Build Service.
Construction services in Western Colorado — local-contractor referral everywhere else
If your site is in Western Colorado or the immediately surrounding region, our own crew can run the build. NatMar acts as your licensed general contractor: We follow the manufacturer's specs, handle the permits, and bring in trusted subs when needed. Giving you the same point of contact from quote to keys.
For build sites outside our Colorado footprint, NatMar doesn't take the construction on. Instead we introduce you to a local erector or GC who can build the system we supplied. These local contractors are independent businesses. The introduction is a referral only. They're not an official NatMar partner, and we don't take any money for this service. Once we connect you, you contract directly with them and they own the construction relationship from there.
No matter what your build path looks like, NatMar's role is helping you navigate the project with real-world building experience behind it. Whether we're managing construction directly in Colorado or handing the project off to a trusted local contractor elsewhere, our focus is making sure you get the right steel building package, the right guidance, and the support needed to keep the project moving successfully from planning through completion. We don't just supply buildings, we help people build them.

Testimonials
“Nate and his experienced crew did a fantastic job erecting our 35' x 40' steel shop. I found NatMar through an internet search. I selected NatMar because they were local, displayed excellent expertise, and were competitively priced. Their communications and administration were flawless. The crew was always punctual, polite, and worked with care and attention to detail. We had some challenges along the way; however, everything was dealt with without any fuss or penny-pinching.”
“Nathan and his crew are top notch! They were able to fit in my small project between their bigger jobs which got me finished real quick. They do great quality work and I would highly recommend NatMar to anyone.”
“Complete project was good quality, on time, on budget and craftsmen were very professional. If I could find anything not perfect would be the screws scattered around post completion which is petty. Great job guys!”
“Nathan Margosian of NatMar Construction and his crew have been nothing but excellent. They have just completed a third building for me in the last year. Nathans customer service, punctuality at completion on time, and completing on budget is unmatched, all at a very fair and reasonable rate. I highly recommend Nathan and NatMar Construction for any of your needs for metal buildings.”
