How we handle facade sealing in North End
Facade sealants sit in the sun, rain and frost every day, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. Most enquiries involve old perimeter mastic that has dried out and damp patches beside frames after rain, across window and door perimeters, stone and brick facade joints and shopfront frames. Whoever orders the work in North End, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Contractors’ notes for North End
North End has a good number of hotels close by, all within 2 miles. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. Site traffic in North End falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in.
For contractors refurbishing units at places like Berghem Mews Business Village, 0.7 miles north-west of North End, the mastic covers cladding panels, roller-door and window perimeters. Work at a hotel such as Kensington West Hotel, less than half a mile to the north of North End, tends to be programmed around bookings, mastic included. For a contractor working at a hospital such as Charing Cross Hospital, 0.6 miles south-west of North End, perimeter and facade sealing is planned around patients and deliveries.
North End is about 1 mile south of Kensington, in Greater London. Any commercial site in North End is covered. We work across 764 places in Greater London.

What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Installing or repairing glazing systems
- Joints whose design needs changing by the specifier
- Water getting in through cracked render or porous masonry
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think.

Your questions answered
Can you work around term dates at a campus such as University of Westminster?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Berghem Mews Business Village, near North End, within your area?
Yes. Estates, retail parks and business parks around North End, Berghem Mews Business Village among them, are all within reach. A few photographs and the unit address let us price the work.
What site paperwork can you supply?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
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.
Do you cover North End?
Yes. We take on work across North End.
Can you look at water coming in around a frame?
Yes. We check the sealant joints and report what we find before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Leave it or put it right?
Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. In North End, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

What sets the cost
To price the job, we consider:
- Travel to remote or island sites
- The total length or number of joints
- How accessible the joints are
- Backing rod, priming and other preparation
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
Sending details for a quote
However big the job, the same details help:
- The postcode of the building
- Specification clauses that apply
- Any dates the work must fit around
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
How the job changes by surface
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use, and mask the edges carefully.
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end.
Diagnose, treat, sign off
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. In North End, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and both faces cleaned back.
- 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.
Before we start on site
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use
- Arrange parking or a loading space

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email drawings and photos to discuss it first.

Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Don’t wait for a second leak before calling
- Inspect facade joints on a regular cycle
- Avoid harsh cleaners on facade sealant
- Note when each elevation was last resealed
Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.
Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in.
