Comparative Summary

Few gutter companies earn the prestigious Diamond Certified award, which means they’ve been independently rated Highest in Quality. Even fewer can also claim to be one of the first companies in Northern California to install seamless gutter systems, but that’s exactly the case for Superior Seamless Gutter. “We’ve spent the last 25 years fine tuning our own unique system, which has allowed us to develop a very loyal clientele base,” says owner Greg Van Cleave. “Our goal is to do every job right the first time, and we’re able to use our industry experience and product knowledge to achieve that.”

Superior Seamless Gutter has been installing copper and pre-painted galvanized steel gutters in a variety of sizes and styles for residential and commercial clients in Sonoma, Marin and Napa Counties since 1986. The family-owned and operated company works on all types of projects, including simple gutter replacements, new construction jobs, hilltop mansions, custom homes and wineries.

Unlike less experienced gutter companies that strive to maximize their workload volume but become unresponsive to customers’ needs in the process, Superior Seamless Gutter prides itself on its ability to clearly communicate with its clients and guide them through every step of their projects. “Some gutter companies can be hard to reach on the phone, but we make a point to always be easily accessible so we can answer questions, give prices and dispatch technicians right away,” explains Mr. Van Cleave. “If we need to quickly contact our crews when they’re on a jobsite, we can do that, too.”

Another distinguishing attribute of Superior Seamless Gutter is its ability to offer lifetime warranties on both its work and products, which Mr. Van Cleave says is indicative of his company’s staying power. “We’ve had customers from 20 years ago call about small leaks, and they were so pleased to find out we were still in business. A lot of gutter companies come and go, but we’ve been around for more than two decades and will be around for many more, so our customers know their warranties will be good whenever they need them.”

Industry Info

When it comes to choosing gutters for a house, the two most popular types of material are aluminum and galvanized steel. While these materials tend to be comparable in price, there are pros and cons regarding the functionality of each, so it’s important to understand the differences when deciding which type to install on your home. Consider the following information:
Aluminum
As a gutter material, aluminum’s greatest strength is its resistance to corrosion. Its elemental composition makes it impervious to rust, so it doesn’t need any special treatments or coatings and can be ideal for areas that get a lot of rain and moisture. Aluminum’s biggest weakness is its flimsiness, so aluminum gutters are prone to deformation caused by ladders, warping caused by extreme heat and bowing caused by an excess of water.
Steel
Steel’s greatest advantage is its strength—unlike aluminum, it won’t bend, scratch, or become deformed by ladders or weather. There are a few different types of steel that are currently used for gutter material: regular, stainless and galvanized. Some older homes still have regular steel gutters, but they’re no longer used due to their high susceptibility to rust. Stainless steel is the only fully rust-proof variety, but this attribute also makes it a significantly more expensive option. Galvanized steel is the most popular of the three because of its cost-effectiveness: it’s less expensive than stainless steel, while its vulnerability to rust is greatly reduced by the process of galvanization (a chemical treatment that coats the steel with zinc). Though still not as rust-resistant as aluminum, additional treatments and/or coatings to galvanized steel gutters can further improve their imperviousness to corrosive elements.
There are other options for gutter materials (vinyl, wood, copper), but the enduring popularity of aluminum and galvanized steel is a testament to each material’s affordability and functionality. The best option for your particular situation depends on your living conditions and a variety of other factors, so talk to your local gutter installer or hardware supplier before making a decision.

Frequently Asked Questions

Q: Why is it important to have gutters on my house?

A: There are many reasons, but the most important is to control the water that lands on your roof. Excess standing water can have a negative effect on the integrity of your home’s foundation, and gutters are the best way to divert that water away from your house.

Q: Will gutters detract from the look of my home?

A: No. Gutters are actually painted to match the trim color of the house, so they’re decorative as well as functional.

Q: What gutter style is best suited for my house?

A: There are several different styles available. We usually direct potential customers to our website, where they can actually see how our products look when installed on different styles of homes.

Q: Are your employees well-trained and trustworthy?

A: Absolutely. A lot of our employees have been working here for 10 to 15 years, and each has been personally trained by either our owner, Greg Van Cleave, or his son, Corey. We train our employees according to our own system, which ensures all work is performed the same way every time.

Q: How are you able to offer a lifetime warranty?

A: We have full confidence in our installations and the products and sealants we use. We’ve spent the last 25 years fine tuning our services, so it’s easy for us to stand behind everything we do.

Q: What types of half-round gutters do you offer?

A: The half-round gutters we offer are available in pre-painted aluminum, unpainted galvalume and copper.

They did a professional job. I let them know they left some of the old gutter guards on top of my roof and they immediately came over and removed them. They were right there, the gentleman didn't realize it had happened. They were very prompt in taking care of that problem.
