A home can look polished during a showing while leaving important questions unanswered. Fresh paint does not explain an old ceiling stain, and a pleasant room fragrance does not tell you how well the kitchen exhausts cooking pollutants.
That ventilation question deserves attention. The Guardian, in its October 16 report on commercial kitchen air, summarized US research finding that nitrogen dioxide in restaurants using gas could exceed World Health Organization limits. The story concerned commercial kitchens, not houses, so its findings should not be transferred directly to a home. It does, however, offer a useful reminder: combustion and ventilation belong on a buyer's condition checklist.
Print or save the checklist below. Use it to record observations and questions, not to replace a qualified home inspection. A concerning answer can guide your next step, whether that means requesting a document, obtaining an appropriate specialist's evaluation or reconsidering the property.
Moisture and drainage
□ Look beneath sinks, around toilets and near tubs for staining, swollen materials or musty odors.
□ Check ceilings, basement walls and the area around windows for discoloration, peeling finishes or visible repairs.
□ Ask whether the basement, crawl space or yard has taken on water, and request available invoices for drainage, foundation or waterproofing work.
□ Note whether gutters, downspouts and ground surfaces appear to direct water away from the structure.
□ Ask the inspector to explain the likely source of any moisture evidence, what can be tested and what remains uncertain.
Ventilation and combustion
□ Identify where the kitchen range hood sends air. A recirculating unit and an exhaust duct leading outdoors are not the same arrangement.
□ Turn on bathroom exhaust fans where permitted, and ask whether they vent outdoors.
□ Record the fuel used by the range, furnace, water heater, fireplace and other combustion equipment.
□ Ask for installation, service and repair records for heating and ventilation equipment.
□ Locate smoke and carbon monoxide alarms. Ask the inspector to comment on placement and condition under applicable local requirements.
□ Ask whether attached garages, workshops or utility rooms have pathways that could allow odors or pollutants into living areas.
Water system and records
□ Identify the water source, the main shutoff and any treatment equipment.
□ Run taps, when allowed, and note slow drainage, unusual color, persistent odor or large differences in pressure.
□ Request available water utility records, private well records, treatment-system manuals and recent laboratory results. The relevant documents depend on the property's water source.
□ Ask the seller what filters, softeners or other devices require replacement media, salt, cleaning or professional service.
□ Ask the inspector what portions of the supply and drain systems were visible, and which were inaccessible.
Documents to request
□ Seller disclosures and amendments.
□ Permits and final approvals for significant renovations, additions or system replacements.
□ Roof, plumbing, HVAC, drainage, remediation and pest-treatment invoices or warranties.
□ Insurance claim information that the seller is required or willing to provide through the appropriate transaction process.
□ Manuals and service histories for equipment that will remain with the home.
A record is not proof that a problem is fully resolved. Match dates and described work to what you can see, then ask your inspector which gaps matter. Keep copies with the inspection report so later decisions do not depend on memory.
Questions for the inspection period
□ What could not be inspected, and why?
□ Which findings need prompt attention, and which are maintenance items?
□ Does any observation call for evaluation by a roofer, plumber, electrician, HVAC contractor, structural professional or other qualified specialist?
□ What additional testing, if any, would help answer a specific question about this property?
□ Which repairs may affect ventilation, moisture control or water quality if completed incorrectly?
□ What should be checked again during a final walk-through?
Make the checklist personal
Add concerns that affect how your household actually lives, including sensitivity to noise or odors, space for mobility equipment, and the ability to maintain filters or stairs. A checklist can reduce ordinary decision overload, but it is not mental health care. A person whose housing search is complicated by trauma may also want information about PTSD treatment near St. Peters, Missouri from an appropriate provider.
Before an offer or inspection deadline, circle the unanswered items and assign each one to the seller, agent, inspector or relevant specialist. If you want help turning those findings into property priorities, discuss your home search before making the next decision.
