Side-Return & Wrap Engineered Wood Flooring in Croxley Green
In Croxley Green (WD3) 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 1930s semi extension floor has a 5–8mm step at the join — always visible, always regretted.
Level, thickness and step control on Croxley Green extension floors
The new screed in a Croxley Green 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 Croxley Green
For 1930s semi Croxley Green 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.

Getting the heating right in a new Croxley Green extension floor
Glue-down to screed on 1930s semi Croxley Green extensions gives the best heat response and eliminates drum-resonance on a hollow-sounding floor. On Croxley Green extensions we glue-down 85%+ of UFH installs.
Kitchen Extensions in Croxley Green — questions
- Can I blend a new extension floor into my existing Croxley Green 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 Croxley Green?
- In Croxley Green 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 Croxley Green 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 Croxley Green extensions.
- What warranty covers a Croxley Green kitchen extension floor?
- 10-year workmanship + manufacturer wear warranty (20-year residential typical). We retain UFH commissioning records for manufacturer warranty compliance on every Croxley Green extension.
- How long after the extension is finished can I fit the floor in Croxley Green?
- New screed needs 1 week per centimetre to dry — a 75mm slab needs 7–10 weeks before flooring is safe. Dehumidification can accelerate; guessing cannot. We CM-test on every Croxley Green extension fit.
- How long does a full Croxley Green kitchen extension floor take to fit?
- 5–7 working days for a typical Croxley Green rear extension (18–25m²) plus retained kitchen, including UFH commissioning, subfloor levelling and silicone perimeter.
