Construction mastic in Battersea
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What the job involves on each surface
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted while moving joints need a flexible sealant.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.
Construction mastic in Battersea, done properly
Since 2005 we have worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. To price a package in Battersea, send drawings and the specification through our quote form. The enquiries we see most involve cracks opening in caulked internal joints and sealant knocked or painted over by other trades, across cladding and panel joints, brick and block movement joints and internal decorators’ caulk. Facilities teams, main contractors and managing agents in Battersea tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around Battersea, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Deciding which fire-stopping product a penetration needs
- Specifying the product where the designer hasn’t
- Joints damaged after sign-off by following trades
If in doubt, call 01277 525 020 or email a schedule or drawings and we’ll say what we think.
What we seal
- Brick and block movement joints
- Cladding and panel joints
- Sanitary and kitchen joints
- Floor and skirting junctions
- Internal decorators’ caulk
- Window and door perimeters
Why deal with it now?
Sealing over damaged or contaminated new joints might save a day. New sealant laid on old or dirty sealant has nothing to bond to and the defect reappears in the defects period. We cut out and redo the joint properly. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
What you get with us
- Constructionline member
- CHAS accredited contractor
- Clear, fixed quotes
- Matching to RAL references, product permitting
What sets the cost
To price the job, we consider:
- Backing rod, priming and other preparation
- How accessible the joints are
- Site requirements such as inductions and permits
- How much existing material needs removing
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
Before you send an enquiry
We can often quote from photos and a few details. It helps to include:
- How the joints are reached, and at what height
- The site address and postcode
- Whether the building will be occupied during the work
- Photos of the joints, close up and from further back
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We start with the drawings, specification and programme.
- 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.
Preparing the site
- Point out parking and an unloading spot
- Let building users know which areas are affected
- Make sure the joints can be reached

Advice
Construction mastic in Battersea: the local picture
The ULEZ covers the whole of Greater London, Battersea included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. A 2-mile radius around Battersea takes in a good number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
New units and refits on sites such as Parkfield Industrial Estate, 0.8 miles north-east of Battersea, need their panel and perimeter joints sealed to the specification. For a contractor working at a hospital such as Chelsea and Westminster Hospital, which lies north-west of Battersea, perimeter and facade sealing is planned around patients and deliveries.
Battersea is about 3 miles south-east of Kensington, in Greater London. Across the SW11 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Greater London coverage takes in 764 places, large and small.
We take on mastic packages across the SW11, SW18 and SW4 postcode area. Among the streets we cover are York Road, Este Road and Home Road. Being close to the A3207, Battersea is easy to get to with materials and equipment. We also cover Clapham Junction (1 mile north-west), Sands End (1 mile north-west), Chelsea Harbour (1 mile north-west), Wandsworth (1 mile south-west) and Clapham (1 mile east) for mastic packages. Further afield, our area takes in London (4 miles north-east), City of Westminster (4 miles north), Marylebone (4 miles north), Kensington (3 miles north-west), St Pancras (5 miles north-east) and Shoreditch (6 miles north-east).

What we are called out for in Battersea
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 stick to the specified product, or put any alternative to you first.
Look out for the following:
- Existing joints on a refurb that need cutting out and resealing
- Missed perimeter joints on a new elevation
- Mastic snags holding up handover
- A mastic package split between trades with no clear owner
For contractors at a college like South Thames College Wandsworth Campus (1.1 miles south-west of Battersea), perimeters and internal sealant are timed for the holidays.
