Sam and his team were excellent from start to finish. Sam advised us the best options possible with minimal damage and we then took on board his comments. We asked Sam to carry out the work and his team were flawless. Faultless job and left the place clean and tidy. Truly are a great young bunch of hardworking lads

Top job by Siren, couldn’t of asked for a better service. Initially only wanted CCTV for our home but ended up with the works, full cctv, intruder alarm system and a fire alarm system. Their work was such a high standard with top of the range systems used. The customer service was a just an added bonus for us, giving us confidence for our safety within our home.
