Advice
About our construction mastic in East Peckham
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility. We work on floor and skirting junctions, sanitary and kitchen joints and cladding and panel joints, and the failures we are asked to look at most are a long mastic snag list close to completion and window and door perimeters that won’t pass inspection. Most enquiries from East Peckham 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.
Conversions of older rural buildings near smaller places such as East Peckham bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Surface by surface
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, and we use a flexible sealant where there’s movement.
External facade and movement joints
Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it and work only when conditions suit.
Looking after the joints
A few simple habits keep the new joints working:
- Bring the mastic contractor in after the last trades are through
- Get the mastic subcontractor involved early in the programme
- Brief following trades on areas that have been sealed
- Keep scrapers and abrasive pads off new beads
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating, and a delay to handover. Checking perimeters before internal finishes go on avoids it.
When to bring in a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
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.
FAQs: East Peckham
Is a smaller place like East Peckham outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Will you plan work around the academic year at somewhere like Hadlow College?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can you seal external joints in wet or cold weather?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Wet or cold joints cause adhesion problems so it’s better to wait.
What will the job cost?
There isn’t a price list, as every site differs. Send photographs or drawings and we’ll price it at a fixed figure.
Can you fit around our programme?
Working to your programme, we seal each area as it’s handed over. The sequence is settled with your site team and updated as the programme moves.
Do you guarantee new-build sealant work?
It carries a 12-month guarantee on our workmanship. We’re also fully insured for public liability.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

What sealant work can’t fix
Some faults sit outside our scope, and we say so rather than covering them up:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Damage to finishes by other trades after we have sealed
- Deciding which fire-stopping product a penetration needs
If you are not sure, just ring 01277 525 020 or send details through our quote form and we will give you a straight answer.
Joints and surfaces we work on
- Brick and block movement joints
- Window and door perimeters
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Cladding and panel joints
- Floor and skirting junctions
How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Specialist products, such as fire-rated or hygienic sealants
- Travel to remote or island sites
- How accessible the joints are
- Working within restricted access windows
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.
Details that help us quote
Whether it’s one area or a whole building, these details speed things up:
- Where the site is, with the postcode
- Anything awkward about access or site hours
- Clear photos of the problem areas
- Any dates the work must fit around
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Contractors’ notes for East Peckham
East Peckham is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team. East Peckham is about 29 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.
Hospital estates such as Tonbridge Cottage Hospital, 5.4 miles south-west of East Peckham, 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. With historic properties like Old Soar Manor, 4.5 miles north-west of East Peckham, in the area, refurbishment work often meets old masonry that needs compatible sealants. For contractors at a college like Hadlow College, 2.5 miles west of East Peckham, perimeters and internal sealant are timed for the holidays.
East Peckham is about 5 miles east of Tonbridge, in Kent. We cover commercial sites throughout East Peckham, for single jobs and planned programmes alike. We work across 931 places in Kent, large and small. London is covered too, some 29 miles away.
