Construction mastic across Danehill
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Phasing around occupants
- Distance, for remote addresses
- The site’s rules and procedures
- Whether old sealant has to be cut out first
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What we need to price the job
There’s no need for a formal survey. A few details are enough to get going:
- The site address and postcode
- What the building is and how it’s used
- A wide shot and a close-up of the area
- Approximate linear metres or a joint schedule
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email a schedule or drawings to discuss it first.
About our construction mastic in Danehill
Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up. Internal areas can typically carry on while the outside waits. We work on floor and skirting junctions, window and door perimeters and cladding and panel joints, and what we are called in for most is sealant knocked or painted over by other trades and different trades sealing to different standards. A specialist sealant contractor works differently from a general builder: in Danehill, that means joint design, primers and backing rod as standard.
For a site near Danehill, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Building owners, agents and FMs in Danehill
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.

Leave it or put it right?
Clearing snags piecemeal is tempting when handover is close. 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. For buildings around smaller places like Danehill, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.
Why us?
- Commercial sealant work since 2005
- Colour options checked against the specified product
- Matching to RAL references, product permitting

Questions about Danehill
Can you work at a site such as Horsted Keynes Business Park, by Danehill?
Yes. We cover Danehill and the area around it, including industrial estates, business parks and retail parks such as Horsted Keynes Business Park. Send details of the unit and the work through our quote form for a quick quote.
Is Danehill off your patch?
Not at all. Danehill is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
What accreditations do you hold?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. Tell us what site paperwork you need and we will confirm with the quote.
Do you guarantee new-build sealant work?
It carries a 12-month guarantee on our workmanship. We’re also fully insured for public liability.
How many days will you need on site?
It depends on the scope, though a typical visit typically takes a day or two on a small fit-out and several weeks on a large multi-storey package. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you use the sealant named in the specification?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
What the job involves on each surface
Internal decorators’ caulk
Caulk is easy to apply badly. Done properly, it saves decorators time and gives a clean line and keeps the snag list down.
Window and door perimeters
Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. We follow what’s specified with colours matched to the frame where needed.
When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Building and refurbishing in Danehill
Danehill is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. At about 33 miles from central London, Danehill is within reach of the capital. 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.
Older buildings in the area around Danehill, such as Priest House, 4 miles to the north-west of Danehill, need care when sealed: the product has to suit soft or historic materials. Units on estates such as Horsted Keynes Business Park, 2 miles north-west of Danehill, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. New wings at hospitals like Princess Royal Hospital (to the south-west of Danehill) bring long runs of window and panel joints to seal.
Danehill is about 5 miles north-east of Haywards Heath, in East Sussex.
