When should a lintel be replaced?

Signs include diagonal cracks from window corners, sagging brickwork, rust jacking, or stuck windows/doors. Steel lintels corrode and expand over time causing structural cracking. We assess and provide the right repair approach.

Do you replace brick sills with limestone?

Yes. Limestone or precast sills shed water better than brick sills. We remove the brick rowlock sill, install flashing and drip edges, and set a durable one-piece sill correctly sloped to drain.

How long does a sill/lintel project take?

Most single openings are completed in a day. Multiple openings or structural remediation can take 2–3 days. Weather and access can affect scheduling.
