How we handle mastic sealing in Clare Market
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. Most enquiries involve mastic failing across several blocks on an estate and communal area joints that look neglected, on balcony and threshold joints, communal kitchens and washrooms and communal entrances and stairwells. Whether you call it commercial sealant work, mastic application or joint sealing, in Clare Market it comes down to the same thing: the right product in a properly prepared joint.
Across Greater London, Clare Market included, the ULEZ applies, and parking and loading rules differ from street to street. For block-wide work, a place to park and store materials saves time on every visit.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What happens if it’s left?
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Failed sealant in a building in Clare Market can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Common questions from Clare Market clients
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’ll work to them.
Is Grand Vitesse Industrial Estate, near Clare Market, within your area?
Yes. Estates, retail parks and business parks around Clare Market, Grand Vitesse Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
How long does a job like this take?
It depends on the scope, but the work typically takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Do you supply RAMS and insurance details?
We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
On site: what to expect
Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Preparing the site
- Let building users know which areas are affected
- Share your working hours and any access restrictions
- Arrange parking or a loading space
Request a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Surface by surface
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Planned maintenance
Resealing can be scheduled alongside other planned works, building by building.
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Masonry that has broken away beside the joint
- Asbestos-containing sealant, which we don’t remove
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can call 01277 525 020 or send details through our quote form and we’ll tell you honestly.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
