Everything you need to know before booking
What is a lintel?
A lintel is a beam placed above windows and doors. Its job is to carry the load from the wall above and transfer it to the sides.
Why do lintels fail?
Lintels fail due to rust (if steel), cracking (if concrete), or rot (if wood). Water penetration, age, and improper installation are common causes of failure.
What does a window sill do?
A window sill creates a structural base for the window. It protects the wall from water damage and helps improve energy efficiency by providing thermal insulation.
How can I tell if my window sill is damaged?
Look for cracks, crumbling material, water stains below windows, or gaps between the sill and wall. Damaged sills often allow water to enter the building.
What materials are best for window sills?
Natural stone like Indiana limestone is best for durability against weather. It is cost-efficient, easy to maintain, and adds decorative value to buildings.
Can damaged lintels cause structural problems?
Yes. Failed lintels can cause cracks in walls above windows and doors. They can lead to sagging, uneven floors, and in severe cases, structural collapse if not repaired.
