The cost of concrete or stone patios, pool covers, landscape curbs, walkways or driveways depends largely on the finish of the concrete or the type of stone used. Our model uses the same profit margin as the Softscape installation. It is important to use an overhead recovery model to estimate and price labor. Overheads are overheads, either for planting or building a wall.
If you base your prices on a material profit margin, don't forget that harsh conditions require a lot of equipment and that you need to recoup the cost of that equipment over its lifespan.
