Timber glazing upgrades in Portishead
If you are looking at Misted Unit Replacement in Portishead, the timber is only half the decision. With Georgian Clifton terraces, Victorian bay-fronted streets and converted warehouses making up much of the area, off-the-shelf sizes rarely line up. Then there is mild wet westerly weather with limited hard frost, which reliably produces moss and algae growth followed by paint blistering on shaded elevations given enough seasons. Everything we do here comes back to swapping the failed unit rather than selling you a whole window.
A surveyor visits first and records the real dimensions, at several points on each opening. Ask us for a figure and you will get one, with the lead time stated alongside it.
One thing that catches people out here: Clifton's Georgian stock frequently requires exact sash box replication.

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

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.
