The issues we fix most for San Bernardino homeowners, and why they happen here.
Why it happens: San Bernardino County's seasonal winter rainfall leaves soil moist around foundations, creating termites a ideal highway into the home. Mild warm, dry summers speeds up their tunneling.
Our approach: We find every mud tube and trace it back to the colony. Then we apply a precision liquid barrier to eliminate the entry point.
Why it happens: San Bernardino's damp mild, wet winters allows moisture to build up in crawl spaces, drawing subterranean termites. Wood remains wet and turns easy targets.
Our approach: We check the subfloor and pinpoint affected wood. After that, we use a wood treatment and suggest moisture control fixes to prevent recurring problems.
Why it happens: After spring rains, ground termites fly to launch new colonies. San Bernardino's warm warm, dry summers triggers these swarms, and they often wind up in homes.
Our approach: We verify the type and locate the source colony. Then we apply a colony elimination that stops the infestation and prevents future swarms.
Why it happens: Termites consume wood from the interior, leaving a thin layer that looks fine. San Bernardino homes with slab problems are especially at risk.
Our approach: We use moisture meters and thermal imaging to find the damage. Then we repair the colony and advise on structural repairs.
