Construction mastic in Fairseat

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. New and existing joints then get the same preparation. We work on window and door perimeters, brick and block movement joints and internal decorators’ caulk, and the failures we are asked to look at most are window and door perimeters that won’t pass inspection and different trades sealing to different standards. Most enquiries from Fairseat start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Fairseat, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Advice

Construction mastic in Fairseat: the local picture

Central London is about 22 miles from Fairseat. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.

With historic properties like Old Soar Manor, 4.5 miles to the south of Fairseat, in the area, refurbishment work often meets old masonry that needs compatible sealants. New units and refits on sites such as Invicta Business Park, 1.5 miles to the south of Fairseat, need their panel and perimeter joints sealed to the specification.

Fairseat is about 7 miles north-east of Sevenoaks, in Kent. Commercial clients in Fairseat use us for work on mastic packages. Fairseat is one of 931 places we cover in Kent. There’s a separate page for London, roughly 22 miles from Fairseat.

What the job involves on each surface

Bathrooms, en suites and washrooms

In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly and baths are loaded where appropriate before sealing.

Snagging before handover

The last pass before handover is where mastic snags are cleared. Snags are cleared room by room and damaged joints are redone rather than patched.

Commercial clients in Fairseat

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Approving fire stopping as compliant
  • Designing joint widths or choosing the specification (that sits with the designer)
  • Rework caused by others damaging completed areas

If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Joints and surfaces we work on

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

What sets the cost

The price varies from site to site. It mainly depends on:

  • Quantities, in metres or numbers
  • Whether the work must be split into stages
  • The product specified
  • How much existing material needs removing

Pricing mastic packages depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Details that help us quote

However big the job, these details speed things up:

  • Rough lengths or quantities, or drawings if you have them
  • The site address and postcode
  • Anything awkward about access or site hours
  • Any dates the work must fit around

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email drawings and photos.

Signs you need construction mastic in Fairseat

On construction sites, joints normally fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, and the joint has to be redone.

Things that typically lead to an enquiry:

  • A mastic package split between trades with no clear owner
  • A long mastic snag list close to completion
  • Failed sealant in an existing building being refurbished
  • External joints sealed in damp or cold conditions that are now failing

Projects at schools like Wrotham School work to term dates, so mastic is programmed tightly.

What to look for in a quote

  • Their plan for phasing and protecting the area
  • Are they CHAS accredited or on Constructionline?
  • What site paperwork they can supply
  • Whether old or failed sealant will be cut out, not overlaid

Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Is Fairseat off your patch?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

What guarantee comes with a mastic package?

It’s backed by our 12-month guarantee, covering how we sealed. Keeping other trades off finished joints prevents most problems.
