Commercial sealant contractors near Five Oaks

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • A dripping trap, valve or pipe behind a fitting
  • Structural cracks or movement the joints weren’t designed for
  • Old mastic that tests positive for asbestos

If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think before you book.

What we seal

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

Commercial sealant contractors for commercial buildings in Five Oaks

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before old sealant is disturbed. Anything suspect is left alone until it has been tested, and we don’t remove asbestos-containing materials ourselves. We work on kitchen worktops and splashbacks, washrooms and tea points and movement joints in walls and floors, and the failures we’re asked to look at most are weathered facade sealant that no longer flexes and damp patches where an external joint has failed. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Five Oaks, that means joint design, primers and backing rod as standard.

The most common commercial job in Five Oaks is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

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

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

From enquiry to sign-off

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For work around Five Oaks, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First, details come to us: photographs, drawings or a schedule of the areas, or we arrange a site visit.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. We strip the failed bead and prepare both faces of the joint.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Move anything stored against the joints
  • Agree which areas must stay open

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; we install what’s specified.

Washrooms and toilets

Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone.

Common problems we fix in Five Oaks

If sealant tears through its centre, it has failed cohesively. Typically the movement was too much for the sealant chosen: a bead laid too thin, an over-stretched joint or the wrong movement class. The same product in the same joint tends to fail the same way.

Any of the following is a good reason to get the joints checked over:

  • Sanitary sealant that has gone black and patchy
  • Expansion joints with the sealant torn out
  • Greasy, split joints in a kitchen or tea point
  • Frame sealant that has cracked, shrunk or pulled away

A unit on an estate like Billingshurst Trade Park (to the south-west of Five Oaks) usually has an office front, a trade counter and staff facilities with joints of their own.

Questions to ask before you book

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How they’ll work around occupants
  • Their pre-qualification and accreditations
  • Their public liability cover

How to choose a sealant contractor

FAQs: Five Oaks

Is Five Oaks off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you offer colour-matched sealant for buildings in Five Oaks?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can you work to our specification?

Yes. Send it with your enquiry, and we will price the work to it.

Which site documents can you send us?

Let us know your requirements when you ask for a price, and the paperwork is confirmed with the quote. For older buildings we’ll ask for the asbestos register, plus your site induction rules.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

What affects the price in Five Oaks

These are the things that shape the price:

  • Site requirements such as inductions and permits
  • Backing rod, priming and other preparation
  • Whether the work must be split into stages
  • Travel to remote or island sites

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.

Sending details for a quote

We can often quote from photographs and a few details. Please tell us:

  • The asbestos register, for older buildings
  • Clear photographs of the problem areas
  • Whether the building will be occupied during the work
  • Specification clauses that apply

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
