Commercial sealant contractors for commercial buildings in Frant

How long a joint lasts is decided before any sealant leaves the gun. Silicone has no grip on cured silicone, so the failed bead is cut out completely and the faces are cleaned until they’re sound and dry, with no dust or grease left. Primer is used wherever the manufacturer calls for it on that surface. We work on external facade joints, window and door perimeters and kitchen worktops and splashbacks, and the failures we’re asked to look at most are smeared sealant across finishes from a rushed job and greasy, split joints in a kitchen or tea point. A specialist sealant contractor works differently from a general builder: on jobs in Frant, preparation and product choice get the time they need.

The most common commercial job in Frant is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.

Work in smaller places such as Frant 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.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Aftercare for building managers

After handover, a little attention goes a long way:

  • Keep a record of which joints were resealed and when
  • On pre-2000 buildings, share the asbestos information before work starts
  • Check sealant as part of routine building inspections
  • Have extract fans checked so wet areas dry out

Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.

Tenants and staff spot black or split sealant quickly, and it reflects on how the building is run. Planned replacement saves fielding the same complaint again and again.

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Frant can form part of a wider programme.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Why act early in Frant

Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Our prices always include removal of the failed bead and full joint preparation, because that’s what makes the new bead last. One visit to deal with every failing joint makes more sense than several trips to a place like Frant. Photos of every joint help us quote for the whole job.

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why choose Mastic Doctor in Frant

  • Health and safety: CHAS accredited
  • 12 months’ guarantee on every job
  • Joints cleaned back to sound surfaces
  • RAL and finish matching where the product range allows

Common questions from Frant clients

Is a smaller place like Frant outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Will you take on work at estates like Royal Victoria Shopping Centre, close to Frant?

Yes. Our area takes in Frant and its surroundings, with estates and business parks such as Royal Victoria Shopping Centre included. To start, just speak to us on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Can you handle sealant work across several sites?

Yes, within the areas we cover: South East England, Greater London and Scotland. One contact and one process for every building makes a portfolio easier to manage.

Is failed sealant stripped out, or sealed over?

Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.

How long does a job like this take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Which site documents can you send us?

Send your site requirements with the enquiry, and we’ll confirm the RAMS, insurance and CSCS details with the quote. From you, we’ll need the asbestos information for older buildings and any site rules.

Working on commercial sites near Frant

Frant sits in one of the drier corners of the country, the South East. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. At about 32 miles from central London, Frant is within reach of the capital. 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.

Offices and shops close to stations such as Frant station (to the north-east of Frant) tend to be busy all day, so sealant work is planned around opening hours. Refits at hotels like The Abergavenny Arms Hotel, less than half a mile north-west of Frant, bring joints at vanity tops, bars and reception desks that guests see every day. If you look after units at a retail site such as Royal Victoria Shopping Centre, 2.7 miles to the north of Frant, shopfront perimeters and shop-fit joints are where a matched colour shows.

Frant is about 3 miles south of Royal Tunbridge Wells, in East Sussex. We cover Frant and the rest of East Sussex, with the same fixed quotes and 12-month guarantee as everywhere else. 308 places across East Sussex fall within our area, including Frant.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Old mastic that tests positive for asbestos
  • Faulty windows rather than failed perimeter sealant
  • Structural cracks or movement the joints weren’t designed for

Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

What we seal

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

From enquiry to sign-off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks, and our waste is bagged and taken away as we go. If others near Frant need work, visits can be combined. A fixed quote is given before anything starts.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. Completed areas are signed off with you under our 12-month guarantee.

What we need from you

  • Flag any permit to work we will need
  • Share the asbestos register for older buildings
  • Point out any areas we must not close
