Commercial sealant contractors for Earnley sites

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

After the work

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

  • Look at the sealant around anything that has been moved or replaced
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Make sure ventilation in wet areas is switched on and working
  • Keep barriers up until the new sealant has cured

In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, which is how mould gets back in. It’s worth having fans checked while the sealant is fresh.

Tenants and staff spot black or split sealant quickly, and in a hotel, office or shop it makes the whole space look neglected. Planned replacement saves fielding the same complaint again and again.

Commercial mastic work in Earnley

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and in an occupied building failure normally announces itself as a stained ceiling or an unhappy tenant. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors with sites in Earnley. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. Site teams most often ask us about wall and floor joints that have lost their seal and leaks that seem to come through a sealant line, on washrooms and tea points, floor and threshold joints and movement joints in walls and floors. A single leaking joint is often how a building in Earnley 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.

In an occupied building in Earnley, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.

Rural business units near smaller places such as Earnley are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Commercial clients in Earnley

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Earnley may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Preparing the site

  • Move anything stored against the joints
  • Send any specification or drawings in advance
  • Send your site hours and access windows

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or send details through our quote form.

Shops, offices and hotels in and around Earnley

Earnley is within about 2 miles of the coast. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. We choose a product rated for the exposure, then confirm the colours available for it. Earnley is in the South East, one of the UK’s drier regions. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.

On a business park such as Enborne Business Park, 2.5 miles east of Earnley, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.

Earnley is about 3 miles north-west of Selsey, in West Sussex. Looking for commercial sealant contractors in Earnley? We can help, as we do across West Sussex. We work across 373 places in West Sussex, large and small. Portsmouth is covered too, some 11 miles away.

When to call us in Earnley

If sealant tears through its centre, it has failed cohesively. That usually means the joint stretched further than the product could cope with: 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.

Common reasons buildings call us in:

  • Water staining near frames, panels or ceilings
  • Gaps behind commercial kitchen worktops and sinks
  • A top-up bead over failed sealant, now lifting
  • Frame sealant that has cracked, shrunk or pulled away

If you have premises on more than one site, say at Enborne Business Park and Ferry Yard Industrial Park, one contractor and one quote can cover both.

Our contractor checklist

Why act early in Earnley

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. Often the fitting is sound and the joint is the only thing letting it down. A careful reseal is a far smaller undertaking than replacement. Around Earnley, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

What you get with us

  • One phone line for London, the South East and Scotland
  • Coloured sealants to suit the setting, where available

Honest limits

Some faults sit outside our scope, and we say so rather than covering them up:

  • Cracking that needs a structural engineer to look at it
  • Suspect materials that need testing and specialist removal
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)

Not sure which it is? You can phone 01277 525 020 or send photos by email and we will tell you honestly.

Surfaces we seal

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

How long before the joints can be used?
