Septic work we bid in Evergreen

We visit your site and bid the job. A licensed septic installer does the work and holds the contract and the county permit.

What the ground is like around Evergreen

Mountain lots are the hardest septic jobs near Denver. Bedrock can sit close to the surface, lots are steep, and there is often only one place on the property where a field can legally go.

Shallow soil over rock usually means an engineered system, such as a mound or a treatment unit, instead of a simple gravity field. Tight driveways and trees also limit the size of the equipment that can reach the site. All of that shows up in the price, which is why a mountain job gets a site visit before anyone gives you a number.

How a job goes

  1. Call or text. Tell us the address, the number of bedrooms and what is going on.
  2. Site visit. We look at the lot, the slope, the access and where a tank and field can go.
  3. Written price. You get the price in writing. If you have another written quote for the same job, show it to us and ours will be lower.
  4. Permit and install. A licensed septic installer pulls the county permit, does the work and has it inspected.

Permits in Jefferson and Park counties

Every new or replaced septic system in Colorado needs a permit from the local public health agency, and the system has to be sized from a soil evaluation of your lot. The rules and the fees are set locally and they change, so the permit, soil test and design are quoted for your property instead of guessed at.

Most installs start around $15,000. The final price comes after a site visit, because soil, system type, home size and access set it. The county permit, soil test and design are extra and quoted separately, so your total may vary.

Septic questions from Evergreen

How much does a septic system cost in Evergreen?

Most installs start around $15,000. The final price comes after a site visit, because soil, system type, home size and access set it. The county permit, soil test and design are extra and quoted separately, so your total may vary.

Will you really beat another written quote?

Yes. Bring a written quote from a licensed installer for the same job at the same property, meaning the same system and the same scope of work. After we see the site, we will give you a lower price in writing.

Who does the work?

We visit your site and bid the job. A licensed septic installer does the work, holds the contract with you and pulls the county permit.

There is rock all over my lot. Can a septic system still go in?

Usually, yes, but it may need an engineered design such as a mound or a treatment unit. The soil evaluation shows how deep the usable soil is.

Can you install in the mountains in winter?

Sometimes. Frozen ground, snow and county inspection schedules can all slow a job down. Call and we will tell you what is realistic for your lot.
