Accepted an offer on our house of 495. Buyer had a survey done and it's come back with results that have left me a bit in shock. Firstly it says the external wall insulation was poorly installed and doesn't meet "standards" (whatever that means, I only have the buyer's interpretation, not the surveyor's report) and needs more passive ventilation because it's causing issues with damp.
Secondly, we have an issue with condensation in the loft in winter, and that has come up on suvery (as I knew it probably would). We've had lots of airbricks fitted but when it's really cold outside, there is condensation on the felt. There are no leaks in the roof. There's also apparently "a problem with the way the bay window was built" (house was built in 1936, we bought it 10 years ago and nothing related to the window came up when we had our survey done).
based on all this the surveyor has valued the house at 425, 70k below asking price, and buyer has (understandably, I suppose) pulled out. i'm honestly stunned and can't see how this could be accurate, especially as the external wall insulation was done by a prominent company that's still in business with hundreds of 5-star reviews, neighbours had exactly the same thing done at the same time and their house has since been bought/sold without any issues. i can't see how even with a whole new damp course, new vents and new windows we're getting to 70k of work?! and we've never had even a hint of damp in the house (i've lived in houses with damp issues and have always felt lucky that i didn't need to deal with it here). is it usual for surveyors to overestimate costs and problems, or are we screwed??!
