R&D Asbestos Surveys in the City of Westminster

A standard pre-purchase survey only looks at surface materials that are visible during a routine walkaround. Building Control and your structural engineer require an intrusive Refurbishment and Demolition survey because knocking down walls, splicing steel beams, or running new waste pipes breaks into concealed cavities. If your contractor cuts into an unrecorded asbestos insulating board firebreak or an old cement flue hidden inside a wall void, work stops instantly and the whole site gets sealed off.

The survey involves planned damage within the specific areas marked for alteration or demolition. We lift sections of floorboards, cut access hatches into plasterboard and timber boxing, pull back bath panels, and inspect hidden ceiling voids above suspended grids. Because we breach structural fabrics to check behind them, the work areas must be fully cleared of furniture and soft furnishings before we arrive on site.

In properties around Pimlico, Marylebone, and St John's Wood, older refurbishments often concealed asbestos during fireproofing upgrades. We frequently locate asbestos insulating board (AIB) collars around service risers running between floors, AIB packers behind steel joists, and asbestos cement flues walled into old chimney breasts or lath-and-plaster partitions. You also routinely find layers of thermoplastic tiles and black bitumen adhesive buried beneath later screeds, engineered timber, or carpet underlay.

Yes, you do not have to carry out a full building survey if you are only stripping out a kitchen, updating a bathroom, or knocking down a single dividing wall. We run a targeted refurbishment survey based directly on your architect’s drawings and proposed scope of works. We will only break into boxing, floors, and ceilings within the planned work boundary, leaving the untouched parts of the property undisturbed.

We use controlled, localised suppression techniques rather than tearing blindly into building fabrics. Before drilling or cutting an inspection port into boxing or pulling down a ceiling section, we inject or spray the material with a fibre-suppressing wetting agent and run a Class H vacuum directly at the tool face. Once we take our core sample and inspect the void, we tape up the cut edges and seal the opening so dust cannot migrate through the property.

You receive a comprehensive material register backed up by marked CAD floor plans that show every inspection point and sample location across the work zone. The report identifies the exact asbestos type, its location, condition, and whether it falls under non-licensed removal or requires an HSE-notified licensed contractor. This gives your principal contractor a clear, legal scope of works so they can schedule remediation and price the strip-out accurately before any trades start on site.
