How long does a septic inspection take?

Most take one to three hours. Time depends on how easy the system is to find, whether the tank is pumped during the visit and how much testing is done on the drain field.

Is a home inspection enough for a septic system?

Usually not. General home inspectors often do only a quick look at the septic system. A septic company opens the tank and evaluates the drain field, which gives a much more complete picture.

Who pays for a septic inspection during a sale?

It depends on your contract and local practice. Buyers often pay for their own inspection, while some sellers order one before listing. Your real estate agent can tell you what is typical in Montesano.

How often should I inspect my septic system?

A professional inspection every few years is a good habit, often at the same time as pumping. Systems with pumps, aerobic units or known problems may need more frequent checks.

Septic System Inspections for Montesano Homes

A septic inspection tells you whether the system under a Montesano property is working, what shape the tank and drain field are in, and what repairs might be coming. It is one of the most useful reports you can have before buying or selling a home that is not on city sewer.

Request a call and a septic company that inspects systems in Montesano and Elma, Cosmopolis, Aberdeen will explain what their inspection includes and when they can get out.

Inside a full septic inspection

A full inspection looks at the whole system, not just the tank. The inspector finds the tank and field, reviews any permits or past reports, opens the tank, and checks the liquid level, scum and sludge layers, baffles and filter. They then look at the distribution box, pumps and alarms if present, and the drain field area.

Quick checks versus complete inspections

Some inspections only confirm that drains run and nothing is obviously wrong. A complete inspection opens and measures the tank, examines the baffles and filter, checks pumps and alarms, and evaluates the drain field. When money is on the line, such as a home purchase, the complete version is usually worth it.

Inspections for buyers and sellers

Buyers use an inspection to learn what they are taking on. Sellers use one to fix problems before listing or to show buyers the system is sound. In either case, schedule early in the process so there is time to pump, make repairs or negotiate. Waiting until the last week before closing leaves little room if the inspector finds a problem.

What you get in the report

A good inspection report lists the tank size and material, the liquid level and the sludge depth. It covers the baffles, lid and any filter, how the drain field looked, and anything that could not be reached. It should say clearly whether the system was working at the time of inspection and list recommended repairs or maintenance. Photos are a plus. Keep the report with your home records.

Getting ready for the inspector

Find any septic permit, the original design drawing and receipts from past pumping or repairs. If you know where the tank lids are, clear grass, mulch or snow from them. Let the inspector know about any past backups or wet spots, and plan for normal water use in the house beforehand.

What to ask when you book an inspection

Ask exactly what the inspection includes, whether the tank will be opened and pumped, and whether the drain field will be tested. Ask about their experience with your type of system, how long the report takes, and whether the report format is accepted by lenders in Grays Harbor County.

What inspectors look at closely around Montesano

Because most mapped soils near Montesano are rated very limited for septic absorption, inspectors pay special attention to how the drain field is handling water.

The most common drainage class is well drained.
