Different surfaces, different methods
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s for gaps that stay still and get painted.
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services. Tell us what records you need and we’ll confirm with the quote.
Construction mastic in Tapnage, done properly
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 clearing them late eats into the handover window. We seal so the snag list stays short, area by area through the programme. We work on floor and skirting junctions, window and door perimeters and internal decorators’ caulk, and the usual reasons a site gets in touch are internal caulk splitting as the building dries out and a mastic package split between trades with no clear owner. Whether you call it commercial sealant work, mastic application or joint sealing, in Tapnage it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Conversions of older rural buildings near smaller places such as Tapnage 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.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

After the work
After handover, a little attention goes a long way:
- Stick to the specified sealant rather than a generic substitute
- Protect sealed areas from following trades
- Flag uneven or tapered frame gaps early
- Don’t force external sealing on a damp or frosty day
Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault, so protecting sealed areas matters.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure. We raise them during our first walk of the area.
When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Frame gaps too wide for sealant, which the installer needs to correct
- Faulty frames rather than failed sealant
- Deciding which fire-stopping product a penetration needs
If you’re not sure, just phone 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

How a job runs
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. Smaller jobs around Tapnage can be grouped with others nearby. A fixed quote is given before anything starts.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- Warn occupants and staff about the work
- Point out any areas we must not close
- Send asbestos survey details if the building is pre-2000

What sets the cost
We price every job individually. The things that drive the figure:
- Joint width, depth and condition
- Induction, permit and paperwork requirements
- Location, for remote and island sites
- How much existing material needs removing
There’s no price list, since every building and every scope is different. Call for a quote.
What to include in your enquiry
Diagnosis starts before we arrive. Tell us:
- How the joints are reached, and at what height
- The postcode of the building
- The type of building and who uses it
- Any dates the work must fit around
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
When to call us in Tapnage
On construction sites, joints normally fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, so they end up back on the snag list.
Typical triggers for a call:
- A mastic package split between trades with no clear owner
- Caulk cracking where joints are moving more than expected
- Snag items on joints that need redoing before handover
- Frame perimeters left unsealed or poorly sealed
For contractors refurbishing units at places like Knowle Village Business Park, 0.7 miles to the south-east of Tapnage, the mastic covers cladding panels, roller-door and window perimeters.
What to look for in a quote
- Will CSCS-carded applicators be on site?
- Which product they’ll use, and why it suits the joint
- Their approach to joint depth and backing
- Can the work be phased to keep areas open?
Common questions from Tapnage clients
Can you work around term dates at a campus such as Fareham College?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Would you work within a site like Fareham Community Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure.
Can you quote from photographs?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can fire-rated sealing at service penetrations be included?
Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. Fire-stopping design and sign-off sit with the designer and building control.
Sites and facades in and around Tapnage
Tapnage 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, which is why external dates are agreed with the site manager. At about 64 miles from central London, Tapnage is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.
When a college such as Fareham College (2.8 miles south of Tapnage) builds or refurbishes, the mastic package normally has to fit around students and staff. School extensions, at buildings such as The Henry Cort Community College, typically run to the summer holidays, mastic included.
