Construction mastic in West Town, done properly
Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list and clearing them late eats into the handover window. Our aim is joints that pass at the first inspection, area by area through the programme. If you have old sealant on a refurbishment that needs stripping before new work and inconsistent sealant finishes from plot to plot, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in West Town, that means joint design, primers and backing rod as standard.
For a contractor on a smaller site near West Town, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Frame gaps too wide for sealant, which the installer needs to correct
- Faulty frames rather than failed sealant
- Specifying the product where the designer hasn’t
Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
Surfaces we seal
- Sanitary and kitchen joints
- Window and door perimeters
- Brick and block movement joints
- Floor and skirting junctions
- Cladding and panel joints
- Internal decorators’ caulk

Common problems we fix in West Town
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with and gaps beyond it need packing or adjusting by the frame installer. We flag them early rather than filling them with sealant that won’t last.
Site and facilities staff are often the first to spot these:
- Sealant knocked or painted over by other trades
- Frame perimeters left unsealed or poorly sealed
- External joints sealed in damp or cold conditions that are now failing
- Cracks opening in caulked internal joints
For contractors refurbishing units at places like Furniss Business Centre (less than half a mile north-west of West Town), the mastic covers cladding panels, roller-door and window perimeters.
Questions to ask before you book
- How the existing material will be dealt with
- Which product they’ll use, and why it suits the joint
- Whether primer will be used where the manufacturer specifies it
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
After the work
Problems stay small when the joints are checked regularly. Specifically:
- Get the mastic subcontractor involved early in the programme
- Allow flexibility for external sealing in damp or cold weather
- Stick to the specified sealant rather than a generic substitute
- Brief the final clean team to avoid blades near sealant
If a joint is damaged after sealing, flag it early. We can return to clear snags before handover as agreed in the quote.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.
Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself normally taking as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. For a job in West Town, the main thing is a clear picture of the work, so send photographs of each area. A fixed quote follows.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Getting the site ready
- Confirm the product named in the specification
- Tell us what induction or permit system the site runs
- Tell staff and tenants when we’ll be in

How the job changes by surface
External facade and movement joints
Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it, and seal only with a dry joint inside the product’s temperature range.
Snagging before handover
Snags usually come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately, depending on what suits the programme.
Work for main contractors and building owners
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Common questions from West Town clients
Will you plan work around the academic year at somewhere like University of Portsmouth - Langstone Campus?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is West Town off your patch?
Not at all. West Town is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Can you quote from photos?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
How do you work with the site programme?
Working to your programme, we seal each area as it’s handed over. The sequence is agreed with the site manager at the start and updated as the programme moves.
Can you seal external joints in wet or cold weather?
Weather matters for external sealing: the joint needs to be dry and within the product’s temperature range. We plan external elevations with that in mind.
Sites and facades in and around West Town
West Town is within about 1 mile of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. West Town is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.
Hotel extensions and refits, at places such as The Newtown House Hotel (less than half a mile north of West Town), typically run between busy periods, so the sealing is squeezed into short windows. Further education sites such as Portsmouth College, 2.8 miles north-west of West Town, are extended and refurbished from time to time, with mastic often programmed into the summer break.
