Is the old sealant taken out first?
Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip.
How we handle commercial sealant contractors in Upper Walthamstow
A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. If you have damp patches where an external joint has failed and gaps behind commercial kitchen worktops and sinks, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Upper Walthamstow it comes down to the same thing: the right product in a properly prepared joint.
On a typical commercial building in Upper Walthamstow, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.
Around Upper Walthamstow, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. The right product goes on each, in a colour chosen to suit where the joint is seen.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

What happens if it’s left?
A cheaper quote sometimes means the old bead stays in. New sealant laid on old silicone has nothing to bond to, so it peels. Our prices always include removal of the failed bead and full joint preparation, because that’s what makes the new bead last. In Upper Walthamstow, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Surface by surface
Fire-rated seals where specified
Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. The design and sign-off of fire stopping belong to the designer and building control; we install what’s specified.
Window and door perimeters
Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. The product depends on whether the joint will be painted, matched to the frame colour where colour matters.
Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Redoing a failed joint normally costs more than getting it right at the outset, 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.
Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First, details come to us: photos, drawings or a schedule of the areas, or we arrange a site visit.
- We work out why the joints have failed and fix a quote for the agreed scope.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- 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.
Preparing the site
- Tell staff and tenants when we’ll be in
- Arrange parking or a loading space
- Tell us which areas need to stay in use

Cost factors for sealant joints
The price varies from site to site. Expect it to depend on:
- Any access equipment needed
- The total length or number of joints
- The size and state of each joint
- Site requirements such as inductions and permits
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
What to include in your enquiry
Good information means a firmer quote. Helpful details to send:
- Any specification or named product
- Your programme or deadline
- Asbestos survey details if the building is older
- A wide shot and a close-up of the area

When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Old mastic that tests positive for asbestos
- Misted, cracked or failed glazing units (a glazier’s job)
- Structural cracks or movement the joints weren’t designed for
If you’re not sure, just phone 01277 525 020 or email us and we will give you a straight answer before you book.
Surfaces we seal
