"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."

"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

It depends on your specific needs. A security system typically includes alarms, sensors for windows and doors , and 24/7 monitoring services, offering comprehensive protection with immediate response to potential threats. Cameras, on the other hand, primarily provide visual surveillance and evidence collection. A security system is preferable if your primary concern is deterring intruders and receiving real-time alerts. Cameras are ideal for monitoring and recording activities but might offer a different level of active protection. In many cases, a combination of both—a security system with integrated cameras—provides the most robust home security solution, offering prevention and documentation.

Insurance companies weigh the amount of potential liabilities on your property to increase (or decrease) the cost of your home insurance. They will use several factors to decide if there are more chances for peril or injury to take place at your home. These factors include your location (whether you live in an area with high risk for natural disasters), the age and condition of your home, and whether you have any “attractive nuisances”—features that both increase the aesthetic of your home and potential for injury—like a pool or treehouse. 

In general, keyless door locks are considered safe, and their security depends on the type and quality of the lock. They cannot be picked like a traditional lock and often include added features like biometric access, PIN codes, and smartphone connectivity, which can make them more secure. However, they are not without risks. Potential vulnerabilities include hacking for Wi-Fi-connected models, battery failure, power outages, and technical malfunctions. To maximize security, it is important to choose a reliable brand, stay on top of software updates, and perform regular maintenance. While the risks are different, keyless locks are not considered more dangerous than traditional locks.

A deadbolt differs from a regular lock in its design, construction, and security level. Regular locks are typically used for interior doors, such as for bedrooms and bathrooms, and provide minimal security. They are easy to install and use, often featuring a simple locking mechanism on the inside. In contrast, a deadbolt is one of the most secure locks you can install on an exterior door. Its internal construction is designed to withstand significant force, adding a crucial layer of security that can deter intruders. While deadbolts may be more expensive and complicated to install, they are cost-effective for the security they provide and are built to hold up to wear and tear.

Technically, there isn't a difference between safe rooms and storm shelters. Both are designed to protect you from storms and extreme weather events. People often use “safe room” when discussing a shelter inside a building and storm shelter when talking about a detached unit. 

Additionally, a safe room is understood to have more functions than a storm shelter. You may seek shelter in a safe room when you believe an intruder is in the home or when under another type of threat.
