Are you open to the Public?

Yes, in fact we’ve been open to the public since 1933. 

Do I have to load myself?

After you weigh in, we have a small loader which will load as much or as little as you need, paying only for what you get.  If you want, you can also shovel product into the trunk of your car or the back of a pickup with a canopy. 

Can I buy less than a ton or cubic yard?

For products sold by the ton, you can purchase any amount you want, paying only for what you get.  We weigh your vehicle in; you get loaded; we weigh your vehicle out; and you pay only for how much you have.  For products sold by the cubic yard (CY), we have a 1/2 yard minimum.

Can I just buy a bucket?

Sure, depending on the product a 5-gallon buck costs just $1 or $2.

How much is a ton?

A ton is 2,000 pounds (i.e. lbs).  A full size pickup can usually carry a little over a ton of material, while a smaller pickup can typically handle half to three-quarters of a ton (i.e. 1,000 to 1,500 lbs).

How much is a cubic yard?

A cubic yard is 3’ x 3’ x 3’ which equals 27 cubic feet or one yard.  Cubic yard is abbreviated CY.  A full size pickup can usually carry 1 to 1.5 CY of material, while a smaller pickup can typically handle one CY.

How does a ton relate to a cubic yard?

Every product has different densities which make some products weigh much more per cubic yard than others.  For example, a cubic yard of beauty bark is much lighter than a cubic yard of crushed gravel.  Most sands and gravels weigh 1.2 to 1.5 tons per cubic yard.  For instance, one cubic yard of crushed gravel will weigh about 2,900 lbs or 1.45 tons.  Click here for a link to approximate conversion tables for most of our products.

Do you deliver?

Absolutely, call and we’ll quote you delivered prices.

How much does it cost to deliver?

That depends upon where you’re located and the amount of product you want.  Many deliveries become more economical about 3 CY or more.  Smaller quantities are typically cheaper buying in a pickup or trailer at our retail sales yard.  However, we will deliver any quantity you need.

Why does delivery of 1 or 2 yards cost so much?

We often tell customers it costs just as much to deliver a teaspoon full as it does to deliver 12 CY.  That’s because the cost of delivery doesn’t change, but the more product we put on the dumptruck, the cheaper it costs for each cubic yard.

Why don't you offer "free" delivery?

There is no such thing as “free delivery.”  While some companies offer “free” delivery it isn’t really free.  The cost of operating dumptrucks, scheduling, paying employees, and many other expenses are simply hidden in the price.  We tell you what the delivery costs because we value your business whether you pick up the material yourself or have us deliver.  For ease of quoting prices, we offer standard pricing for 10 CY, 12 CY, and 15 CY loads.

How do I know whether your delivered pricing is any good?

We’re so confident of our pricing we’ll give the names and phone numbers of our competitors so you call them to make sure that Palmer’s prices are the best around.

I'm a contractor. Do you have contractor pricing?

We offer contractor pricing in two ways.  When you purchase more than 3.5 tons or 3 CY in one load, you get what we call dumptruck pricing as opposed to pickup prices.  If you plan to be a regular customer, we offer credit accounts with even better prices and more convenience.  If you have a Washington state Resale tax registration, please provide us with a copy and we won’t charge sales tax. 

What does 'Palmer Coking Coal' mean?

Palmer comes from the generally forgotten town of Palmer-Kanaskat (near Durham), located in east King County.  Coking refers to a type of coal which could be partially “cooked” to extract impurities.  Coal was the mineral we mined during the Great Depression, with thirty or more companies competing for market share in a declining industry.  By selling good quality products, Palmer Coking Coal found favor with consumers and businesses in supplying Washington’s fuel needs.  We now sell different products but our motto remains the same: “Good products – Good prices – Good service.”

Do you have a Facebook page?
