Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
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.

Questions we are asked in Foots Cray
Will you work in a care home in Foots Cray without moving residents out?
Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.
Does your area include sites such as Crayfields Business Park, near Foots Cray?
Yes. We cover Foots Cray and the area around it, including industrial estates, business parks and retail parks such as Crayfields Business Park. A few photos and the unit address let us price the work.
Is Foots Cray in your area?
Yes. We cover Foots Cray, and the simplest way to start is to call 01277 525 020 or use the quote form.
How do you reach windows on upper floors?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Our process
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes a day or two for a single block, longer for an estate programme. For a job in Foots Cray, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
What we need from you
- Make sure the joints can be reached
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000

Advice
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Masonry that has broken away beside the joint
- Misted or failed double-glazed units
- Water coming in from the roof or rainwater goods
Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly before you book.

What happens if it’s left?
A bead run over old mastic can look like a repair. It doesn’t bond and normally fails within a short time. Cutting out and resealing properly does it once. Getting scaffold, permits or access booked in Foots Cray takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Do you need mastic sealing in Foots Cray?
The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

Questions to ask before you book
- The named product and why it was chosen
- How they’ll work around occupants
- Whether primer will be used where the manufacturer specifies it
- Their pre-qualification and accreditations
Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Ask residents or tenants to report leaks and draughts early
- Include mastic in your cyclical inspections
- Start inspections with the most exposed faces
- Have the asbestos survey to hand for older buildings
Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.
