The single biggest misconception new construction buyers in Celina arrive with: that the home is finished on move-in day.
It's not. A new home is commissioned, not finalized. The first 90 days are where you find out what the builder calibrated for the punch-list day vs. what actually works for a family of four with a dog and a real cooking schedule. The settling reveals where the structure wants to move. The first heavy rain reveals drainage decisions you couldn't see during the walkthrough. The first 95° afternoon reveals whether your HVAC was balanced for July or for a 72° showing day.
I've walked through hundreds of new builds across Celina, Light Farms, Mustang Lakes, Cambridge Crossing, and the surrounding North Texas communities. The buyers who treat the first 90 days as a continuation of the build save tens of thousands compared to the buyers who treat move-in day as the finish line.
Here's the punch-list I run on every new-construction home I walk.
1. Document everything — for warranty, before you forget
Most Texas production builders offer a 1-year fit-and-finish warranty. It covers settling cracks, drywall pops, nail pops, paint touchups, door alignment, grout issues, baseboard separation, and a long list of small finish problems. The catch: you have to submit the claim, in writing, with photos, before the warranty expires.
Start a folder (digital is fine) on day one. Every time you spot something — even tiny stuff — photograph it with date metadata intact. Note the room and location. At month 10, submit one comprehensive warranty list. Most builders will fix 80–90% of submitted items if the documentation is clean.
The 1-year fit-and-finish warranty in Texas is the most-missed warranty in the country because buyers don't realize how aggressively builders enforce the cutoff. A drywall crack you photograph at month 11 is covered. The same crack at month 13 is your problem. Calendar a "submit warranty list" reminder for month 10.
2. Commission your HVAC for actual occupancy
The builder's HVAC contractor balanced your system for the day of the punch list — empty house, every door open, everything dialed for a 25-minute inspection. That's not how you live.
Within the first 60 days, schedule a real HVAC commissioning service. Have the tech balance airflow for your actual occupancy: bedrooms cooler than living spaces, the upstairs vs. downstairs differential corrected, ductwork checked for the leaks builders never address. $150–$300, takes 90 minutes, prevents the most common new-build comfort and energy complaints.
While they're there, get them to flush the condensate drain line and confirm the refrigerant charge — both things builder contractors often skip on commissioning day. (Full HVAC checklist is in our pre-summer HVAC post.)
3. Walk the property during the first heavy rain
This is the single highest-leverage 30 minutes of the first 90 days. Wait for a real North Texas storm — the kind that drops 1.5+ inches in an hour. Then walk the perimeter while it's happening.
You're looking for: standing water within 6 feet of the foundation, water pooling against window wells or basement entries, downspouts that discharge against the slab instead of away from it, gutters overflowing because they're undersized or routed wrong, and any slope toward the house instead of away.
Drainage problems are covered by builder warranty IF caught early. They become $5,000–$15,000 problems if you discover them three years in.
4. Test every appliance, fixture, and safety device
Run the dishwasher on its longest cycle. Run the washing machine on hot. Take a hot shower in every bathroom simultaneously (have your family help). Run the disposal. Test every smoke detector and every CO detector. Open every window and door — watch for misalignment. Toggle every light switch. Test the garage door auto-reverse safety. Run the irrigation system zone by zone.
Anything that doesn't work perfectly: photograph, log, and submit to the builder warranty queue within the first 30 days. The builder's punch-list day didn't catch what you'll catch.
5. Set up foundation watering before summer hits
North Texas clay soil shrinks dramatically when dry. New construction homes are most vulnerable in their first year because the soil hasn't fully settled around the slab. If your move-in is between April and September, set up foundation watering on day one.
$40 in soaker hose plus a $20 timer is enough. Run for 30 minutes, 3-4 times a week during summer. (Detailed setup in our maintenance calendar post.) The buyers who skip this step are the ones with foundation pier estimates two years later.

The mindset shift that pays for itself
The buyers who get this right treat their builder relationship the way smart people treat their car dealer: politely insistent, well-documented, and never assuming "they'll handle it." The buyers who get it wrong assume that paying $500K for a house means everything was done right. Sometimes it was. Often parts of it weren't.
The first 90 days are the cheapest 90 days. Everything you catch now is free. Everything you catch later is yours.
