The 2021 Marshall Fire changed everything for Boulder County property owners. Creating defensible space around your home is no longer optional for properties in or near the wildland-urban interface. Our fire mitigation team works with homeowners, the Wildfire Partners program, and local fire departments to reduce wildfire risk through strategic tree thinning and vegetation management.
Boulder County building code now requires defensible space for new construction in both Wildfire Zone 1 and Zone 2. Even existing homes benefit from professional mitigation that reduces fuel loads and creates spacing between tree crowns. Our crew follows Colorado State Forest Service guidelines and can work directly from Wildfire Partners assessment reports for qualifying properties.

We establish and maintain the three defensible space zones recommended by the Colorado State Forest Service. This includes creating a noncombustible perimeter near structures, thinning trees in the intermediate zone, and reducing fuel density in the extended zone.
Dense conifer stands near homes create continuous fuel pathways for wildfire. We thin trees to create crown spacing, remove ladder fuels like low branches and brush, and clear dead material that accelerates fire spread across your property.
We work directly with Boulder County's Wildfire Partners program, implementing the specific recommendations from your property assessment. Qualifying homeowners receive up to 50 percent cost sharing for mitigation work through this program.

While our home base is Longmont, our tree care crews serve communities throughout Boulder County and the northern Front Range. From the established neighborhoods of Boulder and Lafayette to the growing communities of Erie and Berthoud, we bring the same licensed, insured, and ISA-certified expertise to every property we work on. The tree species, soil conditions, and climate challenges across these communities are similar to what we see daily in Longmont, which means our local knowledge translates directly to quality results wherever we work.
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.
Defensible space is a buffer zone around your home where vegetation has been managed to reduce wildfire fuel. Properties in western Boulder County and near the foothills are required to create defensible space under county building code. Even properties within Longmont city limits benefit from fire-conscious landscaping given the proximity to foothill fire corridors.
Wildfire Partners is a Boulder County program that provides homeowners with a comprehensive property assessment and up to 50 percent cost sharing for mitigation work, capped at $2,000. The program covers tree thinning, brush removal, and other vegetation management needed to create defensible space. Our crew is experienced with Wildfire Partners specifications and can work directly from their assessment reports.
Fire mitigation costs vary widely based on property size, tree density, slope, and the extent of thinning required. Small residential projects may start around $1,500 while heavily forested foothill properties can run $10,000 or more. The Wildfire Partners cost-sharing program can offset up to half the expense for qualifying Boulder County properties.
Fire mitigation focuses on creating spacing between tree crowns, removing ladder fuels like low branches and brush, and thinning dense conifer stands. We prioritize removing dead or stressed trees, small diameter conifers growing in dense clusters, and any trees within the noncombustible perimeter zone closest to structures. Healthy mature trees are preserved wherever possible.

โ Longmont Homeowner

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.
