A reliable wood removal service should always have valid insurance, as wood removal may cause a lot of damage to property and workers' health. If a company doesn't have insurance and somebody or something is damaged, the customer has to pay for everything. The insurance company of the wood removal service has to send all the certificates to the customer upon request. Certificates provided by other people aren't valid.
Companies that are members of the Better Business Bureau usually provide good services, as it is difficult to receive accreditation from that organization. Some companies that aren't members may have received a good rating from the organization, which is also a good sign. A good wood removal company should also have a good reputation. Customers can check the company's reviews on many consumer review websites.
A reliable company should have many years of experience in the area. This means that it provides consistently good services. In addition, good companies are usually members of reputable trade associations in the field.
A good company should have mid-range prices that aren't too cheap or too expensive. Also, reliable companies always have a list of references that they provide to the customer upon request. Reliable companies never ask customers to pay them before the work is finished completely.
