Construction mastic in Five Ash Down, done properly
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. Splitting those between trades often leaves gaps in responsibility and gives you a consistent finish across the job. We work on internal decorators’ caulk, floor and skirting junctions and brick and block movement joints, and the usual reasons a site gets in touch are oversized or tapered gaps around new frames and sanitary sealant damaged by following trades. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Five Ash Down, that means joint design, primers and backing rod as standard.
In the countryside around places like Five Ash Down, 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.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Five Ash Down are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- 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.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Before we start on site
- Share your working hours and any access restrictions
- Point out any areas we must not close
- For older buildings, check the asbestos register before work

Advice
Different surfaces, different methods
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control and we install what’s specified.
Snagging before handover
Snags typically come from damage by following trades, missed joints or poor earlier work. We price snagging as part of the package or as a separate visit, depending on what suits the programme.
Building owners, agents and FMs in Five Ash Down
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Five Ash Down can sit alongside others in a wider programme across East Sussex.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Common problems we fix in Five Ash Down
Wide, tapered or inconsistent gaps around frames are a common problem. Every product has limits on how wide a joint it can bridge. We flag them early rather than filling them with sealant that won’t last.
Site and facilities staff are often the first to spot these:
- Sealant knocked or painted over by other trades
- Mastic snags holding up handover
- New external sealant already peeling away
- Failed sealant in an existing building being refurbished
Projects at schools like Buxted CofE Primary School work to term dates, so mastic is programmed tightly.
What to look for in a quote
- Are they CHAS accredited or on Constructionline?
- Whether old or failed sealant will be cut out, not overlaid
- What the guarantee covers, and for how long
- Will CSCS-carded applicators be on site?
Why deal with it now?
Sealing over damaged or contaminated new joints might save a day, but it won’t last. New sealant laid on old or dirty sealant has nothing to bond to. We cut out and redo the joint properly. Older rural buildings around Five Ash Down move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Deciding which fire-stopping product a penetration needs
- Frame gaps too wide for sealant, which the installer needs to correct
- Joints damaged after sign-off by following trades
If in doubt, phone 01277 525 020 or email drawings and photos and we will say what we think before you book.

Questions about Five Ash Down
Does your area include sites such as Ashdown Business Park, near Five Ash Down?
Yes, sites like Ashdown Business Park are within our area, along with the rest of Five Ash Down. Photos and a short description are enough for a first look.
Can you take on a job at a hospital such as Uckfield Community Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does weather affect external mastic work?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Sealing in poor conditions risks adhesion failure, so we wait rather than redo work.
What accreditations do you hold?
CHAS and Constructionline are both in place, and our applicators hold CSCS cards. We’re fully insured for public liability.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
