When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Leaks from pipework, wastes or valves (that’s plumbing)
- Structural cracks or movement the joints weren’t designed for
- Roof leaks that only look like a joint problem
If you are not sure, just call 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
What we seal
- Washrooms and tea points
- Window and door perimeters
- Floor and threshold joints
- Movement joints in walls and floors
- Kitchen worktops and splashbacks
- External facade joints
Commercial mastic work in Westbourne
Most of the buildings we seal stay open while we are there. Work is scheduled around the site hours and access windows you give us; phasing keeps some washrooms, kitchens or entrances available while others are done. That applies whether the building is an office, a shop, a hotel, a college or a care home. Site teams most often ask us about a top-up bead over failed sealant, now lifting and shrunken sealant along kitchen worktops and splashbacks, on washrooms and tea points, movement joints in walls and floors and kitchen worktops and splashbacks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Westbourne it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
We price commercial jobs in Westbourne from photographs, drawings or a site visit, and the scope is set out in writing.
Work in smaller places such as Westbourne tends to come one building at a time: a pub kitchen, a hall, a small office. We will want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What affects the price in Westbourne
These are the things that shape the price:
- Whether old sealant has to be cut out first
- How much there is to seal
- Access and working height
- Working within restricted access windows
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
There’s no need for a formal survey. These details are enough to start:
- Clear photos of the problem areas
- Any dates the work must fit around
- Drawings or a marked-up plan, if available
- What the building is and how it’s used
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call 01277 525 020 or use the quote form.
Keeping the joints sound
To get the most from the new sealant:
- Report cracked or peeling sealant early
- Add sealant to the planned maintenance inspection list
- On pre-2000 buildings, share the asbestos information before work starts
- Have extract fans checked so wet areas dry out
Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records.
Sealant installed at the same time usually fails in sequence. The first failures are often a warning about the rest so the whole run is worth inspecting. We’ll tell you which sealant joints need doing first and which can wait.
What happens if it’s left?
Putting off a reseal typically moves the cost rather than avoiding it. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below, which brings decorators and flooring contractors into the repair. Resealing while only the sealant has failed keeps the job small. Halls, stores and units around places like Westbourne may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Pricing sealant joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

Questions we’re asked in Westbourne
Will you take on work at estates like Hambrook Business Park, close to Westbourne?
Yes. We cover Westbourne and the area around it, including industrial estates, business parks and retail parks such as Hambrook Business Park. Send details of the unit and the work through our quote form for a quick quote.
Is a smaller place like Westbourne outside your area?
Not at all. Westbourne is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it.
Could the old sealant in an older building contain asbestos?
It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and if something is suspected, work stops until it’s tested.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you work for facilities managers and managing agents?
Yes. FMs, managing agents and landlords are among our regular clients as well as contractors. We can work to your instruction process and site rules.
