Parquet Floor Restoration in London
Structural Rescue for Damaged and Historic Floors
Parquet restoration is far more than sanding. When blocks are loose, lifting, missing, or hidden beneath carpet, proper restoration involves structural repairs before refinishing can even begin.
We offer original old parquet floor restoration in London, rescuing historic floors including herringbone, chevron, basket weave, and period installations. Using over 30 years of specialist experience, we reclaim block sourcing, subfloor levelling, and expert finishing. Get your parquet floors restored today!
What Makes Parquet Floor Restoration Different From Sanding
Parquet restoration addresses the structural integrity of the floor itself, while sanding focuses purely on surface refinement. If your blocks are solidly fixed, sanding may be enough. However, if the adhesive has failed, sections are missing, or the subfloor is compromised, restoration becomes essential. The repair can be done by lifting unstable blocks, removing failed adhesives such as bitumen, repairing or levelling subfloors, sourcing matching replacements, and re-laying original patterns before sanding begins.
At Sanding Wood Floors, we assess every parquet floor individually to determine whether full restoration or straightforward sanding is required. Every client receives the correct service, avoiding unnecessary expense while properly preserving their floor.
| Aspect | Parquet Restoration | Parquet Sanding |
|---|---|---|
| When it applies | Loose, lifting, missing, or damaged blocks requiring structural repairs | Secure blocks with surface wear only |
| Bitumen involvement | Blocks are lifted and bitumen adhesive removed before re-laying | No bitumen removal required |
| Subfloor work | Often includes levelling and repairs after adhesive removal | Usually unnecessary |
| Replacement blocks | Matching reclaimed blocks may be required for missing sections | Not needed |
| Project timeline | Longer due to repair, levelling, and curing stages | Standard sanding timeframe |
| Cost | Higher because of additional labour and materials | Lower standard sanding cost |
| Outcome | Full structural restoration plus refinishing | Surface refinishing only |

The Challenges of Old Parquet Restoration
What We Find Under the Carpet
Older parquet floors naturally hide serious structural issues beneath their surface, especially in period London homes where coverings have concealed original flooring for decades. Beneath carpets, tiles, or vinyl, we commonly uncover failed adhesives, missing blocks, uneven subfloors, and extensive movement that require specialist restoration before sanding can safely begin.
Bitumen-Laid Floors
Parquet floors installed between the 1930s and 1970s were typically fixed with hot bitumen adhesive, a black tar substance that becomes brittle with age. As adhesion fails, blocks loosen and lift.
Restoration requires careful block removal, specialist bitumen scraping from both blocks and subfloors, and re-laying using Bona R850 adhesive, which reacts effectively with residual bitumen.
This chemical compatibility is why R850 is the professional standard for bitumen-laid parquet re-laying, not all modern adhesives will bond reliably over even trace bitumen residue.
Missing and Damaged Blocks
Heating installations, plumbing works, or room alterations frequently cause missing blocks. Matching replacements requires reclaimed timber with the same species, age, and imperial dimensions as the original floor.
We source period-appropriate salvage blocks across the UK or carefully reuse hidden sections from within the property itself, particularly for herringbone floor restoration in London and heritage properties.
Where block gaps are too small to fill with replacement blocks but still require filling, resin gap filling is integrated into the sanding stage. For full detail on the trowel-fill method used for parquet, see our gap filling with resin service →
Subfloor Damage and Levelling After Bitumen Removal
Removing old bitumen often damages concrete subfloors, leaving pitted, uneven surfaces unsuitable for reinstallation. We assess this during the survey and apply acrylic levelling compound to restore flatness within ±2mm per 1.8m, the professional tolerance required for a flat sanded finish.
The levelling compound is applied in coats of no more than 3mm at a time and requires 24 hours drying before block re-laying begins. Proper levelling at this stage prevents the boards from rocking, creaking and producing an uneven sanded surface.
Floors Discovered Under Carpet, Tiles or Other Coverings
Floors hidden for decades can often be beautifully restored, but they are rarely straightforward. Adhesive residues, movement from years of compression, missing sections, and concealed damage all influence the restoration scope.
For period homes, Victorian parquet restoration preserves original craftsmanship while remaining significantly more cost-effective than full replacement, restoration typically costs £30–£55/m² versus £80–£120/m² for a new herringbone installation.
