About our construction mastic in East Sheen
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place. If you are dealing with old sealant on a refurbishment that needs stripping before new work and perimeter gaps outside the sealant’s range, we can help, whatever the surface. A single leaking joint is often how a building in East Sheen first comes to us: we look at the rest while we are there and tell you what we find.
Every London site, East Sheen included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off.

- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
Before we start on site

Advice
What we can’t put right
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Joints damaged after sign-off by following trades
If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think before you book.

What sets the cost
Each job is priced on its own details. The main factors are:
- The site’s rules and procedures
- The size and state of each joint
- How much there is to seal
- Whether old sealant has to be cut out first
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
What to include in your enquiry
Diagnosis starts before we arrive. Tell us:
- The type of building and who uses it
- Photos of the joints, close up and from further back
- Whether an asbestos survey exists
- Specification clauses that apply

Should maintenance staff do it?
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.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What the job involves on each surface
Window and door perimeters
Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. We follow what’s specified, and colour-matched products can be used where the frame is on show.
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit.
East Sheen: questions and answers
Can work at a site such as University of Roehampton fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you take on work at healthcare sites like Barnes Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you do internal caulk as well as external mastic?
External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging, all priced as one package.
Do you install fire-rated sealant as part of a package?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Tell us what records you need and we’ll confirm with the quote.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
How do you work with the site programme?
We seal plot by plot or floor by floor as areas are released. The sequence is agreed with the site manager at the start and updated as the programme moves.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
