FAQs
What does a termite inspection cost?
The inspection fee depends on location, size of home, and timing, such as rushed real estate reports. Inspection fees can be waived at the discretion of the inspector depending on the situation. Call with additional details for a quote.
How long is your warranty?
Residential structures receive a three year warranty for any full structure treatment. For other warranties, including localized treatment and ongoing programs, call for complete warranty details.
What is your service area?
The South Bay, the Peninsula, and the East Bay up to San Leandro. San Francisco was added in 2024 due to client demand. Termite control and management services are listed for Alameda, San Francisco, San Mateo, and Santa Clara counties.
How long does an inspection or treatment take?
Inspections vary with accessibility, and most homes take around 2 to 3 hours. Fumigations take as little as 3 days or as long as 6 days depending on schedule and target organism. Soil treatments and localized treatments are usually completed within the same day.
How do I pay for service?
Check or online bank transfer is preferred. Major credit cards are also accepted, including Visa, Mastercard, and American Express.
What types of inspections do you offer?
A full inspection covers all accessible areas, including interior, exterior, subarea, crawlspace, and garage. A supplemental inspection adds anything on top of the original inspection, and detached structures can be added on request. A limited inspection covers only certain areas the customer asks about. A reinspection can be scheduled within the first 4 months to update deficiencies.
How long is a fumigation effective for?
Fumigation kills drywood termites throughout the structure but cannot prevent reinfestation. The average life cycle for a fumigation is between 10 and 12 years. Proper maintenance can help delay termite progress in the home.
