Drainage Surveys

A drainage survey is the sure fire way to get robust information about where the drains are, how they connect to other pipes, and what condition they are in. From housebuilders to homeowners, No1PHD’s expert drainage surveys can prevent damage to existing drains, identify any problems, and help you to identify maintenance priorities.

Our expert, detailed survey will provide accurate information on where the problem actually is. Without it, you could waste money on drainage repairs, while the actual source of the problem is in a different part of the drainage system.

We also provide a key planning resource for homeowners who are starting new building projects. Property owners who are adding extensions or garden rooms, don’t want to accidentally rupture a drainage pipe on their property, and end up flooding their garden with sewage. The No1PHD surveyor will map the existing drainage system while you are at the planning stage.

Drainage Surveys For Buyers Of New Builds

In new build properties, the drainage systems can’t be tested until near the end of the build, when bathrooms and kitchens are being installed. At that point, it’s difficult to identify if there are any problems, and general surveyors don’t carry out full drain surveys. No1PHD bridges this information gap by supplying Guildford professional drainage surveys for buyers, as a check that the drains have been correctly installed. If the connection of the new drains to the existing sewage system hasn’t been done correctly, damage can occur, in the form of back-up and flooding. The last thing you want in a new house.

If our survey report shows that all is well, you can complete your house purchase, knowing that the drainage won’t be a problem. If there is a problem, we can tell you both what needs to be done, and how much it will cost to remedy. This gives you a firm basis for negotiation with the builder.

At No1 PHD, our professional drainage reputation ensures that any problems we highlight will be taken seriously by the builder. For example, we have the knowledge and expertise to be very specific about what the actual problem is. Common issues such as blocked drains residents seem to acquire quite often will be picked up on our surveys. We often identify instances of the wrong pipe sizes being used, incorrect connections, and so on. We also find cases where the fact that the new house has been built on top of an existing drain, has damaged the old drain, resulting in a number of problems.

Drainage Surveys For Builders And Contractors

Responsible contractors try to ensure they don’t hit these kinds of problems, by using NO1PHD’s expert drainage surveyors, to identify possible problems well before the new drainage system is designed. Our data allows builders to remedy or work round problems, at the planning stage, when access is easy. In this way, we can help contractors to avoid lengthy disputes with buyers, or damage to the newly built property.

How No1PHD Carries Out A Drainage Survey

The development of Closed Circuit Television (CCTV) has made the job of surveying drains much easier than it used to be. Using our cutting edge camera technology, we insert the camera into the drain, and the pictures are beamed back remotely, beaming back the pictures to one of our expert technicians. Our CCTV systems are extremely flexible. They can be used with very small pipes – just 50mm diameter. At the other end of the spectrum, large bore pipes with a 1 metre diameter or bigger, can also be surveyed. What’s more, we can investigate long pipe runs from a single entry location – this makes our surveys highly cost-effective in country or coastal areas, or where properties have large grounds.


No1PHD Can Deal With The Entire Job

Sometimes it’s necessary to clear the pipe before the camera can record video. It may be clogged with fats and oils, or have a blockage, or be full of sewage. In this case, you need a multi-service company, like NO1PHD. We can promptly provide a JetVac tanker, also used for clearing septic tanks or providing sewer services. We can use water jets to clean the pipe, and also vacuum out debris and fat, so that the CCTV picture is clear.

Not all drainage installations are underground, and our high-tech CCTV equipment can also inspect downpipes, ducts, soil stacks and other above ground drainage systems. If any pipes have bends in them, a push rod system allows our engineer to move the camera round the curve in the pipe, to get the full picture.

Why Drainage Surveys Save Money

Pipe or drain damage, resulting in sewage backup or floods, can be extremely expensive, and can even lead to third party liabilities, if public land, waterways, or neighbours’ properties are affected. So the financial risk is very high, whereas our surveys are extremely cost-effective. This is why many owners and organisations use the drainage survey findings reported by No1PHD, to organise the preventative maintenance programme on their pipes and drains. We can diagnose problems early on, and help our clients deal with them while they are minor rather than major.

Drainage surveys are vital tools in maintaining drainage systems, and fixing problems.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
