Frequently asked questions

Yes. FlexFix is a mobile mechanic service—we travel to your home, workplace, or many roadside situations. Availability depends on distance and job type; call or message to confirm.

Call or text the number on this site, message our Facebook page, or reach out through Marketplace listings. We will confirm your vehicle, issue, and address.

We accept common methods including cash and major cards where equipment is available—confirm when you book.

We prioritize urgent situations when capacity allows. Describe your symptoms and location and we will advise timing.

Most passenger cars and light trucks. Share your year, make, and model for specialty or heavy-duty requests.

Often yes for common parts; some items may require ordering. We source quality parts and keep you informed on timing and price before work proceeds.

A mobile mechanic is an ASE-certified technician who brings scan tools, lifts, and core equipment to your home, office, parking lot, or roadside—so you skip the tow and the service lane queue when the job can be done on-site.

We routinely work from driveways, carports, and parking lots. If weather is unsafe or would damage tools or electronics, we reschedule or coordinate door pick-up / drop-off when that fits your situation.

The $60 covers a professional, tool-based assessment—not guesswork. If you approve the quoted repair, that $60 is credited toward the labor for that job, so you are paying for a defined outcome, not a mystery add-on.

No. Many customers use contactless service: keys in a agreed secure location, updates by phone or text, and a digital summary when the work is complete—provided the property rules and job type allow it.

Qualifying repairs include a 12-month / 12,000-mile limited warranty on parts we supply and our workmanship (whichever comes first), with industry-standard exclusions—see our About page for full warranty language.

Often yes for comparable labor on jobs we can do on-site—without the same rent and fixed front-office overhead as a big brick-and-mortar shop, and without a tow when you are not broken down at a facility. Every vehicle is different; we quote clearly after a $60 mobile diagnostic and only move forward with work you approve.

We charge a flat $60 mobile diagnostic in the areas we serve (Katy, Sugar Land, Cypress, and Greater Houston). That covers professional inspection and testing—not a guess. If you approve the quoted repair, the $60 is credited toward labor on that job.

We would not ignore it. The light means the computer stored a fault—sometimes it is minor (like a loose fuel cap), sometimes it is a sensor or misfire that can damage the catalytic converter or engine if it gets worse. A $60 on-site diagnostic tells you what you are dealing with before it becomes a bigger bill or a tow.

We serve Katy, Sugar Land, Cypress, and the greater Houston metro area. If you are outside those zones, call or text us—we may still be able to reach you depending on the job.

It depends on the job. A diagnostic takes about 30–60 minutes. Common repairs like brake pads, alternators, or starters are usually done in 1–3 hours. We give you a time estimate before we start so you can plan your day.

Yes, as long as the complex allows it and we have safe, level access to the vehicle. Some complexes have rules about outside service—check with management, and we will coordinate a nearby meetup if needed.

Yes. We bring quality oil and filters to your location. Conventional, synthetic blend, and full synthetic options are available. We also handle used oil responsibly in line with EPA expectations.

Yes. We test the battery and charging system on-site, and if it needs replacement, we carry common sizes or source one quickly. The old battery is removed and recycled properly.

We are available Monday through Saturday by appointment. Sunday availability is limited but possible for emergency situations—contact us and we will let you know.

If the repair requires a shop bay, lift, or specialized equipment we do not carry, we will let you know upfront and help coordinate next steps—whether that is a tow to a trusted facility or a door pick-up arrangement.

Yes. Before you buy a used car, we can meet you at the seller's location and perform a thorough multi-point inspection—mechanical, electrical, and visual—so you know what you are getting before you commit.

Yes. No-start conditions are one of our most common calls. We test the battery, starter, fuel system, ignition, and computer to pinpoint the cause—then quote the fix before proceeding.

Warning signs include squealing or grinding noises, a soft or pulsating brake pedal, the car pulling to one side when braking, or a brake warning light on the dash. We can inspect pads, rotors, and fluid on-site.

We diagnose and recharge AC systems on-site. For more complex AC work like compressor or evaporator replacement, we evaluate whether mobile conditions allow it and let you know before starting.

You can, but our warranty only covers parts we source. Customer-supplied parts carry no warranty from us on the part itself—only on the labor we perform. We are happy to discuss sourcing options.

Our lead technician holds ASE certification with strength in electrical diagnostics and suspension, plus training rooted in official Ford Customer Service Division programs—the same rigor as a Lincoln-Ford service lane.

We handle many diesel diagnostics and common repairs on light-duty diesel trucks and SUVs. Share your vehicle details and the issue, and we will confirm whether we can service it on-site.

OEM parts are made by or for the vehicle manufacturer—exact fit and spec. Aftermarket parts are made by third parties and can range from budget to premium quality. We help you choose based on your budget and needs.

We can clear the code, but clearing without fixing the underlying issue usually means the light comes back. Our $60 diagnostic identifies the root cause first, then we clear codes after the repair is complete.

Yes. A modern tune-up typically includes spark plugs, ignition coils if needed, air filter, and a scan for pending codes. We also inspect belts, hoses, and fluid levels as part of the visit.

Yes. Overheating calls are common in Houston heat. We check the coolant level, thermostat, water pump, radiator, hoses, and cooling fans. Do not drive an overheating car—pull over safely and call us.

