Timber Windows Brent

Brent is a borough of contrasts. Brondesbury and Queen’s Park in the south have Victorian terraces and conservation area controls. Wembley and Kingsbury in the north are dominated by 1930s and 1940s semi-detached housing. And running through the middle is the North Circular — one of London’s busiest, loudest roads, making acoustic performance a genuine concern for any property within earshot.

Our timber windows are built to your measurements in pine, meranti, or oak. Factory-finished with our microporous paint system, delivered across the borough. We manufacture — your local fitter installs.

The southern wards — Brondesbury, Queen’s Park, Kilburn — have genuine period character. Victorian terraces with sash windows, some conservation area coverage under Brent Council. These properties need timber sashes that match the originals.

Further north, the inter-war housing around Wembley, Kingsbury, and Preston follows a consistent pattern: bay-fronted semis, often with original Crittall casement windows that are now 80-90 years old and well past their useful life. Flush casement timber windows suit these properties — the proportions match the original casement openings and the timber windows and energy efficiency improvement is dramatic.

Here’s something Brent homeowners frequently ask about: different colours inside and out. It’s more common than you might think — and for good reason.

Many Victorian terraces in Brondesbury maintain a white exterior to match the streetscape, but homeowners want a warmer interior finish — a soft grey, sage green, or heritage colour that works with their room décor. With conventional windows, you’re stuck with one colour both sides. Our factory-applied paint system offers dual-colour as a standard option.

How it works: we paint the exterior faces in your specified exterior colour (often RAL 9010 Pure White or similar) and the interior faces in a separate colour (any RAL or Farrow & Ball shade). The two colours meet at the frame edge, invisible when the window is viewed from either side.

No extra manufacturing time. Modest extra cost. Significantly better result than site-painting the interior after installation — which risks brush marks, uneven coverage, and paint on the glass.

If your Brent property is near the North Circular (A406), or along any of the borough’s busy trunk roads, acoustic performance matters as much as thermal performance.

Standard double glazinging reduces external noise by approximately 25-30 dB. For a road with average traffic, that’s usually adequate. But the North Circular isn’t average traffic — it’s continuous, heavy, and loud.

Triple glazing with an asymmetric cavity — different glass thicknesses on each side — reduces noise by 35-40 dB. The asymmetry matters because it prevents the two panes from resonating at the same frequency, which is what allows sound to pass through symmetric double glazing.

Timber frames help too. Wood is a natural sound insulator — its cellular structure absorbs vibration more effectively than the rigid aluminium or hollow uPVC profiles used in competing products. The combination of timber frame + asymmetric triple glazing is the most effective acoustic solution for a residential property.

We don’t push triple glazing on every order — for a quiet Brondesbury street it’s unnecessary. But for properties within 200 metres of the North Circular, or facing a busy junction, it changes daily life noticeably.

Sash — for Brondesbury/Queen’s Park Victorians. From ££449+VAT+VAT.
Casement — for Wembley/Kingsbury 1930s semis.
Georgian — for the occasional period property.

Standard glazing on a North Circular property. If you can hear traffic from inside with the windows closed, standard double glazing won’t fix it. Specify asymmetric triple for road-facing elevations.
Assuming all 1930s semis are identical. Wembley semis and Kingsbury semis were built by different developers with different specifications. Window sizes, bay angles, and cill heights vary. Measure your property, not the neighbour’s.

Choosing wrong style for inter-war vs Victorian. Victorian terraces in Brondesbury need sash windows. 1930s semis in Wembley need casement windows. Getting the style wrong looks anachronistic.

Can I have different colours inside and outside my windows?

Yes — our factory-applied dual-colour finish lets you specify one colour externally and another internally, at modest extra cost. Popular combination: white exterior with heritage colour inside.

Does triple glazing help with North Circular traffic noise?

Significantly. Asymmetric triple glazing reduces noise by 35-40 dB versus 25-30 dB for standard double glazing. For properties within 200m of the A406, the difference is noticeable day and night.

What window type suits 1930s Wembley semis?

Flush casement windows match the original Crittall casement proportions. They provide modern thermal performance and security with the correct period aesthetic. From £449+VAT.

Does Brent Council require timber windows?

In conservation areas (Mapesbury, Brondesbury, Queen’s Park), timber matching the originals is expected. Outside conservation areas, there’s more flexibility but timber remains the quality choice.

What’s the total cost for replacing windows on a Wembley semi?

A typical semi with 10-14 windows costs £4,500-£8,000+VAT in engineered pine with double glazing. Add roughly 15% for triple glazing on road-facing elevations.
