Mighty specialists for the toughest jobs in the Rockies.
We run our business the way the best craft brewers run theirs: a focused lineup, made to a high standard, with people who care about every order.
About Altitude Construction Supply
Altitude Construction Supply is a trusted distributor of construction supplies focused on CSI Divisions 03, 07 and 09: concrete, thermal and moisture protection, and finishes.
Our team brings years of industry experience and a simple commitment: top-notch products and exceptional service for every customer. We carry only products from reputable brands that meet high standards of durability and performance, along with the tools, equipment and supplies to get the job done efficiently.
We're longtime locals. We know the industry, we know the people who install these systems, and we know how freeze-thaw cycles, sun and snow test a building in the Rocky Mountain region.
Quality over quantity
The best craft brewers don't try to make every style for every market. They pick their recipes, source the best ingredients and obsess over every batch. That's how we approach supply: focused, not small.
We keep a focused lineup of systems we know inside and out, so when you call with a question about a deck coating, a failed joint or a fireproofing spec, you get a real answer from someone who has seen it before.
Quality products, real service and technical support, backed by consistent invoicing and delivery.
What you can count on
Brewed for performance.
A focused lineup of proven products from manufacturers we trust. We'd rather know a few great systems inside and out than stock everything.
Not a warehouse. A workshop.
Real people who know the products and know your job. Relationships, not transactions.
Mighty in the details.
Help choosing systems, reading specs and getting application right, plus hands-on training through Altitude University.
Every order, handcrafted.
Accurate, consistent invoicing and dependable delivery, job after job. The boring stuff, done right every time.
Trusted brands
We carry products from reputable manufacturers that meet high standards of durability and performance. Every line earns its place on our shelves.
Contractor preferred
Built around the way contractors work: knowledgeable people at the counter, straight answers, accurate invoices and deliveries you can plan around.
Complete solutions
From primer to topcoat, backer rod to caulk gun, we supply the full system plus the tools, equipment and accessories to finish the job.
Business the way it used to be done
Remember when your supplier knew your name, picked up the phone and told you what would actually work? We never stopped doing business that way.
Relationships, not transactions
We get to know you, your crews and your jobs. A handshake still means something here, and we want to be your supplier for the next job and the one after that.
Real people, real answers
Call and you'll talk to someone who knows the products. No phone trees, no ticket numbers, no runaround.
Tailored recommendations
We listen to the job first, then recommend the system that fits your substrate, schedule and budget. Not a one-size-fits-all answer.
