Checklist before the test may begin:

To achieve a fair test result, the building envelope must be complete. This includes external doors, all glazing plus frames sealed and cladding completed.

Any forms of loft hatches should be finished and ideally have a draft excluder.

All light fixtures and socket fixtures to be fitted.

Window frames to be sealed between the external walls, i.e, silicone/expanding foam.

SVP pipes or any types of pipes exiting the envelope area should be well sealed.

All plumbing is installed, and all traps/U bends have water in them.

Skirting boards to be fixed and sealed.

Also noted that chimneys should be checked before we arrive on site to make sure they are properly sealed and that any flues that have been installed are not leaking.

Please be aware that testing cannot take place in high wind conditions.

Upon our visit, we will temporarily seal extractor fans and possibly trickle vents depending on when the dwelling was constructed.

It should be noted that to do the test we will require 240v or 110v power , if this is a problem please contact us before our visit.
