Boiler Servicing & Repairs in Guildford
Gas Safe registered (reg. 197524) — local team covering GU1, GU2, GU3, GU4, GU5 and surrounding areas.
Guildford water hammers boilers in ways that Farnborough water doesn't. Limescale builds on the primary heat exchanger, sludge collects in the magnetic filter, and unprotected systems can lose 15-20% of output between one service and the next. Our annual service in Guildford always includes a scale check on the heat exchanger and a proper magnetic filter clean — not just a quick wipe.
Why this matters in Guildford
If you've had a boiler installed in Guildford by another company without a scale reducer and a magnetic filter, expect heat exchanger replacement to come up sooner than it should — often in years 6-8 rather than 12-15. We'll fit retrofitted protection on the service visit if your system doesn't have it yet.

Boiler Servicing & Repairs in Guildford — common questions
My Guildford boiler is making rumbling noises — is that bad?+
Yes — almost always it's limescale on the primary heat exchanger (kettling) and it gets worse, not better. A power flush plus a scale reducer plus a magnetic filter often fixes it. If the exchanger is already badly scaled, replacement is the only proper answer, and we'll quote honestly either way.
