About our construction mastic in Stock
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal sealing often fills those days. If you have mastic snags holding up handover and external joints sealed in damp or cold conditions that are now failing, we can put it right, on cladding and panel joints, window and door perimeters and internal decorators’ caulk alike. Most enquiries from Stock start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Sites around smaller places like Stock 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.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Deciding which fire-stopping product a penetration needs
- Joint design decisions that belong to the architect or engineer
- Damage to finishes by other trades after we’ve sealed
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.
Joints and surfaces we work on
- Sanitary and kitchen joints

Other services in Stock
From enquiry to sign-off
On arrival, 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 usually taking a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. Jobs in and around smaller places like Stock are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- Drawings, the sealant specification and your programme come to us for pricing.
- You receive a fixed quote listing scope, products and phasing.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- We close out snagging and hand over with a 12-month guarantee.
Getting the site ready
- Agree which areas must stay open
- Share the asbestos register for older buildings
- Tell staff and tenants when we’ll be in

Different surfaces, different methods
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer and we install what’s specified.
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Commercial clients in Stock
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Why act early in Stock
A quick bead over a damaged joint can get an area past inspection. New sealant laid on old or dirty sealant has nothing to bond to and the defect reappears in the defects period. 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 Stock. Photos of every joint help us quote for the whole job.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
Why clients in Stock choose us
- Work to your specification and the manufacturer’s guidance
- Colours chosen to suit frames, cladding or finishes where possible
- Commercial sealant work since 2005
- Colours confirmed for the specified product

New build and refits around Stock
Rainfall across the South East, Stock included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. At about 26 miles from central London, Stock is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
Hotels like Greenwoods Hotel Spa and Retreat, under half a mile to the north of Stock, rarely close for long, so refurbishment mastic is phased floor by floor. Extensions at sites like Mayflower Community Hospital (to the south-west of Stock) typically sit beside working departments, and the mastic follows strict access rules. Historic houses such as Ingatestone Hall (to the west of Stock) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
