Questions we’re asked in Lambeth
Can you quote for a block close to Vauxhall station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Do you cover business parks and estates near Lambeth, such as Handel Business Centre?
Yes, sites like Handel Business Centre are within our area, along with the rest of Lambeth. A few photos and the unit address let us price the work.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Mastic sealing for commercial buildings in Lambeth
Managing agents and housing associations usually need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. If you have repeated reactive repairs to the same buildings and window mastic that has split and shrunk, we can help, on window and door perimeters on blocks, shopfronts below residential blocks and external wall and movement joints alike. One point of contact handles commercial sealant work in Lambeth from the first photos to the final walk-round, whether it’s one building or several.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Cost factors for mastic joints
To price the job, we consider:
- Backing rod, priming and other preparation
- Phasing around occupants
- Location, for remote and island sites
- The total length or number of joints
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.
What to include in your enquiry
Diagnosis starts before we arrive. Tell us:
- Asbestos survey details if the building is older
- Approximate linear metres or a joint schedule
- The product your specification calls for
- Whether the building will be occupied during the work
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or use the quote form.
What we can’t put right
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Failed window or door frames, which need a window contractor
- Misted or failed double-glazed units
- Substrate edges that need repairing first
If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
What we seal
- Communal kitchens and washrooms
- External wall and movement joints
- Balcony and threshold joints
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- Communal entrances and stairwells
Block-wide mastic in Lambeth
Blocks in London are usually run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We fit the programme to your notice periods. Two care or nursing homes sit less than 2 miles from Lambeth. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.
Blocks of flats and mixed-use buildings often cluster around stations such as Vauxhall station (less than half a mile south-west of Lambeth) and their window and balcony mastic tends to age at the same rate across a building. Student blocks close to universities like London South Bank University, 0.9 miles north-east of Lambeth, are easiest to work on between tenancies. Property owners at sites such as Handel Business Centre, 0.5 miles to the south-west of Lambeth, can have mastic renewed between lettings.
Lambeth is about 1 mile south-west of London, in Greater London. Commercial clients in Lambeth use us for work on mastic joints, as part of our coverage of Greater London. Our Greater London coverage takes in 764 places, large and small.
Anyone looking for mastic sealing in SE11, SW1P and SW8 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. In Lambeth, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Getting the site ready
- Let building users know which areas are affected
- Tell us what induction or permit system the site runs
- Point out parking and an unloading spot

Related advice
Why deal with it now?
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why us?
- Public liability insurance in place
- Constructionline member
- CHAS accredited contractor
- Standard and matched colours in many product ranges
Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- List the paperwork your organisation requires when you send details
- Look at the sunniest and most exposed elevations first
- Plan resealing building by building rather than complaint by complaint
- Log resealing dates block by block
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.
