House Extensions & Replacement Roofs

At SRJ Windows, we don’t just offer windows and doors to our Alloa customers. We also install a variety of home extensions that are custom-built to fit the architecture of your Falkirk home. One extension we offer our customers is the traditional conservatory, of which we offer three different designs: Classic, Designer and Performance.

If you want a home extension that offers more privacy than a conservatory and blends with the existing architecture, we also install a variety of orangeries & sunrooms. In our orangery range, we offer: Contemporary, Traditional and Lantern.

The Clackmannanshire homeowner can also opt to add the perfect final touch to an extension or improve an existing conservatory with a new replacement roof. We’ve worked hard over the past 30 years to provide the best product that meets the needs of our customers. Our extensions are manufactured using NASA satellite data, so you’ll be receiving excellent standards and an excellent product for your Alloa home.
