Pipe relining is a relatively new method that is less intrusive compared to replacing the entire plumbing system. It is also cost-effective considering that the plumber will only touch the damaged sections of the drain or sewer pipe. Compare that to the traditional way of excavating and pulling out the old pipe, and you can imagine the improvement in the technique used.
But the most important question is how much does pipe relining cost? It is not easy to make an approximate estimate because of the multiple factors involved in determining the cost.
First, it is important to know the factors that will affect the total bill of the work:
- The diameter of the pipe – The rule of thumb employed by plumbers is simple: the larger it is, the more expensive it is going to be. It is because they would need to use more resin or liner to make a create artery to reline the old pipe. The length of the relined pipes will also affect the cost because they compute the estimate per-square-metre. This type of computation is also employed in the traditional method of pipe laying and replacement.
- The complexity of the task – Of course, the more complicated the job at hand, the more time the plumbers will spend on the project. For example, a piping system with lots of junctions, bends, and cuts would be more time-consuming compared to a section with a straight line. The trenchless pipe relining method, however, will still simplify an otherwise complicated task because the plumbers can pinpoint the damaged pipes more accurately.
- Access to the pipes – Another thing to consider is the access to the pipes. If the plumbers have to dig a huge trench to get to the pipes, then the labour hours will be added to your bill. Another example would be if the pipe in question is located on a multiple-storey building with no elevator access, the plumbers would be carrying heavy tools and equipment up and down the stairs.
- Using special equipment – If the plumbers use specialized tools like robotic cutters or CCTV cameras, then it may also determine the total cost of the job. The method used–whether pull-in-place relining, cured-in-place relining, pipe coating, or pipe bursting–is also a typical way to determine the cost.
- Risks to personnel – The service provider will also consider the risks in the environment that could endanger the lives of the technicians. For example, using additional equipment like cables, safety harnesses, and the like, would impact on the cost.
- Local fees – You may also pay local fees if the plumbers need to block the road to fix your pipes. For example, in Sydney, you need to apply for a permit to do so, and the authority costs $1,750. You also need to pay an additional $2,000 per day per block that you are going to close the road. Lastly, you may need to pay the traffic personnel about $850 per day. Those charges are on top of the plumber fees of relining your pipe.
To get a more accurate estimate of the pipe relining cost, you must call the service provider. It does not cost anything to secure a quote from the plumber. The advantage is that you can rationalise your budget because you have a good idea of the expense.
