After the experience I had with Lancaster, I would not use them again. Between the timeline given when we signed the contract to the communication with our consultant to the little details on the final product, I feel there are better companies out there.
Lancaster's management team was excellent in dealing with issues that arose close to the end of the project, but our sales person was nowhere to be found. No one has called to date to ensure everything went smoothly with installation.
Speaking of installers, they are amazing. Very clean and professional.
