Free assessment
We count the vents, check current conditions, and identify where energy loss is happening.
Certified local installer
Seal the vents that quietly leak heated and cooled air all year long.
Thermo-Trap© seals exhaust and intake vents to help block birds and rodents, reduce winter heat loss, and keep cooled air inside the home in summer. In a typical 3,000 sq. ft. home in Ottawa, four traps are estimated to reduce annual energy costs by about $440.
On-site installation
A local install team, not a distant distributor.
Purple Property Services installs Thermo-Trap© locally across Ottawa-area neighbourhoods, with real on-site assessments and professional installation.
Why people install it now
Avoid the $250 - $500 exterminator call for a single vent problem.
Thermo-Trap© helps prevent birds, rodents, and other pests from getting into vents in the first place. It is a cleaner long-term fix than waiting for a problem that usually costs more under pressure.
