When the building was constructed.
Four trades, with the asbestos question settled before any of them starts on an older building.
The places insulation goes are the places asbestos was used: roof sheeting, insulation board, pipe lagging. So in a pre-2001 building we get the inventory before anything intrusive, and if something suspect appears we stop. We also state the thermal resistance we will actually install, because premium entitlement depends on the figure achieved rather than on the word insulated.
When the building was constructed.
Before any intrusive work.
The thermal value, in writing.
Or stop, if asbestos appears.
On an area you agree to.
What will not come back.
Products used to their data sheets.
Removed through an authorised route.
We will tell you when a surface will not come back. Stone that has been sealed with an unknown product, render already breaking down, a floor stained through its finish: aggressive cleaning on any of those makes it worse rather than better. Waste from cleaning leaves through an authorised collector, which is the part nobody sees and the part that matters.
Work on a dwelling carries compulsory ten-year liability insurance in Belgium, and a contractor who cannot show it should not be working on your house. Ours is in place. On repointing we match the mortar to the brick rather than to convenience, because a mortar harder than the brick destroys the brick instead of protecting it.
Substrate, movement and damp.
Mortar to the brick, not to habit.
To the agreed detail.
Site left as we found it.
Substrate moisture content.
In the room, not the van.
With proper expansion gaps.
Snagged before handover.
Wood moves, and almost every failed floor failed because of moisture or because it was laid too soon. We measure the substrate rather than judging it by eye, we let boards acclimatise in the room they will live in, and we leave the expansion gaps that make a floor look slightly unfinished at the edges and stay flat for years.
