at the spencer house we rehab billtated 20 hung windows. thissa the meeting rail and forms a weather skeel. the meeting rail rotd and was no longer sound. everything else was in wonderful shape. we took 20 of these guys out in a nice assembly line fashion. we moved the old rail with a tricky joint retrofitted these. that meant we had all the original historic dmrasz and sashes and we were able to do that for a hundred dollars a window which is far cheaper than the replacement costs. >> we have a member of the planning department who can help us. >> one of the things the planning department is charged with is preserving our neighborhood character. one of the most obviously features of a building is it's windows. if you come in with a replacement window permit and you are suggesting to pvinyl windows in where it was wood we will send that permit upstairs and have someone look at to see if you are degrading the building if you had a house with aluminum windows and you want to put in wood windows that help restore the character of that building
