Constraction reviews in SeaTac, Washington

Groundworks repaired some concrete cracks in our 100-year-old foundation. They also noted our uneven floors and recommended $50K+ helical piles, which we ultimately decided to forego and take a wait-and-see approach (other contractors noted that our foundation settlement was likely due to poor water drainage, which we put money toward instead).

When Ky returned for the 1-year basement checkup, he noted that one of the floor corners had sunk very slightly and once again tried to sell us on the piles. We asked to see the exact measurements, and he never responded to our email. We followed up 3 more times, but received no response.

I've lost some trust in this company; although they were efficient and professional during our initial project, their persistence in pushing an extremely costly intervention came across as dishonest.

Steve came out to measure and create a plan for repairing our foundation. Austin submitted the enginerring for county permits. Cierra coordinated from the office. Tripp, James, and Ryder came out this week to execute the plan and worked for 3 days to lift and stabalize our foundation. They were all respectful and had a positive attitude. Communication was excellent and they made sure we understood the process before the physcal work began. A few changes had to be made but everything was discussed and agreed upon before those were were implemented. We are very happy with the whole team from beginning to end.

Groundworks just installed a perimeter drain with a set of pumps in my crawl space. The entire process from Kristy quoting and managing the installation to Charles and Angel completing the project in 2 days was flawless. They all had great communication and told me exactly what was going on as they did it. I'll have to wait till the next rainy season to see how it works, but I'm pretty confident that they did it correctly.

This is the second time we’ve used Groundwork’s. Jacob, Richard, Timmy and Christian were here for five days water proofing our crawl space that was filled with water and mold. They completely encapsulated it, added a sub pump and an air filter system. They did an incredible job and communicated daily on their progress and findings. The crawl space looks amazing!
I want to give a shoutout to Daniel who showed up on Christmas Eve to inspect it and get us an estimate. Highly recommend Groundwork’s.

Update:
They said my foundation was sinking close to an inch on the right side and quoted nearly $40,000. I took a self aligning leveler and didn’t see 1inch shrinking. Contacted a structural engineer and they didn’t see a problem AND had another professional in my home and they didn’t not see a 1” dip or sinkage. Moral of the story is check around. Just because people are professionals and in the business and can do the work doesn’t mean it is necessary or ordinary. Definitely worth checking around and getting a 2nd and 3rd opinion. 2 stars and not 1 star because they probably can do foundation work but is it ordinary and necessary?

Original post:
Not sure. Looks level to me. Will hire a real structural engineer to verify their accuracy.

Foreman Jacob and associates Charles and Reuben arrived on time and completed the sump pump install in a very timely fashion. Jacob thoroughly explained the complete project and answered all my questions. I would heartedly recommend this crew for drainage jobs. Well done.

Our driveway was so cracked and not level at all…so many places needed repair
Sean checked out all of our cracks and did a thorough inspection. Daniel and his partner were true engineers when it came to repair it all. They were detailed
Great communication with the office when we realized they missed a crack by the step A big project done well!

We were impressed by the initial inspection of the site and video presentation of the solution. An expensive project, complicated…but necessary.
After a scheduling delay, the team of workmen, led by Jacob N. arrived each morning early, and Richard S, Charles U, and Angel F, worked hard all day. They knew their jobs, brought all necessary supplies and made good progress. They worked well as a team.
Jacob was a great communicator and kept us informed of their schedules and their progress.The work site was kept clean and they were all respectful of our privacy and our property. Work was completed in a timely manner. It was a big job! They made us feel comfortable and confident. These were nice young men who knew how to get the job done.
We highly recommend Groundwork’s.

Ricardo S. Ty W. And Michael C. Did a great job. Under the circumstances of this job, Ricardo handled everything professionally, was patient with my elderly parents and ultimately made them both very satisfied with their work. Well done and thanks again!

Very informative. Clear and concise. Gave us many options. Daniel is a wonderful and honest person and was so helpful with our questions. The crew lead by Anthony, with Jordan, Uriel, and Richard did professional work. The finished product is wonderful and can already feel the results in the house. Would 1000% recommend. Just keep in mind it is a very messy job. These guys do the best they can to keep it clean.

To say I’m impressed with Groundworks & their field inspector Dan Southerland would be an understatement. Dan came out for a free inspection & went above & beyond a typical inspection & free estimate to take care of me & set me up for success. He spent over a hour under my house taking over a hundred pictures of my existing support system or lack there of, measuring the moisture in my existing support beams & sub flooring, using his laser level to measure sinkage, and catching issues unrelated to my home structure like a sewer line leak. Utilizing his 31 years of expertise in the industry plus his knowledge as a home inspector, he clearly & kindly communicated to me the stark reality of my 1948 home that has had a few renovations without permitting. He shared big picture the foundation & structural repair my home needs, & then he listened & customized a plan that I could financially make work. He offered me several options. I never felt rushed or pressured. He was in my home for about six hours and even rescheduled his afternoon to make sure we were able to complete. I felt fortunate to have his expertise and support in what has been along an ongoing challenge under my house. I look forward to working with Groundworks and I’m excited to see the end result.

The Team at Groundworks (Tripp, Ryder and Olli) did a fantastic foundation leak repair incorrectly done from a previous remodel. This Team are real pros, great communication, arrived on time, completed the work on time with no surprises or delays. I give Groundworks an A+ on this job and will use their services again without hesitation. Great job Groundworks!

