Good points: arrived in good time and at short notice. Work completed relatively quickly and appeared to be of a good standard.
Bad points: damaged plaster on wall, (pipe was under the floor, not near the wall which was damaged), left a foot print on another wall - both had to be redecorated. Charge for "materials" was excessive, knowing how much the material would have cost. Easy way to jack up what seemed to be a somewhat reasonable price for an urgent call out.
Neutral points: refunded material cost to cover the damage to the wall. Price to complete the job (excluding materials) was reasonable. Was very responsive and I very much appreciate them being able to accommodate in such short notice.
Overall, I'd probably shop around in the future if I had more time to do so. Good if you need a quick or urgent job doing.
