Six weeks, two evenings a week, and a finished piece of work at the end of it. No prior experience assumed.
What you will need
Worth doing before you call anybody out, and it costs nothing.
About 20 minutesTurn the heating off
Let the system cool completely, or you will be bled on by very hot water.

Find the valve
Top corner of the radiator, a small square socket facing sideways.

Open it a quarter turn
Hold a cloth under it. You will hear air. Stop when water arrives.

Check the pressure
Bleeding drops it. Top the boiler back up to the mark on the gauge.

Which course is yours
Based on the four quotes our customers most often show us. Checked October 2026.

They found a leak two other companies had missed, fixed it the same week, and the invoice matched the quote to the dollar. I have already sent my sister to them.
