In this guide: the ten most common defects our inspectors find in UK new builds, with photos, and the steps to get each one fixed while it is still your developer's responsibility.

Introduction

Ever heard of snagging surveys and their importance in new build homes? These surveys highlight structural issues, plumbing and electrical faults as well as cosmetic issues that need to be addressed before they turn into costly repairs.

In this article, we explore the most common issues found in snagging surveys and share tips on how you can get them fixed and save thousands on costly repairs. A home is truly new when it is defect free.

When investing in a new build home in the UK, ensuring the property meets high-quality standards is more important than anything. A thorough snagging survey serves as your first line of defence against potential defects and building issues that could affect your home’s value and your living comfort. This guide explores the critical aspects of snagging surveys and the common issues they uncover in new build properties across the UK.

What is a Snagging Survey?

A snagging survey is a detailed inspection specifically designed for new build homes in the UK. It involves a comprehensive examination of every aspect of your new property to identify defects, incomplete work, or poor-quality finishes that need addressing before or shortly after moving in. These surveys are typically conducted by professional snaggers who understand building regulations and construction standards specific to the UK housing market.

Why are Snagging Surveys so Important?

The importance of snagging surveys for new build homes in the UK cannot be overlooked. A snagging survey protects your substantial investment by identifying issues early, when they’re still the builder’s responsibility to fix. Many new homeowners mistakenly assume that because their property is new, it will be perfect. However, the complex nature of modern construction means that hidden flaws and defects are common, even in premium developments.

Moreover, snagging surveys provide documented evidence of issues that might not become apparent until after your warranty period expires. This documentation can prove extremely useful when dealing with your builder. In the UK housing market, where new build homes often come with a 2-year NHQB warranty or similar guarantee, having a professional snagging inspection can safeguard your rights and ensure necessary repairs are completed.

Snag My New Home is the only company in the UK offering pre and post completion snagging inspections for ONE flat fee, for your complete peace of mind that you’ve got your property in the condition which should be expected from a brand-new home. How do we do it? We visit your property once and do a thorough inspection to find all the issues/snags, regardless of whether they fall into the pre or post completion inspection category. Once you receive the report, hand it over to your developer and let them decide which snags they would like to fix before completion and which ones after the completed purchase.

Most Common Issues Found in Snagging Surveys

Cosmetic Defects

Cosmetic issues are often the most immediately visible problems in new build homes. These include uneven paint finishes, marks on walls, poorly finished woodwork, and gaps in skirting boards. While these might seem minor, they indicate the overall attention to detail in your home’s construction. Professional snagging surveys frequently reveal:

  • Inconsistent paint coverage and visible brush marks
  • Gaps in decorative finishes around switches and sockets
  • Poorly fitted or damaged skirting boards and architraves
  • Uneven plasterwork and visible seams in wallboard joints

  • Settlement cracks in walls and ceilings
  • Uneven floor levels or springy floorboards
  • Inadequate foundation work
  • Problems with load-bearing walls
  • Issues with roof trusses and supports
