Booking

What to send when you book a Wewahitchka test

  • The address

    Where the house is, as it appears on the permit.

  • The permit number

    The number on the building permit for the house, so the test is matched to the right job.

  • The ready date

    The day you expect the shell to be ready. A close estimate is fine, and it can be moved by calling the office.

  • The site contact

    A name and phone number for whoever can let us into the house and answer questions about it on the day.

Worth mentioning

Details that help set up the test

Some features of a house change what sits inside the measured boundary, so mention them when you book.

  • A sealed attic

    If the attic is sealed and insulated at the roof deck, it is opened to the house and measured with it. A vented attic stays outside the test.

  • An attached garage

    An unheated, uncooled garage is outside the test, and the wall and door it shares with the house are part of the boundary.

  • A raised floor

    On a house built over open space, the floor is part of the shell, and every drain, duct and wire through it counts.

  • A bonus room

    A heated and cooled room over the garage or under the roof is inside the test, along with the walls and floor that separate it from attic or garage space.

  • Several houses

    Give the details for each one. Each house is tested on its own and gets its own result.

The limit

The number a Wewahitchka house is measured against

Gulf County is in Climate Zone 2 under Table R301.1 of the Florida Building Code, Energy Conservation. For Climate Zones 1 and 2, section R402.4.1.2 of the 8th Edition (2023) sets the limit for new houses at 7 air changes per hour at 50 pascals.

  • What the reading means

    How many times the full volume of air in the house would leak out and be replaced in an hour, with the house held at 50 pascals.

  • At 7 or under

    The house is within the limit for air leakage.

  • Above 7

    The leaks are corrected and the house is tested again under the same conditions. Call the office when the corrections are finished and a retest date is set.

  • The same across the area

    All nine counties we serve fall in Climate Zone 2, so the limit is the same wherever the house is built.

When to call

Call once you can name the day the last opening through the shell will be made. Booking at that point, rather than at the end of the build, leaves time to spare before you need the result. Paint, flooring, trim, cabinets and countertops do not need to be done first, because they do not change the reading.

Before test day

Openings to look over before the Wewahitchka test

The reading counts every gap in the shell, and a builder can check these before the date.

  • Attic scuttle or stair

    Weatherstripped, and latched so it pulls tight to the ceiling.

  • Top plates

    Openings for wires and pipes into the attic filled.

  • Ceiling fixtures

    Gaps around can lights, bath fan housings and register boots closed.

  • Outside walls

    Gaps around the electric service, hose bibs and the air conditioning lines closed.

  • Air handler closet

    A closet framed around the air handler, with a return built into it, closed off from the attic.

  • Soffits and chases

    A soffit over the kitchen cabinets, or a chase for ducts or a flue, capped where it meets the attic.

  • Fireplace chase

    The framed box around a flue closed off from the attic and the walls.

Crews working during the test

Anyone working inside should stay put or step out before the fan starts, instead of coming and going while it runs, since an opened door changes the reading. Work that needs a door propped open, like carrying in flooring or cabinets, can start again as soon as the test is over.

Owner-builders in Wewahitchka

An owner building a house under their own permit books the test the same way a builder does, with the same details. As the owner, you will be the first to know when your plumber, electrician and air conditioning installer have made their last openings, so that is the date to give us.

Additions and alterations

An addition or alteration that makes up less than 85 percent of the building shell is an exception in the code and is not required to have the test. A project at or above that share is tested like a new house.

Test-day setup in brief

On the day, the windows and exterior doors are shut but not sealed, fireplace and stove doors are closed, and every exhaust, intake and flue damper is closed. Interior doors are open where they are hung, the heating and cooling is off, and the supply and return registers are fully open. A fan is then fitted in an exterior doorway, and it holds the house at the test pressure while the leakage is measured.

    Seamless gutters, formed on site and hung once the roof and fascia are done, scheduled around the builder.

FAQ

Wewahitchka blower door questions

Have another question? Call (850) 819-6031.

Do you test houses outside Gulf County?
Yes. We run blower door tests in Bay, Walton, Jackson, Washington, Holmes, Calhoun, Franklin and Liberty counties as well as Gulf, and every one of those tests is booked through this same office.
Does a bigger house get more room on the limit?
No. Because the reading is figured against the volume of the house, a larger house can let more air through in total and still land on the same number as a smaller one. The limit itself does not change with size.
Is a safe room inside the house part of the test?
Yes. A safe room inside the heated and cooled space is part of the volume being measured, and its door is treated like any other interior door.
Do the exterior doors need their weatherstripping?
Yes. The leakage around each exterior door is part of the reading, so the weatherstripping and the bottom sweep should be on before the test.
Is a porch ceiling part of the test?
No. A porch ceiling is outside the house. Wires that run from a porch light back into the wall or attic pass through the shell, and those openings count.
Does a storm shelter outside the house count?
No. A shelter set in the yard or in the garage floor is outside the house shell and plays no part in the reading.
