Terrace cleaning in Montlhéry (91310)
Moss removal and restoration of paving slabs, block paving and timber decking. Controlled pressure washing, matched to the surface.
The pressure is set to suit the surface, never the other way round. A concrete slab takes what a timber board or a sand-filled joint would not, so the setting can change from one part of a terrace to another. A test on an out-of-the-way corner settles the finish before the whole area is done.
Quotes are worked out per square metre: the area is measured on site and the condition of the surface assessed before a price is given. A terrace cleaned regularly takes less work than one left for several years. The quote is free.
What is different in Montlhéry
The old centre around the tower is full of small-pane windows, cleaned one pane at a time.
Small-pane windows hold what a single large sheet lets run off. Dust thrown up by the traffic, and the rain that drives it back down, settle into every corner of every glazing bar — the place a cloth reaches worst. It builds slowly, and in the end it sets hard.
Terraced town houses with wooden frames and glazing bars in the old centre, more recent detached houses around it. Two methods in one commune, and two very different amounts of time on site: in the old centre you count panes, not square metres.
