Mature trees with structural weaknesses do not always need to come down. Tree cabling and bracing systems provide supplemental support that reduces the risk of branch or stem failure while preserving the tree's shade, beauty, and property value. Our arborists install systems following ANSI A300 standards using both static and dynamic hardware.
Longmont's exposure to Chinook winds and heavy wet snow creates significant mechanical stress on trees with codominant stems, heavy lateral limbs, and previous storm damage. Cabling and bracing can extend the safe, functional life of these trees by decades when properly installed and maintained. Our assessment determines exactly what support system your tree needs.

Steel cable systems provide rigid support for codominant stems and heavy lateral branches that are at risk of failure. We install cables at the proper height and tension to limit dangerous movement while allowing natural growth.
Synthetic dynamic systems allow controlled tree movement that encourages natural strengthening of wood fiber over time. These systems are ideal for trees that need support but benefit from maintaining some flexibility during wind events.
Before installing any hardware, our arborists perform a thorough structural assessment including visual inspection, lean measurement, and evaluation of branch attachment strength. This determines whether cabling, bracing, or removal is the right approach.

Frequently Asked Questions
Tree Service can be complex, and weโre here to provide answers to common questions. Here are some frequently asked questions from our clients.
Tree trimming costs in Longmont typically range from $200 to $1,800 depending on the tree species, height, number of branches requiring work, and accessibility. Cottonwoods and mature elms along the St. Vrain corridor often fall on the higher end due to their size. We provide free on-site estimates so you know exactly what to expect before any work begins.
Longmont requires all tree contractors performing work aloft to hold a City of Longmont Tree Contractor License under Municipal Code Chapter 6.88. Licensed contractors must carry $1,000,000 in general liability insurance and employ at least one ISA Certified Arborist. Always ask for proof of licensing before hiring anyone to work on your trees.
The best time to trim most trees in Longmont is during late fall through early spring while they are dormant. This reduces stress on the tree and minimizes disease transmission risk. However, dead or hazardous branches should be removed immediately regardless of season. Spring-flowering trees like crabapples are best pruned right after they bloom.
Signs your tree may need removal include large dead branches in the crown, significant trunk decay or cavities, visible fungal growth at the base, severe lean that has changed recently, root heaving, and major structural cracks. If more than 50 percent of the crown is dead or damaged, removal is usually more practical than attempting to save the tree.
Emerald ash borer was confirmed in Longmont in 2016 and now threatens every ash tree in the city. Treatment with trunk injection is most effective when started before significant canopy loss occurs. The City of Longmont Forestry Services maintains a public ash tree map and encourages private property owners to consult with a licensed tree contractor about treatment options.
After the 2021 Marshall Fire destroyed over 1,100 homes in Boulder County, wildfire mitigation became essential for properties near the foothills. Creating defensible space involves thinning trees, removing ladder fuels, and maintaining clearance zones around structures. Boulder County homeowners may qualify for 50 percent cost sharing through the Wildfire Partners program.
Trees with codominant stems, V-shaped crotches with included bark, long heavy lateral limbs, or previous storm damage are common candidates for cabling or bracing. In Longmont, mature cottonwoods and silver maples frequently develop structural weaknesses that benefit from supplemental support rather than removal, preserving their shade and property value.
Modern steel cable systems typically last 10 to 15 years before requiring inspection and potential replacement. Dynamic cabling systems using synthetic materials may have shorter lifespans but allow more natural tree movement. We inspect all installed systems on a recommended schedule and adjust or replace hardware as the tree grows and conditions change.
When a tree is otherwise healthy and structurally sound except for a specific weakness, cabling is often the better choice. Mature trees provide significant property value, energy savings through shade, and environmental benefits that take decades to replace. Our arborists evaluate whether the structural issue can be effectively addressed through cabling or whether removal is the safer long-term option.
Properly installed cabling systems cause minimal impact to the tree. Modern hardware is designed to be installed without excessive drilling, and trees naturally grow around the attachment points. Following ANSI A300 standards for installation ensures the system supports the tree without restricting healthy growth or creating new stress points in the wood.

They removed a massive dead cottonwood that was leaning toward our garage after the spring snowstorm. The crew was professional, careful with our landscaping, and cleaned everything up perfectly. Best tree service experience we have had in Longmont.

We hired them to treat our two large ash trees for emerald ash borer. They explained the treatment process clearly, answered all our questions, and followed up to check on the trees afterward. Very knowledgeable and honest about what our trees actually needed.
โ Boulder County Resident

Called for emergency service after a wind event dropped a huge branch across our driveway. They responded the same day and had everything cleared within a couple hours. Fair price, great crew, and they even gave us recommendations for preventing future issues.
