Removing trees near homes, fences, or utilities demands expertise. Our team uses crane-assisted takedowns and sectional cutting to safely eliminate hazardous, dead, or overgrown trees. Common removal triggers in O’Fallon include:
We protect lawns with plywood mats and control debris with ropes and rigging. After removal, we can grind stumps below grade and restore soil for new plantings.
Regular pruning keeps trees strong and attractive. Our arborists remove deadwood, thin dense canopies, and shape branches to improve airflow and sunlight penetration. This prevents storm breakage, reduces pest habitats, and enhances landscape beauty. In the St. Louis region, certain species face unique challenges:
Proper timing and technique are critical. We tailor pruning plans to each tree’s species, age, and condition.

When high winds or ice bring down branches, Gildersleeve Tree Service responds fast. Our emergency crews arrive with chainsaws, chippers, and hauling equipment to clear:
We secure sites, remove debris, and restore access—any hour, any day.
Leftover stumps attract termites, sprout suckers, and hinder mowing. We use high-powered grinders to pulverize stumps and roots 8–12 inches below ground. The area is then backfilled with topsoil and seeded for a smooth lawn finish. This eliminates tripping hazards and prepares space for new landscaping or construction.
Tree Health Challenges in the St. Louis Metro East region’s clay soil, humid summers, and harsh winters stress local trees. Beyond oak wilt and EAB, watch for:
Early intervention—deep-root fertilization, soil aeration, or cabling—preserves mature trees and prevents costly removals.
We deploy bucket trucks for elevated work, mini excavators for debris handling, and rope systems for controlled drops in confined spaces. All operations follow industry safety protocols to protect your property and our crew.
