What we do and how we do it
What makes Draught Sealing work in the UK is usually invisible once it is finished. Property here runs to a mix of period and modern stock, and each of those brings its own set of dimensions. The exposure here is the full range of UK exposure conditions, which is exactly the condition that causes coating failure followed by rot at the joints. What you are paying for is sealing the perimeter without making anything stiff to open.
The survey happens before manufacture, which is why our units fit without packing or trimming. Rough dimensions and a couple of photographs are enough for us to price it properly.
Worth knowing locally: specification should always be matched to local exposure.

- Factory-applied microporous finish in any RAL or heritage colour

Verified client, UK-wide“Half the cost of replacement and the rooms hold heat noticeably better.”
Verified client, UK-wide“They fitted trickle vents we had not thought about, which stopped the condensation.”

Frequently asked questions
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.
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.
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.
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.
Do you fit, or supply only?
Both. Supply-only is common for trade and contractor clients. For private clients we usually recommend supply and fit, because responsibility for the fit and the finish then sits in one place.
How do you handle glazing?
Standard double glazed units for most work, and slim-cavity units where a conservation officer has restricted sightlines. Single glazing with putty lines is available where the consent requires it.
What if the opening is out of square?
Most older openings are. The survey records the actual dimensions at several points and the unit is manufactured to suit, which is the main reason we survey rather than work from the sizes given over the phone.
