Your Hazard Assessment Experts

Hazard Assessment Services

Due to age or storms, trees become serious safety hazards when they fall near power lines, homes or other buildings. Let Frontier’s Hazard Assessment experience spare you the headaches of losing a beloved tree, the dangers it can create, and extra insurance costs.

Our highly skilled team of arborists, including one with ISA certification and, can assess whether a tree is a Tree Risk Assessment Qualified “TRAQ” (especially an older one) and if it poses significant risk to the surrounding area. And to you.

First we look for major defects or damage that could cause an entire tree, or any part of it, to fall. We also determine the potential risks to bring to the surrounding area, and recommend the best solution to extend your tree’s life. Never attempt to remove a tree yourself.

The Proactive Solution

The most important part of Frontier’s Hazard Assessment program is proactive. Whether the problem is loose or overgrown branches, rotting deadwood, insects, trunk decay, a leaning tree, or sawdust or mushrooms at the base, we consider all factors when evaluating current and/or potential damage.

We especially recommend a Hazard Assessment for larger, more mature trees either yearly or following every bad storm. Our experienced arborists can spot hard-to-detect defects that can cause any tree to fail when you least expect it.

Bear in mind that landowners are responsible for maintaining tree safety — and for anticipating potential problems. Frontier can help you identify potential (and often costly or dangerous) situations, prescribe proper and ongoing tree care, and advise you on preventive maintenance for all trees on your property.

We want to hear about your tree-hazard concerns. Together let’s develop an effective action plan to keep your property safe.
