When to call us in Bopeep
Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, so they end up back on the snag list.
Look out for the following:
- External joints sealed in damp or cold conditions that are now failing
- Window and door perimeters that won’t pass inspection
- Sanitary sealant damaged by following trades
- Cracks opening in caulked internal joints
Units on estates such as North Downs Business Park (3 miles south of Bopeep) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Construction mastic for commercial buildings in Bopeep
We work to the specification and the programme rather than whatever product is to hand. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. Most enquiries involve a mastic package split between trades with no clear owner and old sealant on a refurbishment that needs stripping before new work, on sanitary and kitchen joints, cladding and panel joints and brick and block movement joints. A single leaking joint is often how a building in Bopeep first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. Mastic is usually one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Why deal with it now?
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. A single mastic package gives one point of responsibility, with the same standard on every plot. Getting scaffold, permits or access booked in Bopeep takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Questions we are asked in Bopeep
Do you cover business parks and estates near Bopeep, such as North Downs Business Park?
Yes, sites like North Downs Business Park are within our area, along with the rest of Bopeep. Photos and a short description are enough for a first look.
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Do you install fire-rated sealant as part of a package?
Where it’s specified, yes, working to the specification and the manufacturer’s installation guidance. If the detail calls for collars, wraps or batts instead, we’ll tell you.
Can you work to our specification?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
Do your applicators hold CSCS cards?
Our applicators hold CSCS cards, and we are CHAS accredited and a Constructionline member. We are also fully insured, with five million pounds of public liability cover.
How long does a typical visit take?
That varies with the scale of the job, but the work normally takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
What we can’t put right
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
- Rework caused by others damaging completed areas
- Glazing units that are cracked or misted
Not sure which it is? You can call 01277 525 020 or use the quote form and we’ll tell you honestly.

Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by.

Cost factors for mastic packages
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Travel to remote or island sites
- The total length or number of joints
- Working within restricted access windows
- Which sealant the job calls for
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.
What to include in your enquiry
Good information means a firmer quote. Helpful details to send:
- Where the site is, with the postcode
- Any dates the work must fit around
- How the joints are reached, and at what height
- The asbestos register, for older buildings
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, call 01277 525 020 or use the quote form.

Building and refurbishing in Bopeep
As part of Greater London, Bopeep is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
With Bopeep inside the ULEZ and kerb space scarce, we sort access and loading before the first day on site. Older buildings in the area around Bopeep, such as Lullingstone Castle, which lies east of Bopeep, need care when sealed: the product has to suit soft or historic materials.
Bopeep is about 3 miles south-east of Orpington, in Greater London. We cover commercial sites throughout Bopeep. Bopeep is one of 764 places we cover in Greater London for mastic packages. We also cover London, some 14 miles away.
We take on mastic packages across the BR6 postcode area. For a building on Shoreham Lane and Hewitts Road or nearby, send details and we will quote for mastic packages. If your building is just outside Bopeep, we cover Maypole (1 mile north), Well Hill (1 mile north-east), Chelsfield (1 mile north-west), Badgers Mount (1 mile south) and Pratt's Bottom (1 mile south-west). A short drive away, we cover London (14 miles north-west), Shoreditch (15 miles north-west), Whitechapel (15 miles north-west), Stockwell (14 miles north-west), Orpington (3 miles north-west) and Plaistow (13 miles north-west).
Local landmarks in Bopeep
Locally, jobs take us to sites close to St Olave's and St Saviour's Grammar School, The Bo-Peep pub and Hewitt's Chalk Bank. Bopeep’s nearest station is Knockholt station, roughly 0.6 miles south-west of the centre. A little further out are London Borough of Bromley Museum (2.4 miles north-west) and Lullingstone Castle (2.5 miles east). The countryside around Bopeep includes The Warren.
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Keep finished joints away from paint, plaster and scrapers
- Put any product change through the designer first
- Ask installers to correct oversized gaps first
- Release areas for mastic once other trades have finished in them
Record which products went where in the handover file. Future maintenance is easier when the products are known, and tells you what to reseal with. We can confirm the handover information you need when we quote.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating and possibly a delayed handover. A check of every frame before decorators start is worth the time.
