Down by the water, Strand-on-the-Green keeps a run of much older riverside cottages and terraces that sit directly on the Thames towpath, some dating back to the eighteenth century. That proximity to the river matters a great deal for damp diagnosis. Strand-on-the-Green and the streets nearest the Thames sit on a naturally high water table, and properties there are exposed to occasional tidal flood risk as well as constant ground moisture pushing up through solid brick and stone foundations. Further back from the river, around Chiswick High Road, Turnham Green and Gunnersbury, the housing is a mix of Victorian terraces converted into flats and later infill development, with the usual pattern of failed damp proof courses and hard cement repairs. Bedford Park's houses were built to a consistent architectural pattern in the 1870s and 1880s, with decorative brickwork, tile-hung gables and bay windows that are now protected by conservation area rules, so any repair has to match the original materials and detailing rather than take a generic approach. Where a house near Strand-on-the-Green or the riverside has taken in flood water at some point, the drying-out and repair process is different again from ordinary rising damp, and needs to be assessed on its own terms rather than treated as a standard chemical DPC job. We survey free of charge across Bedford Park, Grove Park, Strand-on-the-Green, Chiswick High Road, Turnham Green, Gunnersbury and the wider Chiswick riverside, with calls taken Monday to Friday 8am to 8pm and Saturday 8am to 1pm. ### Areas we cover within Chiswick - Bedford Park - Grove Park - Strand-on-the-Green - Chiswick High Road - Turnham Green - Gunnersbury - Chiswick Green - Chiswick Riverside ### Property types we work on Bedford Park's tile-hung Victorian terraces and villas, larger detached and semi-detached houses in Grove Park with basements, and the older riverside cottages and terraces at Strand-on-the-Green. ### Common Chiswick requests Rising damp diagnosis in solid-wall Victorian terraces, basement and lower-ground waterproofing in Grove Park, and riverside damp linked to the high water table and flood exposure near the Thames. ### Working within conservation areas Much of Bedford Park and parts of Strand-on-the-Green sit within conservation areas, and we specify repairs and materials that respect the original brick, render and joinery. ### When you can reach us - Monday8am – 8pm - Tuesday8am – 8pm - Wednesday8am – 8pm - Thursday8am – 8pm - Friday8am – 8pm - Saturday8am – 1pm - SundayClosed Services in Chiswick ## Every service available across Chiswick ### Rising damp treatment A failed damp proof course is diagnosed, treated with an accredited Sovereign or Wykamol system and replastered to a decoration-ready finish, priced as a fixed sum before any work starts, and guaranteed for ten years.

Local damp problems ## Why Chiswick properties get damp Chiswick's closeness to the Thames sets it apart from many of the areas we cover. A high water table near the river, combined with solid Victorian brick construction that predates any reliable damp proof course, gives rising damp and penetrating damp more than one route into the building. Further from the river, in Bedford Park, Turnham Green and around the High Road, the more familiar Victorian faults dominate: failed or absent DPCs, hard cement pointing, and converted flats with shared external repairs. ### High water table near the Thames Strand-on-the-Green and other streets close to the river sit on ground that stays saturated for much of the year, pushing moisture into solid brick and stone foundations regardless of the condition of any damp proof course. ### Occasional flood exposure Properties nearest the towpath can take in water during exceptional tides or river flooding, leaving salts and residual moisture in the walls that need a proper drying-out and repair plan rather than a quick redecoration. ### Failed slate and absent DPCs in Victorian terraces Bedford Park and the streets around Turnham Green were largely built before reliable damp proof courses were standard, and any slate DPC that does exist has usually failed after well over a century. ### Cement pointing on decorative brickwork Bedford Park's tile-hung, decoratively bonded brickwork was designed to breathe, and hard cement repointing traps moisture that then shows as damp patches and spalling brick faces. ### Basement water pressure in Grove Park Larger houses in Grove Park with a basement or lower-ground floor take on water under hydrostatic pressure, which needs structural waterproofing rather than a surface damp-proof paint. ### Converted flats and shared responsibility Where a Victorian terrace has been split into flats, roof, parapet and external wall defects are frequently a freeholder or managing agent's responsibility rather than a single leaseholder's.

