Excellent service, workmanship and professionalism – I am very happy and impressed with my new windows. Each day, the team turned up on time, did the work without any qualms, and cleaned up afterwards. Melissa and Dan were very efficient and professional in getting back promptly with any queries. Would totally recommend Sashwise without any hesitation!
The whole experience from initial telephone enquiry with the office to the final conversation on site was excellent. I was fully informed what was happening when at all stages of the work and we are very happy with the final product. Melissa and Dan were the main contacts and were brilliant both very professional and friendly. We would recommend Sashwise and use them again.
I was very pleased with the work carried out. Dan was polite and tidy& worked hard. The windows now look great, no drafts and open and close easily.
All interactions with the Sashwise team have been excellent from start to finish, highly efficient and clear communication throughout. The quality of work is excellent, the rather shabby box and sash windows now look like new. During the work on site, the team made every effort to minimize dust and disruption. Co-ordination of estimate, program and invoicing by Melissa, super efficient and very friendly.
A great experience, and an exceptional team effort. From Mellissa in the office, friendly helpful, knowledgeable, and keeping us informed through the whole process. Dan the owner involved and passionate about his product and service. The craftsman/fitters who delivered the service and fulfilled all the promises made during the process. It is refreshing in this day and age to find such a company who have been a joy to be customers of.
Thank you very much and I am very delighted with the works you have done. Your team, was very helpful from the beginning until the end of the works. The fitters, Dan and Tim were very skilled, professional, hard working and very polite. The quality of the workmanship was excellent! Excellent service, product and installation. Very pleased with the final result. Strongly recommended.
I had 4 sash windows refurbished and the work was very well done. I’m delighted to have my windows working again.
I was incredibly impressed by the quality of work and professionalism demonstrated throughout the process. Some of our windows needed significant repair and everything was handled expertly without signs of breaking a sweat. I would trust them implicitly to do a flawless job again in the future.
Dan, Tim, and the team where complete professionals and did a really fantastic job. I am incredibly impressed with their work and skill.
The windows are amazing! The men left everything clean and the workmanship is incredible. Our house is very old so I was concerned there might be issues with the fitting but no, they’re perfect! Would highly recommend Sashwise to everyone.
I can not recommend this firm highly enough! They were one of the first to come out, at the end of lockdown, to quote. They explained what would need doing to my windows, and agreed a date within a month and completed the work. My Victorian sash windows let in draughts and did not stay open once lifted, without a wedge. Tim who carried out the work was punctual and incredibly tidy, and has done an amazing job, leaving my room quieter and warmer.
We were so pleased with our sash window, it looks great and works beautifully. Barry worked hard and cleared up really well at the end of each day. We would thoroughly recommend the company.
Tim was highly professional and thorough and the finished windows exceeded our expectations. A thoroughly nice man, too!
I’m delighted with the work, thank you and please pass on my thanks to Dan and Tim.
I am very pleased with the results. Barry was a very good workman, leaving my property in a very tidy state.
We are very happy with our beautiful windows and shutters, and the overall service received from Sashwise, which has been head and shoulders above our experience of other local businesses.
Many thanks for a great service and being such a professional company to deal with.
Many thanks, I’m delighted with the results, please convey my thanks for a super job.
Tim just finished our windows and we are totally thrilled with them. Not just that but Tim was so helpful, professional and skilled that we wanted to pass on our gratitude and would be happy to give a testimonial for any future possible clients.
I just wanted to let you know that we are delighted with the work. Barry was absolutely professional – punctual, polite and hard working. I could not have asked for a better craftsman. I will definitely recommend you.
