Why Choose Our Building Maintenance Team?
• An almost unheard-of retention rate for our industry. Turnover in commercial cleaning is notoriously high — ours is not. Our people stay, so you get experienced, tenured crews who know your building and your standards, not a rotating cast of day labor.
• Long-running, loyal accounts. Many of our client relationships span decades — the direct result of that consistency and the trust that comes with it.
• An established operation. Nearly 100 employees in our building maintenance and janitorial division alone, with the depth to staff, supervise, and manage facilities of any size.
• Supervised, in-house crews. Our own trained staff, overseen by a dedicated janitorial operations manager, never subcontracted out.
- Fully insured and bonded
• 30+ years in business. Part of the L & A Crystal family of companies, serving Wisconsin since 1995 — three-plus decades of commercial cleaning and facility experience.
• Green methods, materials, and equipment. Sustainable, environmentally responsible products and processes that are safer for your people and your building — and that support your own LEED and sustainability goals.

Quick FAQ
How is this related to L & A Crystal, the flooring company?
We're part of the same family of companies. L & A Crystal has provided commercial flooring and building services since 1995; our building maintenance division brings that same standard to everyday janitorial and facility care. You can hire either service on its own.
Do you only do cleaning, or maintenance work too?
Both. Beyond janitorial and floor care, our division handles painting, acoustical ceilings, ceramic tile, remodeling and restoration, and full interior buildouts — so one accountable team can keep your facility both clean and well maintained.
What makes your crews different?
Retention. Commercial cleaning is an industry defined by turnover, and ours is exceptionally low. Our cleaners are tenured and experienced, which is why so many of our accounts have stayed with us for decades.
Can you clean after hours or on weekends?
Yes. We build the schedule around your operation — nights, early mornings, weekends, or daytime porter coverage.
Do you use green cleaning products?
Yes. We use green methods, materials, and equipment wherever possible to reduce the impact on your staff, your visitors, and your building, and to support your own sustainability and LEED goals.
Are you insured and bonded?
Yes. We are fully insured, and our crews are bonded for your protection.
