Renovating parquet: maintain, refresh or sand?
Not every scratch calls for a new floor, and not every renovation needs full sanding. The existing finish, condition of the wood and intended result determine the work. A useful quotation therefore describes more than a square-metre rate.
Which treatment suits the floor’s condition?
Start with the problem: dull traffic areas, deep scratches, dark patches or loose blocks. The contractor determines the method after inspecting the floor. Persistent moisture also calls for investigation of its cause.
| Starting condition | Useful assessment |
|---|---|
| Dull or dirty surface | Cleaning and appropriate maintenance or refreshing |
| Extensive marks in the wood | Suitability for sanding and a new finish |
| Individual damaged elements | Local repair or matching replacement pieces |
| Loose or swollen areas | Bond, substrate and source of moisture |
| A different colour is wanted | Trial area and possibilities of the existing timber |
Can every parquet floor be sanded?
Sanding removes wood. The remaining wear layer matters, not simply the original total board thickness. Previous refinishing and uneven areas affect the allowance. Have the actual floor assessed.
Solid parquet, engineered parquet and thin veneer flooring have different limits. Wood-effect laminate is not parquet and cannot be sanded back in the same way. If construction or previous treatments are unknown, say so in the enquiry.
Brushed textures, bevels and special factory finishes can change during renovation. Agree which features should be retained and what appearance is realistically achievable before work begins.
Address individual damaged areas
A deep defect does not necessarily have to be removed by sanding the entire floor. Replacing individual elements may be an alternative. Spare pieces or the original product reference help. Local repairs can leave differences in colour, sheen or texture.
Mention loose areas, significant distortion and water damage explicitly. A fresh coating does not solve a bonding problem. Intrusive work on older adhesives or substrates may first require material and hazardous-substance checks. Dark adhesive colour alone is not a reliable diagnosis.
Oil or lacquer?
The finish should suit use and intended upkeep. Oiled and lacquered floors require different care. Discuss not only sheen but also room traffic and the maintenance you are willing to carry out.
Refreshing without a full wood sand requires compatibility with the existing treatment. Residues of previous maintenance products can interfere with adhesion. Changing finish or colour is therefore more than swapping a cleaning product. For colour decisions, a trial on your own floor is more useful than a screen image.
Describe the areas requiring work
List affected rooms separately. A living room measuring 4.8 × 4 metres is 19.2 m²; a corridor measuring 1.2 × 5 metres adds 6 m², making 25.2 m² in total. Identify fitted furniture and any areas excluded from the work.
For an individual defect, describe its location and approximate size. The repair area may differ from the total area needing treatment for a consistent appearance. Mention stairs, thresholds and skirting separately: a flat floor-area rate does not automatically cover them.
How much does parquet refinishing cost?
One Basel-region contractor lists CHF 40–60 per m² for sanding with oiling or lacquering. VAT and travel are not clearly specified. This is an individual example, not a Swiss average.
Deep cleaning is not directly comparable with a full renovation. Small rooms, numerous edges, repairs and colour changes can influence the calculation more than area alone. Compare final amounts for the same scope.
- Treatment. Specify sanding, edges, necessary repairs and the finish.
- Associated work. Allocate furniture moving, skirting, protection, cleaning and disposal.
- Materials and charges. Check finishing products, travel, minimum charges and VAT.
- Unforeseen work. Approve additional replacement or substrate repairs separately.
Plan access and downtime
- Assess the floor. Agree scope, condition, existing treatment and possible repairs.
- Clear the work area. Decide who moves furniture and whether skirting needs removing. Coordinate access and other renovation work.
- Plan dust control. Discuss extraction and protection of adjoining areas. Good extraction does not replace an agreement on final cleaning.
- Allow drying time. Clarify walking, furniture, rugs and first damp cleaning separately. Timing depends on the chosen system.
Keep the result in good condition
At handover, request care instructions for the finish actually applied. Remove grit regularly, check suitable furniture pads and wipe up spills promptly. Use compatible cleaning products rather than changing treatments by guesswork.
Keep a record of products and treatment for later repairs. Recurring gaps, moisture or detachment call for assessment rather than more frequent oiling. Additional maintenance cannot correct every visible difference.
Frequently asked questions
Does every renovation require full sanding?
No. Depending on condition and the existing finish, cleaning and suitable refreshing may be enough. Deep defects or a change of finishing system need a different assessment.
How many times can parquet be sanded?
There is no fixed number for all floors. Remaining wear layer, construction, earlier work and condition determine suitability. Have the existing floor assessed.
Can just one damaged piece be repaired?
It may be possible depending on construction and finish. Matching replacement material helps. Clarify any visible differences and whether adjacent areas also need treatment.
When can furniture be put back?
Being able to walk on the floor does not mean it can take full loads. Ask separately about furniture, rugs and cleaning, based on the product and site conditions.
Do I need to know the wood species and wear-layer thickness?
No. Say if these are unknown. Area, visible condition and the intended result allow an initial assessment; the contractor checks technical suitability.
