Side-Return & Wrap Herringbone & Parquet Flooring in Harold Wood
In Harold Wood (RM3) we typically survey a kitchen extension 8–10 weeks before the floor goes in. That gives the new screed time to cure, the UFH to commission, and us time to plan the level transition from the old kitchen subfloor into the new. Skip this planning and every new build extension floor has a 5–8mm step at the join — always visible, always regretted.
Level, thickness and step control on Harold Wood extension floors
The new screed in a Harold Wood kitchen extension is rarely at the exact height of the existing kitchen subfloor. On our surveys we measure both — target is under 3mm difference across the join. Above 3mm and we ramp with a matched threshold; above 8mm and we level with SLC before fit.
Blending new extension floors with existing kitchens in Harold Wood
For new build Harold Wood kitchens where the retained floor is Victorian solid pine and the extension is a new engineered oak, we design a deliberate transition — solid oak threshold band between old and new. Reads intentional, not retrofit.

Kitchen Extensions in Harold Wood — questions
- Can I have engineered wood in a Harold Wood extension over UFH?
- Yes — engineered wood is the ideal spec for Harold Wood extensions over UFH. Certified UFH-compatible ranges, glued down to screed, run at up to 27°C surface temperature. Solid wood cannot go here.
- Do we need to remove existing kitchen units on a Harold Wood extension floor job?
- Usually no — we fit up to the plinth line with colour-matched beading. Only jobs where the kitchen is being replaced anyway get full floor-under-cabinets install.
- Can I blend a new extension floor into my existing Harold Wood kitchen?
- Yes — but the winning strategy is to re-do both floors together, from one batch. Trying to match into an existing floor almost always shows the join. Costs more but reads seamless.
- Should the extension floor match the kitchen or the lounge in Harold Wood?
- In Harold Wood open-plan extensions the floor should match both — one continuous run through kitchen, dining and living. Zoning by flooring change is out of fashion and never re-sells well.
- Can the floor go in before the Harold Wood extension kitchen is fitted?
- Ideal sequencing: floor first, kitchen second. Puts the floor under the kitchen (better resale, better waterproofing) and avoids kitchen plinth transitions. We work this way on 70% of Harold Wood extensions.
- What warranty covers a Harold Wood kitchen extension floor?
- 10-year workmanship + manufacturer wear warranty (20-year residential typical). We retain UFH commissioning records for manufacturer warranty compliance on every Harold Wood extension.
