Construction advice

Construction advice for homeowners, not for the trade.

Everything here is written for the person paying for the work. Start with builder quotes, then contracts, then the changes and payments that follow once work begins.

Quotes

Comparing builder quotes

Why totals mislead, what a complete quote contains, and how to line quotes up fairly.

Contracts

Agreeing terms before work starts

Variations

Changes and extra costs

What a fair variation looks like, and how to approve one without losing control of the budget.

Snagging

Finishing well

What to check before the final payment, and how to write a snagging list a builder will act on.

Quotes

Three quotes, three different projects
