About our facade sealing in Crofton
We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause. If the evidence points away from the sealant, we say so before quoting. We work on perimeter joints where frames meet the structure, coping and flashing joints and shopfront frames, and what we’re called in for most is gaps between rainscreen or cladding panels and previous reseals run over old sealant. A single leaking joint is often how a building in Crofton 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.
Construction in a London area such as Crofton means working on constrained sites: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Facade sealing around Crofton: how the place shapes the job
The area within 2 miles of Crofton holds several hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. The ULEZ covers the whole of Greater London, Crofton included, so site vehicles need to meet its standards or pay the daily charge. Deliveries are booked and storage is tight, so mastic materials come in as needed.
When a school such as Crofton Infant School is extended or refurbished, the mastic package is often squeezed into the holidays. New units and refits on sites such as Halo Business Park (to the north-east of Crofton) need their panel and perimeter joints sealed to the specification.
Crofton is about 1 mile south-west of Orpington, in Greater London. Across the BR6 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Crofton is one of 764 places we cover in Greater London for facade joints. For work in that direction, see our London page (11 miles or so).

Your questions answered
Will you plan work around the academic year at somewhere like University of Greenwich Avery Hill Campus?
Yes. We plan campus work around teaching, exams and residence turnarounds. 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 take on a job at a hospital such as Orpington Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How many days will you need on site?
That varies with the scale of the job, but the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For bigger or phased jobs, we’ll set out a timescale with the quote.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Can staff carry on working while you are here?
In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
What sets the cost
Before we quote, we look at:
- Whether old sealant has to be cut out first
- Working within restricted access windows
- How much there is to seal
- Joint width, depth and condition
Pricing facade joints depends on quantities, condition and access. Ask us for a fixed quote.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- Specification clauses that apply
- The asbestos register, for older buildings
- Where the site is, with the postcode
- How the joints are reached, and at what height
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.
What we are called out for in Crofton
Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. When the joint edges need repair first, we say so.
Site and facilities staff are often the first to spot these:
- Cold air coming in at window perimeters
- Sealant pulling away from frames or panels
- New sealant peeling off old mastic
- Gaps between rainscreen or cladding panels
Hospital estates such as Orpington Hospital, 1.1 miles to the south-east of Crofton, 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.
Questions to ask before you book
- Will failed sealant be removed rather than covered?
- Are they CHAS accredited or on Constructionline?
- Will CSCS-carded applicators be on site?
- Their approach to joint depth and backing

When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Work on the window or framing system itself
- Specialist high-level access methods
- Joints whose design needs changing by the specifier
Not sure which it is? You can call 01277 525 020 or email the details over and we will tell you honestly.
Joints and surfaces we work on
- Stone and brick facade joints
- Window and door perimeters
- Cladding panel joints
- Coping and flashing joints
- Perimeter joints where frames meet the structure
- Shopfront frames
Aftercare for building managers
For the best life from the joints:
- Confirm the survey covers external sealants in older buildings
- Insist on a full cut-out when joints are renewed
- Add perimeter sealant to planned maintenance checks
- Share access with other external trades
Keep a note of which product went in and when. Future work can then match the product and colour without guesswork.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail instead of after the damage.
