Write it first, then say it
Verbal instructions across a language gap have a short shelf life. The listener translates in their head, keeps the part they are confident about, and drops the qualifier. That is how "install the outlets after the electrician marks the layout" becomes "install the outlets."
Reverse the usual order. Write the instruction down first, in short sentences, then talk about it while both of you look at the written version. The written text is the record. The conversation is just the walkthrough of it.
- One instruction per sentence. Two instructions in one sentence is where half of them get lost.
- Put the condition first: "Before you close the wall, take a photo of the plumbing."
- Use numerals and spell out the unit: 16 inches, not 16" and not "a foot and a bit".
- Name the room and the wall. "Kitchen, sink wall" beats "over there".
- Say who does it. An instruction with no owner belongs to nobody.
One list, not five channels
The usual setup is a group text with the crew, email with the designer, WhatsApp with the foreman, and a paper list on the counter. Every channel holds a piece of the truth and none of them holds all of it. When something was promised in a text message three weeks ago, nobody can find it, and the argument becomes a memory contest.
Pick one place where work items live, and treat everything else as chat. If a decision happens in a phone call, it is not real until somebody adds it to the list. This is the whole idea behind MonthlyAlerts: the owner writes an item in English, the crew reads the same item in Spanish, and there is only ever one version of it.
Photos carry more than sentences do
A photo with an arrow drawn on it is not a shortcut around language. It is better than language for anything spatial. Location, layout, alignment, and "this one, not that one" all survive a photo intact.
- Mark up the photo. A circle and an arrow on your phone screenshot removes most ambiguity.
- Include a reference object for scale: a tape measure open to the dimension, a level, a stud bay.
- Ask for a photo back at the moment of completion, not at the end of the week.
- For anything about to be covered up, require a photo before it is covered. Rough plumbing, waterproofing, blocking, and insulation are the classic ones.
Confirm understanding without asking "do you understand?"
"Do you understand?" gets a yes almost every time, from almost everybody, in every language. It is a politeness question, not a comprehension question. Ask for a read-back instead.
- "Tell me what you are going to do first." ("Dígame qué va a hacer primero.")
- "What measurement did you write down?" ("¿Qué medida apuntó?")
- "When do you need my answer?" ("¿Cuándo necesita mi respuesta?")
- For anything expensive or irreversible, ask for the read-back in writing.
Drop the idioms
Idioms are the single easiest thing to remove from your own speech, and they cause a surprising share of confusion. Both machine translation and a bilingual foreman will handle plain sentences well and trip over figures of speech.
| Instead of | Say |
|---|---|
| Run it by me first | Ask me before you start |
| Ballpark number | Approximate price |
| Let's table that | We will decide that next week |
| Beef up the framing | Add a second stud here |
| We're on the same page | We agree |
| Punch list | List of items to fix before final payment |
| Call it a day | Stop work for today |
Phrases worth keeping on your phone
These use the formal usted, which is the right default with someone you do not know well. Nobody will be offended by it.

|---|---|---|
| Scheduling | What time will the crew arrive tomorrow? | ¿A qué hora llega la cuadrilla mañana? |
| Scheduling | Are we still on schedule? | ¿Seguimos a tiempo? |
| Scheduling | Will anyone work Saturday? | ¿Alguien va a trabajar el sábado? |
| Materials | When is the tile being delivered? | ¿Cuándo llega la loseta? |
| Materials | Is this the material I approved? | ¿Este es el material que aprobé? |
| Materials | Do not install it until I confirm. | No lo instale hasta que yo confirme. |
| Materials | This measurement is in inches, not centimeters. | Esta medida está en pulgadas, no en centímetros. |
| Safety | Where is the water shutoff? | ¿Dónde está la llave de paso del agua? |
| Safety | Everyone needs a hard hat in here. | Aquí todos necesitan casco. |
| Safety | Cover the floor before you start. | Cubra el piso antes de empezar. |
| Payment | Please give me the price in writing. | Por favor deme el precio por escrito. |
| Payment | Is this a change order? | ¿Es una orden de cambio? |
| Payment | I will pay when this item is finished. | Voy a pagar cuando esta tarea esté terminada. |
| Checking in | Please send me a photo when it is done. | Por favor mándeme una foto cuando esté terminado. |
| Checking in | Tell me again what you are going to do. | Dígame otra vez qué va a hacer. |
Where machine translation breaks
Translation tools are good enough for job-site sentences and have been for a while. They are not uniformly good, and the failures cluster in predictable places. Knowing the four or five weak spots is most of the defense.
Negation
"Do not grout until I approve the layout" is a sentence whose entire meaning sits in two letters. Long sentences with a negative buried in the middle are the ones that come back reversed or softened. Write the positive form instead: "Wait for my approval, then grout." A sentence that cannot be flipped by losing one word is a safer sentence.
Measurements and units
Feet and inches are the biggest risk on a US site with a crew that grew up on the metric system. Fractions are worse than decimals, and inch marks are worse than the word. Write "1/2 inch" as "half an inch" or "0.5 inch" and add the metric equivalent for anything critical. Watch the decimal separator too: 1.5 meters is written 1,5 in much of the Spanish-speaking world, and a comma in the wrong place is a factor of ten.
Words with two jobs
English construction vocabulary is full of words that are a noun, a verb, and a material at once. Level, finish, trim, plumb, stock, and second all mean at least two things. Translation picks one. Say "trim the door" or "install the door casing", never just "trim".
Time words
In Spanish, "mañana" on its own means tomorrow, while "en la mañana" means in the morning. "Tomorrow morning" needs both: "mañana en la mañana". And "primer piso" is the ground floor in some countries and the floor above it in others, so number your floors on a drawing rather than in words.
Guarding against a bad translation
- Keep the English next to the Spanish. If something looks wrong, either side can point at the original.
- Put critical numbers in a photo of the drawing rather than in prose.
- Ask for a read-back on anything that costs money to redo.
- Have the foreman confirm the day's items in writing each morning, in their own language.
- When a translated instruction produces the wrong result twice, the sentence is the problem, not the person. Rewrite it shorter.
Questions people ask
- Should I learn Spanish or use a translation app?
- Both, in that order of effort. Fifty job-site words plus the discipline of writing things down covers most of the day, and a translation tool handles the rest. What does not work is relying on a bilingual family member who is not on site, since every message then waits for a third person to be free.
- Is it rude to write instructions instead of talking?
- No, and it is usually appreciated. Written instructions protect the crew as much as they protect you, because a written scope is what proves the work was done as asked. Say it out loud as well, standing over the written version, so it does not read as distrust.
- What if the foreman speaks English but the crew does not?
- That is the common case, and it means the foreman becomes a single point of failure. Give the foreman the written list rather than a verbal briefing, and make sure the crew can read the same items themselves so a sick day does not stall the job.
- Do safety instructions need to be in Spanish?
- For employers, yes in practice. OSHA's position is that required training must be presented in a language and vocabulary the worker understands, so a safety briefing in English to a crew that does not follow English does not satisfy the requirement. As a homeowner you are not the employer, but the same logic applies to any site rule you hand out.
- How do I handle a disagreement about what was agreed?
- Go back to the written item and its date. This is the reason to keep one list rather than a text thread: an item with a date, an owner, and a photo settles most disputes in a minute. If it was never written down, treat it as a live decision and write it down now.
