He wasted time by having me watch a video of their process, and attempted to get me to agree to a proposal the day of - estimates running in the $15k-$50k ranges. Their estimates came in higher than their competitors by about $5k including Groundworks. When I informed him that I would not be using their services, he replied with, "What are your plans for your sagging floors? How do you plan to address this?" I have met with many contractors on this same issue, and no one else aside from Groundworks and TerraFirma has attempted to blow our issues out of proportion. However, Noah did offer to do a side by side comparison of the other offers with his, which I did not take. I ungraciously assumed it wouldn't have been attempt to price match, but to take another opportunity to push me more on his proposals. Don't use them, if you want to avoid fear mongering and overpriced services.

TerraFirma sent over an estimator, then scheduled repairs. They were done in less than one working day and provided photos. They laid down paper to protect the floor as they were working.

Folks in the office were helpful and responded quickly. Would hire again if needed.

It is obvious he has years of experience working with foundations and understands engineering very well. There was no pressure to make any quick decisions.

The experience was much better than expected, considering the issues we are facing with our old home. I highly recommend Ram Jack West and ask for Chris.

The discs are supposed to be installed below the frost line--NOT ON TOP OF THE GROUND. Also, in many places, the posts they used are not even connected to the beams.

Paul at Allied worked with me over the course of four months figuring out the best way to deal with the problem. The solution was a channel drain that would lead to my existing gutter drainage system. Because of the topography of my existing driveway, I assumed that there would still be a fair amount of puddling even after the drain was installed and that I would just have to live with it. In the days just after the install however, it rained quite a bit, and the drain worked pretty much perfectly. The puddling has been reduced by about 95%, and the water that does collect is shallow enough to handle easily. After the rain stops, the remains evaporate after a few hours. The small lake that I used to have to walk around is gone. The guys who did the install were professional and very courteous and Paul was very knowledgeable and patient in response to my many, many questions and emails leading up to the install. Would definitely recommend Allied for any project, large or small.

I told him I did not want a whole new driveway, just a repair. He said he'd come by to have a look on a Thursday and never showed. Never tried to contact me again. When I do have a large concrete job, I will not use this company. I'm feeling generous with the 3 stars, but I don't really want to hurt this business.
