Most homeowners start researching repipe companies after something goes wrong. A burst pipe in the wall, rust-colored water at the kitchen tap, or a failed hydrostatic test that shows up during a home sale. The urgency makes it tempting to just call someone, get a quote, and get it done.
That urgency is also how homeowners end up with the wrong crew.
Choosing a repipe contractor is not the same as hiring a general plumber for a faucet swap. A whole-house repipe is a multi-day project that opens your walls, replaces your entire water distribution system, and either leaves your home looking the way it did or… does not. The contractor you hire makes the difference between a clean finish with a warranty behind it and a patchwork job you are paying someone else to fix six months later.
These six questions will help you tell the difference before any work begins.

1. Are You Licensed and Insured for This Scope of Work?
This sounds obvious, but it is where a surprising number of homeowners skip the follow-up. Texas requires plumbers to be licensed through the Texas State Board of Plumbing Examiners, and any contractor pulling permits for a whole-house repipe should be able to show you a current license without hesitation.
Ask specifically:
- Is the crew lead a licensed master plumber or journeyman working under one?
- Does your liability insurance cover property damage if something goes wrong during the repipe?
- Do you pull permits for every repipe, or only when required?
Permit-pulling matters beyond the legal checkbox. A permitted repipe gets inspected, which means a third-party set of eyes on the work before the walls close up. Unlicensed contractors who skip permits are also skipping that accountability layer entirely.
BBB accreditation is a useful secondary signal here. It does not replace licensing, but it does indicate that the company has agreed to follow ethical business practices and responds to complaints through a documented process.
2. What Material Do You Use, and Why?
If a contractor cannot clearly explain what pipe material they install and why it is appropriate for your home, that is a red flag. There are meaningful differences between copper, standard PEX, PEX-A, CPVC, and PVC, and the choice has real implications for longevity, flexibility, and how the pipe handles Houston’s climate.
Copper has been the residential standard for decades. It is durable and resistant to UV, but it corrodes in acidic water conditions, is vulnerable to the kind of hard freeze events that periodically hit the Houston area, and carries a higher material cost.
PEX-A is currently the preferred material for whole-house residential repiping in most markets, including Houston. Uponor PEX-A specifically is cross-linked at a higher density than standard PEX-B or PEX-C, which gives it better flexibility, superior freeze resistance due to its ability to expand and recover, and a smoother interior bore that resists scale buildup over time. Uponor is one of the most widely recognized names in the PEX-A space and their fittings system uses an expansion connection method rather than crimp rings, which creates a stronger, less failure-prone joint.
When you are comparing quotes, ask specifically what brand and grade of PEX is being used. “PEX” as a category is not uniform.
3. Does Your Quote Include Drywall Repair and Paint?
This question eliminates a huge category of post-project surprises.
To run new pipe through a home, the crew needs access. That means cutting holes in drywall, sometimes multiple per room, depending on the layout. Many plumbing companies, including general plumbers who offer repiping as a side service, complete the pipe work and then hand the homeowner a list of drywall contractors to call.
That is not a finished job. It is a job half done.
Ask directly: do you restore the walls before you leave, or do I need to hire a separate contractor? A reputable Houston repipe company will include drywall patching, texture matching, and paint in the project scope, not as an optional add-on.
When this work is included, you also get one point of accountability. If the wall finish does not match or a patch cracks, you call the same company. When drywall and plumbing are handled by separate crews, the accountability tends to evaporate quickly.
4. What Does Your Warranty Cover, and Is It Transferable?
Warranty terms vary enormously in this space and most homeowners do not read them closely enough until they need to use one.
Ask the following:
- What is the warranty period on the pipe work?
- Does the warranty cover labor as well as materials?
- Is the warranty transferable if the home is sold?
The transferability question is particularly relevant for homeowners who plan to sell within the next five to ten years. A transferable lifetime warranty on a repipe is a legitimate selling point that can reassure buyers and their inspectors. A non-transferable warranty, or one that voids upon ownership change, offers none of that protection.
Specialist repipe companies are more likely to offer transferable warranties because the warranty reflects confidence in a process they repeat daily. A generalist plumber who repiped two homes last year has less institutional confidence to stand behind a lifetime claim.
5. How Do You Price the Work, and What Is Not Included?
Pricing transparency is one of the clearest indicators of contractor quality. Vague quotes that give you a range without a clear breakdown are often how scope creep starts.
The most defensible pricing model in whole-house repiping is fixed per-fixture pricing, where the cost is calculated based on the number of plumbing fixtures in the home, not the size of the house or its location. This approach is fair, predictable, and easy to compare across quotes.
Be direct in asking:
- Is this a fixed price or an estimate that could change?
- Are permits included in the price?
