My husband and I built a Ryland home in Thornwood six years ago. We have had: leaks in the roof, failed seals in the windows causing condensation in between the panes, leaking front door causing damage to floor in the front hall all the way down to the joists in the basement, sagging floor on the second story, water leaks in the master bedroom, family room, living room and master bathroom, seriously faded siding, leaking window in the 2nd bedroom and office. I could go on but I don't want to bore you. By the way, we spent $330,000 on this house in 2001. I can't even tell you how much money we have poured into this house since we moved in. We are not the only people to have problems with them also. Many people in our community have had similar or even worse problems. There is a website for "Ryland complaints"--I don't remember the address, but I'm sure you could google it. We haven't moved simply because we LOVE our neighborhood and our lot.
Unfortunately, most builders are putting out the same product. Supposedly Cambridge homes is a little better than most, but they also cost more.
Good luck to you!
