Reliable Repairs That Keep Systems Running

DNI Heating and Air provides full-service plumbing repair for homes and businesses in Boulder, Colorado.

When a pipe bursts during a cold Boulder morning or your toilet begins leaking into the flooring, you need a repair that stops the problem and restores normal function quickly. Plumbing failures interrupt daily routines and can lead to water damage if left unaddressed, which is why prompt, accurate repair work matters more than convenient timing.


DNI Heating and Air handles repairs across the full plumbing system, including sewers, toilets, plumbing fixtures, drains, pipes, main water lines, and water heaters. Whether you are dealing with a slow drain that backs up during heavy use or a water heater that no longer holds temperature, the repair process starts with identifying the source of the failure and determining whether a component can be repaired or needs replacement. Both residential and commercial properties in Boulder are serviced, and the work is performed to current code standards.


If you are dealing with a plumbing issue in Boulder that is affecting your daily operations or comfort, reach out to discuss what is happening and schedule a repair visit.

Repairs Address Both Visible Damage and Hidden Failures

Plumbing repair begins with assessing the visible symptoms and tracing them back to the underlying cause. In Boulder, this might involve inspecting a fixture that has stopped working, checking pipe connections for leaks, or clearing a drain that has slowed or stopped flowing. Depending on the issue, repairs may involve replacing a valve, clearing a blockage, resealing a joint, or swapping out a worn component that no longer performs as it should.


Once the repair is complete, you will notice that water flows at the correct pressure again, drains empty without hesitation, and fixtures operate without dripping or running continuously. Toilets flush cleanly, water heaters deliver consistent temperature, and there is no pooling water or damp spots where connections were previously failing.



Some repairs require accessing walls or floors to reach pipes that are not immediately visible, while others involve replacing external fixtures or clearing lines from an access point. The scope of the repair depends on where the failure occurred and how the system was originally installed. Work is completed according to local building codes, and any replaced parts are selected to match the existing system or offer improved durability where appropriate.

We Understand You May Have Questions About What the Repair Involves

Homeowners and business owners often want to know what kind of work will be needed, how long the repair will take, and whether the issue is likely to return. These are all practical concerns, and the answers depend on what is actually failing in your system.

What types of plumbing problems do you repair?

We repair issues with sewers, toilets, plumbing fixtures, drains, pipes, main water lines, and water heaters. If something in your plumbing system has stopped working or is leaking, we assess the cause and perform the necessary repair.

How do you determine what caused the plumbing failure?

We inspect the affected area, test water flow and pressure, and check connections and components for signs of wear, corrosion, or blockage. In some cases, we may use a camera inspection to see inside pipes that are not easily accessible.

How long does a typical plumbing repair take?

Most repairs are completed within a few hours, though more complex issues such as main line work or sewer repairs may take longer depending on access and the extent of the damage.

Do you handle plumbing repairs for commercial properties in Boulder?

Yes, we provide plumbing repair services for both residential and commercial properties throughout Boulder. Commercial systems often have higher demand and more complex layouts, which we account for during the repair process.

What should I do if I notice a leak or plumbing issue?

Turn off the water supply to the affected fixture or area if possible, and contact us to schedule a repair. The sooner the issue is addressed, the less likely it is to cause secondary damage to floors, walls, or surrounding materials.

Plumbing repairs are most effective when they are performed before a small issue becomes a larger failure that affects multiple areas of your property. If you are noticing changes in water pressure, hearing unusual sounds from your pipes, or seeing signs of moisture where there should not be any, contact DNI Heating and Air to schedule an inspection and repair in Boulder.
