How we handle construction mastic in Bush Hill
Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Bush Hill, send drawings and the specification through our quote form. If you have frame gaps too wide for sealant alone and early adhesion failures on new external joints, we can put it right, on cladding and panel joints, window and door perimeters and internal decorators’ caulk alike. Whoever orders the work in Bush Hill, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. Mastic is typically one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Cost factors for mastic packages
There’s no standard rate for sealant work, because every site is different. What we look at:
- How much there is to seal
- Working within restricted access windows
- Induction, permit and paperwork requirements
- Location, for remote and island sites
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
Sending details for a quote
Whether it’s one area or a whole building, these details speed things up:
- A wide shot and a close-up of the area
- Whether the building will be occupied during the work
- Approximate linear metres or a joint schedule
- Access details, including height
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Check frame gaps are within the sealant’s range before sealing
- Plan external elevations with the weather in mind
- Keep product details for future maintenance
- Bring the mastic contractor in after the last trades are through
The package carries our 12-month guarantee for workmanship. The guarantee covers how we sealed, not later damage by other trades, so protecting sealed areas matters.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.
Site staff or a sealant specialist?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Your questions answered
Do you take on jobs in Bush Hill where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we’ll work to them.
Would you work within a site like The Cavell Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Do you use the sealant named in the specification?
We follow the specified sealant. Product standards such as BS EN 15651 are often named in specifications.
Can the building stay open while you work?
In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Is the mastic package guaranteed?
Our workmanship carries a 12-month guarantee from sign-off. Damage by others after we’ve finished isn’t covered.
How a job runs
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it.

- 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.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
What we need from you
- Point out parking and an unloading spot
- Have the specification and drawings to hand
- Share your working hours and any access restrictions

Advice
Surface by surface
External facade and movement joints
External movement joints often need primer, depending on the substrate. We prime where the manufacturer specifies, and seal only with a dry joint inside the product’s temperature range.
Window and door perimeters
Internal perimeters are normally sealed with a paintable product where decorating follows. We follow what’s specified.
Construction mastic around Bush Hill: how the place shapes the job
Site traffic in Bush Hill falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. There are a number of hotels within about 2 miles of Bush Hill. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
New units and refits on sites such as Great Cambridge Industrial Estate (to the east of Bush Hill) need their panel and perimeter joints sealed to the specification. Projects at colleges like Capital City College (1.9 miles north-east of Bush Hill) tend to run to term dates, so the mastic is planned tightly.

Do you need construction mastic in Bush Hill?
Frames installed with uneven gaps make perimeter sealing harder. Sealant has a range of joint widths it can cope with. Better to raise it at the start than seal a joint that’s bound to fail.
If one of these sounds familiar, it’s time for a closer look:
- Mastic snags holding up handover
- Internal caulk splitting as the building dries out
- Inconsistent sealant finishes from plot to plot
- Early adhesion failures on new external joints
University estates such as University of Portsmouth Walthamstow Campus (to the south-east of Bush Hill) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
