Email is still the backbone of day-to-day communication on a jobsite. Whether you are pushing a revised framing schedule to subs or sharing a stamped plan with the building department, files have to move fast. Hit the Comcast attachment size limit, however, and the workflow slams to a halt. For residential contractors juggling dozens of RFIs, change orders and homeowner updates, every minute wrestling with a bounced email is time stolen from the build itself.
The current Comcast attachment size limit for outgoing messages is 25 MB. Anything larger will be rejected or automatically truncated. A single high-resolution PDF plan set or a batch of jobsite photos can easily exceed that threshold. When field supervisors and office staff are unaware of the cap, critical information ends up stuck in an outbox, causing delays that ripple through trade partners and inspectors.
Key takeaways for contractors:
• The 25 MB ceiling includes the email body, headers and metadata, so your “actual” file room is even smaller.
• Compressed ZIP folders count as one attachment. If the ZIP exceeds 25 MB, the message still fails.
• Many municipalities mirror the same limit, so forwarding a large plan set may bounce twice—first from Comcast, then from the city’s server.
• Lost bid opportunities when architectural drawings never reach the estimating department.
• Field delays because updated truss calcs don’t arrive before the crane is scheduled.
• Frustrated homeowners who wonder why progress photos stop mid-project.
• Duplicate data entry as crews try multiple cloud links and versions of the same file.
• Security risk from unsanctioned file-sharing apps used to “work around” the limit.
CountBricks was built by builders, for builders. Instead of forcing your files through the Comcast attachment size limit, we bypass it entirely.
• Real-time voice-to-estimate engine converts onsite conversations into lightweight PDFs under 1 MB, perfect for instant emailing.
• AI blueprint takeoffs run in the cloud. Upload a 300 MB plan set to CountBricks.com/services and our engine returns a full material schedule while you’re still in the driveway—no file ever travels through Comcast’s 25 MB gate.
• Branded proposal generator stores high-resolution imagery on our secure servers and embeds view-only thumbnails inside the email. Your client clicks once to open the complete gallery without a single attachment.
• Automatic version control means you email a link, not the file. Everyone sees the latest framing detail, even if it changed after you pressed “send.”

• Unlimited cloud storage tied to each project so all stakeholders pull from a single source of truth.
• Instant quote generation that reduces multi-megabyte spreadsheets to simple, branded PDFs.
• Digitally signed change orders delivered through secure links rather than bulky attachments.

Cedar Ridge Homes, a custom builder in the Pacific Northwest, struggled with the Comcast attachment size limit during a 5,800 sq ft lakefront build. The architectural firm issued weekly revisions that averaged 38 MB per PDF. Each bounced email generated hours of back-and-forth phone calls, pushing framing four days behind.
• Our onboarding team imported the entire drawing set into the CountBricks cloud within one hour.
• Using AI blueprint takeoffs, we produced a detailed lumber schedule and cost code breakdown, trimming two estimating days.
• Share links replaced attachments. The superintendent texted a single URL to the truss fabricator, who opened the file onsite without Wi-Fi.
• Zero bounced emails for the remainder of the project.
• Four-day schedule recovery, allowing cabinetry to install on the original date.
• 11 % cost savings on framing lumber captured through rapid material reconciliation inside CountBricks.com/services.
• Audit common outgoing files—if they edge close to 20 MB, switch to secure links before the problem starts.
• Empower field staff with the CountBricks mobile app so photos upload directly to the cloud instead of email threads.
• Standardize proposal templates generated by CountBricks. They stay under 1 MB, maintaining professional branding without flirting with the Comcast attachment size limit.
