Replace Old Windows with UPVC Sash Windows
We specialise in replacing old, deteriorating windows with modern, energy-efficient uPVC sash windows.
If your home has old or damaged sash windows, you may notice common problems such as rotting sills, draughts, or inefficient insulation. Traditional wooden sash windows, while charming, often suffer from issues like paint failure, water penetration, and even fungal or insect attacks.
These problems can worsen over time, leaving your windows less effective at keeping your home warm and secure.
Why Replace Wooden Sash Windows?
Wooden sash windows can add a classic look to your property, but they require a lot of maintenance. Over time, paintwork fades or cracks, allowing moisture to seep into the wood. This not only causes the timber to rot but also increases the risk of structural damage.
In addition, old wooden windows tend to offer poor insulation, meaning higher energy bills and a colder home in winter.
By upgrading to sash upvc windows, you get the benefits of modern materials without sacrificing the traditional aesthetic. uPVC is durable, low-maintenance, and highly resistant to rot, unlike timber, which requires frequent repainting and repairs.
