A good contractor listens, explains, shows you real details and puts the scope in writing. Here is what to ask and what to look for.

Ask how they build the base

The base is where patios succeed or fail. Ask how deep they excavate, what material they use and how they compact it. A thoughtful answer tells you a lot.

Ask also about drainage, edge restraints and how they handle slopes and tree roots.

Look for clear scope and drawings

A good proposal lists the area, the materials, the features, the base, the drainage and what is not included. Drawings or a layout sketch show you what you are getting.

Be wary of vague proposals that leave out base work or drainage.

Compare bids fairly

Two bids that look different may include different base depths, different materials or different drainage. Put them side by side and ask about each difference.

The lowest bid is not always the best value if it leaves out the parts you cannot see.

Check how they communicate

You will be working together for weeks. Notice whether they return calls, explain choices in plain words and give you one clear point of contact.
