Heritage Windows in Bromley and Dartford, to Maidstone and Sevenoaks
Combining traditional aesthetics with modern performance, heritage windows are an excellent replacement option for period properties as they tastefully replicate the natural wood grain of timber.

uPVC is the nation’s favoured window material choice, and it’s no wonder. It is more cost-effective than real timber because its streamlined manufacturing makes it readily available for use. However, it still offers exceptional performances. uPVC uses a multi-chambered frame which provides excellent levels of energy efficiency. This is because currents of air aren’t able to break through the separated chambers, so the warmth is retained and the draughts kept out. When paired with our advanced double glazing, heritage windows can achieve A+ energy ratings.
The uPVC frame is finished in an anti-fade coating, so they’ll stay looking like brand new for at least 35 years. Modern uPVC also won’t rust, fade or warp for its lifetime. It’s maintenance-free, so unlike timber which needs frequent upkeep, you’ll only need to wipe the frames down every so often to get rid of any debris.
We use only the highest-quality uPVC materials, so you can be sure that they’ll be extremely durable. They’ve been tested to harsh weather climates, and whether it be snowing, raining or window outside, they won’t succumb to tough conditions.
Timber effect windows for listed properties
We’ve previously installed many heritage window styles on period properties that have been granted planning approval where regulations usually restrict home improvements. This is because of the quality of the traditional features that we use which effortlessly replicate the real thing. We can easily product imitations your existing windows, so you can benefit from the upgraded performance. Alternatively, we can design a new heritage window style to add kerb appeal to your listed property.
Our uPVC timber effect windows are expertly hand crafted using traditional styling, and incorporate authentic wood grain finishes, mechanical joints and optional slimline astragal bars to retain the classic aesthetic. With such a close attention to detail, homeowners can’t even tell them apart from real wooden windows.

Whether you choose our flush sash casement windows or storm-proof casement heritage style, all our uPVC timber effect windows will improve your home’s heat retention. The stormproof range are A+ 13 energy rated, whilst our flush sash casements are A+11, because of their slightly thinner frames. Both of which use high-quality multi-chambered uPVC frames to keep your home at a comfortable temperature 365 days of the year. With U-values as low as 1.2 w/m2K achieved with our double glazing, you can be sure that energy wastage will be significantly reduced, and even save money on your heating bills.
Our heritage window collection can also be fitted with our pioneering triple glazing, which adds an extra pane of glass into the specification. This will offer 5x better thermal performance than a standard glazed window, and keep external noises out. Triple glazed flush sash windows are the ideal solution if you live in a busy area or are more exposed to tougher climates, such as the coast.
Keep your property secure with replacement heritage windows
Old and weak windows are more vulnerable to forced entry because they can be broken into much more easily. Don’t make your home an easy target by not upgrading your windows. Our modern uPVC windows are incredibly robust and won't deter over their lifetime, so you can be sure that your property is protected.
We fit all of our uPVC timber effect heritage windows with sophisticated locking features as standard, including multi-point locking systems. These bolt the window sash to the frame at several points which significantly increases their resilience. The windows have been tested to rigorous security standards, giving you peace of mind that your family are safe and secure. As they’re uniquely designed to each property, we can include additional security features for even further protection.
