Sealant specialists in Westmill
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. Externally it keeps rain out of frame perimeters, panel joints and movement joints. We deal with internal and external sealant joints alike. We work on external facade joints, kitchen worktops and splashbacks and washrooms and tea points, and the usual reasons a site gets in touch are a top-up bead over failed sealant, now lifting and hardened, chalky sealant on south-facing or exposed elevations. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Westmill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In an occupied building in Westmill, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.
Business units in the countryside around places like Westmill are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
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.
How the job changes by surface
Fire-rated seals where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. Fire-stopping design and sign-off sit with the designer, fire engineer or building control, and we install to the specification.
Shop fronts and retail fit-outs
Most shops can’t close for a reseal. We plan around the access windows the store gives us.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Cracking that needs a structural engineer to look at it
- Roof leaks that only look like a joint problem
- Leaks from pipework, wastes or valves (that’s plumbing)
If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think before you book.
Joints and surfaces we work on
- External facade joints

What shapes the price:
- How much there is to seal
- The size and state of each joint
- Whether the work must be split into stages
- Any access equipment needed
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Your questions answered

Yes. A large share of our work comes through facilities managers, managing agents and landlords as well as contractors. Tell us how you issue work and we will fit in.
Is failed sealant stripped out, or sealed over?
Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip.
Do you check for asbestos before removing sealant?
Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
