"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"

"I have a 1906 cottage in N Seattle, with an old porous foundation. Water came into the basement for the first time in 20 years. Another contractor bid the job at $12,000 after 3 site visits and almost a month. Andy came out to the house the same day I talked to him, and estimated the same job at half that price. He followed up with questions, asked about making another visit, came out again and saw that the drainpipe was disconnected at the top of the area being flooded. 75% of the roof's water was pooling against the house. He found a ladder and fixed it and isn't charging me a dime. So, no French drain, no Delta drain, no foundation treatment, no 50' of trenching, no $$$. Andy was timely, reliable, did what he said, and knows his stuff. He was a great communicator, and I feel so so lucky to have found him."

"Very well. Rome was very knowledgeable and experienced at the work. I believe helped to train me about my concrete needs and make good decisions on our needs. His work schedule is short. They started work the next week. They showed up on time and finished my driveway prep-and pour in less than 2 days. The crew is friendly and efficient. They put the removed driveway gravel on other low spots of our approach road with no extra charge. They only do work directly for customers so maintain schedule flexibility by not being a subcontractor. I recommend them and would rehire them. L. Stine"

"Island Concrete LLC installed a concrete driveway for me quickly (one day) and at an affordable price. The owner, Island, was present from start to finish to supervise and take part in the job. This was very reassuring."

"Excellent company! These guys did a great job of installing insulation in my attic as well as the removal of old insulation. Also, the clean-up job after the job was great too. The technicians were knowledgeable and friendly. No issue in recommending."

"Had a great experience with WA Evergreen Insulation from start to end. Rob came to my house, quoted me an insulation install, made absolutely sure that they would not cover any existing knob and tube with insulation and prevent a fire. The crew showed up and completed the job in one day. Once they got started it was clear they knew exactly what they were doing - and they managed to shimmy into the extremely small attic access and cleaned up my rat jerky in the crawlspace! I'm very happy with this job and with this company!"

Foundation Drain Installation FAQs, answered by experts

Yes, professionals ensure proper grading and drainage to prevent water pooling.

Test regularly, clean the pump, and inspect the discharge line to ensure efficient operation.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

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.
