So I'm in the process of getting a garden office installed. It was put together two weeks ago, windows and doors have been in since last week and I'm currently waiting for the insulation and cladding to be done. Annoyed that it's not done yet, but also pleased because you can see things that would otherwise be hidden behind the cladding
So after a day of very persistent rainfall, I notice damp around the bottom of the uprights and some floor boards on one wall only (it's the weather facing wall and it did rain rather heavily). I've marked it out on one of the photos, it's the wall to the left. It looks like it's seeping in from underneath or behind, around the uprights and also part of the floor boards as can be seen in one of the photos. Difficult to pinpoint a source since there is vapour membrane inside. After the sun came out it dried really quickly.
I got in touch with the company today and can't make my mind up whether they're having me on or not. They are saying
My gut feeling is telling me that the explanation re "treatment draining" may not be...100% legitimate? ... but I'm by no means an expert so would be extremely grateful for some thoughts on
- whether the reason given for the "damp" sounds reasonable
- what other steps I can take other than potentially putting another coat of paint on to the weather facing wall, close all the knots with silicone and put a line of silicone just above the DPC to ensure no water is driven up....
I would really like to get this sorted before the insulation and cladding go on (and I won't be able to see it any more )...so really hoping for more rain in the next couple of days
Thank you for reading this and thanks in advance for any thoughts anybody might be able to share.

- weather proofing the building is customer responsibility through painting and attaching gutters
- I quote: "What you are experiencing is perfectly normal. This is the treatment draining from the uprights and just requires the building to be aired. Pressure Treatment in the timbers may take a while to dry fully"
- Joints or gaps should be sealed with sealant or mastic
