of rot on the original box is imperceptible. Gary was friendly, clean, professional, and safe throughout the fitting, and very thoughtful in causing minimal disruption to the home. Absolutely thrilled with everything from the service to the price to the final finish. Delighted with them. Would recommend in a heartbeat.
Alison Fordham
We were nervous about getting our Victorian French windows restored and had received a ridiculously high quote. Sash Window Experts came in at a good price, gave a timeframe that worked with our schedule and did a great job. All as promised. The fitter, Gary, put the doors back in with great care and took time made sure they worked smoothly and also discussed any queries with us. Definitely made the job value for money. Very happy customers! We are looking forward to beign able to open our doors again and enjoy the garden. Thank you Mark and Co!
Peter Jones
Our house is Edwardian and has the original sash windows from 1906. I really want to make sure that any double glazed windows did not look out of place - so the woodwork, including the side bars etc should still be very thin to match the originals. I was fearing ending up with fat wooden bars but Mark took me to see a previous customer and I was happy to see the woodwork there and it put my mind at rest. We went for the thin Krypton windows. Now the windows are in they look very good and match very well. To be fair to everybody, we will not know until the winter how well they remedy our warmth and condensation issues in the house but are confident we made the right choice. Other suppliers would not do separate window panes and instead would only do a large window with a false wooden strip down the middle to make them look like two. We did not want that. The carpenters, Steve and Gary turned up on time (early actually) and got on with the job very efficiently and left no mess behind. I am very happy with the company and the windows.
Natasha Birley
Mark and his team are amazing. They restored our sash windows and doors. Mark is really knowledgeable and passionate and explained the process to me so I knew exactly what they would be doing. Once the work commenced I was amazed by how well they draft proofed the windows. They took so much care and the guys were polite, tidy, timely and a joy to have around. I would absolutely recommend the team to anyone thinking of restoring their windows, they look AMAZING!
Rachael Smith
Absolutely outstanding quality, value for money and service from Rob. This is the second time Rob has done work for us and we can highly recommend him. The sash windows are like new! Thanks Rob 😀
Jon Reed
Used these guys to do a total refurbishment on the windows of my 1870s Victorian Villa style house. Incredibly happy with the work and the guys doing it are just superb. On time to the minute every day, clearly take pride in the work they do and super friendly. Would not hesitate to use again!
Geoff Parsons
