What People Are Saying
“An Outstanding job was done by this company! I can’t believe the difference in what I can do and what these guys do! Very friendly and professional. Selah makes it super easy to get an estimate and book a time. Really as simple as counting your windows. Justin and Michael came out to do the work. I work from home so I can’t have a lot of noise or disruption - no problem with these two. Both were so friendly and really did a fantastic job on my place I already got them booked for next June!”
“Blake and his team set up our Christmas lights this year and they look great! We live in CDA and they arrived timely and went above and beyond to make our house look great. They set up our timer so the light go on when we want them to and everything. He was professional and kind and the Christmas music was a great touch.”
“This is our third year using Double Diamond Window Cleaning to hang our Christmas lights, and they always do an amazing job! The lights are custom to our home and look perfect every time. This year we decided to change the color, and it was no problem at all — everything was done quickly and exactly how we wanted. Cyris was our service expert this year and was fantastic — very communicative, prompt, and kind. Highly recommend Double Diamond for professional, beautiful holiday lighting!”
