How we handle mastic sealing in Rotherfield
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. If you have worn sealant at communal door frames and repeated reactive repairs to the same buildings, we can help. A specialist sealant contractor works differently from a general builder: in Rotherfield, that means joint design, primers and backing rod as standard.
In and around smaller places like Rotherfield, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Planned mastic for Rotherfield portfolios
Rotherfield is about 34 miles from central London. Within reach of London, blocks run by agents and associations are common around stations. Rainfall across the South East, Rotherfield included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
Schools and community buildings such as Rotherfield Primary School need frame and external mastic kept sound like any building. If you’re responsible for a building such as The Parish Church of St Denys, frame and door mastic needs the same attention as any other property.

Common questions from Rotherfield clients
Is Rotherfield too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
We manage a building near Crowborough station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
Can people stay in the building while you reseal?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What about access for upper-floor joints?
Every block is different. How upper joints are reached is agreed before work is booked so there are no surprises.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Glazing that needs replacing
- Asbestos-containing sealant, which we don’t remove
- Frames that are rotten, warped or broken
If in doubt, call the office on 01277 525 020 or email the details over and we’ll say what we think.
Where we work in Rotherfield

Different surfaces, different methods
Communal areas

Commercial and mixed-use buildings
Where retail and residential share a building, so phasing has to suit both. We plan around the site hours and access windows you give us.
Places near Rotherfield
What else we do in Rotherfield
Do you need mastic sealing in Rotherfield?
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone and the repair soon fails.
Site and facilities staff are often the first to spot these:
- Failed external movement joints
- Repeated reactive repairs to the same buildings
- Cracked, hardened mastic round windows on a block
- Mastic failing across several blocks on an estate
Property owners at sites such as Millbrook Industrial Estate, 1.1 miles west of Rotherfield, can have mastic renewed between lettings.
Before you book anyone
- Will failed sealant be removed rather than covered?
- What the guarantee covers, and for how long
- Which product they’ll use, and why it suits the joint
- Health and safety accreditation such as CHAS
Why it’s worth doing now in Rotherfield
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Around Rotherfield, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.
Pricing mastic joints depends on how many there are, their condition and the access. Call for a quote.

Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Rotherfield need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Before we start on site
- Tell staff and tenants when we will be in
- Move anything stored against the joints
- Tell us your opening times and when work is allowed
Quotes
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
