Lewisham · SE8 · Cat flap fitting
Same-week slots · Fully insured · Local Deptford fitters · Fixed written pricesWe provide cat flap fitting in Deptford SE8 for houses and flats around Deptford Market Yard. From £75, quoted in writing before the visit, with 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 Doors are checked for glazing and fire rating before cutting.


Overview
Booked mostly by social-housing-led households around Deptford, cat flap fitting here covers supply-free fitting from £75. With 83% of Deptford's 7,370 homes in flats, lift access and stair carries in SE8 shape the slot length we hold.
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. Market-day closures on Deptford High Street, narrow creek lanes and estate lifts.
Most cat flap bookings are within 48 hours and take a single short visit. Deptford (Southeastern) is the nearest station, so a SE8 visit rarely needs a whole morning set aside.
We expect precast concrete panels and dense blockwork in SE8, often with surface conduit, measured on the walk in from Deptford (Southeastern) rather than assumed from a map in SE8, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is Deptford gives us drilling blind into a panel with reinforcement or a buried cable behind it, where 24% owner-occupation means the same home is booked again rather than a new tenant each year.
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 Deptford
Deptford SE8 is Georgian and early Victorian and social-housing-led: 83% of homes here are flats and 17% are houses, across 7,370 households (ONS Census 2021).
Because 28% of Deptford is privately rented and 48% socially rented, a lot of SE8 work is agreed with a landlord or managing agent rather than the person opening the door.
Deptford substrates run to precast concrete panels and dense blockwork in SE8, often with surface conduit, measured on the walk in from Deptford (Southeastern) rather than assumed from a map. Nothing is drilled until the wall has been sounded, because Deptford gives us drilling blind into a panel with reinforcement or a buried cable behind it, where 24% owner-occupation means the same home is booked again rather than a new tenant each year is the mistake that costs a SE8 customer twice.
Market street, the Albany and the creek-side yards of the old naval dockyard. That character decides the practical detail of cat flap fitting here far more than the borough boundary does. Deptford is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
On access, market-day closures on Deptford High Street, narrow creek lanes and estate lifts — one reason 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. Fitters travelling in use Deptford (Southeastern).
