Most calls start with a question, not a job: the post oak dropped half its leaves in August, the pine by the driveway has a new lean, a builder trenched through the roots last spring. A tree health check answers that question first. Someone walks the tree from the root flare to the crown, looks for decay, cracks, dead limbs and disease, and writes down whether the tree needs pruning, treatment, watching or removal.
The point is to spend money on the right thing. A tree that can be saved with deadwood removal and water should not be taken down, and a tree with a hollow base over a bedroom should not be trimmed and left standing.

What goes wrong with East Texas trees
Drought is the root of most of it. After a dry summer, the oaks around Tyler are open to hypoxylon canker, a fungus that the Texas A&M Forest Service lists among the biggest threats to weakened hardwoods in East Texas. It shows up as browning leaves and bark peeling away to expose a gray, brown or black crust on the trunk or a big limb, and it can attack any oak: post, red, water, white and live oaks alike. There is no cure; the only defense is keeping the tree vigorous, which in a dry year means deep watering where a hose can reach.
Construction is the other common cause. A driveway poured over the roots, a trench for a sewer line, or a foot of fill dirt spread for a new pad can kill a mature oak slowly over two or three years, and the decline is often blamed on something else. A check before the work starts can mark where the roots are and what they can lose.
Credentials are worth asking about. The International Society of Arboriculture certifies arborists, and its public directory at treesaregood.org lets you look someone up and confirm the credential is current; not every certified arborist is listed, so ask for the number too. Any honest crew will tell you whether the person looking at your tree holds one.
Arborist Services: Tree Health and Risk Checks pricing in Tyler
A tree health visit on a residential lot is typically priced as a flat call-out, often in the $100 to $250 range around Tyler, for one to several trees on the same property. A written risk report for an insurer, a buyer or a homeowners' association takes longer and costs more.
When the check turns into work, the pruning or removal is quoted on its own, at the same prices as the trimming and removal pages, so the visit does not lock you into anything.

Arborist Services: Tree Health and Risk Checks questions, answered
Can a tree with hypoxylon canker be saved?
Usually not once the crust is visible on the trunk: by then the sapwood is infected and the tree is declining. The Texas A&M Forest Service lists no control beyond keeping trees vigorous, so the work is prevention, watering oaks through drought and avoiding root damage. An infected tree near a house, a drive or a play area should be looked at for removal before it drops limbs.
How do I know if a tree is dangerous to my house?
Warning signs are a new or growing lean, cracks in the trunk or where big limbs join, mushrooms or fungus at the base, bark falling off in sheets, dead limbs over the roof, and soil heaving on one side of the root plate. Any one of them is a reason to have the tree checked; two together usually mean it should come down.
What is the difference between an arborist and a tree service?
An arborist is someone trained in tree biology and care, and certification by the International Society of Arboriculture is the common credential. A tree service is a business that cuts, trims and removes trees, and it may or may not employ a certified arborist. For a health question, ask who will look at the tree and whether they hold the credential.
