What is the difference between a quote and an estimate?

A quote is a fixed price offer that becomes binding when accepted. An estimate is an indication of likely costs that can change. Always ask for a quote rather than an estimate when you are ready to proceed.

How long should a contractor quote be valid?

Standard validity is 30 days. This gives you time to compare options without prices changing. Be wary of very short validity periods (7 days) as this may be a pressure tactic.

Should I always accept the cheapest quote?

No. Compare quotes on scope and detail, not just price. The cheapest quote may exclude items others include, use lower quality materials, or come from less reliable contractors. Mid range quotes from verified contractors often represent best value.

What if something is not mentioned in the quote?

If work is not explicitly included in the quote, assume it is excluded. Ask the contractor to clarify in writing before signing. Get any verbal agreements added to the written quote.
