Constraction reviews in SeaTac, Washington

Add me to the list of happy Groundworks customers for a concrete leveling repair job that was done professionally, neatly and exactly as promised. The crew was on time and worked hard for close to 6 hours in 90 degree heat. The end result looks great!

Alex, Uri and Luis were absolutely incredible from the time they arrived. Our house was built in 1938 and they took such good care of it and kept us informed the entire time. They secured our foundation, crawl space and basement. There were many times I was very nervous but they reassured me that the house was okay and the process was normal. They left the landscaping better than it was when they arrived! Truly an incredible experience! I cannot recommend them enough.
P.S. When Mike Rowe says they show up in Superman capes he’s not wrong! 😊

Best to get a second bid from Terra Firma, at least you will have something to base it on.
Let my mistake help you …

It’s hard to judge the price when you have nothing to compare it too, I feel the initial 10k was a gimme & the 29k on top of that was for the job! I was left with no invoice for work done or materials. I was also left with no literature on the two sub pumps & air unit that was installed in the space. As far as the sells tactics I feel like the % discount off is a Jedi mind trick to make you feel like you are getting something when you really are not, everyone gets the Discount, don’t be fooled.
I was also informed that it was a four person team vs a three person team, curious did I pay to train to new guy? I feel this company needs to be much more transparent going further that is why you get a score of just two stars.

Jacob N was the lead on this job and was extremely professional & a great communicator. Jacob answered all my questions & took time to explain everything that was going on with the encapsulation, method & product being used to get the job done. The rest of the crew were very quiet & respectful: Richard S, Timothy C & Christian L all keep their heads down (they were in a crawl space, funny) and kept busy.

I had 4 companies come out to inspect my sinking foundation. Groundworks stood out by far. Steve was very knowledgeable and very thorough. He found and explained far more issues than others found and gave me a complete picture of what was going on with my house as a whole. Sam and crew came out to lift and stabilize my foundation and replace the supports underneath. Sam was very communicative throughout the process, making sure I informed on everything they were doing and how it would help the house. I was surprised how quickly they worked. After they finished and cleaned up I couldn't even tell they had dug holes to the foundation. Overall great experience.

The first schedule changed due to the crew being late and not effectively communicating.

Called the office the hour of expected arrival to learn they were running a couple hours late and had to reschedule another day.

The lead for that crew showed up on time and completed the work in a timely manner and seemingly good craftsmanship.

I am however having a bit of buyers remorse given the routing of the power feeds.

I did not realize that this would be as intrusive visually when explained to me the location of the pump which was different than what the salesperson laid out in the drawing.

Not blaming Ground Works, just thought there would be one smaller drain pipe up the wall and had no vision of the battery location.
That’s on me. But the routing of the wires could and should have been better located out of site.

In the end I lost three AC outlets and had to provide an extension chord on my dime.

Overall decent work but things could have been much better.

Update:
Shortly after the completion of the work,Groundworks sent a QA person to have a look.
It was agreed that this could have been done differently.
We are now working on specifics.
The response from Groundworks has been very professional and I have high hopes of quickly having resolution.
Update:
I was sent a new proposal.
It essentially has me paying nearly the same a mount as I originally spent this doubling my cost to have the original issue addressed properly.
I feel this has not been dealt with in a customer friendly fashion. When the company rep came out to look over the work the first time, he indicated things should have been done much differently.
I am somewhat disappointed.

Also, the first real rain came last night and there is still significant water coming into the basement.

This should have, I feel, been addressed in a more effective manner.

At this point, I will not recommend Groundworks.

So, after a couple months of messin about,
Groundworks came out and relocated-the channel drain across the garage door threshold.

Looks better and performs excellent this far-basement is bone dry!

Thank you!

Efficient work process. Kender, Luis, and Asher worked diligently from arrival to cleanup. Great communication thru the entire process by foreman Kender. All questions answered and everything explained during the process. Met all expectations!

