When to call us in Marsh Green
Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink and internal caulk in a moving joint is normally the first to crack. Picking a flexible sealant where there’s movement keeps snags down.
Any of the following is a good reason to get the joints checked over:
- Snag items on joints that need redoing before handover
- New external sealant already peeling away
- A mastic package split between trades with no clear owner
- Sanitary sealant damaged by following trades
With historic properties like Hever Castle (to the east of Marsh Green) in the area, refurbishment work often meets old masonry that needs compatible sealants.
Questions to ask before you book
- Will CSCS-carded applicators be on site?
- The named product and why it was chosen
- Are they CHAS accredited or on Constructionline?
- Their plan for phasing and protecting the area
Construction mastic in Marsh Green
Getting a subcontractor through site induction should be simple. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We work on cladding and panel joints, sanitary and kitchen joints and internal decorators’ caulk, and what we’re called in for most is mastic snags holding up handover and external joints sealed in damp or cold conditions that are now failing. One point of contact handles commercial sealant work in Marsh Green from the first photos to the final walk-round, whether it’s one building or several.
Conversions of older rural buildings near smaller places such as Marsh Green bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
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.

Should maintenance staff do it?
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.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Marsh Green: questions and answers
Is hospital work, at somewhere like Edenbridge and District War Memorial Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can the mastic package for our job in Marsh Green follow the site programme?
Yes, we work to the programme and the sequence the site sets. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature 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 will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
What happens if the weather stops external sealing?
Outside, the joint has to be dry and the temperature within the product’s limits. Damp, frost or condensation on frames can stop work.
Do your applicators hold CSCS cards?
We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. Public liability insurance of five million pounds is in place too.

Looking after the joints
Keep the joints in good shape with a few simple steps:
- Put any product change through the designer first
- Get the mastic subcontractor involved early in the programme
- Ask installers to correct oversized gaps first
- Keep scrapers and abrasive pads off new beads
The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last so packing or adjustment by the installer comes first. We flag them as soon as we see them.
What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Damage to finishes by other trades after we have sealed
- Joint design decisions that belong to the architect or engineer
If you are not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer.
What we seal
- Cladding and panel joints
- Brick and block movement joints
- Window and door perimeters
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Floor and skirting junctions

Central London is about 23 miles from Marsh Green. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. Marsh Green sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.
On a healthcare site such as Edenbridge and District War Memorial Hospital (0.9 miles north-east of Marsh Green), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Surface by surface
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.
