There is a lot to be done when it come to hanging and finishing drywall. My crew and I are well aware that perfectionism is needed when it comes to our customers. We hang the drywall in a fashionable manner. We also finish the drywall in the best way possible. If you need the job done quick and perfect, we are the men. Many companies will do the job but very sloppy, we on the other hand know what our customers are worth. Each crew member has at least 5 to 10 years of experience working with drywall. This is my own business.

A Full Service Electrical Contractor basing future growth on customer satisfaction. For us it's " Quality * Integrity * Customer Service! "

"We hired Dale at Pro Precision Electrical to replace our circuit breaker panel with another 200 amp panel since our old one was not on the approved list of our homeowner's insurance. Dale responded quickly with a very reasonable quote. He showed up on time with two workers. He had to enlarge the opening a little for the new panel and as a result had to patch the drywall, but he still stuck to the original quote. We had a small issue afterwards with our microwave tripping a circuit breaker, but Dale came back out quickly and fixed the problem. Overall, we were very pleased with his work and price and would definitely hire him again. He is now my go-to contractor for any electrical work I need done."

FAQs for alarm or security system installation projects in Key Largo, FL

If you terminate your security system before your contract ends, you’ll likely have to pay a cancellation fee—often a percentage of the remaining contract balance. To avoid these fees, consider choosing a brand that offers contract-free plans, like SimpliSafe or Vivint. You can also negotiate with your provider to see if they provide pro-rated cancellation fees or special exceptions.

Paying for a security system is a valuable investment because it enhances your home’s safety and deters criminal activity. With millions of property crimes each year, having robust security measures helps protect your property and might even lower your insurance premiums. It's a worthwhile investment for lasting peace of mind.

The average cost to install security cameras ranges from $125 to $3,500, depending on the amount, type, and placement. To install a complete setup of four cameras, homeowners can expect to invest an average of $1,300 for labor and equipment. Installing multiple cameras gives you comprehensive coverage of vulnerable entry points and enhances overall property security.
