We Buy Transformers in Castle Rock, CO
We buy used and surplus transformers throughout Castle Rock and the surrounding Colorado market, and we pay before the unit leaves your property. We buy across Colorado and dispatch into Castle Rock, CO off the Denver lane.
There is no consignment and no waiting to see what it sells for. We buy it, we pay you, and the logistics become our problem.

You are paid before the transformer leaves your property. No consignment, no waiting on a resale.
We do not ask you to test, repair or clean anything. We evaluate the unit ourselves.
We cover the freight and the rigging. Lowboys, cribbing, permits and escorts are our cost.
Disconnection, dismantling and removal are handled by our crews at our expense.

Who sells to us here
Our sellers in this market are typically solar and wind EPC firms with leftover units, oil and gas service yards, hospital and campus engineering groups, data center operators replacing capacity and school and municipal facilities departments.
- Often because capacity was upsized and the previous unit is now spare.
- Often because the tenant left and the service was oversized for the next one.
- Often because a lease is ending and the yard has to be cleared.
- Often because a voltage conversion left the old unit stranded.
Getting a truck into Castle Rock
Distance from Denver does not change what we pay. It changes our margin, not your number. We can work inside an active facility without shutting your operation down.
Distance is our problem, not yours. We quote the transformer on what it is worth, then absorb the cost of getting it out of Castle Rock. Sellers who have been quoted by scrap dealers are usually surprised by the difference, because a scrap price has the hauling cost taken out of it and ignores resale value entirely.

How the sale works
Four steps, no cost to you
1. Send what you have
A photo of the nameplate and one wide shot of the unit is enough to start. If the nameplate is unreadable, photograph the unit anyway and we will work from dimensions and construction.
2. Get a number
We come back with a firm offer, usually the same day. It is a cash offer, not an estimate that changes later.
3. We schedule around you
Pickup in Castle Rock gets scheduled to fit your outage window, plant shutdown or building access hours. If a utility disconnect is required first, we coordinate the timing.
4. We pay, then we haul
You are paid before the unit moves. Our crew handles teardown, rigging and loading, and our truck takes it away.

Castle Rock transformer selling questions
Straight answers
Do you actually come to Castle Rock to pick up transformers?
Yes. Distance from Denver does not change what we pay. It changes our margin, not your number. We do not ask you to arrange freight or deliver anything to us.
Do I need to have the transformer tested first?
No. Testing is never a condition of our offer. We assess the unit from photos, the nameplate and our own inspection at pickup.
What if the transformer is oil-filled or might contain PCBs?
We buy it either way. If the nameplate does not confirm non-PCB status we treat the unit as presumed-contaminated and price the correct disposal path into the offer. You are told plainly which category your unit is in.
When do I get paid?
Before the transformer leaves your property. Payment is not contingent on us reselling it.
Will you buy a single transformer in Castle Rock, or only large lots?
Both. One unit is worth a call, and if you have a yard full of change-outs we will quote the entire lot as one purchase.
What if the unit is still energized and connected?
That is normal. Tell us and we will coordinate the disconnection with your electrician or the utility, then handle teardown and rigging ourselves.
