Construction mastic in Locksbottom, done properly
Getting a subcontractor through site induction should be simple. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. If you’re dealing with cracks opening in caulked internal joints and window and door perimeters that won’t pass inspection, we can help, on floor and skirting junctions, internal decorators’ caulk and cladding and panel joints alike. Most enquiries from Locksbottom start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Locksbottom must meet its standards or pay the daily charge. Alongside that, sites typically need booked deliveries and a plan for where materials go.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Facades, frames and programmes in Locksbottom
A 2-mile radius around Locksbottom takes in several hotels. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. As part of Greater London, Locksbottom is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed.
School extensions, at buildings such as Darrick Wood Infant & Nursery School, normally run to the summer holidays, mastic included. Projects at colleges like Bromley College (1.5 miles north-west of Locksbottom) tend to run to term dates, so the mastic is planned tightly.

On site: what to expect
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. All of Greater London is in the ULEZ, and kerbside space in Locksbottom can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
Before we start on site
- Confirm the product named in the specification
- Share the asbestos register for older buildings
- Flag any permit to work we’ll need

After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep product details for future maintenance
- Brief the final clean team to avoid blades near sealant
- Share drawings and the specification as soon as possible
- Check frame gaps are within the sealant’s range before sealing
If a joint is damaged after sealing, flag it early. We can return to clear snags before handover as agreed in the quote.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out.
Quoting for work in Locksbottom
Before we quote, we look at:
- Any access equipment needed
- Quantities, in metres or numbers
- Joint width, depth and condition
- Induction, permit and paperwork requirements
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
- Specification clauses that apply
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
For managing agents and facilities managers
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
FAQs: Locksbottom
Will you plan work around the academic year at somewhere like Bromley College?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you work at a site such as Glebe Farm Business Park, by Locksbottom?
Yes. Estates, retail parks and business parks around Locksbottom, Glebe Farm Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
What accreditations do you hold?
We’re CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are also fully insured, with five million pounds of public liability cover.
Is colour matching possible?
It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Can you quote from photos?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
How long does a job like this take?
It depends on the scope, but the work usually takes a day or two on a small fit-out and several weeks on a large multi-storey package. For bigger or phased jobs, we’ll set out a timescale with the quote.
When to call us in Locksbottom
A new building moves while it dries and settles. Materials lose construction moisture and shrink and internal caulk in a moving joint is usually the first to crack. Picking a flexible sealant where there’s movement keeps snags down.
If one of these sounds familiar, it’s time for a closer look:
- Internal caulk splitting as the building dries out
- External joints sealed in damp or cold conditions that are now failing
- Frame gaps too wide for sealant alone
- Different trades sealing to different standards
For contractors refurbishing units at places like Glebe Farm Business Park (2 miles south-west of Locksbottom), the mastic covers cladding panels, roller-door and window perimeters.
What your quote should include
- Their approach to joint depth and backing
- Their plan for phasing and protecting the area
- Do they follow the manufacturer’s priming guidance?
- What site paperwork they can supply
Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Approving fire stopping as compliant
- Damage to finishes by other trades after we’ve sealed
- Frame gaps too wide for sealant, which the installer needs to correct
If you’re not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer before you book.
