How Our Drainage Company Can Help You  

From a 1-bed flat to a large block of flats or office spaces, every building requires a fully functional drainage system. Drains are vital for carrying water and waste away from the property, preventing either of these from building up. Should any problems occur with the drains or pipes, the consequences can range from a minor inconvenience to property damage and compromised living/ working conditions. Dealing with issues related to drains is not always straightforward. 

Fortunately, that’s where No1PHD can help. Our team is fully equipped and trained to tackle any issue concerning drains, from simple blockages to pipework that’s literally collapsed. We provide professional services intended to restore your drains and pipework to full working order in no time. And with multiple payment options available and no callout charges to worry about, fixing your drains won’t see you out of pocket.

Our team comprises professional drainage contractors with years of experience in fixing and servicing drains all over the UK. Our employees are fully vetted, qualified, and certified, and all are DBS-checked and carry IDs for your peace of mind. While we maintain an excellent track record, things can go wrong from time to time. When they do, you shouldn’t be the one left footing the bill. The good news is that our drainage contractors are covered by public liability insurance. 

This means that if anything goes wrong, we’ll ensure that the problem is dealt with at no extra cost to you. Blocked drains can occur for a whole host of reasons, and our team are trained to deal with them all. And should further work be required to restore your drains to full working order, know that we’re happy to oblige. 


The Drainage Services We Offer  

To ensure the health and performance of your drains, we provide a range of services, including: 

Drain Jetting  

Drains can become blocked for a whole host of reasons, from soap scum and hair to food debris, leaves, twigs, and other debris. Serious blockages require a lot more force to shift, and that’s where drain jetting comes in. Drain jetting is a process whereby water is pushed through the pipe at pressures high enough to dislodge the blockage. The force of the water is such (up to 4,000 psi) that it can blast away even the most hardened blockage, flushing it out of the pipe, so it can’t become stuck once more. 

The beauty of this method is that it also cleans the pipework, removing any fats, oils, and grease (FOG) as well as any other sludge deposits. It also shifts any debris that might be left stuck to the pipe, leaving a clear, free-flowing pipe. Because it cleans the pipework as well, any foul odours are dealt with. And because no chemicals are needed, drain jetting is eco-friendly. 

Drain Rodding  

Drain rodding is a specialist technique that’s typically employed for emergencies. It’s ideal for blockages located near a drain or manhole cover and is intended to remove congested blockages, using several different cutting tools to break down the blockage. This particular method is especially useful for tree root removal. While drain jetting can remove tree roots, it’s less effective. Drain rodding is often carried out before drain jetting as a way to soften up the congestion before blasting it away. 

Surface water drains carry rainwater away from a building’s gutters. These systems are susceptible to compacted leaves, soil, and other garden debris but are also prime candidates for drain rodding. Similarly, foul water drains which are designed for household waste from kitchens and bathrooms can also become blocked. These drains tend to be blocked by FOG as well as soap scum, hair, disposable paper products, etc. Once again, drain rodding is an excellent solution. 

Unblock Drains  

Drain unblocking is a vital service that we’re pleased to offer. Drains can become blocked for a whole host of reasons, and the location of the drain usually dictates what causes the blockage. For instance, external drains are far more likely to be blocked by compacted leaves, twigs, plant matter, and litter. Whereas internal drains are likely to be blocked by things such as: 

  • Hair 
  • Soap Scum 
  • Food Debris 
  • Fats, Oils, and Grease (FOG) 
  • Toilet Paper 
  • Wet Wipes and Sanitary Products 

The above is by no means an exhaustive list, and the causes differ depending on whether the blocked drain is situated in the kitchen, bathroom, utility rooms, etc. 

Whatever the case may be, you can trust that the team at No1PHD have what it takes to rectify blockages quickly, restoring drains to full functionality in no time. 

Leak Detection  

The majority of pipework is run behind walls or under floorboards, making leak detection a tricky business. Even a minor leak can cause mayhem, such as spoiling of paintwork or plaster, mould, structural rotting, unpleasant odours, etc. Occasionally, staining can betray the location of leaking pipes, but this is hardly a precise method. If you suspect leaks are present in your home, the best course of action is to call No1PHD . 

The average house contains at least four drains, all connected by a labyrinth of pipes that direct the water where it needs to go. Often, when a leak occurs, it’s tiny, so it’s tempting to put off having it fixed. Even a small leak can do a lot of damage. Besides rotting wood, staining, and mould, a leak can also cause electrical circuits to short out. This can even present a possible fire hazard or electrical hazard that could prove dangerous. 

At No1PHD, we possess specialist equipment that enables us to track down leaks using infrared technology, acoustic methods, and more. No matter how small the leak might be or where it’s located, we’ll have it tracked down and fixed as quickly as possible. 

Emergency 24hr Drainage Services

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.
