MEET TERRENCE

I've been fixing cars since 1997.

I'm Terrence Blake. I started turning wrenches the year Tupac's greatest hits dropped. I spent years at a fleet company keeping box trucks and semis on the road. I've done engine swaps in parking lots and transmission rebuilds on a lift at 11pm. I've seen what shortcuts cost people, and I built Big Tee so my neighbors in Decatur would have somewhere to go that wasn't a franchise.

When you call Big Tee, you're talking to the mechanic. No service writer in the middle. No "I'll have to check with the tech and get back to you." If your car is in my bay, I'm the one under the hood.

I diagnose first. Then I tell you what it really needs. Then I quote it. In that order. If you've ever been told you need something you didn't, you'll feel the difference.

"When you call Big Tee, you're talking to the mechanic. Every time."

STARTING POINT

What's going on with your car?

If any of these sound familiar, you're in the right place. Tell me what's happening and I'll tell you whether it's a five-minute fix or something worth a closer look.

Check engine light is on

It's been on for a week and you've been ignoring it. Let's find out what it actually means.

Strange noise when you brake

Squealing, grinding, that little tick. Brakes talk before they fail.

AC blowing warm in July

Georgia summer is not the time to wing it. We'll get it cold again.

Car shakes on the highway

Vibration above 60? Probably a small fix. Probably. Let me look.

It just won’t start

Battery, starter, fuel? I'll come to your driveway and figure it out.

Transmission slipping

Don't panic. Sometimes it's a sensor. Sometimes it's the trans. Either way, I'll tell you straight.

Burning smell after driving

Could be a belt, an oil leak, brake pads. Worth a same-day look.

Dealer quoted you $3,800

Bring me the quote. Nine times out of ten there's a better answer.

WHAT I DO

Sixteen things I do — and one I don't.

From diagnostics to drivetrains, here's the work I take on every week. The one thing I don't do? Guess. Every repair starts with an honest diagnosis first.

SERVICE / 01

Mobile Mechanic

I come to your house, your job, or wherever you broke down.

SERVICE / 02

Auto Repair

Full-service repairs in the Decatur shop. Cars, trucks, everything in between.

SERVICE / 03

Car Diagnostics

Real diagnostics first. Not a guess. Not a parts-cannon.

SERVICE / 04

Check Engine Light

Code pulled, story explained, fix quoted. In that order.

SERVICE / 05

Suspension Repair

Struts, shocks, control arms, ball joints, bushings. Ride right again.

SERVICE / 06

AC Repair

Recharge, compressor, condenser, evaporator. Cold air, fast.

SERVICE / 07

Timing, head gaskets, oil leaks, sensors. Done at the shop, done right.

SERVICE / 10

Transmission Swap

When a rebuild won't do it, I'll source the trans and put it in.

Axles, CV joints, U-joints, differentials. Power gets to the wheels.

Pre-Purchase Inspection

Before you buy that used car, let me look at it. Saves people thousands.

DIAGNOSTIC-FIRST

You shouldn't have to pay for guesswork.

A lot of shops play the parts cannon: throw new parts at the car until something sticks, charge you for everything they tried. That's not how Big Tee works.

I diagnose first. I pull the codes, drive the car, listen to what it's telling me, and confirm the actual cause before touching a wrench. Then we talk about what it needs — in English, on the phone, with a written quote you can keep.

You'll spend less. You'll know what's happening. And you won't get surprised at pickup.

01
Diagnose the car, not the codes
Codes are a starting point, not an answer. I confirm root cause before I quote anything.
02
Explain it in plain English
If I can't tell you what's wrong in a sentence you'd repeat to your spouse, I haven't earned the work.
03
Quote in writing, up front
Parts, labor, timeline. Before I touch your car. No surprises at pickup, ever.
04
Fix it once, fix it right
I do the work myself. Tested before you drive away. If something is off, call me and I make it right.
HOW WE WORK

We come to you. Or you come to us. Whatever works.

Big Tee runs out of a real shop in Decatur, and I also load up the van for mobile calls across metro Atlanta. The right answer depends on the job.

Mobile mechanic

I'll come to your driveway, your office lot, or wherever you broke down. Great for batteries, starters, alternators, brake work, AC recharges, diagnostics, and most everyday fixes.

