How to read a contractor quote (and the five things missing from most of them)
Homeowners are routinely told to get three quotes, and then given no guidance on how to compare them. The result is that most people pick on price, discover the cheapest quote excluded something important, and conclude that contractors are untrustworthy. Usually they were just reading the wrong things.
Compare scope before you compare price
A quote is a description of work with a number attached. If two quotes describe different work, the numbers are not comparable and no amount of staring at them will make them so. Read the scope first, in detail, and write down the differences. Does one include tear-off and disposal and the other an overlay? Does one include permits? Does one include repairing the stucco it will damage?
The five things usually missing
- Allowances for the unknown. Any job that opens up a structure has unknowns — rotten sheathing, unsuitable soil, undersized wiring. A good quote names them and prices them per unit in advance. A quote that stays silent has not removed the risk, only the discussion of it.
- Exclusions, stated explicitly. What is not in this price? Landscaping repair, haul-away, permit fees, the electrical panel upgrade? The absence of an exclusions list is not the same as nothing being excluded.
- A payment schedule tied to progress. Payments should follow milestones, not the calendar. In California a contractor may not ask for a deposit greater than $1,000 or 10% of the contract price, whichever is less. A large up-front demand is both a red flag and, frequently, a violation.
- Two separate warranties. The manufacturer warrants the material; the contractor warrants the workmanship. They have different lengths and different exclusions, and most failures in the first few years are workmanship. Get both in writing.
- Who pulls the permit. If the contractor asks you to pull it as an owner-builder, understand what you are agreeing to: you become responsible for the work, and you may lose recourse if it goes wrong.
Verify the licence, properly
In California, check the licence number on the CSLB website. Confirm it is active, that the classification matches the work, and that the bond and workers' compensation coverage are current. This takes two minutes and is the single highest-value thing you can do before signing. Ask for a certificate of insurance naming you, and confirm it directly with the insurer rather than accepting a photocopy.
Red flags worth walking away from
A price that expires today. A large cash deposit. Pressure to sign at the kitchen table on the first visit. An unsolicited door knock after a storm. A reluctance to put the scope in writing. Any of these on their own may be nothing; two together is a pattern.
The cheapest quote is not automatically wrong
It is worth saying plainly: a lower price sometimes just reflects lower overheads, a crew already working nearby, or a contractor who wants the job. That is exactly why block scheduling lowers prices legitimately. What matters is whether the low quote covers the same scope with the same warranty from a licensed, insured contractor. If it does, it is simply a better price.
