Great company! This company has been providing security services to a few of our sites and we have been very happy with their services. The guards conduct themselves is a very professional manner, it is easy to contact a supervisor if there are any questions or concern. They provide us with daily reports of the shifts. It’s been a pleasant and welcome difference dealing with this locally owned company vs. the large corporate company we've worked with in the past. Stonewall cares and you can really tell! Thank you for your service guys!
Stonewall Security took over our security issues at a moments notice and did a great job. Very responsive and flexible and met our needs at a moments notice when we had to change our plans.
I used Stonewall's security service because we were having too many trespassing and loitering on our property. They were super easy to talk to and get a quick quote from. The owner is very friendly and hands-on - this made us feel extra secure. Since their security guard's presence, our building's trespassing and loitering problem has significantly decreased. The guards are friendly and professional. I would highly recommend Stonewall for anyone seeking security services in the Seattle area.
We have used Stonewall for our overnight security at our local art festival for more than a decade. They have always been very responsible, attentive, friendly, and thorough. We wouldn't go with anyone else!
Used Stonewall a few times to request a vacant property to be walked during the night time. Easy to setup, even last minute, simple straight forward pricing, construction crew stated the security guard was professional and clean. Saved this company's info because unfortunately they are necessary these days when dealing with properties.
Very professional and service was great, I will definitely be booking with these guys again when we come to seattle for our next project!
