About our mastic sealing in West Drayton
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Resealed mastic joints in West Drayton carry our 12-month guarantee. Most enquiries involve occupiers reporting cold air round windows and patchy repairs in mismatched sealant, on window and door perimeters on blocks, balcony and threshold joints and shopfronts below residential blocks. A single leaking joint is often how a building in West Drayton first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
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.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Quoting for work in West Drayton
Your fixed quote is built from the real scope. It takes account of:
- Which sealant the job calls for
- Access and working height
- Location, for remote and island sites
- Whether the work must be split into stages
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Diagnosis starts before we arrive. Tell us:

West Drayton: questions and answers
Does your area include sites such as Northpoint Business Centre, near West Drayton?
Yes. Estates, retail parks and business parks around West Drayton, Northpoint Business Centre among them, are all within reach. Photos and a short description are enough for a first look.
We manage a building near West Drayton station. Can you help?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
How do you handle work on occupied blocks?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so it can be arranged.
Do you work with property factors and landlords?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Different surfaces, different methods
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. Quotes can be per block or for the full programme.
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and spreads the work.
Blocks and managed buildings in West Drayton
London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. Our programme follows the access you agree with residents.
Older community buildings, Church of St Martin among them, often have frames of mixed ages whose mastic varies. Student blocks close to universities like Brunel University of London (2 miles north of West Drayton) are easiest to work on between tenancies.

What we’re called out for in West Drayton
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
Look out for the following:
- Cracked, hardened mastic round windows on a block
- Water getting in round frames after rain
- No planned programme for sealant
- Worn sealant at communal door frames
If you look after a block within reach of West Drayton station, 0.5 miles to the north-west of West Drayton, frame and balcony mastic can be renewed on one programme.
Before you book anyone
- Their pre-qualification and accreditations
- What level of public liability insurance do they hold?
- How the joint faces will be prepared and primed
- Will RAMS and insurance details be available?
Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. In West Drayton, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- 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.
- Buildings are completed in turn.
Getting the site ready

Advice
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Share your contractor requirements early
- Ask residents or tenants to report leaks and draughts early
- Have the asbestos survey to hand for older buildings
- Make mastic part of routine maintenance checks
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.
