Mastic sealing for commercial buildings in West Brompton
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. Site teams most often ask us about leaks at window and door perimeters and communal area joints that look neglected, across communal kitchens and washrooms, balcony and threshold joints and communal entrances and stairwells. Whoever orders the work in West Brompton, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. We work to the agent’s notice and access plan, so residents know what’s happening.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or send photos by email and we will arrange a return visit.

On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints, and we clear our waste as we work. Planning a London job such as one in West Brompton starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.
Getting the site ready
- Let building users know which areas are affected
- Tell us which areas need to stay in use
- Make sure the joints can be reached

FAQs: West Brompton
Does your area include sites such as Brompton Cross District Shopping Centre., near West Brompton?
Yes, sites like Brompton Cross District Shopping Centre. Are within our area, along with the rest of West Brompton. To start, just ring 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Do you cover West Brompton?
Yes. West Brompton falls within our area, and the simplest way to start is to phone 01277 525 020 or email us.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
What we are called out for in West Brompton
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Typical triggers for a call:
- No planned programme for sealant
- Draughts at frames across a block
- Damaged joints in communal entrances and corridors
- Cracked, hardened mastic round windows on a block
Churches, halls and community buildings such as Church of St Luke are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Questions to ask before you book
- Their public liability cover
- How joint depth will be controlled
- Is the sealant right for the movement and the substrate?
- Are they CHAS accredited or on Constructionline?
General trades versus a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What the job involves on each surface
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. We quote building by building and work through them in turn.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Water coming in from the roof or rainwater goods
- Broken glass or failed sealed units
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
Not sure which it is? You can ring 01277 525 020 or email the details over and we will tell you honestly.
