We are a small, family-owned building supply store in beautiful downtown Castle Rock, Washington. Castle Rock Building Supply has been serving Cowlitz and southern Lewis counties since the 1930s. Owner Ken Campbell has been serving the area since the 1960s and has been providing the building material you need since 2005. Customer service is our business, and we are able to provide it on a personal level that you can't get at larger stores.
Services
Drywall and accessories, Composition and Metal Roofing, Nails, Screws, Fasteners, Power and Hand Tools, Spray Paint, Stains and Sealers, Electrical, Lighting, Plumbing, Pre-mixed Concrete, Cement, Cement Blocks and Rebar. We can order a wide variety of Milgard Windows, Masonite Doors and Wayne Dalton Garage Doors, along with other brands.
All of our plywood has exterior glue and can be used outside. CDX is standard plywood for roofing and sheathing. AC is nice looking sanded plywood. OSB (Oriented Strand Board) is an engineered sheathing product that many people refer to as wafer board, and can be used in place of plywood in many situations.
We deal in high-quality Milgard Windows and Sliding Glass Doors, which are available in a wide variety of sizes and styles. They generally take about two weeks to come in. Masonite has been a leading door manufacturer for many years, and we are proud to sell their products. They offer wood, steel and fiberglass doors in a variety of sizes and styles.

Ok I need to vent. In times like these with the pandemic, I am sure Castle Rock Building Supply is suffering just like a lot of small businesses are. You'd think they'd be grateful to have customers come in. Well, today was the first and last time I will be going there. I was laughed at and shunned for asking if they had topsoil. Yes, I am the one you turned your back on and didn't bother to say thanks for coming in, or have a good day, or sorry we couldn't help you when I left. I almost took it personally but she was also rude to another gentleman in the store. I was speechless and appalled. Get

Went into Castle Rock Supply for a board. Met Ken, the owner and he was extremely helpful.
Told him what I needed and asked if they could cut it in half.
Ken put an associate on it immediately who led me into back and allowed me to choose my board.
While I chatted with Ken the board was cut and loaded into my pickup.
What excellant Custer Service and price for board very reasonable plus cut no cost.
Have new projects for future and will obtain all my wood supplies at Castle Rock Lumber.

If you need building supplies I highly recommend buying from Castle Rock Building Supplies. They are very knowledgeable and very helpful! Longview big stores were a lot higher on roofing materials and didn't have siding I needed. Buy local and from someone you can trust! Very happy and satisfied customer!!!!
