"I've had this alarm now for 3 years and I can honestly say it's the best investment I've ever made for the peace of mind it's given me-on holiday, when I'm out, and when asleep in bed at night." S.L. of St Werburghs

"Colin installed our burglar alarm system some 17 years ago and annually maintains it. He provides excellent after care service, is prompt and efficient. Would highly recommend him to future customers." C.C. of Stoke Gifford

"We inherited the burglar alarm system (and Colin) when we moved in 8 years ago. Colin has maintained the system very efficiently which we were heartily grateful for when someone tried to force a window one night. The alarm went off and no-one got in. This has been worth its weight in gold for this incident alone but also for our continued peace of mind.." S.B. MSc BSc of Hambrook

"I am writing to inform you of the good service I have received from my intruder alarm system fitted by yourselves...the system is easy to operate...the installation is unobstrusive...in the two years I have been using it I have not had any intrusion since the alarm was fitted, this could be due to the deterrent effect of the prominent sounder units on the front and rear of the property...along with your maintenance programme, this has proved a most satisfactory system." A.C. of Keynsham

"Just to let you know how pleased I have been with the security system you have installed for us...the service you offer is second to none, and we are happy with the back-up servicing arrangements. Keep up the good work." M.B. of Kingswood

"Since you have installed one of your security systems at my bungalow, I now have peace of mind...as sometimes I work nights or long shifts...I wouldn't think twice about promoting your system, I would recommend this system to anyone." S.W. of Yate

"Just a few lines to say, how pleased I have been with my alarm and also the back up service you provided during the last nine years. It was only 12 months ago that during an attempted burglary after removing the kitchen window and entering the property, the alarm was activated which foiled the intruders." P.S. of Hanham

"...I asked the engineer to come and give us a quote...he discussed with us the system we required and very promptly fitted it...few months later we had an attempted burglary on the garage but due to the excellent system they were unable to get anything...we have been extremely pleased with our system - both the way the system had been fitted and it's reliability. We would recommend Masterguard to anybody who wants their house to be a safer place." J.J. of Southmead

"I am writing to tell you how satisfied I have been with the Security system you installed in my house some years ago. You took so much trouble to ensure that the system was adaptable, so that different parts of the house were covered & yet we could move freely within certain areas. Your after care has been equally efficient. We felt much safer with the System installed, & now I am on my own I am very grateful for the security I feel." M.M of Bishopston
