Homeowner Summary

Moving into a new home is exciting, but it also means you're suddenly responsible for systems you may know nothing about. Where's the main water shutoff? How old is the HVAC system? When was the roof last inspected? What's covered under warranty? These are questions you need answered before something goes wrong, not after.

The first 30 days in a new home should include a systematic discovery of every major system: its location, age, condition, maintenance requirements, and warranty status. This knowledge will save you money, prevent emergencies, and help you plan your maintenance budget. The average homeowner spends $3,000-$5,000 per year on maintenance and repairs. Knowing what to expect is the first step to controlling that cost.

The most critical first step is learning where every emergency shutoff is located. Knowing how to shut off the water in 30 seconds can be the difference between a minor leak and $20,000 in water damage.

How It Works

Every home has a set of core systems. Here's what you need to know about each one:

Critical Shutoffs (Learn These Day One)

ShutoffTypical LocationHow to Operate
Main waterNear where water enters the home (basement, utility room, or exterior)Turn clockwise (gate valve) or quarter-turn (ball valve)
Water heaterOn the cold water inlet pipe above the heaterTurn clockwise or quarter-turn
Main gasAt the gas meter (exterior), requires a wrenchQuarter-turn so handle is perpendicular to pipe
Individual gas appliancesNear each gas appliance (furnace, water heater, range, dryer, fireplace)Quarter-turn
Main electricalAt the main breaker panelFlip the main breaker to OFF
Individual circuitsAt the breaker panel (each breaker should be labeled)Flip individual breakers to OFF
Sprinkler systemAt the backflow preventer (usually exterior near meter)Turn clockwise
Sump pumpUsually a standard outlet in the basementUnplug (but only for testing; never leave disconnected)

System-by-System Orientation

HVAC: Locate the indoor unit (furnace/air handler), outdoor unit (condenser), thermostat, air filter location, and condensate drain. Record the model number, serial number, and installation date (on the data plate). Filters should be changed every 1-3 months.

Plumbing: Locate the main shutoff, water heater, water softener (if present), sump pump (if present), and cleanout access (for sewer line). Know the water heater age (first 4 digits of serial number often encode the date).

Electrical: Locate the main panel and any subpanels. Verify breakers are labeled. Identify GFCI outlets (kitchen, bathrooms, garage, exterior, basement) and test them. Note the service size (100A, 150A, or 200A — found on the main breaker).

Roofing: Determine the roof type, approximate age, and last inspection date. If available, get the installer's name and any warranty documentation.

Exterior: Understand grading and drainage around the foundation. Locate the hose bibs and their interior shutoffs (for winterization). Identify the property boundaries if relevant to landscaping or fencing.

Appliances: Record the model number, serial number, and purchase/installation date for every appliance. Check warranty status online using the serial number.

Maintenance Guide

DIY (Homeowner)

First 30 Days:

  • Locate and label every shutoff (use plastic tags or tape)
  • Change all HVAC filters
  • Change all door locks (security best practice)
  • Test all smoke and CO detectors; replace batteries
  • Test all GFCI outlets
  • Run every plumbing fixture to identify any issues
  • Open and close every window
  • Test the garage door opener safety reverse (place a 2x4 on the ground; door should reverse when it contacts it)
  • Find and organize all manuals, warranties, and maintenance records left by the previous owner
  • Register warranties for any new appliances or systems
  • Set up a maintenance calendar (or Shipshape account)

First Year:

  • Schedule HVAC service (spring for AC, fall for heating)
  • Have the chimney inspected if the home has a fireplace
  • Get the dryer vent cleaned
  • Winterize exterior hose bibs (in cold climates)
  • Test the sump pump before the wet season
  • Monitor for any seasonal issues (ice dams, basement moisture, grading problems)
  • Learn the normal sounds of your home (refrigerator cycle, furnace startup, well pump) so you can recognize abnormal sounds

Professional

  • HVAC service: schedule within the first 3 months if the previous service date is unknown
  • Plumbing inspection: recommended if the home is 30+ years old (especially sewer line camera inspection, $150-$300)
  • Pest inspection: if not done during the purchase, schedule within 6 months (especially in termite-prone regions)
  • Roof inspection: if the roof is 15+ years old, get a detailed inspection from a roofing contractor (separate from the home inspection)
  • Tree assessment: if large trees are near the home or power lines, have an arborist assess health and risk

Warning Signs

Issues that may emerge in the first months of ownership:

  • Water stains appearing on ceilings or walls (especially during first major rain)
  • Musty smell in basement or crawlspace (moisture issue)
  • HVAC cycling frequently or not maintaining temperature
  • High utility bills relative to the home's size and season
  • Pest evidence (droppings, sounds, wood damage)
  • Efflorescence (white mineral deposits) on foundation walls
  • Water pooling near the foundation after rain
  • Circuit breakers tripping regularly
  • Toilets running or faucets dripping
  • Odor from drains (possible dried-out traps or venting issue)

