Thermally Efficient

Upgrading your double glazing should mean that your home will work more efficiently. Unlike older windows and doors, our double glazing boasts excellent thermal retention capabilities. When professionally fitted, the vacuum-sealed nature of double-glazing traps heat behind thermal barriers, which will result in your home being naturally warmer. At SRJ we utilise anti-draught mechanisms during the manufacturing process to further back-up our profiles heat-trapping capabilities.

Being able to enjoy a more comfortable home, free of draughts and cold spots will mean Downfield homeowners will rely less on their central heating. This is will result in lower energy bills and a reduced carbon footprint. Save yourself money and be kinder to the planet with double glazing from SRJ.

Customer Testimonials

Scott R

The experience from start to finish was excellent and would highly recommend. We started off by going into the showroom to look around and the team there explained all options to myself and my wife. We then arranged to have a home survey later that day. Everything was explained to us and the different costs. No pressure to buy and when we said we would like to think about it the salesman was more than happy to leave it with us. Called him a day later to place order and get our date. On date of installation the team turned up early and removed the old door quickly and cleanly before installing the new door, again within a good time to make disruption for the school run non existent. Everything was cleaned away and explained to us on the up keep. I'd definitely have the team back for future windows and doors within the house.

From start to finish we can’t fault the service. From Darren’s initial visit talking us through options for our windows and measuring up to the joiners fitting them we couldn’t have asked for a better service. No forceful sale just a genuine company who done exactly what we wanted including cutting the trim down so our blinds would still fit.
Ruth

Lovely company, all the people are so helpful and they completed the job exactly when they said they would. The fitters cleaned up when they finished and we got a follow up call after a few weeks to check we were happy with their product and service. Highly recommend them
Kirsteen
