Sealant applicators in Leysdown-on-Sea

How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed, then both faces are cleaned back to sound, dry material with no dust or grease on them. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead, and a backing rod limits the depth to give the sealant room to work. We work on external facade joints, window and door perimeters and washrooms and tea points, and what we are called in for most is untidy joints in a reception, shop floor or lobby and hardened, chalky sealant on south-facing or exposed elevations. Whoever orders the work in Leysdown-on-Sea, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

On a typical commercial building in Leysdown-on-Sea, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.

Work in smaller places such as Leysdown-on-Sea tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Suspect materials that need testing and specialist removal
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Faulty windows rather than failed perimeter sealant

If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Surfaces we seal

  • Kitchen worktops and splashbacks
  • Movement joints in walls and floors
  • Window and door perimeters
  • Floor and threshold joints
  • External facade joints
  • Washrooms and tea points

Questions about Leysdown-on-Sea

Is Leysdown-on-Sea too far out for you?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can the sealant on our Leysdown-on-Sea premises match the finishes?

Yes, we can normally get close to most finishes from the product’s colour range. The quote lists the colours the product is made in.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

How do we get a quote?

Photos, drawings or a schedule of the joints are typically enough to start through our quote form. If a visit is needed we’ll book one, and a fixed quote follows.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes anything from part of a day on a short run of joints to several weeks on a large phased package. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Will the building have to shut during the work?

Most of the buildings we work in stay occupied. Only the area being sealed is closed, and the sequence is agreed in advance, until its cure time has passed.

General trades versus a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For managing agents and facilities managers

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Our process

Diagnose, treat, 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. Rural sites near Leysdown-on-Sea may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Let building users know which areas are affected
  • Confirm the product named in the specification
  • For older buildings, check the asbestos register before work

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

What sets the cost

Your fixed quote is built from the real scope. It takes account of:

  • Site requirements such as inductions and permits
  • Phasing around occupants
  • Removal of failed or old sealant
  • Distance, for remote addresses

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Send us:

  • Any specification or named product
  • What the building is and how it’s used
  • How the joints are reached, and at what height
  • Approximate linear metres or a joint schedule

For a fixed quote, phone 01277 525 020 or email us with the site address and an outline of the work. You can also send details through our quote form.

Commercial kitchens and tea points

Shop fronts and retail fit-outs

Shop fits put sealant right in front of clients. Counters, display units, shopfront frames and floor trims all need a neat line. Colour options are confirmed with the quote.
