Professional Exterior Cleaning You Can Count On
What We Do
From windows to roof moss removal, you only need one trusted company.
Driveways, patios, walkways, and hardscapes — blasted clean without damaging the surface underneath.
Low-pressure, chemical-safe washing that lifts dirt, algae, and mildew without harming siding or paint.
A thorough wash that lifts dirt, mildew, and built-up grime from your deck boards and railings.
Hand-brushed scrubbing with a soft-bristle brush that physically lifts moss, lichen, and built-up debris straight off your shingles without damaging them.
Commercial-grade treatment that kills moss on the surface and the spores underneath, slowing regrowth for longer than store-bought sprays.
Clear leaves, needles, and debris that trap moisture and cause premature wear on your roof.
Clogged gutters can cause real damage to your home. We clear them out and check the flow.
Streak-free interior and exterior window cleaning that actually lets the light back in.
Dirty panels lose efficiency. We clean them safely without voiding your manufacturer warranty.
Commercial-grade LED lights rated for 50,000+ hours, custom fit to your roofline. We handle install, takedown, and de-weatherizing — you just enjoy the lights.

About Landmark
Hi, I'm Trey, the owner of Landmark Exterior Services. I believe hiring someone to work on your home should feel simple. You deserve someone who shows up when they say they will, communicates clearly, pays attention to the details, and treats your property with genuine care. That's exactly how I operate every day.
When you hire Landmark, you're trusting me with one of your biggest investments. I don't take that responsibility lightly — I'd rather spend the extra time to do the job right than rush through it just to get to the next appointment.
My goal isn't to become the biggest exterior cleaning company around. My goal is to build the company homeowners recommend because they know they'll receive honest service, exceptional workmanship, and a stress-free experience from beginning to end. I'd be honored to earn your trust and the opportunity to care for your home.
