Mastic sealing in Ashburnham, done properly
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. The enquiries we see most involve worn sealant at communal door frames and occupiers reporting cold air round windows, on shopfronts below residential blocks, communal kitchens and washrooms and window and door perimeters on blocks. Searching for sealant specialists in Ashburnham? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Rural conversions near places like Ashburnham often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Looking after buildings in and around Ashburnham
Ashburnham is about 46 miles from central London. Within reach of London, blocks run by agents and associations are common around stations. Ashburnham is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Older community buildings, Parish Church of St Peter among them, often have frames of mixed ages whose mastic varies. For agents with blocks near Battle station, 4.4 miles to the east of Ashburnham, a block-wide mastic programme deals with frames, balconies and entrances in one go.
Ashburnham is about 5 miles north-west of Bexhill-on-Sea, in East Sussex. Ashburnham sits inside our coverage and the rest of East Sussex, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 308 places in East Sussex. We also cover Brighton, some 24 miles away.

What affects the price in Ashburnham
The price varies from site to site. It mainly depends on:
- Phasing around occupants
- The size and state of each joint
- Distance, for remote addresses
- Any access equipment needed
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Whether the building will be occupied during the work
- Where the site is, with the postcode
- Asbestos survey details if the building is older
- Drawings or a marked-up plan, if available
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or email us if you’d rather talk the job through.
Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Mention RAMS, insurance or CSCS requirements up front
- Ask residents or tenants to report leaks and draughts early
- Start inspections with the most exposed faces
- Keep bins and bikes away from communal door frames
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.

What else we do in Ashburnham
Different surfaces, different methods
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Fresh joints make shared areas look looked after.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Diagnose, treat, sign off
Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. For work around Ashburnham, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Getting the site ready
- Agree which areas must stay open
- Have the specification and drawings to hand
- Tell staff and tenants when we will be in

Advice
When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Substrate edges that need repairing first
- Glazing that needs replacing
- Leaks from above rather than through a joint
Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly before you book.
What we seal
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Shopfronts below residential blocks
- External wall and movement joints
- Window and door perimeters on blocks
- Balcony and threshold joints
Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Ashburnham: questions and answers
Is a smaller place like Ashburnham outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Will you price a mastic programme across our Ashburnham portfolio?
Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
Do you supply RAMS and insurance details?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
