Construction mastic across Church Whitfield

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

Your questions answered

Can you work around term dates at a campus such as East Kent College?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Church Whitfield off your patch?

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

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. 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. We don’t remove asbestos-containing materials.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How we handle construction mastic in Church Whitfield

On refurbishments, the mastic package typically includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. We work on floor and skirting junctions, sanitary and kitchen joints and cladding and panel joints, and the failures we’re asked to look at most are cracks opening in caulked internal joints and perimeter gaps outside the sealant’s range. Searching for sealant specialists in Church Whitfield? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Around smaller places like Church Whitfield, building work usually 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. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Leave it or put it right?

A quick bead over a damaged joint can get an area past inspection, but it won’t last. New sealant laid on old or dirty sealant has nothing to bond to. We cut out and redo the joint properly. Around Church Whitfield, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Why appoint us

  • Work carried out by CSCS-carded applicators

  • Colour options checked against the specified product
  • 12-month guarantee on workmanship

Take a look at how commercial sealant jobs are priced or our accreditations.

How the quote is worked out

These are the things that shape the price:

  • Travel to remote or island sites
  • Induction, permit and paperwork requirements
  • The total length or number of joints
  • Working within restricted access windows

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Send us:

  • Drawings or a marked-up plan, if available
  • A wide shot and a close-up of the area
  • Any dates the work must fit around
  • Whether the building will be occupied during the work

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Surface by surface

Window and door perimeters

Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. We follow what’s specified, and colour-matched products can be used where the frame is on show.

Kitchens and utility areas

Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used, food-safe where food contact is possible.

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. If others near Church Whitfield need work, visits can be combined. You will have a fixed quote before work starts.

  1. Drawings, specification and programme come to us.
  2. We take off quantities and return a fixed quote.
  3. We agree with the site team which areas come first.
  4. Plots or floors are sealed as they’re handed over.
  5. Joints are prepared, backed and sealed to the specification.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

What we need from you

  • Send your site hours and access windows
  • Point out any areas we must not close
  • Clear stock, furniture or equipment away from the joints

What sealant work can’t fix

Honesty saves time and money. Fresh joints won’t solve:

  • Glazing units that are cracked or misted
  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
  • Designing joint widths or choosing the specification (that sits with the designer)

If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think.

Surfaces we seal

  • Internal decorators’ caulk
  • Brick and block movement joints
  • Floor and skirting junctions
  • Cladding and panel joints
  • Window and door perimeters
  • Sanitary and kitchen joints

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Sites and facades in and around Church Whitfield

Church Whitfield sits close to the coast, within about 3 miles. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Church Whitfield is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.

Older buildings in the area around Church Whitfield, such as Walmer Castle (4.9 miles north-east of Church Whitfield), need care when sealed: the product has to suit soft or historic materials. School extensions, at buildings such as Whitfield Aspen School, normally run to the summer holidays, mastic included. When a college such as East Kent College (2.6 miles south of Church Whitfield) builds or refurbishes, the mastic package normally has to fit around students and staff.
