2 Best Chimney Sweeps in Hertford: Trusted Local Experts

Open fires should be swept once a year. Wood burners and multi-fuel stoves need sweeping more often, usually 1 to 2 times a year depending on use and the type of wood burned. Range cookers and Agas typically need one sweep per year. Ask your sweep for a recommendation based on your heating appliance and usage.

A CCTV inspection sends a camera up your flue to show cracks, blockages, bird nests, or tar buildup on a screen. It costs £95 to £160 and is particularly useful if you have a problem chimney, are buying a house, or want to check an Aga or range cooker before bringing it back into use.

Yes, though timing matters. If birds are nesting, they are protected by law and cannot be disturbed. Once the birds have fledged (usually by late summer), a sweep can safely remove the nest for £85 to £170. Fitting a bird guard or cowl afterwards prevents it happening again.

If you have a wood burner, Aga, range cooker, or oil heating system, your buildings insurance often requires a valid sweeping certificate as proof of maintenance. A sweep will provide one after the job. Check your policy to be sure.

A power (rotary) sweep costs £95 to £160 and is used when tar or creosote has built up heavily inside the flue. This is common in chimneys that have burned wet wood or been neglected for years. Your sweep will advise whether a standard sweep or power sweep is needed.

A smoking chimney often points to a blockage, a flue that's too small for your appliance, poor ventilation in the room, or a leak in the flue itself. A sweep can check for blockages and perform a smoke or draw test (£40 to £75) to diagnose the problem. If the issue is structural, relining or repairs may be needed.
