Andy Sehremelis on Customer Experience at the Express Car Wash

By Andy Sehremelis · October 30, 2026

Andy Sehremelis has built, owned and operated express car washes in Southern California, drawing on his background as the founder of Parkcrest Construction in Chino. The express car wash format is largely automated, yet customers judge it on a series of small experiences from the moment they turn into the property until they drive away.

Andy Sehremelis on the First Impression

Customers form an opinion before they reach the pay station. Clear signage, a clean entrance, well-maintained landscaping and visible wash menus tell drivers that the property is cared for. A confusing entrance or a cluttered property creates doubt about the quality of the wash itself.

Directional signage should make it obvious where to go for a single wash, where members enter and where vacuums are located.

Andy Sehremelis on the Pay Station

The pay station is the main point of decision. Menus should be easy to read from the driver's seat, with a limited number of clearly differentiated wash levels. Payment should be quick and reliable, and attendants should be nearby to help customers who have questions or are new to the format.

Membership customers value fast, simple entry. Lanes or recognition systems dedicated to members reduce waiting and reinforce the value of the membership.

Andy Sehremelis on Guiding Vehicles Into the Tunnel

Entering a conveyor tunnel can be unfamiliar for some drivers. Attendants who give clear, calm instructions and signage that explains each step reduce anxiety and protect both vehicles and equipment. Consistent loading procedures also keep the line moving.

Safety is part of the customer experience. Well-trained attendants watch for vehicle types or accessories that may not be suitable for the tunnel and explain the reason politely.

Andy Sehremelis on Wash Quality

The result of the wash is the core of the service. Clean, dry vehicles depend on properly maintained brushes, correctly calibrated chemicals and effective dryers. Regular inspections of finished vehicles at the tunnel exit help catch problems early.

When a customer is not satisfied, a quick and respectful response, such as a rewash, often turns a complaint into continued loyalty.

Andy Sehremelis on the Vacuum Area

Many express car wash customers spend as much time in the vacuum area as in the tunnel. Strong suction, clean nozzles, shade where possible, trash receptacles and adequate lighting make the area comfortable and useful. Layout should allow vehicles to enter and leave vacuum spaces without blocking traffic leaving the tunnel.

Keeping this area clean throughout the day is one of the most visible signals of good management.

Andy Sehremelis on Property Design and Traffic Flow

Much of the customer experience is determined when the property is designed. Adequate queuing space keeps waiting vehicles off public streets. Clear separation between the pay lanes, the tunnel exit and the vacuum area prevents conflicts between vehicles. Lighting, landscaping and building materials influence how safe and inviting the property feels.

Builders who understand express car wash operations can anticipate these needs during design, which is far less expensive than correcting them after opening. Parkcrest Construction's experience with commercial building informs this kind of planning.

Andy Sehremelis on Staff Training and Service

Attendants are the face of an express car wash. They greet customers, explain wash options and memberships, guide vehicles into the tunnel and keep the property clean. Training should cover equipment safety, customer communication, membership procedures and how to respond to complaints.

A courteous attendant who resolves a problem quickly can leave a stronger impression than the wash itself. Recognizing staff who deliver that level of service reinforces the standard for the entire team and supports a consistent experience on every visit.

Andy Sehremelis on Memberships and Ongoing Service

Memberships create an ongoing relationship with customers. Clear terms, simple account changes and responsive customer service build trust. Members notice consistency, and they are the customers most likely to recommend a wash to others.

From a builder's and operator's perspective, the best customer experience at an express car wash comes from combining sound site design with dependable equipment and attentive staff. Each element supports the others, and customers feel the difference on every visit.

Customer experience at an express car wash is the sum of many details, from the first sign at the entrance to the last pass of the vacuum. Owners who pay attention to each of those details, and who revisit them regularly as customer expectations change, build the loyalty that sustains the business.
