Repairs & Maintenance

 The pipe that comes out of the top of your stove is connected to a stainless steel flexible liner inside your chimney if it was installed properly, or to twin wall stainless steel pipes if you do not have a chimney. When you use your woodburner, the fire cement that seals this pipe, heats and cools and gets shaken about when the door opens and closes. After a while it needs replacing. If smoke is coming out of this seal into the room, stop using the fire immediately. Contact us to arrange a chimney sweep to fix your stove pipe seal or book a sweep online now

The inside of your stove is lined with vermiculite board, sometimes known as a stove liner. These are fireproof and help keep the heat in to keep the fire burning. Sometimes they crack and can be repaired with a small amount of fire cement to keep them burning for a while longer. A good chimney sweep can sell you fire cement, just ask when booking. If the bricks are too far gone, then you can order new ones from the stove manufacturer or have bespoke bricks made onsite. Contact us to arrange or to buy some fire cement.

The door on your stove has a busy life and occasionally can move around on its hinges or the handle can work its way loose. Usually a soft brush can get rid of any build up of soot or twigs that may be obsructing the bolts or hinges and WD40 is a great lubricant to help you tighten any handle mechanism. It may be that the door seal needs replacing. Watch out though the door is likely to be heavy and dirty. It's not usually an expensive repair but if too much air is getting into the stove then it will be burning fuel faster than necessary. Send us an email if you'd like us to fix it for you.

The glass in the door of your woodburner or multifuel stove is similar to the top of a electric ceramic hob. It is designed to withstand very high temperatures, and to have minimal expansion during heating and cooling. Unfortunately after a while it can crack or break. If this happens do not use your stove until it's fixed. New glass can sometimes be bought online, but sometimes has to be cut specially. Be careful when fitting it yourself, if it is too tight then this could create stress which may lead to cracking or breaking. Call us on 01462 431910 to get your ceramic glass repaired

The air sliders control how hot your stove is burning. Over time they can become clogged with soot, ash or twigs so give them a regular brush over. If they get too stiff to open, first check that they don't have a screw mechanism that just needs to be untightened before calling us or emailing gareth@chimneysweep.info

"A stove pipe thermometer helps prevent overburning your woodburner" - Heather (GTD)

After a while your woodburner will need a little bit of care and attention. Not keeping on top of things will mean that you won't get as much heat out of the fuel that you put into the fire and will spend more money than necessary on keeping warm. Please see below for help with these problems


The main problems that occur are

  1. Stove pipe cement cracking and falling out
  2. Brick liner panels cracking and dropping into the fire
  3. Door not closing properly, feeling loose
  4. Door glass cracked or fallen out
  5. Air controls are stiff and hard to open or close
  6. Smoke exiting into room through air controls (flue blocked)
  7. Not getting your chimney swept often enough

If your chimney or flue is blocked somehow, then the smoke won't be able to exit through the flue. The only place left to go is out through the air controls or the door seals. You should immediately close all the air controls to put the fire out. Do NOT open the door. Ventilate the room well until the smoke has cleared and then call a chimney sweep to take a look at the chimney. Call us on 01462 671555 to book a chimney sweep today.

Smoke Coming Into Room


For most people a regular annual sweep is enough, but if you are a regular user of your woodburner or multifuel stove it is recommended that you have your chimney or flue swept more often. Take a look at our FAQ page for details and visit our sister company's website to book your sweep in advance to avoid disappointment at busy times of the year.
