Happy International Women’s Day.

Proud to be a woman running Kostr Contracting in an industry that still sees very few of us. Every job site, every project, and every challenge is another step forward.

To the women building businesses, working trades, and leading in their fields… keep going. The industry is stronger because of you.

We work in the dirt, we build from the ground up — and none of it would be possible without those who fought to protect this country we get to call home.

At Kostr Contracting, we’re proud to stand on the ground they defended and actively defend — building, working, and living in a country shaped by their courage and sacrifice.

Respect to every soldier, veteran, family, wife, husband and child who’s carried the weight of service. You’re the reason we get to keep doing what we love, where we love doing it.

Lest we forget 🇨🇦

Kostr takes their work to some pretty picturesque places in Alberta. Several times throughout the year, Erin spends 2 days helping to set up one of the world’s most dynamic long-range shooting training grounds for Canada’s military and law enforcement agencies.

🚧 Project Update – Royal Mews Retaining Wall 🚧

Despite one of the wettest seasons we’ve seen in years, we’re proud to share that the Royal Mews Retaining Wall is now complete! 🌧️➡️☀️

Excessive rainfall meant delays, but for us, quality comes first. We made sure the base was dry, stable, and solid before building upward—because a retaining wall is only as strong as the foundation it rests on.

Built with Allan Block and a Drain Pro drainage system, this wall is designed to withstand the elements, endure over time, and stand strong for years to come.

Phase 2 is just around the corner—stay tuned for the next stage of this project!

🚜 Septic System Design & Installation for Acreages – Done Right by a Local Team

Hi there! We’re Kostr Contracting — a small, owner-operated company that specializes in private septic systems for acreages and rural homes.

We know that building or upgrading a septic system isn’t something most people look forward to, but it is something you want done properly, efficiently, and by someone who stands behind their work. That’s where we come in.

We handle everything from design to installation, including permit coordination and inspection support. Whether you’re building a new home or replacing an older system, we’ll help you choose the right type of system for your land and your budget.

What We Offer:
✔️ Personal service — you deal directly with the owner
✔️ Custom septic system design for your property
✔️ Tank & field installation (including at-grade & mound systems)
✔️ Permitting and code compliance handled
✔️ Honest pricing and no sales pressure
✔️ Clean, respectful work on your land

We’re based out of Calgary and work throughout Southern Alberta, within about 2-3 hours of Calgary city limits.

If you’re looking for straightforward advice, solid workmanship, and a crew that treats your property like their own — give us a shout.

Started a new project today with and .management right in the heart of downtown Calgary — next to the iconic Simmons building.

Tight spaces like this require careful planning, sharp communication, and experienced operators to get the job done right.

Let’s get to work. 💪🦺

💥 Project Kickoff! 💥
We’re back at it again with Russpet Construction, this time replacing an old tiered wood retaining wall with a brand new tiered Belgard Allan Block retaining wall. It’s going to bring a fresh look and will provide long-lasting strength and durability to this gorgeous multi-family property In Royal Oak!

Now we just need the weather to start cooperating! 🌧️➡️☀️

Teamwork Makes the Dream Work! 🚜🏗️

Kostr Contracting was on-site at Impeccable Interiors’ commercial building in the brand-new Homestead community in NE Calgary, getting our hands dirty (literally) to help keep the project moving!

From backfilling trenches to exposing sanitary and stormwater lines for building tie-ins, we’re making sure this site is prepped and ready for what’s next. Big things are happening, and we’re pumped to be part of the process!

Shoutout to Impeccable Interiors for trusting us with the heavy lifting! 💪🏼 Stay tuned—Homestead is shaping up to be something special!
