Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Planning a London job such as one in Kevington starts with access. Send the building rules and access times with your enquiry.
- We price from the drawings, specification and programme you send.
- We return a fixed quote that ties the mastic package to your programme.
- 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.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- We close out snagging and hand over with a 12-month guarantee.
Before we start on site
- Flag any permit to work we’ll need
- Agree which areas must stay open
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Construction mastic in Kevington
The specification and the programme set the job, not to habit. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. We work on brick and block movement joints, window and door perimeters and cladding and panel joints, and the failures we are asked to look at most are old sealant on a refurbishment that needs stripping before new work and frame perimeters left unsealed or poorly sealed. One point of contact handles commercial sealant work in Kevington from the first photographs to the final walk-round, whether it’s one building or several.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

General trades versus a specialist
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.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Quoting for work in Kevington
The price varies from site to site. It mainly depends on:
- Working within restricted access windows
- Removal of failed or old sealant
- Specialist products, such as fire-rated or hygienic sealants
- Induction, permit and paperwork requirements
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What we need to price the job
A few photos plus some basic facts will normally do. It helps to include:
- Asbestos survey details if the building is older
- The postcode of the building
- Photos of the joints, close up and from further back
- Anything awkward about access or site hours
Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, phone 01277 525 020 or email drawings and photos.
What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Frame gaps too wide for sealant, which the installer needs to correct
- Deciding which fire-stopping product a penetration needs
- Defective windows, doors or glazing units (the supplier or installer’s job)
If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.
Joints and surfaces we work on
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Cladding and panel joints
- Window and door perimeters
- Floor and skirting junctions
- Brick and block movement joints

Contractors’ notes for Kevington
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Kevington. Delivery slots and scarce storage shape how and when the mastic goes in. There are a number of hotels within about 2 miles of Kevington. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
Recladding or extending a unit at a site like Nugent Retail Park, 1.1 miles to the north-west of Kevington, brings panel joints and frame perimeters into the programme. New wings at hospitals like Chelsfield Park Hospital (to the south of Kevington) bring long runs of window and panel joints to seal.
Kevington is about 1 mile east of Orpington, in Greater London. If you are looking for construction mastic in Kevington, we can help, as we do across Greater London. Across Greater London, 764 places are covered, Kevington among them. Sites around London have their own page, roughly 13 miles from Kevington.

Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Plan external elevations with the weather in mind
- Ask cleaners to use soft cloths around fresh sealant
- Keep product details for future maintenance
- Put any product change through the designer first
Record which products went where in the handover file. Future maintenance is easier when the products are known and avoids guesswork when joints are renewed. We can confirm the handover information you need when we quote.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure, so the installer needs to correct it first. We raise them during our first walk of the area.
Common problems we fix in Kevington
Value-engineered products sometimes end up in the wrong joints. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
Clients usually get in touch after noticing something like this:
- Frame perimeters left unsealed or poorly sealed
- Snag items on joints that need redoing before handover
- Caulk cracking where joints are moving more than expected
- Inconsistent sealant finishes from plot to plot
For a contractor at a hotel such as TLK Apartments & Hotel, which lies north-west of Kevington, the mastic often has to be finished before a reopening date.
