What we do and how we do it

The Trickle Vents and Ventilation we make for the UK is set out from a survey, not a size chart. You are mostly dealing with a mix of period and modern stock around here, so openings vary more than people expect. Because of the full range of UK exposure conditions, we see coating failure followed by rot at the joints more often here than in most of the country. In practice that means keeping background ventilation compliant once you seal a house up.

We would rather spend an hour surveying than a week correcting. A quick call or a photograph of the opening is usually enough to get you a price.

Something particular to this area: specification should always be matched to local exposure.

Specification

  • Engineered hardwood or slow-grown softwood, FSC certified
  • Factory-applied microporous finish in any RAL or heritage colour
  • Sealed units, slim-cavity units or single glazing with putty line
  • Manufactured to survey dimensions, not to a stock size chart
  • Delivered UK-wide with chain-of-custody paperwork

Keep the joinery you have

Upgrade performance without throwing away sound timber windows.

Cheaper than replacement

Typically a fraction of the cost of new units, with much of the benefit.

Measured before recommended

We find where the heat is actually going before suggesting a spend.

Ventilation kept compliant

What clients tell us

Feedback collected directly from completed projects. Full written references are available on request before you commit.

“The survey showed most of the loss was around the frames, not through the glass at all.”

“Half the cost of replacement and the rooms hold heat noticeably better.”

“They fitted trickle vents we had not thought about, which stopped the condensation.”

What happens next

Four steps from first call to installed joinery. No pressure at any stage.

  1. Thermal survey

    We identify where the losses actually are, which is often not the glass.

  2. Options and costs

    Retrofit, secondary or seals only, priced side by side.

  3. Installation

    Carried out in situ, room by room, with minimal disruption.

  4. Aftercare

    Ventilation checked and maintenance guidance left with you.

Frequently asked questions

How long does a typical order take?

Most made-to-size orders run six to ten weeks from survey to delivery. Conservation and heavily detailed work can take longer, and we confirm the lead time in writing at quotation rather than leaving it open.

Will the finish need maintaining?

A factory-applied microporous finish typically needs inspection every three to five years, sooner on exposed coastal elevations. Maintaining it is far cheaper than letting a coating fail and the timber take up water.

What guarantee do you provide?

Ten years on workmanship, covering manufacture and the factory-applied finish. Where we install, the installation is covered too. It is issued in writing with the handover paperwork.

Do you work in hardwood or softwood?

Both. Engineered hardwood is the default where movement or exposure is a concern, and slow-grown softwood is often the better value choice for painted work in sheltered positions. We will tell you which we would specify and why.

Do you deliver nationwide?

Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.

Do you take a deposit?

Not before the measured survey. A deposit is only requested once the survey is complete and you have approved the final schedule and price.

Can you match an existing profile?

Yes. If you can supply a section, a photograph with a rule in shot, or an old unit, we can replicate the profile. For conservation work this is usually the condition the planning officer will apply.
