Signs you need construction mastic in Great Canney
On construction sites, joints normally 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.
Any of the following is a good reason to get the joints checked over:
- Inconsistent sealant finishes from plot to plot
- Cracks opening in caulked internal joints
- A long mastic snag list close to completion
- Bath and shower joints scraped during the final clean
School extensions, at buildings such as Cold Norton Primary School, normally run to the summer holidays, mastic included.

Construction mastic in Great Canney, done properly
On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. The enquiries we see most involve external joints sealed in damp or cold conditions that are now failing and existing joints on a refurb that need cutting out and resealing, on internal decorators’ caulk, window and door perimeters and cladding and panel joints.

What else we do in Great Canney
New build and refits around Great Canney
Central London is about 34 miles from Great Canney. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. Rainfall across the South East, Great Canney included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.
Recladding or extending a unit at a site like Great Hayes Business Centre, 1.3 miles south of Great Canney, brings panel joints and frame perimeters into the programme.

Surface by surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps. Tell us what records you need and we’ll confirm with the quote.
Internal decorators’ caulk
Caulk is easy to apply badly. Done properly, it saves decorators time and gives a clean line and reduces snags.
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Your questions answered
Is Great Canney too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Do you cover business parks and estates near Great Canney, such as Great Hayes Business Centre?
Yes. Estates, retail parks and business parks around Great Canney, Great Hayes Business Centre among them, are all within reach. A few photos and the unit address let us price the work.
Can you fit around our programme?
Our work is sequenced around the programme. Each plot, floor or elevation is sealed when it’s ready and we tell you if something stops an area being sealed.
Do you do fire-rated sealing on new builds?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. The design and sign-off belong to the designer, fire engineer or building control.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can staff carry on working while you’re here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Share drawings and the specification as soon as possible
- Don’t force external sealing on a damp or frosty day
- Bring the mastic contractor in after the last trades are through
- Flag uneven or tapered frame gaps early
After we’ve sealed an area, it helps to keep other trades from damaging the joints. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked; we confirm the time for each product.
A missed perimeter seal on one window can wet the reveal and the plaster inside. That typically means redoing finishes in a completed area and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.
On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near Great Canney need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