In detail ## Damp proofing across Chiswick in detail ### Rising damp near the Thames and the high water table A survey at Strand-on-the-Green or another riverside Chiswick address often finds a tide mark and salt staining that extends higher up the wall than we would expect further from the river, a sign of the naturally high water table rather than a single point of DPC failure. Once confirmed, we inject a chemical damp proof course using an accredited Sovereign or Wykamol system and follow with salt-retardant replastering after the contaminated plaster has been stripped back. Where a property has previously taken in flood water, the walls may hold residual salts and moisture that keep reappearing after redecoration until they are properly identified and treated, so the survey looks at flood history as well as the current tide mark. ### Repairing Bedford Park's decorative brickwork Bedford Park's houses were built with a consistent, decorative use of brick, tile-hanging and render that gives the area its conservation status. A great deal of the damp reported in these houses is not rising damp at all but the result of hard cement pointing or render applied over the original soft brick, trapping moisture that the wall was designed to release through the mortar joints. Repointing in a mortar matched to the original, and removing hard cement render in favour of a breathable finish where the conservation area allows, restores the wall's ability to manage moisture rather than fighting it with sealants. ### Basements and lower-ground rooms in Grove Park The larger detached and semi-detached houses in Grove Park often include a basement or lower-ground room, and given the local water table, bringing one into daily use as a study, gym or extra bedroom needs proper structural waterproofing rather than a coat of waterproof paint. That generally means cementitious tanking bonded to sound masonry, or a cavity drain membrane system with perimeter drainage and a pumped discharge, depending on how the water is reaching the space. Junctions at the floor-to-wall interface, around service penetrations and at any external light wells are where these systems most often fail if not detailed properly, so we specify and install to the accredited system's full specification. ### Flood-affected and riverside cottages The older cottages and terraces at Strand-on-the-Green sit right against the Thames towpath, and some have taken in water during exceptional high tides over the years. Drying out a flood-affected wall properly takes longer than treating ordinary rising damp, and often needs a period of controlled drying before replastering to avoid trapping residual moisture behind new plaster. Where flood exposure is a recurring risk, we discuss practical measures alongside the damp treatment itself, so the repair holds up the next time water levels rise. ### Terraces and conversions around Turnham Green and the High Road Away from the river, the Victorian terraces around Turnham Green and Chiswick High Road follow a more familiar pattern: solid brick walls without a reliable original damp proof course, later converted into flats with split responsibility for the roof and external walls between leaseholders and freeholders. Where a defect is a building-wide responsibility rather than a single flat's, we identify that clearly at survey and put it in writing so it can be taken to the managing agent without a dispute over the diagnosis. Questions ## Damp proofing in Chiswick, common questions Which parts of Chiswick do you cover?Bedford Park, Grove Park, Strand-on-the-Green, Chiswick High Road, Turnham Green, Gunnersbury and the wider Chiswick riverside, plus the surrounding streets. Does being close to the Thames make damp worse in Chiswick?It can. A naturally high water table near the river pushes more ground moisture into solid brick and stone foundations, and some riverside properties have also been affected by flooding, both of which are considered at survey. Do you work on basements in Grove Park?Yes. We design and install structural waterproofing, cementitious tanking or cavity drain membrane systems, depending on how water is reaching the space and what the local ground conditions are. My house is in a Bedford Park conservation area, can you still repoint it?Yes. We repoint and repair using materials and detailing that match the original brickwork, tile-hanging and render, consistent with conservation area requirements. How much does damp proofing cost in Chiswick?It depends on the wall construction, proximity to the river, replastering required and whether basement waterproofing is involved. The survey and written fixed-price quotation are free. My house near the river was flooded, can you dry it out?Yes. Flood-affected walls need a period of controlled drying and salt-retardant replastering rather than the standard rising damp treatment, and we assess that at survey. I own a flat in a converted Chiswick terrace, will you deal with the freeholder?We will identify whether the defect is within your flat or a shared external repair and put the diagnosis in writing so you can take it to the freeholder or managing agent. Is my damp likely to be rising damp or something else?In Chiswick it could be a failed DPC, cement pointing trapping moisture, a high local water table, or previous flood exposure. The survey identifies which before any treatment is proposed. Is your work guaranteed?Damp treatment carries a 10-year company workmanship guarantee plus a separate 10-year QANW insurance-backed guarantee. Building works carry a 6-month workmanship guarantee. Is the survey free?Yes, along with the diagnosis and the written fixed-price quotation, with no obligation to proceed.
