Too many people choose windows on price alone. This never delivers great quality; owners invariably end up with products that quickly fall apart or degrade their home’s character.
Your customers will find that we have created authentic products that are far more secure, thermally efficient, and require substantially less maintenance than their existing windows. They have a range of choices and can decide which of our three Classic sash windows best match their needs.
As a trade installer buying sash windows for clients, you will appreciate the comprehensive range of colours, styles, and designs you can offer. This will provide them with real choice, along with sensible pricing, delivered to you free on the UK mainland, on time and in full.
Finding trustworthy suppliers and installers can be a daunting prospect. Purchasing windows isn’t something you do every day so it can be confusing when every company is claiming their products are the best.
Most people would like beautiful, real sash windows that are secure and energy-efficient, however, they have to look right and the workmanship must meet your expectations. Homeowners want the best windows they can afford, so it’s important to explain why sash windows are more expensive than casements:
So if you are changing windows in your home, it is vital you understand what is being offered within the prices you are quoted because you may find someone who is cutting corners, offering casements, rushing the fitting or who lacks any passion for your property.
Most people appreciate that quality products generally cost a little more; using careful installers who take more time is slightly more expensive. Windows that incorporate prettier finishes, better insulation and stronger furniture cost more than standard styles.
As an installer or homeowner, you can be assured that these windows will work. They are robust, well-constructed and renowned for reliability, so you’ll avoid service calls.
We never stop making improvements. Through a continuous commitment to innovation, we’ve come up with some pioneering techniques in crafting the best sash windows. We design novel new components like foam draught baffles, foam cill pads, Georgi® clips, and balance retaining clips to crack previously problematic production flaws.
