The symptom is real.
The next step should be earned.
Move from uncertainty to one bounded action through 30 decision comparisons, 24 safety-first checklists and 18 verifiable outcomes. No diagnosis theatre. No repair certification. No flat list of generic tips.
Six questions. One bounded next step.
The console routes you to information, documentation or qualified help. It does not identify a hidden fault.
What are you noticing?
Where is the clearest signal?
When does it change?
What changed recently?
Is any stop signal present?
What do you need most?
Document and monitor
Do not choose the loudest answer.
Choose the route the evidence can test.
Each card keeps two plausible actions visible, names the stop boundary and links back to established room, system and seasonal evidence.
Browse all 30 comparisons →Ventilate or dehumidify?
Choose between exchanging air and removing moisture by comparing outdoor conditions, room use, airflow and the timing of condensation.
Measure first or open the construction?
Decide whether non-destructive evidence is sufficient before any invasive opening, with explicit stop boundaries for hidden services and regulated layers.
Clean the surface or stop and escalate?
Separate limited surface housekeeping from conditions where disturbed material, extent, sewage, wiring or health concerns require qualified help.
Seal a gap or improve ventilation?
Compare unwanted air leakage with intended ventilation so that sealing one pathway does not worsen moisture, pressure or combustion safety.
Repair the finish or investigate the source?
Avoid cosmetic closure over an active mechanism by comparing drying, recurrence, adjacent conditions and the route behind the visible damage.
Monitor the pattern or act now?
Use rate of change, safety signals, active water, structural movement and repeatability to choose between tracking and prompt intervention.
Contact insurer, landlord or a professional?
Route the evidence packet to the party with authority, responsibility or specialist competence without delaying urgent safety action.
Condensation or water entry?
Compare surface temperature, weather exposure, edges, timing and drying behavior before assigning a damp mark to indoor humidity or exterior leakage.
Treat the odor or trace the source?
Avoid masking a moving signal by comparing airflow, drains, materials, weather and occupancy cycles before applying any odor treatment.
Local repair or whole-system investigation?
Decide whether the visible defect is isolated or one expression of a larger drainage, airflow, plumbing, structural or envelope pathway.
Begin drying now or wait for assessment?
Balance prompt moisture reduction with electrical, contamination, insurance and evidence-preservation boundaries.
Isolate water first or document first?
Prioritize active loss control while preserving enough time-stamped evidence for diagnosis, ownership and insurance review.
Every checklist begins with a stop rule.
Document before altering, keep checks non-destructive and end with an owner, review time and verification condition.
Open all 24 checklists →The first 15 minutes
A calm first-response checklist for immediate hazards, active water, photographs, simple isolation and preserving a trustworthy timeline.
Open sequence →24H02The first 24 hours
A structured first-day checklist for repeated observations, safe drying, contact decisions and evidence that remains useful later.
Open sequence →WATER03After a water leak
Document source, spread, affected services, material response and drying conditions without entering unsafe electrical or contaminated areas.
Open sequence →SPORE04When mold is suspected
Record extent, moisture context, disturbance risk and vulnerable occupants without treating appearance alone as a species or exposure diagnosis.
Open sequence →ODOR05For a recurring odor
Track location, airflow, drains, weather and occupancy cycles before masking or treating a signal that may travel from elsewhere.
Open sequence →COND06For visible condensation
Compare surfaces, temperature, humidity, airflow and timing while checking for water entry that can look similar.
Open sequence →ATTIC07For a cold or damp attic
Observe from safe access, document roof-deck patterns, penetrations, insulation disturbance and weather without walking unsupported framing.
Open sequence →CRAWL08For crawlspace symptoms
Use an exterior-first and access-aware checklist for ground moisture, drainage, odor transfer, pests, wiring and structural support.
Open sequence →CRACK09For cracks and movement
Create repeatable width, direction and location records and identify movement patterns that should stop cosmetic treatment.
Open sequence →SOUND10For an unusual house noise
Capture trigger, duration, location and system state while recognizing electrical, combustion and structural warning sounds.
Open sequence →AIR11For a ventilation problem
Check intended airflow, blocked paths, fan operation, outdoor conditions and pressure clues without defeating safety controls.
Open sequence →INSPECT12Before a building inspection
Prepare a concise symptom chronology, comparison areas, photographs, readings, questions and access information.
Open sequence →A next step needs an owner,
a time and a proof.
Outcomes are grouped by safe, caution and stop boundaries. None of them certify the hidden cause.
Browse all 18 outcomes →Document and monitor
Use a controlled observation window when the condition is stable, non-urgent and likely to become clearer through comparable records.
Run a safe comparison
Compare one variable at a time across affected and unaffected locations without altering the building enough to erase the pattern.
Isolate a known water source
Stop an active, safely accessible water source while preserving evidence and avoiding electrical, contamination or structural hazards.
Protect people and stop
Leave the immediate area or stop ordinary investigation when alarms, smoke, sewage, structural instability, energized water or acute symptoms are present.
Start My House tracking
Create a private longitudinal record for recurrence, measurements, photos, weather and maintenance without publishing household evidence.
Prepare an insurance packet
Organize loss timing, mitigation actions, photographs, receipts and communications without overstating cause or coverage.
Prepare a landlord or property-manager notice
Send a factual, time-stamped notice describing conditions, access needs and requested action without diagnosing the defect.
Prepare a professional handoff
Give a contractor, inspector or specialist a concise evidence packet with competing routes, safety boundaries and verification goals.
Schedule a building assessment
Use a building-envelope or general building professional when multiple systems, concealed paths or consequential scope decisions overlap.
Schedule a plumbing assessment
Use qualified plumbing help for repeated backups, concealed leakage, wastewater, pressure problems or inaccessible supply and drain routes.
Schedule an electrical assessment
Use qualified electrical help for heat, odor, arcing, repeated trips, damaged wiring or water near energized equipment.
Schedule a roof or envelope assessment
Use qualified roof or enclosure assessment for active leakage, unsafe access, flashing interfaces or recurring weather-linked entry.
Schedule an indoor-air assessment
Use qualified indoor-air or ventilation assessment when symptoms persist, sources are unclear or measurement interpretation is consequential.
Perform safe drying
Reduce moisture with ventilation, heat, dehumidification or removal only within electrical, contamination, material and occupancy boundaries.
Verify after repair
Confirm source control, drying, function and recurrence over a defined observation window rather than accepting appearance alone.
Compare another weather cycle
Use a comparable rain, wind, freeze, heat or humidity event when waiting is safe and recurrence timing can distinguish pathways.
Preserve evidence before removal
Photograph, label and record affected materials before controlled removal when insurance, ownership or later diagnosis may depend on context.
Seek urgent qualified help
Escalate promptly when safety, active damage or vulnerable occupants make ordinary self-help an unsafe delay.
Information can improve a decision.
It cannot make unsafe work safe.
HouseSymptoms helps organize evidence, compare routes and prepare handoffs. It does not certify concealed conditions, approve regulated work or replace emergency and qualified professional guidance.
