How Do I Unclog a Gutter Downspout? Complete Guide

April 29, 2025 | by empiregutters

Homeowners install gutters to protect the foundation and exterior of the house from potential water damage. However, this purpose may fail if you do not maintain the gutter system. Regular cleaning of the gutters and downspouts is extremely essential to keep the water flowing smoothly. In case of a clogged downspout, the water can flow out of the gutter and cause damage to the house’s exterior. While many homeowners prefer to clean the system on their own, it is advisable to contact the experts for downspout cleanout in Vancouver

While experts are always handy for unclogging a downspout, it is always better to know the method. Here, we will discuss the unclogging method along with many other details about the downspout cleanout in Vancouver. 

Why is Downspout Unclogging Crucial?

First, let us understand why the unclogging of gutters and downspouts is so important. Here are some of the potential reasons why you must unclog the downspout regularly. 

  • Water Damage:

When the downspout is clogged, the water starts overflowing from the gutter, ultimately causing damage to the foundation, roof, and even the walls of the house.

  • Efficient Drainage System:

When water floods the foundation, it causes soil erosion, mold, and similar damage.  Now, when the water flows through the downspout, the water falls away from the foundation. So, whenever the downspout gets clogged, it will again lead to flooding at the foundation. 

  • Lower Pest Invasion:

When any part of the gutter is clogged, it becomes a breeding ground for various pests and insects. They not only damage your house but also cause various health issues for the residents. 

  • Avoids Accidents:

Clogged downspouts will exert pressure on the soffit and the fascia board of the gutter. If you ignore the situation for a long time, the gutter may collapse, causing a massive accident. 

How to Check a Clogged Downspout?

To check for clogging in the downspout gutter, you must first clear the gutter. Get on the mission of cleaning the gutter on a sunny day. You will need this set of equipment for the check:

  • A ladder
  • Safety glasses
  • A Scooper 
  • Gloves
  • Garden hose

Use the ladder to reach the height of the gutter, and then scoop out dry leaves and other debris from the surface of the gutter downspout extension and other parts of the gutter. Ensure that you wear your gloves and safety glasses during the process. Once you are sure that you have removed all the debris, use the garden hose to wash the gutter with high water pressure. The water force will drain out all the remaining debris from the downspout. 

Now, check whether all the water is draining through the downspout or if it is flooding the gutter. If the water is flooding the gutter or is draining extremely slowly, then you must understand that the downspout is clogged. Next, you must get into the procedure of unclogging the downspout. You can either try to clear the clog yourself or call upon an expert at downspout cleanout in Vancouver to get the task done. 

Tools to Unclog the Downspout

You can use different tools to unclog the gutter downspout drainage system, depending on availability. Here is a list of tools you can use while unclogging the gutter downspout on your mission. 

  • Unclogging Tool:

One of the finest tools for unclogging a downspout is the plumbing snake. It is a metal cable with an uncoiled spring at the end. You can insert the plumbing snake from either the top or the bottom of the downspout; the primary goal is to reach the clogged portion. You may have to use this tool several times to clear out the clog. 

  • Leaf Blower:

A leaf blower is a pipe with a nozzle that propels air at high pressure. While it helps remove debris, you can also use it to clear a light clog from the downspout. 

  • Vacuum Cleaner:

The vacuum cleaner is another great tool that helps in unclogging the downspout. The cleaner utilizes the suction feature to clear clogs. Put the nozzle slightly in the downspout to suction the clog with more power. 

  • Power Washer:

While most people use a regular hose to remove debris, a power washer is more powerful for clearing clogs. It removes the clog with hot water under extreme pressure. If you want quick results, this can be an amazing tool for your clog removal procedure. 

If you do not have the required tools, you can always call upon the professionals at Downspout Cleanout in Vancouver for the purpose.

Now that you have collected the necessary tools, here is a simple guide on how you can clear the downspout clog. 

  • Exposing the Opening:

The first and foremost step is to expose the opening well so that you can reach out to the debris and clog. The downspout opening may be secured with screws at the gutter downspout connector, so you must carefully remove them for cleaning. Start by cleaning the bottom opening, as it will be much easier for you to do so. 

  • Remove the Debris:

Now, use a scoop to remove the debris from the downspout. You can even use a vacuum cleaner to clear up all the debris stuck up in the downspout. 

  • Check the Clog:

  • Use a Tool to Clear the Debris:

  • Try from the Top:

If you see that the clog is still there even after using powerful tools, you must try clearing the clog from the top of the downspout. Use a ladder and ask for help so that you can climb and try to clear the clog from the top opening of the downspout. In the event of an extremely rigid clog, the professionals at Downspout Cleanout in Vancouver arrive equipped with special tools to clear the clog.  

  • Rinse the Downspout:

Once the clog is cleared, do not leave the debris anywhere in the downspout. Even the dust particles left in the downspout can clog it again, causing the problem to recur. So, you must rinse out the downspout carefully using a garden hose. 

  • Check Water Flow: 

Once you believe the clog is clear, follow the steps to check whether the water is flowing smoothly now. Put water in the gutter and notice whether the water is flowing properly through the downspout or not. Hopefully, when you have used the necessary tools to clear the clog, the downspout will be clog-free.

How Often Should I Clean Gutter Downspouts?

  • The Surroundings:

The surroundings of your house play a significant role in determining how often you should clean the gutter system. If there are many trees surrounding your house or you have a garden, the leaves and twigs from the trees can fall onto the roof and clog the downspout. In this case, you should check the gutter at least twice a year.

The weather conditions of a place also matter a lot when you are unsure how often you should clean the gutters. If you live in an area with regular rainfall and snow, it’s essential to clean your gutters every 3 months. On the other hand, if the seasons are predictable, you can decide a schedule throughout the year. For example, you can get a cleaning done before the rain starts or when autumn is over.
