Commercial mastic work in Flacks Green

Most of the buildings we seal stay open while we are there. Work is scheduled around the site hours and access windows you give us; phasing keeps some washrooms, kitchens or entrances available while others are done. That applies whether the building is an office, a shop, a hotel, a college or a care home. Most enquiries involve sanitary sealant that has gone black and patchy and gaps behind commercial kitchen worktops and sinks, on movement joints in walls and floors, external facade joints and kitchen worktops and splashbacks. Searching for sealant specialists in Flacks Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

A lot of what we do in Flacks Green 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 Flacks Green, the commercial buildings we’re 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.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Commercial premises in Flacks Green

Central London is about 35 miles from Flacks Green. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Occupiers with several premises in the region tend to prefer one contractor and one point of contact. Flacks Green 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.

Premises within reach of Hatfield Peverel station (to the south-east of Flacks Green) often have busy frontages where joints are seen by everyone passing. If you run an office at a site such as Banters Lane Business Park, which lies north-west of Flacks Green, the sealant at reception desks, tea points and frames ages with each fit-out.

Different surfaces, different methods

Commercial kitchens and tea points

A smooth, continuous joint is easier to keep clean. We seal to a neat, cleanable finish and work around service times you agree with us.

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. The design and sign-off of fire stopping belong to the designer and building control, and we install to the specification.

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • Joint width, depth and condition
  • Any access equipment needed
  • Travel to remote or island sites
  • Whether old sealant has to be cut out first

A quote for sealant joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • Where the site is, with the postcode
  • Anything awkward about access or site hours
  • Rough lengths or quantities, or drawings if you have them
  • Your programme or deadline

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Have extract fans checked so wet areas dry out
  • Keep abrasive pads and scrapers off resealed joints
  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Keep barriers up until the new sealant has cured

Good ventilation keeps wet-area sealant in better condition. Fans that are broken or switched off leave joints damp for longer, and mould follows damp. It’s worth having fans checked while the sealant is fresh.

Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Replacing it on a planned cycle keeps complaints down.

Building owners, agents and FMs in Flacks Green

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

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Leave it or put it right?

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. Halls, stores and units around places like Flacks Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
