Water finding its way into your home from outside right now? Call now for 24/7 emergency service — see the number above for immediate help.
Who you call depends entirely on where the water is actually coming from. A plumber handles burst pipes and plumbing-related leaks; a roofing contractor handles roof and gutter failures; a waterproofer handles foundation cracks and drainage problems; and a water restoration contractor handles the cleanup once standing water, dampness, or mold is already present. Many cases genuinely need more than one of these, in sequence.
Step 1: Recognize the Problem
Exterior water intrusion has several distinct causes, and the symptoms often point to which one you’re dealing with:
- Cracks or holes in the foundation or basement walls
- Poor grading or drainage directing water toward the house instead of away from it
- Heavy rain overwhelming existing drainage
- Damaged, clogged, or disconnected gutters and downspouts
- A malfunctioning sprinkler system saturating soil near the foundation
- A roof leak allowing water to travel down into walls or ceilings
- A failed sump pump allowing groundwater to back up
Step 2: Decide DIY vs. Professional
A small, one-time seep after an unusually heavy storm might resolve on its own once the ground dries. But recurring leaks, visible cracks, standing water, or any sign of mold are not DIY territory — misdiagnosing the source or delaying repair typically makes the eventual fix more expensive, and standing water creates real health and structural risk the longer it sits.
One thing you can check yourself before calling anyone: whether the ground around your foundation slopes away from the house. Most building codes require the grade to fall at least 6 inches over the first 10 feet away from the foundation — if your yard slopes toward the house instead, that alone can be feeding water into your basement regardless of what else is going on.
Step 3: Know Exactly Who to Call, and Why
Plumber — For Burst Pipes and Plumbing-Related Leaks
If the water traces back to a plumbing issue — a burst pipe, a failed connection, or a fixture leak that has spread outward — an emergency plumber is the right call. Shut off the water supply to that section if you can identify it, which limits damage while you wait. Emergency plumbers work on a 24/7 basis specifically because plumbing failures don’t wait for business hours, and prompt response limits both water waste and the extent of damage.
Roofing Contractor — For Roof and Gutter Failures
If water is entering through the roof — often after storm damage, or simply from a roof reaching the end of its service life — a roofing contractor is the right call. They can identify the specific failure point and repair it before more water gets in.
Waterproofer — For Foundation Cracks and Drainage Problems
A waterproofer specializes in fixing cracks in foundations and basement floors, sump pump issues, and window leaks at grade level. If your symptoms point to water coming up through the floor or seeping through basement walls rather than dripping from above, this is the specialist to call.
Water Restoration Contractor — For Cleanup After the Source Is Fixed
Once the source of the leak is addressed, a water restoration contractor handles what’s left: standing water, damp walls, musty odors, and any visible mold. They bring equipment — air movers, dehumidifiers, moisture meters — that goes well beyond what a homeowner can rent or borrow, and their job is specifically to dry the space thoroughly enough to prevent mold from taking hold.
If your situation has already progressed to standing water, damp walls, or visible mold, our water damage restoration team handles assessment and full remediation.
If the water is coming up through your foundation or slab rather than from above, see our slab leak repair page for how that specific cause is diagnosed and fixed.
How Fast Can Help Arrive?
Plumbers handling active leaks typically treat the call as an emergency and can respond same-day, often within hours. Roofing contractors and waterproofers usually work on a scheduled basis unless the situation is actively worsening, though many will prioritize an active leak over routine work. Water restoration companies generally aim for rapid response too, since the 24–48 hour window before mold risk increases is a real deadline, not just a suggestion.
Why Trust the Recommendation
Before hiring anyone for a water intrusion issue, it’s worth confirming a few things regardless of which specialist you need: current licensing and insurance, a track record of similar jobs, realistic (not exaggerated) guarantees, and genuine 24/7 availability if your situation is urgent. A company that has handled this type of problem for years will typically diagnose it faster and avoid the trial-and-error a newer or unlicensed operation might fall into.
Frequently Asked Questions
How do I know if I need a plumber or a waterproofer?
If the water traces back to a pipe, fixture, or supply line, call a plumber. If it’s coming through a foundation crack, basement floor, or window at grade level with no plumbing involved, a waterproofer is the better fit. When you’re not sure, a plumber can often help rule their side out quickly.
Can poor yard grading really cause water to leak into my house?
Yes. Most building codes require the ground to slope away from the foundation at least 6 inches over the first 10 feet. If your yard slopes toward the house instead, rainwater is being directed straight at your foundation regardless of how well-sealed your basement walls are.
Do I need to call multiple professionals for one leak?
Often, yes. It’s common to need the specialist who fixes the actual source (plumber, roofer, or waterproofer) and separately a water restoration contractor to dry out and remediate any resulting damage — these are genuinely different jobs, even for the same underlying leak.
What should I check before hiring a water damage professional?
Confirm current licensing and insurance, ask about experience with similar jobs, be wary of guarantees that sound too absolute (like promising mold will never return), and confirm real emergency availability if your situation is urgent.
Is a one-time leak after heavy rain something to worry about?
A single, minor seep that clears up once the ground dries may not need a professional. But if it recurs, if you see standing water, cracks, or mold, or if it happens with rainfall that isn’t unusually heavy, that points to an ongoing problem worth having assessed.
