Your questions answered

Can the sealant on our Hareplain premises match the finishes?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Available colours for the product are confirmed with the quote.

Is a smaller place like Hareplain outside your area?

Not at all. Hareplain is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

How long does a typical visit take?

That varies with the scale of the job, but the work normally takes a day for a modest shop fit, and longer for a full building or several floors. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Coloured sealant in Hareplain

Colour-matched joints are often among the last items before handover. We work around other trades and protect adjacent finishes, and snag any marks before we leave. Our workmanship carries a 12-month guarantee. If you have dirty, discoloured joints in public areas and patch repairs in several different colours, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Hareplain it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In and around smaller places such as Hareplain, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

After the work

After handover, these steps help:

  • Put the colour reference on the finishes schedule
  • Standardise colours across a portfolio
  • Keep the colour details for future repairs
  • Clean coloured joints with mild products

Keep a record of the product and colour reference used. It makes matching later repairs much easier, with no guesswork.

Approve a sample where colour really matters. Seeing the cured colour in place avoids surprises.

On site: what to expect

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. If others near Hareplain need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. The sealant type is chosen for the joint first, then the colour.
  2. Colour references, samples or photographs of the finish are checked against the product’s range.
  3. Where colour is critical, a sample bead can be agreed in a discreet spot.
  4. We take out the existing bead, clean the joints and fit backing.
  5. We apply the agreed colour and tool it neatly, with masking where the finish needs it.

Preparing the site

  • Send your site hours and access windows
  • Warn occupants and staff about the work
  • Move anything stored against the joints

Getting a fixed quote

What Hareplain’s businesses ask us to seal

Central London is about 40 miles from Hareplain. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. If you have premises across the region, one contractor can cover them all. Hareplain sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

For premises near Headcorn station, 2.8 miles north of Hareplain, footfall is part of the plan: work is phased so shops and offices keep trading. For any commercial premises in Hareplain, a lasting joint depends on full removal of the old sealant and clean, dry faces.

Hareplain is about 10 miles south of Maidstone, in Kent. Our applicators travel to Hareplain for work on colour-matched joints. We work across 931 places in Kent. There’s a separate page for Brighton, about 38 miles away.

Why act early in Hareplain

Resealing a full run gives a consistent colour. Piecemeal repairs over several years tend to drift in colour, and the patchwork effect grows. One visit to deal with every failing joint makes more sense than several trips to a place like Hareplain, rather than one at a time. Photos of every joint help us quote for the whole job.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why appoint us

  • Sealing commercial buildings since 2005
  • Our applicators hold CSCS cards
  • Products installed to the manufacturer’s instructions
  • Colours confirmed for the specified product

For managing agents and facilities managers

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Hareplain. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Hareplain can sit alongside others in a wider programme.

What affects the price in Hareplain

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • The site’s rules and procedures
  • Joint width, depth and condition
  • Removal of failed or old sealant
  • Specialist products, such as fire-rated or hygienic sealants

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

Details that help us quote

A good diagnosis starts with the right details. Let us know:

  • Drawings or a marked-up plan, if available
  • How the joints are reached, and at what height
  • Any dates the work must fit around
  • The asbestos register, for older buildings

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to phone 01277 525 020 or use the quote form.

Doing it in-house

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 easy to get wrong without experience.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
