Security: Our commercial carpet cleaning does not provide this. If there is a concern about the door remaining open while we do the work, you may want to consider having your own security personnel keep an eye on the entrance.
Insurance: We carry commercial liability insurance (2 million policy) and can provide documentation. If you require us to hold comprehensive coverage on our commecial vehicles however, this is a deal breaker. But, we agree to release you from liability for damages and/theft related to our property.
Forms and Contracts: Some property management groups have certain protocols they must adhere to related to billing, forms, contracts, and other paperwork. If this is the case, let us know in advance and we will see what we can do. For our part, we have never required customers, either commercial or residential, to sign a contract. Our company has never been sued or had an insurance claim.
How far we can go: We can go a long way vertically. Gravity being what it is, there is big difference between pulling water and air downward from higher elevations than pulling upwards or across. If we can get within 75 feet of the inside stairwell, 300 feet of total hose lets us do the 8th floor of a typical highrise depending on the span of floor itself. If we can get within 25 feet of the stairwell, we can realistically clean the 11th floor! I would consider putting another 50 foot length on too (3 more floors), but with less certainty.
