Construction mastic in Exton, done properly
Mastic is often where a new building first shows its quality to the client. Untidy or missed joints are among the commonest snag items, and every return visit costs time. We seal so the snag list stays short, area by area through the programme. We work on sanitary and kitchen joints, floor and skirting junctions and cladding and panel joints, and the failures we are asked to look at most are sealant knocked or painted over by other trades and failed sealant in an existing building being refurbished. Facilities teams, main contractors and managing agents in Exton tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Sites around smaller places like Exton can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What the job involves on each surface
Window and door perimeters
Internal perimeters are typically sealed with a paintable product where decorating follows. We follow what’s specified with colours matched to the frame where needed.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Frame gaps too wide for sealant, which the installer needs to correct
- Damage to finishes by other trades after we have sealed
- Approving fire stopping as compliant
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly.

Your questions answered
Is Exton too far out for you?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Can the mastic package for our job in Exton follow the site programme?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you come in just for snagging?
Yes. We clear snags by redoing joints rather than patching them.
Do you guarantee new-build sealant work?
Our workmanship carries a 12-month guarantee from sign-off. The guarantee covers our work, not later damage by other trades.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
What do you charge?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.
What happens if the weather stops external sealing?
Outside, the joint has to be dry and the temperature within the product’s limits. Frosty or damp mornings can hold up external sealing so we normally switch to internal work when that happens.
On site: what to expect
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. If others near Exton need work, visits can be combined. A fixed quote is given before anything starts.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Flag any permit to work we’ll need
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote

Related advice
Should maintenance staff do it?
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Mastic packages on Exton sites
At about 57 miles from central London, Exton is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. Exton sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.
With historic properties like Hinton Ampner House (4.2 miles north of Exton) in the area, refurbishment work often meets old masonry that needs compatible sealants. School extensions, at buildings such as Meonstoke Church of England Infant School, typically run to the summer holidays, mastic included.

Why it’s worth doing now in Exton
Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area usually clears more for less disruption, and avoids repeated visits. Snagging can be priced as a separate stage. Around Exton, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

How the quote is worked out
We price every job individually. The things that drive the figure:
- How accessible the joints are
- The product specified
- Site requirements such as inductions and permits
- Joint width, depth and condition
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.
What we need to price the job
It doesn’t need to be a full survey. A few details are enough to get going:
- The site address and postcode
- Specification clauses that apply
- Drawings or a marked-up plan, if available
- Access details, including height
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or send photos by email with what you know.
