Giving the Mountcastle Customer a Variety of Styles

Our customers love that they have such a variety of choice when looking at our double glazing range. Our products will not only enhance any Mountcastle or Edinburgh property they are fit in to, but provide other benefits such as adding more security and making your home thermally efficient. Our team carries out fittings to the highest quality, so if you choose SRJ for your home improvement project, you’ll receive nothing but the best service. After leaving our Mountcastle customers more than satisfied with our double glazing installations for more than 30 years, it’s safe to say we know how to meet our customer’s standards.

Making Your Property Secure

Our range of double glazing range will improve your Mountcastle home in so many ways. When purchasing any double glazing product, an important thing to consider is whether it will improve the security of your home. Our range of uPVC, aluminium and composite products are manufactured to be highly secure to keep you and your family safe. Our products can also reduce your home’s carbon footprint and are available in a variety of customisation options to suit you.

Whether you’re looking to add an extra room to enjoy the sun at your Mountcastle property through the installation of a conservatory, or maybe you want to add an extra layer of security to your home through the installation of a new door, we can find a product that will suit you. We offer the following double glazing products to our customers across Mountcastle & Edinburgh:

Double Glazed Windows

Our uPVC window range can be matched to any style of home in Mountcastle, whether it be old or new. All our windows come fitted with double glazing and made with the latest window technology as standard. This will not only make your property more secure, but much more energy efficient and could save you money on your energy bills. The different types of windows we offer our customers are:

Double Glazed Doors

When you buy a new door for your Mountcastle home, you want to be sure that it is manufactured from premium-quality materials and that the installation matches. Our  uPVC door range will provide your house with an extra level of security and help to make your property more thermally efficient, saving you money on your energy bills. At SRJ we offer our customers the following types of door from our double glazing range:

 

Other Double Glazed Products

At SRJ, we don’t just specialise in the installation of windows and doors. We offer our Mountcastle customers a variety of other products. You may choose to improve your home by getting one of our conservatories installed. We offer three different types of conservatory: the classic conservatory, the designer conservatory and the performance conservatory. If you would rather have a space that feels like a conservatory but gives your Mountcastle home the benefits of an extension, we also offer orangeries & sunrooms. Our customers can choose from a contemporary orangery, traditional orangery and a lantern orangery.

Other double glazing installations we can fit in your home include house extensions and replacement roofs. A conservatory is the perfect way to open-up your home and utilise natural heat, letting you benefit from the Mountcastle sunshine. With more than 30 years of experience, our installers will make sure to meet your needs and tastes. Our extensions are built to accommodate the weather in your area, whether that be high winds, rain or snow. We achieve this through using NASA satellite data, allowing SRJ to take a modern approach in giving our customers better standards.

Finance Options

At SRJ, we appreciate that a new home improvement project can leave you worrying about the cost. That’s why we offer our Mountcastle customers a range of payment options to help you finance your sunroom, conservatory, windows, doors or roofline installation. Whether you would like to pay by card or cash, or choose one of our payment plans, we will find a payment option to meet your needs.


Our Guarantee To You

Once our team has installed the new double glazing product into your Mountcastle home, the excellent level of customer service you will receive does not finish there. After installation we will send you your SRJ Guarantee package, which provides you as a customer with the guarantee that all our conservatories, sunrooms, uPVC windows, doors and extensions will provide you with at least 10 years of quality service. Should anything go wrong with your product (which is highly unlikely), we will endeavour to fix it.
