Sealant specialists in Highleigh

Failed sealant isn’t always the whole story. A leak near a frame edge can start in the frame, the cill or the cavity, 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. If you have wall and floor joints that have lost their seal and black mould through washroom sealant that won’t clean off, we can help, on external facade joints, washrooms and tea points and window and door perimeters alike. A single leaking joint is often how a building in Highleigh first comes to us: we look at the rest while we are there and tell you what we find.

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

In and around smaller places such as Highleigh, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Owners, agents and contractors

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Highleigh can sit alongside others in a wider programme across West Sussex.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Don’t let cleaning or traffic back on before the cure time is up
  • Put external and wet-area joints on a regular inspection round
  • Keep a record of which joints were resealed and when

Give fresh sealant time to cure before it’s cleaned, wetted or walked past. That time depends on the product, the temperature and the joint depth, and we confirm it when each area is handed back. Leaving the area closed until then keeps the bead neat.

Sealant installed at the same time typically fails in sequence. A few splits this year normally mean more next year, so it makes sense to look at the wider elevation or block. We’ll tell you which sealant joints need doing first and which can wait.

What Highleigh’s businesses ask us to seal

Highleigh lies within about 2 miles of the sea. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. A matched colour is only half the brief on an exposed frontage. Highleigh lies roughly 59 miles out from central London. Business parks and retail centres are common around the capital’s motorway corridors. If you have premises across the region, one contractor can cover them all.

Occupiers with premises at both Enborne Business Park and Ferry Yard Industrial Park could have the sealant at each handled under one quote. Premises within reach of Chichester station (3.9 miles north of Highleigh) often have busy frontages where joints are seen by everyone passing. For tenants and agents on sites such as Enborne Business Park, 1.2 miles to the south-east of Highleigh, office fit-outs, reception joints and window perimeters are the usual sealant work.

Highleigh is about 3 miles north of Selsey, in West Sussex. We cover commercial sites throughout Highleigh, whether it’s a single job or part of a planned programme. Across West Sussex, 373 places are covered, Highleigh among them. Portsmouth is covered too, around 12 miles from Highleigh.

If you need commercial sealant contractors in PO20, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Streets here include Critchel's Lane, Highleigh Road and Green Lane. We also cover Almodington (1 mile west), Birdham (2 miles north-west), Somerley (2 miles west), Earnley (2 miles west) and Shipton Green (3 miles north-west). Further afield, our area takes in Bognor Regis (5 miles east), Chichester (4 miles north), Selsey (3 miles south), Littlehampton (12 miles east), Rustington (13 miles east) and Angmering (15 miles east).

Your questions answered

Is Highleigh too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Can you work at a site such as Enborne Business Park, by Highleigh?

Yes, sites like Enborne Business Park are within our area, along with the rest of Highleigh. Photos and a short description are enough for a first look.

How many days will you need on site?

That varies with the scale of the job, but the work typically 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.

Can you take on work for an FM or managing agent?

Yes. You can send details through our quote form.

Could the old sealant in an older building contain asbestos?

In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. Before cutting anything out, we ask for the asbestos register or survey, and anything suspect is left until it has been tested.

Can you handle sealant work across several sites?

Yes. We regularly take on multi-site work and planned maintenance programmes.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

Our process

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Rural sites near Highleigh may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. First, details come to us: photographs, drawings or a schedule of the areas.
  2. Next comes a diagnosis and a fixed quote.
  3. Before anything is cut out, we agree access, timings and sequence.
  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. Each area is inspected, signed off and backed by our 12-month guarantee.

What we need from you

  • Move anything stored against the joints
  • Tell us your opening times and when work is allowed
  • Tell us what induction or permit system the site runs

Advice

Leave it or put it right?

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 normally close behind, so access and set-up end up being paid for twice. Where it helps, we quote a patch and a full reseal side by side. One visit to deal with every failing joint makes more sense than several trips to a place like Highleigh, rather than one at a time. Send photos of each area and we will quote for the lot.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Quoting for work in Highleigh

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Travel to remote or island sites
  • How accessible the joints are
  • Which sealant the job calls for
  • How much there is to seal

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

What to include in your enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Any specification or named product
  • What the building is and how it’s used
  • The postcode of the building
  • How the joints are reached, and at what height

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. If you have questions first, give us a call on 01277 525 020 or use the quote form.

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Suspect materials that need testing and specialist removal
  • Misted, cracked or failed glazing units (a glazier’s job)
  • Walls or slabs moving more than any sealant can take

If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think.

Joints and surfaces we work on
