One list, no guesswork
£96 buys the diagnosis visit and no call out fee is added. If we clear the fault in that visit with no parts, you owe nothing further. If it needs a part, here is what it costs, fixed, and nothing is ordered until you say yes.

Reviews from homeowners across the North East.
Diagnosing the fault properly
Seaham is about 7 miles from our base in Houghton le Spring, around 15 to 20 minutes by road through Hetton le Hole and Murton. It is the first of the coastal towns on our patch, with Sunderland to the north and Peterlee to the south, and we also cover Hetton le Hole, Houghton le Spring and Washington inland.
The housing is a mix of pit terraces in Dawdon, Deneside and New Seaham, interwar and postwar estates at Parkside, and new builds at Seaham Garden Village. Near the coast, exposed flue terminals and outside fittings deserve a careful inspection because they see more weather than protected inland installations.
Hot-water problems can have several causes that feel similar at the tap: a restricted plate heat exchanger, a diverter valve not moving fully, a flow sensor fault or an issue with incoming flow. We measure rather than guess. Flow at the tap, temperature rise across the boiler and incoming pressure are checked alongside gas pressure under load, the flue and the safety devices. Water hardness varies by postcode, so we do not assume scale is the cause without evidence.
Common boiler faults we see in Seaham
The same symptom can come from several different components, so the useful local advantage is being nearby and diagnosing the appliance rather than guessing from a postcode.
Hot water running hot then cool
A restricted plate heat exchanger is one possibility, but so are a diverter valve, flow sensor or another control fault. If scale is suspected, the water supply and appliance are checked before recommending treatment. A guide to limescale and boilers explains why water hardness should be checked by postcode rather than assumed across a whole town.
One thing worth knowing: a power flush cleans the heating circuit. It is not automatically the answer to a domestic-hot-water fault inside a combi boiler.
Flue and external fittings near the coast
External terminals, clips and pipework on exposed properties can take more weather than protected inland installations. We inspect the flue and terminal as part of the diagnosis rather than replacing internal parts while an external problem is being missed.
Older terraces in Dawdon, Deneside and New Seaham
A lot of pipework in older streets is buried in solid floors or boxed in, so a small leak can go unseen for a long time. What you notice instead is a pressure gauge that keeps falling. The cause may be a leak, a failed expansion vessel or a relief valve letting water by, and we pin down which one before any money is spent.
Newer homes at Seaham Garden Village
Newer homes tend to have newer boilers, and some faults may still be covered by the manufacturer's warranty. Check your paperwork before you book, as the warranty may be the cheapest route. If the boiler is out of warranty, or the fault is not covered, we can help.
How the price works
The fault finding visit is £96, fixed, with no call out fee on top. After that comes one fixed price for the repair, agreed before any part is ordered. Our repair cost guide lists typical figures.
