Truthful Communication & Approval Snippets
1-click text templates crafted to maintain client trust. Never start extra work without written confirmation.
Snippet 1: Honest Additional Work Notice
Send immediately when a client verbally asks for an extra task on-site.
“Hello [Client Name], regarding your request today to Install additional subfloor blocking and sistering: This is outside our initial agreed scope. The exact additional labor is 2.5 hrs at $50.00/hr and materials cost $100.00, totaling $225.00. No extra work will begin until you review and confirm this adjustment. Please reply with your approval if you would like us to proceed.”
Snippet 2: Discovered Hidden Defect Notification
Send when non-visible rot, plumbing leaks, or electrical hazards are uncovered.
“During surface prep in [Area], we discovered an existing underlying issue: [Describe issue, e.g., compromised subfloor/pipe]. We have paused work on this specific area to show you the condition in person or via photo. We will provide an exact cost breakdown for repair before doing any further work.”
Snippet 3: Daily Zero-Surprise Scope Summary
Send as a daily reassurance log so the client knows their invoice matches the original quote.
“Hello [Client Name], here is our daily job log for [Date]. All tasks performed today fall 100% within our initial agreed scope at $0.00 additional charge. Any future adjustments will be presented in writing before beginning.”
The 4 Ethical Rules of Field Contracting
Non-negotiable operational standards that separate respected tradespeople from contentious dispute-plagued contractors.
Prior Written Disclosure
“Never bill a client for extra work they did not explicitly approve in advance.”
Always pause work and secure digital approval (SMS, email, or signed digital change order) specifying the exact dollar impact before picking up tools.
Transparent Material Accounting
“Clearly distinguish labor charges from physical material retail receipts.”
Provide transparent direct material receipts or agreed unit pricing. If charging a handling/delivery fee, declare it openly rather than hiding a 40% markup inside labor rates.
Documented Defect Proof
“Always take timestamped photos of hidden damage before touching it.”
When uncovering rotted subfloors or severed conduit, take clear wide-angle and close-up photos with a tape measure showing scale. Share with the homeowner before demolition.
Immediate Written Clarity
“Replace verbal hallway conversations with clear, written summaries.”
Casual conversations like 'Sure, can you do that wall too?' must immediately be followed by a 2-sentence confirmation text with time and cost before mobilization.
