Video: Benefits of Sealing Your Attic Floor

SACRAMENTO — Sarah Rutan: When it comes to insulating your attic, there’s a key component you don’t want to overlook. Today we’re in Sacramento with Diamond Certified Expert Contributor Greg Sutliff of Alcal Specialty Contracting to learn more.

Diamond Certified Expert Contributor, Greg Sutliff: Most homeowners know that to improve the energy efficiency of their home, they need to increase the insulation in their attic. What most don’t know is that air sitting on that attic floor is also a very key component to improving the energy efficiency of the home. A side benefit to insulating that attic floor is the improvement of indoor air quality that will happen once that attic floor air sealing is completed. Read more

PLEASANTON — Host, Sarah Rutan: Due to the important role attic insulation plays in home energy efficiency, it’s important to make sure you have an adequate amount. Today we’re in Pleasanton with Diamond Certified Expert Contributor Kevin Comerford of Service Champions to learn more.

Diamond Certified Expert Contributor, Kevin Comerford: Another tip that homeowners can do in order to make sure their heating and air-conditioning system is operating properly is ensure that they have the right levels of insulation in their home.

Specialty Spotlight: Cabinet Refacing

Posted on September 18, 2018 by Suzanne Carroll

A complete kitchen renovation is expensive. The average cost is about $23,000, with high-end transformations costing upward of $50,000. The priciest part of these renovations is the cabinetry, as it requires significant planning, resources and labor to install. However, homeowners looking to save money and time may find that cabinet refacing is an easier and less expensive option for achieving the results they want.


What is cabinet refacing?

Cabinet refacing is a method of updating your cabinets without enduring the expense and hassle of ripping out the old ones. It’s different from simply painting over the old cabinets. During refacing, workers remove doors and drawers, sand down all the original cabinet surfaces, Read more

Welcome to the Neighborhood!

Posted on May 01, 2018 by Greg Louie

Recently, I discovered an app that allows me to interact with people in my neighborhood who are looking to buy or sell things like electronics, furniture and clothing. The concept isn’t exactly groundbreaking (craigslist has been around for a while, after all), but there’s something about this app that sets it apart from the others I’ve tried: the community aspect. Since everyone who uses it lives and/or works in the same area, there’s a real sense of fellowship in the interactions I’ve seen. I mostly use the app to share Diamond Certified companies with neighbors who have specific needs. For example, if someone is looking for window coverings, I’ll give them a link to a nearby company’s Diamond Certified Company Report page—it makes them feel confident in my referral and I usually get thanked for my advice.

Spring Training for Your Team!

Posted on April 01, 2018 by Greg Louie

Spring is a season of renewal. In nature, new grasses grow, flowers bloom and birds nest. For consumers, moods brighten, home improvement projects are planned and winter-delayed health appointments are booked. For company managers, it’s a time to achieve performance numbers, optimize employee skills and generate more referrals.

For the Giants and A’s, spring is a great opportunity to work on perfecting the fundamentals. As the MLB season gets underway, I can’t help but reminisce about my own history with America’s pastime. Here’s something you might not know about me: from the age of 19 to 25, I was a semi-professional baseball player. It seems like a lifetime ago, but it’s true—I played on a number of tournament teams that competed across the United States and even played against international teams like Australia and Japan.

The Making of Your Helpful Expertise

Posted on March 01, 2018 by Greg Louie

The other day, I watched a documentary about the making of Pink Floyd’s groundbreaking 1973 album, The Dark Side of the Moon. It’s an album I’ve heard countless times over the course of my life, but as I watched the band members go into detail about the techniques they used to record those classic songs, it occurred to me that I only knew part of the story. Sure, I know most of the words to “Money,” but I didn’t know that in order to achieve the cash register sounds at the beginning, they had to stretch their reel-to-reel tape across the studio to make it fit with the song’s unusual time signature.
