Construction mastic in East Malling

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Construction mastic in East Malling

Refurbishment work needs a slightly different approach from new build. 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. If you have frame gaps too wide for sealant alone and cracks opening in caulked internal joints, we can help. Most enquiries from East Malling start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Around places like East Malling, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, phone 01277 525 020 or use the quote form and we’ll arrange a return visit.

Site staff or a sealant specialist?

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

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Your questions answered

Will you plan work around the academic year at somewhere like University for the Creative Arts - Maidstone?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is East Malling too far out for you?

Not at all. East Malling is within our area. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

What joints do you seal on a new build?

The scope comes from the specification and drawings, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.

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.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Can you come in just for snagging?

Yes. Share the list and photos, and a fixed quote follows, with the work timed to your handover date.

How much does the work cost?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we’ll price it properly.

Why act early in East Malling

Patching snags as they appear can feel quicker than a proper close-out. But one planned snagging pass through each area normally clears more for less disruption. We can run snagging as its own phase before handover. Small buildings around East Malling suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What you get with us

Signs you need construction mastic in East Malling

Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.

Site and facilities staff are often the first to spot these:

  • Early adhesion failures on new external joints
  • Existing joints on a refurb that need cutting out and resealing
  • Different trades sealing to different standards
  • Bath and shower joints scraped during the final clean

School extensions, at buildings such as St James the Great Academy, typically run to the summer holidays, mastic included.

Questions to ask before you book

  • Their approach to joint depth and backing
  • Health and safety accreditation such as CHAS
  • The named product and why it was chosen
  • How they handle RAMS and site documents

Questions to ask before you appoint anyone

New build and refits around East Malling

The area within 2 miles of East Malling holds several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. East Malling 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.

On a campus such as University for the Creative Arts - Maidstone, 3.2 miles to the south-east of East Malling, new teaching buildings and residences are normally built and refurbished around the academic year. For a contractor at a hotel such as Hamlet Hotel Maidstone (under half a mile north-east of East Malling), the mastic often has to be finished before a reopening date.

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. East Malling can form part of a wider programme.

How a job runs

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Work in places the size of East Malling is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. We walk the site or review drawings to understand the package.
  2. A fixed quote sets out scope, products and phasing.
  3. Paperwork is agreed and applicators are inducted on site.
  4. Sealing follows the programme as areas are released.
  5. Problems we find, such as oversized gaps, are raised right away.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

Preparing the site

Advice

Surface by surface

Internal decorators’ caulk

Caulking is often done in a hurry by whoever’s on site. A neat, consistent caulk line makes the decorators’ job quicker and reduces snags.

Bathrooms, en suites and washrooms

In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line.
