Choose BN Drainage for a pre-purchase drainage survey, and find out what’s going on in your pipes

 

Pre-Purchase Drain Survey for Homebuyers

We believe that nobody should commit to purchasing a property without first receiving a drain homebuyer’s report. Without a pre-purchase drain survey having taken place, you will be unaware if there are any problems with the drainage system at the property. Our specialist engineers can perform a thorough inspection of the drains before you make any final decisions, and they will also give you any expert advice they feel is relevant. Trust us to carry out a pre-purchase drain survey and potentially save yourself thousands of pounds on avoidable repair costs.

When Should You Book A Homebuyer Drain Survey?

A Homebuyer Drain Survey is best arranged after your offer has been accepted and before you exchange contracts. This gives you time to review the findings and raise any drainage concerns with the seller before the property becomes your responsibility.

A Drain Survey for Home Buyers can be particularly useful for older properties, homes with mature trees, properties with recurring drainage problems, or where drains run beneath extensions, patios or driveways. These issues may not be obvious during a viewing or standard property inspection.

If significant defects are found, the survey gives you useful information before you commit to the purchase. You may then be able to discuss repairs or the potential cost with the seller.

Common drainage issues a homebuyer survey can identify

Drainage problems are often hidden underground and may not show obvious signs during a property viewing. A CCTV inspection can identify issues such as:

  • Root ingress caused by tree roots entering pipe joints
  • Cracked or fractured pipes
  • Displaced or open joints
  • Blockages and debris build-up
  • Collapsed sections of pipework
  • Groundwater entering the drainage system
  • Gaps that could allow pests to enter

Identifying these problems before buying gives you a clearer picture of the drainage system and any repair work that may be required. These are issues BN Drainage’s CCTV surveys are designed to identify.

How does a homebuyer drain survey work?

Our engineers access the drainage system through an existing access point and guide a high-resolution waterproof CCTV camera through the pipework. The camera records the inside of the drains in real time, allowing defects to be located without excavation.

The inspection checks the accessible drainage system for structural damage, blockages, root ingress and other faults. The survey can also establish the location of defects and provide information about the drainage layout.

Following the inspection, you receive clear findings and recommendations. BN Drainage’s CCTV survey service also provides a written report, photographic evidence and recommendations showing what needs attention.

Arrange a Pre-Purchase Survey

If you are buying a property, arrange your survey before exchanging contracts so you have time to review the findings and consider any drainage issues before committing to the purchase. A CCTV inspection can give you a clearer picture of the condition of the property’s accessible drainage system and help reduce the risk of unexpected repair costs.

A drainage report for
mortgage peace of mind

Taking out a mortgage can be a daunting process, and you are likely to find yourself struggling to decide whether it is the right option to take. Homebuyers often don’t consider the condition of the drainage system at the property they are interested in when searching for a new home. However, nobody wants to find out there is an issue with the drains after they have already taken out a mortgage on the property. We can carry out a pre-purchase drain survey using CCTV to give you peace of mind. If we discover any problems with the drainage system that you didn’t know about, it could save you thousands of pounds on future repairs. This simple step can ensure you sign up to a mortgage with total peace of mind.

Once the CCTV drain survey has been completed, we provide clear reporting, video footage where required, and straightforward recommendations to help you make a more informed decision before purchasing the property.

Our efficient and professional pre-purchase drainage surveys help give homeowners and buyers greater peace of mind while keeping the process as smooth and stress-free as possible.

Frequently Asked Questions

What is a Homebuyer Drain Survey?

A Homebuyer Drain Survey is a CCTV inspection of the property’s accessible drainage system carried out before purchase. It can identify hidden problems such as cracked pipes, root ingress, blockages and collapsed sections that may not be visible during a property viewing.

Do I need a drain survey if I already have a homebuyer survey?

A standard homebuyer survey does not provide the same internal inspection of underground pipework as a specialist CCTV drain survey. A separate drainage survey can therefore give you more detailed information about the condition of the property’s drains.

When should I have a CCTV drain survey before buying property?

It is best to arrange the survey after your offer has been accepted and before exchanging contracts. This gives you time to review the findings and discuss any significant drainage problems with the seller.

Can a drain survey help me negotiate the property price?

Yes. If the survey identifies significant drainage defects, the findings can give you useful evidence when discussing repairs or potential costs with the seller before proceeding with the purchase.

What happens if the survey finds a drainage problem?

The survey can identify the location and nature of the problem and provide recommendations for what needs attention. You can then obtain appropriate repair advice and consider the findings before deciding whether to proceed with the purchase.

I would highly recommend BN Drainage. I called them out to fix a blocked drain, and they arrived within the hour. They quickly identified and fixed the problem, providing a fast, efficient and professional service. They also sent over a job sheet detailing the work they had carried out, which was really helpful and kept me fully informed throughout. Their prices were reasonable, and they were friendly and approachable from start to finish. Overall, a great experience with a reliable company that I wouldn’t hesitate to use again. Highly recommended!

We'd had a blocked manhole and a toilet that wouldn't clear properly for about two weeks, so I was glad to get someone out. A contractor from BN Drainage attended, explained clearly what the problem was, and got stuck in straight away. He was friendly, straightforward and didn't oversell anything. The engineer came out in the morning to finish the job. All sorted.

This is a bona fide feed back review about BN Drainage Ltd, written with integrity and honesty. We recently discovered the horror of broken gulley drains and leaking water into our basements (i.e. our neighbour and ourselves because the gulley grains were connected) and were introduced to this drain specialist by our local Whatsapp group. From the beginning to the end of the job they have been an excellent company. Courteous and respectful (for us an important part of the relationship with any company); They inspected the drains and we received a detailed breakdown & invoice of the work that had to be done. The cost was very reasonable and much cheaper than we anticipated. It was a big job because our neighbour's drain being connected to ours, meant that they had to do the 2 jobs together. They set a date for the repairs and came on time as planned. We were expecting a big messy job with mud everywhere, but they were respectful of our house and living space and curtailed the mess and mud and cleared away the old drains and debris and left the site clean ready for us to do our home cleaning-up. They removed the old drains, pipes & debris etc from our house altogether. We anticipated that our conservatory tiles would have to be broken during the work (and replicas hard to find since they had been down for many ears), but the engineers found they did not have to do this and preserved our tiles. We received an excellent professionally produced report about their findings (before and after the job) and details of the work they had carried out. They really do deserve a big 'thank you' for a job well done, for a very good cost and deserve a 5 star rating.
