Fire door surveys
We can survey existing doors across a property or portfolio, grading each as compliant, repairable or requiring replacement, with a photographic report.
Fire door installation in Greenwich
Lian Construction supplies and installs FD30 and FD60 fire doors across London for landlords, letting agents and block managers, fitted to the gap tolerances, seals and closer settings that make a certified fire door actually work as tested. We handle single door replacements for individual flats and full programmes across blocks and HMO portfolios, working around occupied properties and reporting back with photographic evidence for fire safety files and licensing inspections.
Greenwich overview
A large stock of Victorian and Edwardian houses with essentially no dedicated roofing competitor coverage. Greenwich falls well within the South East London ground Lian Construction covers on a regular basis. For fire door installation work in Greenwich, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.
Greenwich has a large stock of Victorian and Edwardian houses, much of it terraced or semi-detached, built in the decades either side of 1900 as London's suburbs expanded along the riverside and rail lines. As with similar housing across inner and near-inner London boroughs, roofs on these properties are typically slate or clay tile, often with parapet walls, valley gutters, and multiple original chimney stacks. Many houses will have had partial re-roofing, loft conversions, or rear extensions at some point over the past century, which means roof coverings and detailing are frequently mixed ages even on a single property. Bay windows with their own small roofs, and shared or party-wall guttering between terraced neighbours, are common features that need particular care during repair work. Given the age of this housing stock, issues such as slipped or missing tiles, ageing lead flashing around chimneys, and worn valley gutters are the kind of thing homeowners in Greenwich are likely to encounter periodically, rather than one-off problems. Property condition varies a good deal street by street depending on maintenance history, so what one house needs can differ significantly from its neighbour.
With a large stock of Victorian and Edwardian houses and essentially no dedicated roofing competitor coverage in the area, homeowners and landlords in Greenwich are often left choosing between general builders who treat roofing as a sideline, or firms based further afield who may not prioritise smaller local jobs. This gap tends to show up most clearly with urgent repairs, where a slipped tile or a leak after a storm needs someone who can attend quickly rather than fit the job in around larger contracts elsewhere. It also affects planning and quoting for larger work such as full re-roofs or chimney repairs, where a lack of specialist local knowledge can mean longer lead times or less accurate initial assessments. For landlords managing older rental stock, this matters because roof issues left unresolved tend to escalate into damp and interior damage, which is more disruptive and costly to fix than catching problems early. Homeowners undertaking wider refurbishment work, such as loft conversions or extensions, may also find it harder to coordinate roofing specifically as part of a bigger project if there isn't a contractor locally who covers that trade in depth. In practice, this means demand for reliable, responsive roofing and refurbishment work in Greenwich likely outstrips the readily available supply.
Given the concentration of Victorian and Edwardian houses in Greenwich, conservation area and, in some cases, listed building considerations are worth checking before starting roofing or exterior refurbishment work. As in many outer and inner London boroughs with older housing stock, parts of Greenwich may fall within conservation areas, where changes visible from the street, such as replacing roof coverings with a different material, altering rooflines, or adding roof windows to a front elevation, can require planning permission even where similar work elsewhere would be permitted development. Chimney stacks and original architectural detailing are often specifically protected in these areas. It's worth checking with the local planning department or a surveyor early on, since retrospective permission is harder to secure than getting it sorted before work starts. This doesn't apply to every property, and plenty of routine repairs and like-for-like replacements fall outside these controls, but it's a sensible thing to verify given the age of the housing stock.

A certified fire doorset is not just a heavier door. FD30 and FD60 leaves have a dense mineral or timber composite core, usually chipboard or particleboard bonded with additives that char and insulate rather than burn through, faced with veneer, laminate or a paint-grade skin. Around the door edge and matching frame rebate, a continuous intumescent strip, usually graphite-based, sits in a groove and expands under heat to seal the gap and stop fire and smoke passing through, working alongside a cold smoke seal, either a brush pile or a fin, that blocks smoke at ambient temperature before the intumescent activates. The frame has to be matched to the leaf as tested, not just any timber frame of the right thickness. Ironmongery is part of the tested assembly too. FD60 leaves typically weigh 40 to 50kg and need at least three, often four, hinges fitted with intumescent hinge pads, and any lock, latch or vision panel has to be within the scope of what the doorset was certified with. A colour-coded certification plug or label on the top edge of the door references the test or assessment it was built to, which is what an inspector or fire risk assessor is looking for when checking a door on site.

Questions
Greenwich is part of our regular South East London coverage, so once we've surveyed the property we can usually confirm a start date quickly. Send the address and scope and we'll arrange the next step.
Yes. Greenwich falls within the area Lian Construction serves across Greater London.
Old doors and frames are removed and taken off site as general construction waste, either with us directly or via a skip on larger programmes. They're not usually salvageable for reuse elsewhere in the property, since an old timber door that wasn't fire rated has no certification value even if the timber itself looks sound. If a landlord wants to keep a period front door for its character rather than dispose of it, that's worth flagging before work starts so it can be stored rather than skipped, though it obviously can't then be reused as the fire-rated replacement.
It doesn't have to, but it usually should for the room to look finished. Certified doorsets are available pre-finished in a range of veneers, laminates or as a paint-grade skin ready for site decoration, and we'd normally match the new door to the existing joinery, skirting or other doors in the property where that's straightforward. On a single flat entrance door replacement in a block, matching the finish used on neighbouring doors is often expected by the managing agent for consistency along the corridor, and it's worth checking that before ordering rather than after.
It depends on the damage. Superficial scuffs or scratches to the surface finish don't usually affect the door's fire performance and can be touched up or repainted, taking care not to cover the seals or certification label. Deeper gouges, holes, or damage that's gone through the facing into the core are a different matter, since the certified performance relies on the leaf being intact as tested, and a door in that condition should be assessed rather than assumed to still be compliant. We can survey a damaged door and advise whether it's repairable or needs replacing.
FD30 doors resist fire for 30 minutes and are standard for HMO bedroom and kitchen doors. FD60 doors give 60 minutes and are used in higher-risk locations.
