How to Hire a Construction Contractor in Houston: A Step-by-Step Guide

How to Hire a Construction Contractor in Houston: A Step-by-Step Guide

Here is a number most Houston homeowners never learn until it is too late: in Texas, a contractor can legally collect up to 10% of the contract price as a down payment before doing a single hour of work. That is state law, not a red flag by itself. But it tells you exactly what a one-page “estimate” with a deposit line is really asking you to risk. This guide walks you through hiring a contractor in Houston as a document review, not a personality contest, and you can find more guides & resources on our blog. You will learn what to verify, what to put in writing, and what to say to a contractor who resists either.

Quick Answer

To hire a construction contractor in Houston, verify their Texas license on the TDLR database, collect at least three written bids, and require a contract that specifies scope, price, start date, change-order terms, and a written warranty before you pay anything. Skip the verbal estimate. If the contractor will not put the price and the guarantee in writing before work starts, keep looking.

Step 1: Verify the Texas License on the TDLR Database

Texas does not license general contractors at the state level the way California or Florida does. That surprises a lot of Houston homeowners, and it should. What Texas does regulate through the Texas Department of Licensing and Regulation (TDLR) are specific trades: electricians, plumbers, and air conditioning technicians all carry state-issued licenses. A general contractor performing a kitchen remodel in Houston may hold a license for the electrical or plumbing scope, or they may subcontract those portions to licensed tradespeople. Either way, you can verify those licenses yourself in under three minutes.

Here is the step-by-step:

1. Go to the TDLR license search page at tdlr.texas.gov.
2. Select the license type: Electrician, Plumber, or Air Conditioning Contractor.
3. Enter the contractor’s name or license number.
4. Check that the license status reads “Active” and note the expiration date.
5. Confirm the name on the license matches the name on your contract.

For the general construction scope itself, the unlicensed gray zone in Texas is real. A general contractor with no state license can legally frame walls, hang drywall, set tile, and install cabinetry. That makes your written contract the primary protection. It also makes the contractor’s track record, insurance, and willingness to put guarantees in writing more important than any wall certificate. Ask for a certificate of insurance directly from the insurer, not a photocopy from the contractor. A policy can lapse the month after a copy is printed.

We have seen Houston homeowners sign with contractors who showed a TDLR license for plumbing, then discovered the actual plumber on the job was a different person with no license at all. The fix is simple: the contract should name every licensed trade that will touch the work, or state plainly that all trade work will be performed by state-licensed subcontractors with license numbers provided before that phase begins.

Step 2: Get Written Bids, Not Verbal Ballparks

A verbal estimate is a conversation. A written bid is a document you can hold someone to. The difference matters more in Houston than in markets with tighter contractor licensing, because in Texas the written contract is the enforcement tool. Without it, a dispute becomes your word against theirs.

A legitimate written bid includes at minimum:

• Total price in dollars, not a range
• Scope of work described in specific terms, including materials and finishes
• Start date or start window
• Estimated duration
• Payment schedule tied to milestones, not calendar days
• Exclusions, stated explicitly
• Warranty terms

Here is what to say to a contractor who resists written pricing: “I need a written number before I can sign anything. If the scope changes, we can do a written change order. But I will not start with a verbal ballpark.” That sentence alone filters out a meaningful share of problem contractors in the Houston market. A contractor who has done this work honestly knows the number. The one who wants to “see how it goes after demo” is telling you the number will go up.

We hear this pattern from Houston homeowners in the suburbs – Cypress, Katy, Sugar Land, Pearland – more than anywhere else. The verbal estimate starts at $28,000 for a bathroom, the paperwork never arrives, and by the time the tile is set the “final” number is $41,000. The homeowners are not wrong for being frustrated. They were wrong to start without a written price. The General Contractor in Houston you hire should hand you a written number before any work begins, not after.

Step 3: The Five Clauses Every Houston Contract Must Include

Every construction contract you sign in Houston needs five things in writing before you hand over a dollar. Skip any one of them and you are relying on goodwill, which is not a legal remedy. These five clauses do not need a lawyer to draft. They need to be explicit.

