Floors & Fix fits carpet throughout Harrow's HA1–HA3 postcodes, including Harrow-on-the-Hill, South Harrow, Kenton and Wealdstone. Edwardian semis in HA1 and HA2 need ply on the timber ground floor before carpet. Post-war council properties in Roxborough get moisture assessment as standard — we include any DPM preparation in the fixed price.
Harrow has a diverse housing stock centred on Edwardian semis in Harrow-on-the-Hill and South Harrow (HA1–HA2) with suspended timber ground floors, substantial 1930s semi-detached housing in Kenton and Wealdstone (HA3), post-war council housing in Roxborough with solid concrete, and newer apartment developments in HA1 and the Wembley area with underfloor heating.
66% of Harrow's housing stock predates 1970, with a significant proportion of Edwardian and 1930s construction carrying suspended timber ground floors across HA1–HA3. — ONS Census 2021, housing stock age, London Borough of Harrow
Harrow's housing stock requires different preparation by area. Edwardian semis in Harrow-on-the-Hill and South Harrow (HA1–HA2) have suspended timber ground floors that need 6mm structural ply before carpet is laid — without it pile creases across joist spans. The larger room proportions of these Edwardian properties suit a premium 80/20 wool-blend carpet. The 1930s semis in Kenton and Wealdstone (HA3) have suspended timber or mixed ground floors in good condition — ply preparation where needed. Roxborough's post-war council housing has solid concrete ground floors with elevated moisture; we always test and DPM where needed. HA1 and Wembley area new builds with wet UFH require a low-tog bonded-foam underlay.
The Edwardian semis in Harrow-on-the-Hill and South Harrow (HA1–HA2) have suspended timber ground floors in generally good condition — medium moisture risk given the elevated location. These larger Edwardian properties have generous room proportions and suit wider-board floor products.
Suspended timber subfloors flex across joist spans, which causes pile crease and rippling in carpet over time. We ply-raft the floor first — a layer of 9mm structural ply screwed across the joists removes the flex entirely. On ground floors we specify a breathable felt underlay to allow air circulation through the boards beneath, preventing moisture build-up that can cause mould. All ply preparation is included in your fixed price.
The 1930s semis in Kenton and Wealdstone (HA3) have suspended timber or mixed ground floors in generally good condition. Lower moisture risk than Harrow's post-war stock and well-suited to most floor types once the ground floor is appropriately prepared.

Post-war local-authority housing in the Roxborough area of HA1 and parts of Northolt Road has solid concrete ground floors with elevated moisture readings typical of properties built in the 1950s with early DPC membranes. Assessment before installation is essential.
Older solid concrete ground floors often carry elevated moisture readings — particularly in post-war builds where the original DPC has degraded. We test moisture at the home visit using a calibrated hygrometer before specifying any product. Where readings exceed 75% RH we install a heavy-duty DPM membrane beneath the gripper rods, sealing the slab before fitting begins. The DPM test and membrane are included in your fixed-price quote — never charged as an extra.
New-build apartments in the HA1 St Ann's Road regeneration area and the wider Wembley HA9 development corridor have liquid-screed floors with wet underfloor heating. These are flat, clean substrates for LVT and engineered wood provided UFH-rated products are specified.
Carpet can be used over underfloor heating, but underlay selection is critical. We specify either a low-tog bonded-foam or rubber-backed underlay with a combined thermal resistance of ≤0.15 m²K/W — exceeding this value reduces heating efficiency and can cause the system to overheat. The UFH-compatible specification is confirmed in writing on every quote so you and your heating engineer both have the documentation.
Yes — all of HA1, HA2 and HA3 including Harrow-on-the-Hill, South Harrow, Kenton, Wealdstone, Roxborough and Pinner. Free home visit with no call-out charge.
We apply 6mm structural ply over the existing boards to create a flat base that prevents pile crease. This is included in the fixed price and is standard preparation for HA1 and HA2 Edwardian properties.
Yes. We test moisture at the home visit and, where readings are elevated, install a DPM membrane before gripper rods and underlay — included in the fixed price. Roxborough and Northolt Road properties are among the areas where this is most routinely required.
Yes — we specify a low-tog underlay (≤0.15 m²K/W) within the UFH system's thermal resistance specification. UFH compatibility is confirmed in writing on the quote.
An 80/20 wool-blend twist pile suits the generous proportions of Edwardian rooms in HA1 and HA2 — natural texture, good durability and sympathetic to the period character. We bring samples to your home so you can choose in your own light.
We come to you with samples, measure up and give you a fixed price on the day. No obligation, no deposit. See our carpet fitting service or all flooring options in Harrow.
