What is Twinplas guttering?
Twinplas is a twin-wall PVC box gutter made specifically to replace the timber trough gutters on Victorian and Edwardian terraces and barn conversions. It is the same shape and size as a wooden trough, so it sits in the same position at the top of the wall, but it cannot rot and never needs painting. It comes in 3, 5 and 6 metre lengths, weighs under 3 kg a metre, and is joined with sleeve connectors that carry factory-fitted rubber gasket seals.
Do you fit Twinplas guttering in Leeds?
Yes. Leeds has a great deal of Twinplas and timber trough guttering on its older terraced streets, and we fit and replace it right across the city, including Headingley, Chapel Allerton, Roundhay, Armley, Beeston and Horsforth. There is no minimum job size, from a single leaking run to a whole terrace, and the survey and written quote are free.
Do you fit Twinplas guttering in Beverley?
Yes. Armour Shield Roofing Services fits Twinplas guttering across Beverley (HU17), including Molescroft, Tickton and Walkington. In September 2026 we replaced the timber trough across two terraced houses near Queensgate with a 9-metre run of Twinplas, replacing the corbels beneath it first. The survey and written quote are free, and the work is done by our own directly employed team.
Do you fit Twinplas guttering in York?
Yes. We fit Twinplas guttering across York, where the Victorian terraces around Fishergate, South Bank and Heworth often still carry their original timber trough gutters. Within the city’s conservation areas we check what applies to your property first, and fit timber, cast iron, cast aluminium or lead where the original material has to be kept.
Do you fit Twinplas guttering in Sheffield?
Yes. We travel to Sheffield for Twinplas work of any size, including Crookes, Walkley, Nether Edge, Hillsborough and Sharrow. We survey the old trough and the corbels or brackets that carry it, then give you a fixed written quote before any work starts.
Which parts of Yorkshire do you cover for Twinplas, and is there a minimum job size?
We fit Twinplas anywhere in Yorkshire, including Leeds, York, Sheffield, Wakefield, Huddersfield, Halifax, Doncaster, Harrogate, Hull, Scarborough, Beverley and the East Riding. There is no minimum job size: we will replace one short run, a single house or a whole terrace, and the survey and written quote are free wherever you are.
Can a timber trough gutter be replaced with ordinary plastic guttering?
Usually not. Ordinary half-round or square uPVC guttering hangs from a fascia board on clips, and a terrace built with a timber trough normally has no fascia — the trough rests at the top of the wall on corbels or brackets. Twinplas is a box profile made to go where the trough was, so the roof edge does not have to be altered.
Should I repair my timber trough or replace it with Twinplas?
If the timber is still sound, a trough can be repaired and relined. If it is soft, sagging or leaking along its length, replacement is the better money. A new timber trough keeps the original material, which a listing may require; Twinplas gives the same look from the street with no rot and no painting.
Does Twinplas need any maintenance?
Very little. It is PVC, so there is nothing to rot, rust or repaint. Like any gutter it should be cleared of leaves and moss once or twice a year so the outlets and downpipes stay open.
Do I need permission to fit Twinplas in a conservation area?
On an ordinary house, no. On a listed building, changing the gutter material needs listed building consent, and in a conservation area an Article 4 direction can restrict changes to the front of a house. Much of central Beverley and York is covered by conservation areas, so we check what applies before you commit, and fit timber, cast iron, cast aluminium or lead where the original material has to stay.
How much does Twinplas guttering cost?
As a guide, replacing a timber trough with Twinplas costs around £1,000 per side of a terraced house — front or back — supplied and fitted, including removing the old trough. Replacing the corbels or brackets beneath it, or renewing downpipes, adds to that, and we price the whole job fixed in writing after a free survey.
Is Twinplas guaranteed?
Our workmanship on every Twinplas installation is covered by our written guarantee, and we carry £5 million public liability insurance. The gutter itself is PVC with nothing to rot or rust, so there is no repainting cycle to keep up.
