Your home inspector won't check the sewer line. We will — $299 flat rate, same-day scheduling throughout Pierce County. Know what you're inheriting before you close.
ASHI (American Society of Home Inspectors) and InterNACHI standards explicitly exclude underground sewer pipes from a standard home inspection. Even the most thorough inspector will test your drains for slow drainage — but won't tell you whether the pipe itself is made of deteriorating Orangeburg, cracked clay tile, or is full of root intrusion. That information only comes from a camera scope.
Tacoma and Pierce County have some of the oldest housing stock in Washington State. A significant portion of homes were built between 1940 and 1980 — the era of clay tile and Orangeburg sewer laterals, both of which are now at or well past their expected service life.
Orangeburg pipe is a compressed tar-paper material used from the 1940s through the early 1970s. It absorbs moisture over time, loses its round shape, and eventually collapses. No amount of cleaning restores a deformed Orangeburg line — replacement is the only fix, running $8,000–$20,000 or more in the Tacoma market.
Clay tile pipe — the other dominant material in Tacoma's older neighborhoods — develops open joints as the ground shifts. Those joints are an open door for tree roots. Pierce County's most common large trees — Big Leaf Maple, Black Cottonwood, weeping willow — aggressively follow moisture into hairline cracks, eventually filling the pipe with root mass that no home inspection surface test would catch.
Neighborhoods with the highest concentration of pre-1970 pipe include South Tacoma, Hilltop, Lincoln District, Proctor, North End, and most of central Lakewood. If you're buying in any of these areas and skipping the sewer scope, you're inheriting whatever is inside that pipe — sight unseen.
A sewer scope from D Street Drains is $299 + tax. Sewer line replacement in Pierce County starts around $8,000 and can reach $20,000+ depending on depth, pipe material, and access. The math makes this one of the most cost-effective inspections you can add to your due diligence.
Home inspection add-ons are convenient — but they come with a significant limitation.
If the camera finds root intrusion or grease buildup, D Street can often perform hydro jetting in the same visit. A home inspector can only report the problem — we can fix it. You leave with a clean pipe and camera footage showing the before-and-after state.
We provide a verbal findings summary on-site and can supply a camera recording and written note of conditions for your real estate agent. This gives you documentation for repair negotiations, seller credit requests, or contractor quotes — not just a checkbox on an inspection form.
Washington State inspection contingencies typically run 10 days. We offer same-day and next-day scheduling, can coordinate with your buyer's agent, and are comfortable speaking with realtors about findings by phone. Call us when your offer is accepted — not after contingency expires.
D Street Drain Cleaning is a locally owned Pierce County company. We know which Tacoma neighborhoods have the highest prevalence of Orangeburg pipe, where clay tile joint failures are most common, and which tree species create the worst root intrusion. You get a straight assessment, not a scripted upsell.
The camera runs from your sewer cleanout toward the city main, capturing live footage of the entire pipe interior. In Pierce County's older housing stock, we commonly find:
Hair roots to full root mass blocking flow. Big Leaf Maple and Black Cottonwood are the most aggressive species in Pierce County. Root intrusion ranges from early-stage (jettable) to severe (line needs replacement). The camera tells you exactly where you fall on that spectrum.
Orangeburg (used 1940s–1970s) absorbs moisture and loses its round shape over time. The camera shows whether the pipe walls are still firm or have softened and begun to collapse. Deformed Orangeburg is non-negotiable — it needs replacement, and knowing this before closing changes the entire negotiation.
A belly is a low point where the pipe sags — typically from ground settlement or improper original installation. Solids collect in the belly rather than flowing to the main, causing recurring backups. A belly visible on camera is a structural defect, not a maintenance issue. It usually means the affected section needs to be re-graded or replaced.
Clay tile is laid in short sections. Ground movement can pull joints apart, creating gaps where roots enter and solids catch. The camera shows how far separated a joint is and whether it's actively collecting root growth. Cracked pipe sections from ground movement or vehicle loading are also visible.
Years of accumulated grease and mineral scale can significantly reduce the effective diameter of a pipe — even in PVC lines. This is fixable with hydro jetting. Finding it during due diligence rather than after your first major backup is the point.
Designed to fit within your 10-day inspection contingency without adding stress to the transaction.
Don't wait until day 8 of your contingency. Call (206) 948-0851 as soon as your offer is accepted. We offer same-day and next-day scheduling throughout Pierce County. We can often run the scope during or right after your general home inspection.
We locate the sewer cleanout — typically at ground level near the foundation, in the basement, or in the crawlspace. For homes without an accessible cleanout, the camera is sometimes inserted through a toilet or floor drain. The waterproof camera runs from the cleanout toward the city main, transmitting live footage to a monitor. The whole run typically takes 45–90 minutes.
