Paint bubbling up and discoloured either side of back door in kitchen, approx 2 foot up from ground. The kitchen is an extension completed around 8 years ago (the house is a Victorian terrace).

Problem has existed for at least three years (since we bought the property). We have tried covering it up with stain stop but it just keeps coming back, and got worse during the wet weather last year.

Ideally I'd like some quotes this Friday 19th July, as I will be working from home.
