Period Fireplace Restoration for London Victorian Terraces: Cast Iron, Marble, and Tile Reinstatement

THE CAST IRON REGISTER GRATE — THE CENTRAL FUNCTIONAL ELEMENT OF THE VICTORIAN PERIOD FIREPLACE — IS THE COMBINATION FIRE BASKET, ASHPAN, AND REGISTER PLATE (THE CLOSING DEVICE FOR THE THROAT OF THE CHIMNEY) THAT SAT WITHIN THE FIREPLACE OPENING AND FORMED THE PRACTICAL HEART OF THE VICTORIAN ROOM HEATING SYSTEM.

PERIOD VICTORIAN REGISTER GRATE TYPES: COMBINATION HOBS GRATE (THE MOST COMMON GROUND FLOOR ROOM GRATE IN A LONDON VICTORIAN TERRACE — COMBINES THE FIRE BASKET WITH FLANKING IRON HOBS ON EACH SIDE — USED FOR COOKING AND HEATING IN THE KITCHEN/BACK ROOM, AND IN A SIMPLIFIED FORM FOR THE FRONT RECEPTION ROOM): CAST IRON, DECORATED PANELS (FIREBACK AND CHEEKS — TYPICALLY WITH FLORAL, ACANTHUS, OR SUNFLOWER MOTIFS — CHARACTERISTIC AESTHETIC STYLE DEPENDING ON THE DECADE: EARLY VICTORIAN 1840S-1860S: SIMPLER, MORE RESTRAINED ORNAMENT; LATE VICTORIAN AESTHETIC MOVEMENT 1870S-1890S: SUNFLOWER, LILY, JAPANESE AESTHETIC INFLUENCE — THE MOST RICHLY DECORATED AND MOST DESIRABLE PERIOD). BEDROOM GRATE (SMALLER — TYPICALLY 18-INCH OR 16-INCH OPENING — SIMPLE BASKET AND SURROUND — FOR BEDROOM FIREPLACES). REGISTER PLATE (THE PIVOTING DAMPER — SET IN THE THROAT OF THE CHIMNEY JUST ABOVE THE GRATE — CAST IRON PLATE WITH A HANDLE — OPENED TO ALLOW DRAW WHEN THE FIRE IS LIT, CLOSED TO SEAL THE FLUE WHEN NOT IN USE — PREVENTS DRAUGHTS AND HEAT LOSS WHEN THE FIRE IS NOT BURNING).

RESTORATION OF AN EXISTING OR SALVAGED CAST IRON REGISTER GRATE: RUST REMOVAL: WIRE BRUSH ALL CORRODED SURFACES — APPLY NAVAL JELLY (PHOSPHORIC ACID-BASED RUST CONVERTER — GRANVILLE BILT-HAMBER FERROSOL OR JENOLITE RUST REMOVER) TO CONVERT SURFACE RUST.

THE FIREPLACE SURROUND — THE DECORATIVE ARCHITECTURAL FRAME AROUND THE FIREPLACE OPENING — ON A LONDON VICTORIAN TERRACE WAS TYPICALLY MADE OF: CARRARA WHITE MARBLE (THE MOST COMMON MATERIAL FOR FRONT RECEPTION ROOM FIREPLACE SURROUNDS IN MID-TO-LATE VICTORIAN LONDON TERRACES — A PLAIN WHITE OR CREAM STATUARY MARBLE WITH FINE VEINING), SLATE (DARKER AND MORE COMMON IN LESSER ROOMS AND IN NORTH LONDON — BLACK SLATE SURROUNDS ARE VERY PERIOD-AUTHENTIC AND VISUALLY STRIKING), OR TIMBER (PAINTED SOFTWOOD — THE CHEAPEST OPTION — FOUND IN SECONDARY ROOMS AND IN TERRACES AT THE LOWER END OF THE MARKET).

MARBLE SURROUND CLEANING AND RESTORATION: SURFACE STAINING AND DISCOLOURATION: VICTORIAN MARBLE SURROUNDS ARE FREQUENTLY FOUND WITH: HEAVY SOOT AND CARBON DEPOSIT (FROM THE ORIGINAL USE AS A FIRE SURROUND — EVEN WHERE THE FIRE WAS BANKED RATHER THAN OPEN — SOOT PENETRATES AND STAINS THE SURFACE). PAINT (MANY ORIGINAL MARBLE SURROUNDS WERE PAINTED DURING THE 20TH CENTURY — TYPICALLY OVERPAINTING WITH GLOSS PAINT IN THE MISGUIDED BELIEF THAT THIS IMPROVED THEIR APPEARANCE OR EASE OF MAINTENANCE). CLEANING METHOD (PALLISTER MARBLE RESTORATION — LONDON — OR SPECIALIST MARBLE RESTORATION CONTRACTORS): METHYLENE CHLORIDE PAINT STRIPPER (WHERE PAINT IS PRESENT — APPLIED WITH POULTICE — LEFT 1-3 HOURS — CAREFULLY REMOVED WITH WOODEN AND PLASTIC TOOLS — NOT METAL WHICH SCRATCHES MARBLE).

