Haringey · N10 · Cat flap fitting
Same-week slots · Fully insured · Local Muswell Hill fitters · Fixed written pricesBooking cat flap fitting near Alexandra Palace and Park? Steep approach roads, tight parades with short loading bays and long garden paths, and that is planned into the slot rather than discovered on the day. Prices start at £75 and are fixed before we travel. Doors are checked for glazing and fire rating before cutting.


Overview
Cat flap fitting in Muswell Hill N10 is a fixed-price visit for owner-occupier-led homes in Haringey, most of them mainly Edwardian. 5,479 households sit inside this N10 patch, 63% of them flats, so we quote on access near Alexandra Palace and Park rather than a London average.
How it works
Step 1
Timber, uPVC, composite, glass or masonry — plus what is behind it. A cavity wall or a glazed panel changes the job completely.
Step 2
Measured to your cat's chest height, so an older or arthritic cat still uses it in two years' time.
Step 3
Template marked, cut from both faces to avoid blow-out, and the edge lined, capped or sealed.
Step 4
Flap fitted square, sealed against draughts and rain, and the fixings drawn up evenly so the frame does not bow.
Step 5
Microchips registered, curfew set if you want one, and the flap left in training mode with the mess cleared.
Why choose us
Fitters carry £5m public liability cover. We check leasehold and landlord consent before cutting anything, and we will not cut a communal fire door — that would void its rating and the block's fire strategy.
One fitter for doors and panels; two where a wall tunnel is core-drilled and the debris has to be carried out of a flat. Steep approach roads, tight parades with short loading bays and long garden paths.
Most cat flap bookings are within 48 hours and take a single short visit. Highgate (Northern) is the nearest station, so a N10 visit rarely needs a whole morning set aside.
We expect lath and plaster over timber studs in Muswell Hill, with solid brick on the party and external walls, measured on the walk in from Highgate (Northern) rather than assumed from a map in N10, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is a plasterboard plug spun into lime plaster in N10, which crumbles the key and drops the panel, and with 35% of homes here privately rented, it sets the booking date as often as the job does.
Fixed prices
| Job | From | Typical time | What sets the price |
|---|---|---|---|
| Timber door | £75 | 45–60 min | Cut, chamfered and sealed so the door edge does not swell in winter. |
| uPVC door panel | £95 | 1–1.5 hrs | The panel is cut in place with the frame protected, and the cut edge capped so water cannot track in. |
| Composite door | £120 | 1–2 hrs | A composite has a foam core between two skins; both faces must be cut cleanly and the core sealed. |
| Brick or block wall, up to 350mm | £190 | 2–3 hrs | Core-drilled both sides with a tunnel liner fitted, so the cavity is never left open. |
| Glass panel — cut-out supplied by a glazier | £110 | 1 hr | Toughened glass cannot be cut on site; we template it, fit the replacement pane and set the flap. |
| Microchip flap set-up and training mode | £25 | 15–20 min | Chips registered, curfew and selective entry configured, and the flap left on training setting. |

Scope
Sulltan is the best handyman in London. He is very reliable and professional. I highly recommend.

Working in Muswell Hill
Muswell Hill N10 is mainly Edwardian and owner-occupier-led: 63% of homes here are flats and 37% are houses, across 5,479 households (ONS Census 2021).
Because 35% of Muswell Hill is privately rented and 8% socially rented, a lot of N10 work is agreed with a landlord or managing agent rather than the person opening the door.
Muswell Hill substrates run to lath and plaster over timber studs in Muswell Hill, with solid brick on the party and external walls, measured on the walk in from Highgate (Northern) rather than assumed from a map. Nothing is drilled until the wall has been sounded, because a plasterboard plug spun into lime plaster in N10, which crumbles the key and drops the panel, and with 35% of homes here privately rented, it sets the booking date as often as the job does is the mistake that costs a N10 customer twice.
Edwardian shopping parades on a hilltop with wide views across London. That character decides the practical detail of cat flap fitting here far more than the borough boundary does. Muswell Hill is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Steep approach roads, tight parades with short loading bays and long garden paths. Nearest station is Highgate (Northern), and one fitter for doors and panels; two where a wall tunnel is core-drilled and the debris has to be carried out of a flat.

Timber door starts at £75 in Muswell Hill on N10 jobs, with 37% of Muswell Hill homes being houses, and every job is quoted as a fixed written price before a fitter is booked. The material sets the price. Timber is quickest, uPVC and composite need capping across N10, with 63% of homes here being flats, and a masonry wall means core drilling and a lined tunnel.
Yes — £95, an hour to 90 minutes. The panel is cut in place and the edge capped across N10, so the door stays weatherproof. If it is glazed, a glazier supplies a pane with the cut-out around Highgate (Northern).
Yes, in writing. 35% of Muswell Hill homes are privately rented on this side of Haringey, with 63% of homes here being flats, and a flap cut without consent is a common deposit deduction. Send the email and we fit to its conditions on N10 jobs.
Yes, from £190 for a wall up to 350mm — the usual answer in Muswell Hill across N10, with 57% owner-occupation locally — and a median age of 41 in this neighbourhood, where 63% of homes are flats with glazed back doors: we core-drill and fit a lined tunnel.
Steep approach roads, tight parades with short loading bays and long garden paths across N10. Where a permit or a suspended bay is needed in London Borough of Haringey it is itemised on the quote before the visit, never added afterwards on this side of Haringey, with this being London Borough of Haringey territory.
Fitters carry £5m public liability cover. We check leasehold and landlord consent before cutting anything in Muswell Hill, with Haringey parking rules in play — and this being a short walk from Highgate (Northern), and we will not cut a communal fire door — that would void its rating and the block's fire strategy. That paperwork is what most Haringey letting agents and managing agents ask for before work starts in a leasehold flat around Highgate (Northern), with 31% one-person households here.
Cutting toughened or laminated glass on site — it must be replaced by a glazier; Fire doors in communal areas around Highgate (Northern) — and this being London Borough of Haringey territory, with this being a short walk from Highgate (Northern), where a cut-out would void the fire rating; Structural openings through a lintel or an insulated cavity closer without a survey. Anything outside that scope is quoted separately so the Muswell Hill N10 price you agree is the price you pay across N10, with 57% owner-occupation locally.
