Great company with innovative ideas and a prompt, reliable staff. I’ve worked with this company for over 12 years and would not hesitate to recommend them. The best in the business.

-William G.

I’m very pleased with CSS. Also, the technician, Damian, who came out to install was EXCELLENT! He was knowledgeable, and very patient with my many questions. He was also very respectful of my new home (gentle, always covered his shoes, etc.). I am grateful!

-Linda V.

Damian was great! Consummate professional who swiftly identified and resolved the issue!

“I have had a great experience with CSS thus far!

-Rachel L.

We have always appreciated our experience with CSS from the sales team with Dave, our interactions with the technicians – especially Jeff, and Melissa with helping us schedule and keep things moving. We have completed 3 pretty extensive projects with CSS and have been extremely satisfied and will only be looking to CSS and their expertise when we have our 4th project. Thank you again for your partnership and professionalism.

– Christopher P.

First class group of people! Christopher has the patience of a saint!!!

-Marty S.

It has been such a pleasure working with everyone from CSS. They are a top-notch company.

-Kristen R.

I wanted to take a moment to commend a technician who has come out to our house twice this past year. Allan did the set-up of our alarm system in February 2017 and came out to change the batteries last Friday. He was friendly, professional, and knowledgeable during both visits! He answered many questions and explained things so we could understand the technology better. He is an asset to your team!

-Laurie F.

The service was great! Damian explained everything thoroughly. He showed me how to operate the security alarm and explained how the WiFi enhancement works. Damian also did a good job of explaining the fees, including Montgomery County’s security system permit fee. I was very satisfied!

-Jason W.

I have had a very positive experience with CSS both with installation and monitoring. I would so far recommend them but we have only had the services for a couple of months. Everyone has been easy to work with and the monitoring company is very prompt in addressing any issues with the alarm. The wi-fi booster also works great.

-Heather S.

Christopher was so helpful and patient with us over the phone! He is a great customer service representative. Thank you so much!

-Evelyn B.

Melissa, I couldn’t let the day end without thanking you for coordinating the communication with David as well as scheduling Damian to install our new Sonos sound bar today! I really appreciate your attention to the emails as we went back and forth with questions and answers! Of course, we are thankful for David’s help in selecting the sound bar and once again, Damian was the rock star! He spent the time necessary yesterday to make sure that every part of the system worked perfectly before he left and is always professional, patient, and skilled in installing TVs and sound bars! We will always refer friends to CSS and speak highly of the skill in every area of the technology that makes our house communicate so smoothly!

-Carole T. and Bill S.

Thank you to Damian for the wonderful service he provided on Friday, November 10th! I appreciated his professionalism and awesome service. Due to his professionalism, we plan to utilize CSS is the near future; as well as spread the word about Damian and CSS to our family and friends! As you know, customer service is not what it once was in the United States, therefore; we were ecstatic to receive such classy service provided by Damian. Again, thank you LOADS!

-Sheila C.

From start to finish this was a wonderful experience. David and Melissa were both polite and made the scheduling process easy. Jeff was on time and very knowledgeable and friendly. The bill was fair. The staff was patient and understanding of my needs. 5 stars! I highly recommend!

-Barb K.

Excellent service!

-Denise S.

CSS has been great from the very beginning.They originally installed my alarm system and they also installed my IR reader kit. Both processes were smooth and seamless. I look forward to working with CSS in the future!

-Tiffany M.


-Bill U.

 I want to offer my compliments for the wonderful and timely completion of this project. The crew was efficient, took the time to let us know each step as they completed it and was just very personable. The clean up was an unexpected plus! We appreciate working with a great crew.

– Sherry A.

Damian has just left our home and I would be remiss if I didn’t send Melissa an immediate thank you for the wonderful work that EVERYONE did at CSS to make this technical system work!  We appreciated working with David to plan out what we needed to have satisfactory internet service in our home, he had the perfect solutions for all of our needs and we would hardly wait to see what the “frizbies” could do to supply us WiFi service….. Damian mounted the TV perfectly this morning and turned on the frizbies and everything is working perfectly!!!!  This is pretty much a dream come true. And without Melissa’s scheduling of David, Damian and frequent help and advice, nothing could have happened!

