NOAA forecasts a very strong El Niño for late 2026, but exact Bay Area rainfall remains uncertain. Our advice is simple: prepare before storms expose an existing drainage problem. View the NOAA/CPC outlook.
Calm preparation. Professional service.
Make sure water has a clear path away from your home
Clogged gutters can overflow against fascia, siding, walkways and foundations. Roof moss, leaves and loose debris can wash into the gutter system during heavy rain, while blocked downspouts can turn a manageable storm into a preventable maintenance problem.

Gutter Guard Installation
Reduce future debris buildup with guards selected for your roof and surrounding trees.
□
Roof Debris Removal
Clear loose organic material that can wash into clean gutters during the first storms.
↘️
Downspout Flow Check
Confirm visible downspout flow and identify obvious blockages before heavy rain arrives.

□
Drainage-Sensitive Cleaning
Clean slippery or stained exterior surfaces while accounting for nearby drainage points.
Why book before the rush?
Heavy rain exposes weak points quickly
A dry-day inspection and cleaning gives you time to address clogged gutters, roof debris, loose downspout connections and recurring overflow areas before appointment calendars tighten around the first major storm.
We provide practical recommendations based on the condition of your home. If a service is not needed, we will say so.

Winter rain-readiness FAQs
Questions homeowners ask before storm season
Does El Niño guarantee heavy rain in San Mateo County?
No. NOAA forecasts a very strong El Niño, but seasonal conditions do not guarantee a specific amount of rain in one city. The practical reason to prepare is that any major storm can expose existing gutter and drainage problems.
When should gutters be cleaned before winter?
Before the first sustained period of heavy rain—and earlier if your roof is surrounded by trees or you already see gutter overflow, staining or visible debris.
Do gutter guards eliminate gutter maintenance?
No system is completely maintenance-free. Properly selected guards can reduce larger debris buildup, but periodic inspection and cleaning may still be needed.
Can roof debris clog newly cleaned gutters?
Yes. Leaves, needles, moss and loose roof debris can wash into the gutter system during rain. That is why roof and gutter conditions should be considered together.
Do you use high pressure on roofs?
We use surface-appropriate, low-pressure soft-washing and roof-care methods. We do not treat every exterior surface with the same pressure.