Jose and his Atlanta crew were absolutely amazing. Hard working, polite and respectful. Although hard working does not do this crew justice. They were superhuman! I hope I never need their services mind you, but they were legendary. Great group of young men.

The crew from Groundworks was simply amazing. Joshua W, Charles U, Ty G, and John A were very professional. While they were working outside and under the house, I could hear them talking and they were respectful to each other. No cussing, no yelling, just treating each other like they were valued team members. That really impressed me. Charles U. was training to be a supervisor and he did amazing! I was shocked when we were told this was his first time taking the lead; he did a great job. Once the work was done under the house, they took great pains to ensure the load bearing beams were level and all the jacks were tight. Joshua W. explained everything so well, and truly I was so impressed with these young men! They are a credit to the company and to the kind of men they have grown up to be. As an “old fart”, I hear so much about how the younger generations leave a lot to be desired, but this crew proved them all wrong. There are amazing young men.

The crew was professional, quick and neat. We were thrilled our slider door opened easily after the repair. We had several bids and Groundworks was very reasonably priced. Would definitely recommend!

Had a great meeting with Matthew Wyatt yesterday. He was able to measure our foundation and his tablet was able to produce an accurate as-built of our conditioned crawl space for estimating some additional work we wanted to have done. Matthew was very thorough and knowledgeable.

I had 3 different teams come out for my repairs. First, Roman & his assistant performed the concrete leveling, they did an excellent job & cleaned up all of their debris. It’s very nice to have a level sidewalk & patio!
Second, Kendel & his crew came out to install the leveling/stabilizing portion. I will say it was louder than I expected, almost as much as having a roof replaced. I did have to leave with my dogs because they were stressed. They did a great job also, I was able yo run across my house & jump up & down & there was no bounce! Yay!!
Third, Josh & his crew came out to remove the old insulation & install the “encapsulation” system. That one was a 2 day job. They did a great job, I was able b to mention to Josh about something that seemed off from the leveling & he was able to address it (it wasn’t the work, it was my home’s unique attributes!). I wasn’t aware until we scheduled the work that I needed an electrician for the dehumidifier that’s in the crawl space, I was told that they had their own if I wanted, but I used a local electrician instead.
Overall I am very pleased with each crew that came out, the one thing I told my husband is that the communication was great. From Robert, who came out to inspect & give us a quote, to each crew that performed work. If I had questions they were b great b about answering, if there were issues they’d discusses them with me.
I definitely recommend this company, I hope to find out if the encapsulation does help my electric bill, since w heading into the cold part of the year I’m sure I’ll find out quick.

Let me start off by saying Im super impressed with the site work crew Malik, Andy, and Brian. This crew is very professional, personable, and works REALLY hard! Please be sure to convey this to whoever is in their up-line as they each deserve kudos for being great employees and representatives of Groundworks.
I am very pleased as well with our estimator Zaire. He was always available to answer questions and spent a lot of time with me to make sure I understood the whole process. Zaire made a very expensive endeavor a lot less stressful.

I want to say thank you to Groundworks for helping with my foundation repair.
The first person I met — the inspector, Gardner Kerin — was very clear and honest. He came to our house did free estimate. He spent few hours in my house and explained the problem and the solution in a way I could understand which made me feel more comfortable to move forward with Groundworks. Also, along the whole process, whenever I had issue and question, he was always the first person I can count on. Very professional.
Permit process took little bit time which is expected in my area. Austin also helped me every step away for that.
The crew — Samuel Russu, Sergel, Ivan — were excellent. They arrived on time every day and worked really hard, even when the weather wasn’t great. They were respectful, polite, and very focused on doing the job right. They answered my questions kindly and showed me what they were doing along the way, which made me feel included and informed.
I was also impressed with how clean they kept everything. After they finished, they made sure the work area was tidy and washed my driveway and backyard patio completely.
I really appreciate the effort and care they put into their work. Thank you again to Gardner, Samual and the amazing crew. I definitely recommend Groundworks if you need foundation repair.

Mel Darling from Groundworks Seatac came out to give us an estimate on some uneven sidewalks around our house. She explained the process very clearly and was upfront on the risks and probabilities. Because of the location of the sidewalks there was a chance that their process wouldn't work 100% in some spots. She explained that thoroughly and helped me make an informed decision. We decided to go ahead and it got scheduled reasonably quickly.

Mel put together a very detailed project description for the crew that came out. They were very knowledgeable, professional, efficient, and they cleaned everything up when they were done.

The results were better than we expected. Based on the project plan Mel prepared for the crew, and with their expertise, none of the issues that we had discussed came about and all the uneven spots in the sidewalks are gone.

Mel was great to work with (and just a nice person too) and the crew did very well. I especially appreciate Mel's professionalism, depth of knowledge, and honesty. We would use Groundworks again in a heartbeat.

I tried to schedule a crawlspace inspection with Groundworks twice online, and both times I received on-screen confirmation. No one ever showed up, no confirmation email was sent, and when I finally got through to their national call center, I was told there was no appointment at all.

After explaining that I had already submitted the form twice, the agent offered to rebook me for a date four days later—no attempt to expedite, no ownership, and the usual “we apologize/have a nice day” script.

When a company’s technology fails, the correct answer isn’t “we’re switching systems,” it’s to fix the customer’s problem, not make the customer start over.

Groundworks’ process is broken, their online scheduling doesn’t work, and their text and phone system route you in circles. I needed urgent help after a significant water intrusion, and instead, I received a master class in corporate indifference.
