New build and renovation air conditioning in St Albans
For new St Albans extensions with flat roofs, the outdoor unit position is best agreed against the architect's drawings. Long sunny spells in the East of England put conservatories and top-floor rooms under real pressure.
First-fix pipework in St Albans extensions goes in while the joists and studs are open. St Albans lies roughly 7 miles from Watford, and we cover it as part of Hertfordshire. That includes the AL1 and AL3 postcode districts.
