Our estimates are always based on the layout we are provided with. We always carry out actual field measurement once the cabinets are in place. In order to ensure accuracy, some cabinets are templated subject to the curvature of the layout. The actual field measurement/templating may alter the price. We will also need the sink and faucet selections Ė actual sink/faucet or the templates. It is important that we know the sink manufacturer and model number so that the sink cut out can be done. We also need the faucet information because drilling the holes for the faucet is much quicker and easier if itís done at our fabrication facility rather than at installation.
