Critters Talk + before/after photos

• ✓No partial jobs There's no bronze, gold, platinum with critters. It's right or it's wrong, and we only put our name on right.
• ✓The common ask "Just fix where they nested, most of the insulation's still good." Pest companies push this too — it protects their monthly subscription with you.
• ✓Why patching fails Even after every critter's trapped and gone, the urine, droppings, hair, pheromones, and nests are still up there.
• ✓The smell brings more Those pheromones pull new critters in from outside. They'll chew through a two-by-four just to investigate it. Patching a few spots starts a never-ending cycle.
• ✓The right way Strip to bare structure, disinfect, scrub, fog. New plastic and insulation, heavy screen bolted into the foundation with concrete anchors, final fog to kill leftover odor.
• ✓The payoff No smell, no food source, nothing to attract them. A critter passing by has no reason to come in.
• ✓Close "It's your home and your call. We just won't put our name on a critter job that isn't done right."

Blower Door Test Live prop: manometer + hose + pan

• ✓What it is A frame with a big fan goes in your front door; a gauge (the manometer) measures how fast air is leaving the house relative to its size.
• ✓Before / during / after We get a number before, during, and after — so you watch the leak shrink in real time.
• ✓The metric: ACH Air changes per hour. New code is about 2. Plenty of homes come in around 10.
• ✓Why 10 is brutal At 10, all the conditioned air in your house leaks out and has to be replaced ten times an hour. That's why the AC or heat pump feels like it never shuts off — it's chasing air that keeps escaping.
• ✓Pan testing = the powerful part After the whole-house number, we go room to room with a single-channel gauge and a hose under each closed door. Every room gets its own number; the outliers point to the problems.
• ✓Down to the fixture Then a pan over individual spots — light switches, outlets, can lights. A single double light switch can read as wide open to the outside.
• ✓Trace it to the attic That switch traces to an open wall cavity running up to your attic. The top of the wall framing is basically a chimney from the switch straight outside.
• ✓The part people don't realize The insulation on top of that cavity is filthy — it's been an air filter for years. Every door opening and HVAC cycle pulls dust, mold, fiberglass, even critter debris through that switch into the air you breathe.
• ✓The fix Seal the top of the wall and the switch itself, and that pathway is just gone.
• ✓Why we test the whole time Air seal without testing and you miss hidden spots. Once most holes are closed, the leftover moisture and air concentrates through the one spot you missed — like a pressure washer on that point. That causes mold and rot faster than the leaky house would have.
• ✓What you get A full report: before-and-after whole-house numbers, every room's result, all the pan data. On the job our techs seal while I re-test live — if dust kept a spot from sealing, we sweep it, re-seal, watch the number go perfect.

Pressure Balancing Live prop: card tool + manometer

• ✓Everyone skips it Insulation companies skip it entirely. HVAC only touches it on a brand-new system, and plenty don't at all. The few who diagnose it usually don't fix it.
• ✓Balanced vs not Doors open, HVAC running: vents push air in, the return pulls it back. Balanced.
• ✓Close one door Now the only way that air gets back is the gap under the door. Too small a gap and the room goes positive pressure, the hallway goes negative.
• ✓Why it matters at night You're breathing out a lot of moisture while you sleep. In a positive-pressure room that moisture can't get back to the system to be dried.
• ✓Where the moisture goes It's driven through the drywall into the wall cavity. Over time it reaches the sheathing, sometimes the back of your exterior paint — that's the bubbling and peeling nobody can explain.
• ✓Health side It also concentrates dust and allergens in that room, which can make asthma and breathing worse.
• ✓Causes Home layout, multi-story designs, duct sizing, furniture over a vent, doors cut too high off the floor, or a return added wrong.
• ✓How we test Whole house doors open, then doors closed, then each room one at a time. We measure the actual gap under each door with a card tool.
• ✓The fixes Undercut the door for a bigger gap · a jumper duct (insulated pipe through the ceiling connecting two rooms with grills so pressure equalizes) · or an ERV to actively balance the house. If it's a duct or bad-return problem, we point you to the HVAC fix.
• ✓Real example A contractor added a cold air return and threw the whole system out of balance. We find the problem and direct the right fix, even when that's a specialist.

