Mastic sealing for commercial buildings in White City

We are CHAS accredited and a Constructionline member, with public liability insurance. If you have complaints coming in block by block and mastic failing across several blocks on an estate, we can put it right. Facilities teams, main contractors and managing agents in White City tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In a London area such as White City, 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.

FAQs: White City
Will you take on work at estates like Stable Way Industrial Estate, close to White City?
Yes. Our area takes in White City and its surroundings, with estates and business parks such as Stable Way Industrial Estate included. Photos and a short description are enough for a first look.
We manage a building near Shepherds Bush station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
Will residents or tenants be disturbed?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- For older buildings, check the asbestos register before work
- Tell us what induction or permit system the site runs
- Warn occupants and staff about the work

Blocks and managed buildings in White City
Blocks in London are typically run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We work to your notice and access plan.
For a school such as Ark Swift Primary Academy, perimeter mastic on windows and doors is a holiday job. If you look after a block within reach of Shepherds Bush station (0.5 miles south-east of White City), frame and balcony mastic can be renewed on one programme.
White City is about 1 mile north-west of Kensington, in Greater London. We send applicators to White City for mastic joints. Across Greater London, 764 places are covered, White City among them. Sites around London have their own page, about 6 miles away.
Commercial sites across W12, W11 and W10 are covered for mastic joints. We cover commercial and managed buildings on Bard Road, Wood Lane and Abdale Road and the roads nearby.

Should maintenance staff do it?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Why it’s worth doing now in White City
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Quoting for work in White City
Your fixed quote is built from the real scope. It takes account of:
- Phasing around occupants
- Whether old sealant has to be cut out first
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- Your programme or deadline
- Specification clauses that apply
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Signs you need mastic sealing in White City
Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Cleaning products add to the wear.
Site and facilities staff are often the first to spot these:
- Draught complaints from residents or tenants
- Damaged joints in communal entrances and corridors
- Window mastic that has split and shrunk
- Open joints in brickwork or panels
If you own or manage units on a site such as Stable Way Industrial Estate, less than half a mile north-east of White City, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Maintenance after handover
Regular inspection catches problems early. In particular:
- Mention RAMS, insurance or CSCS requirements up front
- Plan resealing building by building rather than complaint by complaint
- Make it easy for occupiers to report draughts
- Make mastic part of routine maintenance checks
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
