Professional Movement Joint Sealant Services
Specialist movement joint sealing for commercial buildings
SD Team installs and reseals movement joints across facades, floors, glazing perimeters and curtain wall details. This forms part of a wider sealant offer that covers application across the full building envelope, giving contractors a single trade partner for joint sealing scope.
Where we apply movement joint sealant
External facade movement joints
Facade movement joints accommodate thermal and structural movement on commercial buildings. We apply movement joint sealant to specification across brick, render, cladding and panel-faced facades. This protects the building envelope and keeps joint lines consistent across long facade runs.
Internal floor and slab joints
Internal slab joints in commercial buildings and warehousing need durable sealant that can take traffic and movement. Our teams install movement joint sealant across concrete, screed and resin floor systems. This maintains finish continuity in operational and high-use environments.
Glazing perimeter and curtain wall details
Glazing perimeters and curtain wall interfaces include movement joints that allow the system to flex without compromising the seal. We apply compatible movement joint sealant across these interfaces. This supports weather resistance and long-term performance of the wider glazing system.
Resealing on refurbishment projects
Aged movement joints often fail through sealant degradation, joint movement and weathering. We remove deteriorated material and reseal joints with a compatible new sealant system. This is particularly relevant on commercial refurbishment, retrofit and maintenance programmes.
Specialist commercial sectors
Hospitals, education buildings, transport hubs and large mixed-use developments all rely on movement joints performing across long building runs. SD Team supports specification and application across these settings. This addresses joint scope as part of a wider building envelope package.
Why choose us for movement joint sealant
Repair instead of replacement
Where existing movement joints have failed, resealing the joint with a compatible system is often more practical than rebuilding the wider detail. This supports value-engineered refurbishment without compromising long-term performance.
Support for live operational environments
SD Team works across sectors where access, presentation and programme control all matter. Resealing on occupied commercial buildings and live operational sites is planned around the building in use.
Nationwide teams
Our regional teams cover the UK, supporting movement joint sealant application on single sites and across multi-region commercial programmes for tier-one main contractors and developers.
Project-led support
From specification stage through to application sign-off, we work with main contractors and specifiers to confirm the right sealant system for each joint location. This protects compliance and long-term performance.
Movement Joint Sealant FAQs
Our movement joint FAQs cover the most common questions we receive from main contractors, specifiers and facilities teams about scope, specification and application.
What is movement joint sealant for?
The aim of movement joint sealant is to seal a designed joint while accommodating the structural or thermal movement that joint is allowing for. It keeps the joint weather-tight, durable and visually consistent.
Can existing movement joints be resealed?
Yes. Where the joint substrate remains sound, deteriorated sealant can be removed and replaced with a compatible new material. Full rebuild is not always the sensible answer where the joint structure itself is intact.
Do you work to manufacturer specification?
In many cases, yes. SD Team applies movement joint sealant to manufacturer specification, including approved applicator requirements where relevant to the system being installed.
What is the difference between movement joints and expansion joints?
It can be, depending on terminology. Expansion joints are one type of movement joint that allows for thermal expansion specifically. Movement joints cover both structural and thermal movement in a building.
How do I know if my movement joints need resealing?
Common signs include cracking, splitting, detachment from the substrate and visual gaps along the joint line. For more information, see why movement joint sealant fails and what contractors should look for.
Do you cover the whole UK?
Yes. SD Team operates nationwide with regional teams, supporting movement joint sealant work across single sites and large multi-region commercial programmes.