CAZ Testing Live prop: combustible-air analyzer + manometer

• ✓What CAZ is Combustion Air Zone. We test it any time a home has a naturally drafted gas appliance — water heater, gas dryer, gas stove.
• ✓The risk after sealing Once the house is tight, your exhaust fans (bath, kitchen hood, dryer) still pull air out, but now there's less air to pull from.
• ✓Worst case Those fans can depressurize the house enough to pull air down the flue of the water heater instead of letting the exhaust go up and out.
• ✓Why that's dangerous Carbon monoxide can backdraft into your living space. The appliance looks fine — it just can't exhaust. This has caused real CO incidents around the country when companies sealed without testing.
• ✓The worst-case test Close every door feeding air to the appliance (smallest air supply), turn on every exhaust fan at once (maximum pull), run the appliance for exactly two minutes.
• ✓What we measure Test the flue with a combustible-air analyzer for backdrafting gases, and the room with a gauge to see how negative it went.
• ✓Before and after We log it before and after the job. The graph shows why it's backdrafting and how to correct it.
• ✓What you get Documented proof that even in the worst case, your house does not backdraft after we're done.

Air Sealing Proposed — confirm w/ Michael + Ray

• ✓What it is Closing up all the little gaps and holes where your conditioned air is escaping. It's the fix that follows the testing.
• ✓The trap Sealing without testing. You can't see most of the leaks, so you miss the hidden ones.
• ✓Why the miss is dangerous Once most of the holes are closed, all the leftover moisture and air funnels through the few spots you missed — concentrated on that one point like a pressure washer.
• ✓Half-done is worse than nothing That concentration causes mold, rot, and structural damage faster than the leaky house ever would have.
• ✓So we test the whole time we seal Techs seal while I re-test each spot live, catching anything that didn't take.
• ✓Real-time catch Sometimes a spot won't seal because of dust — the sealant can't grab. We sweep it, re-seal, and watch the number go perfect.
• ✓Seal the whole pathway We seal the top of the wall AND the switch or fixture itself, so the channel to the attic is gone for good.
• ✓The result An evenly sealed house with no hidden concentration points, verified by the numbers, not by guesswork.

The Report Proposed — confirm w/ Michael + Ray

• ✓Everything gets documented Every test we run ends up in a full professional report you keep.
• ✓Whole-house before + after Your ACH number when we started and when we finished, so you see exactly how much tighter your home is.
• ✓Room by room Every room's individual result — which ones were the problems, and where they landed.
• ✓Down to the fixture The pan data: the switches, outlets, and can lights we found and sealed.
• ✓Safety proof Documented evidence that even in the worst case, your house doesn't backdraft carbon monoxide after we're done.
• ✓Why it matters Most companies hand you a bill and a handshake. This is proof the work is real, and it's yours to keep — for peace of mind, or if you ever sell.
• ✓Accountability on us The numbers either moved or they didn't. You can see it in black and white.

Overview — Why We Test Proposed — confirm w/ Michael + Ray

The series opener that frames everything else. Fine to film last, once Ray's warmed up, since it summarizes the whole approach.

• ✓How it's usually done Someone eyeballs it, adds insulation or seals a few spots, and hopes. No before number, no after number, no proof.
• ✓Our approach is the opposite We test first, so we know exactly where your house is leaking, out of balance, or unsafe.
• ✓Fix, then prove it We make the fix, then test again to prove it worked. Numbers, not guesswork.
• ✓Why testing-first matters Skip it and you miss hidden problems — worse, a half-done job can concentrate the problem and cause mold, rot, or even pull carbon monoxide back into the house.
• ✓No partial jobs There's no bronze, gold, platinum here. It's done right or we don't put our name on it.
• ✓What "right" looks like Whole-house diagnostics, room by room, down to the fixture, plus a safety check on your gas appliances — all documented.
• ✓The bottom line for you A home that's more comfortable, healthier to breathe in, cheaper to run — and proof in hand that it's true.
