Snagging is the process of inspecting a newly built or renovated property for defects, unfinished work, damage or incorrectly fitted items so they can be corrected by the developer or contractor. Each individual problem is called a snag, while the full record is a snagging list or snagging report.

In the UK, new-build warranties commonly include an initial builder responsibility period of around two years, although the exact terms vary. Reviewed:

In the United States, the equivalent construction term is usually punch list or punch-list inspection.

What Does Snagging Identify?

Snagging identifies cosmetic defects, unfinished work and problems that affect how a property functions, performs or lasts.

Common examples include:

  • Poor paint, plaster or flooring finishes
  • Cracked tiles or damaged fixtures
  • Doors or windows that do not close properly
  • Loose handles, hinges, sockets or light switches
  • Leaking taps, pipes or radiators
  • Faulty heating, ventilation or hot water
  • Missing sealant around sinks, baths and windows
  • Incomplete kitchen or bathroom fittings
  • Incorrectly installed appliances
  • Damaged walls, flooring, cupboards or worktops
  • Missing items listed in the property specification
  • Problems with external paving, fencing, drainage or landscaping

A snag does not have to be visible. A heating system that does not work correctly is a snag. So is a window that allows water to enter the property.

When Should Snagging Take Place?

Snagging should ideally take place after construction is substantially complete but before legal completion and handover. The developer then has an opportunity to correct problems before you move in.

GOV.UK recommends considering a snagging survey once the property has been built and before completion.

You can inspect the property again after moving in because some problems only appear during normal use. For example:

  • Regular use may reveal faults with heating and plumbing.
  • Connecting appliances may expose electrical or installation problems.
  • Doors and windows can expand or contract.
  • Heavy rain may reveal leaks or drainage issues.
  • Occupying the property may expose problems that were not apparent during an empty inspection.

Who Carries Out a Snagging Inspection?

The buyer or an independent snagging company can carry out a snagging inspection. GOV.UK recognises both options.

A professional inspector may be useful if you:

  • Have limited experience checking construction work
  • Cannot attend the property yourself
  • Are buying a large or complex new-build home
  • Want a formal report to send to the developer
  • Need someone to inspect areas that are difficult to access

If you inspect the property yourself, work through it systematically, room by room. Test utilities where possible, take clear photographs and record the exact location of each issue.

Do not combine unrelated defects into one entry. A loose door handle and a cracked bathroom tile should be listed separately, even if they are in the same room.

How Does the Snagging Process Work?

The snagging process involves inspecting the property, recording each problem, reporting it and checking the work after the developer or contractor responds.

A practical process is:

  1. Inspect the property inside and outside.
  2. Record each issue separately.
  3. Take photographs or video that show the defect clearly.
  4. Describe the required remedy, such as repainting, resealing or replacing a damaged fitting.
  5. Send the snagging list to the developer or contractor in writing.
  6. Agree access arrangements and expected completion dates.
  7. Inspect the property again after the work is reported as complete.
  8. Keep evidence of unresolved items, including emails, photographs and appointment records.

A useful snagging report states the location, problem, priority and required action. For example:

Bedroom 2, east-facing window: the window handle is loose and the sash does not close fully. Adjust or replace the handle and confirm that the window locks correctly.

The report should make it clear what needs to be fixed. "Window problem" is less useful than a description that identifies the room, the part affected and the expected repair.

Is Snagging the Same as a Home Survey?

No. A snagging inspection focuses mainly on workmanship, unfinished items and defects in a newly built property. A home survey assesses the overall condition of a property and may identify broader maintenance or structural concerns.

A mortgage valuation is different again. GOV.UK states that a mortgage valuation is not a home survey and may not provide a detailed assessment of the property's condition.

For a new-build purchase, a buyer may consider both:

  • A home survey for the property's general condition
  • A snagging inspection for finishing quality and incomplete work

A snagging inspection does not replace legal checks, planning checks or an appropriate home survey.

Who Pays for Snagging Repairs?

The developer or contractor will normally be asked to correct defects caused by incomplete, damaged or substandard work. Responsibility depends on the purchase contract, the developer's obligations and the applicable home warranty.

In the UK, many new-build warranties have an initial builder responsibility period, commonly around two years, followed by longer-term cover for certain major defects. Warranty terms vary, so check what is covered, when problems must be reported and which exclusions apply.

A warranty may not cover:

  • Damage caused by the homeowner
  • Normal wear and tear
  • Poor maintenance
  • Items outside the home or warranty boundary
  • Cosmetic issues below the warranty provider's tolerance levels
  • Alterations carried out after completion

The contract and warranty documents should be checked before deciding who is responsible for a repair.

What Should You Do If the Developer Does Not Fix the Snags?

If the developer does not fix a reported snag, keep the complaint in writing and follow the relevant contract and warranty process.

The usual steps are:

  1. Check the purchase contract and warranty documents.
  2. Submit a formal complaint to the developer.
  3. Contact the warranty provider if the developer does not resolve the problem.
  4. Use any applicable consumer code or dispute-resolution process.
  5. Seek legal advice if the problem is serious or affects safety, habitability or significant value.

Local guidance in the UK generally recommends contacting the builder first, followed by the relevant home warranty provider if the issue remains unresolved.

Keep copies of the snagging list, photographs, emails, inspection notes and appointment records. This gives you a clear record of what was reported and what remains outstanding.

Why Is Snagging Important?

Snagging matters because defects are easier to report and follow up when they are recorded clearly and inspected while the property is still under the developer's responsibility.

A proper snagging list helps you:

  • Identify unfinished or faulty work
  • Explain exactly what needs to be corrected
  • Track repairs over time
  • Check whether reported work has actually been completed
  • Keep evidence if a dispute develops

Arrange the inspection before completion where possible, report the findings in writing and inspect the property again after remedial work. That process gives you the clearest record of the property's condition and the repairs requested.