When to Replace vs Repair

For newly purchased homes, the context is unique because you're inheriting someone else's equipment:

  • If the inspection identified an issue and you negotiated a credit: Use the credit for the intended purpose. Get multiple quotes.
  • Equipment near end of life: Use the inspection report and Shipshape age data to plan replacements. Don't wait for failure — budget and schedule proactively.
  • Warranty items: Check all warranties immediately. Many manufacturer warranties transfer to new owners but may require registration within 30-60 days of closing.
  • Home warranty: If you received a home warranty (common in real estate transactions), understand what it covers, what the service call fee is ($75-$125), and how to file claims. Home warranties typically cover mechanical failures of systems and appliances.

Common Failure Modes

Issues most commonly discovered by new homeowners in the first year:

  • Water heater failure (often the oldest appliance in the home, 8-12 year life)
  • HVAC refrigerant issues (not always caught in inspection if weather prevented testing)
  • Sewer line problems (root intrusion, bellied pipe — pre-purchase sewer scope prevents surprises)
  • Roof leaks during first major storm (flashing failures not visible during dry inspection)
  • Basement water intrusion during first heavy rain season
  • Pest issues becoming apparent in warm months
  • Grading/drainage problems causing foundation moisture

Diagnostic Procedures

New homeowner system orientation:

  1. HVAC test: Run both heating and cooling for 15+ minutes. Verify temperature differential (16-22 degrees F for cooling, 30-70 degrees F rise for heating). Check all registers for airflow.
  2. Plumbing flow test: Turn on the highest and farthest fixture. Does pressure drop significantly? Run for 5 minutes and check under all sinks for leaks.
  3. Electrical panel audit: Open the panel cover. Verify all breakers are labeled. Look for signs of overheating (discoloration, melted wire insulation). Test GFCI outlets throughout the home.
  4. Water quality baseline: Consider a basic water test ($30-$50 home kit) to check for lead, hardness, and pH, especially in homes with older plumbing or well water.
  5. Moisture baseline: Check basement/crawlspace humidity with a hygrometer. Greater than 60% relative humidity indicates a moisture issue needing attention.

Code & Compliance

  • As a new owner, you are not required to bring the home up to current building code (unless you pull permits for renovations). However, you should be aware of any grandfathered conditions noted in the inspection.
  • If the previous owner made unpermitted improvements, you have inherited the liability. Consult with your agent or attorney about options.
  • Some municipalities require point-of-sale inspections and compliance with specific requirements (smoke detectors, CO detectors, water heater strapping, sewer lateral inspection). Verify compliance has been completed.

Energy Impact

Your first year of utility bills establishes the baseline for your home's energy performance. Track monthly usage (kWh for electric, therms for gas) to identify seasonal patterns and compare against benchmarks for your home's size and climate zone. Unusually high bills may indicate insulation deficiencies, air sealing needs, or equipment operating below rated efficiency.

Request utility usage history from the utility company or the previous owner. Comparing your usage to theirs helps identify whether any issues are building-related or usage-related.

Shipshape Integration

  • New Homeowner Onboarding: Shipshape's onboarding flow guides new homeowners through a complete home system discovery. Enter equipment data, take photos, record shutoff locations, and set up maintenance schedules in a single session.
  • Equipment Age Calculator: Enter model/serial numbers and SAM automatically decodes the manufacture date, estimates remaining useful life, and sets replacement planning alerts.
  • Warranty Tracker: SAM tracks warranty expiration dates for all equipment and appliances. Alerts fire before warranties expire, prompting service calls while coverage is still active.
  • Home Health Score: New homeowners receive an initial Home Health Score based on equipment ages and known conditions. This score becomes the baseline for tracking improvement.
  • Maintenance Calendar: SAM generates a complete maintenance calendar based on the home's specific systems, equipment ages, and climate zone. No more guessing what needs service and when.
  • Dealer Opportunity: The new homeowner transition is the single best time to establish a dealer relationship. Partner with real estate agents to offer a "New Homeowner Package": free Shipshape account setup, initial HVAC service, and a whole-home orientation walkthrough. Cost to dealer: $100-$200 in labor. Lifetime value of the customer relationship: $5,000-$20,000+. Dealers who capture new homeowners within 90 days of closing achieve 3-5x higher retention rates than cold outreach.
  • Record Transfer: If the previous owner used Shipshape, the home's complete history (maintenance records, equipment data, documentation) transfers to the new owner at closing. This is a powerful differentiator for agents and a seamless onboarding experience for the buyer.
