Angi Review by Julie K.

Splaine is a terrific company that stands behind its work. John (who did the initial estimate) was very professional — punctual, responsive, etc. — and (unlike others we interviewed) did not try to sell us more than we needed. The installation was also completed in a professional and timely manner, and with surprisingly little damage to the walls and ceilings. We’ve been using the system for a few weeks now and it is super simple. I should add that we used ADT at our old house, and there’s no comparison. Great to use a local business, and highly recommend Splaine.




Angi Review by Sandra M.

I have been a very satisfied Splaine customer since 1999, when they installed the original security system on my new home. Sam Splaine met with me and my family and was a pleasure to work with. Have had several contacts with them since then and have always been impressed with their professionalism, promptness and courtesy.
