The Borderland is one metro area with two rulebooks. Cross the state line and the rules for who’s allowed to remodel your kitchen change completely: New Mexico requires general contractors to hold a state license, while Texas famously has no statewide general contractor license at all. If you own a home here — or you’re a military family that just PCS’d in and doesn’t know a soul who can recommend anyone — this guide is your vetting system: what each state actually requires, how to check a license in two minutes, and the red flags that should end a conversation immediately.
The good news: vetting a contractor isn’t complicated. It’s a short checklist, done in order, before any money changes hands. The contractors worth hiring will pass every step without flinching. The ones who push back on any of it are telling you something — believe them.
The New Mexico Side: State Licensing Through CID
In Las Cruces and everywhere else in New Mexico, general contractors are required to hold a state license issued through the Construction Industries Division (CID). The classification you’ll see most often on residential work is GB-98 — the common residential general building license. If someone wants to remodel your kitchen, build your addition, or convert your garage in New Mexico, ask for their license number before you ask for their price.
Checking it takes about two minutes. The New Mexico Regulation & Licensing Department runs a public license lookup — search the contractor’s name or license number and confirm the license is active, matches the person in front of you, and covers the type of work you’re hiring for. A contractor who volunteers their license number without being asked is a good early sign. One who gets vague about it is not.
The trades are licensed too. Electricians, plumbers, and mechanical contractors in New Mexico carry their own state licenses, so if your remodel involves moving wiring or supply lines, the people doing that specific work should be licensed for it — whether they’re on the GC’s payroll or subcontracted in. It’s fair to ask your general contractor who is doing the electrical and plumbing and whether they’re licensed. A good GC answers that question in one sentence.
The Texas Side: No Statewide GC License — So What IS Checked?
El Paso homeowners face a different landscape. Texas has no statewide general contractor license. Anyone can print business cards that say “general contractor” and be legally accurate. That doesn’t mean nothing is regulated — it means the regulation lives at the trade level and the city level, and the burden of vetting shifts more heavily onto you.
Here’s what Texas does license: electricians and air conditioning contractors are licensed through the Texas Department of Licensing and Regulation (TDLR), and plumbers are licensed through the Texas State Board of Plumbing Examiners. Both agencies have public lookups. So while you can’t verify a “GC license” in El Paso, you absolutely can verify the electrician rewiring your kitchen and the plumber moving your drain lines — and you should.
Cities add their own layer. Contractors working in El Paso generally need to register with the city and pull permits through its development-services process for structural, electrical, and plumbing work. A contractor who is registered with the city and pulls permits routinely has left a paper trail you can trust more than any brochure. One who works permit-free and off the books has left no trail on purpose. For more on how that process works on both sides of the line, see our guide to remodel permits in Las Cruces and El Paso.
The Universal Vetting Stack (Works in Both States)
Whichever side of the line you live on, run every candidate through the same five steps, in this order:
- License first. In New Mexico, verify the GB-98 (or relevant classification) through the RLD lookup. In Texas, verify every licensed trade that will touch the job — TDLR for electrical and AC, the state plumbing board for plumbers.
- Insurance — and actually call the insurer. Ask for a certificate of insurance showing general liability and, where applicable, workers’ comp. Then call the insurance company listed on the certificate and confirm the policy is current. Certificates are easy to fake; a phone call is not.
- References that are a year old. Fresh references tell you the contractor is charming. Year-old references tell you whether the tile is still on the wall and whether he answered the phone when something needed fixing. Ask specifically for jobs completed about a year ago.
- A written, itemized contract. Not a one-line estimate on letterhead. Scope, materials, allowances, timeline, payment schedule — in writing, before work starts.
- Milestone payments. Money changes hands when work is completed, not before. A reasonable deposit up front, then payments tied to visible progress, with the final payment held until the punch list is done.
Red Flags That Should End the Conversation
Some warning signs deserve a second look. These don’t — they deserve a polite goodbye:
- Full payment up front. No legitimate contractor needs the whole job funded before the first hammer swings.
- “We can skip the permit and save you money.” The permit protects you, not them. A contractor who dodges inspections is asking you to carry the risk of their shortcuts.
- Storm-chasing door-knockers. After monsoon season hail or wind, crews appear at doors offering same-day roof and stucco repairs. Local, established contractors are busy after storms — they’re not canvassing neighborhoods.
- No local, physical address. A phone number and a P.O. box is not a business you can find later if something goes wrong.
- Pressure to sign today. “This price is only good right now” is a sales tactic, not a construction schedule.
- Cash only. Cash-only means no paper trail — which is exactly the point.
What Belongs in the Contract
A good contract is boring, specific, and slightly too long. At minimum it should spell out: the scope of work in enough detail that a stranger could tell what’s included and what isn’t; allowances for items not yet selected (fixtures, tile, countertops) with realistic dollar figures stated per item; a change-order process requiring written sign-off and a price before extra work happens; a timeline with a start date and a realistic completion window; the payment schedule tied to milestones; and the warranty — what’s covered, for how long, and in writing. If a contractor resists putting any of this on paper, that’s your answer about how the job will go.
Quick FAQ
What’s a normal deposit? Commonly 10–30% of the contract price, sometimes more when custom materials must be ordered early. A demand for most or all of the money up front is a red flag, full stop.
What if they damage my home? This is exactly why you verified insurance before signing. Document the damage with photos immediately, notify the contractor in writing, and if it isn’t resolved promptly, contact their liability insurer directly using the certificate you collected. Homeowners who skipped the insurance step have far fewer options.
Can I check a contractor’s complaint history? In New Mexico, the state license lookup is your starting point for license status and standing. In both states, check the Better Business Bureau, ask the contractor directly whether they’ve had disputes and how they resolved them, and weigh those year-old references heavily. No contractor has a spotless decade — what you’re looking for is how they behave when something goes sideways.
