The lowest bid and the best contractor are often different companies. A commercial project — a restaurant buildout, an office tenant improvement, a roof replacement — puts your opening date, your lease and your budget in someone else’s hands for weeks or months. This guide walks through how to choose well: deciding what kind of contractor you need, judging experience and capacity, checking credentials, and the questions that reveal how a contractor will actually run your job.
1. Decide what kind of contractor you need
Start with the shape of the project, because it decides who should be bidding.
- A general contractor takes responsibility for the whole job: one contract, one schedule, and the subcontractors, permits and site. If your project touches walls, ceilings and finishes plus more than one building system, you almost certainly want a GC. See commercial general contractors in Texas.
- A specialty trade contractor is the right call when the job is mostly one trade: a rooftop unit replacement, a lighting retrofit, a backflow replacement, a reroof or a parking lot overlay. Hiring the specialist directly avoids a GC markup on work the GC would subcontract anyway.
- A design-build firm handles design and construction under one contract. It can save time when you don’t have drawings yet, but you give up some of the price competition that comes from bidding a finished design. With a traditional design-bid-build approach, your architect or engineer finishes the drawings and several contractors bid the same set.
2. Match experience to your project type
Commercial work isn’t one skill. A contractor who builds excellent offices may never have coordinated a Type I kitchen hood, a grease interceptor and a health department inspection. One who does medical suites knows clinical plumbing, medical gas and infection control; one who does warehouses knows slabs, docks and rack-storage sprinklers. Ask each candidate for two or three recent projects that look like yours in type and size, and for photos or addresses you can see.
Local experience matters too. Every Texas city runs its own plan review, inspections and Certificate of Occupancy process — the steps in Dallas restaurant buildouts differ from those in a Plano office renovation. A contractor who regularly permits in your city knows what the reviewers will ask for, which shortens corrections.
3. Check credentials — especially for the licensed trades
Texas doesn’t license general contractors at the state level, so the credentials to check depend on the trade:
- Electrical and HVAC contractors are licensed by TDLR; plumbers by the Texas State Board of Plumbing Examiners; fire sprinkler, fire alarm and kitchen hood suppression companies by the State Fire Marshal’s Office.
- For a GC, confirm the business entity with the Texas Secretary of State and any city registration, and ask for the names and license numbers of the licensed subcontractors they plan to use.
- Ask for a certificate of insurance naming your business as additional insured, with limits that meet your lease.
Look licenses up yourself on the agency websites. Our commercial contractor vetting checklist covers ten things to verify, and how to find licensed contractors in Texas lists who licenses what.
4. Judge capacity and the actual team
A strong company can still be the wrong choice if it’s overloaded. Ask who will run your job day to day — the project manager and the superintendent — and whether the superintendent will be on site full time or splitting time between projects. Ask how many jobs they have running now and when they could realistically start. A contractor who says yes to every date without checking is a warning sign; one who tells you a long-lead rooftop unit will set the schedule is showing you how they plan.
5. Read the bid as a work sample
The bid itself tells you a lot. A contractor who sends a clear line-item breakdown, lists allowances and exclusions honestly, flags missing information and asks good questions during bidding will usually run the job the same way. A one-line lump sum with vague language like “per code” or “as required” tells you the opposite. Before comparing totals, adjust for scope differences using our guide to comparing contractor bids; the adjusted low bid is often not the headline low bid.
6. Talk to references the right way
Generic praise isn’t useful. Ask references specific questions: Did the project finish when promised, and if not, why? How were change orders priced and communicated? Was the superintendent on site and responsive? How did the contractor handle a problem they caused? Were there liens or payment disputes with subcontractors? Would you hire them again for the same kind of project?
7. Compare how they communicate and document
Ask what reporting you’ll get: a schedule at the start and updates as it changes, regular progress meetings or reports, and written change orders signed before extra work starts. Ask how they handle punch lists and closeout — as-built drawings, warranties, operation and maintenance manuals, and final lien waivers. Contractors with a clear process for these usually finish cleanly.
Questions to ask before you choose
- What similar projects have you completed in the last two years, and can I contact those owners?
- Who will be the project manager and superintendent, and how much time will the superintendent spend on site?
- Which parts of the work do you self-perform, and which subcontractors will you use for electrical, plumbing, HVAC and fire protection?
- What are the long-lead items on this job, and when do they need to be ordered?
- What is your change-order markup, and how do you price time-and-material work?
- Who pulls the permits, and who coordinates inspections and the Certificate of Occupancy?
- How do you bill, and do you provide lien waivers with each payment application?
- What warranty do you provide, and who do I call for warranty service?
Red flags
- Pressure to sign quickly, or a large deposit before any work or materials are on site.
- A request that you pull the building permit yourself.
- No written contract, or a contract that doesn’t attach the scope and price.
- Unwillingness to name subcontractors for licensed trades or to provide an insurance certificate.
- A bid far below the others with a long list of exclusions.
Common questions
Should I always choose the lowest bid? No. Choose the best-value bid after adjusting for scope, schedule and the contractor’s fit for your project. A slightly higher price from a contractor with directly relevant experience and a realistic schedule is often the cheaper job in the end.
Is a bigger contractor always safer? Not necessarily. Large firms bring depth and buying power, but a small or mid-size contractor may give your project more senior attention. What matters is relevant experience, capacity for your schedule and a team you trust.
Do I need an architect before choosing a contractor? If the project needs permit drawings — new walls, changed exits, or work on building systems — you will need a design professional, either hired by you or through a design-build contractor. Larger commercial projects in Texas generally require plans sealed by a registered architect or engineer.
