New build and refits around West Leith
A number of hotels sit less than 2 miles from West Leith. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. West Leith sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.
Historic houses such as Cholesbury Manor House, 2.3 miles to the south-east of West Leith, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. New units and refits on sites such as Icknield Way Industrial Estate, 0.7 miles to the north of West Leith, need their panel and perimeter joints sealed to the specification.
West Leith is about 5 miles west of Berkhamsted, in Hertfordshire. Commercial clients in West Leith use us for work on facade joints. West Leith is one of 371 places in Hertfordshire on our list. For work in that direction, see our Oxford page (24 miles or so).

Facade sealing for commercial buildings in West Leith
Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear. We work on cladding panel joints, stone and brick facade joints and coping and flashing joints, and what we’re called in for most is perimeter joints where frames meet the structure and weathered facade joints that have lost their grip. A specialist sealant contractor works differently from a general builder: on jobs in West Leith, preparation and product choice get the time they need.
Conversions of older rural buildings near smaller places such as West Leith bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Why it’s worth doing now in West Leith
Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. Around West Leith, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Why appoint us
- One phone line for London, the South East and Scotland
- Health and safety: CHAS accredited

How a job runs
Inspect, seal, sign off: every visit follows that pattern. 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. Jobs in and around smaller places like West Leith are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We start with photographs, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.

Advice
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Cracked or spalling substrates that need repair before sealing
- Arranging specialist high-level access, which is planned with the client
If in doubt, call 01277 525 020 or send details through our quote form and we will say what we think before you book.

Is a smaller place like West Leith outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you hold CHAS accreditation?

How do we ask for a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or send photos by email. Include photographs or drawings if you have them.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Is old mastic on our building likely to contain asbestos?
In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. Removal of asbestos isn’t something we do.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Common problems we fix in West Leith
Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.
Things that normally lead to an enquiry:
- Previous reseals run over old sealant
- Weathered joints at frame-to-structure perimeters
- Draughts around frames and panels
- Discoloured or dirty facade joints
For a contractor at a hotel such as Rose and Crown Hotel, which lies north-east of West Leith, the mastic often has to be finished before a reopening date.

Different surfaces, different methods
Window and door perimeters
Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.