- Is drywall repair and paint included, or priced separately?
- Are there any conditions that would change this quote?
Location-based markups are worth asking about specifically. Some contractors price differently based on the neighborhood or zip code, which creates inconsistency that has nothing to do with the actual scope of work. A per-fixture model eliminates that entirely.
On the question of affordability, it is worth knowing that financing options exist for this type of project. A whole-house repipe in Houston typically runs between $4,000 and $16,000 depending on the size and complexity of the home, and 0% financing over 24 months can make a project that feels out of reach genuinely manageable without tapping savings.
6. How Many Whole-House Repipes Have You Actually Completed in Houston?
This question separates the specialists from the generalists, and the answer should come with some substance behind it.
A plumbing company that does repiping occasionally handles it differently than a crew that repiped three homes this week alone. The speed, the quality of the access cuts, the drywall patching, the routing decisions inside tight wall cavities, all of it improves with repetition at scale.
Ask specifically about Houston-area repipes, not just general plumbing jobs. Houston’s housing stock, particularly homes built between the 1970s and early 2000s with galvanized or original copper systems, has its own characteristics. A crew experienced in this region knows the layout patterns, the common complicating factors, and how to keep the project on schedule.
Volume matters, but so does verification. Ask to see reviews from local homeowners, check Google and the BBB, and look for patterns in what people say, not just the star rating.
When researching your options, Houston Repipe company Repipe Solutions Inc has completed more than 10,000 repipes across the Houston area, with over 100 five-star reviews reflecting consistent feedback on workmanship, communication, and finish quality.
Specialist vs. Generalist: Why the Distinction Matters Here
There is a meaningful difference between a licensed plumber who can repipe a house and a company whose core business is whole-house repiping.
Generalist plumbers are skilled at what they do. But repiping is a volume and process game. The crew that does five repipes a week has refined the access-cut pattern, the rerouting logic, the drywall patch sequence, and the pressure testing process to a level that shows in the finished product and the timeline.
Specialist repipe companies also tend to have direct relationships with material suppliers, which affects both material quality and consistency. If a crew uses Uponor PEX-A on every job, they source it regularly, they know the fittings system inside out, and they are not improvising with whatever is available at the supply house that morning.
The warranty difference is also structural. A company that stakes its entire business reputation on repipe quality has more reason to stand behind a transferable lifetime warranty than a generalist for whom repiping is a fraction of the revenue.
Key Takeaways
- Always verify licensing, insurance, and permit-pulling practices before any work begins. These are not formalities.
- Ask specifically about pipe material grade. PEX-A and PEX-B are not the same product, and Uponor PEX-A carries specific performance advantages for Houston homes.
- Confirm that drywall repair and paint are included in the quote, not handled separately. A repipe without wall restoration is an incomplete job.
- Read warranty terms carefully, and specifically ask whether they transfer to a new owner. This matters more than most homeowners realize until they go to sell.
- Volume and local experience matter. A crew that has completed thousands of Houston repipes has solved problems you have not even encountered yet.
FAQ
How long does a whole-house repipe typically take in Houston? Most whole-house repipes in Houston are completed in one to two days. Water is typically off for five to six hours during active work and restored at the end of each working day, so homeowners rarely need to make alternative living arrangements.
Is PEX-A better than copper for Houston homes? For most Houston homeowners, PEX-A offers practical advantages over copper, including better freeze resilience, resistance to the slightly acidic water conditions common in parts of the Houston area, and lower material cost. Copper remains a durable option but tends to come at a higher price point and is more vulnerable to pinhole corrosion over time in certain water conditions.
What should I expect a whole-house repipe to cost in Houston? Project costs typically range from around $4,000 to $16,000 depending on the number of fixtures, home size, and whether drywall repair is included. Fixed per-fixture pricing is the clearest model to compare across contractors, as it removes location-based variables from the equation.
Does a repipe require permits in Texas? Yes. A whole-house repipe in Texas requires a permit, and the work must be inspected by a licensed inspector before the walls are closed. Any contractor who suggests skipping the permit process is creating liability for the homeowner, not saving them time.
Why does transferability matter in a repipe warranty? If you sell your home, a transferable warranty passes that protection to the new owner, which is a real value-add during negotiations or inspection contingencies. A warranty that voids at the point of sale offers no downstream protection and is difficult to use as a selling point.
Closing Thoughts
Choosing a repipe contractor comes down to asking the right questions before the first pipe is cut. Licensing, materials, wall restoration, warranty terms, pricing transparency, and proven local experience are not secondary concerns. They are the factors that determine whether a project goes smoothly or becomes a second expensive problem to solve.
Take the time to ask these questions of every contractor you are considering. The answers will tell you a great deal about how seriously each company takes the work and the people they are doing it for.
