Pricing a Plumbing Rough-In Job for New Homes: A Comprehensive Guide

May 15, 2023 | Blog, Job Bidding, Plumbing

As professionals in the construction industry, we continually face the challenge of accurately pricing our services. This task becomes even more complex when dealing with specialized tasks like plumbing rough-in jobs on new homes. The intricacies and variables involved can create a labyrinth of numbers, leaving many feeling lost. This article aims to provide a practical guide to pricing plumbing rough-in jobs in a way that ensures profitability, fairness, and customer satisfaction.

To begin with, it’s essential to understand what a rough-in job entails. This process involves installing the basic plumbing structure in a new home, including the water supply lines, drain-waste-vent pipes, and shower and tub units. The complexity and scale of the task depend on the size and design of the house. Make sure you have access to and understand the plans for the structure for which you will be doing the rough-in!

So let’s delve into the factors that determine the pricing of a plumbing rough-in job.

Labor Costs: Labor is typically the most significant part of the cost in a rough-in job. It includes the hours spent planning, preparing, and executing the job by the team. The cost of labor varies regionally and is influenced by the level of expertise required. An industry-standard method is to estimate the total number of hours the job will take and multiply it by your hourly rate.

  • Material Costs: Material cost is the second crucial factor. It includes the cost of pipes, fittings, valves, fixtures, and any other necessary supplies. It’s advisable to work with trusted suppliers to get quality materials at competitive prices. Over time, establishing strong relationships with suppliers can lead to discounts and better terms, positively impacting your pricing. Read this article for more information about dealing with rising materials costs.
  • Overhead Costs. These are the indirect costs of running your business, such as insurance, utilities, equipment, licensing fees, and office expenses. Overhead costs should be calculated annually and then divided by the number of jobs you expect to complete in a year to give a per-job overhead cost. Do not forget to factor overhead into your job bids! If you don’t, at the end of the year you will be wondering where all your profit went.
  • Markup. To ensure profitability, a markup on the total cost (labor, materials, and overheads) should be added. This percentage can vary based on the market, competition, and the specific job but typically ranges from 10% to 25%.
  • Contingency. Always add a contingency of around 10% – 15% to account for unforeseen issues like delays, extra materials, or additional labor costs. Read more about contingencies here.

  • Location Factors. The location of the project also affects the cost. Projects in urban areas or those with challenging access may have higher costs due to parking, transportation, or extended travel time.
  • Design complexity. The complexity of the home design is also a significant factor. For example, a larger house with multiple bathrooms and complex features like a whirlpool tub will require more time, materials, and expertise, thereby increasing the cost. Therefore, always consider the house design complexity in your pricing structure.

Tracking your job costs with a tool like ProfitDig makes it much easier to be accurate in your bidding with regard to things like profit margins and overhead. You might think you are making money – but are you really? If there is no profit left when the job is done, then you have done something wrong. You won’t know where you went wrong if you don’t track your costs.

It’s also crucial to keep up to date with technological changes in the industry. For instance, the advent of PEX (cross-linked polyethylene) plumbing systems has revolutionized the plumbing industry, offering a quicker installation time and lower material costs compared to traditional copper systems. Incorporating such advancements into your services could lead to more competitive pricing and higher customer satisfaction.

Negotiating with suppliers for better prices or terms can also have a significant impact on your costs. Regularly review your supplier relationships and seek out new opportunities to improve your terms or find more cost-effective materials without compromising on quality.

Furthermore, consider your competition. Understanding the market rate for similar services can help ensure your prices are competitive. While you shouldn’t undercut yourself, it’s essential to be aware of what others are charging to avoid overpricing or underpricing your services.

Lastly, don’t forget the value of your expertise. Experienced plumbers can often complete a job faster and with fewer mistakes than less experienced ones. This expertise can justify a higher price, so don’t undersell your skills and experience.

Based on the above, the formula to calculate the total price on a plumbing rough-in job would be:

Total Price = [(Labor Hours x Hourly Rate) + Material Costs + Overhead Costs] x (1 + Markup/100) x (1 + Contingency/100)

Using the previous example, if your rate is $85/hour, material cost is $2,000, per-job overhead cost is $500, markup is 20%, and contingency is 10%, the total price would be:

Total Price = [(50 x $85) + $2,000 + $500] x 1.2 x 1.1 = $8,580

It’s crucial to communicate the pricing and all factors included to your client clearly. Transparency fosters trust and helps avoid misunderstandings later on.

In summary, pricing a plumbing rough-in job is a delicate balancing act. It involves understanding your costs, gauging the complexity of the job, keeping abreast of industry changes, and considering the market and your competition. With a thorough, systematic approach, you can ensure your pricing is fair, competitive, and profitable, leading to a sustainable and successful business.
