Original Floorboard Gap Repair — Writtle Specialists
In period conservation cottage homes in CM1, original pine boards are one of the most valuable features. Rip-and-replace destroys character and doesn't return the investment. Gap-fill and refinish, done properly, transforms the room without touching the character.
From £560 · Includes survey, fill, sand and finish. Free draught assessment on the same visit.
Typical turnaround: 3–5 days for a typical room; larger houses in stages by room.
What's actually happening
The likely root causes in Writtle's conservation cottage homes and along A414 / A12:
- 1
Historic lift-and-refit that never gapped correctly on relay
- 2
Woodworm damage in older joists causing board drop and gap widening
- 3
Central heating driving seasonal moisture cycles the wood wasn't designed for
- 4
Sub-floor ventilation drawing air up through the gaps (badly on some listed properties)
- 5
Original boards laid at high ambient RH, now dried to 8–10%
What you're seeing in Writtle
Common signs we diagnose in CM1 gappy floorboard repair calls:
- Visible strips of dark from the joist below between every board
- Gaps wider in winter (dry air), narrower in summer — seasonal movement
- Cold rooms above unheated cellars or void spaces
- Grit and dust rising up between boards when you walk
- Uneven finish where filler from an earlier job has fallen out

Our repair process in Writtle
Step 1
Survey & gap measure
We measure gap widths at multiple points and check seasonal movement history. That tells us whether flexible fillet, resin fill or relay is the right answer.
Step 2
Choose the method
Under 3mm: sawdust-and-resin (period-correct look, hard finish). 3–8mm: flexible acrylic fillet (accommodates movement). Over 8mm or variable: pine slivers glued into every gap, then sanded flush.
Step 3
Fill & finish
Gaps sealed, boards sanded flush, stain-matched to the original tone, and finished with the client's choice of oil, wax or lacquer.
Step 4
Draught-seal the perimeter
Skirting-to-floor gaps are often the biggest culprit for draught. We seal those separately with a decorator's caulk before the final finish.
Step 5
Aftercare
You get a maintenance schedule — including winter humidity targets — so the gaps don't reopen. That's the difference between a fill that lasts 8 years and one that lasts 18 months.

Gappy Floorboard Repair in Writtle — common questions
- How much does gap repair cost per m² in Writtle?
- For a full package — fill, sand, finish — in Writtle we're typically £45–£65/m² depending on gap severity and finish choice. Well below the cost of ripping up and relaying.
- Do you cover Chelmsford and CM1 for this work?
- Regularly — Writtle is on our Chelmsford route, about 3 miles from the centre. Free draught survey during the quote visit.
- How long will the gap fill last in Writtle?
- Correctly-chosen and installed: 10+ years for flexible fillet, 15+ for pine slivers, 8+ for sawdust-resin. Wrong method: it can fail inside a year. Method choice matters more than product.
- Do you do the sanding and refinishing at the same time?
- Yes — filling, sanding and finishing are one visit. Doing them separately means we'd be sanding twice, which shortens the life of the boards. One clean process, one team.
- Are there gaps you'd recommend not filling?
- Yes — some listed and heritage floors need sub-floor ventilation and the gaps are functional. We check building consents first and only fill where it's safe to do so.
- Will the filler crack out with seasonal movement?
- That's the whole point of choosing the right method. Rigid sawdust-resin cracks if boards move seasonally. Flexible fillet doesn't. We measure movement first and pick accordingly.
