What our customers say
I needed urgent mould removal before building works started. The team surveyed, cleaned and gave us the all clear the same day.
My landlord instructed Active to dry out our living room after a roof leak.
I have had mould in hallway and bedroom for 6 months. It's now gone. Thank you
So friendly and helpful. I didn't have any mould after all. They gave me free advice and didn't charge me.
Good lads, helped clean up a huge job in the old college buildings. Cheers
The team came and cleared mould from my kitchen. Very polite and helpful.
