I had mold and algae on my vinyl siding. I had the the "mold busters" system done by A-Tech Exteriors on January 6th, 2011. The difference is amazing. I'm so glad I had this done. The work was quick and professional. I recommend this service to everyone with vinyl siding.

Hear from our customers!

Dear A-Tech,

I am writing to tell you how pleased we are with the restoration you did of our driveway and front walks. I was sorry to be away while you did the work, because it seemed to me to be an interesting process. However, the restoration was done in a professional and workmanlike manner, and within the time constraints of our agreement. The "brick" trim was the crowning effect, and beautifully done. 

Thank you very much,

​I wanted to take a moment to let you know how pleased I am with the job you did at my house. When I realized it had been two years since I had my exposed aggregate patio and 100 foot walkway poured, I didn't really know what to do to renew and seal it. What a difference it makes to have a superior product used and professional application (not to mention the fact that it was all finished in one day, perhaps the hottest day of summer)!

To give you follow-up on the crack in the sidewalk you fixed, all is well and it looks great. You not only showed up when you said you would, but also demonstrated outstanding commitment from set-up to finish. I really appreciate that in itself, as my time is valuable and so often contractors fail to recognize that.

​I hope you'll feel free to use me as a reference in the future and keep me in mind for the rest of my concrete requirements in the future.

Thanks again for your outstanding work.
