Sash Windows London Omdömen 

Great service from the get go. I felt confident that going with SWL was the best option and glad I did - the secondary glazing installed in our flat as significantly reduced noise and thermal leaks.

Fantastic experience from start to finish. They visited and were excellent in talking through options and answering questions. Very well organised and responsive. The work is excellent quality. Great installers.

Choosing a company to install new windows is often difficult as there are a myriad of operators..I hit on the Sash Window Company a couple of years ago and was immediately struck by their professionalism, care and competitive pricing, and I was rewarded in my choice by the outcome. Two years on I am having further work done, and I have encountered the same level of customer care, and importantly to me the same personnel in place to help.

My whole experience replacing two sets of sash windows with Sash Windows London was excellent. The estimate turnaround was fast, communication was good, they finished the work in the two days proposed and when their was a small niggle, they were helpful and responsive with the fix.

Fantastic windows and excellent service.

I am not a reviewer in general but felt like it was only fair to endorse such a positive experience. I have high standards and feel forever let down by disappointing trades people, messy or unreliable even when they have sold us the dream. This experience upheld its promise from start to finish. We are thrilled with the end product and recommend them unreservedly. Thank you again!

They are honouring the 10 year warranty to deal with minor defects noted. Happy to recommend them and share the new photos of repairs.

Danny and Darry were great! The entire process was so smooth, no delays, no changes, no unexpected fees. Great job

The company delivered a fantastic service. I was initially sceptical about choosing UPVC sash windows rather than wood sash. However the quality is amazing and it is hard to tell the difference. The sales process was really easy and unlike other companies I spoke to I didn’t feel like I was under any pressure. It is clear the company was confident with their product which sells itself. After agreeing to move forward the process was extremely smooth. Installation went ahead as scheduled. I had other trades on site and they were impressed with the professionalism and attention to detail of the operatives. I was extremely happy with the whole service. I have already recommended the company to a neighbour who is also moving forward with replacing his windows. The company is not the cheapest but this is a clear example of you pay for what you get both in terms of service and quality of the product.

We had two windows replaced recently with double-glazing and Sash Windows did a great job. They were always punctual and professional with communication and the quality of the windows is fantastic. Would definitely use them again.

Almost 8 months ago I had new windows fitted in my flat by Sash Windows London, and I couldn't be more pleased with the results so much so I had them return to fit a new door this month. From start to finish, the service has been exceptional.
The team is highly professional, arriving on time and working efficiently throughout the entire process. They took great care to ensure everything was installed perfectly and left the place spotless afterward.
The quality of the windows and door is excellent, and I have noticed a significant improvement in both insulation and noise reduction.
Communication with James Couch was seamless, he provided clear explanations and options, making the entire experience stress-free.
Overall, I would highly recommend Sash windows London to anyone looking for high-quality window and door installation. Their workmanship, professionalism, and attention to detail were outstanding.

The whole experience with Sash Windows London was excellent from start to finish. I visited the showroom in Battersea and the sales representative talked through the different options. I was keep informed of the installation date and provided very useful information of what to expect on the day.
The installation team arrived on time, they were very professional and friendly. They ensured they cleaned up after the work was completed and ensured I was happy with the job before departing. A pleasure to have worked with a professional outfit.

The installers were great—very client-focused, tidy, and courteous with good workmanship. Very pleased with the quality of windows. However, I was a bit disappointed with the sales team as they didn't allow for (Scaffolding ) access to remove and install the windows, and I had to make a separate payment for this, albeit at a discounted rate. At the time of placing the order, I was told that I would be getting moulding to replicate my neighbour's, which didn't happen. When I flagged this up, no one came back to me with a solution until it was too late and the job was finished.

I can’t fault the company. At every point in the process they were approachable, helpful and thorough. I’m very pleased with my 2 new windows, and Mirel and Marius who carried out the installation were courteous, efficient and tidied up very thoroughly before they left. I wouldn’t hesitate to recommend Sash Windows Company.

This review is a bit late, our new windows were installed 11 months ago. I couldn't be happier with our new windows. We received excellent service from Sash windows and James. The process was quite complicated with scaffolding and pavement licenses but they were so helpful and flexible that they managed to pull through this project.
After almost a year, the windows work great and are really beautiful.

Sash Windows London did an excellent job replacing old wooden single glazed sash windows with uPVC ones! They replaced all windows on our Tooting terraced house.

The quality of the workmanship and professionalism from Gary and Kyle who did the fittings was exceptional! Excellent during the job and the quality of finish is excellent.

The quote (Andrew) and the survey (I unfortunately can’t find my surveyors name) were both excellent. Both spent time answering all my questions and very genuine to work with. Never any pressure to be forced into an option and provided info on all the different types of materials available.

Would highly recommend Sash Windows London.

We had two double-glazed bay windows installed by Sash Windows London Ltd last week. From start to finish the communications were fantastic and the products themselves are lovely (wood grain-style uPVC at the back, timber at the front). Our windows are unusually tall and we had old shutters to work around, which must have proved a challenge. The price was also a much better deal than the others I compared with.

I'm so impressed by the professionalism and pride in their work displayed by everybody we spoke to:

- Andrew, for the initial callout and measurements
- Tony, who did our survey
- Mat and Kacper, who did the fitting
- Andy, who followed up regarding some missing accessories less than a week later
- Mirel, who arrived 20 minutes after Andy to fit the missing accessories
- And the communications staff who were always prompt to respond to queries and send over documentation.

Even the slight product hiccup on the casement window just proved how great the customer service is. We'll definitely reach out to you again for future projects.

Amazing company well looked after from start to finish. Fitters and office staff and management all very friendly and efficient.

Unlike some window and doors, companies, this company gives you a price without demanding an immediate answer and pressurising you with a discount.
They spend time making sure you are happy before the contract is finalised.
The workmen are thorough and competent. The work done was very good, and we are very pleased with the result.
There was one issue arising from the work, but it was dealt with immediately, and without fuss.
I would say that they are worth considering.

Thank you to Sash Windows London! They were absolutely wonderful from the first conversation to installation and all the way through. Thanks in particular to Ben, Tomasz and Philip and the team who were always very knowledgeable when we called with any questions. Everyone made the process so smooth and the work done is exemplary - very pleased with our new windows. Can't recommend them highly enough.
