Different surfaces, different methods
Cladding panel joints
On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.
Facade sealing in Limehouse
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you have patch repairs that keep failing and weathered joints at frame-to-structure perimeters, we can put it right, whatever the surface. A single leaking joint is often how a building in Limehouse first comes to us: we look at the rest while we’re there and tell you what we find.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Do you need facade sealing in Limehouse?
Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.
Most enquiries start with something like this:
- Old perimeter mastic that has dried out
- Cladding panel joints that have opened up
- Staining on stone next to old sealant
- Damp patches beside frames after rain
On a campus such as University of Cumbria in London, 0.5 miles to the south-east of Limehouse, new teaching buildings and residences are typically built and refurbished around the academic year.

Contractors’ notes for Limehouse
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Limehouse. Deliveries are booked and storage is tight, so mastic materials come in as needed. A 2-mile radius around Limehouse takes in plenty of hotels. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.
On a healthcare site such as The London Independent Hospital, which lies north-west of Limehouse, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Hotels like Point A Hotel London Canary Wharf, 0.6 miles to the south-east of Limehouse, rarely close for long, so refurbishment mastic is phased floor by floor.
Limehouse is about 2 miles east of Whitechapel, in Greater London. Any commercial site in Limehouse is covered, for single jobs and planned programmes alike. Limehouse is one of 764 places we cover in Greater London.

For a walk, there’s St. James's Park Lake and Tower Hill.
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Avoid harsh cleaners on facade sealant
- Clear debris that holds water against joints
- Don’t wait for a second leak before calling
- Never let anyone seal over old sealant
Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.
Get the joint design right when resealing: 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.
From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. Planning a London job such as one in Limehouse starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Before we start on site
- Have the specification and drawings to hand
- Agree which areas must stay open
- Make sure the joints can be reached

Related advice
General trades versus a specialist
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.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Why deal with it now?
Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice. Failed sealant in a building in Limehouse can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.

Questions about Limehouse
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Will you plan work around the academic year at somewhere like University of Cumbria in London?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Do you offer coloured sealant?
It depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
Do you use silicone for external joints?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.
Is it okay to overlay old mastic?
No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Is the work guaranteed?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
