Everyday plumbing and heating for Darnall's older housing
Darnall sits in the east of Sheffield, roughly two and a half miles from the city centre, bordering Attercliffe, Tinsley, Carbrook and Handsworth. It grew with the railways and the Don Valley steel industry — Darnall railway station opened in 1849 — and the housing that went up alongside that industry is still the bulk of what stands today.
The housing here is mixed. Alongside the small terraced streets and later steelworkers' cottages there are inter-war private semis and a good deal of council-built housing, so no two jobs on the same street are necessarily the same. What most of it has in common is age: heating systems that have been repaired and part-upgraded over many years, original waste runs, and pipework that has had a lot asked of it.
That is the work we are called out to in S9 most often. A boiler that keeps cutting out, a radiator circuit that never quite balances, a leak under a floor, or a drain that backs up every time there is heavy rain. We also do a lot of work for landlords and tenants here — gas safety checks, boiler servicing between tenancies and repairs booked around the people actually living in the property. Every gas job is carried out by a Gas Safe registered engineer and we explain what we have found before we start.

“Needed a new boiler installed asap, got in contact with Ricky. Straight away he quoted & fitted me in quickly. The lads stayed for 10 plus hours and returned the next day to ensure I had water and heating. Can't fault the lads at all.”
“Great service, responded quickly and sorted my boiler out so I had heating and hot water back on in this freezing weather. Came out late on a Saturday night to fix. NHS discount too!!”
“Thank you to Rick and the team for fitting our new boiler and radiators. I waited a while before leaving a review, but 6 months down the line it's still working just as good. I would highly recommend.”

The drain outside our terraced house keeps backing up — is that ours to sort?
It depends where the blockage is. The pipework inside your property boundary is normally your responsibility, while shared sewers and the public sewer beyond it usually sit with the water company. In older terraced streets several houses often drain into one shared run, which is why a blockage can affect more than one property. We can clear the blockage and tell you what we found, so you know which side of that line it falls on.
Our house still has old steel or lead pipework in places — should it be replaced?
Older properties in S9 often have a patchwork of pipe materials added over the decades. Ageing steel pipework corrodes internally and narrows, which is a common cause of poor flow, and older lead supply pipe is generally worth replacing when the opportunity arises. We will show you what is actually there, tell you which sections are causing you problems now, and give you a sensible order to tackle them in rather than ripping everything out at once.
Our boiler is in an awkward spot — a cellar head or a kitchen cupboard. Can it still be replaced?
Usually, yes. What matters is that the new appliance can be sited safely with the right ventilation, a compliant flue route and enough access to service it in future. Sometimes the sensible answer is to replace it where it is; sometimes it is better to move it. We will survey the position first and tell you honestly which of those applies before anything is ordered.
The stopcock is seized and we cannot turn the water off — what should we do?
If water is escaping, call us straight away on 07534 793949 and we will get to you. In the meantime, if you can find the external stop tap in the pavement or footpath outside, that will often isolate the supply. A seized internal stopcock is very common in older houses and it is worth having replaced before you need it — it is a short job when nothing is going wrong and a much bigger problem when it is.
How far east do you cover — do you go out to Tinsley and Handsworth?
Yes. As well as Darnall we work across Attercliffe, Tinsley, Carbrook, Brightside, Wincobank, Handsworth, Woodhouse, Richmond, Intake and the Manor, plus the rest of Sheffield and out into Rotherham. If you are nearby and not certain, give us a call and we will tell you straight away.
