ServiceMaster Restore of Johnstown Warns Homeowners to Practice Fire Prevention Leading up to the Holiday Season

After today my projects are complete as best as I can determine. I am satisfied with the work performance by all of the workers and there were many. Especially, Mike and the other Todd, who work effortlessly together and are two of the greatest assets, including the other Bill who steadily gets the job done without a sound. You've assembled a winning team who are respectable, informative when asked and very deliberate and patient. I cannot believe that the beautiful work was completed in such a short period of time. Again, thank you and God bless.

Lois said "it was an amazing transformation. The guys were very nice and always cleaned up at the end of the day. Thank you estimator Bill Hanik and carpenter Jeff Walker for a job well done."
The employee that you put in charge of cleaning the School Hall gave me a walk-though today. He was the maintenance man at St. Clement 40 years ago when I was the Associate Pastor there. Mary Frances Bodek, the Hall Manager, also came this evening to check out the hall. We both agree that the hall has never looked so clean! Your Supervisor did a fantastic job getting the workers to clean the entire downstairs to our great satisfaction. And we made it with one day to spare! I signed the completion form and will take it to the Post Office in the morning. Thank you for the outstanding job on making our social hall and all the rooms on the bottom floor look as though they went through a renovation instead of just a cleaning.
Windber Research Institute, Director of Maintenance
Working with Mark Sirko was a true pleasure. He was always professional, pleasant and helped me understand all facets of the project. Mark went well beyond the call of duty in making the new work blend with the old…The new tenants are extremely pleased with the outcome as well.

Mark and Mike are very skilled carpenters and always presented themselves in a neat and professional manner and to put it simple, they are all around just great guys. Because of them, I feel this job went as smooth as it possibly could have. They helped me through what I thought was going to be a nightmare…I will surely recommend your company to anybody, commercial and / or residential and keep JCS in mind for and future work that I might have.

We recently had a pipe freeze and burst in our home creating a good bit of damage. You were assigned to clean and restore our home to it former state. I just wanted you to know that we have been quite pleased with this process and feel that we have been treated well.

Dear ServiceMaster. I want to thank you for helping with the problem I had when my furnace blew black soot all over the inside of my house. You did a wonderful job, cleaning people were very friendly and prompt.

What I liked most was the incredibly fast response and performance. This made it easy to get the apartment cleaned after the move. They did several rooms, stairs and closets with no problems. They were very attentive! I would recommend and use them again!
