• CCTV Drain Surveys

    There are a multitude of reasons our customers would choose to have a CCTV drain survey and mapping carried out at their residential or commercial property. This can range from locating the root of an ongoing problem with a pipe, to planning what work can be carried out if they are intending to extend or renovate their commercial or residential property. It can be as simple as knowing how your drain system operates and where drains travel through and leave the building. 

    To help this process, Grey-Water Drainage offer a professional, accurate drain surveying and mapping service, so you will have a permanent record of the make-up and direction of your drains and also understand the current condition of your drainage system.

Why would you use a Drain CCTV Survey?

If you are looking to improve your home or business, or if you've ever wondered about the layout of the pipes on your residential or commercial property, we have the service to suit you.

Grey-Water Drainage will survey and map your drains, providing you with a schematic diagram of the site, showing all laterals and discharge points you can keep for years to come in the event of an issue, or if you're looking to extend your property.

Further Information
What's included in our drain mapping services?
When we provide our comprehensive site maps and diagrams and if you require DVD footage, they will detail every part of your property. This includes all inspection chambers, drain runs, lateral drains and invert levels. We will also be able to provide you with a condition report, and inform you of any damage that will need repairing.

If you would like this service carried out on your drain lines whether to discover a damaged pipe’s location causing a reoccurring issue or just to have a complete set of the drainage plans for your house or commercial property, get in touch with the Grey-Water team.
The Grey-Water Drain Mapping Process
When the Grey-water Team carry out a drain survey and mapping, we will use our flexible, state-of-the-art CCTV camera systems that will fit perfectly down your pipes to take clear and accurate footage of your drain lines.

This footage and any pictures taken are then recorded and will be available to you, before we provide advice on what to do to keep your drains running as they should and suggesting any repairs that may need to be undertaken.
Commercial Drain Mapping
If you own a business, there may be a time when your property is having building works carried out or you are building a new property, meaning you will benefit from having a map of the current drain lines and sewer connections, as these will have to be connected to any new or improved parts of your building. You may also have a new maintenance contract, or be experiencing problems such as continuing flooding on your industrial estate. 

Whatever the reason for your survey, we know that we can help carry it out quickly and smoothly, with little to no disruption to your daily routine. All Grey-Water engineers are fully qualified, CSCS certified, trained regularly in health and safety and well versed when it comes to site security, signing in and adhering to site rules. 

We understand your property is a professional environment with its own set of specific requirements, so we will do everything we can to keep to the standards you set. Call the Grey-Water team today and we can discuss what you need done on your property before you book your survey.

​Pre-Purchase Surveys

Pre-Purchase CCTV drainage footage is useful when weighing up the purchase of a property for
either commercial or residential. It is possible to uncover potential problems, to either negotiate a better price, pull out of the purchase, or even just to have confidence that the drainage system is problem-free. 

For a property buyer drain survey, a fully trained Grey-Water engineer will visit the property with the latest camera equipment to feed through the system to assess any obstructed or damaged pipes before compiling an industry standard drainage survey report.

Purchasing a new commercial or residential property is stressful enough without unforeseen and expensive drainage problems after your occupancy; our pre-purchase survey report will give you peace of mind.

Top Four Reasons to Undertake a Pre-Purchase Drain Survey:
  • Mortgages - Lenders may request a drain survey before agreeing to a loan, especially in areas with a history of drainage problems. Grey-Water Drainage pre-purchase drainage surveys are detailed and designed to meet industry standards. 
  • Identify issues to be resolved before a purchase - A CCTV camera inspection will flag any drainage issues before you become the homeowner and responsible for covering any costs.
  • Detailed drainage report - A generic property report won’t flag any drainage issues unless they are glaringly obvious and the inspector will not have the tools to access the drains and assess them.
  • Insurance - Some companies may not offer insurance on properties where drainage issues are found at a later date, while some insurers offer discounted rates on homes or properties where a drainage survey has been carried out and the drainage has proven to be faultless.

What are the Benefits of Pre-Purchase CCTV Survey?
The CCTV inspection survey itself involves investigating a property’s drainage as a whole but is not just useful for finding damage, ongoing or potential drainage issues. All of the information uncovered in the pre-purchase drain survey is useful to have during the purchase process, either to negotiate a better price, or to plan the works required ready to move into the property.
Pre-Purchase Report Information
The information compiled in a CCTV drainage report may help buyers and sellers get a property sale over the line, but Grey-Water Drainage will also compile useful insights into the drainage system.
Drainage System Responsibility
The CCTV drainage report will ascertain who is responsible for the drainage and sewage systems around the property, something not considered until a drainage problem such as a leak or blocked drain occurs. Much like a property boundary report, the insight from a CCTV drainage inspection will help you avoid confusion, neighbour disputes and legal problems.
Drain Mapping
Our pre-purchase drain survey will include a map of the drainage and sewage system, which will save the expense of investigating this if any urgent repairs are required. It’s also beneficial to have information from a CCTV drain mapping survey in case you sell the property in the future.
Detailed Reporting
Using our state-of-the-art drainage cameras, Grey-Water Drainage customers will receive a detailed CCTV survey report, inclusive of images and if requested video from the CCTV survey equipment. The details collated are useful to refer to when selling or purchasing a property and our engineers will be happy to explain any drainage faults and highlight the remedial work required.

Frequently Asked Questions

When should I have a survey carried out?

A drain inspection is usually carried out prior to a property renovation, acquisition or in the event of selling. This is done to ensure everything is in proper working order so that no new tenants or owners come across problems with the drainage, or to provide total peace of mind for anyone working, leasing or living in the property.

You may also need a survey undertaken if you're experiencing blocked drains and want to know the exact location of the blockage, or if you need a pipe relining and need the dimensions.

How long does a CCTV drain survey take?

Depending on the size of your property, a survey can vary when it comes to how long it will take to complete. We have been known to complete surveys in as little as an hour, but equally, a vast drainage system will need more time to assess, sometimes requiring more than one session. Small residential properties are often less time consuming than large office complexes, though there can be extenuating circumstances, such as blocked or broken drains that can require investigation.

How much does a CCTV drain survey cost?

The sum total of our surveys is dependent on the length of a session and the size of a property. It can also depend on the complexity of a drainage system, the accessibility of the drains, and where the property is situated logistically. Our surveys are generally provided from £75, with extra services being available to undertake, such as ground excavation and the inspection of large properties.

Do I have to pay in advance for a survey?

Due to previous experiences, we ask for payment in advance of a drain inspection report being provided.

Do I need a drain survey?

It may be pertinent to have a drain survey undertaken if you have moved into an old property or have been living in the same place for a few years without anything being done to your drains. Our experts are on call to help out and assess your drain system at a time that suits you. Give us a call to arrange an inspection by one of our local operatives.

Will a survey damage my drains?

Our surveys will never damage your drains. We use state-of-the-art drain survey equipment, handled by fully-trained professionals to assess the state and quality of your drainage system.

Are there local drain surveyors near me?

If you live in the Kent or London area, we have local operatives in your area. We are available to carry out commercial and residential drain surveys, depending on what you require. Give us a call and we will provide you with our next available visit date.

Can I carry out a CCTV drain survey myself?

Due to the specialist training and equipment needed in order to carry out a drain survey, only experts are qualified to undertake them. Talk to us today and find out how we can save you stress and money with our experienced staff.
