About our commercial sealant contractors in Leverton

Commercial occupiers rarely want a floor out of action for sealant work. Tell us your site hours and access windows and we’ll plan around them. That applies whether the building is an office, a shop, a hotel, a college or a care home. Most enquiries involve leaks that seem to come through a sealant line and wall and floor joints that have lost their seal, on window and door perimeters, external facade joints and floor and threshold joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Leverton it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

A lot of what we do in Leverton is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Rural business units near smaller places such as Leverton are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.

Our workmanship is guaranteed for 12 months, in Leverton as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

From enquiry to sign-off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a few hours to several days on most single sites, depending on joint lengths and access, and we clear our waste as we work. Smaller jobs around Leverton can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. You send photos, drawings or a list of the joints and areas involved.
  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. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Have the specification and drawings to hand
  • Arrange parking or a loading space

Related advice

Why deal with it now?

It can be tempting to hold sealant work back until the next refurbishment. That’s reasonable for internal joints that are just tired-looking, but external and wet-area joints that already leak shouldn’t wait. We can seal the urgent joints now and leave the rest for the programme. One visit to deal with every failing joint makes more sense than several trips to a place like Leverton. Send photographs of each area and we will quote for the lot.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why appoint us

  • Work carried out by CSCS-carded applicators
  • Fully insured, including public liability cover
  • Colour agreed before work starts
  • Standard and matched colours in many product ranges

Take a look at how commercial sealant jobs are priced or our accreditations.

What sets the cost

Quotes vary with the job. It mainly depends on:

  • Site requirements such as inductions and permits
  • The total length or number of joints
  • Distance, for remote addresses
  • Joint width, depth and condition

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.

What to include in your enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Access details, including height
  • Clear photographs of the problem areas
  • Whether the building will be occupied during the work
  • Where the site is, with the postcode

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or email us.

Different surfaces, different methods

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, in a shade that suits the frame.

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. The choice comes down to how much the joint moves and what runs over it, and tell you if the edges need repairing first.

Questions we are asked in Leverton

Do hotels near Leverton have to close for sealant work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.

Is Leverton too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you work for facilities managers and managing agents?

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’ll fit in.

Is it OK to apply fresh sealant over existing beads?

The old bead is stripped out first. After that come cleaning, primer where needed, backing and the new sealant.

Can areas stay open during the work?

That comes down to planning: we agree access windows, phase the work and keep enough facilities open. Let us know what can’t close and we’ll work around it.

Does the weather affect the 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. Indoors, the weather is rarely a problem.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Sealant on show in Leverton’s commercial buildings

Leverton has at least three named business or industrial parks inside a 3-mile radius. Sites like these see regular refits, with shopfronts, offices and staff areas to seal. Leverton lies roughly 62 miles out from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Firms with branches across the South East can use one contractor for every site.

If you have premises on more than one site, say at Charnham Business Park and Hungerford Trading Estate, one contractor and one quote can cover both. Parks like Charnham Business Park (to the south-east of Leverton) see tenants come and go, and every move-in brings joints to seal.

Leverton is about 9 miles west of Newbury, in West Berkshire. Commercial clients in Leverton can call on us for sealant joints. 140 places across West Berkshire fall within our area, including Leverton. For work in that direction, see our Reading page (24 miles or so).

Work on sealant joints is covered throughout RG17. Nearby places we also cover include Chilton Foliat (1 mile north-west), Upper Eddington (1 mile south-east), Eddington (1 mile south-east), Hungerford (1 mile south) and Woodlands St Mary (3 miles north). A short drive away, we cover Newbury (9 miles east), Thatcham (12 miles east), Speenhamland (9 miles east), Lambourn (5 miles north), Shaw (9 miles east) and Wash Common (9 miles south-east).

Maintenance after handover

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

  • Keep abrasive pads and scrapers off resealed joints
  • Keep washroom and kitchen extraction working
  • Check sealant as part of routine building inspections
  • Check the asbestos register before anyone disturbs old sealant in an older building

Our workmanship on each job is backed by a 12-month guarantee. Keep the handover details with your O&M or maintenance records, and tell us if a joint we sealed gives trouble within that time.

Sealant rarely fails all at once across a building. A few splits this year usually mean more next year so the whole run is worth inspecting. We can assess the lot and suggest what to do now and later.

Signs you need commercial sealant contractors in Leverton

A good share of the joints we inspect were topped up instead of being renewed. Fresh sealant won’t stick to the old bead underneath so it soon peels and traps moisture against the joint. Getting back to a clean joint then means removing every layer.

Look out for the following:

  • Black mould through washroom sealant that won’t clean off
  • Gaps behind commercial kitchen worktops and sinks
  • A top-up bead over failed sealant, now lifting
  • Leaks that seem to come through a sealant line

In hotels such as The Bear Hotel, which lies south-east of Leverton, refurbishments normally mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

What your quote should include

  • Do they follow the manufacturer’s priming guidance?
  • Can the work be phased to keep areas open?
  • Will CSCS-carded applicators be on site?
  • The named product and why it was chosen
