West London borough close to Kingston and Richmond, with a mix of suburban housing stock needing general repairs and roofing. Hounslow falls well within the West London ground Lian Construction covers on a regular basis. For brickwork and repointing work in Hounslow, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.
Hounslow's housing stock is largely shaped by its position between the inner suburbs and the Thames-side towns of Kingston and Richmond, meaning much of the borough consists of suburban semi-detached and terraced houses built through the interwar and post-war expansion of west London. Rows of 1930s semis with bay windows and pitched tiled roofs are common, alongside pockets of Victorian and Edwardian terraces closer to older village centres, and later 20th-century estates further out. This mix means roof types vary across the borough: traditional pitched slate or tile roofs on older properties, and a mix of tile and flat-roof extensions on inter-war and post-war stock. General wear is the main driver of work - guttering, pointing, roof coverings and rendering that have simply aged, rather than anything structurally unusual. Many houses have had extensions or loft conversions added over the decades, which means roofline junctions, flashings and old extension roofs are often where problems show up first. For a homeowner, that typically means routine maintenance and repair work rather than large-scale rebuilds, though older properties can throw up surprises once you get up on the roof or open a wall.
Hounslow sits at the edge of west London's commuter belt, within easy reach of Kingston and Richmond, and demand for repair and roofing work tends to track the age of its suburban housing rather than any single trend. A lot of the borough's semis and terraces are now well past the point where original roofs, guttering and brickwork need attention, so ongoing maintenance and reactive repair work - fixing leaks, replacing worn tiles, sorting out damp - make up a steady share of the work available. Because Hounslow sits between higher-profile areas like Richmond and Kingston, some homeowners default to calling contractors based further out or in those neighbouring boroughs, which can mean longer wait times or higher call-out costs for straightforward repair jobs. That leaves room for a contractor who responds promptly to general repairs and roofing work without treating it as an afterthought to bigger projects. For landlords with rental stock in the borough, keeping on top of routine repairs also matters for avoiding bigger, costlier issues later, particularly with roofing, where a small leak left unaddressed can lead to more extensive internal damage.
Chimney stacks, garden walls and brick cleaning
Chimney stacks take the worst weather exposure of almost any brickwork on a London house, standing above the roofline with no protection and full exposure to wind-driven rain, and they're frequently the first place repointing failure and brick spalling show up. We repoint and repair stack brickwork, renew flaunching, the mortar fillet around the base of the chimney pots that sheds water away from the stack top, and rebuild sections where brick has deteriorated too far to repair in place, coordinating scaffold access with any roofing work happening at the same time where relevant. Garden and boundary walls are built to the same standard as house brickwork but usually weather faster, since they have no roof overhang for protection and often sit closer to ground moisture and vegetation than a house elevation does, and a garden wall showing bulging or leaning, rather than just failed pointing, needs assessing for its footing condition before any repointing is worthwhile. Brick cleaning removes paint, staining, algae or general dirt from a facade, and method matters as much as the result: soft-washing with a low-pressure water and appropriate cleaning solution lifts dirt and biological growth without damaging the brick face, while sandblasting or aggressive high-pressure cleaning strips away the harder, weathered outer surface of an older brick permanently, leaving it more porous and vulnerable to future frost damage. We avoid sandblasting on historic brickwork for this reason and would flag it as a risk to the fabric of the building rather than recommend it, even where it looks like the faster option.
Lime mortar vs cement mortar: why it matters
The single most important decision in repointing London's older brick stock is mortar type, and it's also the one most likely to be got wrong by someone unfamiliar with period buildings. Victorian and Edwardian houses were built with a soft lime mortar, typically a hydraulic lime such as NHL 3.5 mixed with sand, which is deliberately weaker than the brick itself. That's intentional: lime mortar is porous and slightly flexible, so it allows the wall to breathe and lets any moisture that gets in evaporate back out through the joints rather than through the brick face, and it also acts as a sacrificial layer, wearing and needing renewal over time rather than the brick itself taking the damage. Repointing with a hard, dense cement mortar, common practice for decades before the issue was well understood, reverses this relationship. Cement mortar is stronger and less permeable than the surrounding brick, so moisture that gets into the wall can no longer escape through the joints and instead gets forced through the brick face itself, which is significantly more vulnerable to frost damage than the mortar was ever meant to be. Over years, this shows up as spalling, brick faces cracking and flaking off as trapped moisture freezes and expands within the brick. Once a wall has been repointed in cement, reversing the damage means raking out the hard pointing, which is itself a slow, careful job to avoid damaging brick arrises in the process, and repointing again in an appropriate lime mix. Joint profile matters as much as mix ratio for both appearance and performance. Original Victorian pointing was often a simple flush or slightly recessed joint rather than the raised, ruled joint sometimes applied in later repointing work, and matching the original profile as well as the mortar colour keeps a repointed wall looking consistent with the untouched sections either side of it. We take a sample of sound original mortar where one exists, checking it against the new mix before repointing a visible elevation, rather than guessing at a shade that turns out to look patchy once it's dried and weathered in. We specify lime mortar as standard on solid-wall Victorian and Edwardian brickwork, matched in colour and joint profile to the original.
