How we handle facade sealing in Welling
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. We work on stone and brick facade joints, perimeter joints where frames meet the structure and window and door perimeters, and what we are called in for most is air leaks through failed facade joints and failed seals around shopfront and entrance frames. Facilities teams, main contractors and managing agents in Welling tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

What sealant work can’t fix
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Installing or repairing glazing systems
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Render or concrete edges that have broken away
If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
What we seal
- Coping and flashing joints
- Window and door perimeters
- Perimeter joints where frames meet the structure
- Cladding panel joints
- Shopfront frames
- Stone and brick facade joints
Questions we’re asked in Welling
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
Do you take on work at healthcare sites like Memorial Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you replace failed glazing units?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Will rain stop the work?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.

Different surfaces, different methods
Cladding panel joints
Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface, often a low-modulus silicone or hybrid.
Brick and stone facades
Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use, and mask the edges carefully.
Mastic packages on Welling sites
As part of Greater London, Welling is inside the ULEZ, which applies to every van on site. Delivery slots and scarce storage shape how and when the mastic goes in. Welling has several hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Hospital estates such as Memorial Hospital, 2.1 miles west of Welling, 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. University estates such as University of Greenwich Avery Hill Campus, 1.6 miles south-west of Welling, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. School extensions, at buildings such as Danson Primary School, typically run to the summer holidays, mastic included.
Welling is about 9 miles east of London, in Greater London. Our applicators travel to Welling for work on facade joints. We work across 764 places in Greater London, large and small. Sites around London have their own page, roughly 9 miles from Welling.
We take on facade joints across the DA16, DA15 and DA6 postcode area, whatever the building. We cover commercial and managed buildings on Days Lane, Hook Lane and Lyme Road. Welling sits on or close to the A207, which helps when planning parking and deliveries for the job. Nearby places we also cover include Crook Log (1 mile east), Blendon (1 mile south-east), Upton (1 mile east), Bexleyheath (1 mile east) and West Heath (1 mile north-east) for facade joints. Bigger towns within reach include London (9 miles west), City of Westminster (12 miles west), Marylebone (12 miles west), Kensington (14 miles west), St Pancras (11 miles north-west) and Shoreditch (9 miles north-west).
What’s near Welling
Around Welling, our work takes us to commercial buildings near Nags Head pub, Danson Park and Bexley Grammar School and the streets around them. Welling’s nearest station is Welling station, roughly 0.5 miles north-west of the centre. A little further out are Greenwich Castle (5 miles west) and Broadway Shopping Centre (1.6 miles east). Green spaces nearby include The Tarn and Summer Hill.
Looking after the joints
A few simple habits keep the new joints working:
- Share access with other external trades
- Add perimeter sealant to planned maintenance checks
- Report water ingress at frames as soon as it shows
- Check that rainwater leaves the facade the way it was designed to
Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed rather than sitting against the joints.
Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.
Quoting for work in Welling
Before we quote, we look at:
- How much there is to seal
- Location, for remote and island sites
- The site’s rules and procedures
- Whether the work must be split into stages
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
Before you send an enquiry
For an accurate fixed quote, we need to understand the site. Useful things to include:
- The asbestos register, for older buildings
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
- The type of building and who uses it
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or email the details over.
From enquiry to sign-off
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. All of Greater London is in the ULEZ, and kerbside space in Welling can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- Send your site hours and access windows
- Confirm the product named in the specification
- Explain the parking and delivery arrangements
