What we can’t put right
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Masonry that has broken away beside the joint
- Asbestos-containing sealant, which we don’t remove
- Failed window or door frames, which need a window contractor
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
Surfaces we seal
- External wall and movement joints
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- Balcony and threshold joints
Mastic sealing for commercial buildings in Holland Park
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you’re dealing with repeated reactive repairs to the same buildings and open joints in brickwork or panels, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Holland Park it comes down to the same thing: the right product in a properly prepared joint.
In a London area such as Holland Park, many buildings are blocks of flats or mixed-use buildings run by managing agents, landlords or housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Holland Park: questions and answers
Will you take on work at estates like Berghem Mews Business Village, close to Holland Park?
Yes, sites like Berghem Mews Business Village are within our area, along with the rest of Holland Park. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can you quote for a block close to Kensington Olympia station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Can you send RAMS and CSCS details before starting?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Will residents or tenants be disturbed?
The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
After the work
Keep the joints in good shape with a few simple steps:
- Check the asbestos register before any old mastic is disturbed
- Prioritise elevations facing the weather
- Ask residents or tenants to report leaks and draughts early
- Reduce knocks to communal area joints
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing.
What happens if it’s left?
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work with less control over timing. Failed sealant in a building in Holland Park 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.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
What you get with us
- Coloured sealants to suit the setting, where available
- Clear, fixed quotes
- Joints cleaned back to sound surfaces
- Fully insured, including public liability cover
