"I would 100% recommend Richard to anyone with the job he and his team did with power washing the exterior of our home. He was quick to provide us with an estimate, came to see the house within 2 days of submitting request. When I had questions he called and emailed and was very clear about what he was going to do. Our house VERY much needed a cleaning and now looks amazing after the wash! He also included a gutter cleaning service that was also much needed. He was a pleasure to work with and trust worthy. Thank you Richard!"

Gutter Cleaning FAQs, answered by experts

Frequently, when water flows over gutters, it indicates a potential clog, necessitating cleaning. For instance, if a twig becomes lodged in the downspout, it can lead to a traffic jam, causing more leaves and sticks to accumulate. Another potential issue is an incorrect pitch, as gutters should channel water toward the downspout. If you observe water overflowing the end cap or leaking through it, it suggests that your gutters are improperly tilted.

Regular inspections, occasional rinsing, and removing large debris ensure long-term functionality.

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.

Once you’ve installed your gutters, you'll need to maintain them. You should clean your gutters once or twice a year to keep them functioning correctly. But if climbing a ladder and scooping out handfuls of wet leaf gunk is just not your thing, you can hire a professional gutter cleaner near you to do the job. 

Buried downspouts can freeze during cold weather as cold water runs through them. If you’ve discovered your downspouts are frozen, you can carefully pour hot water down the top of the downspout to defrost them. If that doesn’t work, you may need to dig your downspout back up. Avoid trying to break the ice from the exterior using a hammer as this can cause cracks and damage to your downspout.

To avoid freezing the future, consider adding a heating cable to the exterior, which can adjust heat based on the surrounding temperature.
