I've just bought a bungalow and the day before completion my vendor rang me about something and during the conversation said she was sorry she'd overwatered a plant in the back bedroom, and watermarked the carpet. Up until now, I've been too busy to think about it, it was covered in boxes.
A villager I am no longer frie'nds with because she used to drink drive with her kids in the car was also after this bungalow. I had bumped into her earlier in the year and she reluctantly congratulated me - then said 'I hope you can find the damp'. I thought she was just being her normal bitchy self.
I agreed to the vendor leaving a huge wicker chair in the front bedroom, and my curtain fitter came last week. I had to lug the big chair out of the bay so he could fit the rail - as he walked into the bay there was a huge 'crack' and he said he wasn't happy to continue. He pulled the carpet up and the boards are all rotten.
Once he'd left, I thought about the vendor's comment, as the back bedroom is quite dark and I wouldn't put a plant where the stain was - pulled the carpet up and had a shock. Not floorboards, it's all chipboard upto the concrete extension half of the floor, and it's all mouldy and black.
My surveyor came round and I've got dry rot in the floorboards of the front bay, and a severe condensation problem in the back bedroom.
He recommended a positive ventilation unit in the loft. I'd already bought a humidifer for the front bedroom due to the windows being soaked each morning, but it only does one room. The PVI is supposed to circulate the air in the whole bungalow.
Caveat emptor it is, sadly.
I would recommend trying to see the sub void. And if you have blocked up chimney breasts, do you have a ventilation slot?
