Professional, Experienced Janitorial Services

When it comes to keeping your office or industrial space looking its best, you need a janitorial team that understands your space and your needs. Unfortunately, all too many companies are only concerned with adding new contracts to their roster while providing just “good enough” services to keep their business. At Windsor Building Services, we’ve been providing professional, reliable janitorial services in The Woodlands, Conroe, Willis, and other parts of Greater Houston for nearly 30 years. Regardless of the type or size of a client's space, we’re proud to offer options to suit any budget or need.

Janitorial Cleaning Services

And no matter the space, we always have the same goal: systematize the cleaning of your facility so that you can concentrate on the day-to-day operation of your business. To accomplish this, our experienced staff uses the latest, high-quality equipment to guarantee a safe, efficient, clean workspace for you and your employees. Make the right impression every single time with a spotless, healthy facility. Windsor Building Services isn’t the premier janitorial provider in Greater Houston because we have the flashiest ads or most impressive vehicles, but because we don’t believe the job is done until it’s done right.

This allows us to fully customize your services to your needs, budget, and schedule. After all, you shouldn't have to micromanage the cleaning process. It’s our goal to operate as independently from you as possible so that you can focus on what you do best: running your business.
