Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Plan racking layouts so feet don’t land on a joint
- Inspect movement joints alongside other routine building checks
- Report split or peeling joint sealant early
- Leave barriers in place until fresh joint sealant has cured
Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load and the reseal becomes an edge repair as well. A sound seal keeps the joint working.
Expansion joint sealing in Lower Green, done properly
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed, and the sealant in them keeps water and debris out. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors. Site teams most often ask us about debris jammed in movement joints and car park joints leaking onto vehicles below, on precast concrete panel joints, cladding panel joints and blockwork control joints. For commercial sealant work in Lower Green, you deal with one contact from quote to sign-off, whether it’s one building or several.
Jobs around smaller places like Lower Green are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Our process
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. Jobs in and around smaller places like Lower Green are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Preparing the site
- Have the specification and drawings to hand
- Flag any permit to work we will need
- For older buildings, check the asbestos register before work

Lower Green: questions and answers
Is a smaller place like Lower Green outside your area?
Not at all. Lower Green is within our area. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Does your area include sites such as Ham Barn Business Park, near Lower Green?
Yes. Estates, retail parks and business parks around Lower Green, Ham Barn Business Park among them, are all within reach. A few photographs and the unit address let us price the work.
Are you fully insured?
Yes. We are fully insured, including public liability cover.
Can you quote from photographs?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
What’s the difference between an expansion joint and a movement joint?
The general name is movement joint, and expansion joint is one common type. On site, people tend to use them interchangeably.
Quoting for work in Lower Green
A fixed quote reflects the actual work. It allows for:
- Distance, for remote addresses
- The size and state of each joint
- Access and working height
- Phasing around occupants
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote when you are ready.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- The type of building and who uses it
- The product your specification calls for
- Whether an asbestos survey exists
- Anything awkward about access or site hours
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

General trades versus a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
