Useful information on home buyer drain surveys


Here are some frequently asked questions about home buyer drain surveys:

What is a home buyers' drain survey?

A home buyers' drain survey is an in-depth inspection of the drainage system for a property, prior to a home buyer purchasing it. It is conducted using CCTV cameras which are navigated throughout the network, to identify any potential problems which may arise. 


The key elements of a home buyer’s drain survey involve the following:


Inspection of the drainage system

A detailed examination of the whole system will be undertaken by one of our knowledgeable engineers. Specialist equipment is used to review the condition of the pipes, drains and sewers.


Identification of faults

The primary purpose of a home buyers' drain survey is to identify any potential problems or hazards within the system, with the aim to get them rectified. Issues may include blockages, leaks, cracks, faulty pipes, tree root intrusion and other damages. Finding these things early can prevent costly repairs if left undetected. It can also help the home buyer make an informed decision regarding the overall condition of the property. 


Full report provided 

Once the examination is complete, our engineers will complete a full report with details of the condition of the drain, including any advisory works required. This report provides information about the current state of the drainage system, any identified problems, and recommendations for necessary repairs or maintenance.


Negotiation tool

An important part of the home buyer’s drainage survey is providing a negotiation tool for those looking to purchase a new property. If significant drainage issues are discovered, the buyer can discuss possible solutions with the seller, such as repairs or adjustments to the sale price.


What are the benefits of a home buyers' drain survey?

A home buyers' drain survey, also known as a pre-purchase drain survey or drainage inspection, involves an extensive review and assessment of the drainage system of a property before a potential buyer decides to purchase. 


Firstly, a home buyers' drain survey helps to identify any pre-existing problems with the system, which may cause issues for the potential buyer. This can include occurrences such as blockages, leaks, cracks, or structural damage. Addressing potential problems early on can avoid major disruptions including health hazards from progressing prior to moving in. These could be a result of blocked or damaged drains.


A drain survey will ensure the drainage system is functioning properly, and give new home buyers' peace of mind. It allows the buyers to make an informed decision regarding the purchase of the property. 


Identifying potential drainage problems prior to moving into a new property can save money in the long run. If early signs of blockages or malfunctions are detected, they can be fixed before they progress to a more disruptive level. Drain surveys provide leverage for buyers, if issues within the system have been found. They can negotiate to have the necessary repairs done, or alter the sale price of the property. 


Another key reason to have a home buyer drain survey conducted is that it provides evidence of sufficient maintenance to insurers. This ensures that the property is fully insured, and proof is obtained as to the quality of the drainage system. In addition, it could help home buyers to secure a better insurance rate. The report will also provide evidence of compliance with local rules and regulations. 


Our home buyer drain surveys are conducted by our trained professionals, who know exactly what to look out for when it comes to underground drainage systems. Specialist equipment is used, including CCTV drain cameras, to get a comprehensive understanding of the condition of the drain. This ensures that the most effective inspection methods are observed, to obtain the most accurate information. Significantly more detail can be found using this method, as opposed to a simple visual inspection.
