Questions about building envelope
What is a building envelope?
Everything that separates inside from outside: walls, windows, roof, balconies and the joints between them. Its job is to keep water and air out.
How do I know where water is getting in?
Usually you cannot tell from inside. Water travels along slabs and framing before it shows. A leak investigation traces it on the outside wall.
Do you work from an engineer’s specification?
Yes. Most of our larger repairs follow an envelope consultant’s drawings and are reviewed by them.
Can repairs be done without scaffolding?
Most can. Sealant, flashing, membrane and concrete repairs are all done from ropes or a swing stage.
