Drainage Fixes Inside and Out
Outside work usually comes first. Gutters should be clear and sized for the roof, and each downspout should let water out several feet away, on ground falling away from the house. Many Pittsburgh neighborhoods are steeply sloped (the city has about 800 sets of public steps), so a hillside house often catches runoff from above. A shallow swale uphill can turn it aside.
A French drain is a gravel trench with perforated pipe that intercepts yard water and carries it lower, so it needs open ground and a downhill outlet. Interior drain tile works from inside, collecting seepage at the base of the wall and leading it to a sump pit for pumping outdoors. It suits older stone and block foundations, and tight or steep lots where outside digging is hard.
Where water ends up matters as much as how it is caught. Most suburbs bar downspouts and sump pumps from the sanitary sewer. Inside the City, a home can't be sold without an Evidence of Compliance Certificate from the Pittsburgh Water and Sewer Authority's dye-test program, and gutters, driveway drains and yard drains tied to a sanitary line must be corrected first; combined-sewer areas are exempt (Dye Testing Team, 412-255-2443).
Pittsburgh Water's stormwater fee follows a property's hard surfaces. Owners who hold water on site with a rain garden or underground system may earn a lower fee, a rain barrel holding at least 50 gallons earns a one-time $40 credit, and income-qualified customers can cut the fee 85% through PGH2O Cares (412-255-2457). The credits are the authority's own, not this site's; ask Pittsburgh Water what qualifies.
Sewer water is a separate matter. About 75% of the City's system is combined, and the owner is responsible for the entire sewer lateral; Pittsburgh Water maintains the main and the joint called the wye. A backwater valve or lateral repair is plumbing for a licensed master plumber with an Allegheny County plumbing permit. For a City backup, Pittsburgh Water's line is 412-255-2423 (press 1), 24/7.
What Gets Done
- Overflowing gutters. Clearing, enlarging or re-pitching gutters that spill during a downpour.
- Downspouts at the wall. Extensions or new outlets that land roof water well away from the foundation.
- Runoff from uphill. A swale or yard drain that turns water coming down the slope.
- Seepage at the floor's edge. Interior drain tile on the wet walls, feeding a sump.
- A soggy strip of yard. A French drain, where the lot has room and a lower spot.
Price Ranges With Sources
| Cost row | Figure | Source (year) |
|---|---|---|
| Typical basement waterproofing project | about $3,000 to $10,000 (average about $5,000) | Fixr national (2026) |
| Interior perimeter drain, per linear foot | $40 to $120 | Fixr national (2026) |
| Sump pump installation | $600 to $2,500 | Fixr national (2026) |
| Epoxy crack injection, per crack | $250 to $1,000 | Fixr national (2026) |
| Waterproof paint or sealant, per sq ft | $1 to $8 | Fixr national (2026) |
The rows are national; no Pittsburgh-specific source exists. Drain tile is charged by the foot, so one wall and a full loop differ widely, and gutter or grading work is priced per job. Steep lots add labor for access and hauling. Backwater valves and laterals are plumbing, priced by a licensed master plumber. See the cost guide or run the cost calculator.
What to Expect, Step by Step
- Watch a storm. Note where water pools outside, where it appears downstairs and which wall faces uphill.
- The contractor's visit. Roof edges, downspout outlets and the grade usually get checked before the floor.
- Footage on paper. The estimate lists walls covered, total feet and where water leaves the lot.
- Permits. In the City, foundation, excavation and retaining-wall work generally needs a PLI permit, and a steep or landslide-prone lot may also need geotechnical review; the contractor confirms permits with PLI. Plumbing goes to a licensed master plumber with a County permit, and 811 is called before digging.
- The next downpour. That is the real test.
What You Get by Asking Here
Water often has more than one way in, so it helps when one independent local contractor sees the roof line, yard and floor in a single visit. The request is free and earns you nothing; contractors may pay this site to advertise. This site digs no trenches, and it holds no Pennsylvania home improvement contractor registration.
Pennsylvania requires a signed contract for home improvement over $500. Yours should show the contractor's "PA" registration number, drain route and footage, each outlet, dates, total price and your right to cancel. Verify the number with the Attorney General's lookup or 1-888-520-6680, and ask for proof of liability insurance and workers' comp.
Quick Answers
Should gutters and grading come before drain tile?
Often, yes. Outside fixes usually cost less and keep water off the wall to begin with. Should water still reach the floor after that, ask a contractor whether interior drain tile fits and along which walls, since footage drives the price.
Can my downspouts stay tied into the sewer?
That depends on your address and the authority, not the contractor. In the City, Pittsburgh Water's dye test at sale flags gutters and drains tied to a sanitary line, outside combined-sewer areas. Most suburbs bar downspouts from the sanitary sewer and test at sale too. Changing a buried connection is plumbing for a licensed master plumber.
Services That Often Go Together
Drain tile needs a pit at its end, which is where sump pump installation comes in; for a single damp patch, look at basement leak repair or foundation crack repair, and for the whole basement, full basement waterproofing.
