Residential Construction Contractors in Durango, CO
When you've bought a piece of land near Durango, the first contractor you need works the ground, not the walls. We're residential construction contractors focused on site work: clearing the parcel, grading it, putting the septic and utilities in, and getting everything build-ready so your builder can start framing.
Most local firms market themselves as home builders and say very little about the site-work phase that has to happen first. That's the part we handle, and for a lot of out-of-town buyers, we're the first call after they close on the land.

What residential site work covers
Residential site work is everything that happens to the land before and around the build. That includes:
- Clearing brush and trees
- Grading and excavation
- Foundation and stem wall prep
- Septic system installation
- Underground utilities, including sewer and water lines
- Driveways and access roads
- Demolition
- Retaining walls
- Drainage
Most homeowners don't realize how many moving parts that involves, or how easily things go sideways when each phase is handled by a different crew that doesn't know what the next one needs.
We do it differently. One team handles the full scope under one contract, so you've a single point of accountability from the first cut to the day your builder starts.

Why Durango homeowners and builders trust Animas Excavating
We've been working residential projects in the Durango area since 2018, and we're licensed and insured, fully insured and bonded. We're also a licensed OWTS installer, which is the technical name for a septic system, listed on the La Plata County Public Health roster. That matters for any project that needs a septic system. Our Google rating sits at 5.0 across 24 reviews. What that trust really comes down to is local knowledge. La Plata County ground isn't forgiving, and the permitting here takes someone who knows which office handles what and how to sequence the work so you're not stuck waiting on a fixable problem.
Our experienced Durango construction team is led by founder Mike Zarlingo, who's your first point of contact on any project, and foreman Ben Keil, who runs our crews day to day on site.
One team instead of several contractors
Here’s a situation we hear about more than we’d like. A homeowner hires a separate excavation crew, a separate septic installer, and a separate driveway contractor. The excavation crew grades the site and leaves. The septic installer shows up three weeks later and finds the grade conflicts with where the leach field has to go. Now there’s rework, a gap in the schedule, and a permit hold, because the county inspection can’t move until the conflict is sorted out.
On a steep La Plata County lot, that gets worse. Rocky ground doesn’t always cooperate with the original plan, and when the crew doing the foundation prep doesn’t know what the septic installer intended, you end up disturbing the same ground twice. That’s double the cost and double the delay.
Our model puts one accountable team on the whole scope. We know how the clearing sets up the grading, how the grading affects the foundation prep, and how the foundation prep ties into where the septic field goes. We also stay in touch with your builder through construction so each phase supports the next.
One contract, one point of contact, and one team that sees the whole picture.
Residential site-work services we provide in Durango and La Plata County
As a Durango residential construction company, we cover the full range of residential site work across La Plata County and the surrounding Four Corners region, from a raw parcel to a build-ready site.
Here’s what that looks like in practice.
Residential land clearing
Clearing land in the Durango area is a different job than clearing a flat lot on the Front Range. Most rural parcels here have heavy vegetation, stands of ponderosa or spruce, rock outcroppings, and uneven ground that calls for different equipment and a different approach.
We handle brush removal, tree clearing, stump grinding, and debris hauling, and we plan the clearing around the grading that follows it. Getting that order right from the start keeps the project moving and saves you from paying for rework later.

Excavation and grading
Digging for a new home in La Plata County often means cutting through hard rock, and most hillside lots need cut-and-fill work to sit stable and drain right. We handle both.
What sets our grading apart is the technology. We use 3D smart grade GPS satellite technology that sets the elevations exactly, without the old grade stakes and string line, which makes the work faster and more accurate. On a sloped lot, even a small grading error can send water toward the foundation instead of away from it, so we set every grade thinking about where the water ends up.

Residential foundation and stem wall site work
We do the excavation and site prep for residential foundations, footers, and stem walls. That covers trench excavation, soil compaction, footer prep, and working with your builder on the exact depths, dimensions, and drainage the foundation needs.
To be clear about scope, we don't pour concrete or build the structure. That's your builder's work. Ours is making sure the ground is ready, the dimensions are right, and the drainage is set before the forms go in. Getting the residential foundation and residential stem walls prep right the first time is what keeps the build on schedule.

Residential septic system installation
We're a licensed OWTS installer on the La Plata County Public Health roster, so we can coordinate the permitting and handle the full installation for a residential septic system.
That covers the site evaluation, coordinating the system design with the engineer of record on engineered systems, digging for the tank and leach field, and supporting the county inspections through to closeout. Southwest Colorado's rocky ground and shifting soil conditions make septic work more involved here than in other parts of the state, which is exactly why local experience pays off.

Residential sewer line repair
Residential sewer line repair covers both new construction hookups and existing lines on older properties. Durango's freeze-thaw cycles and rocky soil put real stress on buried lines and limit how those lines can be run.
We find the problem, dig down to the bad section, replace the pipe, and backfill with special flow fills and special backfills. When the work runs out into the street, we take care of the surface restoration too, patching the asphalt, patching the sidewalk, and the curb and gutter. For new construction, we run the sewer line from the house out to the municipal connection.

Residential driveways
A driveway on a mountain or rural parcel in La Plata County is usually more than laying down gravel. Plenty of properties need real cut work before a driveway is even possible, and steep access roads need culverts and erosion control to hold up through the wet seasons.
We prepare the base, grade it for drainage, and put down the surface material. Where the driveway meets a county road, we work with the access requirements so the approach is built to last.

