Pennsylvania law puts specific requirements on the paperwork you receive from an irrigation or outdoor lighting contractor. Any home improvement contract over $500 must be in writing, must carry the contractor’s state registration number, and must include notice of your right to cancel within three business days of signing. A contract missing required terms is unenforceable against you. And as of an April 2026 Pennsylvania Supreme Court decision, you can exercise that cancellation right by phone or in person, not only in writing. Warranties are separate from all of that and usually come in two layers, a manufacturer warranty on parts and a contractor warranty on labor, with different lengths and different exclusions.
This guide covers what the law requires, how to compare estimates that are not written the same way, and what warranty terms actually mean.
What an Estimate, a Proposal, and a Contract Actually Are
These words get used interchangeably and they are not the same thing.
An estimate is a projection of cost. It carries no obligation on either side. A contractor can revise it.
A proposal describes scope and price and is generally an offer. It becomes binding when you accept it, which is why a proposal you sign can function as a contract.
A contract is the binding agreement, and in Pennsylvania it has to satisfy statutory requirements to be enforceable against you.
The practical point is that signing a document labeled proposal or estimate can still create a contract. Read what you sign rather than what it is called. Anything from Evergreen Contracting & Irrigation or any other contractor should be evaluated on its contents, not its heading.

What Pennsylvania Law Requires in the Contract
The Home Improvement Consumer Protection Act, Act 132 of 2008, governs home improvement work over $500 on private residences. It does not cover commercial property or new home construction.
|
Requirement |
What it means |
| Written and legible |
An oral agreement is not a compliant home improvement contract |
|
Contractor registration number |
Required on advertisements, contracts, estimates, and proposals |
| Notice of the right to rescind |
Must state you may cancel within three business days of signing, without penalty |
|
A completed copy at signing |
The contractor must deliver a full copy, free of charge, when the contract is executed |
| Arbitration clause in capital letters |
If the contract includes arbitration, the clause text must be capitalized or a court may deem it void |
The law also lists clauses that make a contract voidable by you. Among them: waiving federal, state, or local health, life, safety, or building code requirements; confession of judgment; waiving your right to a jury trial; wage assignment; agreeing not to assert any claim or defense arising out of the contract; awarding the contractor attorney fees and costs; relieving the contractor of liability for its conduct in collecting payments; and waiving any right the act provides.
Two consequences worth understanding:
A noncompliant contract is unenforceable against you. If it fails to contain required terms, Pennsylvania courts treat it as invalid against the homeowner. That protection runs one direction, in your favor.
You are not required to prepay before signing. A contractor asking for money before a written contract exists is asking for something the law does not contemplate.
Your Three Business Day Right to Cancel
This is the provision most homeowners never learn about, and it recently got stronger.
The statute gives you three business days from the date of signing to rescind a home improvement contract without penalty, regardless of where the contract was signed. The contract itself must tell you this.
For years, many contractors required written cancellation, borrowing that requirement from Pennsylvania’s broader consumer protection law. On April 30, 2026, the Pennsylvania Supreme Court settled it. In the Office of Attorney General’s case against Gillece Services, the Court held that the home improvement statute, being the more specific and more recently enacted law, governs these contracts, and that consumers may cancel within the three day window by giving actual notice in any form.
According to the Attorney General’s office, the practical effect is that a cancellation delivered by phone, in person, or in writing all count, provided the contractor has actual notice. The case arose after homeowners tried to cancel verbally and the company proceeded with work anyway.
Three practical notes:
- Business days, not calendar days. A Friday signing generally runs into the following Wednesday.
- Put it in writing anyway. The ruling means writing is not required, and a written record is still the easiest way to prove the date and content of your cancellation. A concurring justice in that case made the same point.
- Emergency situations are treated differently under the statute.
How to Compare Estimates That Are Not Comparable
This is the practical problem. Three quotes arrive and none of them describe the same job.
Common reasons two irrigation quotes differ by a wide margin:
- Different zone counts. One contractor measured available flow, another guessed. More zones cost more and often reflect better design, not padding.
- Different pipe specifications. Class 200 PVC and Schedule 40 are not the same product, and neither is cheap poly against Class 160.
- Different head quality. Pressure-regulating bodies cost more per head and save water for twenty years.
- Backflow included or excluded. Sometimes the assembly and the plumbing permit sit outside the quoted price.
- Restoration included or excluded. Trench repair and reseeding are real costs someone is paying.
- Winterization included or not for the first season.
To normalize them, build a comparison of your own with one row per item: zone count, head models and quantity, whether bodies are pressure regulating, pipe type and class for mainline and laterals separately, controller model, backflow device and who obtains the permit, sleeving, trench restoration, documentation provided, and warranty terms.
Then ask each contractor to fill the gaps. The one who cannot answer the pipe class question or explain the zone count has told you something useful. A properly scoped irrigation system installation proposal contains these details already, because they are the decisions that determine whether the system works.
Price differences that survive normalization are real. Price differences that disappear once you compare like for like were never differences at all.
What a Complete Irrigation Estimate Should Specify
If any of these are missing, ask.
- Measured static pressure and available flow at the property
- Zone count, with the reasoning tied to those measurements
- Head and nozzle models by zone, and whether bodies are pressure regulating
- Pipe type and pressure class, listed separately for mainline and laterals
- Trench depths for mainline and laterals
- Sleeve locations and sizes for any hard surface crossing
- Backflow device type, who supplies it, and who obtains any permit
- Controller model and number of stations
- Who calls PA One Call
- Trench restoration and seeding
- Documentation delivered at completion
- Warranty on parts and labor, stated separately
- Payment schedule
What a Complete Lighting Estimate Should Specify
Lighting quotes vary even more widely than irrigation, because fixture quality spans an enormous range.
