Glasgow's architectural heritage brings unique heating installation requirements. We maintain complete upfront clarity on how tenement layouts and sandstone walls affect installation scope.
Internal recess kitchens often require vertical flue routing through attic voids or disused chimney stacks to discharge above the roofline.
Itemised in online quote from £150Glasgow blonde and red sandstone walls can exceed 600mm thickness, requiring diamond wet-core drilling equipment to preserve masonry.
Included in standard fixed quoteCondensing boilers produce mildly acidic wastewater that must connect internally to a soil stack or external insulated run to avoid winter freeze-ups.
