Why Ottawa Homeowners Trust Green Thumb For Tree Trimming & Pruning
Pruning is not a job for the cheapest contractor with a chainsaw. Bad cuts invite decay, disease, and weak regrowth — and a careless crew can damage your property. Credentials, insurance, and a track record matter.
ISA Certified & Arboriculture Canada Trained
Our team holds ISA Certified Arborist credentials and completes ongoing training through Arboriculture Canada and ISA continuing education. Proper pruning is a science — we make the right cuts in the right places so your trees heal cleanly and grow stronger.
Species-Specific, Health-First Pruning
We remove dead, diseased, and weak branches, thin crowns to reduce weight, and shape for structure and clearance — tailored to each tree’s species, age, and condition. The goal is healthier, safer, better-looking trees, not just a quick trim.
Zero-Damage Methodology
We use professional rigging and controlled techniques so every branch comes down safely. No limbs crashing onto decks, fences, or roofs. Zero property damage claims in 7+ years. That’s not luck — that’s methodology.
Local Expertise in Ottawa's Climate
We know Ottawa’s tree species, freeze-thaw cycles, and storm seasons. We prune to reduce ice-storm and high-wind risk, and we assess for Emerald Ash Borer, Dutch Elm Disease, and other regional threats while we’re on site.
Owner-Led By A Certified Arborist
Founder and lead ISA-Certified Arborist Riley Sheldrick personally assesses high-risk jobs and is on-site for critical work. You don’t get a salesperson quoting and a stranger doing the cutting — you get the same expert start to finish.
Every Tree Is Different
Tree Trimming & Pruning Services We Handle Across Ottawa & The Surrounding Region
Every tree has different needs depending on its species, age, structure, and location. Our ISA-Certified Arborists assess each one and apply the right technique for healthy, safe, attractive results.
Crown Thinning
Selectively removing branches throughout the canopy to reduce weight and density. This lets more light and air through, eases stress on limbs, and lowers wind resistance during storms.
Crown Raising / Clearance Trimming
Removing low branches to create clearance over walkways, driveways, lawns, rooflines, and sightlines — so you’re not ducking branches or scraping the car.
Deadwooding & Health Pruning
Removing dead, diseased, or weak branches to stop the spread of decay and disease, protect the rest of the tree, and redirect energy into strong, healthy growth.
Structural & Shaping Pruning
Shaping trees for balanced, attractive form and long-term structural strength — especially valuable for younger trees, where early pruning prevents costly problems later.
Hazardous & Storm-Risk Limb Removal
Targeting overhanging, cracked, or storm-damaged branches that threaten your home, vehicles, or power lines. Available 24/7 when a limb becomes an emergency.

Riley Sheldrick
Founder & Lead Arborist ISA Certified Arborist | Arboriculture Canada Trained | 10+ Years Experience

He built Green Thumb around a different standard. He personally assesses every high-risk job and is on-site for all critical work, bringing the same certified expertise to careful pruning that he does to the region’s most demanding removals.

Don’t Wait Until It’s Too Late
Your Trees May Need Trimming or Pruning If…
Overgrown and neglected trees only get more dangerous — and more expensive to fix. Ottawa’s ice storms and high winds turn weak, untrimmed branches into a real risk to your home and family.
01 You see dead, broken, or hanging branches in the canopy
02 Branches are overgrown and encroaching on your roof, walls, or power lines
03 Low limbs block walkways, driveways, or your view
04 The tree looks misshapen, lopsided, or overly dense
05 You notice signs of disease or pest infestation
06 Branches brush against windows or scrape the house in the wind
07 It’s been more than 2–3 years since the tree was last pruned
