About our facade sealing in Longfield Hill
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure for clients around Longfield Hill. Coping and flashing joints are included where sealant is the specified fix. We work on cladding panel joints, window and door perimeters and coping and flashing joints, and the failures we are asked to look at most are gaps between rainscreen or cladding panels and weathered joints at frame-to-structure perimeters. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Longfield Hill, preparation and product choice get the time they need.
In the countryside around places like Longfield Hill, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Leave it or put it right?
Topping up a failed joint usually buys very little time. A full cut-out and fresh bead is the repair that holds. Older rural buildings around Longfield Hill move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Why us?
- Specification-led, product-correct work
- One phone line for London, the South East and Scotland
- Old sealant cut out, never sealed over
- Colours chosen to suit frames, cladding or finishes where possible

Questions we’re asked in Longfield Hill
Is Longfield Hill too small for you to travel to?
Not at all. Longfield Hill is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Would you work within a site like Gravesham Community Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you provide access for facade work?
That varies with the building and the access on offer. When you call 01277 525 020 or email the details over, describe the access, and we’ll agree the approach together.
Can you find out why a window is leaking?
Yes. We look at the perimeter sealant and tell you whether it has failed before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
Work for main contractors and building owners
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Share access with other external trades
- Don’t wait for a second leak before calling
- Keep sills, gutters and drainage paths clear
- Avoid patch repairs on failed facade joints
Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed instead of soaking the joints.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail.
Our process
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Longfield Hill need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- We start with photographs, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and both faces cleaned back.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
What we need from you
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000
- Explain the parking and delivery arrangements
Ask for a quote
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email a schedule or drawings.

Do you need facade sealing in Longfield Hill?
Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.
Clients typically get in touch after noticing something like this:
- Damp patches beside frames after rain
- Unsightly perimeter sealant on a visible elevation
- Old perimeter mastic that has dried out
- Draughts around frames and panels
On a healthcare site such as Gravesham Community Hospital (4 miles north of Longfield Hill), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What to look for in a quote
- Whether primer will be used where the manufacturer specifies it
- How the existing material will be dealt with
- Health and safety accreditation such as CHAS
- Can the work be phased to keep areas open?
Building and refurbishing in Longfield Hill
Central London is about 20 miles from Longfield Hill. 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. Longfield Hill 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 external mastic is timed for workable conditions and agreed with the site manager.
When a school such as Istead Rise Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. For contractors on a campus like University of Greenwich, 4.6 miles to the north-west of Longfield Hill, facade and perimeter sealing has to fit around students and term dates.
