"From consultation to completion the team at Groundworks handled our foundation repair with care and professionalism. Matthew came to the house and stayed to answer every question and explain every detail. He took the time to complete a bid while onsite and walk us through the process. (BTW their permitting department and financing through GreenSky really helped!) When the work started the first team of Alex, Iuni and Luis, were exceptional (they pier leveled the footing). We got texts the moment they arrived at the property and they got right to work, completing their part right on time. They worked as quietly as possible and kept us informed of the progress. The second team for foam leveling our slab and led by Daniel, got it all done in part of a day. They were also courteous and even helped move furniture. When the work of both teams was finished Alex, the foreman, walked us through an inspection and answered all our questions. Finally, Matthew circled back at the end and made sure"

Customers say: Quality work

"Rick listened very carefully to what we wanted for our project. He is an exceptionally hard worker. Two contractors who came to our home since the completion of the concrete slab by Fischer Concrete noticed the quality of the work and asked us who poured the slab. We are totally satisfied with Fischer Concrete."

"Elias Contruction provided a detailed estimate after inspecting the roof and making some qualified recommendations. The project required a few change orders that were not clarified in writing. I would recommend hiring Elias if you get changes in writing. They cleaned up pretty well although they missed a few things due to finishing in the dark. Overall satisfied with the job and cost was 60% of other bids due to sheathing adjustment."

"As usual, they did an outstanding job. This is the fourth time I've used Rain Pros services (drain tile installation, addition of topsoil to roll and level lawn, over seed existing lawn). Their crew is hardworking, prompt and professional. They are very knowledgeable and skilled. I have never been disappointed."

"We've had a handful of unsatisfying contractor experiences, so we tend to be a bit skeptical but our experience with Terra Firma set a new bar for us. Highly professional from start to finish. Initial consult was thorough, and didn't add on anything we didn't ask for or need. When they were working at the house the crew was prompt, professional, left the jobsite clean each day. Final result was exactly what we were expecting. Worth the investment, don't go with the lowest bidder on your foundation, it's not worth it. Thank you Terra Firma crew!"

"WOW!! Can't say enough on how pleased we are with Ray. Our three household pump went out the night before New Years eve. Called Mountain Pumps and Plumbing in the morning. Ray came out within minutes, check out the system and found our submersible pump was out. While he pulled the pump (110 ft deep) he sent a driver Port Orchard for a new pump. By 4:00 PM we once again had much appreciated water."

Foundation Drain Installation FAQs, answered by experts

Your sump pump will discharge water through a discharge line or pipe. The discharge line should be placed at least 10–20 feet from the foundation to avoid any issues.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

There are a few possible sump pump drainage locations, including a neighborhood storm drain, into a creek or pond, or underground. Don’t let your sump pump water go into your sewer or septic system. Ideally, your drainage spot should be on a downhill slope that’s at least 10 to 20 feet away from your home’s foundation. Before choosing a location, check your local codes and regulations.

The difference between an ejector pump and a sump pump lies in their purpose and design—an ejector pump functions to remove liquid gray water and soft solid sewage waste from your home. If you have a laundry room or bathroom in your basement, an ejector pump for your sewage tank prevents sewage from backing up in your washing machine or bathroom’s drains.

A sump pump is designed to remove excess groundwater that may enter your home, either due to flooding or periods of heavy rain.

The cost of installing landscape drainage with the help of a professional can vary widely depending on factors like the scope of the project, your location, and the specific services needed. Smaller tasks, such as installing a French drain, may range from $10 to $50 per linear foot, while more extensive projects like installing a catch basin can cost several thousand dollars to tens of thousands. Obtaining multiple quotes from qualified professionals is recommended to get a precise estimate for your specific drainage issue.
