About our construction mastic in Eastry
Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list, and every return visit costs time. We seal so the snag list stays short, whatever the size of the scheme. The enquiries we see most involve a mastic package split between trades with no clear owner and sanitary sealant damaged by following trades, on brick and block movement joints, floor and skirting junctions and internal decorators’ caulk. Searching for sealant specialists in Eastry? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
For a contractor on a smaller site near Eastry, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Do you need construction mastic in Eastry?
Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink and internal caulk in a moving joint is usually the first to crack. Choosing the right product for each joint reduces that.
Things that typically lead to an enquiry:
- Frame gaps too wide for sealant alone
- Window and door perimeters that won’t pass inspection
- Inconsistent sealant finishes from plot to plot
- Failed sealant in an existing building being refurbished
New units and refits on sites such as Birnham Farm Business Centre, 1.2 miles north-west of Eastry, need their panel and perimeter joints sealed to the specification.
What your quote should include
- How the joint faces will be prepared and primed
- The named product and why it was chosen
- Whether their applicators hold CSCS cards
- What site paperwork they can supply
Keeping the joints sound
After handover, these steps help:
- Brief the final clean team to avoid blades near sealant
- Keep product details for future maintenance
- Release areas for mastic once other trades have finished in them
- Get the mastic subcontractor involved early in the programme
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean, so stick to soft cloths and gentle cleaners near sealant.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating and possibly a delayed handover. A check of every frame before decorators start is worth the time.
Why it’s worth doing now in Eastry
Getting the mastic contractor involved early pays off. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification, which avoids last-minute problems. Leave it late and they turn up on the snag list. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What you get with us
- A range of standard colours, depending on the product
- Matching to RAL references, product permitting
- Old sealant cut out, never sealed over
- One phone line for London, the South East and Scotland

What else we do in Eastry
Different surfaces, different methods
Snagging before handover
Snags normally come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately.
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line and baths are loaded where appropriate before sealing.
Our process
Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. Work in places the size of Eastry is planned as a single visit where we can. Clear photos and measurements help us bring the right products.
- We price from the drawings, specification and programme you send.
- 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.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Every joint is prepared, set to depth and sealed with the specified product.
- We close out snagging and hand over with a 12-month guarantee.
What we need from you
- Move anything stored against the joints
- Tell us your opening times and when work is allowed
- Send any specification or drawings in advance

Advice
FAQs: Eastry
Is a smaller place like Eastry outside your area?
No. Places such as Eastry are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Will you fit the mastic around our build programme in Eastry?
Yes, we work to the programme and the sequence the site sets. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you work to our specification?
The specification decides the product, and we’ll raise it if something in it doesn’t suit the joint. Specifications often reference BS EN 15651 or BS 6213.
Can you seal external joints in wet or cold weather?
External sealant needs a dry joint and a temperature within the product’s range. Frosty or damp mornings can hold up external sealing.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Do you do internal caulk as well as external mastic?
The scope comes from the specification and drawings, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Designing joint widths or choosing the specification (that sits with the designer)
- Frame gaps too wide for sealant, which the installer needs to correct
- Glazing units that are cracked or misted
Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly before you book.
Joints and surfaces we work on
- Floor and skirting junctions

Mastic packages on Eastry sites
Rainfall across the South East, Eastry included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. At about 63 miles from central London, Eastry is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.
Projects at schools like Eastry Church of England Primary School work to term dates, so mastic is programmed tightly. Historic houses such as Goodnestone Park, 3.4 miles west of Eastry, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
