About our construction mastic in Three Ashes
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. If you are dealing with window and door perimeters that won’t pass inspection and inconsistent sealant finishes from plot to plot, we can put it right, on window and door perimeters, internal decorators’ caulk and floor and skirting junctions alike. One point of contact handles commercial sealant work in Three Ashes from the first photographs to the final walk-round, whether it’s one building or several.
Sites around smaller places like Three Ashes can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.
Work we carry out in Hampshire comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email drawings and photos and we will arrange a return visit.

What the job involves on each surface
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move.
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.
How the quote is worked out
Each job is priced on its own details. The main factors are:
- Travel to remote or island sites
- Joint width, depth and condition
- Induction, permit and paperwork requirements
- How accessible the joints are
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Sending details for a quote
To price the job accurately, we need to understand the site. Useful things to include:
- A wide shot and a close-up of the area
- Any dates the work must fit around
- Any specification or named product
- What the building is and how it’s used
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Specifying the product where the designer hasn’t
- Faulty frames rather than failed sealant
- Oversized gaps that need packing or adjustment by others
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we’ll say what we think.
What we seal
- Internal decorators’ caulk
- Brick and block movement joints
- Sanitary and kitchen joints
- Window and door perimeters
- Floor and skirting junctions
- Cladding and panel joints
General trades versus a specialist
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and our waste is bagged and taken away as we go. Smaller jobs around Three Ashes can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First we take quantities off the drawings and read through the specification.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Before we start on site
- Flag any permit to work we’ll need
- Share the asbestos register for older buildings
- Have the specification and drawings to hand

What happens if it’s left?
A quick bead over a damaged joint can get an area past inspection, but it rarely lasts. New sealant laid on old or dirty sealant has nothing to bond to. We cut out and redo the joint properly. One visit to deal with every failing joint makes more sense than several trips to a place like Three Ashes, rather than one at a time. Photos of every joint help us quote for the whole job.
Pricing mastic packages depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
What you get with us
- RAL and finish matching where the product range allows
- A range of standard colours, depending on the product
- Over 20 years of commercial sealing
- Fixed quotes based on photographs, drawings or a visit

Contractors’ notes for Three Ashes
Rainfall across the South East, Three Ashes included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. Central London is about 44 miles from Three Ashes. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.
For a contractor working at a hospital such as Basingstoke and North Hampshire Hospital, 4.8 miles to the south of Three Ashes, perimeter and facade sealing is planned around patients and deliveries. Recladding or extending a unit at a site like Berry Court Business Park (to the south-west of Three Ashes) brings panel joints and frame perimeters into the programme. With historic properties like The Vyne, 2.8 miles to the south of Three Ashes, in the area, refurbishment work often meets old masonry that needs compatible sealants.
