In between, you have six or seven real days to repaint marked walls, touch up skirting boards, seal yellowed bathroom silicones, and make the kitchen presentable for the next photo. We work in this format: small teams who come in, do what's necessary, and leave the same day or the next.

We diagnose circuits with a thermal camera, detect leaks without breaking the floor when possible, and repair the manifold or valves as appropriate.
