Common Types of Plumbing Services

Longmont's professional plumbers typically offer the following services.

Leak Repair

Have leaks repaired as soon as possible, because even a trickling faucet can drive up your water bill. Professional plumbers are trained to repair leaks and identify their cause to prevent future leaks.

Drain Cleaning

Debris buildup that blocks drainage can damage your pipes and result in flooding. When ignored, blockages can even lead to structural damage. Professional plumbers are trained to identify the cause of clogs and remove them without damaging your plumbing system.

Bathroom Installation

Plumbers can install or replace showers, tubs, sinks, and toilets. Vet your plumber thoroughly, especially when hiring for a more expensive project. You want a licensed contractor with good customer reviews and sufficient industry experience.

Gas Inspection and Installation

Some plumbers have the skills to repair your stove, hot water heater, or oven. Some plumbers are trained to work on gas leaks and repair or install gas pipes and appliances. This work can be dangerous, so ensure you're hiring a highly credentialed plumber.

Inspection and Maintenance

Your household plumbing experiences lots of wear and tear, particularly if there are several people under your roof. Having a plumber regularly inspect and maintain your plumbing system can lower your chances of inconvenient and expensive repairs in the future. We recommend a yearly inspection.

Emergency Plumbing Services

The worst plumbing issues are those that happen in the middle of the night. Whether you're dealing with a burst pipe or some other emergency, you want to have contact information for a plumber that offers emergency services. This way, you won't have to wait until morning to fix an urgent problem.

How to Choose a Plumbing Service in Longmont

It's important to find a plumber that offers quality services at a reasonable price. Below are some important considerations when selecting a plumbing company in Longmont.

Reputation and Reviews

Always look for customer reviews before signing a contract with a plumber—you want to be sure you're hiring an expert who can provide quality services. Also ask to see a plumber's license from the Colorado Department of Regulatory Agencies and proof of business insurance before signing a contract. You want to know that anyone working on your home is properly credentialed.

Many prefer to hire a professional from a union. Services will likely cost more, but you'll know your plumber has been vetted thoroughly.

Services Offered

You want to ensure any plumber you hire is qualified to provide the services you need. Check a company's website to verify that it offers the necessary services, and ask your contractor about their past plumbing experience. You can even ask for photos of previous jobs.


Request a price estimate from more than one plumber to compare rates. Then, balance cost with qualifications and reputation to come to a decision. Prioritize quality work over cost as much as your budget allows.
