CICO Chimney Lining System

We offer the best way of banishing your CHIMNEY PROBLEMS

Fire is not drawing properly

This is usually the result of a cold or an obstructed flue or it can arise from insufficient height relative to the ridge of the roof or an adjacent building. Large unnecessary voids at the base of the chimney may also stop the fire drawing properly. Sometimes double glazing and very efficient draught excluders around doors, etc, may prevent an adequate flow of air for the fire to work correctly.

Falling bricks or Mortar in the fireplace

Bits of brick or mortar falling down the flue indicate a serious deterioration in the chimney structure. Such deterioration normally occurs from the inside of the flue but if there is any indication of weakness on the outside of the chimney then attention is obviously necessary.

There are fumes in the room

These may not be easily detected on closed appliances although if, with an open fire, the chimney smokes back into the room they are then obvious. Fumes contain carbon monoxide and are dangerous. Where there are leaks in the chimney the fumes can find their way into upstairs rooms and attics. Sometimes a tell-tale smoke stain around the edge of a carpet shows the presence of fumes.

The fire or stove is using too much fuel

Large uninsulated flues require a lot of heat and fuel to make them draw. In particular high efficiency modern appliances have only a relatively small outlet pipe for the fumes. If these discharge into a much larger uninsulated flue, their rise can be decelerated to the point when the appliance just will not draw. An insulated flue of the correct size is required to ensure that an adequate draught is created for them to burn as their designers intended. Otherwise they will use too much fuel and the slow moving fumes will also condense into acids which will attack the internal surface of the chimney.

Fire risk?

Tar and soot deposits are a considerable fire risk, combine this with poor chimney structure or floor joists built up into thestack and the whole house is at risk.

The fire creates excessive soot

This usually means a lazy and inefficient flue although some bituminous coals are particularly prone to this. Such a flue may not be the right diameter for the fire or stove, or may not be satisfactorily insulated so that the fumes do not rise fast enough and therefore create soot deposits. Excessive soot and tar can be a considerable fire hazard, particularly if the chimney structure has deteriorated; or where, on 19th century property for example, floor joists have been built into the stack, when the whole house can be at risk.

The chimney breast feels hot

This means that the chimney has deteriorated and may be dangerous. A hot wall in the room above may be a similar symptom. If stains also appear on the chimney breast this is a sign that tar or acids have condensed and are eating into the chimney mortar and brickwork.


It is a requirement that all chimney lining work be carried out using tested and approved materials, installed to an approved code of practice. The CICO Chimney Lining System has been rigorously tested to meet these requirements and awarded the designation T600 N2 S D3, the highest for this type of lining. Installation can only be carried out by trained and accredited installers.

  1. CICO undertake a survey of your chimney without obligation and provide a written quotation.

  2. The chimney is cleaned and openings made at bends.

  3. A toughened rubber former is passed down the flue, inflated and correctly positioned using the openings. The inflated size of the former is adjusted to suit the heating appliance or fireplace.

  4. All openings and the bottom of the of the flue are sealed and special CICOMIX refractory cement is pumped into the chimney completely filling the space around the rubber former. Every crack, joint and void is permanently sealed.

  5. When the CICOMIX has hardened the rubber former is deflated and removed, leaving an efficient, smooth, insulated flue.

  6. The hardened CICO lining seals then walls of the flue preventing smoke or fumes leaking into the rooms. Down draughts are reduced by the warm insulating properties of the CICO lining.

  7. The correctly sized flue will allow the heating appliance or fire to work at maximum efficiency, reducing the build up of soot and tar deposits and using less fuel.

The CICO Lining provides a total solution to all your chimney problems.

The CICO Lining has substantially added to your internal chimney structure, making it safe by sealing all gaps and cracks.

The CICO Lining has created a highly efficient, joint free, permanent flue.

New Buildings

Well proven as a re-lining system, the CICO Chimney Lining System is gaining acceptance in the new-build sector where its efficient, joint free, insulating properties give it a distinct advantage over traditional flue methods. The developer simply builds an empty chimney shell, leaving CICO to do the rest.

Imagine the inside of a chimney stack permanently rendered throughout with a thick insulating coating to provide a highly efficient flue, cure erosion and prevent smoke leakage. The well established CICO Chimney Lining System does all this for both existing and new properties. Fully tested and approved to designation T600 N2 S D3, this system can only be installed by trained and accredited installers.

As well as specialising in the CICO system, we provide a full range of chimney, flue and fireplace services to Householders, Local Authorities, Insurance Companies and others.
