Plumber reviews from Delaware homeowners
Sewer backed up into the basement at 11pm on a Saturday. They picked up, showed up in under an hour, and had it cleared and camera-inspected before 1am. Flat price like they said.
Marcus T.Wilmington, DEWater heater died in January. Straightline had a new one installed by 3 the same afternoon and hauled the old one away. Great communication the whole time.
Denise R.Dover, DEThird plumber we called for a slow kitchen drain, first one that actually fixed it. Hydro jetting made a huge difference and they showed us the video.

Questions Delaware homeowners ask
Do you really answer 24/7?
Yes. A dispatcher, not a voicemail, answers (888) 480-9811 around the clock and sends the closest available plumber anywhere in Delaware.
How much does a plumber cost in Delaware?
We quote a flat price before any work begins. Common repairs like a running toilet, a clogged drain or a water heater element are priced from a standard book, and the price you approve is the price you pay.
Which areas do you cover?
All three counties: New Castle, Kent and Sussex. From Wilmington and Newark down through Dover, Milford, Seaford and Georgetown to the beaches at Lewes, Rehoboth, Bethany and Fenwick Island.
Do you do gutters as well as plumbing?
Yes. Gutter cleaning, repair, seamless gutter installation and downspout drainage are part of what we do, because overflowing gutters cause more basement water problems than most people realize.
Is there an extra charge for weekends?
No. Same flat rate, day or night, weekday or weekend.
