Before you accept a renovation quote, find out what the price may not be telling you.
Designed for substantial, architect-led residential renovations.
The plans can look complete.A builder’s price can look fixed.Important scope, allowances, exclusions and assumptions can still be unresolved.
OverSea’s Renovation Quote X-Ray independently reviews your quote against the plans and your expectations so you know what to confirm before committing.
Renovation Quote X-Ray
An independent, homeowner-side analysis before you accept a builder’s quote.We examine your builder’s quote alongside the available plans, specifications and project information to identify:
work that appears missing or unclear
inconsistencies between the quote and the plans
exclusions, assumptions and provisional allowances
selections or decisions being deferred until construction
potential exposure to variations, delays or misunderstanding
questions that should be answered in writing before you proceed
This is not a cost estimate or a line-by-line check of every quantity. It's a structured review of whether the plans and supporting documents describe the renovation you believe you are buying.

Who's it for
The Renovation Quote X-Ray is designed for homeowners with architect-prepared plans and builder pricing for a substantial residential renovation who:
have received a builder’s quote or proposal
have plans, specifications or a written project brief
are approaching a major financial or contractual commitment
want an independent perspective before proceeding
are concerned that the documents may not tell the whole story
It's particularly suited to substantial residential renovations where unclear scope can become expensive once construction begins.It is not a building inspection, quantity survey, technical compliance assessment or legal review of the building contract.It's not intended for stand-alone kitchen or bathroom upgrades, cosmetic refreshes, maintenance work or minor renovations.
