## Ask these five questions before you hire

Prices vary with the job. The fastest way to a fair number is to ask every business the same questions and compare the answers.

1.

### What does a typical project cost?

Prices on websites are rare and rarely comparable. We ask for the range clients actually paid in the last 12 months, and what that range includes.

2.

### How long does a typical project take?

A schedule tells you how a business plans. We ask for the time from signed contract to finished job, and what most often makes it late.

3.

### What should homeowners prepare before asking for a quote?

A better first conversation gets you a firmer price. We ask what saves the most time and money before anyone visits.

4.

### What kind of work do you specialize in?

Most businesses say they do everything. We ask what they do most and best, and what they turn down.

5.

### What expensive mistake do homeowners commonly make?

Businesses see the same mistakes again and again. We ask for the one that costs their clients the most.
