Common questions from Five Ashes clients
Is a smaller place like Five Ashes outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Is Station Road Industrial Estate, near Five Ashes, within your area?
Yes. Our area takes in Five Ashes and its surroundings, with estates and business parks such as Station Road Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
What joints do you seal on a new build?
It depends on the specification, but frames, sanitary, kitchens, caulk where specified and snagging are typical.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How we handle construction mastic in Five Ashes
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. After that, the joints are prepared and sealed to the specification. If you have a long mastic snag list close to completion and frame gaps too wide for sealant alone, we can put it right, on floor and skirting junctions, brick and block movement joints and sanitary and kitchen joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Five Ashes it comes down to the same thing: the right product in a properly prepared joint.
In the countryside around places like Five Ashes, 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.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What happens if it’s left?
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go, and avoids repeated visits. Snagging can be priced as a separate stage. Older rural buildings around Five Ashes move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Pricing mastic packages depends on quantities, condition and access. Call for a quote.
What you get with us
- Old sealant cut out, never sealed over
- A range of standard colours, depending on the product
- Work to your specification and the manufacturer’s guidance
- CSCS-carded applicators
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Don’t force external sealing on a damp or frosty day
- Flag uneven or tapered frame gaps early
- Stick to the specified sealant rather than a generic substitute
- Brief following trades on areas that have been sealed
The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault which is why protection after sealing matters.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure, so the installer needs to correct it first. We raise them during our first walk of the area.

How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Joint width, depth and condition
- Phasing around occupants
- Which sealant the job calls for
- Quantities, in metres or numbers
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What to include in your enquiry
Good information means a firmer quote. When you get in touch, include:
- Anything awkward about access or site hours
- The postcode of the building
- Rough lengths or quantities, or drawings if you have them
- Photos of the joints, close up and from further back
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or email drawings and photos with what you know.
Different surfaces, different methods
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. Joints are sealed smooth so they’re easy to clean.
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit, depending on what suits the programme.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Rework caused by others damaging completed areas
- Deciding which fire-stopping product a penetration needs
- Defective windows, doors or glazing units (the supplier or installer’s job)
If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer.

Construction mastic in Five Ashes: the local picture
The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Five Ashes lies roughly 37 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
For contractors at a school such as Five Ashes CofE Primary School, sealing has to be finished before term starts. Recladding or extending a unit at a site like Station Road Industrial Estate, 2.7 miles south-east of Five Ashes, brings panel joints and frame perimeters into the programme. Hospital estates such as Crowborough War Memorial Hospital (to the north-west of Five Ashes) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Five Ashes is about 4 miles south-east of Crowborough, in East Sussex. Our applicators travel to Five Ashes for work on mastic packages. Our East Sussex coverage takes in 308 places, large and small. We also cover Brighton, some 19 miles away.
