Sealant specialists in Leamouth
Inside a commercial building, sealant does a lot of quiet work: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Outside, it closes facade joints, frame perimeters and movement joints against the weather. Our applicators work on both the inside and the outside of the building. If you have weathered facade sealant that no longer flexes and water staining near frames, panels or ceilings, we can put it right. Most enquiries from Leamouth start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In an occupied building in Leamouth, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. The right product goes on each, in a colour chosen to suit where the joint is seen.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

On site: what to expect
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For a job in Leamouth, 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 will schedule to suit.
- First, details come to us: photos, drawings or a schedule of the areas.
- We work out why the joints have failed and fix a quote for the agreed scope.
- Before anything is cut out, we agree access, timings and sequence.
- We strip the failed bead and prepare both faces of the joint.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Finished joints are checked with you and handed over with our 12-month guarantee.
Before we start on site
- Explain the parking and delivery arrangements
- Send any specification or drawings in advance
- Clear stock, furniture or equipment away from the joints

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Common questions from Leamouth clients
Do you take on jobs in Leamouth where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Can you work at a site such as Manor Road Retail Park, by Leamouth?
Yes. Estates, retail parks and business parks around Leamouth, Manor Road Retail Park among them, are all within reach. A few photos and the unit address let us price the work.
How long does a job like this take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Does commercial sealant work come with a guarantee?
It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited and a Constructionline member.
Can you take on work for an FM or managing agent?
Yes, and through main contractors too. You send the details, we return a fixed quote, and the job is done and signed off.
Why deal with it now?
Some low prices are low because nothing gets cut out. Sealing over looks tidy at handover, then lifts once the joint starts moving. Every quote we give includes full removal and preparation. Getting scaffold, permits or access booked in Leamouth takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Surface by surface
Shop fronts and retail fit-outs
Most shops can’t close for a reseal. We plan around the access windows the store gives us.
Washrooms and toilets
Mould that has grown into washroom sealant can’t typically be cleaned out. The lasting answer is removal, preparation and a new sanitary bead, room by room if that suits the building.
Cost factors for sealant joints
These are the things that shape the price:
- Whether the work must be split into stages
- Specialist products, such as fire-rated or hygienic sealants
- Site requirements such as inductions and permits
- Whether old sealant has to be cut out first
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Sending details for a quote
A few photos plus some basic facts will normally do. Please tell us:
- When you need the work done
- Photos of the joints, close up and from further back
- Anything awkward about access or site hours
- What the building is and how it’s used
For a fixed quote, phone 01277 525 020 or send details through our quote form with the site address and an outline of the work. Our quote form is another easy route.
After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Add sealant to the planned maintenance inspection list
- Note dates and locations of sealant work for future planning
- Check the asbestos register before anyone disturbs old sealant in an older building
We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records, and tell us if a joint we sealed gives trouble within that time.
Once sealant fails in a movement joint, grit and debris get in. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.
Common problems we fix in Leamouth
If sealant tears through its centre, it has failed cohesively. Typically the movement was too much for the sealant chosen because the bead was too thin, the joint over-stretched or the movement class wrong. The same product in the same joint tends to fail the same way.
Common reasons buildings call us in:
- Untidy joints in a reception, shop floor or lobby
- Layers of sealant, all of them failing
- Leaks that seem to come through a sealant line
- Frame mastic that has hardened and come away from the wall
For a hotel such as Good Hotel London, which lies east of Leamouth, the colour of a joint at the bar or the bath matters to the look of the room.
