Writing a Plumbing Proposal Letter

 Use this sample plumbing proposal letter as a template for your formal proposal letter.

A plumbing proposal letter is intended to offer plumbing services for a particular job. If the customer is smart, they will look for bids from several plumbers for their project and select the one that gives the best value for money.

The best way for a plumber to win the job is to:
• Thoroughly understand the work that is required
• Give a cost estimate and, ideally, promise to stick to it without added costs at the end of the project
• Give an accurate-as-possible estimate on the amount of time the job will take
• Give license details that show they can do city-approved work

The proposal letter is the plumbing contractor’s chance to clearly express why their company is the right one for the job. They can give information about their experience in successfully completing similar jobs as well as a list of employees and their qualifications such as licenses and certificates.​​

It is not recommended for plumbing businesses to overstate their qualifications in order to present themselves as more competent than they are. The truth will come out in the end. The cost proposal is generally given on a separate page and may be itemized with the cost of materials, labor and any subcontractors the plumbing contractor is planning to use.

​Project experience is the main selling point for the plumbing contractor. This is the reason a person or business will be attracted to one contractor over another. For example, if the contractor is making a proposal to a municipal or other government agency for plumbing services, they should not only include their experience with the specific plumbing services but also their experience working with government agencies.
​
Residential vs. Commercial Projects

The letter should differentiate between residential and commercial projects. If they are bidding for a commercial project such as all the plumbing in a housing development, they need to show that they have experience in such large projects and can handle the job. Along with experience, they need to show that they have the qualified personnel to handle a large project. This is not the place to state that they can fix a blocked kitchen sink.
​
On the other hand, if the project is for a private individual, the letter doesn’t need to go into all the huge commercial projects they have done. The individual will want to know if they can fix their leaking pipes and will guarantee their work. The proposal letter should focus on the required job.

Double Check Each Detail

Before submitting a proposal letter, the plumbing construction company should double check each detail of the proposal including the cost of all pipes, fittings and faucets as well as labor. The price for the services should be sound financial business for the company. People will pay for high-quality work, so it is not in the company’s best interest to give a very low estimate to get a job that loses money.

Today, customer service is paramount. Any plumbing company can have good and bad testimonials posted on the Internet from customers. For this reason, and for the integrity of the company, they should keep any promises they make in a proposal and not change prices or timing at the end. This is the best way to lose customers and get bad testimonials.

Here is a sample plumbing proposal letter. It is for a general plumbing contract for an apartment building, but can be modified for individual residential use. It should be written in formal business-style and be sent by certified mail, so the sender is sure that the proposal was received.

Note: While much of the same information that is in the proposal letter will also be in the business plan, the purpose of the letter is to give the possible client a quick view of the important facts. The aim is to make the possible client feel interested in reading the business plan.
