Wall tie replacement for Flint properties
If your property is in Flint or the CH6 district or nearby Deeside, Buckley and Hawarden, it is within our Clwyd coverage. It is roughly 15 miles north-west of Wrexham.
If your Flint installation has a guarantee, we check it first; the guarantee route may cover the work. Where a Flint wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up.
Local weather affects which walls can be filled. Parts of Clwyd face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.
As for paperwork, if cavity wall insulation follows in Flint, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

Signs of wall tie failure
Horizontal cracks in mortar joints at regular vertical intervals, bulging brickwork, or lifting of the roof verge. Older galvanised ties, especially in walls built before the 1980s, are the usual suspects.
