About our construction mastic in Greatham
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. We work on cladding and panel joints, internal decorators’ caulk and sanitary and kitchen joints, and what we are called in for most is mastic snags holding up handover and early adhesion failures on new external joints. One point of contact handles commercial sealant work in Greatham from the first photos to the final walk-round, for single jobs and planned programmes alike.
In the countryside around places like Greatham, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What the job involves on each surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line, and any bath is loaded with water first where that’s the agreed method.
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit, depending on what suits the programme.
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Greatham are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
Preparing the site
- Share your working hours and any access restrictions
- Agree which areas must stay open
- Point out parking and an unloading spot

Advice
Common problems we fix in Greatham
On construction sites, joints normally fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, so they end up back on the snag list.
What tends to prompt an enquiry:
- Window and door perimeters that won’t pass inspection
- A long mastic snag list close to completion
- New external sealant already peeling away
- Oversized or tapered gaps around new frames
Hospital estates such as Chase Hospital, 2.5 miles north-east of Greatham, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
What to look for in a quote
- Their plan for phasing and protecting the area
- What the guarantee covers, and for how long
- How the existing material will be dealt with
- Is the sealant right for the movement and the substrate?

Quotes vary with the job. Expect it to depend on:
- How much there is to seal
- Whether the work must be split into stages

Building and refurbishing in Greatham
Greatham is about 45 miles from central London. 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. The South East is one of the drier parts of the UK. 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.
Units on estates such as Longmoor Enterprise Park, under half a mile north-east of Greatham, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Projects at schools like Greatham Primary School work to term dates, so mastic is programmed tightly.

Why act early in Greatham
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple. Older rural buildings around Greatham move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Questions we’re asked in Greatham
Is Greatham off your patch?
Not at all. Greatham is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is Longmoor Enterprise Park, near Greatham, within your area?
Yes. Our area takes in Greatham and its surroundings, with estates and business parks such as Longmoor Enterprise Park included. Photos and a short description are enough for a first look.
Is the mastic package guaranteed?
It carries a 12-month guarantee on our workmanship. We carry five million pounds of public liability insurance.
What happens if the weather stops external sealing?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Sealing in poor conditions risks adhesion failure.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Do you do internal caulk as well as external mastic?
It depends on the specification, but frames, sanitary, kitchens, caulk where specified and snagging are typical.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
