Construction mastic in Foots Cray, done properly
Mastic follows everyone else, which means it absorbs every delay upstream. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. If you have inconsistent sealant finishes from plot to plot and missed perimeter joints on a new elevation, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Foots Cray, that means joint design, primers and backing rod as standard.
Around Foots Cray, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Why deal with it now?
Getting the mastic contractor involved early pays off. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification, which avoids last-minute problems. Leave it late and they turn up on the snag list. In Foots Cray, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

FAQs: Foots Cray
Is hospital work, at somewhere like Queen Mary's Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Do you cover business parks and estates near Foots Cray, such as Crayfields Business Park?
Yes. Our area takes in Foots Cray and its surroundings, with estates and business parks such as Crayfields Business Park included. Photos and a short description are enough for a first look.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Can you fit around our working hours?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Do you use the sealant named in the specification?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Ask cleaners to use soft cloths around fresh sealant
- Put any product change through the designer first
- Share drawings and the specification as soon as possible
- Don’t schedule sealing before decorators and flooring are done
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors. Getting the product and preparation right first time avoids that.
Quoting for work in Foots Cray
Each job is priced on its own details. The things that drive the figure:
- Removal of failed or old sealant
- Quantities, in metres or numbers
- Any access equipment needed
- Backing rod, priming and other preparation
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Details that help us quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
- Any specification or named product
- Approximate linear metres or a joint schedule

Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Common problems we fix in Foots Cray
A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.
Look out for the following:
- Inconsistent sealant finishes from plot to plot
- Internal caulk splitting as the building dries out
- Existing joints on a refurb that need cutting out and resealing
- Early adhesion failures on new external joints
Extensions at sites like Queen Mary's Hospital, 0.5 miles west of Foots Cray, usually sit beside working departments, and the mastic follows strict access rules.
Before you book anyone
- Is the sealant right for the movement and the substrate?
- Who will actually carry out the work
- Will RAMS and insurance details be available?
- Their public liability cover
