I was very nervous about purchasing replacement double glazed patio doors and contacted four different companies. I decided to go with SDG windows because they gave me an honest quote and I was able to actually see the doors that I would receive displayed in their office. They made the whole process stress-free with their helpful and polite service, especially the main office person Vic. They were fast, efficient and clean and fitted quality patio doors that look great! I would definitely use them again.Mrs French

“Our landlord had our rental property's windows upgraded recently from single pane windows to double glazing, by SDG Windows. The difference to noise pollution, heat loss, and energy saving is immense. The team arrived bang on-time and worked hard, non-stop for four hours to change the four windows in our flat. Their attention to detail was faultless and they tidied up as they went. The senior member of the team was friendly and chatted us through the working of the windows and locks etc. We are very happy with the results.”

“Fantastic people. I was looking to find a company that could replace some windows in my elderly aunts flat. I contacted Vic at SDG windows and from the very first email the communication was first class. They arrived on time to do the installation and the quality of their work was excellent and they were so clean and tidy. A big thank you to the team at SDG.”

“Having read the reviews, I first used SDG for one window whilst renovating the kitchen of my Victorian terrace. I wanted high end UPVC sashes, as close to looking like wood as I could get. Vic was great from the start and chatted through all the options. I was so pleased with the result that I ended up using SDG to replace the rest of the windows in the house. The result was exactly what I wanted, with the finish on them so good that the decorator was certain they were wood. I've gone on to recommend SDG to several neighbours in my street, all of whom are equally delighted. Vic, Shaki and their team are highly skilled and a pleasure to deal with, the product was perfect and the price was very reasonable. I would wholeheartedly recommend SDG in a heartbeat - they're a real asset to the area.”

“We recently had 5 UPVC windows installed by SDG Windows, and we couldn't be happier with the results! From start to finish, Vic's communication was excellent - clear, friendly, and always quick to respond. He worked with our budget and delivered exactly what we wanted. On installation day, the team arrived right on time, worked efficiently, left everything clean and tidy and were quick! The new windows are great quality and have really improved the look and feel of our home. Great service all round, I highly recommend SDG Windows! Thanks Vic!”

“We had a great experience getting all new windows for the whole house and new front and back doors. The workmen that installed them did a great job and left very little mess / tidied up the corking / sealant on the old window ledges really well. Service was great working with Vic from beginning to end. Had the FENSA certificate with grantee delivered shortly after installation also. Added the windows being French door style to half the windows and are a really happy with how they work! Price was very reasonable and didn't include the questionable / dishonest charges that another very well known national company gave us. Would really recommend contacting them as was no pressure at all and was easy to organise from beginning to end!”
