 Trustindex verifies that the original source of the review is Google. Luke and Blanca have been amazing to work with.  They were very responsive on the initial quote request and the team went over all of the cleaning needs in detail.  They also provided a quote that was significantly more competitive than the franchise-based options.  Don't waste money paying franchise fees to a corporation for a slick salesman to "teach" your cleaners how to clean your offices.  Go with an established small business like Smith Bros who directly manage their teams and don't have corporate overhead to include in your monthly payment.

 Trustindex verifies that the original source of the review is Google. **Five-Star Service – Worth Every Penny!**

I’ve had my fair share of disappointments when it comes to janitorial services—missed schedules, subpar cleaning, and even disrupted workspaces. I was starting to think that finding a reliable cleaning company just wasn’t possible.

Then came **Smith Bros**, and wow, what a game-changer! While they may not be the cheapest option, I’ve learned the hard way that **you get what you pay for.** Luke and his team are **professional, thorough, and incredibly dependable.** Every scheduled service is completed flawlessly, and my office has never been cleaner.

Thanks to Smith Bros, my team can focus on what they do best instead of worrying about whether the janitorial staff actually did their job. If you’re looking for **a cleaning service that actually delivers on its promises**, look no further. Highly recommend!
Sorry it’s taken so long to write this review!

 Trustindex verifies that the original source of the review is Google. Great experience! Luke was quick to get me a quote after talking through what we needed for our building. The technicians arrived on time and got to work quickly. It's been difficult to find someone who can clean our space properly, but it looks like Smith Bros was the answer. We'll be having them come monthly!

FREQUENTLY ASKED QUESTIONS

Cleaning Questions from San Marcos Businesses

How do I get started with the service?

It starts with a conversation about your facility and what you need. Smith Bros will schedule a free on-site walkthrough to review the areas to be cleaned, discuss service frequency and any specific requirements, and then provide a recommended cleaning plan and estimate. Once everything is agreed upon, we’ll coordinate a start date and service schedule with you.

How much does commercial cleaning cost in San Marcos?

Commercial cleaning pricing depends on factors such as the size and type of facility, cleaning frequency, areas included, and the services required. Smith Bros provides free on-site estimates so you receive pricing based on the actual needs of your facility rather than a one-size-fits-all rate.

How often should my office or facility be cleaned?

Frequency depends on how your facility is used, the number of employees and visitors, and the areas that require regular attention. Some businesses need service several times per week, while others may need a different schedule. Smith Bros can recommend an appropriate frequency after reviewing your facility.

Can you clean our facility outside of business hours?

Cleaning schedules can be arranged around your operating hours to reduce disruption to employees, customers, patients or visitors. We’ll discuss scheduling options during the walkthrough and determine what works best for your facility.

Do I have to sign a long-term cleaning contract?

No. Smith Bros does not require long-term contracts. We believe ongoing business should be earned through consistent service and responsiveness.

Can we combine recurring cleaning with services such as carpet or floor cleaning?

Yes, recurring office or janitorial cleaning can be supplemented with periodic services such as commercial carpet cleaning, tile and grout cleaning, floor stripping and waxing, window cleaning, and pressure washing based on your facility’s needs.

Is Smith Bros insured?

Yes. Our company is fully insured for the commercial cleaning services we provide.

Do you provide the cleaning supplies and equipment?

Smith Bros provides the professional cleaning products and equipment needed to perform the agreed-upon services, so your business doesn’t have to manage cleaning supplies separately.

Can Smith Bros clean multiple facilities or business locations?

Yes, we can coordinate commercial cleaning across multiple facilities, helping businesses maintain consistent service while simplifying communication and scheduling.
