Construction Company reviews in Portland, Oregon

Antonio did a wonderful job. We had a concrete step reconfigured and replaced and redid a tricky part of an old walkway from the driveway. The work is flawless! In addition, he and his crew constructed some fencing and installed a gate with much better hardware than we had there before. Yes, we would definitely recommend AG GENERAL CONTRACTOR. If you want a good general contractor, call them. They do great work!

I am always so happy with Tony’s work. He listens to what I want done, makes suggestions that are reasonable and even better than my plan at times. I have recommended Tony to several of my coworkers and friends.. and will continue to have him back for future projects.

Antonio and his team at AG General Contractor LLC did some small concrete patches for us. The estimate was reasonable, their work was efficient, and the results were great. My spouse liked that they didn't take over the driveway and that they cleaned up and took all their tools.
I was impressed enough to request an estimate for paver and fencing work, and again his pricing was reasonable. He'll be starting soon, and I'm looking forward to marking more projects off the to do list.

This was removal and replacement of a section of our sidewalk due to root uplifting. Job was well executed, and fully cleaned up. Bid was similar to 2 other bids I had solicited. Antonio was really easy to work with.

I was very happy with the work that Antonio did to restore our existing outdoor fireplace. He was very fast to provide a quote and then proceeded to do the project in a timely manner. We are happy with the results and will be calling him for future projects.

Antonio was great to work with. He and his crew were on time, communicated well, and did a fantastic job. We will be hiring him for more projects in the future.

I was recommended AG General Contractor to come out and do some concrete washing and sealant along with replacing 20+ specialty bricks on my retaining wall. Antonio and his team did an excellent job along with cleaning things up after job is finished. His pricing is excellent compared to others. I would totally recommend Antonio and his team to anyone. He earn my business and look forward to have him work on my future house projects. Again, thanks for the great job!

Antonio is really reliable, fast and easy to work with. He kept us updated on the progress and did an amazing job repairing the sidewalk. Highly recommended for concrete services.

Antonio rebuilt our 40 foot retaining wall and also replaced our failing fence posts. We had several contractors come out to see our retaining wall and all had said they would need to rebuild the wall entirely from scratch and require all new materials, which was very costly. Without prompting, Antonio immediately said he could just build the wall using the existing stone which saved us thousands of dollars. He and his crew take a lot of pride in their work and are just genuinely nice people to work with. Antonio’s communication is excellent - he is prompt with providing bids and scheduling work. Their pricing is very fair. We will definitely be hiring them for more work in the future. Glad to have found this gem of a company!

I rarely give negative reviews, but we were so dissatisfied with AG General and Antonio I have to provide a fair warning.
Our job was an asphalt driveway/side yard with paver border.
Antonio and the crew were very nice and worked hard but he should never have taken our job. He does not know how to do asphalt and does not have the equipment for it.
Mistakes happen but the lack of acknowledgment until other contractors told him the job needed to be completely ripped out made us lose faith.
The job has now been redone and we’re trying to get Antonio to pay for part of it, but haven’t heard from him for a while.
Update: Antonio has reached out to remedy the outstanding balance.

AG was hired to repair a stone retainer wall and fix a falling fence. Incredibly efficient and excellent work! Very communicative and friendly as well which is a cherry on top of good artistry.

Antonio has been an absolute pleasure to work with. Not only was he very communicative but the quality of work he completed for a driveway replacement was top notch. I work for a Property Management company and he exceeded all expectations. Super easy to work with and excellent quality work. Thank you for all you do Antonio and we will continue to utilize your services.

Worked with AG on a multipart/day project where he and his team expanded a slope, built a retaining wall around that slope, carved out a section for gravel + wood stairs, and then backfilled the top with 1/4 clean crush gravel for a low maintenance finish. You can tell there was a lot of care and detail that went into leveling out the area, digging out the soil, moving it to the wall area, and getting that pretty square corner out of these curved blocks!

The right side of the stairs (looking at it) is sloped and supported by the dirt that's also supporting the retaining wall. The left side is a sharp dirt edge which we left like that with a bit of a gap for a future fence, so no point smoothing it out. Very communicative, happy to make adjustments, double checked that everything was well explained before working on it, and reasonably priced. They got this job done in no time and made some intense work look easy, highly recommend.

IDK what this is

I am a Realtor and have used Sierra on several jobs and recommended them on more. They are timely, fair and do great work! Call them first!

Fantastic. Sewer repair was done well at a fair price. Excellent communication and integrity. Highly recommend!

The team at Sierra Excavation are the best in the industry. I had them install a new sewer line, water line, and rain drains on my remodel. They do quality and professional work.