1. Scope of Work. What exactly is being built, replaced, or remodeled. “Remodel kitchen” is not scope. “Remove existing cabinets and countertops; install KraftMaid cabinets in the layout shown in drawing A; install Cambria quartz countertops with a 1.5-inch eased edge; install Kohler undermount sink and Moen faucet supplied by contractor” is scope. The more words, the fewer arguments.
2. Price. A specific dollar amount. Not a range, not a “cost-plus” estimate with no cap. If the job is truly cost-plus, the contract should state the contractor’s markup percentage and a not-to-exceed cap in writing.
3. Start Date. A calendar date or a defined window of no more than two weeks. “We will get to you sometime in the spring” is not a start date.
4. Change-Order Process. How changes to scope or price are handled. Every change should require a written change order signed by both parties before the work is performed. No signed change order, no change in price. This single clause prevents the most common form of contractor dispute in Houston.
5. Warranty Terms. What is covered, for how long, and what happens if something fails. “One-year workmanship warranty” is vague. “If any workmanship defect appears within 365 days of completion, contractor will repair or replace the defective work at no charge” is a warranty you can enforce.

If a contractor’s contract is one page and covers all five clauses, fine. Length is not the test. Specificity is. A 14-page contract with no written price and a vague scope is worse than a one-pager that names the number, the date, and the guarantee.

Step 4: How to Compare Bids That Are Not Apples-to-Apples

Three bids for the same Houston kitchen remodel can come in at $32,000, $41,000, and $55,000, and all three can be honest numbers. The spread is not always gouging. It is scope. The low bid may exclude cabinet demolition. The high bid may include a structural beam and a panel upgrade. You cannot compare the numbers until you know what is behind each one.

Ask every bidder these line-item questions:

• Does this price include demolition and debris haul-away?
• What cabinet line is priced, and is it stock, semi-custom, or custom?
• What countertop material and thickness is included?
• Does the price include plumbing fixture installation, or just the rough-in?
• Is electrical work included, and is it performed by a licensed electrician?
• Does the price include permits and inspections?
• Does the warranty cover labor and materials, and for how long?
• What is specifically excluded?

The goal is not to pick the bid with the fewest exclusions. It is to know, before you sign, what every number actually buys. In our experience, Houston homeowners who ask these questions end up making a decision based on value, not just price. A bid that looks $6,000 cheaper often becomes $6,000 more expensive once the excluded items are added back in.

One more Houston-specific note: if a bid seems suspiciously low, ask whether it includes permit fees. The City of Houston requires permits for most structural, electrical, plumbing, and mechanical work, and those fees are real. A contractor who waves off permits to keep the price down is saving you money by breaking the law and risking your insurance claim later.

Step 5: The Red-Flag Interview Checklist

The Texas Attorney General’s office publishes an annual list of top consumer complaints, and home repair and construction disputes are a fixture. Most of the complaints share the same pattern: a contractor requests a large down payment, starts work late or not at all, performs substandard work, and then disappears or refuses to return. You can screen for that contractor in a 30-minute conversation.

Red flags Houston homeowners report most often:

• Asks for more than 10% down before any work starts. Texas law caps the down payment for many residential projects at 10% of the contract price. More than that, before work begins, is a warning signal.
• Will not provide a written contract. If the entire agreement is verbal, there is no agreement to enforce.
• Pressure to sign today. Legitimate contractors do not evaporate if you take a week to compare bids.
• No physical business address. A P.O. box and a cell phone is not a business you can find if something goes wrong.
• Refuses to show proof of insurance. Every legitimate contractor in Houston carries general liability. Ask for a certificate from the insurer.
• Bad-mouths every other bid. The contractor who tells you every competitor is a crook is telling you something about how they will talk about you when you are not in the room.
• Unwilling to write the warranty down. “I will take care of you” is not a warranty. Get it in writing.

We have talked to Houston homeowners in neighborhoods like Meyerland and Oak Forest who ignored one or two of these red flags and regretted it. Almost none of them ignored all seven. The checklist is not about paranoia. It is about recognizing that a contractor’s behavior before the contract predicts their behavior after it.

Step 6: Houston-Specific Considerations: Climate, Code, and Timing

Houston does not have a mild construction climate. It has heat, humidity, and hurricane season. All three affect a remodel in ways a contractor from Dallas or Austin may not fully account for. A Houston contractor should be planning for moisture from day one, because your house has been living with it.

