Mastic sealing across Westbourne Green
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Cost factors for mastic joints
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Removal of failed or old sealant
- The site’s rules and procedures
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
Before you send an enquiry
We can often quote from photos and a few details. Please tell us:
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
- Access details, including height
- The product your specification calls for
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
About our mastic sealing in Westbourne Green
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on communal kitchens and washrooms, balcony and threshold joints and window and door perimeters on blocks, and the usual reasons a site gets in touch are mastic failing across several blocks on an estate and damp patches beside frames. Searching for sealant specialists in Westbourne Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building, which is why block-wide programmes make sense.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

On site: what to expect
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready

Advice
FAQs: Westbourne Green
Do you work for managing agents with blocks near London Paddington station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Will you take on work at estates like Stable Way Industrial Estate, close to Westbourne Green?
Yes. Estates, retail parks and business parks around Westbourne Green, Stable Way Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.
How many days will you need on site?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Glazing that needs replacing
- Water coming in from the roof or rainwater goods
- Failed window or door frames, which need a window contractor
If you’re not sure, just ring 01277 525 020 or email us and we’ll give you a straight answer.
Joints and surfaces we work on
- External wall and movement joints
- Balcony and threshold joints
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- Window and door perimeters on blocks
Why deal with it now?
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why us?
- Matching to RAL references, product permitting
- Work to your specification and the manufacturer’s guidance
- Failed material removed, not covered up
- Colours confirmed for the specified product

Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Encourage occupiers to report problems at frames
- Share your contractor requirements early
- Have the asbestos survey to hand for older buildings
- Plan resealing building by building rather than complaint by complaint
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
