We have over 15 years experience specializing in residential audio, video, and security camera installations. From designing, installation and consulting, we provide a variety of high level Home Entertainment services. All work is performed by the owner.

"Joel is wonderful to work with! We converted a semi-finished room in our basement into a home theater. Joel worked with us on how to best layout the room and installed the sound system/speakers, projector, screen, lighting, and sound panels. Joel helped us pick the best equipment for our space and within our budget. When it came to installing, he has an almost obsessive attention to detail in the best way. He saw that the screen was 1/16th of an inch off level. I never would have noticed, but he made the adjustments to make it perfect. All of his work was like that - the details are perfect. The work went fast and we could not be happier with the results. The picture is big, bright and so clear. The sound is so crisp that you can hear birds fly over your head in a movie. You feel like part of the crowd when watching a football game. It really is an amazing set up. If you are looking to install a home theater, Joel and Every Man Home Entertainment is who you should hire."

Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

Award winning! Vintage Security provides monitoring services and security systems to over 19,000 customers throughout the Northern Virginia, Washington D.C, and Maryland areas. We offer a complete line of hardwired and wireless equipment to protect your home and/or business. Vintage Security skilled installers and technicians will treat your home and/or business as though it were their own.

"I have been on this system for 3-4 years. The initial installation went ok, but the overall functionality and reliability of the system is poor. The basic alarm system works when you manually arm/ disarm it through the app or keypad. However, the alarm cannot be set up on an automated schedule, and NONE of the connected automation features work - lights, outlets, blinds, etc. I purchased the recommended products that the company promised would seamlessly integrate into the system during the sales pitch, but none of them work. They have sent technicians out a couple times but, even after installing bulky repeater boxes in about half a dozen outlets, the system cannot connect. I have submitted several tickets, but Vintage just closes them out and suggests that I self troubleshoot. Alternatively, I can pay for an Automation Maintenance package and they will send a technician out. Bottom line - their system is nothing more than a 1990's alarm with a keypad and phone app. They dont deliver on what they sell, and they try to charge extra for support that should be included."

The electrician Tim arrived on time and carefully ran a few tests to determine the problem while describing to me what he was doing. It turned out to be a bad wall switch which he replaced with a new switch I had on hand. I will call CET again the next time I have an electrical problem."

At Roof Right, Inc. we have realized customer service and trust are poorly lacking in the roofing industry. That's why our roofing company takes pride in our exceptional service which includes showing up when we say we will, providing a thorough 17-point roof inspection, listening to you so we can make a quick and and thorough diagnosis of your (roofing) problem and cleaning up after ourselves as we work. Additional phones - (877) 778-6844, (410) 374-5923 Locally owned & operated. Financing available. Award winning.

"Contacted Roof Right for an estimate for having two old, leaking skylights removed and subroof and shingles installed in their place. I was quickly contacted by Roof Right to set up and appointment and Randy came by to take a look and give me an estimate. He was courteous and professional, easy to talk to. We thought their price was fair and had a good reputation so we hired them. Scheduling was easy and the crew was there when they were supposed to be. The crew was very nice, courteous and cleaned up after themselves. They worked quickly and efficiently. Payment through their portal was very easy too. Overall very happy with the work and would hire again. Thanks Roof Right for an easy process and a job well done."

We have been in buisness since 1962 servicing the baltimore area. We have been voted baltimore's best electrician 8 times by baltimore magazine. We take pride in returing all phone calls the same day and many jobs completed the same day or shortly after the call for service comes in.

"Work as good but lack communication and the estimator was only at my home for 30 minutes before and said full service for my electrical which I already knew the work done was excellent but the generator repair was forced on me and is now wired but still doesn't work I was told to contact the generator company for service it won't let me post photos but all in all work was a 5/5 service was well below a 0/5"

Home Automation questions, answered by experts

One significant drawback of home automation is the increased risk of cybersecurity threats. With more connected devices in our homes, there's a greater chance that hackers might try to exploit vulnerabilities to access personal data or even control your devices. If you don't secure your smart gadgets properly, they can become entry points for cyberattacks, risking your privacy and safety. Moreover, technology isn't perfect. Sometimes, systems can malfunction or experience connectivity issues, disrupting your daily routines. The upfront cost of buying and installing smart devices can also be a hurdle for some people. 

Yes, HVAC professionals can install and integrate smart thermostats for energy-efficient home automation.

A comprehensive smart home system can be really attractive to buyers and increase the value of your property. Components such as a smart security system, smart lawn and garden systems, and smart appliances can all drive up the value of your property.

A potential weak link in any security system is poor connection strength or dropped signals, particularly in the case of a fully wireless system. You also want to ensure a reliable connection to get a hold of your service provider quickly. Also, you should exercise caution when handing out sign-in credentials to people outside the household.

Smart windows can last anywhere from 10 to 50 years. It depends on the type and brand of smart window you choose and how much usage your windows get.
