What you describe is common with housebuilders especially at Persimmon Homes.
This is why they have just a three star rating by their own customers!
Most builders might be more accommodating when you first move in, so you give them a positive response in the HBF survey, but after 10 weeks or so, after doing the easy cosmetic snags they don't help at all.
Not all warranties are the same, which is why I advise all new home buyers to walk away if there is not an NHBC warranty available. LABC is the same as Premier Guarantee, both are administered by MD Insurance Services! Many buyers have had difficulty claiming.
The NHBC is far from perfect but in my opinion, streets ahead of any other warranty.
