Questions about Larkfield
Is hospital work, at somewhere like Maidstone Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Is Larkfield too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Can you find out why a window is leaking?
Yes. We look at the perimeter sealant and tell you whether it has failed before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
Do you run new sealant over the existing bead?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. Nothing else gives a bond that lasts.
What type of sealant goes on window perimeters?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Facade sealing in Larkfield
Managing agents and owners in Larkfield ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. We work on stone and brick facade joints, cladding panel joints and perimeter joints where frames meet the structure, and the failures we are asked to look at most are damp patches beside frames after rain and air leaks through failed facade joints. Searching for sealant specialists in Larkfield? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
In the countryside around places like Larkfield, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself usually taking a day or two for a few elevations, and longer where access has to be moved around the building. For work around Larkfield, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We start with photographs, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
What we need from you
- For older buildings, check the asbestos register before work

What the job involves on each surface
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.
Brick and stone facades
Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.
Common problems we fix in Larkfield
When the sealant tears down its centre, it has usually been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
Any of the following is a good reason to get the joints checked over:
- Old perimeter mastic that has dried out
- Unsightly perimeter sealant on a visible elevation
- Gaps between rainscreen or cladding panels
- Perimeter joints where frames meet the structure
University estates such as University for the Creative Arts - Maidstone, 3.3 miles south-east of Larkfield, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

There’s no need for a formal survey. A few details are enough to get going:
- Whether the building will be occupied during the work
- Specification clauses that apply
- When you need the work done

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or email a schedule or drawings.
Mastic packages on Larkfield sites
Larkfield sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. Larkfield is about 27 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
For a contractor working at a hospital such as Maidstone Hospital, 2.7 miles to the south-east of Larkfield, perimeter and facade sealing is planned around patients and deliveries. School extensions, at buildings such as Brookfield Junior School, normally run to the summer holidays, mastic included.

Honest limits

- Installing or repairing glazing systems
- Water getting in through cracked render or porous masonry
- Render or concrete edges that have broken away

Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Keep pressure washers away from fresh sealant
- Inspect facade joints on a regular cycle
- Avoid patch repairs on failed facade joints
- Keep the sealant details on the building file
Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly using a matching sealant.
Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.