Excellent work to repair our crawlspace! Had to redo the entire space from replacing the sump pump to encapsulating the whole area and Jose and his crew were on time and kept me informed along the way. Finished in only 3 days! Mel was amazing at getting us set up and scheduled since we really needed immediate help. Grateful for their help and support and making the space safe, clean and accessible. Thank you to the Groundworks team!

It was a pleasure working with Ernest Vigil. He came to my house and did a thorough measurement of my crawlspace for the estimate. He was responsive throughout the installation process. On the second day of the job, Ernest called me and informed me that the crew told him his map for the job was inaccurate and they had to dig a lot more which resulted in an additional ~$3,500 cost. Initially he was just going to accept what the crew told him. I told him their explanation didn't make sense, and insisted that he should come over to verify. He came after the crew quit working early on that day, went down to the crawlspace and discovered the crew was digging where they are not supposed to.

Then on the fourth day, when I returned from work in the afternoon, the crew was about to leave and told me they had finished everything. I didn't see the new drainage system that was included in the quote so I asked them about this. They said they connected the new sump pump to the old drainage. I remember Ernest told me their company wouldn't use previous systems because you don't know if they still work. So I called Ernest about this. The crew also didn't replace the door which was also included in the quote. I told them about this, they quickly put together a door then left. Fortunately I thought about checking it and discovered all screws were sticking out from the other side of the door with sharp tips (I almost got poked, which was why I noticed it). I told Ernest about this too. He took care of both issues and had the crew come back the next day to fix them. He then came over to inspect the work and took pictures/videos.

So now the system seems to be working fine. Attached is the picture Ernest liked the most.

Terribly unsafe drivers. Would not let us merge on highway 410 with a toddler in the car and nearly ran us off the road.

Super professional! Thanks

Good people

Place of business. Friendly for the career choice

Do to a Haggen grocery store party tray mishap, I volunteered to deliver the rest of their party trays. By the Grace of God, I arrived through traffic from Lake Tapps to Sea Tac just in time for their Company Christmas Party. A few lovely ladies insisted that I stay and join their party. Before I knew it I had a name tag on and a glass of wine in my hand. I had a fabulous time playing the role of a "party crasher". What a wonderful group of people. The experience made me wish I had an Engineering degree. I would love to work for this Amazing Family. May God Bless the entire Staff and their families with Health, Happiness and Prosperity, In Jesus name Amen

Their team is knowledgeable, efficient, and courteous, ensuring that projects are completed on time and within budget. The quality of work is exceptional, and they exceeded my expectations in every way. I highly recommend SCI for any construction needs - they truly know how to get the job done!

This company almost killed my son last week! A lazy driver neglected to clean his truck after empty, threw a baseball size rock into the windshield of his pickup. Extreme lack of responsibility and accountability! No offer to pay for my son’s windshield. Out of pocket $300. This was FAR FROM A ROAD HAZARD! Stay safe from these folks! They don’t care about you!

This company allows their employees to operate trucks while impaired. This morning one of their drivers blew through a stop sign nearly hitting my dog and I. I made a split second decision to jump in a bush and shield my dog to avoid. Steer clear of a company that ignores dangerous behaviors.

Your drivers are terrible, one just ran a red light on Ellingson . They then went straight in a turn only lane almost side swiped my car. Truck 300/080 trailer plate number 7501-te . I would highly recommend drug testing them! Very erratic. Will be reporting to DOT as well.

While driving on the freeway this week one of their trucks was hauling massive chunks of rocks without a cover or anything for that matter. My windshield ended up getting cracked after JUST replacing it last week. As I got photos of the truck the driver was laying on his horn. Called the company to at the very least get an apology and couldn’t even get a call back. My windshield is insured but the audacity to ignore a safety issue while owning a business is absolutely insane. Seems to me that they will ignore every safety hazard until it causes someone to lose their life over it. Do better .

Miracle worker

Amazing work! Highly recommend Mike and his team

Great techs that came to the house, they were very kind and did all the work in just an hour. Very thankful for their professional nature and timeliness.
