How the job changes by surface

Facade and cladding joints

Facade sealant failures can be hard to spot from the ground. Close-up photos or a site visit tell us what’s needed, with colours confirmed for the product chosen.

Commercial kitchens and tea points

Gaps and ragged beads trap dirt that cleaning can’t reach, and cleanability is part of what an inspector looks at. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.

Failed sealant isn’t always the whole story. Water at a window perimeter might be coming from the frame, the cill or the wall behind, and repeated splits in a movement joint can mean the joint is too narrow for the movement. Part of the job is telling you when the fix is something other than sealant, so nobody pays for a reseal that can’t hold. The enquiries we see most involve greasy, split joints in a kitchen or tea point and leaks that seem to come through a sealant line, across washrooms and tea points, floor and threshold joints and external facade joints. A single leaking joint is often how a building in Wendlebury first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

A lot of what we do in Wendlebury 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 Wendlebury are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

What sets the cost

We price every job individually. The main factors are:

  • The product specified
  • Backing rod, priming and other preparation
  • Travel to remote or island sites
  • How accessible the joints are

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Details that help us quote

Good information means a firmer quote. When you get in touch, include:

  • What the building is and how it’s used
  • Anything awkward about access or site hours
  • Approximate linear metres or a joint schedule
  • When you need the work done

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Common problems we fix in Wendlebury

When a bead peels cleanly off one face, it has failed in adhesion. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. It’s one of the commonest faults we find on earlier work.

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

  • Untidy joints in a reception, shop floor or lobby
  • Gaps behind commercial kitchen worktops and sinks
  • Weathered facade sealant that no longer flexes
  • Expansion joints with the sealant torn out

For a retailer at a site such as Bicester Shopping Park (1.7 miles north-east of Wendlebury), the joints customers see are as much part of the fit-out as the shelving.

Comparing quotes

  • What level of public liability insurance do they hold?
  • Will CSCS-carded applicators be on site?
  • Which product they’ll use, and why it suits the joint
  • Are they CHAS accredited or on Constructionline?

Our contractor checklist

Aftercare for building managers

Regular inspection catches problems early. In particular:

  • Keep washroom and kitchen extraction working
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Add sealant to the planned maintenance inspection list
  • Check joints after other trades have worked nearby

Add the resealed joints to your planned maintenance inspections. A periodic look catches splits and lifting edges early, with external elevations and wet areas first in line. If anything looks wrong, give us a call on 01277 525 020 or email a schedule or drawings with a photo.

In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Environmental health officers look at how cleanable surfaces are, so sound, smooth joints matter.

Questions about Wendlebury

Does your area include sites such as Bicester Shopping Park, near Wendlebury?

Yes, sites like Bicester Shopping Park are within our area, along with the rest of Wendlebury. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Is Wendlebury off your patch?

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.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Will the building have to shut during the work?

It’s normal for us to work in occupied buildings. Only the area being sealed is closed, and the sequence is agreed in advance, until its cure time has passed.

How long does a typical visit take?

That varies with the scale of the job, 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. For bigger or phased jobs, we’ll set out a timescale with the quote.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

What about asbestos in old mastic?

On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder.

What happens if it’s left?

A cheaper quote sometimes means the old bead stays in. Sealing over looks tidy at handover, then lifts once the joint starts moving. Every quote we give includes full removal and preparation. One visit to deal with every failing joint makes more sense than several trips to a place like Wendlebury. Photos of every joint help us quote for the whole job.

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Why appoint us

  • Our applicators hold CSCS cards
  • A Constructionline member, so easy to vet
  • One number for every site we cover
  • Fully insured

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near Wendlebury need work, visits can be combined. A fixed quote is given before anything starts.

  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. The failed sealant comes out and the faces are prepared, with primer where required.
  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.

What we need from you

  • Move anything stored against the joints
  • Let us know about inductions and permits
  • Point out parking and an unloading spot

Get a fixed quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Refits at hotels like Bicester Hotel Golf and Spa, 1.2 miles to the north-west of Wendlebury, bring joints at vanity tops, bars and reception desks that guests see every day.
