Text Message Opt-In

Last updated September 26, 2026

This page shows how people opt in to text messages from Modern Mountain Builders LLC (doing business as 25th Hr) and from contractors who use 25th Hr's missed-call answering service.

How you opt in: you call us first

We only text a phone number that has called the business. There is no list, no sign-up form and no marketing. Here's what happens when we can't pick up:

1. You call the business phone number. If no one can answer, the call forwards to our answering line.
2. The answering line plays this message before any text is sent:

   "Thanks for calling 25th Hr. We're on a job right now — we'll text you in a moment."

3. Seconds later you get one text from our automated assistant about your call. By calling and hearing this message, you're asking us to text you back about your request.

Call-to-action shown to callers

Missed us? We'll text you right back. When you call 25th Hr and we can't answer, our automated assistant texts you from our business number to get the details of your job. Message frequency varies (typically fewer than 15 messages per request). Msg & data rates may apply. Reply STOP to opt out, HELP for help. See our Terms and Privacy Policy.

What the texts look like

• "Hi, this is the automated assistant for 25th Hr. Sorry we missed your call — we're on a job right now. What can we help you with? Reply STOP to opt out."
• "25th Hr: Thanks, [Name]. What's the address for the job, and is there a day that works best for someone to come take a look? Reply STOP to opt out."
• "25th Hr: Got it, [Name] — [job type] at [address]. The owner will call you back at this number to set up a visit. Reply STOP to opt out."

Stopping and help

• STOP (or UNSUBSCRIBE, CANCEL, END, QUIT) stops all texts from that number. You'll get one confirmation and nothing after.
• START (or YES, UNSTOP) opts you back in.
• HELP replies with who we are and how to reach us, or email rob@25thhr.ai.

We do not sell or share your SMS opt-in data or personal information with third parties for marketing purposes. Carriers are not liable for delayed or undelivered messages.
