Same-day lock change & insurance-grade upgrade across South Croydon — BS3621 5-lever mortice for Edwardian and inter-war timber doors through Selsdon, Sanderstead, Croham Hurst and Birdhurst; anti-snap euro cylinders for the uPVC and composite rear extensions; full moving-in re-keys for new family homes. Fixed price first, no call-out fee, Croydon-based engineer on the van.
South Croydon is the older, leafier, owner-occupier side of the borough — 1920s and 30s suburban semis and detached homes, Edwardian period stock through Croham and Birdhurst, and pockets of inter-war estates around Selsdon and Sanderstead. The doors here are different from the CR0 town centre, and so are the locks they want.
Across Selsdon, Sanderstead, Croham Hurst, Croham Manor Road, Birdhurst Rise and the Selsdon Vale avenues, original solid-timber front and back doors take a 5-lever BS3621 mortice deadlock as the main lock (kitemarked for insurance) alongside a Yale 89 or Union 1332 nightlatch above. We fit these from £180 and supply a paperwork-ready fitting receipt for your insurer.
For the 1990s–2010s composite and uPVC doors on rear extensions and replacement front doors — common across the inter-war housing stock — we change euro cylinders from £135 and upgrade to SS312 Diamond anti-snap (Ultion, Avocet ABS, Yale Platinum) from £200. Lock-snapping is the no.1 forced-entry attack on uPVC across the UK and South Croydon's family homes are common targets.
Whether you've just completed on a CR2 home, lost a set of keys after a Croham Hurst walk, want every external door re-keyed in one visit, or just need an honest fixed quote for an anti-snap upgrade — book a same-day slot or pre-book a time that suits you. From £89 fitted, fixed price first, no call-out fee.
Same Croydon-based engineer, same fixed-price-first promise, same workmanship warranty. The lock fitted changes depending on whether it's an Edwardian Selsdon timber door, a 1990s Sanderstead composite, or a 2010s rear-extension uPVC.
Insurance-grade 5-lever kitemarked mortice deadlock for Edwardian and inter-war timber doors across Selsdon, Sanderstead, Croham Hurst and Birdhurst. Period-sympathetic finish on conservation-area stock around Croham Manor Road.
From £180 fittedStandard cylinder swap for the uPVC and composite doors on rear extensions and replacement front doors common across Selsdon and Sanderstead. Measured flush before fitting — proud cylinders are exactly what snap attacks target.
From £135 fittedSS312 Diamond or TS007 3★ cylinders — Ultion, Avocet ABS, Yale Platinum. The standard recommended upgrade for every pre-2011 uPVC and composite door across CR2 — stops the no.1 forced-entry attack on UK family homes.
From £200 fitteduPVC dropped, key won't lift, handle gone floppy? We swap just the failed gearbox (Fuhr, Maco, GU, Yale, Lockmaster) rather than the full multi-point strip — keeps the door, saves the cost. One visit, in stock on the van.
From £350 fittedJust completed on a Selsdon semi or a Sanderstead detached? Previous owners, agents and contractors may still hold keys. We change every external lock (front, back, side, garage) on completion day — receipt with lock model and key count for insurance and conveyancing files.
From £89 per doorPolice-recommended C-rated key safes mounted into masonry — Burton, Supra C500, Master Lock 5440. Ideal for the carer/cleaner/gardener access common around Sanderstead and Selsdon family homes, and for holiday lets backing onto Croham Hurst.
From £150 fittedNo call-out fee. Fixed price quoted before any tool comes out of the bag. Same-day if the diary's open; otherwise a pre-booked slot that fits your move-in or contractor timeline.
Tell us the CR2 postcode, the door type (Edwardian timber? 90s uPVC? new composite?), and the lock brand stamp if you can see one. Two minutes is enough to quote a fixed price and book a slot — usually same day in South Croydon.
Croydon-based, DBS-checked, ID badge on. We assess the door, measure the cylinder or mortice pocket, confirm the price, and check whether you need a basic swap or a BS3621 / anti-snap upgrade for insurance.
Old lock out, new lock in, every key tested in both directions. Fitting receipt with the lock model and key count for your insurer or conveyancing file. 12-month workmanship warranty. Card or cash on the day.
No call-out fee. No "from £39" loss-leaders. The price below is what you pay — parts, labour, fitting receipt, 12-month workmanship warranty included.
Same engineer, same van — but the lock we fit changes depending on whether it's a Birdhurst Edwardian timber front door, a Selsdon 1930s solid-oak side door, a Sanderstead composite, or a Croham Hurst-edge replacement uPVC.
Pre-1939 solid-timber front and back doors across CR2's older streets — South Croydon proper, Croham Manor Road CA, Birdhurst Rise, Sanderstead village core. We fit BS3621 kitemarked mortice deadlocks alongside a quality nightlatch, period-sympathetic finishes available for conservation-area properties.
1920s–30s suburban semis and detached homes on the wide avenues through Selsdon Vale, Upper Selsdon Road and Limpsfield Road. Many still have original heavy timber front doors (BS3621 fit) plus a uPVC or composite rear door (anti-snap upgrade target).
Glass-reinforced composite doors are the standard CR2 replacement front door of the last 15 years. They run a euro cylinder inside a multipoint strip. We upgrade to Sold Secure Diamond anti-snap cylinders and check the gearbox tolerance while we're there.
Rear extensions and garden-facing French/patio doors backing onto Croham Hurst, Selsdon Wood and the suburban green-belt edge. These need anti-pick high-security cylinders and where possible key-alike with the front so one key opens both ends of the property.
We've been running a Croydon-based engineer van out of CR0 since 2015 — that's 10+ years of changing locks on the same Edwardian semis, inter-war Selsdon detached homes and Sanderstead composite-doored extensions over and over. We know the period-door quirks, the brand fits and the insurance grades before you've finished your sentence.
No call-out fee, no surprise charges, no upsell. You get a fixed price first, a paperwork-ready fitting receipt with the lock model after, and a 12-month workmanship warranty as standard.

From Birdhurst and Croham Manor Road through Selsdon and across to Sanderstead village — one engineer, one number, every CR2 postcode. Sitting between Croydon town and the Surrey green belt.
Three recent CR2 jobs in three different sub-areas. Every review is from a verified Google customer.
We completed on a 1925 semi just off Upper Selsdon Road and the front door still had the original Edwardian mortice. They came out the same afternoon, fitted a Union BS3621 plus a new Yale 89 nightlatch, and supplied a paperwork-ready receipt straight to our insurer's email. Felt safe by sunset.
Our composite back door on Sanderstead Road had the original builder's cylinder fitted in 2012 — basic Yale, sticking out a few mm. The engineer measured the cylinder before fitting, swapped it for an Avocet ABS Diamond, realigned the keep, tested everything twice. No upsell, fixed quote, in and out in 30 minutes.
Moved into a 1930s detached on the edge of Croham Hurst woods and wanted everything re-keyed. Six external locks (front, back, side, garage personnel, garage up-and-over, summer house). All done on the day of completion, all keyed identically where the lock allowed it, all on one labelled keyring. Genuinely impressed.
Eight questions we hear week-in, week-out from South Croydon residents, movers and landlords.
