Before you hire an outdoor services company in Central Pennsylvania, ask whether it is registered under state law, properly insured, experienced with your specific project, and willing to put everything in writing. The most important questions cover registration and insurance, experience and credentials, references and past work, written estimates and contracts, warranties, who actually does the work, and the payment schedule. Good companies answer all of these clearly and without pressure. This guide lists the exact questions to ask, explains why each one protects you, and shows what a solid answer sounds like, so you can hire with confidence and steer clear of the scams that leave homeowners with unfinished work and lost money.
Why the Right Questions Matter Before You Hire
Hiring an outdoor services company is a real financial decision. Irrigation systems, outdoor lighting, and yard work run underground wires, dig trenches, and touch your water and power, so the wrong crew can leave you with property damage on top of a bill.
The U.S. Federal Trade Commission warns that home improvement scammers may promise the work, then do shoddy jobs, damage your home, overcharge you, or take your money and disappear. Asking a short set of clear questions up front is the simplest way to tell an established local company from a fly-by-night operator. Companies like Evergreen Contracting & Irrigation welcome these questions, because clear answers are part of how a trustworthy business earns your work.
Here are the questions to ask, and what a strong answer looks like.
Is Your Company Registered and Insured in Pennsylvania
Start here, because this question is backed by state law. Pennsylvania passed the Home Improvement Consumer Protection Act in 2008. According to the Pennsylvania Office of Attorney General, any contractor who performs at least 5,000 dollars of home improvement work per year must register with the Attorney General’s Office and receive a Home Improvement Contractor registration number.
That number should appear on the company’s contracts and estimates. The Office of Attorney General also runs a free Home Improvement Contractor verification tool, so you can confirm a registration before you sign anything. Keep in mind that registration is a consumer-protection filing, not a state endorsement of quality, so it is a floor and not a finish line.
Insurance is the other half of this question. The Attorney General’s Office requires registered contractors to carry at least 50,000 dollars in personal injury liability coverage and 50,000 dollars in property damage coverage. Ask for a certificate of insurance, and confirm the company also carries workers’ compensation for its crew. If a worker is hurt on your property and the company is uninsured, you could be held responsible.

A strong answer sounds like this: the company gives you its registration number, provides proof of insurance without hesitation, and confirms workers’ compensation for every crew member.
How Long Have You Been in Business and What Credentials Do You Hold
Experience shows up in the finished work. Ask how many years the company has operated in the Central PA area, and who will actually be on your property. A long local track record usually means the crew has handled the soil, slopes, and freeze cycles common to this region.
Credentials matter too, especially for irrigation. The U.S. Environmental Protection Agency’s WaterSense program certifies irrigation professionals through labeled certification programs that focus on water-efficient design and installation. The EPA reports that when homeowners hire certified irrigation professionals for regular maintenance, each household can cut irrigation water use by about 15 percent, or nearly 9,000 gallons a year. Manufacturer training on the brands a company installs is another good sign of a serious operation.
A strong answer sounds like this: the company shares its years in business, names the people who will do the work, and points to certifications or manufacturer training that back up its claims. As a locally owned and family operated business serving Dauphin County since 2001, with more than 60 years of combined experience, Evergreen Contracting & Irrigation is a useful benchmark for what real local experience looks like.
Do You Specialize in the Services I Need
Some companies mow lawns and little else. Others design and install full irrigation and outdoor lighting systems. Ask the company to describe exactly what it does best, and be cautious of any operation that claims to do everything at a price that seems too low to be real.
If your project spans more than one service, hiring one company that handles both saves you from coordinating separate crews and untangling who is responsible when something goes wrong. A company that offers complete irrigation services and professional outdoor lighting installation under one roof can plan both systems together, share trenches where code allows, and keep the work on one accountable team.
Can You Provide References and Examples of Past Work
Any company can call itself the best. References and photos prove it. Ask for a few recent customers you can contact, and for examples of projects similar to yours.
Then do your own homework. The FTC recommends reading customer reviews with a critical eye and searching the company name along with words like scam, review, or complaint. Trusted rating sites and a company’s own customer reviews page fill in the picture. A company proud of its work will share references and a portfolio without stalling.
Will I Get a Written Estimate and Contract
Get everything in writing, every time. The FTC advises collecting multiple written estimates and warns against automatically choosing the lowest bidder, since a price far below the others often means cheaper materials, inexperienced labor, or missing tasks. Ask each bidder to quote the same scope so you are comparing like for like.
A written estimate should spell out the work to be done, the materials, the start and completion dates, and the total price. Pennsylvania law goes further. The Home Improvement Consumer Protection Act requires a written contract for any home improvement job over 500 dollars, and that contract should include the contractor’s name, address, and registration number.
A strong answer sounds like this: the company provides a detailed written estimate for free and puts the full job in a clear contract before any work begins.
What Warranties Do You Offer
Warranties tell you how much a company stands behind its work. Ask two questions here. First, what warranty covers the labor and installation. Second, what manufacturer warranties come with the parts, such as controllers, valves, and light fixtures.
Get the terms in writing and keep a copy. A company offering a multi-year warranty on new installations, plus manufacturer coverage on components, is signaling that it expects the work to last. For reference, Evergreen Contracting & Irrigation backs new installations with a two-year warranty and offers manufacturer warranties on parts.
Who Does the Work and How Is Payment Handled
Ask whether the company uses its own employees or subcontractors. In Pennsylvania, subcontractors who perform home improvements must also be registered under the Home Improvement Consumer Protection Act, so confirm that anyone stepping onto your property is covered and insured.
Payment terms are a major safety signal. The FTC lists several classic scam moves: asking you to pay for everything up front, accepting only cash, claiming to have materials left over from another job, pressuring you for an immediate decision, or steering you to a specific lender. Consumer protection offices generally advise against paying more than one third of the cost up front. A reasonable deposit with the balance tied to progress or completion is normal. A demand for full cash payment before work starts is not.

Do You Handle Permits, Utility Marking, and Seasonal Service
A professional company manages the details that keep you safe and legal. Ask whether the company handles any needed permits and, importantly, whether it calls 811 before digging. Pennsylvania law requires contacting the Pennsylvania One Call System, reached by dialing 811, so buried utility lines can be marked before a shovel goes in the ground. A company that expects you to handle this yourself is one to avoid.
Also ask about ongoing service. Central PA winters demand that irrigation systems be drained and winterized each fall to prevent frozen, cracked pipes, with a startup in spring. A company that offers seasonal inspections and maintenance plans will help your system last for years rather than leaving you on your own after installation.
Red Flags to Watch For
Keep this short list in mind while you interview companies. According to the FTC, be cautious of a contractor who:
- Shows up uninvited or claims to have leftover materials from a nearby job
- Pressures you to sign or pay right away
- Wants full payment up front or accepts only cash
- Refuses to provide a written contract
- Cannot show proof of registration or insurance
- Asks you to pull the building permits or arrange your own financing through their lender
Any one of these is a reason to slow down. Two or more is a reason to walk away.
A Quick Checklist of Questions to Ask
