Cutting Energy Costs Across the UK
With prices on the rise, homeowners everywhere are looking for ways to reduce their bills. Our low-E double glazing and argon-filled glass units help you cut down energy loss by up to 25%, keeping your home warm in places like Newcastle or chilly coastal towns like Brighton.
Built to Handle British Weather
Our frames and seals are designed to withstand the UK’s infamous rain and wind. Whether you’re in a damp rural cottage in the Lake District or a windy flat overlooking the Thames, we’ll ensure your windows stay airtight and draught-free.


Our Approach to Installing Casement Windows
Every installation we perform follows a precise and methodical process, ensuring we get each detail right. We focus on achieving the best outcome for your home’s comfort, safety, and energy efficiency. For instance, our Energy Efficient Glass Installation is designed to reduce heat loss, lower energy bills, and create a more sustainable living environment.
We have experience working on diverse UK properties, from narrow Victorian terraces in Leeds to sprawling homes in Somerset. Our team is equipped to address the challenges posed by various building types, ensuring every project, whether it’s Bay and Bow Window Installation or upgrading to energy-efficient solutions, is completed smoothly and to the highest standards.
1. Accurate Surveys and Preparations
Before starting, we take correct measurements of your existing openings using laser-guided tools. This allows us to ensure a snug fit, even in properties with older brickwork or uneven timber frames, common in areas like York or Cambridge.
2. Installation You Can Count On
Our fitters use anti-corrosion screws, expanding foam, and specialized fixings to ensure a secure fit that resists the damp British climate. For older properties, we take extra care to protect existing plaster or stonework during the installation.
3. Glazing and Hardware Setup
We install low-E glass units with reinforced edges for durability and improved thermal performance. Handles and locks are tested rigorously, meeting UK security standards.
4. Final Touches and Sealing
Once everything is in place, we seal all edges using UK-grade silicone that expands and contracts with temperature changes, preventing leaks or cracks over time. We’ll even test the windows for airtightness before leaving the site.


Casement Window Options to Suit Every Property
We know that no two homes are alike. That’s why we offer a range of customization options to match your property’s needs, whether you’re upgrading an Edwardian townhouse or modernizing a bungalow in Kent.
