About our construction mastic in Crooked Billet
Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list, and every return visit costs time. We seal so the snag list stays short. We work on brick and block movement joints, sanitary and kitchen joints and floor and skirting junctions, and what we are called in for most is failed sealant in an existing building being refurbished and missed perimeter joints on a new elevation. One point of contact handles commercial sealant work in Crooked Billet from the first photographs to the final walk-round, for single jobs and planned programmes alike.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Facades, frames and programmes in Crooked Billet
Crooked Billet has a good number of hotels close by, all within 2 miles. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. As part of Greater London, Crooked Billet is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
New units and refits on sites such as Rainbow Industrial Estate, 1 mile to the south of Crooked Billet, need their panel and perimeter joints sealed to the specification. For contractors on a campus like Kingston University Roehampton Vale Campus, 1.5 miles to the north-west of Crooked Billet, facade and perimeter sealing has to fit around students and term dates. Further education sites such as Wimbledon College of Arts, 0.9 miles south-east of Crooked Billet, are extended and refurbished from time to time, with mastic often programmed into the summer break.
Crooked Billet is about 1 mile west of Wimbledon, in Greater London. Crooked Billet sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else.

What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Frame gaps too wide for sealant, which the installer needs to correct
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Glazing units that are cracked or misted
If in doubt, ring 01277 525 020 or email a schedule or drawings and we will say what we think.
Surfaces we seal
- Sanitary and kitchen joints
- Brick and block movement joints
- Internal decorators’ caulk
- Floor and skirting junctions
- Window and door perimeters
- Cladding and panel joints

For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Our process
In a busy building, the work is phased so only one area is out of use at a time. 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 Crooked Billet 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, the sealant specification and your programme come to us for pricing.
- You receive a fixed quote listing scope, products and phasing.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- We seal each plot or floor as it’s released to us.
- Every joint is prepared, set to depth and sealed with the specified product.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Preparing the site
- Confirm the product named in the specification
- Tell staff and tenants when we’ll be in
- Send asbestos survey details if the building is pre-2000

Related advice
Why deal with it now?
It helps to bring the mastic subcontractor in before the package is urgent. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification. Leave it late and they turn up on the snag list. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
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 you get with us
- One phone line for London, the South East and Scotland

Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Ask for joint and product checks before the package is urgent
- Protect sealed areas from following trades
- Plan external elevations with the weather in mind
- Keep product details for future maintenance
After we have sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out.
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
