By the end of an extension project, everyone involved is usually keen to get the last details finished and move on. That is exactly when small defects, incomplete finishes and awkward details can be missed. If you have been watching the build develop for months, it can also become difficult to notice issues objectively.
An extension snagging inspection provides an independent visual review of the completed or nearly completed work. An independent snagging survey provider can inspect accessible areas, identify visible defects and help you create a clear record of items to discuss with your builder before the project is fully closed out.
The exact inspection depends on the type of extension and the work completed. The inspection can focus on the visible quality and condition of accessible elements rather than replacing specialist certification or statutory inspections.
An independent snagging survey provider can inspect walls, ceilings, paintwork and other visible surfaces for damage, patchy finishes and incomplete work.
Accessible doors, trims, skirting, fitted joinery and similar elements are checked for obvious defects and finishing issues.
Visible flooring, tiling and junctions are reviewed for damage, poor finishing and incomplete details.
Where the extension includes fitted units, an independent snagging survey provider can inspect accessible finishes and fittings for visible defects or poor adjustment.
Where safely accessible, relevant external finishing associated with the extension can be included in the visual inspection.
| Service | Estimated Cost | Average |
|---|---|---|
| Small single-room extension | £250–£350 | Around £300 |
| Typical kitchen or rear extension | £300–£450 | Around £375 |
| Large or complex extension | £400–£600+ | Around £500 |
These figures are general estimates. The final fee depends on extension size, complexity, location, accessibility and the scope of the inspection.
An independent inspection can give you a fresh view of work you may have been looking at every day throughout the build.
Observed snags are brought together so you can discuss finishing work with your contractor more clearly.
The inspection concentrates on visible workmanship and finishing issues at the point where the project should feel complete.
If your extension is approaching completion, tell us what has been built and when the final handover is expected.
Free enquiry — no obligation
Explain the size and type of extension, where you are in the build and when the contractor expects to finish.
The most useful inspection is normally when the work is substantially complete but before every final item has been signed off.
An independent snagging survey provider can review accessible areas and record visible defects, poor finishes and incomplete details.
Use the findings as a practical reference when agreeing what still needs to be corrected.
