Estimating and design Takeoffs are billed by the square foot or by the hour. Residential projects are normally billed by the square foot. Large Commercial & Multi-family projects (where footages can be astronomical) are billed hourly in order to give our customers the best possible price. Our charges are based on US dollar. It depends by nature of the task. We accept payments after work done by Check, Visa, and MasterCard. Contact us today and let us know how we can help you. PAY ONLY IF YOU ARE SATISFIED.
