Leak detection and regassing in Willesden
Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell. Flare joints are a frequent leak point on older split systems, so they are among the first things checked on a visit in Willesden.
If a system in Willesden has needed gas before, the original leak was probably never fixed. Our London coverage takes in Willesden, about 5 miles from central London. Postcode districts we cover here include NW10.
