Gas Boiler Repairs in Windsor

For a straightforward like-for-like repair, consent is not usually required. However, if the work involves moving the boiler to a new position, changing the flue route, adding external pipework, or altering the fabric of a listed building in any way, listed building consent is likely needed. We advise on this during our initial assessment and can guide you through the process if consent is required.

In Windsor's older properties, pressure loss commonly stems from two sources. First, the hard water at 290mg/l damages seals and valves within the boiler over time. Second, original lead supply pipes and aged copper pipework in Georgian and Victorian buildings develop micro-leaks at joints hidden behind walls or under floors. These leaks are slow enough that you do not see obvious water damage, but they steadily drain system pressure. We investigate both internal boiler components and the wider pipework system.

Yes, we work in Eton regularly. The conservation area restrictions mean external flue terminals on street-facing elevations are often not permitted. We design internal flue routes and condensate pipe solutions that comply with both Gas Safe requirements and the planning restrictions. This requires more planning upfront but ensures a compliant installation.

It depends on the extent of the water damage. If flood water reached the electrical controls, gas valve, or PCB, these components are typically compromised and replacement of the entire boiler is usually the safest option. If only the lower casing was affected and internal components remained dry, targeted repair may be viable. We assess the unit thoroughly before recommending either option, and when replacing, we always position the new boiler above the 2014 flood level.

Not necessarily. Large rooms with high ceilings, original sash windows, and uninsulated solid walls have very high heat loss. The boiler may be working perfectly but the system was simply undersized for the actual heat demand. We calculate the heat loss for your specific rooms and advise whether the boiler output is adequate or whether a higher-output unit (or additional radiators) is needed.

Yes, Dedworth is one of our busiest areas in Windsor. The 1950s-60s housing stock has typical mid-century heating challenges — aging copper systems, gravity-fed layouts, and old steel radiators. We repair and upgrade these systems regularly and can advise on converting to modern sealed systems when the time is right.

We plan pipe routes carefully to use existing voids — chimney breasts, floor joist spaces, and existing service routes — wherever possible. When new routes are needed through solid walls, we use core drilling rather than chiselling to minimise damage to the masonry. For lime-plastered walls, we avoid chasing and instead use surface-mounted boxing or route through adjacent rooms where the finish is less sensitive.

Standard component repairs — fans, diverter valves, PCBs — are priced similarly to any other location, typically £120 to £350. Where the cost can increase is when heritage constraints require internal flue rerouting, careful pipe routing through solid walls, or planning applications for external alterations.
