Is there any companies in HULL for reparing a van after damp?

hi all.

i bought an 1990 elddis shamal XL last year for a dirt cheap price as it was in a little bit of a mess. I have now brought the van upto its former glory as you do. But as i was serching through the services papers that came with it and i had noticed that the front window seal had been replaced and sealed many of times right up to 2004. i had the vans chassis serviced last year just to make sure it was ok but nothing else, So after i read the service papers i went to the van and i just checked all over the front windows and i noticed some wood has risen from my knowledge of static vans and stories i had heard about damp in them, the alarm bells started ringing, so i checked in the locker box and to my shock the hole wood under the front of the van was wet wet wet. so i checked out the front windows and to my horror the left hand small window seal had no filling it what so ever so the water had been pooring in for some time. so i then went straight on ebay and bought my self a caravan cover. the van has been stood since around septempber as i havnt had the chance to use it.

i then got my friend of ours to store the van in his barn over the winter period, so it had chance to dry out and i placed a few warm air radiators that will dry it out. and just before it came out i resealed the window with sealant. the wood has no dried but has stained underneith.

Now after this i noticed the front boarding was completly wrecked by the water although this is not noticable from the naked eye, but when you feel it you can tell its soft and warpy kind of feeling, as well as woodwork underneith the window has risen and left a small gap.
just so i feel more complete as well as the van as far as im aware it was only that little part that was affected. i would really like all the boarding and woodwork replaced i would do it my self but hav no idea what i am doing and plus i hardly have any time carry a repair like this out, but i am no experienced caravanner and havent the faintest idea where to go. i have researched on the net, and i suspose i could send it to a caravan centre but no doubt it would cost me a bomb and to be honest it would not be worth it on a van of this age.

so if anybody could help me to locate or can give me any good caravan repair centres in or around the area of HULL in yorkshire, in the UK who specilise in damp repair then i would be most greatful to them.

thanks josh.
