About our construction mastic in Higher Denham
Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list, and every return visit costs time. We seal so the snag list stays short. If you have caulk cracking where joints are moving more than expected and missed perimeter joints on a new elevation, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Higher Denham, that means joint design, primers and backing rod as standard.
Construction in and around smaller places such as Higher Denham is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Ask cleaners to use soft cloths around fresh sealant
- Release areas for mastic once other trades have finished in them
- Record the products used in the O&M file
- Put any product change through the designer first
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last. We flag them as soon as we see them.

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once.
