"I switched from another company to Security One, they use the same equipment. They had to come out and recode everything. I simply switched because of the financial benefit. I have only had them for a few months, and I haven't had any problems with them. They save me some money every month. When my alarm went off, they did call me."

"You asked for details - you get details. I have internet security on my laptop; I am not a novice computer user. I frequently scan my computer for viruses and delete history and temporary internet files. I am cautious in downloading files onto my computer. I frequently can "fix" issues on my computer myself.
However, my computer not only began running very slowly no matter what I did; I frequently had to reboot/reset my wireless router. Internet pages I visited frequently became inaccessible to me. Downloaded games (jigsaw puzzles, hidden object games) no longer were accessible even though they were in correct programs files on my hard drive.
In desperation about 10:30 one evening, I googled "geek squad." In addition to finding the site for geek squad, I also saw a site to Geekatoo. I went to their website because they provide in-home support, which I reallly wanted. I forget where they are based, but must be on west coast since they are 2-3 hours behind us here in the eastern time zone. Read their entire website, then chatted onlline with a customer service rep who politely answered all my questions, reiterating information contained on their site: all techs are fully vetted regarding their credentials and all have undergone criminal background checks. The rep said they do have geeks in the Chattanooga area and she would arrange for one to come call me to set a time to come to the house. She told me that I would not have to pay the "geek" anything; I would pay Geekatoo and Geekatoo pays the Geek. I asked her what would occur if Geek were unable to fix my problems. She said "you pay nothing to us if your problem is not resolved." So, what happens if I expect to pay $xx, based on what I think my problems are, but Geek finds more troubling issues with my computer or it needs parts, etc. She said, "the Geek will let you know what the problems are and you have the option to stop the service at that time, or continue" The service sounded like a win/win.
Twelve hours later (about 10:30 the following morning), I received a call from Daniel Eilers, a local Geek with Geekatoo. We talked briefly and arranged for him to come to my home at 4:00 that afternoon. He arrived promptly at 4:00. I told him how my laptop had been lately and my growing frustration with it. He ran programs he brought with him and ran diagnostics and spent 2 hours at my computer, doing one thing and another. He patiently went through programs on the computer with me to determine if I wanted to keep them and how deleting or retaining them would (or not) affect the performance of my computer.
When he left my computer behaved as a new one. All games which had disappeared had returned. The computer ran smoothly and quickly. Incidentally, I have not been knocked off my internet service either, not once, since he worked his magic.

"That's the name I am vaguely familiar with; it's a home security company that is license to ADT franchise or dealer if I am correct. They were very good. They were prompt; they were quality. The individuals move their business. They were very timely and it was a good experience."

"Excellent work. We purchased natural cherry cabinets in shaker style, with the panels made of solid wood rather than veneer. That is more difficult work, as each panel has to be constructed from several planks. Moreover, the clear finish would leave any flaws more visible. Simply put, the doors are beautiful--flawless in both construction and finish. They are similar in quality to custom cherry furniture we own."

"Yvette Pringle provided courteous and professional feedback to me when I called to inquire about a new home security system. My situation was unique because we were trying to find something that would work for a deaf person. I appreciated that Yvette did her research to find out what would work. She also offered different options in terms of a package and plan. We did end up going with another company, but I really did want to recognize Yvette for her work. She was very polite and helpful.

The average cost of a home security system is about $700, ranging from $280 to $1,150. Costs to consider include equipment, surveillance fees, and other additional features. Cost factors that determine your system’s price include the type of security system, materials, labor, activation fees, monthly fees, and permits. Additional features and upgrades may include:
Video surveillance monitoring: $40–$65 per month
Smart home locks: $150
Smart home lighting: $15–$90
Smart smoke, fire, and carbon monoxide alarms: $35–$100
Smart thermostat: $130–$500
Door installation usually takes three and four hours, including removing the old door and frame, fitting the new door and frame in place, shimming it to make sure it’s perfectly level, and making adjustments to the hinges and locking mechanisms to ensure proper functionality. A door-hanging professional can replace an interior door in between one and two hours. Door installation will take significantly longer if your installer needs to create a wall opening, and it can take less time if the existing door frame remains.
The average cost to install a door is around $1,100, but you could pay anywhere from $150 for a hollow-core interior door installation up to $2,000 or a high-end exterior door installation. There are a few cost factors to consider to get an accurate price, including whether your wall opening exists, the type of door, the quality and security of the door, whether you need to replace the frame, and the door size. You can expect to pay $150 to $700 for a standard 36-by-80-inch door and between $400 and $1,600 for an 80-by-48-inch door.
Yes, a home security system can be worth it for your peace of mind alone, but it can also save you up to 20% on your home insurance. The insurance savings will help defray the initial setup costs and subscription costs over time. Locations with higher crime rates also make home security systems a valuable investment, but it ultimately depends on your personal preferences and asset values.
It’s possible to install a door yourself if the wall opening already exists, but the work is rather complicated, and a professional installation is usually well worth the investment. For your door to work and close properly, you’ll need to shim and level the door frame in your wall perfectly, which can be difficult. Additionally, we recommend you always hire a professional door installer to place an exterior door, as mistakes during the installation process can lead to poor security for your home.
From average costs to expert advice, get all the answers you need to get your job done.

Whether you’re installing a new door or replacing an existing one, the cost of door installation varies based on location, door type, framing needs, and other factors.
