Don’t Sign Until You’ve Asked These
Thinking about adding a pond, but not sure who to trust with your backyard? Worried you’ll pick the wrong builder and end up with a leak, dead fish, or a rebuild a year later?
In this post, you’ll learn the exact questions to ask a pond contractor before hiring, covering licensing, experience, materials, your contract, timelines, and what happens after the build.
By the end, you’ll know how to spot a trustworthy contractor and protect your pond construction investment before any work begins.
Here in the East Bay, California Aqua Pros has spent decades building ponds and fixing ones that were done wrong, so we know which questions separate a good contractor from a costly mistake.
The Key Questions to Ask a Pond Contractor Before Hiring
Before you hire a pond contractor, ask these 7 key questions:
- Are you licensed, bonded, and insured?
- How long have you been building ponds, and are you Aquascape certified?
- Can I see your past work and talk to past clients?
- Will you use a liner or concrete?
- What does your design process and written proposal include?
- What’s your timeline, and how do you handle surprises?
- What happens after the pond is built?
Each answer tells you whether you’re dealing with a true pond specialist or a general contractor guessing their way through a job.
1. Are You Licensed, Bonded, and Insured?
This is the first question, and the answer should be easy for any real professional to give.
A licensed contractor has met state standards and can be held to them.
Insurance protects you if someone gets hurt on your property or if something gets damaged during the build.
We hold a California C-53 Swimming Pool Contractor License #692180, and we’re fully licensed, bonded, and insured.
That C-53 license carries the same bonding standards as a general contractor license, so we’re equipped to handle complex builds involving slopes, structures, and pools, not just the pond itself.
2. How Long Have You Been Building Ponds, and Are You Aquascape Certified?
Experience matters more with ponds than almost any other backyard project.
A pond is a living ecosystem, so a contractor who builds one or two a year is still learning on your dime.
Certification is one of the few ways to verify real training in an industry that isn’t tightly regulated.
We started building ponds in 1993, we’ve completed over 600 of them, and we’re a family-owned, Master-Certified Aquascape Contractor, one of only a small group nationwide at that level.
That means we don’t guess. We build using a proven system we’ve used for over 30 years.
3. Can I See Your Past Work and Talk to Past Clients?
A real portfolio tells you more than any sales pitch.
You want to see a range of finished, similar projects, not just one lucky photo. You also want them to be able to refer you to previous clients so you can gain first-hand insight into their business.
When you look at a contractor’s past work, check for these signs of quality:
- Natural rock placement that looks like it belongs, not piled up.
- Clear, healthy water in their finished ponds.
- A variety of styles, which shows they can match your vision.
- Real client references you can actually call.
We’re happy to share projects we’ve done and connect you with past clients during your consultation, and you can browse the ponds we’ve built across Brentwood, Walnut Creek, Livermore, and the rest of the East Bay.
4. Will You Use a Liner or Concrete?
This question quietly reveals how much a contractor actually understands about ponds.
The material under your pond decides whether it lasts decades or starts cracking and leaking.
We build both ponds and pools, which gives us hands-on experience with liners and concrete, so our answer comes from real knowledge, not habit.
For ponds, we build only with a 45 mil EPDM liner.
Concrete ponds have to be built like swimming pools, with steel reinforcement and gunite, or they crack as the ground shifts, and that makes them far more expensive for no added benefit.
A flexible liner moves with your soil and is simpler to repair, which is why we trust it for every pond we install.
5. What Does Your Design Process and Written Proposal Include?
A clear process is a sign you’re working with professionals, not someone who wants to start digging before there’s a plan.
Be cautious of anyone who won’t put the details in writing.
Our process follows the same steps every time:
- A phone consultation to discuss your goals and make sure we’re the right fit.
- A personal on-site visit where your designer sketches ideas, with the consultation fee credited toward your project.
- An itemized proposal that lays out costs, timelines, and project details.
- Material selection and final design, then contract signing and scheduling.
You’ll know exactly what’s included and what to expect before you ever commit.
6. What’s Your Timeline, and How Do You Handle Surprises?
A good contractor can give you a realistic timeline and a calm answer about what happens when something unexpected comes up.
Most of our ponds take between 4 days and 3 weeks to build, with the average landing around 1 to 1.5 weeks.
Larger projects that coordinate with other trades can run longer, and we’ll tell you that upfront instead of surprising you later.
We also plan ahead by pre-plumbing for future features during the build, so adding a waterfall or an upgrade down the road doesn’t mean tearing concrete apart.
7. What Happens After the Pond Is Built?
The right contractor sticks around after the last rock is placed.
Ask about warranties, follow-up, and ongoing care before you sign.
We include a one-year craftsmanship warranty, and some products come with extended warranties we’ll help you set up.
After your pond is finished, your designer visits within a month to make sure you’re happy, and we offer year-round maintenance plans if you’d rather leave the upkeep to us.
A pond runs 24/7 to keep its ecosystem healthy, so having a team you can call long-term matters.

Red Flags to Watch For
After 30 years, we can tell you the warning signs are usually obvious once you know to look.
Roughly half of our work is repairing or rebuilding ponds that other contractors built wrong, so we’ve seen what cutting corners leads to.
Watch out for these red flags while you compare contractors:
- A bid that’s far lower than everyone else’s, which usually means corners will be cut.
- Pressure to sign fast before you’ve had time to think.
- A vague, verbal-only estimate instead of a written proposal.
- No license, no insurance, or hesitation to show proof.
- No real portfolio or references to back up their claims.
The cheapest option often turns into the most expensive one once the leaks and headaches start.
