The reliable way to hire a tradesperson

How’s best to treat any damp due to condensation on the interior of the house in the corners? What paint should I be using? The damp is more service level and not in the plaster.

We have 3 x BULB CEILING fittments that are BAYONET fittings. NOT the usual 2 PINs for a UK Bayonet BUT 3 Pins. Yet, we can't EASILY AFFORD the 3Pin bulbs as they are Far & Few between also being at the top end of the COSTs. SO..... What is the best, Cheapest option to follow?

Hi, I have recently undercoated doors and frames with Dulux trade undercoat. They are different woods, and even with four coats of undercoat, they are still showing as different shades of white, the doors are more cream. I would like the finish to be uniform white. Will the topcoat do that, or should I Zinser bin first? Or will Dulux Once solve the problem? I don't really want to use Dulux Once. Rather use normal satinwood. Grateful for your advice.
