Before / After Gallery (Real School Floors)
Tired, scuffed, patchy halls brought back to a flat, clean, hard-wearing finish — ready for daily footfall, PE, assemblies and exams. Honest results, no filters, no clever angles.
Case Studies & Realistic Timelines (Built Around Holiday Works)
The question every facilities manager asks us first is the same: “How long will the hall be out of use, and exactly when can we let the children back in?”
After 31 years of doing this, here are the frameworks we plan around — honest, achievable, and tested on hundreds of UK school sites.
3-Day Holiday Turnaround
- Day 1: Floor protected, repairs carried out, full sand-down
- Day 2: Fine sanding plus first two coats of sealer
- Day 3: Final coat, inspection walk-round, sign-off with the site team
Best for: assembly halls that need a proper refresh inside a half-term break.
Full Sports Hall Upgrade + New Markings
- Heavy-duty commercial finish built for trainers and sports trolleys
- Court layouts confirmed in writing before any paint goes down
- Phased access planned around exams or summer school
Best for: PE halls, gyms and multi-use sports courts.
Phased Corridors & Multiple Zones
- Works phased so children always have a safe route through
- Loose, damaged or trip-hazard boards repaired or replaced
- Hard-wearing sealing system designed for daily school traffic
Best for: larger sites where shutting whole areas isn’t realistic.
Honest Pricing Guidance (So You Can Budget Early)
Every school hall is different — board type, condition, existing coatings and access all play a part — but these ranges give you a realistic starting point for budget conversations with your governors or trust. After a quick site visit, we always confirm a fixed-price quote in writing, with no surprise extras.

Guide pricing only — final cost depends on access, existing coatings, repairs required, drying conditions and cure times.
Sports Line Marking — Crisp, Durable, Properly Set Out
Once the floor is sanded and sealed, we set out and apply sports markings using a paint system that bonds properly with the seal coat — so the lines stay crisp through years of trainers, sports kit and gym trolleys. We’ll always confirm court dimensions and colour choices with you in writing before a single line goes down.
Markings We Apply
- Basketball (full and mini)
- Netball
- Badminton
- Volleyball
- Multi-court layouts in differentiated colours
What We Confirm Upfront
- Exact line layout and court placement
- Line width and colour scheme
- Sports-grade paint compatible with your finish
- Cure time and safe return-to-PE date

Frequently Asked Questions — School Floor Sanding
How long will the hall be out of use?
For most school halls, we’re in and out in 2 to 5 working days — including sanding, sealing, drying and the cure time before children can safely use the hall again. We’ll confirm exact access points and your safe-return date as part of the written plan, so you can publish PE timetables and assembly schedules with confidence.
Can you work during half-term, the summer holidays or weekends?
Yes — the bulk of our school work is scheduled around holidays, INSET days and weekends. We routinely run evening and weekend shifts when needed, and we’ll plan the programme backwards from your hard deadline (start of term, exam season, ParentPay nights, you name it) so the hall is open when you need it.
Is school floor sanding dusty or disruptive?
No — our 98% dust-free sanding systems capture the dust at source. We seal off the work zone, protect adjacent rooms, and hand the space back clean. As Matt Pears at Northgate Primary put it: “Great job by your crew.” That’s how we like every handover to go.
Do you carry out repairs and sports line marking too?
Yes — repairs are always assessed during the free site visit (loose boards, gaps, splits, water damage near radiators), and we include them in the fixed quote. Sports line marking is also a regular part of our school work, with the layout and colours confirmed by your PE department before we paint.
Are your technicians DBS-checked and fully insured?
Every Mr Sander® technician is fully trained, DBS-vetted and covered by comprehensive public liability insurance up to £5 million. We provide insurance certificates, RAMS and DBS documentation as part of the standard onboarding pack for school sites.
What finish do you recommend for a school sports hall?
For most school sports halls and assembly halls, we recommend a commercial-grade lacquer system — typically Bona Traffic HD or Junckers HP Commercial Lacquer. They’re built for high footfall, sports use, and easy daily maintenance. We’ll talk you through the exact spec based on how the hall is used and discuss slip-resistance requirements before quoting.
Do you offer a guarantee on school floor sanding?
Yes — every job comes with our written workmanship guarantee. If anything isn’t right with our work, we come back and put it right at no cost. That’s been our policy since 1994, and it’s a big part of why we have over 1,000 verified 5-star reviews averaging 4.8/5 from schools, businesses and homeowners alike.
Do you work UK-wide or just London?
We work UK-wide. Our operations base is at St Martins House, 1 Lyric Square, London W6 0NB, but we have crews regularly delivering school projects right across England, Scotland and Wales — from primary schools in the Home Counties to large secondary academies in the Midlands and North.
