Notice – April 2, 2022
In order to stay current with the ever-changing lumber prices we will be adding a surcharge on all orders for our dome shells and view cupola kits. The main commodity that has been very volatile in our dome shell kits has been the 3⁄4” x 4×8 T&G plywood. The prices shown for our products that utilize these plywood components have been based on a set price that we have paid for the plywood components.

Starting April 2nd 2022, all contracts will be subject to a plywood surcharge based on the quantity of plywood used in the particular size of dome you are ordering. The date
that we receive your contract with your deposit will determine the dollar amount of the surcharge. If the price has increased $5 per sheet and your dome size uses 100 sheets, the surcharge when we write your contract would be $500.

We have absorbed many price increases in the past 2 years. We buy in large quantities to get whatever discounts we can get. The current increases in plywood prices are beyond our capabilities to absorb and to be fair to our customer base, we are temporarily instituting this adjustment. Plywood prices did come down slightly in November/December 2021. This spring 2022, the price is starting to increase.
