Most Common New Build Snags: What Buyers Should Look For

A new build snag is a defect, unfinished item or quality issue identified in a newly built home. Some are cosmetic and straightforward to correct. Others can affect how the home works and deserve quicker investigation.

There is no single snagging list that applies to every property, and a long list does not automatically mean a house is badly built. The aim is to check the home methodically, record anything that needs attention and distinguish minor finishing issues from defects that may need specialist assessment.

The areas below are among the most useful places for new build buyers to check. They are not ranked by frequency.

Paintwork, plaster and decorating

Decorative finishes are some of the easiest snags to spot.

Look for:

• uneven paint coverage

• chips, scratches or marks

• rough plaster finishes

• visible filler

• poor joins around skirting and architraves

• cracked or incomplete sealant

• paint on sockets, hinges or fittings

Small cosmetic defects are usually easier to resolve when they are photographed and reported clearly.

Fine shrinkage cracks can also appear as a new home dries. Our guide to new build cracks and settlement explains when cracking may be normal and when it deserves closer attention.

Doors, frames and ironmongery

Open and close every accessible internal and external door.

Check that:

• doors move freely

• handles and locks work

• doors do not catch excessively on floors or frames

• frames look square

• hinges are secure

• fire doors, where fitted, have not been altered or damaged

• external doors seal properly

A stiff door can be a simple adjustment issue, but repeated movement or doors suddenly becoming difficult to close can also be worth recording if other signs of movement are present.

Windows and glazing

Check each window you are permitted to operate.

Look for:

• scratches or damaged glass

• damaged frames

• missing or poor sealant

• handles and locks that do not work

• windows that do not close properly

• draughts around frames

• visible gaps

• trickle vents that are missing, blocked or difficult to operate where they form part of the ventilation design

Condensation can occur while a new home dries, but persistent moisture and mould should not simply be dismissed. See our guide to new build condensation and mould.

Kitchens

A kitchen contains many moving parts and finished surfaces, so check it carefully.

Look at:

• cupboard and drawer alignment

• doors that rub or do not close

• damaged worktops

• worktop joins

• sealant around sinks

• taps

• visible pipework beneath sinks

• appliances included in the specification

• extractor operation

• sockets and switches

• obvious leaks

Confirm that the actual kitchen matches the written specification for the plot rather than assuming everything seen in the show home is standard.

Bathrooms and plumbing

Check visible finishes and fittings around bathrooms, en-suites and WCs.

Look for:

• chipped sanitaryware

• loose fittings

• poor grout or sealant

• visible leaks

• slow drainage

• loose shower screens

• damaged tiles

• taps that do not operate correctly

• extractor fans that do not appear to run

Do not dismantle fittings or attempt electrical or plumbing repairs yourself during a snagging inspection.

Flooring, stairs and joinery

Walk through each room and notice whether anything feels loose, uneven or incomplete.

Check:

• damaged flooring

• lifting edges

• obvious gaps

• loose stair components

• damaged skirting

• rough joinery

• loose handrails

• unfinished cupboards

Minor gaps can occur as timber and other materials dry, but significant movement should be reported.

Heating, ventilation and controls

Make sure you receive instructions for the systems installed in the home.

Check accessible controls for:

• heating

• thermostats

• hot water

• extractor fans

• mechanical ventilation

• heat recovery systems where fitted

Modern new homes rely on ventilation systems to control moisture and indoor air quality. Do not permanently close vents or switch off systems you do not understand; ask the developer to explain how they should be used.

External brickwork, render and finishes

Walk around the exterior where it is safe and permitted.

Look for:

• damaged bricks

• poor or incomplete pointing

• cracks

• unfinished render

• loose or incomplete trims

• gaps around penetrations

• damaged sills

• unfinished external paintwork

Do not attempt to inspect roofs or other areas requiring ladders unless you are suitably qualified and equipped.

Guttering, downpipes and visible drainage

NHBC's homeowner checklist specifically encourages buyers to look at external pipes and drainage.

Check whether:

• gutters and downpipes appear secure

• there are visible leaks

• outlets appear blocked

• manhole covers sit properly

• water is being discharged somewhere sensible

• ground levels appear to direct water towards rather than away from the building

If the garden repeatedly holds water after normal rainfall, read our guide to new build garden drainage problems.

Gardens, boundaries and landscaping

The garden can be overlooked because buyers naturally focus on the house.

Check:

• fences and gates

• plot boundaries

• turf and landscaping included in the specification

• builders' debris

• obvious depressions

• waterlogging

• retaining walls

• paving

• paths and steps

• access to drains and inspection covers

Photograph the garden before changing levels or landscaping because later alterations can make it harder to establish what was originally provided.

Garages, parking and external areas

Check that the property you receive matches the agreed plan.

Look at:

• allocated parking

• garage doors

• drives

• pathways

• external lighting

• electric vehicle charging equipment where included

• bin storage

• communal areas immediately affecting the plot

If something shown in the reservation documents is missing or materially different, raise it with the developer and your conveyancer as appropriate.

Noise and sound insulation

Some everyday noise will always travel through a home, particularly in attached houses and flats.

However, if noise transmission seems unusually intrusive, document where it comes from, what type of sound it is and when it occurs.

Our guide to new build soundproofing problems explains what Building Regulations in England say about resistance to sound and when specialist acoustic advice may help.

How should you record new build snags?

A useful snagging list should be easy for someone else to understand.

For each issue:

• Give it a number.

• State the room or external location.

• Describe the defect briefly.

• Add a clear photograph.

• Note whether it prevents normal use.

• Record when it was reported.

• Keep the developer's response.

Avoid vague entries such as "bathroom bad". A description such as "sealant missing along rear edge of bath beside shower screen" is much easier to action.

Should you use a professional snagging inspector?

You can inspect a new home yourself, but a specialist can provide an independent and more systematic inspection.

Our guide is a snagging survey worth it? explains the pros and limitations.

If you want to compare firms, use the UK snagging company directory to find independent inspectors covering your area.

What happens after you send the snagging list?

Use the developer's recognised after-sales process and keep records.

For homes covered by the New Homes Quality Code, developers must provide after-sales support and deal with snags as part of that service. The exact rights available to you depend on the developer, reservation date, warranty and consumer code applying to your home.

If repairs stall, read what happens if a developer won't fix snags.

Research build quality before you reserve

A snagging inspection happens near completion, but research should begin much earlier.

Compare the housebuilder's published customer satisfaction data, third-party review themes and aftercare reputation before choosing a plot.

Browse new build developers or see the latest new build developer rankings.

A national score cannot predict the condition of one house, but repeated themes around handover, snagging and aftercare can provide useful context.

The bottom line

The most useful snagging checklist is not the longest one. It is the one that checks the whole home methodically and records defects clearly.

Pay attention to finishes, doors, windows, plumbing, ventilation, external works, drainage and gardens as well as the obvious cosmetic details.

Report problems promptly, keep evidence and get professional help where an issue appears more significant than a routine finishing snag.
