"We had a tricky leak that needed tracking down. We could hear it, but not see it. Our usual plumber was not available, so found Schmitty's on AngiesList and called. Thankfully, he was available to come out that afternoon, and after some detective work we finally narrowed down the area. It was evening by then, so he brought Trace out first thing in the morning to dig under the foundation and expose the leak. Between the two of them, they solved the issue... which turned out to be not one, but four pinholes in the copper pipe underneath the cement slab foundation. Brian said it might be the trickiest soldering job on the least amount of available pipe (1/4") in a very tight area in 20 years. Their pricing was reasonable and fair for an emergency service. Would definitely call them again. Thanks Schmitty!"

.Job started 3 days late due to delays on a previous job.

Crew arrived on time Monday, 6/29 and installed braces under the foundation on the front, north side of the house and front south side.  re-leveled foundation which had settled slightly over the years.  This was done manually.

Crews also installed pop up drains and conduit to allow water to flow away from the house as it was accumulating in the crawl space, causing some issues.  This was done on all sides of the house and interconnected all of our downspouts.

Finally, underneath the house, crews installed braces to better support interior walls and stabilize the floor, which was flexing somewhat.  While in code, it was annoying and this was taken care of as well as re-leveling the floor in the kitchen and dining areas.  They also installed fresh vapor barrier plastic in the entire crawlspace

This work took one day longer than scheduled, however, despite some additional purchases, there was not additional cost to us.  I am very pleased with the work performed under extreme heat conditions.  I would use Matvey again.

FAQs for sump pump or interior foundation drains installation projects in Black Diamond, WA

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
