What our customers have to say...
Right now, your windows are probably:
- Leaving you on display to neighbours or the street when you want privacy
- Throwing blinding glare across your TV, couch or workspace
- Highlighting dust, fingerprints and streaks every time the sun moves.
- Forcing you to keep good furniture away from windows to avoid fading.
- Creating hot spots near glass while the rest of the home feels reasonable.
Without the right control, you end up choosing between view, light, privacy and comfort – instead of having all four.
How Venetian Blinds Will Change Your Space
- With the right Venetian blinds, those same windows can:
- Let in natural light without the harshness, using simple tilt control
- Maintain views while cutting direct sun before it hits the glass
- Give you privacy when you want it, openness when you don’t
- Add a clean, architectural look from the outside and a warm, finished feel inside
You still get daylight and outlook. You just gain precise control over how the glass behaves at different times of day and year.

FAQs
Do external venetians really help with heat
Yes. Because they shade the glass from the outside, they significantly reduce solar heat gain compared with only treating the inside of the window. That can help keep rooms cooler and reduce reliance on air conditioning, especially on large or highly exposed glazing.
How long do external Venetian blinds last?
The lifespan of Venetian blinds depends on the material, where they’re installed and how they’re used. High-quality Venetian blinds, correctly matched to the space and maintained with simple, routine cleaning, are designed to provide a long-lasting window furnishing rather than a short-term solution. During your consultation, we’ll explain what you may realistically expect based on your chosen material and the conditions in your home.
Are Venetian blinds safe for children and pets?
Modern Venetians are supplied with safety features to meet current standards, including fixed or tensioned cords and clear guidelines on installation height. We can also discuss cordless or motorised options for certain windows if you want to minimise cord access in kids’ rooms and main living spaces.
What’s the difference between indoor Venetians and external venetians?
Indoor Venetians sit inside the room and focus on light, privacy and appearance. External venetians sit on the outside of the building and focus on stopping heat and glare before they hit the glass, which can make a big difference on large north and west‑facing windows.
Are Venetians OK for bathrooms and kitchens?
Yes, as long as you choose the right material. Real timber is better kept for dry areas. For bathrooms, laundries and many kitchens we usually recommend faux wood Venetians, which are made from moisture‑resistant materials and handle steam and splashes far better over time.
