After 26 years fabricating and installing signs across Essex County, I keep seeing the same five mistakes on repeat, made by smart business owners who simply have not had to think about signage before. None of these are complicated to avoid once you know to look for them. This is the list I wish every new client read before they called a sign shop, mine or anyone else’s.
Mistake 1: Choosing a sign before checking the permit
The single most common mistake I see is a business owner falling in love with a design, sometimes even paying a deposit, before anyone checks what the local sign ordinance actually allows. Every municipality we serve, from Montclair to Nutley to Newark, has its own rules on square footage, illumination, setback, and in some cases historic district overlays that restrict color and material choices entirely.
I have had to tell clients that the sign they already picked out cannot go up as designed, and it is a conversation nobody enjoys. The fix is simple: pull the local zoning code for signage before finalizing a design, not after. A shop that skips this step to close the sale faster is setting you up for a redesign, a fine, or a stop-work order down the line. I have written in more detail about what a skipped permit actually costs in fines and rework.
Mistake 2: Prioritizing price over the substrate and materials
Two sign quotes can look nearly identical on paper and still be wildly different in what they are actually built from. I see business owners compare the bottom-line number without asking what aluminum gauge, what vinyl film, or what LED components are behind that price. A cast vinyl film built to hold up for 7 to 10 years of NJ sun and a cheaper calendared film that curls within 18 months can cost close to the same to install, but they are not the same product.
The same goes for electrical components. A non-UL-listed transformer might save a few hundred dollars on a channel letter set and then fail within a couple of years, forcing a customer to pay for the repair, the service call, and the lost visibility while the sign is dark. As a 3M certified installer, I always tell clients to ask specifically what materials are being used, in writing, before they sign anything.
Mistake 3: Designing for a screen instead of the street
A logo that looks sharp on a business card or a website often falls apart the moment it goes up as a 4-foot channel letter set on a building facade. I see this constantly: fine serif fonts that blur at driving distance, subtle color gradients that vanish in direct sunlight, and logos with fine detail that simply cannot be reproduced cleanly at sign scale.
Signage has to be designed for how it will actually be seen: a driver glancing over at 35 miles an hour on Bloomfield Avenue, or a pedestrian walking past a Montclair storefront at dusk. Letter height, stroke width, and contrast all need to be built around that real-world viewing condition, not around how the logo looks on a laptop screen. If your sign shop is not asking about approach speed and read distance during design, that is a gap worth flagging before production starts.
Mistake 4: Treating a sign as a one-time purchase instead of an asset with upkeep
Business owners often assume a sign, once installed, is maintenance-free forever. Most signage does need occasional attention: LED modules degrade over years and eventually need replacement, vinyl wraps can lift at seams if not properly reapplied after a certain age, and illuminated cabinets need periodic cleaning to keep light output even.
I recommend clients think of their sign the way they think of an HVAC system: built to last many years, but with a realistic service life on individual components. Budgeting for the occasional service call over a 10 to 15 year sign lifespan is far cheaper than waiting for a total failure and needing a full replacement.
Mistake 5: Hiring based on the fastest quote instead of checking real installed work
The last mistake, and maybe the most avoidable, is choosing a sign shop purely on turnaround time or the lowest number on a quote sheet without ever asking to see work that has been installed and weathering for several years. Renderings and proofs are easy to make look good. What matters is whether a shop’s five-year-old install still looks sharp, still lights evenly, and still meets code.
I tell every prospective client the same thing: ask to see a project from at least five years ago, and if possible drive by it yourself. A shop confident in its own work will have no problem pointing you to one. You can see examples of our own completed projects and how they have held up over time on our work page.
A sixth mistake worth mentioning: ignoring the landlord’s lease terms
I said five mistakes, and I am going to stick to that list as the core of this post, but there is a sixth issue that comes up often enough that it deserves a mention before the FAQ section. Commercial leases frequently include specific language about signage, sometimes restricting size, placement, illumination type, or even requiring landlord design approval before a tenant can install anything. I have had clients pay for a full sign design and permit application only to discover their lease required landlord sign-off they never obtained, adding weeks of delay and occasionally forcing a redesign to meet a landlord’s separate aesthetic standards for the property.
