SRJ Windows is proud to offer such a large range of double glazing products to Perth homeowners. In doing so, we can fit every style of property in Perthshire, be it heritage, traditional, modern or contemporary. We manufacture our double glazing products at our Rosyth factory, allowing us to guarantee that only the best products will be installed in our customer’s homes. If you choose SRJ for your home improvement project, you can expect a quality product matched by a quality service.

Modern Materials For a Quality Product

By making products ourselves, we can carry out a high-level of quality control and only offer the best products. Each double glazing product is fitted with the latest secure hardware, with multi-point locks and secure technology offered to Perth homeowners as standard. With each product comes a 10-year guarantee of quality, giving Perthshire homeowners the confidence to entrust their home improvement project with SRJ.

Here are the double glazing products that we install in homes across Perth and Perthshire:

Double Glazed Windows

We pride ourselves on offering a vast range of windows that offer something for every Perth home. We manufacture our double glazed windows using the finest uPVC and aluminium profiles to create a low-maintenance product that performs above expectations across the board. Thermal efficiency, security and weatherproofing are just some of the benefits you can enjoy for your home in Perth. You can get these double glazed windows installed in your home:

Double Glazed Doors

A new door should offer more than good looks to Perth homeowners, which is why at SRJ, we offer doors that not only complement your windows but offer a variety of benefits. Like our windows, we offer a variety of different styles from uPVC, aluminium and composite profiles, giving you a door for every type of home. Whether you want a double glazed door that keeps the harsh Scottish weather out of your house, a door so you can enjoy your garden year-round, or a door simply to secure your property in Perth, we have a style for you.

Our low-maintenance doors come with a 10-year quality guarantee. Benefits of our double glazed doors include improved thermal efficiency, security and weatherproofing. Our doors trap heat into your home, reducing your reliance on your central heating, which will reduce your energy bills and your Perthshire home’s carbon footprint.

You can choose these door styles for your Scottish home:

Home Extensions & Replacement Roofs

If you are looking to add some more space to your Perth home, then why not consider one of our home extensions. Our custom-built extensions, including double glazed windows and doors meet the needs of Perthshire homeowners, with a perfect fit for all property styles. One extension we offer is the traditional conservatory, of which we offer three different designs: Classic, Designer and Performance. If you’d like an extension that blends into the existing architecture of your home, then one of our orangeries & sunrooms could be the right option for you. In our orangery range, we offer: Traditional, Lantern and Contemporary.

For those who need to update an existing conservatory or are looking to add the perfect finishing touch to a new extension, we offer a variety of replacement roofs, including the tiled conservatory roof. We’ve worked hard over the past 30 years throughout Perth to provide the best extension that meets the needs of our customers. We use NASA satellite data when designing our house extensions to ensure that they can cope with the changeable Perthshire weather. If you choose SRJ for your next home improvement project, you’ll receive excellent service and a product to match for your Perth home.

Customer Testimonials

Mr Albert Peoples

From the initial contact there was no pressure. We never felt pressurised and had plenty of time to consider if we wanted to proceed. When we decided that we were going to accept the quote, we were given a complete breakdown of the various ways we could consider for payment. When the team arrived to complete the job they arrived on time, were polite and tidy workmen. The whole job was completed on time and there was no mess left behind for us to clear away. We were aware that there are cheaper companies around, however SRJ have a good reputation and a first class 10 year warranty on their kit. Both my wife and I are well pleased with the new windows and the follow up service given.

I had SRJ windows put into my home 22 years ago, Woodmill crescent Dunfermline. They took out two windows and replaced them with a big bay window, then did all the house and doors. Not one piece of rubbish did I pick up or clean up, they were amazing. So a few months ago, we needed a new door in our new house. Straight back to SRJ, never even thought of going anywhere else. Again they left the house and garden spotless. Workmen were brilliant not just with us but the were good with our neighbours also. My new door... absolutely beautiful, strong and sturdy. And no draughts. I will have no hesitation in using SRJ again and again. I am always recommending them too. Brilliant. Thank you.

This is our second time using SRJ for our windows as we moved home. We were in no doubt as to who we would use for our new home. The service was excellent and everything was installed efficiently and looks brilliant. We are about to use them again to fit new French doors wouldn’t consider anyone else now the quality and service is unbeatable

The staff have been great, from the salesman to the fitters to the after sales care it really does feel value for money. The windows and doors look great and have made a huge difference in our house. We needed a little bit of plastering afterwards which was followed up quickly and when was convenient for us.
