Clevedon is one of the best spots on the Bristol Channel for a sea view. But that coastal position comes with a trade-off: salty air, strong gales and window frames that take a beating.
Aluminium windows, are a great choice for this stretch of coast, built to cope with harsh weather conditions and give you the sea views you moved here for.

Key takeaways:
- Salt air is tough on weak frames, but aluminium holds firm
- Aluminium is naturally rust-resistant, so it keeps its shape for years
- Slimmer frames mean more glass and a clearer view
- Low maintenance: a soft cloth and warm water keep them looking their best
At DM Windows, we manufacture aluminium windows at our own factory in Bristol, so we see first-hand how well this material performs in demanding coastal settings.
What Clevedon’s coastal climate does to your windows
Living by the coast has its perks, but your home also has more to contend with than one set back from the water, including:
- Salty air that speeds up corrosion in poor-quality metal fittings and frames
- Strong coastal winds that put constant pressure on frames, hinges and other moving parts
- Sharp changes in temperature, from hot south-facing glass to damp winter cold, stress weaker materials
Timber can swell and rot in these conditions, and uPVC windows can discolour under strong UV and salt exposure. The right window frame matters here and aluminium is the material that stands strong alongside your property, whatever the coast throws at it.
The benefits of aluminium windows for a coastal property
Strength and rust-resistance you can rely on
The strength of aluminium is one of its defining features and aluminium window frames resist rust naturally. A factory-applied powder coating adds a further layer of protection against salty air, giving aluminium frames decades of use. The lifespan of aluminium windows can outlast timber or uPVC, backed by our guarantee of up to 20 years.
Slim sightlines for uninterrupted sea views
Aluminium is strong enough that frames can be made much slimmer than timber or uPVC without losing structural integrity. That means slim sightlines, large glass panels and more natural light in every room. Our casement windows and flush casement windows are a popular choice with homeowners who want a sleek appearance and as little frame as possible, maximising those coastal views.
Energy efficiency that keeps bills down
Modern aluminium windows use thermal break technology, built-in thermal breaks that interrupt heat transfer between inside and outside, cutting heat loss. That keeps energy bills down whatever the season. All our windows also come with double glazing or triple glazing, useful for noise reduction if you live close to a busy coastal road.
Aluminium windows or uPVC windows: key factors to weigh up
Each material has its benefits, and the right choice depends on your home. uPVC windows are a popular choice for their affordable price point, but aluminium wins out on frame strength, sightlines and how well it withstands extreme temperatures and salty air.

How long do aluminium windows last in a coastal climate?
With proper care and CERTASS-approved installation, aluminium windows can last 45 years or more, even in a coastal setting like Clevedon. Their rust-resistant frames and powder coating cope well with salty air, giving you long-term performance and peace of mind.
Keeping your aluminium windows in top condition
Aluminium windows are low maintenance by design, especially near the coast, where salt residue builds up on frames and glass. A little regular maintenance keeps your windows looking their best:
- Soft cloth and warm water, every few weeks, to shift salt deposits
- Mild detergent for anything stubborn, then a rinse with clean water
- Moving parts, hinges, handles and locks: a little oil every few months keeps them in smooth operation.
Regular cleaning like this protects the aesthetic appeal of your windows and is minimal compared to sanding, filling and repainting that timber frames demand.
