On July 19th, England reached the fourth step of the governments roadmap. Here at SDG our main priority has been to protect our staff and customers throughout this pandemic. We therefore ask if you or anyone in your household have COVID-19 symptoms or a positive test result you should contact us prior to your appointment or installation to re-schedule. Read more

First class work. Easy to deal with. Beautiful door. Highly recommended.
Absolutely delighted with work carried out which included facias, soffits, guttering, 2 bays and 4 windows. The team were professional, punctual, polite, tidy and work has been carried out to an exceptionally high standard. Contact and communication with company has been flawless. I cannot recommend highly enough, one very happy customer here!
“I approached a few companies about getting a new window fitted in the kitchen, speaking with SDG it was clear that the reason the previous owner had not upgraded to double glazing was because the door shared a frame. I was quoted for a new window and door which seemed a reasonable price compared to other companies. The team that came round to install them were great, the install date was even brought forward by a day. A very high standard of work and even the whole area indoors and out was left spotless. Great to work with from initial quote, survey to install.
Our builder used SDG when he completed our extension so it was a no brainer when we wanted 8 new replacement windows for our home. Excellent on the day of installation. Great value for money. Really friendly service. Would always recommend.
Can’t recommend Sidcup Double Glazing enough, there was no hard sell a reasonable price and a great service from start to finish.
I can’t rate this company enough, from the start to the finished job it was smooth and professional. The lads were great workers and a great quality finish with their work. They have been very helpful and made sure I was completely satisfied before payment requested. I would recommend them fully. They work best when supplied many cups of tea 😉
