Golden Standard, included
215 details already in your plan
What it pays back over 20 years: 2–4×
Fewer repairs, less maintenance, and a home that inspects and appraises stronger — all of it already in your plan, never a separate line.
Built to last
The blocking, flashing, and waterproofing details that decide whether the house is still tight in year 20.
Less to fix
Pressure-reducing valves, isolation valves, recirc loops — the things that turn a six-year fixture into a twenty-year one.
Worth more later
Buyers can’t always name what makes a home feel premium. Inspectors and appraisers can. These are what they look for.
A contractor on a deadline can’t plan 50 years ahead for your house. We do that part, so yours can build it.
Most renovations are graded on what a buyer sees in the first thirty seconds: the cabinets, the countertops, the light fixtures, the tile. Those things matter. They are not, however, what determines whether the house is still quietly performing — dry, tight, comfortable, efficient — in year fifteen.
The things that determine that are buried in the wall cavities, under the slab, behind the stucco, and inside the attic. They cost a few hundred dollars and an extra hour of a tradesperson’s time when the studs are open. They cost tens of thousands of dollars, or are simply impossible, to add later.
A contractor working on five jobs at once, hustling between Home Depot runs, lender calls, and the latest scope change, does not have the bandwidth to think about any of these things. They are doing their best to finish the job and get paid. We do not blame them for that. We built ExpandEase so the contractor on your project doesn’t have to.
The Golden Standard is a list of 215 specific actions, organized by trade, that we bake into every project we build. Your contractor quotes them as part of the scope. They get verified by photo at sign-off. They get carried forward, as a document, to the next owner of the home.
The ones that pay for themselves first.
Five of the 215
Cat6a Ethernet to every room before the drywall closes
No. 1 · Low-voltage
About $500 in wire. One day of one person’s time.
Why: The single highest-ROI low-voltage decision available in a modern home.
WiFi 6E is faster than the WiFi most people remember, but it still depends on physics. The signal degrades through every wall it crosses. The only way to keep every corner of a 3,000 square foot home at full speed is wired backhaul to ceiling-mounted access points, and the only way to do that without ripping into finished drywall is to pull the wire before drywall goes up. The wire costs forty cents a foot. The retrofit, ten years from now when 10-gigabit is the standard and your home office is a video studio, costs eight thousand dollars in opened walls and patched drywall. This is the moment when a contractor either thinks ahead or doesn’t.
A pressure-reducing valve at the main water line
No. 2 · Plumbing rough-in
$150 for the valve. Twenty minutes of a plumber’s time.
Why: Phoenix municipal water enters most homes at 90 to 110 psi. Every fixture in the house is designed for 50 to 70.
Every washing machine valve, every dishwasher fill solenoid, every refrigerator ice maker line, every toilet fill valve, every faucet cartridge — all of them are sized for residential pressure, which is 60 psi. When 100 psi shows up at the meter, these components don’t fail today. They wear at twice the rate for ten years and then start failing one at a time. A pressure-reducing valve is a single piece of brass with a screw on top. It is required by code in most of Phoenix. It is also frequently omitted on remodels because the inspector doesn’t catch it and the homeowner doesn’t know to ask. A contractor who installs it without being told is a contractor who is paying attention.
High-temperature self-adhered underlayment beneath the entire tile field
No. 3 · Roofing
About $1.50 per square foot of roof.
Why: A clay tile roof in Arcadia sees underlayment temperatures of 175°F. Standard 30-pound felt becomes brittle in seven years. The tile lasts fifty.
A tile roof is two roofs in one. The tile is the part you see — the part that lasts half a century if it doesn’t get walked on. The underlayment, lying flat under the tile, is the actual waterproofing. Every monsoon, water gets past the tile and runs along the underlayment to a flashing or a valley. In Phoenix attic heat, the cheap felt underlayment that builders default to has the lifespan of a midsize sedan. The tile outlives it three times over. So the homeowner, fifteen years from now, will find themselves taking the tile off — at twenty thousand dollars — to replace the part underneath that the contractor saved a thousand dollars on. The right underlayment costs $1.50 a foot. It is the difference between a roof that lasts as long as the tile and a roof that doesn’t.
A photograph of every wall stud bay before the drywall covers it
No. 4 · General contractor
Free. A phone, an hour, and the discipline to do it.
Why: Indispensable in 2040 when someone wants to remodel a bathroom and needs to know what’s in the wall.
The reason your contractor charges you fifteen thousand dollars to renovate a bathroom is mostly because they don’t know what’s in the wall until they open it. Is there a vent stack behind that tile? Is the supply line copper, PEX, or galvanized? Where exactly does the drain run? Is there blocking for the new fixture? The honest answer for almost every house is: nobody knows, because nobody documented it. A contractor who walks the studs with a phone before drywall and uploads geo-tagged photos to a shared folder is doing a thing that costs an afternoon and saves the next owner — including the current owner, six years from now when they decide to add a bidet — thousands of dollars of demolition just to look. This is also the single best artifact a future appraiser will be handed when valuing the home. A "renovation done right" is, in part, a renovation that someone can prove.
A whole-house water softener loop pre-plumbed in the garage
No. 5 · Plumbing rough-in
$200 in PEX and tees. Thirty minutes during rough-in.
Why: Phoenix water averages 12 to 17 grains hardness — among the hardest tap water in the United States. Every water heater, every coffee maker, every dishwasher dies early without a softener.
You do not need to install a water softener today. You just need to leave the loop. The loop is two PEX stubs in the garage, capped, where a future softener will tie in. Without the loop, a softener install is a $3,500 job: cut into a finished wall, run new lines, restore the drywall. With the loop, it is a $1,200 weekend project. More importantly, the loop is a signal. Any future buyer who knows anything about Phoenix water will see the capped stubs in the garage and understand, immediately, that this house was built by someone who was paying attention. Loops like this one — for future solar, for a future EV charger, for a future gas line to a patio firepit — are the cheapest and most powerful things ExpandEase puts in a plan. They cost the price of a nice dinner. They earn back five, ten, twenty times that for the life of the house.
The full Golden Standard, trade by trade.
See exactly what gets included in yours.
On your plan, only the items that are naturally weaveable into your scope appear — if you’re not re-roofing, we don’t add a roof-underlayment item to your bill. Each one that does apply gets quoted by your contractor, verified by photo, and signed off before the next trade starts.
Cost and return figures are industry estimates calibrated against published construction-science and lifecycle-maintenance data, and a 3,000 sq ft Arcadia-area reference build (4 bed, 3 bath, slab-on-grade, stucco, tile roof). Your actual numbers will vary by scope and home.