MARBLE POLISHING COMPOUND (MARBLEX M502 OR EQUIVALENT): TO RESTORE POLISHED FINISH WHERE THE SURFACE HAS BECOME DULL.

REPRODUCTION MARBLE SURROUNDS (NEW — HAND-CARVED CARRARA MARBLE): CHESNEY'S (LONDON) OR WESTLAND LONDON (OLD KENT ROAD — WEST LONDON — SPECIALIST IN REPRODUCTION AND ANTIQUE ARCHITECTURAL FITTINGS).

THE HEARTH TILING OF A LONDON VICTORIAN TERRACE PERIOD FIREPLACE IS AS IMPORTANT TO THE AUTHENTICITY AND VISUAL IMPACT OF THE RESTORATION AS THE GRATE AND SURROUND — YET IS FREQUENTLY OVERLOOKED OR REPLACED WITH INAPPROPRIATE MODERN TILES.

VICTORIAN HEARTH TILE TYPES: ENCAUSTIC TILES (THE MOST DECORATIVE AND VALUABLE TYPE — GEOMETRIC OR FLORAL PATTERNS INLAID INTO THE CLAY BODY OF THE TILE — NOT A SURFACE PATTERN THAT CAN WEAR OFF — AVAILABLE IN NATURAL CLAY COLOURS: TERRACOTTA, BUFF, CREAM, AND BLUE-GREY): ORIGINAL MINTON ENCAUSTIC TILES: THE ORIGINAL TILES IN THE BEST LONDON VICTORIAN TERRACE PROPERTIES (MINTON — STOKE-ON-TRENT — MANUFACTURED THE MOST HIGHLY REGARDED VICTORIAN ENCAUSTIC TILES FROM THE 1840S ONWARDS — BASED ON MEDIEVAL TILE DESIGNS). ORIGINAL STYLE (EXETER — SPECIALIST SUPPLIER OF REPRODUCTION VICTORIAN ENCAUSTIC TILES — AVAILABLE IN MATCHING VICTORIAN DESIGNS): A LEADING UK SUPPLIER OF REPLACEMENT ENCAUSTIC TILES FOR VICTORIAN RESTORATION PROJECTS — THEIR RANGE INCLUDES DIRECT PATTERN REFERENCES TO THE ORIGINAL MINTON AND MAWS DESIGNS. PRICE: £80 TO £200/M² FOR REPRODUCTION VICTORIAN ENCAUSTIC TILES FROM ORIGINAL STYLE (DEPENDING ON PATTERN COMPLEXITY AND CLAY BODY).

PLAIN QUARRY TILES (FOR SECONDARY ROOMS AND BACK ROOMS): RED QUARRY TILES (150X150X12MM — FIRED TERRACOTTA — PLAIN — NO PATTERN): THE MOST COMMON HEARTH TILE IN SECONDARY ROOMS AND KITCHEN FIREPLACES OF LONDON VICTORIAN TERRACES. SOURCES: HARRIS HOOLE TILE (LONDON), ORIGINAL STYLE, AND H&E SMITH (STOKE-ON-TRENT).

INSTALLATION OF PERIOD HEARTH TILES: SUBSTRATE PREPARATION: THE HEARTH BASE (TYPICALLY REINFORCED CONCRETE OR NATURAL STONE HEARTH SLAB — SUPPORTED ON TRIMMER JOISTS SPANNING BETWEEN THE CHIMNEY BREAST AND THE ADJACENT FLOOR STRUCTURE): MUST BE FLAT (MAXIMUM 3MM DEVIATION UNDER A 2M STRAIGHT EDGE — PER BS 5385), CLEAN, SOUND, AND DRY BEFORE TILING. ADHESIVE (FOR PERIOD ENCAUSTIC TILES): BAL STRONGBOND RAPID (C2FTE — RAPID-SETTING FLEXIBLE TILE ADHESIVE — GREY) OR MAPEI GRANIRAPID (ALSO C2 GRADE — APPROPRIATE FOR NATURAL CLAY ENCAUSTIC TILES). GROUT (NATURAL HYDRAULIC LIME-BASED GROUT — FOR MAXIMUM COMPATIBILITY WITH PERIOD TILES — 3MM JOINT MINIMUM FOR ENCAUSTIC TILES — MAPEI ULTRACOLOR PLUS FA WARM GREY 111 — OR A LIME PASTE GROUT FOR THE MOST HISTORICALLY FAITHFUL RESULT).