We walk you through what the camera shows, in plain language. If the line is clean, you close with confidence. If there's root intrusion we can clear, we can jet it the same day and run the camera again so you have a clean-pipe recording. If we find a structural defect (belly, deformed Orangeburg, collapsed section), we'll tell you exactly what you're looking at and give you a repair context estimate for your real estate agent.
Minor findings (manageable buildup, early root intrusion) — proceed with confidence knowing the condition. Moderate findings — request a seller credit to cover cleaning or near-term maintenance. Serious findings (collapsed pipe, deformed Orangeburg, severe belly) — request the seller repair before close, negotiate a substantial price reduction, or walk away with full information. We can supply camera footage and a written condition note for your real estate agent or attorney.
D Street Drains charges a flat rate of $299 + tax for a standard residential sewer scope throughout Pierce County. No dispatch fee. No extra charge for same-day scheduling. No surprise add-ons at the door.
Nationally, pre-purchase sewer scopes run $100–$500 depending on provider and market. In Tacoma and Pierce County, professional drain companies and inspection add-ons typically price residential scopes between $200 and $450. Our flat rate includes a verbal findings summary on-site, and camera recording is available on request — both useful for real estate negotiations.
If root intrusion or grease buildup is found and you want it cleared, hydro jetting can often be performed the same day. The scope + jet combination gives you a clean pipe, before-and-after camera footage, and the ability to close without a pending repair condition hanging over the transaction. Call (206) 948-0851 to discuss pricing for your specific property.

Not every Pierce County home carries the same sewer risk. The key variables are the age of the home, the original pipe material, and the tree coverage in the yard. Here's a practical breakdown:
South Tacoma, Hilltop, Lincoln District, North End, Proctor, Central Tacoma. Orangeburg and clay tile predominate. Root intrusion and pipe deterioration are common findings. Sewer scope is strongly recommended.
Lakewood, University Place, older Puyallup, East Tacoma, Spanaway. Transition era — may have clay, early PVC, or cast iron. Root intrusion still possible near mature trees. Scope recommended for homes with significant tree coverage.
Newer construction in Gig Harbor, newer Puyallup subdivisions, newer Lakewood. Typically PVC pipe. Still worth scoping if mature trees are near the sewer easement — PVC is more resilient but not immune to root intrusion at joints.
Regardless of the home's age, if there are large mature trees — especially Big Leaf Maple, Black Cottonwood, or weeping willow — within 20 feet of the sewer line path, we recommend a scope. Root intrusion is the most common finding in every era of housing, and it's entirely invisible until you run a camera.

Yes — especially in Tacoma and Pierce County, where a large share of homes were built with clay tile or Orangeburg sewer lines that are now at or past their service life. ASHI and InterNACHI standards explicitly exclude underground sewer pipes from a standard home inspection. A scope before closing is the only reliable way to know what you're inheriting — and sewer line replacement runs $8,000–$20,000 or more. A $299 scope is cheap due diligence.
D Street Drains charges $299 + tax for a standard residential sewer scope throughout Pierce County — flat rate, no dispatch fee, no extra charge for same-day. Camera recording is available on request. Call (206) 948-0851 to schedule.
Most residential scopes take 45 minutes to 1.5 hours. We can schedule during or immediately after your general home inspection window and we offer same-day scheduling — call by noon and we'll typically confirm that day. We're comfortable coordinating with your real estate agent and can discuss findings by phone.
You have options. Minor findings (grease buildup, early root intrusion) — D Street can clean it the same day and run the camera again so you close with a clean pipe. Moderate findings — use for a seller credit or price negotiation. Serious findings (deformed Orangeburg, major belly, collapsed section) — request that the seller repair before close, negotiate a substantial credit, or walk away with full information. We can supply camera footage and a written condition note for your agent.
Some inspection companies offer sewer scope as an add-on — but they can only report findings. They cannot clean, jet, or repair the line. D Street can scope the pipe and, if root intrusion or grease buildup is found, perform hydro jetting in the same visit. You leave with a clean pipe and before-and-after footage rather than a report with a repair referral and another scheduling gap.
Orangeburg pipe (used 1940s–early 1970s) that has softened and deformed; clay tile with open joints that attract tree root intrusion from Big Leaf Maple, Black Cottonwood, and willow; pipe belly from ground settlement; and joint separation. None of these are visible during a standard home inspection. Highest-risk neighborhoods: South Tacoma, Hilltop, Lincoln District, Proctor, North End, and central Lakewood.
Washington State purchase agreements typically include a 10-day inspection contingency. Call D Street Drains at (206) 948-0851 as soon as your offer is accepted — don't wait.
