The reliable way to hire a tradesperson

Am thinking of buying a house that has a Memera 2000 white plastic consumer in the garage above which appear to be some damp roof planks. I can supply a photo, Just wondering how old such a fuse box is likely to be and costs of replacing?

I had a patch of mould on my carpet which was very smelly.I treated it with baking soda vinegar and salt.The smell eventually went.I had left a window Slightly open all winter in the dining area adjoining my lounge.I bought a plastic mat to cover the stain and when I lifted it up it had started it up again the mould was rancid.I decided to have new carpet but when the fitter came to measure I asked him what he thought it was.He thought condensation.I have since lifted the carpet up round the edges and the floor is wet .99 per cent in places.What is your opinion.

I’m looking for the most cost-effective way to paint the front of my three-story Victorian house with a bay window. I can paint the ground and first floors myself, but I need a safe way to access the second floor. What would be the cheapest option? Full scaffolding is very expensive, and I’d rather avoid drilling into the brickwork to install any fixings. Thank you!
