Get matched with top gutter cleaning pros in La Jolla, CA

The cost to install a downspout extension or reroute a downspout generally falls between $30 and $200. The final price depends on factors like whether you DIY the project or hire a gutter professional, the complexity of your gutter system, and the length of the new extension. A simple, above-ground DIY installation can cost as little as $30 for materials. In contrast, a more complex project involving professional installation and digging trenches for underground piping could cost over $1,000. This is still a significant saving compared to replacing your entire gutter system, which costs around $1,900 on average.

The kind of gutter guards you have will affect how often you need to clean them. The more basic type of gutter screen requires cleaning once or twice a year. With a micromesh screen, you may be able to extend the time between cleanings to every two years or so.

However, if you have trees near your roof, you’ll need to clean your gutters more frequently, especially if you have chicken-wire or colander-type gutter guards. If you have pine trees near your roof, you may even need to clean your gutters quarterly, as tiny pine needles can get through any type of gutter guard.

Any small amount of standing water can be damaging to your gutters. It’s recommended that a ¼ inch puddle or more should be addressed. Failure to keep water from pooling in your gutters can result in clogs, algae growth, and pests that damage your gutters over time. 

Yes, you can use a pressure washer to effectively clean debris, dirt, and grime from your gutters, but it must be done with caution to avoid damage. Always use a low-pressure setting, with a recommended range between 1,200 and 1,800 PSI. Excessive pressure can bend or dent aluminum gutters, damage seams, peel paint, or even knock shingles off your roof, potentially leading to leaks and moisture issues. For a safer alternative, consider soft washing or cleaning them by hand. When using a pressure washer, it is safer to use gutter elbow extensions from the ground rather than climbing a ladder, as the force can cause instability. Due to the risks, you may want to hire a licensed and insured contractor for the job.
