Every joint.
Sealed tight.
Codena Construction installs caulking and sealants on the joints that keep water, air and weather out of a building — window and door perimeters, curtain wall and storefront, precast facades and expansion joints. From a single house to a commercial tower.

Custom build · frame perimeter
A bead of sealant is the only thing between the weather and the wall.
Windows, doors, cladding and concrete all move — with heat, cold and settling. The joints between them are where water and air find their way in. Done right, a sealant joint flexes with the building for years. Done wrong, it cracks, pulls away, and lets the damage start quietly behind the finish.
Caulking & sealants, ground floor to rooftop.
The same joints show up on a house and on a high-rise — they just get bigger, higher and more demanding. Every one is prepped, backed and tooled properly.
Window & Door Perimeters
The joint between frame and brick, stone, siding or stucco — the most common place for water to get into a wall.
Curtain Wall & Storefront
Mullions, head and sill joints and glazing perimeters on commercial storefronts and aluminium window systems.
Precast & High-Rise Facades
Precast panel joints, window-to-concrete perimeters and sills on mid- and high-rise buildings.
Expansion & Control Joints
Wall-to-slab, wall-to-sidewalk and panel movement joints, sized and backed so the sealant can actually move.
Firestop Sealant
Firestop and smoke sealant at deck flutes, head-of-wall joints and penetrations, installed to the specified system.
Residential Re-Caulking
Windows, doors, siding and trim on homes — failed caulking removed and replaced before it becomes a leak.

Frame-to-post joints
Detail
Black window walls set between cedar posts, under a metal roof. Every frame meets wood, steel and cladding — three materials that all move differently through an Ontario year.
The sealant lines had to do two jobs: keep the lake weather out, and disappear into the architecture. Straight, consistent and colour-matched from deck to soffit.
Brick homes to downtown condos.
Window and door perimeters on low-rise homes and on towers — different heights, same attention to the joint.
Residential
Condo & high-rise
Most caulking fails in the prep. Ours doesn't skip it.
Inspect & quote
We look at every joint — width, depth, substrate and condition — and put a clear written quote in front of you before any work is booked.
Cut out & clean
Old, failed sealant is cut out completely. Surfaces are cleaned and primed where the product calls for it. New caulking over old caulking doesn't last.
Back & bead
Backer rod sets the right joint depth so the sealant bonds on two sides and can stretch. The right sealant goes in for the material and the movement.
Tool & walk through
Every bead is tooled tight and clean, the site is cleaned up, and we walk the finished work with you.
