Excellent! By far one of the most well versed in the subject matter. We had a mice issue that was causing a number of problems. What struck me when I hired Guaranteed Pest Control Services, was just how meticulous they were in their inspection, planning and feedback. They were incredibly accessable, I felt I could contact them any time and they were responsive. In providing us an honest timeline our expectations were well managed. The first week we had no good results, the second week after the next visit the issue was solved. Even still they have offered to come back again free of charge to check and I have a 3 month guarentee. It doesnt come cheap as these things often don't but well worth the spend on aquiring the services of these superb professionals and genuinley nice honest people.

Very professional and efficient pest control. The building had mice for a very long time, even with all the effort possible to get rid it, but thanks to John I haven't found any pest activity in weeks. Recommend 100%

I did bed bugs treatment with this company. My house was fully infected I just got the number of this company from one of my friend after one treatment we got great results. And this guy is very humble. Thankuu very much

Great company, our house was infested by red ants all over the kitchen and rooms, after two failed treatments by other pest control companies we luckily contracted Guaranteed pest service, not only they got rid of ants but sealed all the gaps and crevices and on top we received a one year warranty for their job. John and his colleague were so polite and they cleaned the kitchen thoroughly after finishing their job,, am so thankful to both of them. Will definitely recommend this company to everyone.
