"Jonathan arrived on time and quickly got to work. He saw that some of the hangers hadn’t been attached to the house when the gutters were installed, so he attached them. He checked and cleaned all the downspouts as well. He even added a strainer to the top of a downspout that flows into a barrel so large debris won’t clog our sump pump. He took all the debris he removed with him, leaving no trace he had been here other than clean gutters. Jonathan was pleasant and professional and I’m very glad to have found True Gutters. I’ll definitely use him next time the gutters need cleaned!"

Gutter Cleaning FAQs, answered by experts

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.

Installing a leaf protection system that keeps leaves and pine needles out of your gutter downspout is the best way to prevent clogs. Additionally, you may want to remove any trees or branches that are hanging over your downspouts to prevent leaves and branches from making their way into your gutter system. Of course, routine downspout cleaning and inspection can also help you stay ahead of clogs that create water damage at your home.

Whether or not you can use a pressure washer to clean your gutter guards depends on the type of gutter guard you have and the strength of the pressure washer. Most gutter guards can handle a low-pressure setting but check first. If you’re unsure if your gutter guard is designed for pressure washing, check your manufacturer’s instructions, ask a pro, or use a garden hose to clean the gutter guard instead. As gutter guards age, they become less resistant to the strong forces of a power washer, so treat older gutter guards with more care.

Using less toilet paper is the easiest way to prevent future clogs. Also, avoid flushing sanitary products, thick paper towels, or hair down the toilet. If you’ve been using a brick in the tank to reduce the water used to flush the toilet, take it out immediately. Bricks will eventually fall apart and clog your toilet drain. Keeping your toilet lid closed also helps avoid future clogs.

Failing to clean your gutters can lead to serious and costly damage. When leaves and other debris cause blockages, water cannot drain properly and will overflow. This can lead to water pooling around your home’s foundation, causing basement flooding and structural damage. The overflow can also damage your roof, siding, and fascia boards, with the constant moisture promoting mold, mildew, and rot. The weight of wet debris can cause gutters to sag or break, while stagnant water creates a breeding ground for pests like mosquitoes and rodents. Additionally, runoff can damage landscaping or freeze on driveways and patios, causing cracks. To prevent these issues, it is recommended to clean your gutters at least once or twice a year.
