Leaking in The Stow? Boiler installs sorted properly

We respond fast, find the actual source (not just where the water shows), and fix it properly — soldered or pressed copper, never just a clamp. For full installs in The Stow we'll size the boiler against your real demand, not just like-for-like swap whatever's on the wall.

Learn moreAbout The Stow
Original new-town neighbourhood centre. Many original 1960s flats with undersized gas supplies that we've upgraded over the years.
Predominantly 1950s–70s post-war housing with a mix of terraces, semis, and 60s-built flats. Pockets of older stock around Old Harlow.
- Original 1960s flats often have undersized gas supply pipes that limit modern combi performance
- Older Old Harlow properties frequently have low mains water pressure that affects combi choice
- Many 60s/70s back boilers still in service — our regular work involves removing these and reinstating fireplaces

Quick answers on boiler installs in The Stow
Where do boiler leaks usually come from?▾
Most common: pressure relief valve discharging because system pressure is too high, a perished pump seal, or a failing heat exchanger on older units. We diagnose properly rather than guess.
Should I turn the boiler off?▾
If water is actively dripping and you can see it pooling, yes — switch the boiler off at the spur, and turn the system pressure down via the filling loop if you can. Then call us.
Do you take the old boiler away?▾
Yes — old boiler, packaging and any redundant parts are removed and disposed of properly at no extra cost.
Which boiler brand do you recommend?▾
Worcester Bosch and Vaillant for long warranties and parts availability; Ideal Logic Max for budget-conscious installs. We'll explain trade-offs honestly.
