About our construction mastic in Bosham Hoe
Perimeter sealing outside needs a dry joint and the right temperature. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal areas can typically carry on while the outside waits. We work on sanitary and kitchen joints, cladding and panel joints and window and door perimeters, and the usual reasons a site gets in touch are new external sealant already peeling away and inconsistent sealant finishes from plot to plot. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Bosham Hoe, that means joint design, primers and backing rod as standard.
Construction in and around smaller places such as Bosham Hoe 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 covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Stick to the specified sealant rather than a generic substitute
- Plan external elevations with the weather in mind
- Protect sealed areas from following trades
- Brief the final clean team to avoid blades near sealant
Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault which is why protection after sealing matters.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We flag them as soon as we see them.
Site staff or a sealant specialist?
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.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Why act early in Bosham Hoe
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go, and avoids repeated visits. We can run snagging as its own phase before handover. Older rural buildings around Bosham Hoe move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Is Bosham Hoe too small for you to travel to?

Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
What happens if the weather stops external sealing?
External mastic depends on conditions: each sealant has a temperature range, and the joint must be dry. We plan external elevations with that in mind.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Surface by surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly, and any bath is loaded with water first where that’s the agreed method.
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control and we install what’s specified.
