Your questions answered
Would you work within a site like BMI Hendon Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
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.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Can you fit around our programme?
The programme sets the job. Share the release dates and we’ll match our work to them, sealing as areas become ready.
Can you clear a mastic snag list before handover?
Yes. Share the list and photos, and a fixed quote follows.
Construction mastic in The Burroughs, done properly
Perimeter sealing outside needs a dry joint and the right temperature. Each sealant has a temperature range, and damp, frost or condensation on frames stops work, so we plan elevations with the forecast and the programme in mind. Internal areas can usually carry on while the outside waits. If you have new external sealant already peeling away and frame gaps too wide for sealant alone, we can put it right. Facilities teams, main contractors and managing agents in The Burroughs tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in The Burroughs must meet its standards or pay the daily charge. Alongside that, sites usually need booked deliveries and a plan for where materials go.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What else we do in The Burroughs
Commercial clients in The Burroughs
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. The Burroughs can form part of a wider programme across Greater London.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
General trades versus a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
What happens if it’s left?
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal. If the frame is life-expired, we’ll tell you. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
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 rules also count.
Why appoint us
- Joints cleaned back to sound surfaces
- Matching to RAL references, product permitting
- Sealing commercial buildings since 2005
- One contact handling all your sites

What the job involves on each surface
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s for gaps that stay still and get painted.
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. Joints are sealed smooth so they’re easy to clean.
Diagnose, treat, sign off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. All of Greater London is in the ULEZ, and kerbside space in The Burroughs can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Drawings, the sealant specification and your programme come to us for pricing.
- You receive a fixed quote listing scope, products and phasing.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- We close out snagging and hand over with a 12-month guarantee.
What we need from you
- Tell us which areas need to stay in use
- Flag any permit to work we’ll need
- Send any specification or drawings in advance

What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Deciding which fire-stopping product a penetration needs
- Joints damaged after sign-off by following trades
- Faulty frames rather than failed sealant
Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly.
What we seal
- Window and door perimeters
- Internal decorators’ caulk
- Cladding and panel joints
- Brick and block movement joints
- Floor and skirting junctions
- Sanitary and kitchen joints
Building and refurbishing in The Burroughs
Site traffic in The Burroughs falls within London’s ULEZ, like everywhere else in Greater London. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. There are a good number of hotels within about 2 miles of The Burroughs. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
New wings at hospitals like BMI Hendon Hospital, less than half a mile north-east of The Burroughs, bring long runs of window and panel joints to seal. When a college such as College of North West London, 2.6 miles south of The Burroughs, builds or refurbishes, the mastic package typically has to fit around students and staff. For contractors on a campus like Middlesex University, 0.7 miles north-west of The Burroughs, facade and perimeter sealing has to fit around students and term dates.
