Precision Building Services is a roll model contractor and professional in their trade. We used their services for post construction window cleaning, frame detail, pressure washing and buffing up our polished stainless steel. Michelle did a walk around of our commercial building with us and explained and educated us on each process she will be completing to give us the best results for each of the services we required. She provided a detailed contract which I've never gotten from any other companies I've used in the past. Her crew was respectful and professional and they delivered their promises in the time required. Precision will be our go to exterior building cleaning company.
