Construction mastic in York Town

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Release areas for mastic once other trades have finished in them
  • Get the mastic subcontractor involved early in the programme
  • Use the product the specification names
  • Protect sealed areas from following trades

Any damage after we have finished should go on the snag list right away. We can return to clear snags before handover.

Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure so packing or adjustment by the installer comes first. We raise them during our first walk of the area.

How we handle construction mastic in York Town

Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone, 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 sanitary and kitchen joints, internal decorators’ caulk and cladding and panel joints, and the usual reasons a site gets in touch are sealant knocked or painted over by other trades and old sealant on a refurbishment that needs stripping before new work. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in York Town it comes down to the same thing: the right product in a properly prepared joint.

On a small site around York Town, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Common questions from York Town clients

Can you take on a job at a hospital such as Frimley Park Hospital?

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.

Will you plan work around the academic year at somewhere like The Sixth Form College Farnborough?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

What accreditations do you hold?

CHAS and Constructionline are both in place, and each applicator is CSCS-carded. We are fully insured for public liability.

Do you work in York Town?

Yes. Sites across York Town are covered, with one number for every area we cover.

How many days will you need on site?

That varies with the scale of the job, but the work normally takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Is the mastic package guaranteed?

It carries a 12-month guarantee on our workmanship. We are also fully insured for public liability.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around York Town. Several sites can go on one quote, which keeps the paperwork simple.

How the job changes by surface

Fire-rated sealant where specified

Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services, and we’ll tell you if the detail calls for something else. Tell us what records you need and we’ll confirm with the quote.

Bathrooms, en suites and washrooms

Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent.

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Several jobs near York Town can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. We walk the site or review drawings to understand the package.
  2. You receive a fixed quote covering scope, products and sequence.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  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.

What we need from you

  • Send asbestos survey details if the building is pre-2000

Joints and surfaces we work on

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

Construction mastic around York Town: what changes locally

York Town is about 31 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. York Town sits in one of the drier corners of the country, the South East. 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.

For contractors at a school such as South Camberley Primary and Nursery School, sealing has to be finished before term starts. Further education sites such as The Sixth Form College Farnborough (2 miles south of York Town) are extended and refurbished from time to time, with mastic often programmed into the summer break. New units and refits on sites such as Basepoint Business Centre (to the north-west of York Town) need their panel and perimeter joints sealed to the specification.

York Town is about 1 mile west of Camberley, in Surrey. Our applicators travel to York Town for work on mastic packages, handled exactly as we handle every other area. York Town is one of 379 places in Surrey on our list for mastic packages. Reading is covered too, some 12 miles away.

Should maintenance staff do it?

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

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.
