A window that won't close properly is usually down to worn hinges, a frame that's warped or shifted slightly out of alignment, or a build-up of paint or debris in the frame — all of which are normally repairable without replacing the whole window.
Timber window frames can swell with damp weather and shrink back in dry conditions, which over time can leave a frame slightly out of true even if it was fitted perfectly originally. uPVC frames don't suffer from swelling in the same way, but their hinges and mechanisms wear over time just like any moving part, and can drop or stiffen enough to stop a window closing and locking cleanly.
A window that closes but lets in a draught is a slightly different problem, usually down to a failed or perished seal around the glazing or frame rather than an alignment issue — the window closes fine, but no longer seals against the weather the way it did when new.
In most cases these are repairable: adjusting or replacing hinges, correcting the frame alignment, or replacing a failed seal. Full window replacement is really only necessary where the frame itself is significantly rotten or structurally damaged, which is a smaller proportion of cases than people often assume. This is a common repair across both older and newer properties in Preston and Lancashire, since hinges and seals wear out regardless of a property's age.
