Who We Serve

Property owners, custom builders, and developers building from scratch on residential or small commercial sites.

Problems we solve

We prep house sites and small commercial pads from clearing to finish grade, set up so the concrete, framing, and finish trades have a clean foundation to land on.

More Than 70% of Kootenai County Jobs Are Tied to Construction

From custom homes in Hayden Lake to lake cabin tear-downs in Bayview, North Idaho’s growth runs on what happens beneath the slab. Quality has to start from the ground up. We’ve spent 35+ years on civil construction sites making sure what’s underneath supports what’s built on top, residential or commercial.

Most Excavation Calls Sound Like One of These

Most excavation calls fall into one of these situations. If yours does, we’ve handled it before.

You’re Building a Custom Home and Need a Reliable Site Prep Crew

The architect’s done, the plans are stamped, and the build schedule is set. You need a site prep crew that shows up when scheduled, finishes to the standard the next trade can land on, and doesn’t leave your foundation guy waiting on a Monday morning.

You’re Tearing Down an Old Lake Cabin to Build New

Your property has the lake. The 1960s cabin is past saving. You need someone who can demo, haul off, prep the new site, and think through septic location all in one engagement.

You’re a Builder Looking for a Reliable Sub

You need a site prep crew that holds the build schedule, hands off a clean foundation, and communicates when something on the property changes the plan. We’ve worked behind enough builders to know what makes their job easier.

You’re Adding a Shop, Barn, or Outbuilding

You’re done sharing your garage with three projects and a tractor. You’ve got the building plans and the location. You need the pad work, the drainage, and the access road handled right.

You Have a Steep, Tight, or Lakefront Lot

Your lot has a slope, a setback, or a shoreline that calls for specialized equipment and careful access. The tilt rotator on our excavator is built for this kind of terrain.

You’re Planning a Small Commercial Build

A retail pad, contractor yard, or light industrial site that needs proper site prep, utilities, and grading. We bid on small commercial work and hold a public works license for permitted jobs.

We needed a leach field in the middle of the winter 2B Construction came out. They handled all the permits and worked through the snow and cold to get us taken care of so we could have a working septic system. Excellent job and timely repair. Great communication and cleanup afterwards. Highly recommend 2B Construction! Thank you Ron and Tyler!

I was in need of a plugged septic line that was on city right of way. The inspector gave me Ron's phone number. He met with me the next day to see what he was able to do. My situation unfortunately needed to be done asap and I didn't expect him to drop the project he was on. Fast forward to a month later, Ron worked on a private road drainage issue that affected me and others. The problem was quickly found and fixed plus he was able to bring our road up to county standards if not better. I am very impressed and satisfied with his company and would recommend them.

I am validating all of the 5 star reviews about 2 B Construction. I had a failing septic field. Any question I had prior to or during the replacement of the septic field was answered quickly. Very, very professional, courteous, competent and knowledgeable employees. These guys were working in very rainy weather. Some of the dirt turned to mud yet my yard was left very flat with no tire trenches. Very impressive! I would not hesitate for a second to use them again. Thank you Ron and crew.

We had an issue with our main septic line. That was causing the basement to backfill. 2B was incredibly prompt. Fit us in to relieve our family of the stress with incredible work and a fair price. Would recommend for all projects !

There is no way my words can do justice for the sheer amount of gratitude I have for the work these guys did. The job at my house wasn’t easy, I needed to install two septics along with a whole new drain field (and my land is basically sitting on sheer rock) and the path to make it all work was intertwined with water lines and power lines etc. They made it look like cutting butter and they ensured my property was put back better than they found it. I was referred to them initially by the company that cleans my existing septic tanks and I am so thankful for that. Ron, Tyler, Dave and every person that worked on my property treated it as their own, fully explaining everything along the way. Definitely the best guys to have on your job in town, truly great people and I am truly blessed to have found them.

Our drain field failed. We have very limited space on our lot by the lake. 2B worked with the county to make a plan that made replacement possible. They also redid our driveway. Everything came out better than expected. Thanks guys for an excellent job!

2B Construction installed a semi-complex septic system after the current system failed. The installation required a lot of excavation, rock, verti-block, new poly-lines, frost-free faucets, and the installation of several yards of screen drains. They were professional, friendly, prompt, and very skilled. I could not have asked for a better outcome. I can, and have, recommended them with the highest confidence.

I bought a new home with a cracked septic and roots growing into. They reviewed the video I had of my septic and went to town. They were able to squeeze me into their schedule which I was thankful for. Their work turned out wonderful.

Excavation Questions We Hear on Every First Call

How long does a typical site prep take?

Standard residential site prep takes anywhere from a few days to a few weeks depending on lot conditions, scope, and how much utility work is involved. Lakefront and steep lots usually take longer because of access and grading complexity. You’ll get a clear timeline in the written quote.

Do you handle utility trenching as part of the site prep?

Yes. Water, electrical, and sewer trenching for new builds is part of most site prep packages. We coordinate with the builder’s schedule so the trades following us aren’t waiting on open trenches.

Can you handle steep, tight, or lakefront lots?

Yes. Our excavator runs a tilt rotator, which makes precision work possible on steep slopes and tight lakefront properties. We’ve built our residential capability around the lots that need careful access and finish.

What's actually included in a custom home site prep?

A typical custom home site prep includes clearing, foundation excavation, grading and pad prep, utility trenching, and finish grade. We can also coordinate the septic install if it’s part of the project. Specifics vary by lot and build, and we spell everything out in the written quote.

Do you do small commercial site work?

Yes. We hold a public works license and bid on small commercial sites including retail pads, contractor yards, and light industrial builds. Send us your drawings and we’ll put together a quote.

Can you do demolition and haul-off too?

Yes, when it’s part of a larger site prep job. Most of our demo work is lake cabin tear-downs where the property owner is rebuilding new. Standalone demo isn’t a service we run separately.

Got a Build, a Tear-Down, or a Site That Needs Prep?
Let’s Talk.

Tell us what you’re building, where the property is, and the timeline you’re working against. We’ll get back to you within one business day, schedule a site visit if it makes sense, and give you a written quote you can compare against any other bid.
