About our facade sealing in Little Chelsea

Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we’ll fit the work around it. We work on coping and flashing joints, perimeter joints where frames meet the structure and shopfront frames, and what we are called in for most is facade joints cracked through the middle and staining on stone next to old sealant. Whether you call it commercial sealant work, mastic application or joint sealing, in Little Chelsea it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around Little Chelsea, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.

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.

Little Chelsea: questions and answers

Would you work within a site like Chelsea and Westminster Hospital?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will you take on work at estates like Brompton Cross District Shopping Centre., close to Little Chelsea?

Yes. Our area takes in Little Chelsea and its surroundings, with estates and business parks such as Brompton Cross District Shopping Centre. Included. A few photos and the unit address let us price the work.

Can you find out why a window is leaking?

Yes. Photos help, and you can call 01277 525 020 or send photos by email to arrange a visit. Many frame leaks are sealant failures, though not all.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Should we check old sealant for asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. We don’t remove asbestos-containing materials.

Can you handle several sites?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

Surface by surface

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair first.

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. We avoid acetoxy silicone, which can stain some natural stone.

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Little Chelsea can sit alongside others in a wider programme across Greater London.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Mastic packages on Little Chelsea sites

Site traffic in Little Chelsea falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in. The area within 2 miles of Little Chelsea holds a good number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

For contractors at a college like St Mellitus Theological College, 0.7 miles to the north-west of Little Chelsea, perimeters and internal sealant are timed for the holidays. Recladding or extending a unit at a site like Brompton Cross District Shopping Centre., 0.8 miles to the north-east of Little Chelsea, brings panel joints and frame perimeters into the programme. Extensions at sites like Chelsea and Westminster Hospital (to the west of Little Chelsea) normally sit beside working departments, and the mastic follows strict access rules.

How a job runs

Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For a job in Little Chelsea, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Share your working hours and any access restrictions
  • Warn occupants and staff about the work
  • Let us know about inductions and permits

Why act early in Little Chelsea

Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. In Little Chelsea, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we can’t put right

We check first that sealant really is the fix. It won’t put right:

  • Water getting in through cracked render or porous masonry
  • Movement beyond what any sealant can handle
  • Cracked or spalling substrates that need repair before sealing

If you’re not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer.
