"Antonio was great. I had 2 ceiling fans installed on a 15 foot high pitched ceiling. The fans I purchased were meant for a ceiling with a much smaller pitch so they were not able hang straight as is. I thought I would have to wait and buy some additional hardware to complete the job but Antonio clearly communicated with me to show me why they wouldn’t work and talked me through a few ideas he wanted to try to make it work. It took a bit more time but in the end he was able to make some cuts and holes to the fans and they worked out great in the end. He saved me some time and money so I was happy to leave him with a tip. "

Home Security Systems questions, answered by experts

Any type of dead bolt lock provides the highest level of safety for a single device. However, it’s also important to determine a lock's grade. Locks can come in either Grade 1, Grade 2, or Grade 3, which indicates how durable it is and if it’s constructed solidly. Safety experts recommend choosing locks based on Grade 1, which offers the highest level of durability.

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.

Thieves can open almost anything with enough time and the right tools, but they also prefer easy targets that are unlikely to get them caught. Forcing open gates is loud and difficult, and to be able to open one electronically requires extensive knowledge of the system, which most thieves don't have. Electric and other security gates are great deterrents because the thief will move to an easier target. If the thief is determined to enter your property, they will most likely find a different entrance point.

Yes, adding ease of use and remote access via smartphones.

Home automation costs an average of $1,000, and most projects fall between $200 and $2,000. The total cost will depend largely on the level of automation you want in your home. High-tech, all-inclusive systems can cost well over $10,000 for larger homes, so most homeowners set a budget and then provide that to an expert to get the best results. You can also opt for DIY home automation technology for between $100 and $500, but the scope and interaction between products are usually limited.