- Fixture count, model, and material, since cast brass and stamped aluminum are very different products
- Lamp or integrated diode type and color temperature
- Transformer size, model, and location
- Wire gauge and run lengths, which determine voltage drop at the far fixtures
- How the transformer is powered, and whether an electrician is involved
- Control method, whether timer, photocell, or app based
- Whether trenching is shared with irrigation work
- Warranty on fixtures against warranty on labor
Voltage drop is the item to watch. A run that is too long on wire that is too thin delivers less voltage to the last fixture, which shows up as dim or color-shifted light. Any outdoor lighting design and installation proposal that lists fixture counts but no wire gauge or transformer sizing is leaving out the part that determines whether the system performs.
The Warranty Layers and How They Interact
You are usually covered by two separate warranties, and they behave differently.
|
Layer |
What it covers | Typical length | Key catch |
| Manufacturer warranty | Defects in the component itself | 2 to 5 years, varies by product |
Often runs from date of manufacture, not installation |
|
Contractor labor warranty |
The installer’s workmanship | Varies widely, ask |
Set by contract, not by law |
The date of manufacture point matters. Hunter’s statement of warranty specifies that its coverage period runs from the original date of manufacture. A rotor that sat in a distributor’s warehouse for a year arrives with part of its warranty already spent.
The two layers also cover different failures. A valve that fails because the diaphragm was defective is a manufacturer issue. A valve that fails because it was installed backward is a labor issue. In practice, the manufacturer covers the part and somebody still has to locate the fault, dig, and install the replacement. On a repair where diagnosis takes longer than the swap, a free part is a small portion of the bill.
That is why the contractor’s labor warranty matters more than the box’s warranty in the first years. Ask for it in writing, ask what it covers, and ask whether diagnostic time is included. Those questions are much easier to ask before signing than during an irrigation service and repair call two years later.
What Warranties Usually Exclude
Read the exclusions, because they are where most disputes live.
- Freeze damage. The single largest exclusion in this climate. If the system was not winterized, or was winterized by someone else, expect the claim to be denied.
- Acts of God. Rain Bird’s professional warranty states plainly that failures from acts of God, including lightning and flooding, are not covered. Summer storms here kill controllers regularly.
- Damage by others. Mower strikes, aeration, fence installation, and work by other trades.
- Normal wear. Nozzle scale, worn seals, and gradual coverage loss.
- Water quality. Mineral scale from hard water and sediment from well supply.
- Improper operation. Running the system in freezing weather, or modifying the schedule in ways that damage components.
The freeze exclusion deserves attention, since it interacts with your maintenance choices. Keeping documented, scheduled seasonal irrigation services creates a record that the system was drained correctly and by whom, which is exactly what a warranty claim on spring damage will turn on.
Warranty Conditions That Can Void Coverage
Separate from exclusions, some warranties impose obligations on you.
- Annual maintenance by the installer. Some labor warranties require that the original contractor perform the winterization and start-up. Reasonable, and worth knowing before you shop the blowout on price.
- Registration. Certain manufacturer warranties require product registration within a set window.
- No unauthorized modification. Adding zones or swapping components yourself can void the labor warranty on the affected work.
- Timely notice. Many contracts require you to report a problem within a stated period.
- Proof of professional winterization in cold climates.
That third item catches people. If you plan to add a drip zone or change heads yourself later, ask how that affects existing coverage first. Having the same contractor handle later irrigation upgrades usually keeps the warranty intact where doing it yourself would not.
Payment Terms and Deposits
Three things to check on the payment schedule.
The deposit. Attorney General guidance describes an appropriate ceiling of roughly one third of the contract price, or one third plus the cost of special order materials. A demand well above that is a warning sign.
No prepayment before signing. You are not required to pay anything before a written contract exists.
Progress payments tied to milestones. Payments should attach to completed stages rather than dates on a calendar. Final payment should follow completion and your walkthrough, not precede it.
Also confirm how change orders are handled. Discovering rock, unmarked utilities, or an unexpected slope can legitimately change scope. What should not happen is a verbal change followed by a larger invoice. Change orders belong in writing, signed, before the work happens.
Final Thoughts
Pennsylvania gives you real protections on this paperwork. Any home improvement contract over $500 must be written, must carry the contractor’s registration number, must include notice of your three business day cancellation right, and must be handed to you in complete form at signing. A contract missing required terms is unenforceable against you, and one containing prohibited clauses is voidable.
Since April 2026, that cancellation right can be exercised by phone or in person as well as in writing, following the Pennsylvania Supreme Court’s decision in the Attorney General’s case against Gillece Services. Put it in writing anyway, because a record is easier than a memory.
On warranties, expect two layers with different rules. Manufacturer coverage on parts, frequently running from date of manufacture rather than installation, and contractor coverage on labor, set entirely by your contract. Read the exclusions, and treat freeze damage as the one that matters most here.
When comparing quotes, normalize them line by line before comparing prices. Zone count, pipe class, whether sprinkler bodies regulate pressure, and whether restoration is included will explain most of the gap.
For a proposal you can actually evaluate, ask about sprinkler system installation in Central Pennsylvania and request measured pressure and flow, zone count with reasoning, component models by zone, and parts and labor warranty terms stated separately. A contractor willing to put that in writing has given you something you can hold them to.