Underground utilities
We put in the water, sewer, storm drain, and power lines that connect a build to city services or to a private well and septic. On new construction, that means running the lines from the house out to the connection point and coordinating with the local utility providers and inspectors along the way.
Demolition
When a project starts with an old house, barn, or garage that has to come down first, we handle the demolition and the haul-off, then move straight into the new site work with the same crew. That keeps the teardown and the rebuild on one schedule, under one contract.
Retaining walls
We build retaining walls in two materials: pre-cast engineered concrete block and natural stone. On the sloped lots that are common around here, a well-built wall is often what makes a building pad, a driveway, or a usable yard possible in the first place.
Building in Durango terrain: what you need to know
A lot of homeowners come to us worried about their lot. Mountain terrain, rocky ground, forested acreage, a long access road. They're not sure the parcel is buildable, or what it'll cost just to find out. Here's what we run into regularly in La Plata County:
- Hard rock close to the surface: It's common across much of this region. When bedrock sits that high, ordinary digging isn't enough, so we bring in hydraulic rock hammers to break through it and haul the material off site. It adds time and cost, but it's a normal part of site work here, not some rare surprise.
- Steep grades: These need cut-and-fill work planned for that specific slope, cutting into the slope and building it back up. We work out the sequence to handle drainage and keep the ground stable before any foundation work starts. Get the grade wrong on a hillside lot and the problems follow you through every phase after.
- Remote access: We haul equipment to sites with limited or unpaved roads and plan the logistics around the weather and road conditions. The season is real here too, with spring through fall being the workable window for higher-elevation and remote properties.
Our team has worked across all of these conditions since 2018, and none of them are a reason to walk away from a property.

Projects Completed What residential site work costs in the Durango area
Price is the question on every homeowner's mind, and it's usually the thing other companies say the least about. We'd rather be straight with you. Building a home in the Durango area runs high, and site work is one piece of that total, so it helps to understand what drives the number before you set your budget.
A few things move it more than anything else:
- Terrain and access. A steep or remote parcel takes more equipment, more time, and more hauling.
- Ground and rock conditions. Hard rock near the surface means hammering and removal.
- Hauling distance for material.
- The foundation type your build calls for.
- The length of the utility and septic runs.
We give free estimates as part of the bidding process. When the scope is clear and straightforward, we bid a fixed cost, so you get a hard number.
When the conditions are less certain, we use a time and materials contract, so you're not paying for padding built into a guess. Either way, you'll know what each part of the job costs and why, with no hidden line items.
Who we work with
We work with three main groups:
- New landowners: Homeowners who've bought, or are about to buy, a raw piece of land in La Plata County and need someone to take them from bare ground to a build-ready site, putting all the infrastructure in. For a lot of them, we're the first call after the purchase, and we'll point you toward the builders and trades you'll need next.
- Builders and general contractors: Custom home builders who want a reliable site-work sub that communicates clearly, hits the schedule, and works in step with their build. We're not a general contractor or home builder ourselves, so we don't compete with the builders we work alongside.
- Existing homeowners: Owners of an existing home who need sewer line repair, a septic replacement, a driveway rebuilt, or utilities upgraded. These projects don't take a full land build-out, but they take the same quality of site work.
A good fit means real site-work scope, owners who value coordination and straight talk, and builders who want one sub handling the ground-up work start to finish.
How a Residential site-work project works with us
You can reach us by phone, text, or email. We start with a short exploration call to understand the project and see if we're the right fit. From there, here's how it goes:
- We get on site promptly: We walk the parcel, look at the access, and talk through the full scope, spotting the terrain challenges, permitting needs, and sequencing decisions before any work starts.
- You get a written estimate: It covers every site-work phase, with each part priced and explained.
- We handle the permitting: We take care of, or actively support, the La Plata County permits for septic, grading, and utility work. On septic projects, we work directly with La Plata County Public Health through the inspection process.
- We do the site work in order: Clearing, excavation, utilities, and foundation prep each happen with the next phase in mind, and we stay in touch with your builder so the work lines up with the build.
- We invoice weekly: At the end of each week, you get an invoice for the work we completed that week, so you always know exactly what you're paying for.
- We finish the grade and clean up: Once the construction support is done, we set the final grade, handle the drainage, and leave the property clean and ready.
Frequently asked questions about residential site work in Durango
What does residential site work cost in the Durango area?
It comes down to the parcel: the terrain, the access, and what’s in the ground. We give free estimates and bid either a fixed cost when the scope is clear or time and materials when the conditions aren’t, so you understand the number before you commit.
Do you work with custom home builders and general contractors?
Yes. We work alongside builders from the first site walk to the final grade, as a site-work sub rather than a general contractor. Builders who hire us get one point of contact for the entire ground-up scope.
How long does residential site work take?
It depends on the scope, the terrain, and how long permitting runs. A straightforward parcel on flat, accessible ground can move quickly. A steep mountain lot with hard rock, septic permitting, and a short access season takes a good deal longer. We give you a realistic schedule in the proposal and we’re upfront about where delays are most likely.
Do you handle La Plata County permitting for septic systems?
Yes. As a licensed OWTS installer on the La Plata County Public Health roster, we coordinate the permitting from the application through inspection and work directly with county staff, so you’re not stuck managing that process yourself.
Can you work on steep or rocky lots in the Durango area?
Yes. Steep grades, rocky ground, and remote access are everyday conditions for us in La Plata County, not reasons to turn a project down.
Serving Durango and surrounding communities in Southwest Colorado
We work across Durango, Bayfield, Hesperus, Mancos, Cortez, and Pagosa Springs, and the broader Four Corners region.
