About our construction mastic in Barham

Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list and clearing them late eats into the handover window. We seal so the snag list stays short. Most enquiries involve a mastic package split between trades with no clear owner and snag items on joints that need redoing before handover, on brick and block movement joints, internal decorators’ caulk and cladding and panel joints. Most enquiries from Barham start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

For a site near Barham, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Construction mastic in Barham: the local picture

A 2-mile radius around Barham takes in a number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Central London is about 58 miles from Barham. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.

New wings at hospitals like Kent and Canterbury Hospital (to the north-west of Barham) bring long runs of window and panel joints to seal. With historic properties like Goodnestone Park (to the north-east of Barham) in the area, refurbishment work often meets old masonry that needs compatible sealants.

Barham is about 6 miles south-east of Canterbury, in Kent. We cover commercial sites throughout Barham, for single jobs and planned programmes alike. 931 places across Kent fall within our area, including Barham. There’s a separate page for London, roughly 58 miles from Barham.

Barham: questions and answers

Do you take on work at healthcare sites like Kent and Canterbury Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Barham too small for you to travel to?

Not at all. Barham is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What will the job cost?

Every job gets its own fixed quote. To get one, phone 01277 525 020 or use the quote form.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

How many days will you need on site?

It depends on the scope, but the work usually takes a day or two on a small fit-out and several weeks on a large multi-storey package. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or send details through our quote form. Include photographs or drawings if you have them.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • Joints damaged after sign-off by following trades
  • Deciding which fire-stopping product a penetration needs
  • Faulty frames rather than failed sealant

If in doubt, phone 01277 525 020 or email us and we will say what we think.

Surfaces we seal

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

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Barham can sit alongside others in a wider programme across Kent.

Surface by surface

Fire-rated sealant where specified

Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer and we install what’s specified.

External facade and movement joints

Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.

Signs you need construction mastic in Barham

On construction sites, joints typically 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.

Common reasons buildings call us in:

  • Internal caulk splitting as the building dries out
  • Missed perimeter joints on a new elevation
  • Mastic snags holding up handover
  • Failed sealant in an existing building being refurbished

Hotel extensions and refits, at places such as Broome Park Hotel (1.3 miles south-east of Barham), usually run between busy periods, so the sealing is squeezed into short windows.

What your quote should include

  • Health and safety accreditation such as CHAS
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • The named product and why it was chosen
  • Proof of insurance

Choosing a commercial sealant contractor

What happens if it’s left?

Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area typically clears more for less disruption, and avoids repeated visits. We can run snagging as its own phase before handover. Older rural buildings around Barham move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What you get with us

  • Failed material removed, not covered up
  • One contact handling all your sites
  • CSCS-carded applicators
  • Public liability insurance in place
