A new build leaves behind three separate piles, and they do not go to the same place. Cardboard and appliance crates are a recycling lane. Packing foam, plastic film and blue tape are trash. The trim scraps, paint cans and tile pieces the trades left in the garage are construction debris. Sorting them is the whole job.
Nobody warns you about this part. You close, you move in, and within a week the garage you were going to park in is stacked to the ceiling with flattened boxes and the crate your refrigerator came in. The house is finished. The garage is a staging yard.
Cardboard is the biggest pile and the easiest one
A move into a new house generates more cardboard than any other single event in a household's life. Every box you packed, plus every box that came with something new: the mattress, the washer, the grill, the patio set, the eight things that arrived while you were unpacking the first eight things.
Cardboard is one of the few materials where recycling actually works at scale, which EPA covers in its recycling basics guidance. It has a real market, it gets made back into cardboard, and it does not need to go to a landfill.
Flatten everything, because a stack of flat cardboard takes a fraction of the space a pile of open boxes does. Then keep it dry. Cardboard that sat out in the driveway through a storm is contaminated and loses most of its value to a recycler.
Your cart will take some of it over several weeks. It will not take all of it in one. That gap is where most of these calls come from.
Foam, film and the packaging that is not recyclable
This is the pile people get wrong. The molded white foam that braced your appliance corners, the plastic film wrapped around the furniture, the air pillows, the blue painter's tape, the foam sheets between the cabinet doors: none of that goes in the recycling cart.
Putting it there is worse than throwing it away, because a load of clean cardboard with foam mixed through it can get downgraded or rejected at the sorting facility. TCEQ's recycling pages are the state-level version of the same message. Keep the streams apart and both of them work better.
The appliance crate is the one that will not fit anywhere. Refrigerator and range crates are big, rigid, and stapled together. They do not flatten the way a moving box does, and they are the single item that most often turns a manageable garage into a call to us.
What the trades left in the garage
Walk the garage corners and the attic access before you decide this is only a box problem. New builds hand over with leftovers, and they are a different category than packaging.
What turns up most: cut ends of baseboard and crown, a partial box of floor tile, leftover cabinet hardware, a bundle of shingles, half a roll of housewrap, drywall offcuts, buckets of dried thinset, and paint cans. The paint is the one to separate out before anything else moves.
The lumber, tile, drywall and roofing are construction debris and they come out on a normal job. EPA's construction and demolition materials guidance covers why that stream is kept separate from household trash in the first place: much of it is heavy, clean and recoverable, which is not true of mixed household waste.
The paint, stain, thinner, adhesive and sealant are not ours to take. Those are household chemical waste, and they go to your city's collection program. Plano runs its own household chemical collection, and every city in our area has some version of it. Leave the cans where they are and we will point you at the right program for your address.
What the town will take, and what it will not
Most of the northern suburbs run a weekly bulk collection alongside the regular cart, and it is free, so use it first when it will do the job. What catches people out is the excluded list.
Prosper's trash and recycling page is a good example of how these rules actually read. Bulk takes furniture and appliances. It does not take construction material, and it caps how much goes out in a single week. It also runs a Saturday drop-off at the public works center for anything over that line.
So the practical answer for a new build is usually split. The furniture that did not fit the new floor plan goes out at the curb on bulk day. The trim scraps, the tile, the drywall and the mountain of cardboard do not, because they are either excluded outright or they are more than one week of collection will absorb.
Prosper sends us more of this job than almost anywhere else we work, which is why our junk removal in Prosper page leads with move-in leftovers and builder-staged garages rather than the usual cleanout list. Neighborhoods there have been finishing out street by street for years now.
The furniture that did not survive the move
This is the other half of most new-build calls, and it tends to surface about three weeks in, once the rooms are laid out and the truth is obvious.
The sectional that fit the old living room does not fit this one. The dining set is the wrong scale. The guest bed has been leaning against a wall in the bonus room since move-in day because there is nowhere to put it. The old mattress came along and nobody has slept on it.
Usable pieces go to local donation partners rather than a landfill, and that is the first thing we try with anything still in decent shape. If you are in Prosper we handle that side under furniture removal in Prosper. Our post on what to haul instead of moving is the version of this to read before the truck loads, not after, though it is never too late to make the cut.
How the job runs
Send a photo of the garage. That one photo answers most of what we need to know, because a new-build garage tells the whole story: how much cardboard, whether there is an appliance crate, and whether the trades left anything in the corner.
A crew looks at what is going and gives you a firm number before anything is loaded. The quote is the bill, and disposal is included. We sort the cardboard out of the load on our end, so you do not have to run two trips yourself.
One timing note. If your builder warranty walkthrough is coming up, clear the garage before it rather than after. It is easier for everyone to look at a wall when nothing is stacked against it. When you are ready, send us the photos and tell us the week. There is no rush on our end.
Frequently asked questions
Can you take just the cardboard?
Yes. A garage of flattened boxes and appliance crates is a normal job for us, and cardboard goes to a recycler rather than a landfill.
Do we need to flatten the boxes first?
It helps and it is not required. Flattened cardboard loads faster and takes less room, but we will break them down ourselves if you have not gotten to it.
Will you take the leftover paint the builder left?
No. Paint, stain, thinner and adhesives are household chemical waste and go to your city's collection program. Set them aside and we will tell you where your city takes them.
What about the lumber and tile in the garage corner?
That comes out with us as construction debris. Most city bulk programs exclude construction material, which is why it is still sitting there.
Can you come before our builder walkthrough?
Usually yes. Call before noon and the same afternoon is typical across the northern suburbs, though typical is the honest word rather than guaranteed.
A new house is the one time a garage fills up with things nobody bought on purpose. The rest of what we haul is on the services page.
