When it comes to maintaining a property in South Devon, few home improvements offer as much immediate impact as updating your glazing. Whether you own a traditional cottage in the South Hams or a modern semi-detached house in the heart of Newton Abbot, your windows play a vital role in security, insulation, and the overall look of your home.
At Renaissance Conservatories, we are a family-run business with years of experience serving homeowners across Devon. We understand that deciding on a window replacement project is a significant investment. Our friendly, helpful team works with you through every stage to make sure you are 100% happy with the result, ensuring the job is completed on time to reduce disruption to your life.
In this guide, we will break down everything you need to know about modern glazing, from material choices to the specific challenges of living in a coastal county.

Why consider window replacement?
Many homeowners in Newton Abbot and the surrounding South Hams areas struggle with old windows that have reached the end of their functional life. The most definitive sign that your double glazing has “blown” is moisture trapped between the two panes of glass. This means the window has lost its thermal efficiency entirely and will no longer keep heat in or noise out effectively. Even without this sign however, if your windows were installed over 20 years ago, they are likely to be underperforming compared to modern products. This is due to advancements in technology over the past couple of decades.
Reducing energy bills
The most immediate benefit of window replacement is the improvement in thermal performance. According to the Energy Saving Trust, upgrading from single glazing to A-rated double glazing can save a typical semi-detached home up to £155 a year on energy bills. Modern units use low-emissivity (Low-E) glass and gas-filled chambers to trap heat inside during the winter and reflect it during the summer, keeping the temperature inside your home more stable. Even if you already have double glazing, updating windows from the 1990s or early 2000s will typically reduce heat loss by over 50%.
Increasing property value
First impressions matter, and if your property has wooden windows with peeling paint, or thick, white uPVC frames yellowing with age, you’ll be astonished by the difference an upgrade can make. New windows, along with a high-quality front door, provide instant kerb appeal, while the slimmer frames of modern windows let light flood into your rooms. For those in period properties, using sympathetic styles can add up to 10% to the value of their homes by preserving its historic character while providing modern comfort.
Improving home security
Security technology has moved forward significantly in recent years. Modern frames are designed with internal glazing beads, meaning the glass cannot be removed from the outside and multi-point locking systems that provide true peace of mind for you and your family.

Choosing the right style: sash vs. casement
One of the first decisions our expert team will help you with is choosing the opening style of your new windows. In Devon, we see a wide mix of architectural eras, and the right window should respect the building’s original design. If you’re unsure which style suits your home, our knowledgeable team offers professional, honest advice.
The classic appeal of sash windows
Sash windows are a hallmark of Georgian and Victorian architecture. They consist of two sliding panels that move vertically.
- The Advantage: They allow for excellent ventilation control (opening both the top and bottom creates a natural convection current) and are essential for maintaining the authentic look of older homes in areas like Totnes.
- Modern Twist: Unlike original timber versions that could rattle or stick, modern uPVC sash replacements offer smooth operation and high-performance weather seals.
The versatility of casement windows
Casement windows are attached to their frame by one or more hinges at the side. They are the most popular choice in the UK today.
- The Advantage: They offer the best possible seal against the wind, as the sash is pressed firmly against the frame when closed. Because they open outwards, they don’t take up internal space, making them ideal for kitchens or bathrooms.
- Design: They provide a clearer, unobstructed view of the South Devon landscape, perfect for homes overlooking the Teign Estuary or the Dartmoor foothills.

Comparing materials: uPVC vs aluminium
Deciding between uPVC and aluminium is often a matter of balancing budget, aesthetics, and the age of your property.
The benefits of uPVC
UPVC remains a trusted material for several reasons:
- Thermal Efficiency: uPVC is a natural insulator, making it excellent at keeping heat in.
- Low Maintenance: It does not rot, flake, or peel. A simple wipe down with soapy water once a year is usually all that is required.
- Cost-Effective: It generally offers a lower price point than metal or timber, allowing you to update your whole home for a fair price.
The benefits of aluminium
Aluminium has seen a massive rise in popularity in towns like Buckfastleigh and Newton Abbot, especially for contemporary renovations. While more expensive than uPVC, it offers a much longer lifespan, so it can be worth the initial outlay if you intend staying in your house for decades to come.
- Strength and Slim Lines: Aluminium is much stronger than uPVC. This means the frames can be much thinner, allowing for larger panes of glass and more natural light.
- Durability: It is incredibly resilient against the elements and can last 45 years or more outliving similar uPVC windows.
- Sustainability: Aluminium is infinitely recyclable, making it a “greener” choice for the environmentally conscious homeowner.

Specific challenges for coastal and rural South Devon
Living in the South Hams or near the coast brings unique environmental factors that homeowners in inland cities like Exeter might not face.
Salt corrosion
If you live near the coast in Paignton or the South Hams, salt spray is a constant factor. Salt is highly corrosive to metal components. When we carry out a window replacement project near the sea, we recommend hardware with high-grade stainless-steel coatings to prevent pitting and rust.
Wind loading
South Devon can experience high winds, especially during winter storms. Modern window frames must be installed with precision to ensure they can withstand “wind loading”—the pressure exerted by high-speed gusts. Our installation team ensures that every frame is securely anchored and sealed to prevent whistling or water ingress.
Customisation: making your windows unique
At Renaissance Conservatories, we believe your windows should reflect your personal style. We offer a wide range of customisation options, and you can view some of our recent installations in our gallery.
- Colour Palettes: While white remains a classic, we offer wood-effect foils that look like natural Rosewood and modern shades like Anthracite Grey or heritage shades such as Chartwell Green.
- Glass Options: From decorative leaded glass and Georgian bars to obscured glass for privacy, you can tailor the look of every room.
- Hardware: Choose window handles in chrome, brass, black, or satin finishes to match your interior decor.
- Integrated Blinds: For a truly modern look, we can install windows with blinds permanently sealed between the glass panes, keeping them dust-free.

Frequently Asked Questions
How long does a window replacement project take?
Most standard house replacements can be completed in 2 to 4 days. Our installation team works efficiently to ensure your home is secure and weather-tight at the end of every day, minimising the time your living space is disrupted.
Do new windows come with a guarantee?
Yes. All our installations come with a comprehensive 10-year guarantee. Because we are a trusted local business with years of experience, you can have peace of mind knowing that we will be here to help should you ever need us.
Will new windows stop condensation?
Internal condensation is often a result of poor ventilation, but modern windows with trickle vents help significantly. New double glazing also eliminates “cold spots” on the glass where moisture usually settles, helping to keep your home dry and healthy.
Can I replace my windows and front door at the same time?
Certainly. Many homeowners choose to update their front door alongside their windows to ensure a consistent colour match and to improve the overall security of their home in one go.
