Portsmouth’s Complete Drainage Service Company

Our drainage services cover the whole range of problems encountered by householders, builders, business owners and managers of public premises in Portsmouth. From finding out the true cause of a problem, to using the latest high tech “no dig” techniques to fix it, we offer an end-to-end service. And for developers of Portsmouth new builds, we can map existing drains, and advise on the best configuration for a new drainage system.

Drainage Surveys

Our surveys are in demand from a range of residential and commercial customers. When there’s a problem, such as a spill, blockage, or “drains” odour, the cause may be obvious. We can set to work with our blockage busting equipment (see below). However, sometimes the cause is not obvious. We can use CCTV to find out what’s going in your drains, without digging them up.

Sometimes in the leafy parts of Portsmouth, we find that a tree root has worked its way into the drain, and broken the pipe, causing a leak or blockage. In the city centre, looking at a restaurant drainage system, we may find that fat and grease have accumulated, hardening inside the pipes and blocking them. On a new housing development, it may be that the pipes joining to the main sewage system need to be resized. Buyers of new houses may want to assure themselves that the drainage system is working correctly.

Whatever the reason, our expert drainage professionals at No1PHD will be able to map the drainage system, report on its status, diagnose any problem, and organise the remedy if needed.

Repairs, Unblocking and Cleaning

With high pressure water jets and advanced vacuum technology, we can unblock drains quickly, sucking up the dirty water and taking it away. We’re licensed waste disposers, so we can deal with the waste for you, and give you documentation if you need it.

Portsmouth restaurants and food premises sometimes have problems with fat and grease blocking drains. We can use high pressure jets to disperse hard fat, clean the drain, and install an efficient grease trap to prevent the problem recurring.

We also deal with soakaways and septic tanks which may be situated on the outskirts of Portsmouth. We are experts when it comes to working on these types of jobs and of course we can dispose of any waste that arises.

Absolutely blown away by the service we received. Took all the stress out of losing our heating and hot water. Highly recommended!

Couldn’t have asked for a faster resolution to our drainage conundrum. Nothing was too much for these guys who were brilliant throughout.

Repairing And Relining Drainage Pipes

It used to be necessary to dig up pipes in order to repair them. These days, we have a number of options available and will always try to avoid digging, because of the disruption it causes, and the fact that it’s more expensive. Instead, we can offer a range of high tech methods and cutting edge equipment that can deliver a more cost-effective solution. With our CCTV methods, we can identify a repair within a pipe, and rectify the problem remotely. One option is to reline the pipe, using a resin soaked lining that we can fit without digging up the site.

Installation Of New Drainage

Whether it’s a new build house or an extension, we can advise on what you need to do, survey the existing drainage and design an efficient new system. Houses and older industrial premises may have pitch fibre drainage. We can quickly assess whether any distorted or flattened pipes can be reshaped, or whether they will need to be replaced.

Whatever your drainage problem, or wherever you are in the Portsmouth area, contact us at No1Phd for a professional, cost-effective and prompt drainage service from a highly experienced company. Call us now on 01425 208031 for immediate service.

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.
