Joint Sealing
Caulking & Joint Sealing Services
Different joints require different preparation and sealant systems. We assess the location, substrate, movement requirements and exposure before selecting an appropriate product.
Residential Caulking
Professional caulking around internal joints, tiled areas, bathrooms, kitchens, skirting interfaces and other suitable residential applications.
Commercial Caulking
Joint sealing for suitable commercial areas including wall junctions, floor interfaces, wet areas and construction details.
Expansion & Construction Joints
Preparation and flexible sealing of suitable expansion, movement and construction joints.
Balcony & External Sealing
Perimeter, wall, tiled-area and external joints prepared and sealed using products suitable for the application.
Windows & Door Frames
Clean caulking around suitable window and door frame interfaces, including internal and external junctions.
Bathrooms & Wet Areas
Silicone and flexible joint sealing around showers, tiled wet areas, baths and suitable bathroom junctions.
Flexible Sealing for External Joints
External joints are exposed to weather, temperature changes, building movement and general deterioration. Failed or separated sealant should be properly removed and the joint prepared before new sealant is applied.
Nextline Services provides practical joint-sealing solutions for balconies, tiled external areas, walls and other suitable building joints.
Signs Your Sealant May Need Replacing
Age, movement, weather and substrate conditions can cause joint sealants to deteriorate over time.
Cracked Sealant
Visible cracking through an existing sealant bead can indicate deterioration or joint movement.
Separated Edges
Sealant that has pulled away from one or both sides of the joint may require removal and replacement.
Missing Sealant
Gaps or missing sections can leave the joint exposed and create an unfinished appearance.
Deteriorated Silicone
Old silicone may become brittle, stained, loose or difficult to maintain.
Movement Joints
Flexible movement joints require products and joint preparation suited to the intended application.
Weathered External Joints
UV, rain and temperature exposure can contribute to deterioration of external joint sealants.
Internal & External Applications
Balconies
Perimeter joints, wall junctions and suitable tiled-area joints.
Bathrooms
Shower, bath, tiled wall and wet-area silicone junctions.
Windows & Doors
Internal and external frame interfaces where suitable.
Concrete Joints
Suitable construction, movement and expansion joints.
Wall Junctions
Selected internal and external building junctions.
Tiled Areas
Flexible perimeter and movement joints within tiled areas.
Commercial Areas
Joint sealing for suitable commercial building applications.
External Areas
Weather-exposed joints where suitable sealant systems are required.
Professional-Grade Joint Sealants
Not every joint requires the same sealant. Product selection depends on the substrate, joint type, expected movement, exposure and location.
We focus on correct preparation and selecting a sealant system appropriate for the intended application rather than applying one product everywhere.

Caulking & Joint Sealing FAQs
Do you remove the old sealant first?
Where existing sealant has failed or deteriorated, it is generally removed as part of preparing the joint before new material is installed.
Do you seal balcony joints?
Yes. We provide joint sealing for suitable balcony perimeter, wall and tiled-area joints.
Do you do expansion and construction joints?
Yes, for suitable applications. The joint condition, width, substrate and movement requirements need to be considered before choosing the sealant system.
Do you do bathroom silicone?
Yes. We provide silicone replacement and wet-area joint sealing for showers, baths and suitable tiled bathroom areas.
Can I send photos for a quote?
Yes. Clear photos showing the full area and close-ups of the affected joints are useful when preparing an initial quote.
