Construction mastic across Eastwood

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

Construction mastic in Eastwood

A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place and gives you a consistent finish across the job. If you are dealing with old sealant on a refurbishment that needs stripping before new work and frame gaps too wide for sealant alone, we can put it right, on window and door perimeters, floor and skirting junctions and internal decorators’ caulk alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Eastwood it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Sites around smaller places like Eastwood can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we will quote to suit.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

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

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Working within restricted access windows
  • Induction, permit and paperwork requirements
  • Quantities, in metres or numbers
  • Distance, for remote addresses

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • How the joints are reached, and at what height
  • Any dates the work must fit around
  • Whether the building will be occupied during the work
  • Approximate linear metres or a joint schedule

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, phone 01277 525 020 or send photos by email.

Surface by surface

Bathrooms, en suites and washrooms

Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Each joint is prepared, sealed and finished with a neat tooled line and baths are loaded where appropriate before sealing.

Internal decorators’ caulk

Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker and keeps the snag list down.

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Protect sealed areas from following trades
  • Share drawings and the specification as soon as possible
  • Allow flexibility for external sealing in damp or cold weather
  • Release areas for mastic once other trades have finished in them

Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead so keep them off the joints.

Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last. We flag them as soon as we see them.

Facades, frames and programmes in Eastwood

Eastwood is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager. Eastwood is about 38 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

With historic properties like Leeds Castle (3.4 miles north-west of Eastwood) in the area, refurbishment work often meets old masonry that needs compatible sealants. School extensions, at buildings such as Ulcombe Church of England Primary School, usually run to the summer holidays, mastic included. Recladding or extending a unit at a site like Roebuck Business Park, 2.6 miles north of Eastwood, brings panel joints and frame perimeters into the programme.

Eastwood is about 7 miles south-east of Maidstone, in Kent. If you’re looking for construction mastic in Eastwood, we can help. Our Kent coverage takes in 931 places. For work in that direction, see our London page (38 miles or so).

Just outside Eastwood, we also work in Broadstone (1 mile south-east), Grafty Green (1 mile east), Ulcombe (1 mile north-west), Fairbourne Heath (1 mile north) and Liverton Street (1 mile north-east).

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

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.

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 your contact hears from us before we move to the next area. If others near Eastwood need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We start with the drawings, specification and programme.
  2. We take off quantities and return a fixed quote.
  3. We agree with the site team which areas come first.

Advice

Questions we are asked in Eastwood

Could you schedule work at a campus like Canterbury Christ Church University for the vacation?

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is Eastwood too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and 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.

When can you be on site?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Is it fine to apply new sealant on top of old?

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

Can you work plot by plot or floor by floor?

The programme sets the job. Tell us the sequence and we’ll plan applicators around it.

What happens if the weather stops external sealing?

Weather matters for external sealing: each sealant has a temperature range, and the joint must be dry. We plan external elevations with that in mind.

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 will plan around them.
