House Extensions: Build a Bigger Home

If you’re looking to maximise the amount of available space in your Stirling home, then one of our house extensions is just what you need. Perfectly crafted to expand your property, your extension can be customised however you see fit. That way you can rest easy in knowing that you’re getting a bespoke product that will both wow your visitors and dramatically increase the value of your property.

We’ve been helping homeowners like you complete their home improvements for over 30 years. Our talented installers are qualified and experienced, and our teams here in our offices know everything there is to know about house extensions. With a variety of roofs, hardware modifications and more to choose from, you stand to benefit from a truly modern extension.

Customise Your House Extensions

We want our house extensions to accurately reflect the personal aesthetic tastes of our customers, which is why we offer such a broad range of customisation options. With plentiful window and door styles, you’ll be able to tailor the physical aspects of your extension without issue. You also choose the shape of your project, from P-shapes and Georgians to the Lean-To and Gable designs to name just a few.

Whatever style you pick, you’ll also be able to select from our range of solid, tiled or glass roofing options, each of which offers its own features and benefits. We’ll help you find the right one! You can also choose the placement of your glazing panels as well as the fascia colouring. Choose SRJ as your installer to guarantee yourself one of our bespoke house extensions.

Highly Secure House Extensions

Security is of the utmost importance when it comes to contemporary house extensions, which is why we address all the latest concerns in our product-lines. With impact-resistance double glazing that’s almost impossible to damage and powerful masonry that’s near impervious to any assault, your new purchase has been designed to keep you and your family safe within your home.

There’s no need to worry about an extension compromising the safety of your property; modern manufacturing techniques imbue all our windows and doors with intricate multi-point locking mechanisms and powerful frames which are resistant to both physical damage and the wear and tear of the erratic British weather. Unwanted visitors, rotting, damp and more are problems of the past with modern home improvements.

Thermally Efficient Homes

Staying warm in the winter is vital, and many modern homes are properly equipped to deal with this. Our house extensions are no different! The same double glazing that keeps you safe will also keep you warm by preventing heat from escaping through your windows and doors. The profiles in our products are similarly designed to block off draught-points, preventing cold ingress.

The masonry columns that make up the bulk of our house extension designs are also super-insulated and feature a further-insulated internal pelmet for extra warmth. The result is a brand-new room that doesn’t rely on your central heating; instead it will warm itself by naturally maintaining the existing temperature. The results? You’ll spend less on central heating, increasing your home’s Window Energy Ratings.

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.
