the landscaper goes to her house for the last 5 years on an hourly basis. I met her and she seemed evasive and defensive for no reason. I was helping my friend empty her shed of her junk and found that the floor needed to be replaced. When I spoke to the landscaper, she told me that her husband was contracted to do the job. After the job was done, I spoke to my friend and she told me she paid them 4000.00. I asked to see the receipt and it had one line item. Replace floor - 4000.00. I was told that he was there with a helper for 2 days.
I would ask for an itemized work order list. Hopefully on the list is a polythene vapor barrier weighted down with stone or concrete beneath the shed will provide a barrier to moisture and also prevent plant growth beneath the shed. And if insulation was installed between the floor joists depending on the future use of said shed.
If the owner is sharp at 90 years old, remember she gave authorization to do the work.
Is the contract with the landscaper ongoing, though? Don't spoil a good working relationship for the sake of it; but do use this as an opportunity to help your friend get rid of a parasite - provided, of course, that you have a better suggestion as to how she can look after her garden.
Is your friend likely to want you to ring and ask them to justify the labour charge? I'd be surprised if she wanted the trouble. Unless she really can't afford to, it's probably better to chalk this one up to experience and counsel her to get written estimates in advance in future.
idda still sawed the joists out and poured the floor. wood = bug food
I am curious, who is questioning the final cost? You or the owner? If the owner was initially fine with the cost, then it is a non-issue. I wouldn't put her through unwanted stress even if you think the cost was a bit high.
Good luck, realtor - just remember "discretion is the better part of valour..."
