I cannot say enough good things about Craig and the crew at Hartwick Tree & Wood. From the initial estimate to the final rake-up, they were top-notch professionals every step of the way. ​Watching this crew work is truly impressive—they operate like a well-oiled machine with total precision and a clear focus on safety. They handled the job efficiently, took great care around our property, and when they were finished, the yard was cleaner than when they arrived. It’s rare to find contractors who communicate clearly, show up on time, and take this much pride in their work. ​If you need tree removal, trimming, or stump grinding done right in the area, don't look anywhere else. Highly, highly recommend Craig and Hartwick Tree & Wood!

I can’t recommend Hartwick Arborist enough. Craig and his team did an incredible job removing a large tree from my property. From start to finish, they were professional, efficient, knowledgeable, and highly skilled. Watching the team work was honestly impressive. They were well organized, communicated clearly, and handled every step with precision and care. What I expected to be a full-day project was completed by noon without ever feeling rushed. Their preparation, attention to safety, and teamwork really stood out. The cleanup was just as impressive as the tree removal itself—they left the property looking spotless. It’s clear that Craig and his crew genuinely care about the quality of their work and their customers. If you’re looking for certified arborists who go above and beyond, I wouldn’t hesitate to recommend Hartwick Arborist. They’ve absolutely earned a 5-star review from me. Thank you again, Craig and the team!

Craig from Hartwick Tree and Wood Ltd. did a fabulous job on cutting down a tree at the front of my house. Communication with him was excellent & he was very reliable. Him & a partner had cut a large tree down & had the place cleaned up in only an hour. We had a family emergency so I almost cancelled my tree cutting, but Craig said there's no need to canceI. He was able to handle everything even though I wasn't home. I would use him again in a heart Great job!

What Mature Trees Along Merritt Street and Port Dalhousie Are Actually Telling You

St. Catharines Trees Have a History

The residential streets of Port Dalhousie and the Merritt Street corridor are lined with some of the oldest urban tree canopies in the Niagara Region. And if you live near either, you already know that tree service in the area looks nothing like a simple trim-and-go job. These trees have decades of growth behind them, and with that comes structural complexity that isn’t visible from the curb.

A large limb that looks solid from below can be hollowing out from the inside. Root systems that once anchored quietly beneath a lawn can start pushing into foundations, driveways, and underground lines. Disease pressure in the Niagara Region moves fast, and by the time you notice something is off, the problem has usually been developing for years.

If you’ve spotted a lean after a storm, noticed unusual bark patterns, or received a city notice about a tree on your lot, an ISA Certified Arborist can tell you exactly what you’re dealing with. Professional tree care service starts with an honest assessment, not assumptions.

How Delayed Action Can Turn a Manageable Job Into an Emergency

A Leaning Tree Doesn’t Wait For A Convenient Time To Fall

A large tree leaning toward your house after a Niagara Region storm is not a problem you can schedule around. The longer it stays, the more the root system shifts, the weaker the structural integrity becomes, and your exposure to liability grows by the day.

If you’ve received a city notice about a tree on your lot, that clock is already running. Ignoring it doesn’t make the safety risk smaller. It makes the eventual cost larger. Emergency tree service rates in St. Catharines can be much higher than what routine tree removal would cost under normal circumstances.

Uncertain whether it’s the tree’s health or storm damage causing the lean? That’s exactly when you need a certified assessment, not a guess. Safety concerns that go unchecked have a way of turning a straightforward removal into a full emergency service call at the worst possible hour.

What An ISA Certified Arborist Does

ISA Certified Arborist status is not a marketing badge. Earning it requires documented training, a rigorous examination, and ongoing continuing education tied to current arboricultural standards. That credential changes what happens when a tree care professional walks onto your property.

A certified arborist identifies tree species accurately, reads the signs of disease or structural failure that an untrained eye misses entirely, and evaluates risk in a way that holds up in writing.

If your insurer needs documentation after storm damage, or the city has flagged a tree on your lot and requires a formal submission, professional arborists can produce written arborist reports that satisfy those requirements. A general crew cannot do that.

If you have a mature tree near Twelve Mile Creek or in an established St. Catharines neighbourhood, and you are not sure whether it is declining or simply stressed, that distinction matters. The wrong call costs you a tree you didn’t need to lose or keeps a hazard standing longer than it should.

From Stump Grinding to Plant Health Care: What Complete Tree Service Looks Like

Most Tree Companies Stop At Removal - We Don’t

A removal-only approach treats every tree problem the same way: cut it down and move on. That works sometimes. But near the water, where mature riparian trees have established root systems tied to unstable banks, removal without a health assessment can cause more problems than it solves. Some of those trees just need treatment, not a chainsaw.

There’s a real difference between a company chasing volume and a family-owned Niagara tree service that actually wants your property to be better off after we leave. Tree trimming, deep root fertilization, plant health care, lot clearing, and stump removal. These aren’t upsells. They’re what complete tree care actually looks like.

If you’ve got a tree stump sitting in your yard after another crew left, or a new tree you want to establish properly, or overgrowth that’s overdue for routine maintenance, that’s exactly the work we do. You shouldn’t have to call three different companies to handle one property.

You’ve been watching that tree for a while now. Telling yourself you’ll deal with it after the weekend, after the month gets less busy. Meanwhile, the window for lower-intervention options quietly narrows. Once a tree reaches a certain point of decline, removal is often the only path left.

There’s another piece most people miss: documented risk changes how insurers respond to a claim. If a tree falls and there’s no record of a professional assessment, that conversation gets harder fast. Waiting doesn’t just cost you money. It can cost you coverage.

If you manage commercial properties or a strata, the calculus is the same. The city’s compliance timeline doesn’t pause while you’re weighing your options.

Call now for your free quote. As a tree company serving St. Catharines and the broader Niagara Peninsula, including Niagara-on-the-Lake and Niagara Falls, we bring an ISA Certified Arborist to every job. You get a real assessment, not a sales pitch.
