New gutter installation protects your home's foundation, siding, and landscaping from roof runoff damage. We install seamless aluminum gutters custom-fabricated on-site to the exact length of each eave run, eliminating leaky seams. Standard 5-inch K-style gutters handle most NorCal residential roofs, while 6-inch gutters are recommended for steep-pitch or large roofs. Downspouts route water at least 4 feet from the foundation. We offer a range of colors to match your home's exterior.

Sacramento's wet season (November-March) delivers heavy rainfall that overwhelms undersized or clogged gutters. Properly sized seamless gutters prevent foundation erosion and basement flooding during atmospheric river events.

Redwood City is located in San Mateo County (Peninsula). Climate best by government test — revitalized downtown with older bungalows and new condos. The local utility provider is PG&E.

Gutter Installation in Redwood City — FAQ

How much do new gutters cost in Sacramento?+

Seamless aluminum gutters installed by a professional run $6-$12 per linear foot in NorCal, or $900-$1,800 for a typical home with 150 feet of gutter. Copper gutters cost $25-$40 per foot.

What size gutters do I need?+

Standard 5-inch K-style gutters handle most Sacramento-area homes. If your roof has a steep pitch (8:12 or greater) or large surface area, 6-inch gutters are recommended to handle higher water volume during heavy rain.

How long do aluminum gutters last?+

Seamless aluminum gutters last 20-30 years with basic maintenance. NorCal's mild climate (no freeze-thaw cycles) is easy on gutters. Regular cleaning and occasional resealing at end caps keeps them performing well.

Should I add gutter guards with new gutters?+

If you have trees near your roofline (especially oaks or pines common in NorCal), gutter guards significantly reduce maintenance. We recommend micro-mesh guards for the best leaf and needle filtration.
