We bought a new home in Brighton in 2018 from Ehrenburg that had been built on spec. It had sat on the market for some time (buyers likely were scared off by certain aspects of the yard) so we got it for an excellent price. It is a gorgeous house and we are happy with it.
For any warranty issues, Ehrenburg has been fantastic and gone above and beyond in some cases (like even arranging for a plumbing fix after our one year warranty expired). They are usually quick to respond to e-mails (best way to let them know about issues as there is a paper trail) and are always great to deal with.
We did have a couple of issues not covered by warranty. The grading - ugh we needed a few truckloads of dirt to fill in a hole because our neighbours downspout (also an Ehrenburg home) was pointed towards our house. Some settling is expected, but this was excessive. Not expensive to fix, just got free dirt from various places, but involved a bunch of shoveling. The downspout also caused sinking of our walkway, which requires mudjacking to fix. Not ridiculously expensive to fix, but still crappy.
The concrete on our driveway also is in rough shape - less than 2 years later and there is significant spalling - but to be honest... many homes by different builders have similar issues in our neighbourhood.
Other issues we had, were all addressed, and mostly were minor paint/drywall and little plumbing issues, plus some issues with doors and a window and the kitchen exhaust vent. They fixed them all up with no hassle other than having to wait for their trades to come in, and left us very happy.
In the end, we still are still super happy with our home after our first year. This is in large part due to their awesome service department! Plus our house is beautiful, and was an excellent value for the money especially considering the quality of the finishes (engineered hardwood floors and ceramic tile, quartz counters, upgraded mechanicals, etc.). We love the layout, it's well thought out, and we still feel like we got an excellent deal.
I would enthusiastically recommend Ehrenburg in the future!