Our Parquet Floor Restoration Process
From Structural Repair to Finished Floor
Successful parquet restoration requires far more than sanding alone. Each stage must be completed in the correct sequence, structural assessment and adhesive removal through precision re-laying, specialist sanding, and finishing – ensuring the restored floor is stable, level, and built to last.
Step 1: Free Survey and Assessment
Written quotations separate structural restoration costs from sanding and finishing costs. Clients see exactly what each stage costs before committing. Quote within 48 hours of survey.
Step 2: Block Lifting and Bitumen Removal
Loose and unstable blocks are carefully lifted, removing one block can loosen up to 10 adjacent blocks due to the interlocking tongue-and-groove structure, so this stage is methodical, not rushed.
Old bitumen is removed from block backs and subfloors using specialist scarifying equipment. All salvageable blocks are stored and sorted – broken or unmatchable blocks are set aside for replacement sourcing at Step 3.
Step 3: Block Sourcing and Subfloor Levelling
Acrylic levelling compound creates a stable, flat base within ±2mm per 1.8m. Drying time: 24 hours before block re-laying can begin.
Step 4: Block Re-Laying
Replacement blocks are integrated seamlessly. All blocks must cure for 24–48 hours before sanding begins.
Step 5: Sanding (Multi-Directional)
Parquet requires specialist sanding because the grain runs in multiple directions simultaneously, a belt or drum sander used in one direction will leave visible sanding marks across blocks running perpendicular.
We use the Lagler Trio multi-disc machine for the main floor area, three rotating discs sand evenly across all grain directions and the Lagler Flip for perimeter edges. Grit sequence: 24→40→60→80.
Gap filling with sanding dust and resin between passes. For full detail on the parquet sanding stage see our parquet floor sanding service →
Step 6: Finishing
We apply protective finishes (lacquer, oil, or hardwax oil) depending on usage and style preferences. Natural oils particularly suit herringbone in period homes, enhancing the grain character of old-growth timber.
Staining is available where colour enrichment is desired before the finish coat is applied. For a full comparison of finish types and long-term performance, see our wood floor finishing guide →
Parquet Floor Restoration Cost in London
Parquet restoration costs vary significantly based on the structural condition of the floor. Where blocks are stable and only bitumen adhesive has failed, costs are lower.
Where large sections are missing, subfloor damage is extensive, or rare species blocks need sourcing, costs rise considerably. The pricing below covers the restoration elements – sanding and finishing is quoted separately.
Bitumen removal (block backs + subfloor)
Block re-laying (Bona R850)
Reclaimed block sourcing + fitting
Subfloor levelling
Sanding + 3 coats lacquer (post-restoration)
Full restoration + sanding + finishing
Actual restoration pricing can only be confirmed during the survey, as concealed issues such as failed bitumen, subfloor damage, moisture problems, or missing sections significantly affect labour and material requirements. Every floor is assessed individually to provide an accurate written quotation.

Frequently Asked Questions
Can an old parquet floor hidden under carpet be restored?
The key factors are block integrity (is the timber still solid?), extent of missing sections, and subfloor condition. Restoration typically costs £30–£55/m², significantly less than replacing with new herringbone parquet at £80–£120/m².
We lift a corner and assess block condition before quoting, no commitment required at the survey stage.
What is bitumen, and why does it need to be removed?
It must be removed from both block backs and the concrete subfloor before re-laying, because even trace residue significantly extends the cure time of modern adhesives from 6–8 hours to over 24 hours and can weaken the long-term bond.
Bona R850 is specified for parquet re-laying over residual bitumen because it is chemically compatible with it, unlike most general-purpose wood adhesives.
How do you source matching parquet blocks for missing sections?
Historic parquet was produced in imperial sizes (9″×3″ and 7″×2¼” are the most common), which are not reproduced in modern metric production. Where salvage networks cannot provide an exact match, we use blocks from hidden areas of the same floor (under fitted cupboards, behind skirtings) and fill those exposed positions with the best available salvage match.
We never use modern metric blocks on an imperial-sized floor, the dimensional difference is visible even after sanding and sealing.
How long does a full parquet floor restoration take?
Heavily damaged floors or those requiring extensive block sourcing take longer up to 2 weeks for larger rooms with significant missing sections. We confirm the timeline in writing at the survey.
Is it worth restoring a parquet floor vs installing a new one?
The honest exception: where more than 40% of blocks are beyond repair, patching becomes impractical and replacement costs begin to converge with restoration costs. We assess this honestly at the survey and give a clear recommendation before any work begins.
