Your outdoor project is a real investment — and the contractor you choose matters more than any single material. Here are the 10 questions that separate a builder you can trust from one you'll regret, plus the red flags to walk away from.
1. How long have you been building, and in this area?
Experience shows in the details. Ask how long they've been in business and whether they work regularly in your area — a local builder knows the soil, the code, and the climate. (For reference, Hearth & Hammer has served York County since 2012, with nearly 20 years of construction experience.)
2. Are you insured?
Ask for proof of liability insurance so you're protected if something goes wrong on your property. A professional will have it and won't hesitate to share it.
3. Can I see photos and references from past work?
Any established builder should have a portfolio of completed projects and past customers willing to vouch for them. Look for work similar to what you want built.
4. Will I get a written, itemized estimate?
You should see materials, site prep, drainage, labor and cleanup broken out — not just one lump number. An itemized estimate lets you compare bids fairly and understand what you're paying for.
5. Who actually does the work?
Ask whether their own crew builds the project or whether it's handed to subcontractors — and who supervises. Consistent, accountable crews tend to produce more consistent results.
6. What's the timeline?
A good contractor gives you a realistic start date and duration, and is honest about how weather can affect it. Vague or wildly optimistic timelines are a warning sign.
7. How do you handle permits and code?
Raised decks and taller retaining walls often need permits. Your contractor should know local requirements and handle them, building to code — not leave it on you or skip it.

For patios and walls especially, the hidden work — a compacted base, gravel backfill, proper drainage — is what makes a project last. A builder who talks about this cares about longevity, not just the surface.
9. What happens if there's a problem?
Ask how they handle issues that come up during or after the build, and whether they stand behind their work. You want a straight answer, not a shrug.
10. Does the payment schedule make sense?
A reasonable deposit to schedule and order materials is normal. Be wary of anyone demanding full payment up front.
Red flags to walk away from
- No written estimate or contract
- Demands full payment before work starts, or cash only
- Can't provide proof of insurance or any references
- Pressure tactics or a "today only" price
- A bid far below everyone else's (something's being left out)
The bottom line
The best contractor isn't always the cheapest — it's the one who communicates clearly, shows their work, and builds it to last. Ask these questions, trust your gut, and you'll end up with a project you love.
