New build and refits around Mill Hill
Mill Hill is within about 2 miles of the coast. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. A 2-mile radius around Mill Hill takes in plenty of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
When a school such as St Mary's Catholic Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Hotels like Queens Hotel (1.3 miles north-east of Mill Hill) rarely close for long, so refurbishment mastic is phased floor by floor.
Mill Hill is about 1 mile west of Deal, in Kent. Mill Hill sits inside our coverage and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. Mill Hill is one of 931 places we cover in Kent. Our London page has more on work in that area, about 67 miles away.

How we handle construction mastic in Mill Hill
On a new build, the mastic package is one of the last trades through each area, so it lands at exactly the point the programme is tightest. We work as a mastic subcontractor to main contractors and developers on schemes in Mill Hill. We work on brick and block movement joints, internal decorators’ caulk and sanitary and kitchen joints, and what we’re called in for most is missed perimeter joints on a new elevation and perimeter gaps outside the sealant’s range. A single leaking joint is often how a building in Mill Hill first comes to us: we look at the rest while we are there and tell you what we find.
On a small site around Mill Hill, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we’ll time the work so nothing waits on us.
Work we carry out in Kent comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email us and we will come back to it.

Leave it or put it right?
A cheaper sealant can look like an easy saving on a large package. A failed joint in the defects period costs far more than the product difference, especially externally. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
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 rules also count.

How the quote is worked out
To price the job, we consider:
- Whether old sealant has to be cut out first
- How much there is to seal
- Working within restricted access windows
- Travel to remote or island sites
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What we need to price the job
There’s no need for a formal survey. A few details are enough to get going:
- Specification clauses that apply
- Whether the building will be occupied during the work
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
On site: what to expect
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a job in Mill Hill, the main thing is a clear picture of the work. You will then get a fixed price for the work.

- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.

Common questions from Mill Hill clients
Would you work within a site like Victoria Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Is Mill Hill too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
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.
How do you work with the site programme?
The programme sets the job. Tell us the sequence and we’ll plan applicators around it, sealing as areas become ready.
Do you need construction mastic in Mill Hill?
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.
Any of the following is a good reason to get the joints checked over:
- Missed perimeter joints on a new elevation
- Old sealant on a refurbishment that needs stripping before new work
- Early adhesion failures on new external joints
- Sanitary sealant damaged by following trades
For a contractor working at a hospital such as Victoria Hospital, which lies north-east of Mill Hill, perimeter and facade sealing is planned around patients and deliveries.
What to look for in a quote
- Do they follow the manufacturer’s priming guidance?
- What site paperwork they can supply
- Which product they’ll use, and why it suits the joint
- How they’ll work around occupants
What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Designing joint widths or choosing the specification (that sits with the designer)
- Frames fitted out of tolerance
- Joints damaged after sign-off by following trades
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
