“A huge dead cottonwood was leaning over our garage. Timberline brought a crane, dropped it piece by piece without touching a thing, and raked the yard cleaner than they found it. Pros.”
Greg T.Boulder
“We needed defensible space done to meet the fire district's requirements. They walked the property, explained the zones, and did exactly what they said — and the quote was fair. Highly recommend.”
Marisol R.Louisville
“A spring storm dropped a limb across our driveway at 10pm. I called, they came that night, cleared it, and came back to grind the stump. Couldn't ask for more.”

Questions, answered
Do you handle tree emergencies?
Yes — we run 24/7 emergency tree service. If a tree is down on your home, car, driveway, or power lines, call (303) 555-0148 and we'll talk through the situation and get a crew out to make it safe.
Are you licensed, insured, and certified?
Yes. Timberline is fully licensed and insured, and our work is led by ISA-certified arborists. We're glad to share credentials and proof of insurance when we give you an estimate.
What does defensible space work involve?
We thin ladder fuels, limb up trees, clear brush, and create the Zone 1–3 spacing that fire districts recommend. We walk the property with you, flag what stays, and follow Colorado and local guidelines.
Is the estimate really free?
Yes. We come out, look at the trees and the access, talk through your options, and give you a clear written estimate at no charge — no pressure to book on the spot.
