Quoting a Repair You Cannot Fully See

I remember sitting in my workshop back in the late nineties, staring at a job ticket for a client who wanted a simple door hinge replaced, only to realize I’d spent more on petrol and travel than the actual repair was worth. I’d gone out there thinking I was doing a favour, but I was really just donating my time to the local petrol station. Most people get this wrong because they treat a small fix like a quick errand rather than a professional service. They don't realize that knowing how to price a repair job isn't about being greedy; it’s about making sure you aren't working for free.

I’ve spent forty years on site and another ten in the classroom, and I’ve seen enough botched estimates to last a lifetime. I’m not going to give you any of that fancy, spreadsheet-heavy nonsense that requires a degree in accounting to understand. Instead, I’m going to show you how to look at a job, account for your tools and your time, and walk away with a fair wage in your pocket. We’ll keep it plain, we’ll keep it honest, and we’ll make sure your skill is actually valued.

Mastering Labor Cost Estimation Over Blunt Intuition

Most young lads I taught at the college used to rely on a "gut feeling." They’d look at a broken mortise joint or a warped door, do a bit of mental math, and throw a number out. That’s a recipe for disaster. If you’re just eyeballing the work, you aren't running a business; you're gambling with your time. You need to move away from that blunt intuition and get serious about your labor cost estimation. I always told my students: if you haven't accounted for the time it takes to set up, clean up, and travel, you're effectively paying the customer to let you work.

You have to decide early on whether you’re sticking to an hourly rate vs flat rate model. A flat rate can be lucrative if you’re fast and your tools are sharp, but it only works if you know exactly how long a task should take. If you hit a snag—and in repair work, you always hit a snag—that fixed price starts eating your lunch. Don't let uncertainty bleed your margins dry; build a buffer into your time so a single stubborn screw doesn't turn a profitable afternoon into a loss.

The Truth About Parts and Materials Markup Strategies

Now, let’s talk about the bits and pieces you have to buy to get the job done. I’ve seen too many young lads treat parts like a courtesy, passing them on to the customer at cost price. If you do that, you aren't running a business; you're running a charity. When you’re out sourcing a specific brass hinge or a length of seasoned oak, you’re using your time, your vehicle, and your own money to get it. You need to implement sensible parts and materials markup to cover that gap. It isn't about being greedy; it's about ensuring the business survives to see the next job.

I always tell my students that a markup isn't just a "finder's fee." It’s how you protect your overhead and profit margins from being eaten alive by small, unexpected expenses. If you buy a specialized bit or a specific adhesive, that cost needs to reflect the effort of sourcing it. Don't just look at the receipt and copy the number. Build in a margin that accounts for the fact that things sometimes arrive broken or the wrong size. If you don't account for that risk upfront, you'll find yourself paying for the customer's repairs out of your own pocket.

Five Ways to Stop Leaving Money on the Sawdust

Factor in the travel. If you’re driving forty minutes to a job site, that’s forty minutes you aren't at the bench making money. Don't let your fuel and your time be a charity donation.
Don't forget the setup. You don't just walk in and start cutting; there's the time spent assessing the damage, cleaning the workspace, and getting your tools ready. If you don't charge for the prep, you're working for free.
Build in a buffer for the "unknowns." In repair work, you never truly know what's hiding behind a piece of rotten timber until you start digging. Always add a bit of breathing room to your quote so a hidden crack doesn't eat your entire profit.
Value your expertise, not just your hours. A man who can fix a mortise and tenon in ten minutes because he's done it ten thousand times shouldn't be penalized for being fast. You're charging for the years it took to make that ten minutes look easy.
Get it in writing, even if it's just a text. Never rely on a handshake and a "yeah, that sounds about right." Lay out exactly what you're fixing and what the cost is before you ever pick up a chisel. It keeps the job clean and the customer honest.

Don't Leave Your Livelihood to Chance

At the end of the day, pricing a repair isn't about pulling a number out of thin air because you feel like it. It’s about the discipline of knowing exactly where your time goes and making sure every bit of timber and every single screw is accounted for. If you’ve done the work to separate your labor from your materials, and you’ve applied a fair markup to cover the overheads, you aren't just guessing anymore. You are building a business instead of just chasing a paycheck. Remember, if you don't value your own expertise and the precision of your hands, no one else will. Precision in your estimates is just as important as precision with a marking gauge; if one is off, the whole project fails.

I spent forty years on site and another ten in the classroom, and if there is one thing I learned, it’s that the most expensive mistake you can make is working for free because you were too proud to charge what you're worth. A repair job is more than just fixing what's broken; it's about restoring order and providing a service that lasts. Treat your pricing with the same respect you treat a fine piece of English Oak. When you approach your books with the same steady hand you use to sharpen a chisel, you’ll find that the profit follows the quality. Now, stop overthinking it, get your numbers right, and get back to the bench.
