Fireplace Installation & Re-modelling

From small changes to compete remodelling, Incendium’s second most popular service is remodelling the fireplaces that we fit our wonderful wood burning or multi fuel stoves into. That being said, many of our fireplace remodels are appropriate to use for an open fire, once they have passed the appropriate checks.

Whether the alterations to your fireplace are simply to make it safe for the installation of a solid fuel stove, or to completely update the look of your fireplace so it is more in keeping with the rest of your home, Incendium’s teams have years of experience with all the skills required to undertake every aspect of the work to the highest of standards, giving your fireplace a facelift that will elevate the look and feel of your home.

Our standard alterations include opening up the fireplace to its original sized chamber, installing a new lintel, installing a riven slate hearth, fire boarding inside the opening and then patching in the plaster around the opening so that all that’s left to do is decorate. Although these are our standard alterations, we love to get involved with bespoke changes, from building brick pillars and installing lovely oak beams to fitting the most regal of stone surrounds. We can even build false chimney breasts around our twinwall flue installations. You can take a look at some more of the fireplaces we have transformed in our portfolio page.

Opening up the fireplace

Your fireplace will have an original builders opening that has normally been reduced in size throughout the years. We will open this back up to its original size and install a new lintel so that everything is structurally sound.


We supply and fit a riven slate hearth or a terracotta pamment hearth as standard, however we are also able to have one of the many appropriate materials cut to size once the fireplace has been opened up. We are also more than happy for you to supply your own material for the hearth if preferred, that in most cases can be cut on site. Other popular hearth options include; granite, brick, marble, tiles or even glass.


Our most popular option for inside the chamber is the fitting of a A1 rated fire board. Unlike others that use a cheaper cement board which leaves a lot to be desired, Incendium uses glasroc fire board which is smooth to the touch and leaves a lovely clean modern finish, which can also be painted if needed. Our second most popular option is to acid clean and repoint the original brickwork inside the chamber. In some instances we find that the brickwork can be too far gone to be saved, but more often then not, our skilled installers can replace any broken bricks providing an appropriate brick match can be found. We are also able to supply ready made brick or tiled boards that are fitted much in the same way as our fire board. Please view our products page for more information.


The final stage of the remodelling process is to patch in the plaster around the opening into the existing wall or we are able to plaster the entire chimney breast or wall if required. If expert HETAS installers, brick layers and tilers weren’t enough, Incendium also has experienced plasterers so that everything is finished to the highest of standards.

Opening up the fireplace means taking the size of the fireplace opening back to its original size when it was first built.

Because stoves work buy radiative and/or convective heat, the air space around the stove is really important in regards to not only the efficiency of the stove but also the build-up of heat. The size of your fireplace will ultimately dictate what size stove you can have but fortunately nowadays there are many a different shape and sizes to suit everyone’s needs.

The hearth, pronounced ‘half’, is the base of the fireplace that the stove, fire basket or cast iron & surround sits on.
