How we handle construction mastic in Boughton Monchelsea

Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal areas can normally carry on while the outside waits. We work on brick and block movement joints, cladding and panel joints and floor and skirting junctions, and the failures we’re asked to look at most are sanitary sealant damaged by following trades and caulk cracking where joints are moving more than expected. A specialist sealant contractor works differently from a general builder: in Boughton Monchelsea, that means joint design, primers and backing rod as standard.

In the countryside around places like Boughton Monchelsea, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area.

  1. We walk the site or review drawings to understand the package.
  2. A fixed quote sets out scope, products and phasing.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. Sealing follows the programme as areas are released.
  5. Any frame gaps or issues outside our scope are flagged to the site team.
  6. Final snagging is completed and the 12-month guarantee applies.

Questions about Boughton Monchelsea

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

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is a hospital such as Oakwood Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

What hours do you work?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

What joints do you seal on a new build?

Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens, all priced as one package.

Can you clear a mastic snag list before handover?

Yes, we can. Send the snag list or photographs and we will price it.

Common problems we fix in Boughton Monchelsea

On construction sites, joints usually fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated.

These are often picked up first by site or facilities staff:

  • Old sealant on a refurbishment that needs stripping before new work
  • Cracks opening in caulked internal joints
  • Different trades sealing to different standards
  • Sanitary sealant damaged by following trades

For a contractor working at a hospital such as Oakwood Hospital, 3.3 miles north-west of Boughton Monchelsea, perimeter and facade sealing is planned around patients and deliveries.

Questions to ask before you book

  • Will failed sealant be removed rather than covered?
  • How they handle RAMS and site documents
  • How they’ll work around occupants
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

Aftercare for building managers

Cleaning and maintenance staff play a part too. Share these points with them:

  • Keep finished joints away from paint, plaster and scrapers
  • Ask installers to correct oversized gaps first
  • Ask for joint and product checks before the package is urgent
  • Ask cleaners to use soft cloths around fresh sealant

Our 12-month guarantee covers the workmanship from sign-off. The guarantee covers how we sealed, not later damage by other trades, so protecting sealed areas matters.

Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure. We flag them as soon as we see them.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

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

How the job changes by surface

Internal decorators’ caulk

Caulk is easy to apply badly. Done properly, it saves decorators time and gives a clean line and keeps the snag list down.

Bathrooms, en suites and washrooms

Across a block of flats or a hotel, sanitary sealing is repeated in every room. One applicator team gives the same finish everywhere following the programme.

For managing agents and facilities managers

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
