When Should You Do A Snagging Inspection? Before or After Completion?

Learn when to carry out a snagging inspection on your new-build home, whether you should inspect before or after completion, and how to spot defects early.

Buying a new-build home is undeniably exciting, but it's also one of the biggest financial commitments most of us will ever make. By the time you receive your completion date, it's easy to assume everything has been finished to a high standard and is ready to move into.

Unfortunately, the reality is that the majority of brand new homes will contain defects.

From cosmetic issues like paintwork and damaged fixtures to more significant problems such as poorly fitted doors, uneven flooring, or faulty electrical sockets, most new-build properties will have some level of snagging.

One of the most common questions new or inexperienced buyers ask is:

When is the best time to carry out a snagging inspection?

The answer depends on where you are in the buying process, but in most cases, the earlier you can identify issues, the better.

What is a Snagging Inspection?

A snagging inspection is a detailed review of your new-build property designed to identify defects, unfinished work, or areas that don't meet the expected standard.

The goal is to create a snagging list that can be shared with your developer so issues can be corrected.

Common snagging issues include:

  • Paintwork defects
  • Damaged kitchen units
  • Cracked tiles
  • Poorly aligned doors
  • Scratched windows
  • Faulty sockets and switches
  • Gaps around fixtures and fittings
  • Uneven flooring

Even homes built by the most reputable developers can contain snags, which is why inspections are considered a normal part of the new-build buying process.

The Best Time to Carry Out a Snagging Inspection

Ideally, you should inspect the property before legal completion.

This gives you the opportunity to identify defects before moving in and allows the developer to address issues before the home becomes occupied.

Many developers offer a pre-completion home demonstration, home tour, or handover appointment. This is often your first opportunity to walk through the property in detail.

If you're given access before completion, use the opportunity wisely.

  • Take your time
  • Open every door
  • Test every window
  • Check every room carefully
  • Document anything that appears unfinished, damaged or poorly installed

The earlier defects are identified, the easier they are usually to resolve.

What If You Can't Inspect Before Completion?

Not every buyer is given access prior to legal completion. In some developments, you may only receive access on the day that you collect the keys.

If this happens, don't go into panic mode. You can - and should - still carry out a snagging inspection as soon as possible after picking up the keys. A lot of homeowners actually discover issues organically during their first few days of occupancy simply by living in and using the property.

These issues can include:

  • Heating issues
  • Leaking pipework
  • Doors that stick or don't fit frames properly
  • Faulty appliances
  • Poor drainage
  • Electrical problems

It's common to continue to find defects and snagging items for a number of weeks after moving in. The important thing is to record issues as soon as they are discovered and report them promptly with a structured report.

Should You Carry Out More Than One Inspection?

Yes. Sometimes the short and sweet answers are the best.

Many buyers assume snagging is a one-time activity, but the most effective approach is to carry out several inspections over time.

Inspection 1: Pre-Completion Walkthrough

This is your first opportunity to identify obvious defects and unfinished work. Focus on:

  • Decoration
  • Fixtures and fittings
  • Flooring
  • Doors and windows
  • Kitchen and bathroom installation

Inspection 2: Moving-In Inspection

Once you have access to the property, test everything thoroughly.

  • Use appliances that come with the property
  • Run taps and showers. Ensure water gets hot and water pressure is sufficient
  • Check heating systems
  • Test every socket and light switch

Many defects only become apparent once the home is being actively used and lived in.

Inspection 3: End of Defects Liability Period

Most developers provide a period during which snagging issues can be reported and corrected.

Before this period ends, conduct another thorough inspection and raise any outstanding concerns. This gives you the best chance of ensuring issues are addressed while the developer remains responsible.

How Long Should You Spend on a Snagging Inspection?

A proper snagging inspection should never be rushed.

For an average three-bedroom home, it's not unusual to spend between two and four hours inspecting the property thoroughly. Larger homes may require significantly longer.

The biggest mistake buyers make is focusing only on visible defects. Take the time to:

  • Open every window and test window locks
  • Lock and unlock every door
  • Test every socket
  • Check all appliances
  • Inspect flooring carefully
  • Look for damage to walls and ceilings
  • Examine sealant around bathrooms and kitchens

Small issues can be easy to miss when you're distracted by the excitement of collecting your keys.

What Happens If You Find Lots of Defects?

Finding dozens of snagging issues can feel alarming, especially if you've just purchased a brand-new home. The reality is that most new-build properties will have some level of snagging and it's best to be prepared for that to be the case.

Did you know?

One professional snagging company, Next Step Snagging, identifies 150 - 250 items per snagging inspection.

A long snagging list does not necessarily mean the property has been poorly built. Many items are often cosmetic or minor finishing issues.

What's more important is:

  • Recording defects early
  • Taking photographs
  • Providing precise locations
  • Reporting issues promptly
  • Keeping track od developer responses

Good documentation makes the resolution process much smoother.

Professional Snagging Inspection vs DIY

Many buyers choose to inspect the property themselves. This could be down to cost of hiring a professional or the excitement of actually wanting to be part of the process.

Others prefer to hire a professional snagging surveyor.

A professional inspection can identify issues that homeowners may overlook, particularly around workmanship, building standards, and technical defects. Professionals can also offer additional services such as thermal imaging and cavity wall inspection.

However, even if you use a professional surveyor, it's still worth carrying out your own inspections after moving in.

You'll often notice practical day-to-day issues that wouldn't necessarily be apparent during a single visit.

Final Thoughts

The best time to carry out a snagging inspection is as early as possible, ideally before completion and again shortly after moving in.

New-build homes are rarely perfect, and even minor defects can become frustrating if they're not identified and reported quickly.

Take your time, inspect thoroughly, and keep detailed records of any issues you find.

A well-documented snagging list gives you the best chance of ensuring issues are resolved quickly, helping you enjoy your new home with confidence.
