Sealant applicators in Tatsfield

Sometimes a split bead is a symptom rather than the cause. Water at a window perimeter might be coming from the frame, the cill or the wall behind while a movement joint that keeps tearing may simply be too narrow for the job. We look before we quote and tell you plainly if sealant won’t solve it, so nobody pays for a reseal that can’t hold. If you have water staining near frames, panels or ceilings and mouldy silicone around WCs, urinals and vanity tops, we can help, on floor and threshold joints, movement joints in walls and floors and washrooms and tea points alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Tatsfield, that means joint design, primers and backing rod as standard.

A lot of what we do in Tatsfield is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.

Business units in the countryside around places like Tatsfield are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When to call us in Tatsfield

When a bead peels cleanly off one face, it has failed in adhesion. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.

Common reasons buildings call us in:

  • Mouldy silicone around WCs, urinals and vanity tops
  • Weathered facade sealant that no longer flexes
  • Movement joints packed with grit and debris
  • Greasy, split joints in a kitchen or tea point

Trade counters and showrooms on estates such as Biggin Hill Airport Trading Estate (1.8 miles north of Tatsfield) need neat joints where customers see them.

Multi-site occupiers here often want one sealant contractor across all their buildings. Several hotels sit less than 2 miles from Tatsfield.

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Keep a record of which joints were resealed and when
  • Deal with small splits before they become leaks
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Ask fit-out and M&E contractors to report any sealant they disturb

Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks, with external elevations and wet areas first in line. If anything looks wrong, ring 01277 525 020 or email a schedule or drawings with a photo.

Sealant rarely fails all at once across a building. The first failures are often a warning about the rest. We can assess the lot and suggest what to do now and later.

Our process

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks, and we clear our waste as we work. Rural sites near Tatsfield may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  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. Completed areas are signed off with you under our 12-month guarantee.

Preparing the site

  • Tell us which areas need to stay in use
  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions

Advice

Why it’s worth doing now in Tatsfield

Patching the worst lengths can be the right call on a tight budget. If the rest of the bead is the same age and product, though, it’s usually close behind, so access and set-up end up being paid for twice. We can price both options so you can decide on the facts. One visit to deal with every failing joint makes more sense than several trips to a place like Tatsfield, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What you get with us

How the job changes by surface

Movement joints in walls and floors

Movement joints in walls and floors let the structure expand and contract. When the seal fails, debris gets in and the joint stops working. The new sealant is chosen for the movement and, on floors, the traffic.

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.

Questions about Tatsfield

Is Biggin Hill Airport Trading Estate, near Tatsfield, within your area?

Yes, sites like Biggin Hill Airport Trading Estate are within our area, along with the rest of Tatsfield. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.

Is Tatsfield off your patch?

Not at all. Tatsfield is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited and a Constructionline member.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Does commercial sealant work come with a guarantee?

The work is guaranteed for 12 months. Should a joint we sealed give trouble during those 12 months, let us know and we’ll look at it.

Can areas stay open during the work?

That comes down to planning: we agree access windows, phase the work and keep enough facilities open. Tell us what has to stay open and we will plan the job around it.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Cost factors for sealant joints

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Whether the work must be split into stages
  • The size and state of each joint
  • Site requirements such as inductions and permits
  • Distance, for remote addresses

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • Whether an asbestos survey exists
  • Photos of the joints, close up and from further back
  • Whether the building will be occupied during the work
  • The site address and postcode

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
