Our Range of Sash Windows in Clapham

Timber Sash Windows in Clapham

Our timber sash windows are ideal for homeowners who value the natural look and durability of wood. Crafted from sustainably sourced, FSC-certified timber, these windows are perfect for maintaining the authenticity of period properties.

uPVC Sash Windows in Clapham

For those looking for a low-maintenance alternative, we also offer uPVC sash windows, which mimic the appearance of traditional timber but with the added benefit of being easy to care for and more affordable.

Double Glazed Sash Windows in Clapham

Our range includes double-glazed and triple-glazed sash windows, offering excellent insulation against both noise and heat loss. Double glazing is a popular choice for improving energy efficiency and reducing external noise, while triple glazing provides an additional layer of insulation, ideal for properties in busy areas.

All our glazing options meet current building regulations for thermal performance, helping you cut down on energy bills while staying comfortable year-round.

Customisation Options for Clapham Homes

You can choose between timber or uPVC frames, depending on your aesthetic preferences and maintenance requirements. For finishes, we offer a variety of paint and stain options to match the look of your home, from classic white to rich wood tones.

We also provide several hardware options, including polished chrome, brass, and antique finishes for handles, locks, and other fittings. For those seeking a more traditional look, you can add decorative glazing bars and run-through horns, which are perfect for maintaining the original appearance of period properties.

Sash Windows for Traditional Clapham Homes

For listed buildings and homes in conservation areas, we provide heritage sash windows. These windows are designed to match the original style of your home while incorporating modern glazing options to improve energy efficiency. They feature period detailing such as run-through horns, lambs tongue mouldings, and slim frames that comply with strict conservation requirements, ensuring your property retains its historical character.

Bespoke Options Available in Clapham

We also provide fully bespoke sash windows, allowing you to choose from a variety of finishes and hardware. Select from traditional cord & weights mechanisms for a classic feel or opt for spiral balance systems, which offer a smoother, more modern operation. Our customisation options include different glazing bars, decorative horns, and a wide range of colours, ensuring your windows are tailored to your preferences and property style.

Our Window Installation Process from Start to Finish

We provide a seamless, stress-free experience from your initial enquiry to the final window installation:

1. It all begins with a free, no-obligation survey, where one of our experts will visit your property in Clapham to assess your requirements. We’ll discuss your preferences, examine the architectural details, and recommend the best sash window options based on the specific characteristics of your home.

2. Once the survey is complete, we move on to the bespoke manufacturing process. Each window is made to order, designed to fit perfectly into your property while meeting both aesthetic and practical needs.
   
3. When it’s time for installation, our FENSA-certified team ensures everything is fitted to the highest standards. Then, after installation, we provide full aftercare support, including guidance on maintenance to keep your windows looking and functioning their best.

Energy Efficiency & Sustainability – Why We Stand Out

We prioritise energy efficiency and sustainability in every window we design and install. Our sash windows are built to keep your home comfortable while reducing energy consumption, making them an excellent choice for eco-conscious homeowners in Clapham.

Our windows are equipped with Low-E glass (low emissivity), which reflects heat back into your home, keeping it warmer in the winter and cooler in the summer. Combined with warm edge spacers and argon-filled glazing, these features minimise heat loss and improve insulation, reducing your reliance on heating and cooling systems.

We are also committed to using FSC-certified timber, ensuring that all the wood we source comes from responsibly managed forests. By choosing sustainable materials, we help protect natural resources while providing long-lasting, high-quality windows.