Here is what to ask any contractor about Houston conditions:

• Moisture and substrate. In a bathroom remodel, the cement board substrate (the moisture-resistant layer behind your tile) matters more in Houston than in Phoenix. Ask what waterproofing system they use. Schluter’s Kerdi membrane and similar systems are built for high-humidity environments. If the contractor cannot name their waterproofing system, keep looking.
• Hurricane season timing. Roofing and exterior work between June and November faces weather delays. A good Houston contractor builds weather contingencies into the schedule instead of pretending the sky will cooperate. Ask how weather delays are handled in the contract.
• Foundation movement. Houston’s clay soil expands and contracts with moisture. A remodel that does not account for slab movement – especially tile work – can crack within a year. Ask whether the contractor checks for slab flatness and movement before tile installation.
• City of Houston permitting. The city’s permitting process is its own animal. A contractor who knows Houston’s permit office can pull permits correctly the first time. One who does not will blame the city for delays that are really inexperience.

The product brands behind the work matter here too. GAF roofing products carry wind ratings that matter in a hurricane zone. Sterling and Grohe fixtures are built to handle Houston’s hard water better than low-end imports. A contractor who names specific brands is making a statement about what they will stand behind.

Step 7: Get the Guarantee in Writing

The guarantee is the clause that separates a professional remodel from a gamble. Every contractor will say they stand behind their work. The question is what happens when the tile cracks at month ten and you call. If the guarantee is verbal, the answer is often nothing. If it is written, the contractor has a legal obligation.

A written guarantee should tell you four things:

• What is covered: workmanship, materials, or both
• How long the coverage lasts
• How to make a claim
• What the contractor will do if the work fails

Our approach at Penhallow Remodeling Houston home is the 365-Day Done Right Promise: if the work is not done right during the guarantee period, we come back and fix it at no charge. It is in writing on every project. Not because Houston homeowners are suspicious, but because they have reason to be. The Kingswell standard behind that promise is simple: say the price before the work. Show up in the window you gave. Leave the place cleaner than you found it. That is the bar.

For Kitchen Remodeling in Houston and Bathroom Remodeling in Houston, the guarantee should cover cabinets, countertops, tile, plumbing, and electrical. If a cabinet door warps in month nine, that is covered. If a tile cracks because the substrate was installed wrong, that is covered. The homeowner should not have to know the difference between a product defect and a workmanship defect to get the problem fixed.

Common Mistakes to Avoid

• Signing before reading the exclusions. The exclusions section is where low bids hide. Read it line by line, and ask what each exclusion would cost to add back.
• Paying too much up front. In Texas, more than 10% down before work starts is legally capped for many residential jobs. Protect your leverage: pay increments tied to completed, inspected milestones.
• Skipping the permit. Unpermitted work can void your homeowner’s insurance and complicate a future sale in Houston. If the contractor suggests skipping permits, you are hiring the wrong contractor.
• Choosing the middle bid by default. The middle number is not automatically the right number. Compare scope, materials, and warranty, then decide.
• Ignoring the change-order clause. Without a written change-order process, a $5,000 change becomes a $12,000 surprise. Read that clause before you sign, not after the surprise.
• Not checking the TDLR license. Three minutes on the TDLR website saves thousands of dollars and months of frustration when a trade goes wrong.
• Believing “I’ve been doing this 30 years” without verification. Experience is real, but it is not a license, not insurance, and not a guarantee. Verify everything.

When to Call a Professional

Some projects are safe to attempt yourself. Painting a bedroom, swapping a faucet washer, caulking a tub. But any remodel that involves plumbing, electrical, load-bearing walls, or waterproofing deserves a professional, and in Houston the humidity raises the stakes. A shower that leaks behind the tile may not show itself for months, by which time the damage is behind the walls. If your project involves moving a drain line, opening a wall, running new circuits, or tiling a wet area, call a contractor who will put the price and the guarantee in writing.

The Bottom Line

Hiring a contractor in Houston is not about finding the friendliest person or the lowest number, and our Complete Guide to Construction in Houston covers additional steps worth considering. It is about getting every meaningful commitment into writing before money changes hands: the price, the scope, the start date, the change-order process, and the guarantee. Houston homeowners are protected less by state licensing than by the contracts they sign, so the document is the thing. Verify the TDLR license for any trade work, get three written bids, compare them line by line, and hold the contractor to the number and the promise they made on day one.
