How we handle commercial sealant contractors in Fernhurst

Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the documents buyers ask for are ready: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. If your site needs RAMS, an insurance certificate or CSCS details, say so and we’ll confirm with the quote. If you’re dealing with layers of sealant, all of them failing and water staining near frames, panels or ceilings, we can put it right, whatever the surface. Searching for sealant specialists in Fernhurst? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

If you look after more than one building near Fernhurst, the work can be planned as one programme, so standards and paperwork match across every site.

Work in smaller places such as Fernhurst tends to come one building at a time: a pub kitchen, a hall, a small office. We’ll want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What the job involves on each surface

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. Proper degreasing comes before any new sealant, with a food-safe or hygienic product wherever food contact can happen.

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. They need a sealant with the right movement capability, laid at the right depth. We confirm the access in place before we quote.

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Fernhurst, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Send details through our quote form, or ask for a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Getting the site ready

  • Confirm the product named in the specification
  • Point out parking and an unloading spot
  • Make sure the joints can be reached

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

After the work

Keep the joints in good shape with a few simple steps:

  • Deal with small splits before they become leaks
  • Look at the sealant around anything that has been moved or replaced
  • Add sealant to the planned maintenance inspection list
  • Check the asbestos register before anyone disturbs old sealant in an older building

Good ventilation keeps wet-area sealant in better condition. Fans that are broken or switched off leave joints damp for longer, which is how mould gets back in. Your maintenance team can look at extract fans at the same time.

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.

What Fernhurst’s businesses ask us to seal

The South East is one of the drier parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. Fernhurst lies roughly 41 miles out from central London. The commuter belt holds a great many offices, retail parks and business parks. If you have premises across the region, one contractor can cover them all.

Occupiers with premises at both Hurstfold Industrial Estate and Kings Road Industrial Estate could have the sealant at each handled under one quote. Offices and shops close to stations such as Haslemere station (to the north of Fernhurst) tend to be busy all day, so sealant work is planned around opening hours.

Fernhurst is about 10 miles east of Petersfield, in West Sussex. Our applicators travel to Fernhurst for work on sealant joints, handled exactly as we handle every other area. Across West Sussex, 373 places are covered, including Fernhurst. We also cover Portsmouth, some 23 miles away.

Do you need commercial sealant contractors in Fernhurst?

Resealing over the top is a false economy we come across often. New silicone has nothing to key into so it soon peels and traps moisture against the joint. By the time it shows, there can be two or three layers to cut out.

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

  • Window and door perimeter joints that have cracked open
  • Hardened, chalky sealant on south-facing or exposed elevations
  • Sanitary sealant that has gone black and patchy
  • Shrunken sealant along kitchen worktops and splashbacks

Industrial estates such as Hurstfold Industrial Estate, 1.3 miles to the south-east of Fernhurst, have offices, trade counters and welfare areas whose sealant ages like any other building’s.

Before you book anyone

  • Their pre-qualification and accreditations
  • Their public liability cover
  • Whether their applicators hold CSCS cards
  • The named product and why it was chosen

How to choose a sealant contractor

When something else is needed

We check first that sealant really is the fix. It won’t put right:

  • Suspect materials that need testing and specialist removal
  • Walls or slabs moving more than any sealant can take
  • Leaks from pipework, wastes or valves (that’s plumbing)

If you are not sure, just call the office on 01277 525 020 or email us and we will give you a straight answer before you book.

Where we work in Fernhurst
