We provide a service where we can produce and manage your snagging but more importantly you can find lots of inormtaion on our website on the legal requirements of the builder to rectify snagging
You should always complete a snagging inspection before completion and include the list with the documents submitted at The Notary
Also if you look at the articles published, which is on the right of the forum you will see one headed Most Commonly Asked Questions on Completions and Snagging Inspections which again answers most of your queries
There is no legal obligation for the builder to rectify the defects untill after you have completed and you have very few grounds to refuse to complete based on snagging defects
The grounds are if the property does not meet specification, is not complete, or deoes nit have a Certificate of Habitation
We have sample reports and guides available if you send me a PM
