Questions

Is it worth restoring my windows rather than replacing them?

Usually, yes. Original timber is often better quality than modern softwood, and a restored window can last for decades. It also keeps the character of the house and is often required for listed buildings.

Is lead paint a problem?

Older windows often have lead paint, so we assume they do and work in a way that keeps dust to a minimum. We also use extraction equipment rated for lead-based paint when removing old paint.
