"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

It’s best to schedule regular gutter cleanings before there’s a major issue, but sometimes life gets in the way. Luckily, a few telltale signs will let you know when to clean your gutters ASAP:

  • You notice built-up debris in your gutters.

  • Your gutters overflow with water when it rains.

  • Water doesn’t readily flow from your downspouts.

  • Your gutters are damaged or visibly leaking.

  • You notice evidence of leaking along your roof, siding, yard, or pavement.

  • Your gutters have pulled away from your roofing or exterior walls.

  • You see water damage on your soffits or fascia.

  • You have weeds growing in your gutters.

  • You start to see ants or other insects around your gutters or in your home.

  • You suddenly have issues with leaks in your crawl space or basement.

Gutter guards and covers can minimize debris accumulation.

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.

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.

Yes, gutters can still get clogged even with gutter guards installed. While guards significantly reduce the amount of debris that enters your gutters, they are not 100% effective.

Small debris such as pine needles, seedlings, algae, small leaves, and pebbles can pass through the guard's screen or mesh and accumulate over time. Clogs can also form if the guards themselves are not cleaned and become overwhelmed with debris on top, preventing water from entering the gutter.

If this buildup is neglected, it can lead to clogs, water leaks, mold growth, and even plants sprouting from the gutters. The primary benefit of gutter guards is not the complete elimination of maintenance, but a dramatic reduction in how often you need to perform it, often from several times a year to just once a year or less.
