Facade sealing in Well Hall
Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. We work on stone and brick facade joints, coping and flashing joints and window and door perimeters, and the usual reasons a site gets in touch are cladding panel joints that have opened up and weathered facade joints that have lost their grip. Whether you call it commercial sealant work, mastic application or joint sealing, in Well Hall it comes down to the same thing: the right product in a properly prepared joint.
Around Well Hall, as across London, much of the work is refurbishing existing buildings as well as building new ones. 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.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Should maintenance staff do it?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Questions about Well Hall
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we will work to them. All of Greater London is inside the ULEZ, and our planning allows for it
Will you take on work at estates like Green Lane Business Park, close to Well Hall?
Yes, sites like Green Lane Business Park are within our area, along with the rest of Well Hall. To start, just give us a call on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
How many days will you need on site?
It depends on the scope, but the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you run new sealant over the existing bead?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you replace failed glazing units?
No. A glazing contractor handles that. What we seal are the joints around frames and panels.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
Mastic packages on Well Hall sites
A 2-mile radius around Well Hall takes in several hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. The ULEZ covers the whole of Greater London, Well Hall 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.
For contractors at a college like Shooters Hill Sixth Form College, 1.3 miles north-east of Well Hall, perimeters and internal sealant are timed for the holidays. Work at a hotel such as The Eltham Hotel (to the south-east of Well Hall) tends to be programmed around bookings, mastic included.

Work for main contractors and building owners
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Do you need facade sealing in Well Hall?
Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.
Things that normally lead to an enquiry:
- Damp patches beside frames after rain
- Facade joints cracked through the middle
- Perimeter joints where frames meet the structure
- Air leaks through failed facade joints
For contractors on a campus like University of Greenwich - Avery Hill (1.4 miles south-east of Well Hall), facade and perimeter sealing has to fit around students and term dates.

On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
Preparing the site
- Flag any permit to work we’ll need
- Warn occupants and staff about the work
- Arrange parking or a loading space

Why it’s worth doing now in Well Hall
Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What the job involves on each surface
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification with a product suited to glazing perimeters.
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, and primers go on where specified.
