DUNWOODY REPLACEMENT REVIEWS

★★★★★
“Septic Rooter was amazing! My field drain had been severed by a retaining wall and I had gotten a previous diagnosis of a new field drain which was going to cost me $10k! I found Septic Rooter and called on a Friday afternoon. The owner answered the call and had guys out the next morning.”

“After several unrealistic quotes, he fixed the problem with our septic tank and for a reasonable price. No more problems.”

★★★★★
“Found these guys after being upsold by a previous septic company and they were first class. Actively turned down work as told me it wasn't required and would be a waste of money.”

★★★★★
“Everyone that I had the pleasure to speak with and/or meet with were totally professional. From the first email and phone call with Beth, to the consultation meeting with Rob, and the install by Scott and Martin, the experience was exceptional.”

The Dunwoody Septic Health Checklist

8 things every Dunwoody homeowner should know

🚿 Pump every 3–5 years

Regular pumping removes solids before they reach your drain field — most homes need service every 3 to 5 years.

🚫 Never flush wipes or grease

“Flushable” wipes don't break down and grease coats your tank — both accelerate failure fast.

💧 Spread out water usage

Back-to-back showers, laundry, and dishwasher cycles can overwhelm the system. Space them out.

🌿 Keep roots away

Tree and shrub roots seek out moisture and invade tanks and lines — a leading cause of repairs.

🚗 Keep traffic off the field

Don't park or drive over the drain field — compaction crushes lines and ruins percolation.

👁 Watch for early signs

Slow drains, odors, or lush green patches in the yard are early warnings — don't ignore them.

📋 Keep your records

Save pumping and repair records — they help at resale and speed up any future diagnosis.

📞 Call at the first symptom

Catching problems early in Dunwoody almost always means a cheaper, simpler fix.

Common Questions

Septic Replacement FAQ — Dunwoody

How much does it cost to replace a septic system in Dunwoody?
A full septic system replacement in Dunwoody — including the drain field — typically runs $16,000–$45,000. A tank-only replacement, when your drain field is still good, is less: $6,000–$9,500. Georgia's heavy clay and site-specific soil conditions are the biggest cost drivers. We give a fully itemized quote in Dunwoody before any excavation.
How much does it cost to replace a drain field in Dunwoody, DeKalb County?
Drain field replacement in Dunwoody generally runs $10,000–$25,000, depending on system size, soil conditions, and site access. A localized drain field repair, when the failure is isolated, can be much less — around $2,500–$6,500. We evaluate the field before recommending full replacement so you don't overspend.
How long does a septic system or drain field last?
A well-maintained concrete septic tank lasts 25–40 years, and a conventional drain field typically lasts 20–30 years with proper care — pumping every 3–5 years and keeping traffic off the field. Most premature failures in Dunwoody happen at 8–12 years and trace back to a neglected tank.
How long does a septic replacement take in Dunwoody?
Most residential replacements in Dunwoody take 1 to 3 days of on-site work once permits are issued, though the full timeline depends on county permitting and the required pre-construction and final inspections. We handle the permits and scheduling with the DeKalb County health department for you.
Do you guarantee the county inspection will pass in Dunwoody?
Yes. We handle permits, engineering, and inspections in-house and guarantee your Dunwoody replacement passes the DeKalb County county inspection on the first try — no re-dig or re-inspection fees passed to you.
What's the difference between a conventional and an alternative septic system?
A conventional system uses a tank and gravity-fed drain field and works where soil percolates well. When Dunwoody soil, lot size, or a high water table won't support that, an alternative system — such as an Eljen GSF, aerobic, drip, or mound system — is engineered to treat effluent in difficult conditions. Alternative systems cost more (roughly $30,000–$60,000) but make otherwise-unbuildable lots work.
How much does it cost to pump a septic tank in Dunwoody?
In Dunwoody, a standard 1,000-gallon septic tank pump-out typically runs $650–$900. Price depends on tank size, how long since the last service, depth and accessibility of the lids, and whether an effluent filter needs cleaning. SepticRooter™ gives you a firm price up front in Dunwoody before any work — call (678) 744-7878.
How often should I pump my septic tank in Dunwoody?
The Georgia Department of Public Health recommends pumping every 3 to 5 years for a typical four-person household. Larger families, homes with a garbage disposal, or properties that host frequent guests should pump every 2 to 3 years. Regular pumping in Dunwoody is the single best way to avoid a $10,000–$25,000 drain field replacement.
Do I need a permit for septic work in Dunwoody, DeKalb County?
Yes. In Georgia, any septic installation, modification, or repair requires a permit from your county health department (the DeKalb County Environmental Health office), and the work must be done by a DPH-certified contractor. SepticRooter™ is licensed and handles Dunwoody permits and the required inspections for you.
How do I know if my home in Dunwoody is on septic or city sewer?
If you receive a monthly sewer bill from a utility, you're on city sewer. If you don't — and especially if your Dunwoody home is older or outside a dense municipal area — you're likely on septic. You can confirm by checking for a tank lid or cleanout in the yard, or by pulling your system records from the DeKalb County health department, which we can do for you.
Are you licensed and insured to work in Dunwoody?
Yes. SepticRooter™ is a fully licensed and insured Georgia septic contractor, BBB A+ accredited since 1989, NAWT-certified, and Eljen GSF certified. We serve Dunwoody and the surrounding DeKalb County area with same-day emergency response.

DeKalb County Permits & Soil

SEPTIC PERMITS & SOIL
IN DEKALB COUNTY

Septic work in Dunwoody runs through DeKalb County's health department, and local soil decides what's possible. Here's what that means for your property — and how we handle it.

🏛️

Permits Are Required

In Georgia, septic work is governed by the Department of Public Health under Rule 511-3-1, and DeKalb Public Health (Septic System Program) handles permitting and inspections locally. DeKalb's Septic System Program reviews plans, analyzes soil reports, conducts site evaluations, and issues permits for new and repaired systems.

🧪

Soil Drives the Design

Many DeKalb homes near Decatur, Dunwoody, and Stone Mountain are older, on in-town lots where the original system predates current standards — so siting and records often need extra attention. New systems require a Level 3 soil report from a state-certified soil classifier — the old “perc test” is no longer used.

📏

Setbacks & Lot Size

State rules require a drain field to sit at least 100 feet from a well and the lot to be properly sized for both the system and a replacement area. We design every Dunwoody job to pass county review.

✅

We Handle the Paperwork

We're a state-certified Georgia contractor and pull the permits, schedule the DeKalb County inspections, and stand behind the work — so you don't have to navigate the county process yourself.
