Level Your Floor Before New Flooring — Bromley Central (BR1)
Almost every problem with a new floor traces back to the subfloor. In Bromley Central we spend more time on preparation than on the finish flooring itself — because a wood floor over a 6mm hollow is a wood floor that will squeak, cup and eventually fail. Getting the base flat, dry and secure is 70% of the job.
From £420 · Level survey £180 (refunded against booked work). Latex from £14/m², ply overlay from £22/m².
Typical turnaround: 1–3 days including cure time; larger areas 3–5 days.
Our repair process in Bromley Central
Step 1
Level survey
Straight-edge and laser survey across the whole area. We map high and low points, moisture-test the sub-deck, and give you a written spec of what needs doing.
Step 2
Fix loose or damaged sub-deck
Re-screw perimeter, replace damaged boards, packer under joists where levelling is required. Structural first, cosmetic second.
Step 3
Apply DPM if needed
For concrete without a moisture barrier we apply a two-coat epoxy DPM (Bona R540 + R580) or a bituminous membrane, depending on moisture readings.
Step 4
Latex self-levelling compound
Feather in dips with fibre-reinforced latex compound; pour a proper self-levelling layer where the deviation is large. Cures in 24 hours to a flooring-ready surface.
Step 5
Ply overlay where needed
For older sub-decks or where levelling depth would be excessive, we overlay with 5.5mm ply screwed at 150mm centres — the flooring industry standard for a stable base.

Subfloor Levelling in Bromley Central — common questions
- Can I DIY the levelling?
- For small feathering, sometimes yes. For anything over 5mm depth or requiring DPM or overlay, we'd recommend against it — the compound and prep skills matter, and re-doing it is more expensive than doing it right first time.
- Can I lay engineered wood on an uneven concrete floor?
- Only with proper preparation. Modern click-together engineered systems need 3mm/2m or better. Beyond that, the click joints stress, then fail. Latex first, floor after — no shortcut.
- Can you level over a chipboard sub-deck?
- Yes — but we usually re-screw the deck first (perimeter and joist centres), and if it's badly out of level we overlay with ply. Feathering latex directly onto chipboard rarely holds long-term.
- Do you cover Bromley Central for subfloor levelling?
- Yes — Bromley Central (BR1) is on our regular Bromley route. We do subfloor prep for our own flooring installs and also for other flooring contractors in the area.
- How much does subfloor levelling cost in Bromley Central?
- Latex self-levelling is typically £14–£22/m² depending on depth. Ply overlay is £22–£30/m². For a typical open-plan BR1 kitchen-diner, £600–£1,600.
- What about underfloor heating — does that change the prep?
- Yes — wet-lay UFH screed needs full commissioning cycle (typically 21 days) before we'll lay flooring. Electric mat UFH usually goes over a latex layer we install first. Different approach for each system.
