Period Flooring in London Properties: Parquet, Encaustic Tiles, and Original Boards

Original flooring in a London period property is both an asset and a responsibility. Victorian encaustic tile hall floors, parquet herringbone in reception rooms, wide pine boards in upstairs bedrooms — these surfaces are irreplaceable in the truest sense. Once lifted and discarded, they cannot be put back. Replicas exist, but a floor laid in 1875 has a character that no new installation can reproduce: the slight unevenness of hand-laid tiles, the patina of a century of wear on timber, the particular colour of Victorian red quarry tile.

This guide covers the main types of original flooring found in London period properties, how to assess their condition, and what restoration involves.

Encaustic and geometric tile floors

The encaustic tile hall floor — a geometric pattern in terracotta, cream, black, and sometimes blue and red — is one of the defining features of the Victorian terraced house. From the 1860s onwards, manufacturers including Minton, Maw & Co., and Craven Dunnill produced tiles in standardised geometric patterns that were used in hundreds of thousands of London halls.

Assessment: Lift any carpet or floor covering carefully. Examine the tiles for cracking, lifting, and loss. Surface wear — where the pattern has worn away on the most-trafficked tiles — is normal and acceptable. Cracking can result from differential settlement, heavy impact, or poor bedding. Lifting results from failed bedding (often lime mortar that has carbonated and lost adhesion).

Restoration: Individual cracked or missing tiles can often be replaced from salvage — the standardised Victorian geometric range means matching tiles are findable. The Tile Association and architectural salvage dealers (LASSCO in London, Salvo) are the starting point. For widespread lifting, the floor must be relaid: carefully lift all tiles, clean the underside, and relay on a fresh sand-cement bed with appropriate adhesive.

Cleaning: Victorian tiles should never be cleaned with acid (which damages the surface) or steam (which may lift bonded tiles). A warm water wash with pH-neutral cleaner, careful scrubbing with a stiff brush, and a penetrating tile seal applied when dry is the correct approach. A professional stone and tile cleaner can transform a black, traffic-darkened Victorian hall floor back to its original character in a day.

What not to do: Do not lay new tiles over the originals to avoid the restoration cost. The height addition creates a threshold problem at the front door, and the originals — often in good condition — are permanently buried. Do not replace original geometric tiles with large-format porcelain or stone without serious consideration of the architectural loss involved.

Parquet floors

Hardwood parquet — typically oak, sometimes elm or teak — in herringbone, basket-weave, or brick-bond patterns was the premium floor finish for Victorian and Edwardian reception rooms. It is extraordinarily durable: a parquet floor in a well-maintained London property is routinely 100–140 years old and still serviceable.

Assessment: Check for lifting (panels loosening from the adhesive bed), cupping (edges raised higher than the centre — caused by moisture from below), and damage (gaps, missing blocks, surface scratches). Parquet laid on a concrete screed (common in ground-floor flats) is particularly vulnerable to moisture-driven lifting if the damp-proof membrane below is inadequate.

Sanding and refinishing: Original parquet can be sanded multiple times — each sand removes approximately 0.5mm of timber. A floor that has never been sanded has 2–4mm of timber above the tongue. Most original parquet can be sanded at least twice before the tongue is approached. A belt sander, edge sander, and detail sander are all needed for a complete parquet sand. The finish is then applied — hardwax oil for a natural, traditional result; water-based lacquer for a harder, more maintenance-free finish.

Replacing missing blocks: Original oak parquet blocks (typically 70 × 230 × 20mm, or 70 × 280 × 20mm) are available from salvage. New timber blocks can be stained to match but will sand out differently — the patina of a 100-year-old floor is not replicable. For large areas of loss, the question becomes whether to restore or replace the whole floor.

Relaying lifted sections: Individual lifted panels can be re-adhered with a compatible adhesive (Bona R848 or similar) if the blocks are undamaged. Widespread lifting requires full relaying — lift the whole floor section, clean the screed, address any moisture issues, then relay using modern parquet adhesive to current standards.

Wide pine floorboards

Original pine boards — typically 100–200mm wide, 25–32mm thick, and often 4–6m long — are found in the upper floors of most Victorian terraces. These are Scots pine (Pinus sylvestris) or Baltic redwood, grown slowly in northern forests and with a much tighter grain than modern plantation timber. They are dimensionally stable and take stain and finish well.

Assessment: Check for movement between boards (gaps caused by shrinkage over time — normal and acceptable), damaged boards, and extent of previous filling (many floors have been poorly filled with expanding wood filler that has since shrunk and fallen out).

Filling gaps: Gaps between original pine boards can be filled with thin timber slivers (slips of matching timber pushed into the gaps with PVA glue, then sanded flush) — the best result aesthetically and structurally. Alternative: natural caulk or coloured wood filler (for small, consistent gaps). Expanding foam or modern polyurethane fillers are not appropriate — they move differently from the timber and will work out of the gaps.

Sanding: Pine sands easily. Belt sand along the grain, edge sand around perimeters, and finish with a floor sander fitted with fine paper (60–80 grit final pass). Apply stain if required, then two or three coats of hardwax oil or water-based lacquer.

What to expect: An original pine board floor, even beautifully restored, will still have character marks — knots, minor colour variation, the ghost of old nail holes. This is appropriate and valuable. A uniform, characterless surface can be achieved with new flooring; an original floor's character is what makes it worth restoring.

ASAAN has restored original floors — parquet, encaustic tile, and pine boards — as part of whole-property renovation programmes across London. Our team coordinates specialist floor sanding contractors, tile restorers, and stone cleaners within the wider programme.
