Wall tie replacement across Hertfordshire

We cover 17 towns in Hertfordshire, including Watford, Hemel Hempstead, Stevenage, St Albans, Welwyn Garden City and more.

Every elevation is judged on its own exposure. Much of Hertfordshire sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.

If your Hertfordshire installation has a guarantee, we check it first; the guarantee route may cover the work. We never cold-call in Hertfordshire or anywhere else, and we do not work with doorstep claims companies.

Building Regulations in England

Filling an existing cavity wall is notifiable building work in England. Either a building notice goes to building control before the work, or the installer self-certifies it through a government-approved competent person scheme such as CIGA's CWISC scheme. The insulation used must also be suitable for the wall it goes into, which is why the survey checks construction, condition and exposure first.

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.
