Construction Snag List Template

A snag list (or snagging list) is the record of defects, incomplete work, and minor issues that need to be resolved before a construction project can be considered complete. Getting snagging right is critical - it directly affects client satisfaction, retention payments, and your reputation. This guide provides a practical template and advice for managing snags efficiently.

What Is a Snag List?

A snag list is a document that records every defect, incomplete item, or quality issue identified during inspection of completed or near-complete work. In other countries it is called a punch list or defects list.

Snags typically fall into three categories:

• Defective work - work that does not meet the specification or acceptable quality standards
• Incomplete work - items that have not been finished
• Damage - work that was completed satisfactorily but has been damaged by subsequent trades or activities

The snag list drives the final phase of a project, ensuring everything is resolved before practical completion and handover to the client.

When to Start Snagging

The best site managers do not wait until the end of the project to start snagging. They operate a rolling snagging process throughout the build:

• During construction - inspect work as each trade completes their section. Fix issues while the trade is still on site, not months later when they have moved on.
• Pre-completion inspection - a thorough walk-through 2-4 weeks before the planned completion date. This is your main snagging exercise.
• Client walk-through - the client (or their representative) conducts their own inspection and adds items to the list.
• Post-handover - defects that emerge during the defects liability period (typically 12 months).

The earlier you catch snags, the easier and cheaper they are to fix. A paint defect found while the painter is still on site costs nothing to resolve. The same defect found six months later requires mobilising a painter back to site, touching up, and possibly redecorating entire rooms.

Snag List Template

Each snag item should record:

• Reference number - unique ID for tracking
• Date identified
• Location - building, floor, room, and specific location within the room
• Description - clear, specific description of the issue
• Category - defect, incomplete, damage
• Trade responsible
• Subcontractor - company responsible for rectification
• Priority - critical, major, minor
• Photo - always attach a photo. It removes ambiguity.
• Target completion date
• Status - open, in progress, completed, verified
• Date completed
• Verified by - who checked the rectification

Common Snag Categories

Decorations

Paint runs, missed spots, brush marks, uneven coverage, paint on frames or glass, poor cutting in at edges. Decorating snags are the most common category on most projects.

Joinery

Doors not closing properly, gaps at frames, scratches on timber, ironmongery not aligned, drawer runners stiff, kitchen units not level.

Plumbing

Dripping taps, slow drains, toilets not flushing correctly, silicone sealant issues, radiators not heating evenly, exposed pipework.

Electrical

Switches not working, lights flickering, sockets loose, missing cover plates, uneven switch alignment, smoke detectors not tested.

Tiling

Lippage between tiles, grout cracking, uneven cuts, hollow tiles (tap test), silicone discolouration.

External

Pointing defects, damaged render, incomplete landscaping, drainage issues, paving settlement.

Managing the Process

• Be systematic - work through each room methodically. Use a consistent route: ceiling, walls, floor, doors, windows, services.
• Be specific - "paint issue in bedroom 2" is not helpful. "Roller marks on north wall of bedroom 2, 1.5m from floor level" is.
• Assign responsibility - every snag must have a named subcontractor responsible for fixing it
• Set deadlines - give each subcontractor a clear date for completion. Follow up on the day, not a week later.
• Verify rectification - do not close a snag until you have personally inspected the fix. A snag closed without verification is likely to reappear.
• Track progress - maintain a running count of open vs closed snags. Report this to the project team weekly.

Closing Out Snags

The goal is to have every snag resolved before practical completion. In practice, a small number of minor items may remain on a schedule of outstanding works, but the fewer the better.

Common reasons snag lists drag on:

• Subcontractors not returning to complete work (use retention payments as leverage)
• Fixes creating new damage (ensure adequate protection of completed areas)
• Access issues (the building may be partially occupied)
• New snags being identified faster than old ones are resolved

Be firm but fair. Subcontractors should fix genuine defects at their cost. But if the issue is caused by another trade damaging their work, that is a different conversation.

Digital Snagging

Paper snagging lists are inefficient. Digital tools offer:

• Photo integration - snap a photo and attach it to the snag instantly
• Pin-drop on plans - mark the exact location on a floor plan
• Automatic notifications - subcontractors receive their snag items instantly
• Real-time tracking - see the status of every snag across the project
• Reporting - generate snag reports for the client in seconds

Final Thoughts

Snagging is not glamorous, but it is the last impression you leave on a client. A project delivered with a clean snag list builds your reputation and leads to repeat business. A project handed over with hundreds of unresolved snags damages relationships and costs money. Invest the time in getting it right.
