Preventive termite treatment for an existing home usually costs $800–$2,500 upfront for a liquid barrier or bait system, plus about $200–$400 a year for monitoring or warranty renewal. Pre-construction soil treatment for a new 2,000 sq. ft. home runs about $1,200–$2,000 (Fixr, HomeGuide and Truly Nolen data, as of October 2026).

Prevention makes the most sense if you live where subterranean termites are common, if a neighbor has had an infestation, or if you're building a new home and can treat the soil before the slab is poured. A preventive barrier or bait system is far cheaper than repairing structural wood damage later.
This guide covers the cost of prevention for new and existing homes, annual plan and bond prices, a typical first-year budget and how to compare offers. If you already have active termites, start with our termite treatment cost guide.

What affects the price
- Pre-construction or existing home. Treating soil before the slab is poured is the cheapest route, often $1,200–$2,000 for a 2,000 sq. ft. home and as little as $200 for small jobs; treating an existing home costs more because crews must trench, drill slabs or install stations around landscaping.
- Treatment type. Liquid barriers cost $4–$14.50 per linear foot ($800–$4,000 for most homes) and protect for several years, while bait systems cost $1,000–$2,500 to install plus $200–$400 a year in monitoring.
- Home size. Exterior prevention is priced by the foundation perimeter, so larger and more irregular footprints cost more. Borate treatment of framing during construction adds a per-square-foot charge.
- Warranty. Keeping protection active costs $100–$400 a year for renewals or monitoring, or $500–$2,000 a year for a bond that covers retreatment (and sometimes repairs) if termites appear.
Ways to save
- If you're building, ask your builder to include soil pretreatment and a transferable warranty; treating before the slab is poured costs much less than treating later.
- Get at least three quotes and compare five-year costs, not just installation: a cheap bait install with high monitoring fees can cost more than a liquid barrier.
- Ask what the renewal covers: retreatment only, or retreatment plus repair of new damage. Repair coverage is worth more in high-risk areas.
- Take advantage of free inspections offered by many companies before committing to a plan.
- Reduce risk for free by keeping mulch, firewood and wood debris away from the foundation and fixing leaks and drainage problems.
How to get an accurate quote
Ask at least three licensed termite companies for an inspection and written proposal. Give each one the same details:
- Whether the home is under construction or existing, and the foundation type (slab, crawl space or basement).
- Square footage and approximate foundation perimeter in linear feet, plus patios, driveways or additions that touch the house.
- Any past termite activity or treatment and existing warranties.
- Ask what is included: product type, inspection frequency, renewal price, whether the warranty transfers to a buyer, and whether it covers repairs or only retreatment.
FAQ
Is termite prevention worth the cost?
In areas with high termite pressure it usually is. Prevention costs $800–$2,500 upfront for most homes, while repairing termite damage typically runs $600–$3,000 and can exceed $6,000, and homeowners insurance rarely covers it.
How long does preventive termite treatment last?
Liquid barriers generally protect for several years, while bait systems work as long as they're monitored and restocked. Annual inspections keep the warranty valid.
What's the difference between a termite bond and a renewal?
A basic renewal ($100–$400 a year) keeps your warranty active and covers retreatment. A bond ($500–$2,000 a year) is a more comprehensive contract that may also pay for repairs of new damage.
