Why Drain Surveys Are Essential Before Building a Garden Room or Annex in Derby
Garden rooms, annexes, and outdoor offices are becoming increasingly popular in Derby, Burton, Hilton, and the wider Midlands. They add value, comfort, and space to your property. However, many homeowners overlook one crucial step before construction — checking the existing drainage system. Building near or over drains without inspection can cause serious problems, including structural damage, blockages, or even planning rejections from Severn Trent Water or the local authority.
A CCTV drain survey identifies the location, layout, and condition of your drains, ensuring your new build complies with regulations and avoids costly disruptions.
Common Drainage Problems That Affect Garden Builds
Before construction begins, it is vital to understand potential issues that can impact your project:
Cracked or collapsed drains beneath or near the foundation area
Tree root intrusion affecting underground pipework
Blocked or misaligned joints causing poor drainage
Drains too close to proposed structures, risking long-term damage
Rodent access points that may lead to infestations once construction begins
Identifying and resolving these problems early ensures that your project remains compliant, safe, and on schedule.
Why a CCTV Drain Survey Is Essential
A CCTV drain survey provides an in-depth look at the condition and position of your underground drainage. This professional inspection ensures that no part of your garden room or annex build interferes with existing drains. Benefits include:
Accurate mapping of drain routes and connections
HD video footage showing the condition of pipes and joints
Clear written reports suitable for planning or building control approval
Expert recommendations for treatment or preventive maintenance
This proactive approach prevents expensive delays and ensures your garden build is fully compliant with drainage regulations.
Practitioner-Focused Treatments
Once a survey is complete, the following treatments may be recommended:
Pipe Relining to repair cracks or weak spots without excavation
Joint Repair to strengthen displaced or misaligned pipe connections
Root Removal to eliminate blockages and protect pipe structure
Rodent Proofing to prevent entry points that lead to infestations
Preventive Maintenance to maintain flow and prevent future issues
Each treatment protects your investment, ensures drainage efficiency, and allows your garden room or annex to be built with confidence.