Yes. Starters and alternators are among our most common mobile repairs. We test the entire starting and charging system before replacing anything to make sure we fix the actual problem.

We handle many hybrid maintenance tasks—brakes, suspension, 12V batteries, and diagnostics. Full EV high-voltage work typically requires specialized facilities. Contact us with your vehicle details.

We do not provide towing, but we can recommend trusted tow services in the Houston area. Often our mobile service eliminates the need for a tow entirely—that is the point of coming to you.

Yes. We pressure-test the cooling system to find the source—hose, clamp, water pump, radiator, or gasket. Once identified, we quote the repair and only proceed with your approval.

Yes. A worn or cracked serpentine belt can cause squealing, loss of power steering, and AC failure. We inspect the belt and tensioner and replace them on-site when needed.

Yes. Brake fluid absorbs moisture over time, which lowers its boiling point and can affect braking performance. We bleed and replace the fluid with fresh DOT-spec fluid on-site.

Common signs include clunking over bumps, excessive bouncing, uneven tire wear, the vehicle pulling to one side, or a rough ride. We inspect shocks, struts, ball joints, and bushings on-site.

Yes. We replace bulbs, restore cloudy lenses, and install upgraded lighting when compatible. Properly working lights are a safety essential—especially for Houston night driving.

Yes. We diagnose power steering groans, leaks, and stiff steering—checking the pump, rack, fluid level, and hoses. Most power steering repairs can be done on-site.

A flashing check engine light usually indicates an active misfire that can damage the catalytic converter. Reduce speed, avoid hard acceleration, and call us for a diagnostic as soon as possible.

Yes. We work with small fleets, delivery vehicles, and business owners who cannot afford downtime. We can schedule recurring maintenance or handle on-call repairs at your lot or facility.

Yes. Stalling can be caused by fuel delivery issues, ignition problems, sensor failures, or electrical faults. Pull over safely, and we will come diagnose the root cause on-site.

Yes, on most vehicles. The water pump is critical for engine cooling—if it is leaking or failing, the engine can overheat quickly. We test and replace it on-site when access allows.

TPMS stands for Tire Pressure Monitoring System. The light means one or more tires are low. Check pressures when tires are cold and inflate to the spec on the driver door sticker. If it stays on, a sensor may need service.

Yes—electrical diagnostics is one of our strongest areas. We trace wiring, test circuits, check grounds, and use scan tools to find parasitic drains, short circuits, and sensor failures.

Yes, on most vehicles where mobile access allows. Fuel pump failure often causes no-start or stalling conditions. We test fuel pressure first to confirm the pump is the issue before replacing it.

It depends on your vehicle and oil type. Most modern cars with synthetic oil go 5,000–7,500 miles between changes. Check your owner's manual or ask us—we will recommend the right interval for your driving conditions.

Yes. Vibrations at speed are commonly caused by unbalanced tires, worn suspension components, warped brake rotors, or drivetrain issues. We diagnose the source and quote the fix.

Yes. If your radiator is leaking, clogged, or damaged, we can replace it on-site for most vehicles. We pressure-test the system before and after to confirm the repair is solid.

Burning rubber can mean a slipping belt or hot brake. Rotten eggs (sulfur) often points to a catalytic converter issue. Either way, do not ignore unusual smells—call us for a diagnostic.

Yes. Worn spark plugs or failing coils cause misfires, rough idle, and poor fuel economy. We test each cylinder and replace only what is needed—no unnecessary parts.

We diagnose transmission problems—hard shifts, slipping, fluid leaks, and warning lights. Fluid changes and minor repairs can be done on-site; internal rebuilds require a shop facility.

Yes. Many of our customers schedule service at their office parking lot so they do not lose a workday. We work quietly and clean up after the job—just confirm your employer or property allows outside service.

A parasitic drain is when something in the car keeps drawing power after the engine is off—killing the battery overnight or over a few days. We use a multimeter to test each circuit and find the source.

Our standard hours are Monday–Saturday by appointment. We do our best to accommodate late-afternoon and early-evening requests. For after-hours emergencies, call or text and we will advise.

We diagnose catalytic converter issues and can replace them on most vehicles where mobile access allows. We test upstream and downstream O2 sensors to confirm the converter is the root cause.

Park on a flat, level surface with enough room to open the hood and access the sides. If possible, leave the area well-lit and clear of obstacles. Let us know about any gate codes or parking restrictions.

We value loyalty and aim to keep our pricing fair for everyone. Repeat customers benefit from our familiarity with their vehicle history, which can speed up diagnosis and reduce labor time.

Yes. Power window failures are usually caused by a bad motor, regulator, or switch. We test the electrical circuit and replace the failed component on-site.

Note the color (dark brown/black = engine oil) and where the puddle forms. Do not ignore it—low oil can cause engine damage. Call us for a diagnostic; we will find the source and quote the repair.

We focus on mechanical and electrical repair rather than cosmetic or accessory installs. However, if the item is safety-related (like lighting upgrades), ask us—we may be able to help.

Call or text us with your year, make, model, mileage, and a description of the problem. We can give a ballpark estimate over the phone, but a precise quote requires the $60 on-site diagnostic to confirm the root cause.
