Should I guarantee my work on my website?

September 4, 2026 · 7 min read

Yes, in most cases - but a specific, bounded promise beats a vague one every time. "100% satisfaction guaranteed" with no scope or time limit is the most-copied sentence in the industry, and homeowners have learned to read right past it. "Two-year workmanship warranty on all installation labor" is a sentence you can actually stand behind, and it is more convincing for being smaller and more specific.

Here is the real tension owners feel about this, the three kinds of guarantee worth considering, the wording that backfires, and the one phone call worth making before you publish anything.

Why this is harder to decide than it looks

Two things are true at once. A guarantee is a genuine trust signal - it tells a homeowner comparing three sites at nine at night that you are confident enough in your own work to put a promise behind it, which matters even more to someone who has been burned by a shared-lead platform and does not trust anyone's word right now. But a guarantee is also a real commitment. Word it too loosely and you have promised free redo work with no limit, on a job you have not even started yet. Word it too cautiously - or skip it entirely because the whole idea feels risky - and you look like every other site that says nothing, which is its own quiet cost.

The fix is not "guarantee more" or "guarantee less." It is "guarantee something specific enough that you would actually honor it without a second thought."

The three kinds worth knowing apart

Different trades break in different ways, so the right guarantee depends on how your work actually fails, not on which phrase sounds the biggest.

1. Workmanship warranty - for one-time, physical jobs

This covers your labor for a set period after a project: if something fails because of how it was installed, not because of normal wear, you fix it free within that window. It fits roofing, painting, remodeling, decks, concrete, and fencing - work where a bad install shows up months or years later, not the same afternoon. A common, defensible version: "Two-year workmanship warranty on all installation labor." Longer is not automatically better - a 25-year warranty on a two-person crew's labor is the kind of number that makes an experienced homeowner suspicious rather than confident.

2. Satisfaction guarantee - for recurring or lower-stakes work

This is a shorter-fuse promise that fits cleaning, lawn care, pest control, and small handyman jobs - work where the fix is "come back and redo it right," not a multi-year commitment. Something like: "If you're not happy with a visit, tell us within 48 hours and we'll come back and make it right at no charge." A time limit and a clear action (redo, not refund) keep this honest and keep you from accidentally promising an open-ended money-back policy you never meant to offer.

3. Manufacturer warranty - not actually yours to give

If you install HVAC systems, water heaters, windows, or anything with branded parts, those parts usually carry their own manufacturer warranty, separate from your labor - and some require the homeowner or installer to register the unit within a deadline to activate it at all. Say both, clearly separated: "10-year manufacturer parts warranty (registration required within 60 days) plus our 2-year labor warranty." The moment you blur the two into one guarantee, you have promised something a parts manufacturer controls, not you.

The wording that backfires

• No time limit at all. "Guaranteed for life" or "guaranteed forever" sounds generous until a customer calls about a job from six years ago and you have to decide, on the spot, whether "forever" really meant forever.
• No scope. "100% satisfaction guaranteed" answers nothing - satisfied with what, measured how, fixed by doing what? A homeowner cannot picture what actually happens if something goes wrong, so the phrase does less work than a plain sentence that spells it out.
• Copied from a franchise you cannot match. A national chain can absorb the cost of an occasional full refund across thousands of jobs. A two-truck operation copying that same "money-back guarantee, no questions asked" wording is promising something one bad month could actually cost real money to keep.
• Dollar amounts you have not checked with anyone. "We guarantee to cover up to $5,000 in damages" is no longer marketing copy - it is a promise your insurance policy either backs up or does not, and you want to know which before it is on your homepage, not after a claim.

The one call worth making first

This is not a suggestion to hire a lawyer before you write a sentence about your own work - most owners never need one for this. But if your guarantee mentions a specific dollar figure, covers damage to a customer's property, or promises anything beyond redoing your own labor, a short call to your insurance agent is worth ten minutes: ask whether what you are about to publish is something your policy actually supports, or something you would be covering personally if it were ever called in. For a plain workmanship or satisfaction guarantee with no dollar figure attached, this step usually is not necessary - it is the specific-dollar-amount and property-damage promises that are worth the call.

Where it goes on the page

A guarantee rarely earns the hero section - that space is for what you do and where you work. It belongs as one clear line in a trust section alongside your other credibility signals: license number, insurance, years in business, and reviews. A short "Why Choose Us" block with four or five lines - licensed and insured, a specific workmanship warranty, real reviews, a number you actually answer - does more than any one of those signals standing alone. See do I have to put my license number on my website and how do you get customers when you have no reviews yet for the rest of that trust-signal set.

Where RunCabin fits

Most owners do not land on the exact right wording the first time - you might start cautious with a shorter warranty window while you are new, then extend it once you have a real track record behind you, or tighten it after a job you wish you had scoped differently. On a RunCabin site that is a sentence, not a project: ask "add a line under Why Choose Us about our 2-year workmanship warranty" and it is live in a couple of minutes, in plain English, with no ticket and no designer to wait on.
