Choosing the Right Hardwood Floor Cleaning Product

DANVILLE — A hardwood floor is a big investment, and the best way to protect that investment is by employing proper care and maintenance. However, just any maintenance won’t do—it needs to be appropriate for the type of floor and, more importantly, the type of finish you have.

There are three major finishes used on hardwood floors: urethane, UV oil and oil-based. Each of these finishes requires a different cleaning product (or set of products). Urethane is the most low-maintenance of the three. For cleaning a urethane-finished floor, Bona® Hardwood Floor Cleaner is a good choice. Simply spray your mophead with the cleaner and wipe the floor clean.

Considerations for Choosing a Wood Flooring Product

DANVILLE — When choosing a new wood flooring product for your home, you’ll need to consider several factors to make the right decision. A good starting place is to consider the size and character of your household, as this will inform the criteria on which you’ll base your decision. For example, if you have an “active” household with young children and pets, you’re going to have very different criteria than a retired couple.

One of the most important characteristics to look for in a flooring product is durability. If you have an active household, you’ll want a floor that can stand up to wear—a dense product like oak or maple as opposed to softer wood like poplar or alder. Read more

Level Up!

The other night, I was watching one of my new favorite TV shows, “Black Mirror.” If you’re unfamiliar with the series, it features stories that explore the social implications of how technology might be used in the not-too-distant future. Usually, it’s about how certain technology can lead to disastrous situations when misused, but some episodes take a more optimistic perspective.

The episode I watched, “Nosedive,” is about a society where every individual gets rated on an app based on each encounter they have with a person or business. Their overall rating dictates their socioeconomic status and allows them to earn certain benefits. The main character is a woman who wants a high score in order to qualify for a luxury apartment, Read more

And although this impression can change during the course of an interaction, getting the first impression right gives you a huge competitive advantage. In the first four minutes, your potential customers are quickly answering these subconscious questions about your company: Read more

Making the Grade

Posted on August 15, 2018 by Matt Solis

In my family, August has always meant “back to school” time. Now that one of my daughters is in college and on the quarter system, she doesn’t start until September, but that doesn’t change the fact that August is still a great time to plan for the rest of the year. I think this is common for most families. People are back from their summer vacations and starting to plan their projects for the upcoming months. Whether it’s major car repairs, home remodeling jobs or health checkups they’ve been putting off, this is the time of year when people make the calls.

If you qualify for Diamond Certified, you’ll be in a unique position because you’ll have access to tools that make your company stand out from your competitors and help you capture the best consumers who will keep you busy through the typically slower months of the fall and winter. Read more
