DWC Trade Windows

Effortless solutions for windows and doors

Everyone hates trickle vents.

We get asked to leave them off every single week. People think they ruin the look of a brand-new window.

We always say no.

The Law

We don’t write the building regs. But we won’t fit illegal windows just to get a sale.

The law changed. You need vents. A bloke in a van might agree to leave them off for you. He takes your cash and vanishes.

You try to sell the house five years later. The surveyor spots the missing vents. You fail the check and end up paying to fix it anyway.

The Mould Issue

There is a real reason for the rule.

Old timber and 1980s plastic windows leaked air. The draughts were awful. But those draughts kept the house dry.

Modern windows seal completely tight. They trap everything inside.

Cooking, showering, and drying clothes creates moisture. With airtight windows, that damp air has nowhere to go. It hits the cold walls. You wake up to soaking wet glass. A month later, you have black mould growing in the bedroom corners.

Let It Breathe

The vents stop the damp.

They let a tiny bit of air circulate. The house breathes. You keep the heat inside, but the moisture gets out. Your walls stay dry. You never have to wipe down the glass in the morning.

They Blend In

Forget those massive white plastic blocks from the 90s.

Modern vents are colour-matched. You order Anthracite Grey frames, you get flat grey vents. They blend right into the frame. You stop noticing them after a couple of days.

Don’t let a cowboy fit illegal windows. Come down to 78 Alma Road. Look at our display models and see what the modern vents actually look like, or give us a call on 01202 533126.
