"William was awesome. He gave me recommendations in different price ranges so I could choose within my budget (which was only $2,500). My home theatre is now a theatre experience, not just a big screen tv. Highly recommend him."

"Ed was very professional. He did an excellent job at mounting our televisions we were so impressed with his work the first time we hired him that when we purchased our new home we rehired him to come and mount all of our TVs in that home. I highly recommend him to anyone."

"Hey guys, I had an electrician from BriteBox, come to my house to investigate a problem I thought I had. As it turned he (Mark Henderson), the electrician pointed out while checking my electrical panel of something that could be gave down the road. We live in our homes oblivious to what lurks beneath the surface. It's almost, as if you need to take an electrician, along with you on your househunting endeavors. Too ensure the property you may buy is within code, certainly, if it's an older home! By the way he Mark, solved the problem with the original reason for the call!!"

Home Security Systems FAQs, answered by experts

Some but not all security cameras have monthly fees, depending on the specific camera system and the services offered with it, especially monitored vs. unmonitored security systems. Home security companies that offer monitoring services along with cameras will charge a monthly fee for monitoring and possibly for using the security cameras. Cameras that you monitor yourself as part of your own security system will not have monthly fees charged.

Yes, most pros encourage you to change your locks when you move into a new home. While the previous owner may hand you their keys, you have no way of knowing whether other copies exist elsewhere. Changing your locks as soon as you move in is a great way to ensure that you can enjoy new, fully functioning locks that will work with your unique key or code.

Although some pet doors allow easier access for burglars or stray animals, there are ways to make pet doors more secure. To increase your home’s security, choose locking or electronically activated doors, use additional motion sensor security cameras, and install pet doors on a wall where door locking mechanisms are difficult to access.

Window security film won’t prevent break-ins or stop your window from shattering from impact during extreme weather like hurricanes or tornadoes. However, applying security film is relatively inexpensive, and it can make breaking into your home significantly harder—often hard enough to deter burglars entirely—and keep your window from shattering on your floor after impact. For these reasons, window security film is often a worthwhile investment that helps protect your property.

Instead of a security door, you might opt for a heavy-duty screen door made from durable mesh, which allows better sunlight and airflow. Additionally, you could enhance security by installing strong locks on your existing door. A double-cylinder deadbolt provides robust security; however, be aware that some local laws prohibit them due to safety concerns during emergencies.