WHERE A FIREPLACE OPENING HAS BEEN BLOCKED UP (THE MOST COMMON SITUATION IN LONDON VICTORIAN TERRACE PROPERTIES WHERE THE ORIGINAL FIRE WAS REMOVED IN THE MID-20TH CENTURY — THE OPENING WAS TYPICALLY BLOCKED WITH A SHEET OF HARDBOARD OR PLASTERBOARD, OR BRICKED IN WITH A HALF-BRICK OR LIGHTWEIGHT BLOCK PANEL), REOPENING THE FIREPLACE FOR PERIOD FEATURE REINSTATEMENT REQUIRES CAREFUL STRUCTURAL AND CONDITION ASSESSMENT.

OPENING UP A BLOCKED FIREPLACE ON A LONDON VICTORIAN TERRACE: STEP 1 — IDENTIFY THE EXTENT OF THE BLOCKING: KNOCK AND PROBE THE CHIMNEY BREAST FACE TO IDENTIFY THE BLOCKED SECTION (HOLLOW SOUND INDICATES PLASTERBOARD OR HARDBOARD BLOCKING — DENSE SOUND INDICATES BRICK INFILL). STEP 2 — OPEN UP AND ASSESS: CAREFULLY REMOVE THE BLOCKING PANEL OR BRICK INFILL. INSPECT THE INTERIOR OF THE FIREPLACE OPENING: CHECK FOR RETAINED ORIGINAL FEATURES (FIREPLACE BACK — ORIGINAL FIRE BRICK LINING — ORIGINAL REGISTER PLATE — ORIGINAL TILE CHEEKS — FREQUENTLY FOUND INTACT BEHIND A SIMPLE HARDBOARD OR PLASTERBOARD BLOCKING PANEL). INSPECT THE CHIMNEY FLUE ABOVE (BORESCOPE INSPECTION — AS FOR CHIMNEY SURVEY): CONFIRM THE FLUE IS CLEAR, NOT BLOCKED BY DEBRIS OR NESTING BIRDS, AND THAT THE LINER IS INTACT (CRITICAL BEFORE REINSTATING A WOOD-BURNING STOVE OR OPEN FIRE). STEP 3 — CHIMNEY SWEEP: HAVE THE FLUE SWEPT BY A NATIONAL ASSOCIATION OF CHIMNEY SWEEPS (NACS) MEMBER BEFORE ANY NEW FIRE IS LIT.

FLUE LINER SPECIFICATION (WHERE A WOOD-BURNING STOVE IS TO BE INSTALLED RATHER THAN AN OPEN FIRE): A STAINLESS STEEL FLEXIBLE FLUE LINER (316 GRADE STAINLESS STEEL — TO BS EN 1856-1 — 150MM DIAMETER FOR MOST WOOD-BURNING STOVES) MUST BE INSTALLED WITHIN THE EXISTING BRICK CHIMNEY FLUE BEFORE A WOOD-BURNING STOVE IS COMMISSIONED — THIS IS A LEGAL REQUIREMENT FOR GAS AND SOLID FUEL APPLIANCES UNDER BUILDING REGULATIONS APPROVED DOCUMENT J (COMBUSTION APPLIANCES AND FUEL STORAGE SYSTEMS) AND IS REQUIRED BY HETAS (HEATING EQUIPMENT TESTING AND APPROVAL SCHEME — THE STATUTORY BODY FOR SOLID FUEL HEATING IN THE UK): HETAS REGISTERED INSTALLER REQUIRED FOR THE WOOD-BURNING STOVE AND LINER INSTALLATION.

PERIOD FIREPLACE RESTORATION AND REINSTATEMENT IN A LONDON VICTORIAN TERRACE IS PRIMARILY AN INTERNAL WORKS MATTER AND DOES NOT IN ITSELF REQUIRE PLANNING PERMISSION UNDER THE TCPA 1990 (PLANNING PERMISSION IS REQUIRED FOR CHANGES TO EXTERNAL APPEARANCE — NOT INTERNAL ALTERATIONS IN A NON-LISTED BUILDING).
