Construction mastic near Guilton

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

When you manage a building on behalf of an owner, 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, plus a 12-month guarantee.

How we handle construction mastic in Guilton

On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. The enquiries we see most involve inconsistent sealant finishes from plot to plot and bath and shower joints scraped during the final clean, on window and door perimeters, cladding and panel joints and sanitary and kitchen joints. Facilities teams, main contractors and managing agents in Guilton tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Guilton, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

From enquiry to sign-off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a building around Guilton, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We walk the site or review drawings to understand the package.
  2. You receive a fixed quote covering scope, products and sequence.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Problems we find, such as oversized gaps, are raised straight away.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

Getting the site ready

  • Point out any areas we must not close
  • Move anything stored against the joints
  • Tell us your opening times and when work is allowed

Related advice

General trades versus a specialist

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Common questions from Guilton clients

Can the mastic package for our job in Guilton follow the site programme?

Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is Guilton off your patch?

Not at all. Guilton is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can you fit around our programme?

Our work is sequenced around the programme. Areas are sealed as they’re released by the site team.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

What’s the quickest route to a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

How the job changes by surface

Bathrooms, en suites and washrooms

Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent, plot by plot or floor by floor.

Window and door perimeters

Gaps around frames have to be within the sealant’s range. Gaps outside the product’s range are raised with the site team.

Facades, frames and programmes in Guilton

Guilton is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. Guilton is about 61 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

Hotels like The Lion Hotel (to the east of Guilton) rarely close for long, so refurbishment mastic is phased floor by floor. For contractors refurbishing units at places like Birnham Farm Business Centre, which lies south-east of Guilton, the mastic covers cladding panels, roller-door and window perimeters. School extensions, at buildings such as Ash Cartwright and Kelsey Church of England Primary School, typically run to the summer holidays, mastic included.

Guilton is about 7 miles north-west of Deal, in Kent. Anywhere in CT3, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Guilton is one of 931 places in Kent on our list for mastic packages. We also cover London, around 61 miles from Guilton.

Business premises anywhere in CT3 are within our area for mastic packages. Among the streets we cover are Guilton, Durlock Road and Poulton Lane, and sites on any of them can send details for a fixed quote.

When it isn’t the sealant

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Approving fire stopping as compliant
  • Designing joint widths or choosing the specification (that sits with the designer)
  • Frame gaps too wide for sealant, which the installer needs to correct

If you’re not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Quoting for work in Guilton

A fixed quote reflects the actual work. It takes account of:

  • Access and working height
  • Travel to remote or island sites
  • Site requirements such as inductions and permits
  • How much existing material needs removing

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Sending details for a quote

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Any dates the work must fit around
  • The product your specification calls for
  • Rough lengths or quantities, or drawings if you have them
  • How the joints are reached, and at what height

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or email drawings and photos.
