Measure Twice, Cut Once:
Why We Do It Right the First Time

By Nick Jancovic  ·  June 8, 2026  ·  Einstein Plumbing USA

There is an old saying in the trades that every apprentice hears on their first week: measure twice, cut once. It sounds simple. It sounds obvious. And yet, in 15+ years of doing this work, I can tell you that the single most common cause of plumbing problems I get called in to fix is someone — a homeowner trying to DIY, or a low-bid contractor trying to move fast — who skipped the measuring and just cut.

At Einstein Plumbing USA, doing the job right the first time isn't a marketing slogan. It's the standard we hold ourselves to on every project — commercial new construction, a residential addition, or a water heater swap. Here's what that actually means in practice and why it matters more than most people realize.

What "Measure Twice" Actually Means in Plumbing

In carpentry, the phrase is literal — you measure a board before you cut it so you don't waste material. In plumbing, it means something broader. It means you understand the full scope of what you're doing before you start. You read the plans. You look at existing conditions. You think through where the drain needs to go before you open the wall. You check water pressure before you spec a water heater. You verify gas line sizing before you commit to a tankless unit.

The "measuring" in plumbing is the thinking, the planning, and the asking of questions that most people skip because they're in a hurry or trying to keep the bid low. And that's exactly where problems are born.

I've walked into more jobs than I can count where a previous plumber cut a drain line 2 inches short because they didn't account for a fitting, roughed in a shower in the wrong location because they didn't read the tile layout, or undersized a gas line because they didn't add up the BTU load from all the appliances on the run. Every single one of those mistakes required tearing into finished work to fix. Every one of them cost the homeowner more than the original job would have.

The Real Cost of Getting It Wrong the First Time

When a plumber gets something wrong — especially rough-in work that gets closed up behind tile, drywall, or concrete — the cost to fix it is almost always 3 to 5 times what it would have cost to do it right the first time. You're not just paying for the plumbing correction. You're paying for:

• →Demo and disposal of the finished work that has to come out
• →The plumbing correction itself
• →Patching and refinishing whatever was opened up
• →The schedule delay while all of the above happens
• →The stress of dealing with a contractor coming back to fix what they should have done right the first time

On a commercial job, a rough-in error can cascade through the entire trade sequence. If plumbing is wrong, tile can't go in. If tile doesn't go in, cabinetry gets delayed. If cabinetry is delayed, the GC can't close out the permit. I've seen a single misplaced floor drain push a restaurant opening back three weeks. Three weeks of lost revenue because someone didn't measure twice.

Why First-Time Inspection Passes Matter

In Chicago and Chicagoland, every permitted plumbing project goes through inspection. An inspector comes out, looks at the rough-in, and either passes it or doesn't. A failed inspection — called a "correction" — means the work has to be redone and re-inspected before construction can continue.

We pass first-time, every time. That's not luck. That's what happens when you know the code cold, you do the work to the standard the inspector expects, and you don't cut corners because you're in a hurry or because you think no one will check. Someone always checks.

For homeowners, a failed inspection on a remodel or addition can also create complications when you eventually sell your home. A permitted job with clean inspection records protects your property value. An un-permitted or botched job that gets discovered during a sale can kill a deal or cost you a significant price reduction at closing.

What Doing It Right Looks Like in Practice

When Einstein Plumbing USA takes on a job, here's what "doing it right" looks like before we ever pick up a tool:

• →We read the full scope. On commercial jobs, we read the architectural drawings, coordinate with the GC on sequencing, and identify conflicts before they become field problems.
• →We look at existing conditions. On residential jobs, we evaluate what's behind the walls before we commit to a layout. Old Chicago homes especially have surprises — we find them before they find us.
• →We write a clear scope. Every job gets a written estimate with inclusions and exclusions clearly stated. No verbal agreements, no surprises on the invoice.
• →We pull permits on every job. No exceptions. A permitted job is a protected job — for you, for your home, and for your investment.
• →We back it with a 1-year guarantee. If something we did isn't right, we come back and make it right. That's what standing behind your work means.

The Lowest Bid Is Rarely the Lowest Cost

I understand the instinct to take the lowest bid. Construction is expensive. Plumbing is expensive. But the lowest bid and the lowest total cost are almost never the same thing. The lowest bid is usually low because something is being skipped — permits, materials quality, experience, or time spent doing it right.

We're not the cheapest plumber in Chicago. We're also not the most expensive. What we are is consistent — in how we show up, how we work, and how we treat your home or job site. Over 15 years and more than 1,000 projects, that consistency is what keeps general contractors calling us back for every build and what keeps homeowners referring us to their neighbors.

Measure twice. Cut once. Do it right the first time. It's not complicated — it's just a standard most people have stopped expecting. We haven't.