  • Driveway service in Decatur & nearby
  • Same-day visits when the schedule allows
  • Real diagnostic tools — not a parts lookup
  • Honest call when it needs to come to the shop

Shop service

Bigger jobs — engine swaps, transmission swaps, deep diagnostics, suspension overhauls — happen in the Decatur shop on a real lift, with the right tools.

  • Engine and transmission swaps
  • Heavy diagnostic work and long test drives
  • Truck, box truck, and semi capacity
  • Drop off, get a call before any work begins

NEIGHBORS TALKING

The reason people keep calling Big Tee.

Three real customers. Three real stories. This is the kind of work I'd want done on my own mom's car.

I've been bringing my truck to Terrence for three years now. He's the only mechanic I trust to give me a straight answer. My wife takes her car to him too — that's how much we trust the man.

MJ
Marcus J.
Decatur, GA · 2014 Chevy Silverado

My van died in a Publix parking lot on a Wednesday afternoon. Terrence drove out, diagnosed a fuel pump in fifteen minutes, and had it running before my groceries melted. Who does that anymore?

TW

Two dealerships told me I needed a new transmission. Quote was almost six thousand dollars. Terrence pulled it out, found a stuck solenoid, charged me a fraction of that. He found what two dealers missed.

WHY BIG TEE

Six reasons people choose their neighbor's mechanic.

None of these are slogans. They're the rules I built the shop around so it would still feel right twenty years from now.

01

You talk to Terrence directly

No service writers, no middlemen. The person fixing your car is the person on the phone.

02

No guessing — diagnoses first

I don't throw parts at a problem and bill you for the misses. I find the actual cause.

03

29 years of experience

Cars, pickups, box trucks, semis, fleets. I have seen the problem you have. Probably twice.

04

Works on cars and trucks

No vehicle is too small or too big. From a Civic to a Peterbilt.

05

Mobile + shop service

I'll come to you when it's a roadside fix. Bring it in when it's a deeper job.

06

Straight quotes, no runaround

You'll know what it costs before I touch it. And what it doesn't cost.

SERVICE AREA

We're your Decatur mechanic — and we serve all of metro Atlanta too.

Decatur is home. From the shop on the east side I cover the whole eastern arc of metro Atlanta — from Stone Mountain down to East Atlanta and out to Lithonia. Mobile calls take a little longer the further out you are, so it's worth a quick text first.

Not on the list and only a few minutes away? Call anyway. We'll figure it out.

QUESTIONS PEOPLE ASK

Good questions. Honest answers.

Who will actually work on my car?
Terrence will. That's the whole point of Big Tee. When you call, you talk to me. When you drop your car off, I'm the one diagnosing and fixing it. No revolving door of techs, no guessing about who touched what.
How do you estimate costs?
I diagnose first, then quote. Always. You'll get a clear written estimate before I do the work — parts, labor, and how long it'll take. If something changes mid-job, I call you before I do anything.
Is this a franchise or a local mechanic?
Local. I am the shop. I've been a mechanic since 1997 — worked at fleet companies, ran my own bays, and built Big Tee so my neighbors in Decatur would have a real mechanic to call.
Can you work on my older car?
Yes. Any year. Some of my favorite jobs are older vehicles. If parts are available, I can keep it running. If they aren't, I'll tell you straight.
What areas do you serve?
Decatur is home. I also serve Atlanta, Lithonia, Stone Mountain, Tucker, Clarkston, Avondale Estates, Panthersville, Belvedere Park, and East Atlanta. If you're nearby and not on that list, call — we'll figure it out.
How does mobile service work?
Call or text me with what's going on. I'll tell you whether it's something I can handle in your driveway or whether it's better to come to the shop. Mobile is great for batteries, starters, alternators, brakes, AC recharges, diagnostics, and a lot more.
READY WHEN YOU ARE

Ready to find a mechanic you can trust?
Call Terrence.

Tell me what's going on. I'll tell you whether it's a quick fix or something we need to look at. Either way, you'll get a straight answer and a real human voice on the other end of the line.

A few things people ask first

"Do you work on my year?" — Probably, yes. "Can you come to me?" — In Decatur and most nearby areas, yes. "How fast?" — Often same week, sometimes same day.
