How we handle mastic sealing in Kevington
Owners and agents normally inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. We work on shopfronts below residential blocks, communal entrances and stairwells and communal kitchens and washrooms, and the failures we’re asked to look at most are leaks at window and door perimeters and no planned programme for sealant. For commercial sealant work in Kevington, you deal with one contact from quote to sign-off, whether it’s one building or several.
For managing agents in Kevington, resident access, notice periods and the building’s rules shape the job. Work is planned with the agent so residents get notice and access is arranged in advance.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email us and we will arrange a return visit.

Do you need mastic sealing in Kevington?
Occasionally the substrate fails, not the sealant for instance where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
Things that typically lead to an enquiry:
- Open joints in brickwork or panels
- Communal area joints that look neglected
- Estate-wide sealant that is simply worn out
- Complaints coming in block by block
If your remit includes a building such as Manor Oak Primary School, frame and door mastic can be programmed for the holidays.
What your quote should include
- Whether old or failed sealant will be cut out, not overlaid
- The terms of the workmanship guarantee
- Is the sealant right for the movement and the substrate?
- How the joint faces will be prepared and primed
Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Whether the work must be split into stages
- Induction, permit and paperwork requirements
- How much existing material needs removing
- Travel to remote or island sites
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- Specification clauses that apply
- Access details, including height
- The asbestos register, for older buildings
- Where the site is, with the postcode
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or email the details over.

Kevington: questions and answers
Do you take on jobs in Kevington where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. We allow for the ULEZ, which covers every borough
Do you work in occupied care homes around Kevington?
Yes. We work around residents’ routines, a room or two at a time. Noise and disruption are kept to a minimum.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you quote from photographs?
It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
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 we move to the next. In Kevington, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
Before we start on site
- Send your site hours and access windows
- Point out any areas we must not close
- Explain the parking and delivery arrangements

Window and door perimeters on blocks
Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. We’ll confirm the colours available for the specified product.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Honest limits
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Water coming in from the roof or rainwater goods
- Substrate edges that need repairing first
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think.
