Page 1 of Builders/Plasterers advice needed

Evening all :-)

Have been having some rather nasty water ingress through the walls and over the windows in me front rooms.
Cutting a long story shortish, I'm three floors up (top floor) of the 1930s block of flats and the building's only clad in a single 9 inch brick. The managing agents are holding back as to whether they're responsible for the upkeep and protection of the brickwork and have even had the cheek to say that because of the unusual stormy weather (which has been fairly standard for this time of year in SE London) that there may not be anything they can do. However, I can't really hold my breath for them to make any sort of decision (48 flats in the block and everyone has a slightly different lease) before they take any sort of action and need some fairly drastic work done inside pretty sharpish.

So, basically..does anyone know any experts in stripping-back-plaster-before-re-rendering-inside-walls-with-proper-insulation-that-will-most-likely-involve-replacing-the-windows-as-well?..in my general area (Lewisham).or if not, has anyone had the same sort of issues with managing agents and am I likely to get some money off their insurance to help pay for the work?

Also, has anyone had any experience of ratedpeople.com?

etc

Apologies about the huge post, but thanks for reading...if you did. Getting a bit desperate :-(

As always, personal recommendation is best, failing that have used

http://www.checkatrade.com/

to find ppl to do jobs in the past/check on ppl we've had recommended to us.

I think the guy who did our bathroom said the main problem with ratedpeople (or if not that one, sites like it) is that the tradesman gets an alert, then has to pay to read it, spend time on an estimate etc, when it could be a time waster, but he's still out of pocket.

Cheers mate. Agree personal recommendations are the best, so I'm hunting for those too, but always good to check other sites. Just read some reviews of ratedpeople..and they're not necessarily that good. Will check checkatrade though!