Thanks to all of you for your professionalism, patience and wonderful service, you all have supplied our home with just what will make watching movies, tv, and using our computers finally work smoothly.

-Carole T. and Bill S.

“Matt provided very accurate and professional service. He made sure I knew how to operate all components and he sent instructions to my email!”

– Rosemary

Allan was absolutely fantastic! He was professional, friendly, kind, and very intelligent…He taught me as he worked and answered every question I had…I’d give him an A+++ Thank you!!!

-Linda R.

Damian was a pleasure to work with and was able to solve the problem with our receiver. He was professional and courteous, and explained everything clearly. He even stayed a bit longer to adjust the sound in our surround sound system and made sure it was providing the best possible sound experience!

-Jill S.

Allan, the technician, was prompt, friendly, helpful, and efficient. It was a positive experience to have him in our home.

-David Q.

CSS did a great job preparing before they arrived. All the parts were there and ready to go. The tech, Jeff, was extremely knowledgeable, improving my system better than I envisioned. We could not be happier with the CSS team!

-David E.

Connor and Melissa, thank you for the help with our system upgrade. We really appreciate the great service over the last 15 years. Thank you very much! Looking forward to many more years as a customer.

-Sean S.

Allan, the technician you sent over this morning, was amazing. I wanted to let you know what a great technician and person Allan is. Please thank him again for the fantastic service. Allan has my highest recommendation. Even though Allan couldn’t move the piece, he had some great ideas about how to work it all out—He was conscientious, careful, thoughtful, and very kind. Your last service person, Jeff, was great as well. You have a fantastic group!

-Nairi B.

I have been dealing with Melissa Scott, she is simply terrific. She is always available. In fact, I emailed her a few minutes ago and she responded to me quickly on a Saturday night. Honestly, if I was running a company today I would steal her away based on my experience. Based on my contact with David Mimms I later asked him if CSS would also help me with my Easton home, which was under renovation at the time. Later on, I met David S. Matt M., Jeff D. and the rest of that team who worked on both of my homes. All are very smart, nice and competent people. I have experienced some issues such as translating certain specifics about my Easton project that were discussed during pre-install Easton sight visits and making it all happen exactly as planned months later via the install group. However, despite these problems, the manner in which Melissa, all your “Davids”, and the rest of your team handled things made it all much easier to deal with and move on. I actually enjoy seeing your guys when they show up. Anyway, my takeaway is that you must hire well and have a good culture — but remember if I decide to build another company again I may steal a few of them 🙂

-Hugh P.

Just wanted to say that we are very appreciative of the great job your service technicians did. They were very knowledgeable, thorough, and professional. We have not had a reoccurrence of the problem since!

-Sharon C.

Allan, CSS, just completed a service call at our home. He was knowledgeable, efficient, customer focused and extremely polite, Thank you for the great service! CSS is fortunate to have him on their teams.

-Cynthia S.

Matt did a fine job of installing our TV!

-Roger S.

We were really impressed with the work and quality that Matt did at our house today. We could not be more pleased with the results. Thank you again!

-Jude M.

Chesapeake System Services provided awesome customer service today. One more reason to stay with them as I have done over the last 6 years! I highly recommend them. Very professional and awesome customer/tech service! 5 stars!!!!! This alarm company is #1 in my book!

-Jill H.

We have had the pleasure to work with CSS for the past few years and we were extremely impressed with the entire process from beginning to end. Our most recent project was at our new Three Dog Parcel Facility in Jessup, MD. The quotes were competitive and accurate, the install was quick, the quality of work was excellent, and the system training was complete and easy to understand. Since the install, we have had a couple questions and the CSS Customer Service Department has responded quickly and answered all our questions the same day. We highly recommend CSS for any Commercial-Based or Home-Based Security Projects. Great company to work with!

-Dan M.

Technician Allan, was very knowledgeable, courteous, and took the time to explain equipment installed in my home. He gave me a quick overview, that was very helpful. He explained possible new options for security and safety.

-Joanne F.

Technicians, Matt and Allan were very professional, and friendly.

– Michael M.

Damian did a very good job. He quickly analyzed the problem and replaced my two outside speakers and made sure that they were working properly!
