What we see on Waterloo homes
The median house in Waterloo went up in 1991, and 51.9% of the town was built from 1990 onward. 4,651 housing units, 76.9% of the occupied ones owner-occupied. Mostly owners, then, which usually means the decision turns on how long you plan to stay rather than on what it does to a rent roll. 15.2% has been built since 2010, so a fair number of these are original builder units reaching the age where the glass seal goes before anything else does.
Houses built after 1990 came with vinyl siding and double-glazed windows from new, so this is rarely a rescue job. It is a replacement at the end of service life, and that changes what is worth doing. The wall system behind is usually sound, which moves the decision away from repair and onto material and profile: Alside vinyl, or Ascend Composite if you want the look of real wood. On windows specifically the number that matters is how many openings are actually costing you. We will quote the worst room on its own if that is the sensible place to start.
