The issues we fix most for Rancho Cucamonga homeowners, and why they happen here.
Why it happens: San Bernardino County's seasonal winter rainfall leaves soil damp around foundations, giving termites a ideal path into the home. Mild warm, dry summers accelerates their movement.
Our approach: We find every shelter tube and trace it back to the nest. Then we treat a targeted liquid barrier to cut off the access point.
Why it happens: Rancho Cucamonga's humid mild, wet winters allows moisture to accumulate in crawl spaces, drawing subterranean termites. Wood remains wet and becomes vulnerable targets.
Our approach: We inspect the subfloor and pinpoint affected wood. After that, we apply a wood treatment and recommend ventilation fixes to prevent recurring problems.
Why it happens: After winter rains, ground termites swarm to start new colonies. Rancho Cucamonga's mild warm, dry summers triggers these flights, and they frequently end up in homes.
Our approach: We verify the type and locate the source colony. Then we use a colony elimination that stops the cycle and prevents future swarms.
Why it happens: Termites consume wood from the inside out, leaving a thin veneer that looks fine. Rancho Cucamonga homes with slab problems are particularly vulnerable.
Our approach: We employ sounding tools and thermal imaging to map the infestation. Then we treat the colony and advise on wood repairs.
