Snagging an Interior: The Items Owners Sign Away at Handover

Interior defects hide in junctions, under lighting conditions nobody tested, and inside the difference between a defect and an incomplete item. These are the errors that lose them.

Snagging an interior is a different exercise from snagging a building. The items are small, numerous, concentrated at junctions and heavily dependent on the conditions you inspect in. Most of what gets missed is missed for one of three reasons: the inspection happened in the wrong light, the inspector did not know what had been specified, or a genuine defect was recorded as a preference and therefore never had to be corrected.

Why these keep happening

Handover happens under pressure from both sides. The installer wants release of money and the owner wants to occupy, so an inspection that should take a day happens in two hours, in daylight, with no furniture, no window treatments and no reference to the finishing schedule. Under those conditions an interior looks finished. The defects appear in the first fortnight of living in it, by which time payment has been released, the retention has gone and the trades have moved to the next job. The errors below are all about conditions and categories rather than about failing to notice obvious damage.

1. Inspecting in the wrong light

Paint and plaster defects appear under light grazing along a surface, so a wall that looks perfect under a ceiling light can be visibly uneven once a wall-washing fitting or a window at the right angle reveals it. Equally, lighting defects, glare and colour temperature mismatches only show at night. An inspection carried out once, at midday, with temporary lighting and no window treatments, cannot find either category.

• Avoid it by: Inspect each space twice: in daylight and again at night with the permanent lighting on and the window treatments fitted.
• Proof it is closed: The snag record shows two dated inspections per space, one of which was carried out at night.

What it costs you: Plaster and paint defects accepted permanently, plus lighting faults discovered after payment and treated as preferences.

2. Snagging without the finishing schedule in hand

An inspection carried out on appearance alone cannot detect a substitution. If the wrong tile, the wrong paint sheen, a different ironmongery suite or a substituted board has been installed, it looks like a finished interior rather than a defect. The only way to find it is to walk with the finishing schedule and the approved samples and compare line by line, which is slower and is the entire point of having produced those documents.

• Avoid it by: Carry the finishing schedule and the approved sample set, and check each room against its lines rather than against expectations.
• Proof it is closed: The snag record references schedule lines, and any discrepancy is recorded as a non-compliance rather than an observation.

What it costs you: Unapproved substitutions accepted as complete, with no basis to claim the difference in value afterwards.

3. Mixing defects, incomplete work and preferences in one list

The three categories carry entirely different consequences. A defect is non-compliance and must be corrected. Incomplete work is work that was contracted and not done, which affects whether completion can be certified at all. A preference is a change you want, which is a variation you will pay for. A single undifferentiated list lets the installer treat every item as negotiable, and the usual outcome is that genuine defects are closed by agreeing to accept some of them in exchange for the installer absorbing some of the preferences.

• Avoid it by: Keep three separate lists, labelled, and refuse to merge them during negotiation.
• Proof it is closed: Three distinct lists exist at handover and the certification of completion refers only to the defect and incomplete lists.

What it costs you: Genuine defects traded away in negotiation, and a weakened position on completion and on retention.

4. Recording items without a location, a photograph and a reference

An item recorded as scratch on wardrobe door cannot be found again by someone who was not present, which means it either does not get corrected or it gets argued about. Interior snagging produces hundreds of small items, and without a room reference, a position within the room, a photograph and a number, the list becomes unmanageable and items quietly disappear between revisions of the document.

• Avoid it by: Number every item with a room reference, a described position and a photograph taken at the time.
• Proof it is closed: Every open item has a number, a room reference, a photograph and a dated status, and the list is version controlled.

What it costs you: Items lost between list revisions, repeat site visits to identify defects and disputes about whether something was ever reported.

5. Inspecting an empty space rather than a furnished one

Several categories of defect only appear once the space is in use. Doors foul floor finishes once thresholds are fitted. Sockets turn out to be behind furniture. Joinery doors collide with handles and adjacent units. Curtain tracks interfere with door swings. Lighting glares from the position people actually sit in. An empty room hides all of it, and once furniture is in place the installer has a reasonable argument that the condition was caused by the furniture.

• Avoid it by: Where possible, inspect after the window treatments are fitted and with at least the principal furniture positioned.
• Proof it is closed: The inspection record notes which spaces were inspected furnished and which were not, with the reason.

What it costs you: Functional defects accepted because they were not visible at handover, with correction becoming the owner's cost.

6. Releasing retention before rectification is verified

Retention is the only leverage that survives handover, and it is routinely released on a promise that outstanding items will be dealt with. Once the money has gone, the incentive to return goes with it, and small items in particular never get closed. Equally, closing an item on the installer's word rather than on inspection means the correction may be cosmetic rather than real.

• Avoid it by: Release retention only against verified rectification, item by item, with a dated sign-off per item.
• Proof it is closed: Each closed item carries a verification date and the name of the person who inspected the correction.

What it costs you: An open snag list that never closes, and corrections that are superficial because nobody checked them.

7. Treating the handover file as paperwork rather than as a deliverable

The as-built finishing schedule, the product and batch records, the spares, the test certificates, the commissioning data and the warranties are what make the interior maintainable, and they are almost never produced unless their absence blocks payment. An interior handed over without them is one where every future repair is an approximation and several warranties are unenforceable because the registration or the installation record was never obtained.

• Avoid it by: Make the complete handover file a condition of final payment, checked against a list rather than accepted as a folder.
• Proof it is closed: A handover file checklist is signed off item by item before the final certificate is issued.

What it costs you: Unmatched repairs, lost warranty cover and maintenance carried out by guesswork in a building you paid to document.

A short check before you sign

• Confirm each space was inspected twice, including once at night with the permanent lighting and window treatments in place.
• Check that the inspection was carried out with the finishing schedule and approved samples in hand.
• Verify three separate lists exist for defects, incomplete work and preferences.
• Confirm every item carries a number, a room reference, a described position and a photograph.
• Check that retention release is tied to verified rectification item by item rather than to a general assurance.
• Run through the handover file checklist and confirm the as-built schedule, spares, certificates and warranties are all present.

If it has already happened

If money has already been released and items remain open, write to the installer with the numbered list, the photographs and the specification reference for each item, and set a date, because an undocumented complaint is easy to ignore and a documented one is not. Separate the items still within any defects liability or warranty period from those outside it, and pursue the first group through that mechanism rather than as a general grievance. For substitutions discovered after handover, the claim is usually about the difference in value rather than about replacement, which is frequently the more realistic remedy. Requirements and warranty conditions in this area change over time, so confirm the current position with the relevant authority and the product manufacturer, and take advice from a licensed legal adviser before withholding any further payment or pursuing a claim, since acting without a contractual basis tends to weaken your position.
