Sealant applicators in St Michaels

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and in an occupied building failure typically 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 St Michaels. 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 frame mastic that has hardened and come away from the wall and wall and floor joints that have lost their seal, on external facade joints, floor and threshold joints and kitchen worktops and splashbacks. A single leaking joint is often how a building in St Michaels first comes to us: we look at the rest while we are there and tell you what we find.

We price commercial jobs in St Michaels from photos, drawings or a site visit, and the scope is set out in writing.

Commercial sealant work around smaller places like St Michaels tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Different surfaces, different methods

Fire-rated seals where specified

Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. The design and sign-off of fire stopping belong to the designer and building control, and we install to the specification.

Shop fronts and retail fit-outs

In retail, sealant is on show. Joints around counters, displays and shopfront frames have to look tidy as well as seal. Colour options are confirmed with the quote.

How the quote is worked out

We price every job individually. The main factors are:

  • Location, for remote and island sites
  • Quantities, in metres or numbers
  • The size and state of each joint
  • Removal of failed or old sealant

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What to include in your enquiry

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • A wide shot and a close-up of the area
  • The type of building and who uses it
  • How the joints are reached, and at what height
  • The asbestos register, for older buildings

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

How a job runs

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before the next one starts. For a building around St Michaels, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. First, details reach us through the quote form or 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. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Before we start on site

  • Send any specification or drawings in advance
  • Point out any areas we must not close
  • Warn occupants and staff about the work

Advice

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

When to call us in St Michaels

If sealant tears through its centre, it has failed cohesively. Typically the movement was too much for the sealant chosen: 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.

What tends to prompt an enquiry:

  • Damp patches where an external joint has failed
  • Frame sealant that has cracked, shrunk or pulled away
  • Mouldy silicone around WCs, urinals and vanity tops
  • Smeared sealant across finishes from a rushed job

On a business park such as Business Park, 2 miles to the west of St Michaels, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.

Questions to ask before you book

  • Proof of insurance
  • Which product they’ll use, and why it suits the joint
  • How the joint faces will be prepared and primed
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

When to bring in a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Questions we’re asked in St Michaels

Is St Michaels too far out for you?

No. Places such as St Michaels are covered as much as the big towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Does a hotel in St Michaels need to shut while its sealant is renewed?

In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

What guarantee do you give on resealing?

Our workmanship on each job is backed by a 12-month guarantee. We are fully insured for public liability as well.

Can you supply RAMS and insurance details?

We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.

Can one contractor look after sealant on all our buildings?

Yes. We take on runs of jobs across portfolios as well as single sites, priced site by site or as one programme.

Sealant on show in St Michaels’s commercial buildings

The South East is one of the drier parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings. Central London is about 45 miles from St Michaels. The commuter belt holds a great many offices, retail parks and business parks. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

In hotels such as Little Silver Country Hotel, which lies north-west of St Michaels, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. Occupiers with premises at both Business Park and Pickhill Business Centre could have the sealant at each handled under one quote.
