When drywood termite damage is spread across multiple wall sections or floors, spot treatment can't reach every colony — tent fumigation with sulfuryl fluoride is what clears the entire structure at once. Because the gas penetrates solid wood rather than just surface cracks, fumigation reaches colonies living deep inside framing that no injection or spray treatment could ever access.
We inspect the extent of damage first, since fumigation is only recommended when localized treatment genuinely won't reach every colony.


Structural fumigation legally requires specialized certification, which our lead fumigators carry and maintain.
We coordinate tenting, gas exposure time, and aeration clearance into a clear timeline so you know exactly when you can re-enter.
You'll see one written quote covering tenting, gas application, aeration, and clearance testing.
We use sulfuryl fluoride gas with certified monitoring equipment to confirm safe concentration and clearance levels.
The entire structure is sealed under tarpaulin and treated with fumigant gas that penetrates every wall void and framing member.
When drywood termite colonies are spread across multiple areas of a structure, fumigation eliminates all of them in one treatment.
Our team walks you through exactly what needs to leave the structure and what can safely stay sealed inside.
After gas exposure, the structure is aerated and tested with certified equipment before we clear it safe for re-entry.
Larger commercial buildings and multi-unit structures get coordinated tenting plans accounting for tenant notification and timing.
You'll receive full documentation of the fumigation, including gas application records and clearance certification.

Our fumigation lead arrives to walk the property and explain the process before any commitment is made.
Assessment includes a clear timeline for tenting, gas exposure, aeration, and when you can safely return.
The structure is tented, treated, aerated, and clearance-tested before we certify it safe for re-entry.
Knowing exactly when we could move back in made planning around the fumigation so much less stressful.
The clearance documentation they provided was exactly what our insurance company needed on file.
Appreciated that they didn't just upsell us into tenting when a smaller treatment would have worked.
Buying an older home with visible drywood damage in three separate rooms, fumigation ended up being the only option that made sense, and the crew explained every stage of tenting clearly.

Inspection findings, not a sales pitch, determine whether tenting is the right call for your structure.
We'll give you a specific timeline based on your structure size once the assessment is complete.
Most furniture and belongings can stay sealed inside; it's primarily consumables and living things that need to be removed.
Yes — clearance testing with certified equipment confirms gas levels are safe before we allow anyone back inside.
Compliance paperwork covering the entire process is available whenever you need it on file.
Yes, we coordinate larger tenting projects including tenant notification and scheduling for multi-unit structures.
