I have been in the construction businesses for 20 plus years, and can do anything you want. I have worked in many areas of construction for example remodeling spaces, painting, building structures and so forth. I am independent owned.

"Easy communication. I needed a bathroom exhaust fan installed where there is no attic access. The project included wiring and ductwork to the exterior as well as drywall removal and repair, and then finishing everything beautifully. The two-man team of Vasquez did as instructed and also fixed some old shoddy work that was in the way of the new duct and wiring. They used good materials and did good work at a good price. They were also very respectful of my home, keeping the mess contained and cleaning up after. I would hire again."

"These guys did the fire sprinklers for our home. They came in and did the project well. However, once they finished and finaled inspection, they are totally unresponsive. There's one fire sprinkler they never put a cap on. I've been trying for MONTHS to get them to put a cap on. They just shipped me a cap and said "do it yourself". I watched a youtube video, but something isn't fitting right, and I can't get the cap on. I feel it's not right that they can't even return to finish the job they started and assume that I need to become a sprinkler head expert myself and put on the cap. Hopefully after this review, they'll finally respond to me!"

Home Security Systems questions, answered by experts

Professionals optimize camera placement, integrate recording systems, and ensure tamper-proof security.

Your best bet is to install a bracket that secures to the bottom of the unit and the side of your house. You should still secure the AC unit in the open window using some of the other methods already listed, but a bracket is best to ensure that it stays put—both during operation and in case of an attempted theft.

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.

Each has its use, depending on the scenario. Security doors are primarily intended to keep people out of the home, while storm doors are used to protect the home from extreme weather. Both tend to be made from heavy-duty metal and may include glass panels to allow light to enter the home. Storm doors can feature mesh screens, just like screen doors, to allow for increased ventilation and to keep out pests. Security doors rarely, if ever, have mesh screens.

Security cameras do not need wiring if they are wireless, meaning they are battery-operated and can connect through Wi-Fi. You’ll need to change the batteries on a wireless camera and ensure you have a steady connection to Wi-Fi for video storage. If you have a wired security camera, you’ll need to plug it into an outlet or other power source and a DVR device.