Before finalizing any sign design, I now ask every retail or office tenant client to check their lease’s signage clause, or to send it to us so we can flag anything relevant. It takes ten minutes and it has saved more than one client from a costly conflict with their landlord mid-project. A municipal permit is not the only approval that can hold up a sign installation, and business owners who only think about the township process are sometimes surprised by a landlord requirement they had not considered.
How I sequence a project to avoid all six mistakes
Over the years I have settled into a fairly consistent sequence for new sign projects specifically to avoid the mistakes above, and I think it is worth laying out because most business owners have never seen a sign project broken into stages before. First comes a site visit and a review of the location’s approach conditions, driving versus walking traffic, distance, and speed. Second is a check of the municipal sign ordinance and, where relevant, the tenant’s lease language on signage. Third is a materials conversation, substrate, film brand, and electrical components, before any design work begins, so the client understands what they are actually paying for. Only after those three steps does design work start, followed by permitting, fabrication, and installation.
Business owners who come to us after already choosing a design from another shop, or after already signing a contract elsewhere that went sideways, are almost always dealing with a project that skipped one of those first three steps. Sequencing the process this way takes a little longer at the front end. It is also the reason a very small share of our completed projects run into permit conflicts, landlord disputes, or legibility problems after installation, because those issues get caught and resolved before a single letter is fabricated.
Bonus mistake: not budgeting for the full project timeline
This one does not always make the top-five list, but it belongs in the conversation because it derails more launch dates than almost anything else: business owners frequently plan their grand opening around the day the sign order is placed, not around the actual timeline from design approval through permit review through fabrication through installation. In New Jersey, permit review alone can run anywhere from a couple of weeks to a couple of months depending on the municipality and whether the property sits in a historic overlay district. Fabrication for a custom channel letter set or monument sign typically adds another few weeks on top of that once a permit is in hand.
I have had clients call two weeks before their opening day asking why their sign is not up yet, when the permit application had only been submitted a week earlier. The fix is simple but requires discipline: start the sign conversation the moment you sign your lease or finalize construction plans, not the week before you want to open the doors. A sign shop that gives you a realistic timeline up front, even if it is not the answer you wanted to hear, is doing you a favor that a shop promising an unrealistic rush job is not.
How I train my crew to catch these mistakes before a client makes them
Most of these five mistakes are avoidable simply because someone with experience flagged them early enough. That is a big part of why I built our process the way I did: every project starts with a site walk and a permit check before a single design concept is drawn, not after. Every quote we send specifies the actual materials, substrate, and film brand being used, not a vague “premium materials” line item. Every design review includes a legibility check at the sign’s actual mounting height and approach distance, not just a look at the file on a screen.
None of that is complicated. It just requires treating the process as seriously as the fabrication itself, which is the same lesson that took me the better part of 26 years in this trade to fully internalize. A good sign shop should be catching these mistakes for you before you ever have to learn about them the hard way.
Frequently Asked Questions
What is the most common signage mistake NJ business owners make?
Choosing a final sign design before checking the local municipal sign ordinance, which can require a redesign, fines, or a forced removal if the sign does not meet zoning requirements.
How can I tell if a sign quote uses lower-quality materials?
Ask specifically what vinyl film brand, aluminum gauge, and LED or transformer components are included in writing. A shop that will not specify materials is often using lower-cost, shorter-lifespan components to hit a price point.
Why does sign design need to account for viewing distance?
Letter height, stroke width, and color contrast that look good up close or on a screen often become unreadable at driving distance or dusk. Signage should be designed for the actual approach speed and read distance of its location.
Do signs need regular maintenance after installation?
Yes. LED modules, wraps, and illuminated cabinets typically need occasional service over a 10 to 15 year lifespan, similar to other building systems, even though the sign itself is built to last for many years.
Do I need my landlord’s approval for a new sign, in addition to a municipal permit?
Often, yes. Many commercial leases include separate signage clauses that require landlord design approval independent of the municipal permit process. Check your lease or send it to your sign contractor before finalizing a design.
