01

Insurance & Liability

Is Greenlight Services licensed and insured?

We maintain workers compensation, liability, and umbrella insurances — COAs available upon request. Our crews are trained to do their job safely, being careful on your property, and take proper precautions around your employees and customers. The "neighborhood guy" doesn't have these protections, exposing you to unnecessary risk.

02

Experience & Track Record

How long has Greenlight been in business?

Hi, my name is Woody French. I started this window cleaning business on October 1st, 1994. Hard to believe I've been doing this for over 30 years. We now have a justly deserved reputation of high quality service across Houston, Fort Bend, and Montgomery counties. That longevity isn’t just a number — it’s a record of consistent, professional results.

03

Local References

Do you have referrals in my local area?

Absolutely. We have a large, loyal client base across Harris, Montgomery, and Fort Bend counties. We’re happy to provide specific references from someone near you upon request — all you have to do is ask. 🙂

04

Employee Safety

Do you have an ongoing safety program?

Yes, and we go beyond what Texas law requires. Our team is continuously trained in current safety protocols. We invest in proper equipment, instructions, and procedures so every job is completed without incident — our 30 year streak of safety isn't just a stroke of luck

05

Background Checks

Do employees undergo background checks and drug testing?

Every Greenlight employee passes a criminal background check and drug screen before they’re offered a position. When our team arrives at your property, you can have complete confidence in who you’re working with.

06

Scheduling Flexibility

How flexible is your scheduling?

Very. We build window cleaning schedules around your needs — not the other way around. Whether you need weekly, every two weeks, every four weeks, monthly, or seasonal service, we’ll create a maintenance plan that fits your property, your budget, and your calendar.

07

Reputation & Reviews

Do you have good reviews?

Yes — and many long-term loyal customers. We’ve been earning 5-star reviews across The Galleria, River Oaks, Memorial, Midtown, and The Heights for over 30 years. We’re proud to share our Google and Yelp profiles with anyone who wants to verify our track record.
