Wall tie replacement for St Helens properties

We cover St Helens and the WA10 postcode district, including nearby Prescot, Huyton and Newton-le-Willows. It is about 11 miles east of Liverpool.

Damp in an insulated St Helens home is not always the insulation's fault, so the diagnosis comes before any extraction. We never cold-call in St Helens or anywhere else, and we do not work with doorstep claims companies.

Before any material is chosen, exposure is checked. Merseyside 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 the rules side, if cavity wall insulation follows in St Helens, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Ties and cavity insulation

Ties should be checked before a cavity is filled. Fitting remedial ties does not normally stop a cavity being insulated later, and we can do both in one visit. Where cracking suggests movement, we recommend a structural engineer's view first.

What is included in St Helens
