Your floors are one of the most valuable features of your home, so handing them to the wrong contractor is an expensive mistake. Chelsea has plenty of original Victorian and Edwardian boards, parquet and herringbone, and period floors are harder to sand than modern ones. Poor work can leave machine marks, uneven edges, a patchy finish or boards sanded too thin to recover. This guide shows you what to check, which questions to ask, how to compare quotes and which warning signs to walk away from.
Why the Choice of Contractor Matters
A bad sanding job is rarely obvious on the day. The problems show up once the finish cures, or a year later when it wears unevenly. The most common issues are:
- Drum marks and swirl patterns from careless sanding
- Dust spread through the home because extraction was poor
- Uneven colour after staining without a test sample
- Over-sanded boards, especially on engineered and thin period timber
- Weak finish that scratches or peels within months
A reliable contractor prevents all of these, and a good one will also explain their choices so you understand what is happening in your home.
What to Check Before You Hire
Use this table as a checklist when you compare companies.
| What to check | Why it matters | What a good answer looks like |
|---|---|---|
| Public liability insurance | Protects you if something is damaged | They show a current certificate on request |
| Experience with your floor type | Parquet, engineered and period boards each need different handling | They explain how they approach your specific floor |
| Dust control | Fine dust spreads quickly and is a health concern | They describe their extraction equipment and how they contain the work |
| Written, itemised quote | Stops disputes over what was included | Area, sanding stages, finish, number of coats and extras are listed |
| Examples of recent work | Shows the quality you can expect | Photos of similar floors in your area |
| Reviews and references | Reveals how they behave when things go wrong | Recent, detailed feedback, not just star ratings |
| Trade body membership | Shows commitment to a code of conduct | They tell you which body and let you verify it |
Don’t be shy about verifying claims. A professional company expects the questions and will answer them readily.
How to Compare Quotes Properly
Price matters, but the cheapest quote is rarely the best value. Ask every company to quote for the same job, so you compare like with like. A good quote states:
- The area to be sanded, including stairs and hallways
- The finish (lacquer, oil or hard wax oil), its brand and the number of coats
- Whether edges, gap filling and repairs are included
- How dust is controlled
- How long the work takes and when you can use the floor again
For reference, sanding, buffing and finishing a wood floor in Chelsea now starts from around £25 per m², with extras such as gap filling and staining priced on top. Our guide to floor sanding costs in Chelsea breaks down typical prices by room size.
If one quote is far below the rest, ask why. The gap usually comes from fewer coats, cheaper materials, weaker dust control or a rushed process.
Red Flags to Avoid
| Warning sign | What it often means |
|---|---|
| No written quote | Nothing is agreed, so extras can appear later |
| Pressure to book today | They want a decision before you can compare |
| No insurance evidence | You carry the risk if something goes wrong |
| Vague about the process | They may lack experience or cut corners |
| No mention of dust control | Expect dust in every room |
| Unwilling to show past work | Little to show, or work that doesn’t impress |
| A price far below others | Thin finish, fewer coats or inexperience |
Check Reviews and Past Work
Reviews tell you how a company behaves when the job gets difficult. Look for comments on punctuality, cleanliness, communication and the finished result, not just the star rating. A mix of detailed positive reviews and calm responses to any criticism is a better sign than a wall of identical praise.
Photos matter just as much. Ask to see completed floors that match yours, whether that’s solid oak boards, parquet or engineered wood. You can see examples of our own jobs in the portfolio and read what customers say on our reviews page.
Questions to Ask Before You Book
These questions quickly show whether a contractor knows their craft:
- What is your experience with floors like mine? Period, parquet and engineered floors all behave differently.
- How will you control dust?
- Can you handle repairs, gap filling or staining if needed?
- Which finish do you recommend, and why? A good answer considers your lifestyle, not just the product.
- Can I see samples of the finish on my own floor? Colour and sheen look different on every timber.
- How long will the work take, and when can I walk on the floor?
- What happens if I’m not happy with the result?
Choosing a Company for a Period or Parquet Floor
If your home has original boards, take extra care. Old floors often have gaps, uneven boards, historic stains and thin timber that need judgement, not just a machine. Ask whether the company has handled similar properties, and whether the operator will assess each room individually.
For patterned floors, make sure the contractor understands the block layout. Our parquet floor sanding service is built around that kind of delicate work. We also offer engineered wood floor sanding, where thin wear layers need extra care and the sanding depth has to be judged board by board.
Frequently Asked Questions
How do I know if a floor sanding company is reliable?
Check insurance, ask for recent examples of similar work, read detailed reviews and get a written, itemised quote. A reliable company answers all of these openly.
Should I choose the cheapest quote?
Not automatically. Compare what each quote includes, such as coats of finish, dust control and repairs. A much lower price often means something has been left out.
How long does floor sanding take?
A typical room takes one to two days to sand, with extra time for the finish to dry between coats and cure. Ask for a clear timeline before work starts.
Can any company sand a period or parquet floor?
No. Old and patterned floors need experience, so ask for examples of similar jobs before you book.
Do I need to move out during sanding?
Not usually, but you will want to keep children and pets away from the working area and while the finish dries. A good contractor will explain how to plan around it.
Should I get more than one quote?
Yes. Two or three written quotes for the same specification make it easy to spot unusual prices and compare service.
