Hi, I live in Brockley, SE4 but wanted to add to this thread. Apex Direct Promotions is a company selling external wall coatings. I signed up for a free external wall survey at the weekend thinking the company did all kinds of external maintenance (when I booked the appointment on the phone the very nice lady said they specialised in all external maintenance). However the salesman who arrived tonight was highly suspect (despite being a very nice man) and would not answer even a single direct question on what his company did. I booted him out after 20 minutes. Since then I've found this thread and others on Apex being a hard-sell, overpriced wall coatings company, which makes sense given my experience tonight. Do not sign up for any door step sales pitches for free external wall surveys, or entertain anyone saying they are from Apex Direct Promotions Ltd or Andura.
