Alexander Windows

Alexander Windows was founded in 1991 with a vision to create a trustworthy, reliable service for homeowners looking to invest in industry-leading products. We wanted to do things differently, offering tailor-made windows and doors with no pressure selling, no gimmicks, and unparalleled customer service. Almost 30 years on, and we'd like to think we've done just that. Many of our customers come back to us time and time again, recommending us to friends, family and colleagues along the way. We believe in quality, sustainable products.

Increase your living space with one of our low maintenance, highly insulated composite garden studios. Installed in as little as 3 days and perfect for a number of different uses, our studios offer the perfect solution. Constructed from high performance composite wood, our range of studios are low maintenance, sturdy and versatile. Available in a range of styles and sizes, allowing you to make use of your outdoor space all year. Choose from single or dual authentic wood tones, embossed with a woodgrain effect that looks and feels just like real timber.

Helping people realise their dreams for their homes has been our passion since 1991. One of our resident GuardianTM Warm Roof specialists will visit you in your home to discuss how you would like to use your space before coming away and preparing a quotation. We don't pressure sell, so relax! The GuardianTM Warm Roof system has taken the home improvement industry by storm, and for good reason. Our installers are all GuardianTM approved, employed directly by us, and work to the highest possible standards.

Our glass conservatory roofs are the perfect solution for those looking to use their conservatory more whilst flooding their home with natural light. The high-performance nature of the glass we use ensures that your conservatory will be warmer in winter and cooler in summer. A glass conservatory roof can replace most traditional polycarbonate roofs in as little as a day, or can be part of a complete replacement conservatory. Our glass conservatory roofs are designed by us for your home. They can be manufactured in a range of styles and colours, from simple white to class Rosewood, and even grey for those looking for something more contemporary.

Our range of Timber Alternative doors is inspired by styles that would typically be found in a period property. We understand our customers' desires to stay faithful to the age of a property whilst enjoying the security and warmth provided by modern materials. Choose from a range of solid and glazed styles, all of which benefit from the traditional look of mechanical joints and the strength of uPVC. Our range of Timber Alternative doors is available in a choice of finishes that complement these traditional styles.

Choosing the right door for your home isn't easy, and choosing the right company to carry out the work for you can be even more difficult. With Alexander Windows, you can relax. All of our uPVC doors are designed by us and fabricated using the best profile, locks and glass. We also employ our own, time-served joiners ensuring the best standard of installation possible. Our online brochure will guide you through the different uPVC door styles and optional extras, and will also tell you a little about improved security, noise reduction and energy efficiency.

When it comes to changing your casement windows, we understand you have a wide choice of options. So what makes us different? Well, we've been trading non-stop since 1991. We've transformed over 100,000 homes, and gained the coveted support of Trading Standards. We employ our own installers, don't pressure sell and have a dedicated Customer Service department to look after you once everything has been finished. Every window that we install is made to suit every individual customer's home. We use industry-leading Kmmerling windows, the best energy-efficient glass on the market, and locks that will keep you and your family safe.

We have been installing Rockdoors for over fifteen years and honestly believe they are the best doors on the market. They are strong, thermally efficient, and gorgeous to look at. That's why we have them in our own homes. We have been installing Rockdoor composite doors since their foundation in 1996. We have thousands of installations under our belts, and can confidently say that Rockdoor is one of the best composite doors on the market. Year on year, they prove to be a popular choice among our customers.

Alexander Windows has over 25 years' experience in the manufacture and supply of uPVC windows. We have an unrivalled knowledge of our products, backed by experience and a passion for what we do. We don't just sell industry-leading windows, we sell peace of mind. We will listen to your reasons for upgrading your windows, recommend products, carefully draw and cost each frame and send it to you for your consideration. We don't door knock, pressure sell or use gimmicks. Over the years, we have found that our products and service sell themselves.

We have always found uPVC bay and bow windows to be very popular, probably because they add light and space to create a bright airy ambiance. Whether you're replacing an existing bow or bay window or would like to convert a flat window, we'll be able to talk you through your options. Our bay and bow windows are available in a range of colours, including classic white, rosewood, oak, grey and more. These colours can be teamed with lead work, Georgian bar or fancy bevelled glass designs. Your replacement windows will be made-to-measure for your home, so you can be as creative or traditional as you like.

French doors can make a superb addition to your home, providing a wider opening than standard doors and allowing maximum light and ventilation. We offer uPVC, Rockdoor and Solidor French doors, all of which are available in a range of colours and configurations, including fully glazed, Georgian bar, square lead or diamond lead. They can open either outwards or inwards and can be made with side panels and/or fanlights. The double handle feature of our French doors affords a well balanced and symmetrical look, while the toughened safety glass provides excellent security.

A popular space-saving alternative to French doors, our inline patio doors allow you to enjoy views of your garden or patio all year long, whilst also benefiting from warmth and security. Our patio doors are available in a range of finishes, including rosewood, golden oak, cream, and black and make a handsome addition to any home. Helping you to protect your home has always been important to us. For this reason, we only install Secured By Design inline patio doors. They are rigorously tested and are actively recommended by the police.

Our aluminium bifold doors offer homeowners a flexible, tailored solution. Consider opening a whole wall of your home and enjoying the garden view, safe in the knowledge that your home is insulated and protected to the highest possible standard. The unique design of our bifold doors means both cill and track are incorporated into the threshold, which results in a reduced frame height for improved aesthetics and a smoother operation of opening and closing. As a popular alternative to more traditional uPVC French doors and uPVC sliding patio doors, aluminium bifold doors create an open plan feel blending your living space seamlessly with your garden.

For many people who love their conservatory, it's a fair bet that if they could change one thing it would be to have an even temperature all year round. Until recently, temperature had to be controlled by blinds in the summer and expensive heaters in the winter. There is now an elegant solution which not only provides a pleasant temperature all year round, but becomes an integral part of your home overnight. With a lightweight, solid GuardianTM Warm Roof, your conservatory will be fully insulated, soundproofed and become a place in your home that you can enjoy all year.

We source, design and install some of the most trusted names in the glazing world. Whether your focus is on style, security, heat retention, or all three, we will have a product that is just right for you. Solidor composite doors offer one of the largest range of composite door colours and styles available. Whether you're looking for a traditional door to suit a stone property or something modern for a newer property, Solidor will have a design that suits your homes perfectly. Alongside their broad range of styles and colours, Solidor's range of door furniture is also incredibly comprehensive.

Conservatories have come a long way over recent years, with new developments allowing homeowners to enjoy their favourite room all year round.
