Side-Return & Wrap Luxury Vinyl Flooring (LVT & SPC) 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.

Getting the height transition right in Croxley Green rear extensions
Where the two levels genuinely can't be matched (rare, but real), we design a two-step visual transition with a matched threshold ramp — never a 'hope no-one notices' butt-join.
Making the extension read as one floor with the existing kitchen
On Croxley Green kitchen extensions we specify the whole floor — extension plus retained kitchen — as one order, from one batch. Trying to match into a 5-year-old kitchen board never works; the new boards read fresh, the old ones read weathered. Better answer: re-do both, so they're the same age from Day 1.

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.
