Repointing and pre-insulation repairs in Hertfordshire

Pre-insulation repairs put right the defects that let rain into a wall, so it can be filled safely: failed pointing, spalled bricks, cracked sills and render, and leaking gutters and downpipes. Our Hertfordshire coverage includes St Albans, Hemel Hempstead, Stevenage and the towns around them.

Repointing and pre-insulation repairs across Hertfordshire

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

Local weather affects which walls can be filled. 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.

Where a Hertfordshire 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. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Hertfordshire properties, so you can choose who fixes them.

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.

Why repairs come first

Energy Saving Trust advice is to fix brickwork, pointing, roofs, gutters and downpipes before filling. A filled cavity is less forgiving of a wet outer leaf than an empty one, so we price repairs separately and you choose who carries them out.
