CCTV Surveys

A camera survey is used in a variety of different situations and the main reason may be if a new appliance needs to be connected to the existing chimney. The camera will make sure that the chimney is in good working order before work takes place.


If you're not sure about your chimney,

we can come and give it a check for you.


We will help by checking the flue lining

or chimney from the inside for any damage,

cracks or leaks and will advice you to

repaire or replace it, or could advice

you to fit a new stove with a liner already installed


We will check no blockages exist, that no tar build-ups have occurred, and that no dangerous gases are leaking from your flue. We use CCTV cameras for inspecting the inside of your chimney, and power sweeping equipment to make sure the sweep is done efficiently.



There is a personal answer machine if we are unavaible Please leave a message and contact phone number


You will be given an approximate time of visit ie 8am-10am, 9am-12pm, 2pm-5pm etc. Please be patient with time keeping, previous jobs and traffic can easily delay the estimated time of arrival but normally we try our best to be on time. 

The Visit

Please move items from the mantel piece and hearth, remove any un-burnt fuel on the fire.

We lay a heavy duty sheet in front of the fireplace and specially manufactured sweeps soot cloths to shield the fireplace and retain the soot behind.


Feel free to ask questions relating to your fire or chimney, stack and pot/terminal.

Any light furnishings or anything of particular value in the room we recommend is removed or covered.


On wet days or where there are light carpets we ask that the customers lay a trail of old sheets or newspaper from door to the fireplace for the sweep to walk on. We do pride ourselves in taking great care and respect of your home.


A chimney stack, pot and any cowls should be able to withstand a chimney sweeping, if for any reason a pot / cowl breaks or becomes dislodged during this process the sweep cannot take any responsibility.

However, in the unlikely event of an accident we will endevour to replace and repair at a reduced charge to the home owner.


When you have booked a chimney sweeping appointment, been allocated the time and we have driven to your property, If no work can be undertaken we will be entitled to charge a fee to cover time and fuel.




Chimney fires can quickly spread to your home or business place, putting property, livelihoods, and loved ones in danger. House fires often cause serious damage to the masonry and brickwork, leaving you with an expensive repair bill.


All chimneys need to be swept at least once a year, although if the chimney is used often we recommend twice a year. If you use solid fuel burning appliance you should have your chimney swept at least once a year, preferably before each winter as birds often use chimneys as nesting spots.

Falling stonework, rubble, spider webs and leafs can block chimneys and stop or reduce the flow of air. These all combined block previously working chimneys; any blockage can alter the combustion balance or cause carbon monoxide to enter the home instead of being safely vented from the property.


Carbon Monoxide

is a silent killer: it is colourless, tasteless and does not smell. Even low levels of Carbon Monoxide can lead to permanent ill-health or death, especially in children. The early symptoms of Carbon Monoxide poisoning can easily be mistaken for 'flu. They include nausea, headaches, tiredness, dizziness and pains in the stomach or chest. Look out for sooting or staining around your appliance: it is a sign of inadequate venting of gases.


It is vital that appliances are properly installed as well as serviced, and are sufficiently ventilated. We also strongly recommend the installation of a carbon monoxide detector in your home, which is also required under Building regulations for new installations.

What to do

If your appliance begins to burn slowly, goes out frequently or if you smell or suspect fumes:

Open doors and windows.

Carefully put out the fire, or allow it to burn itself out.

Do not stay in the room any longer than necessary.

Do not attempt to re-light the appliance until a professional has checked it.


Never leave an open fire without a fireguard in place, and if there are children in the home, the fireguard must be securely fitted to avoid accidents
