Crooked Billet: questions and answers
Do you work for managing agents with blocks near Raynes Park station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Share the building’s contractor rules and we will work to them. All of Greater London is inside the ULEZ, and our planning allows for it
What about access for upper-floor joints?
It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How long does a typical visit take?
That varies with the scale of the job, but the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
About our mastic sealing in Crooked Billet
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. We work on shopfronts below residential blocks, communal entrances and stairwells and window and door perimeters on blocks, and the usual reasons a site gets in touch are repeated reactive repairs to the same buildings and damaged joints in communal entrances and corridors. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Crooked Billet is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For managing agents in Crooked Billet, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. All of Greater London is in the ULEZ, and kerbside space in Crooked Billet can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

Do you need mastic sealing in Crooked Billet?
Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Regular cleaning wears them further.
What tends to prompt an enquiry:
- Patchy repairs in mismatched sealant
- Mastic failing across several blocks on an estate
- Movement joints with sealant missing
- No planned programme for sealant
For a school such as Wimbledon College, perimeter mastic on windows and doors is a holiday job.

Quoting for work in Crooked Billet
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- How much existing material needs removing
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
- Joint width, depth and condition
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.
What to include in your enquiry
A few photographs plus some basic facts will normally do. It helps to include:
- Photos of the joints, close up and from further back
- How the joints are reached, and at what height
- The asbestos register, for older buildings
- Whether the building will be occupied during the work
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email drawings and photos.
When to bring in a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Why act early in Crooked Billet
Reacting to every complaint means sending someone out block by block. A planned programme treats each building once and is simpler to manage and budget. Failed sealant in a building in Crooked Billet can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
