Cavity insulation for new builds and extensions for South Shields properties
We cover South Shields and the NE33 postcode district, including nearby Tynemouth, North Shields and Jarrow. It is around 7 miles east of Newcastle upon Tyne.
Where a South Shields property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. A suitable wall in South Shields is usually filled in a single day from outside, with drill holes made good to match the pointing.
Every elevation is judged on its own exposure. Tyne and Wear has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
On compliance, in South Shields filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

Extensions that join an older house
Where an extension meets an existing cavity wall, the junction is a weak point. We can borescope and fill the existing wall at the same time so the old and new walls perform together.
